Description

The invention relates to a method by means of which textiles can be made oil- and water-repellent as well as dirt-releasing. The process consists in applying a dirt-releasing polymer and an oil- and water-repellent material to the textile material. Preferably, a textile resin and a textile resin catalyst are also applied to it and the textiles treated in this way are subjected to conditions in which the resins are hardened.

State of the art

For about ten years the textile industry has made significant technical progress in the high-tech finishing of textile products. There were

Numerous processes developed, the K-I hurdles and other specially treated textile products impart properties that are easy to care for as far as possible facilitate. Examples of such advances are the so-called "wash and wear" products, which are referred to here as pre-hardened textile goods, and the textiles with permanent ironing folds that are in hereinafter also referred to as post-hardened goods. These properties are common to textile products by applying resinous substances. The resinous substances are thereby applied to the textiles applied and later crosslinked on it under the action of a suitable catalyst. Depending on the time in which the crosslinking reaction takes place, one obtains either an easy-care one or one with permanent creases provided goods. The pre-crosslinked textiles are those in which the crosslinking reaction takes place before the processing of the Fabric has been added to a piece of clothing or another commodity. The post-cured textile products are those that were only subjected to the crosslinking reaction after the fabric became a clothing ~ piece or another commodity had been processed <>

As far as the fiber content is concerned, both the pre-crosslinked and the postcrosslinked textiles can be of the most varied natural or synthetic fibers

keep. At present, however, most of these products contain synthetic, man-made fibers. These Synthetic fibers are extremely advantageous for these textiles over a product that is only natural Contains raw materials. On the other hand, however, it is a disadvantage that the synthetic fibers have a tendency to Soiling and that greasy or oily substances with which the garment comes into contact during normal wear is eagerly accepted by the oleophilic synthetic fibers. Because these synthetic fibers also have hydrophobic properties at the same time, then these oily or fatty substances are extraordinary difficult to remove. Therefore, if the garment is stained from such substances, it cannot simply be Wash, but it has to be dry-cleaned if the stains are really to be removed to be brought. But even if there are no stain-producing substances, this leads again to | got washing a synthetic fiber garment baw. Items of laundry mostly to the fact that this takes on a cloudy gray color, which is based on the fact that it removes the dirt contained in the washing water. This process can be called "dirt recovery" ·

The mentioned pollution problem led to another technical innovation in the textile field, namely

10983S / 1SQ1 " ⁴ "

an easy-care or non-iron textile product, which at the same time has "dirt-releasing" properties. The terms "dirt-releasing" or "dirt-releasing" do not denote absolute resistance against soiling, but only refer to the property that a substance, once it is soiled, can be cleaned using the normal washing process. Also, have fabrics or garments that are treated like that ™ are that they have dirt-releasing properties the property of not absorbing dirt from the washing water, that is, that contained in the washing water Dirt does not settle on the garment again during washing «,

In parallel with the development of easy-care and non-iron fabrics, work was carried out on textiles to impart the ability to repel oil and water. Many different means have been developed for the textiles "» Water resistance to be borrowed from examples of such Impregnating agents are: (1) washing emulsions j (2) impregnating agents based on pyridine compounds, long-chain fatty acid amides, mixtures of resin and waxJ (3) silicones; (4) organochrome compounds! (5) fluoro chemicals.

The fluorochemical type waterproofing impregnants are probably the most widely used today. Two commercially available means are mentioned

of this type, namely FC-208, the fluorocarbon component of "Scotcbgaeid" products (manufacturer Minnesota Mining and Manufacturing Company) and "Zepel", one of EGG. du Pont de Nemours & Co · sold water-repellent fluorochemical. The ones treated with the fluorocarbons In addition to being water-resistant, chemicals also have the ability to repel oil to a certain degree «.

A disadvantage of water and oil repellent textiles is that they are difficult to stain through Washing to remove. The water and oil repellent properties naturally make the product both hydrophobic and hydrophobic oleophobic and mostly resistant to any kind of Moisture, fat or oil. Under normal circumstances, this resistance means some protection against Pollute. However, if oil is rubbed into the fabric under pressure, for example, such stains can occur Washing can no longer be removed, as the substance is hydrophobic I and the water required to remove the oil

These dirt spots can can be partially removed by dry cleaning, but the cleaning process again impairs the water resistance of the clothing. On the other hand, such dirt spots cannot be removed by normal washing.

It was not previously thought possible that a textile product could have both oil and water-repellent properties and be "wear-release" ¹¹ The soil release property, on the other hand, has been believed to be bound to fibers which are inherently hydrophilic, or which have been treated appropriately The direct opposition to releasing dirt.

Finally, the invention has set itself the goal of textile products including synthetic To provide polymer fibers that not only have water- and oil-repellent and dirt-releasing properties, but also have permanent ironing properties and / or are iron-free or easy to care for.

Overview of the invention

According to the invention, a textile material has water-repellent, oil-repellent and dirt-releasing properties issued with the help of a process that consists in placing a dirt-releasing material on the textile material Applies polymer and a water- and oil-repellent material. Preferably the textile material is conditions subjected, in which textile resins are cured. Appropriately, one also brings on the textile material a textile resin and a textile resin catalyst.

The method according to the invention can be used for a wide range of textiles, i.e. for fabrics that Made exclusively from naturally occurring fibers, for fabrics made exclusively from synthetic polymer fibers are manufactured and also for mixed products made of natural and synthetic fibers. The method can be applied to textile products with a Cellulose fiber content ^, e.g. on cotton, viscose, regenerated cellulose etc. Examples of synthetic fiber textiles that have been used with success in performing the

Processes according to the invention which can be used are those made using polyamide, acrylic acid and especially polyester fibers, ie various types of "Dacron" (a registered trademark of EI du Pont), "Fortrel", (a registered trademark of Celanese), "Kodel" (a registered trademark of Eastman Kodak), etc. mixtures of natural and synthetic fibers which can be used for the manufacture of textiles according to the invention, are i include those with 50% polyester and 50 io cotton or with 65 ° Polyester and 35 # cotton etc.

Various theories have been expressed for the correct structure of textiles with optimal water resistance. According to one of these theories, the fabric should be woven in such a way that the warp and weft elements are very close to one another while, according to another theory, a normal or even loosely woven fabric is attached best suited for a water repellent treatment. However, the invention is not to any particular one Structure of the fabric bound, but relates to the treatment of a textile material in such a way that one has a Combination of water-repellent, oil-repellent and dirt-releasing properties. As an impregnating agent, which make the material water and oil repellant, many substances can be used, if they are present >

The amount of textile resin to be used is primarily determined by the later use of the clothing or other objects that are to be made from the treated fabric. Very small amounts of resin lead to a certain improvement, larger amounts of course lead to greater improvements, but the larger amounts of resin generally impair the feel of the goods. The amount of resin to be used is therefore preferably one which gives good crease resistance and makes the product dry smoothly without impairing the feel. According to the invention, the amount of textile resin in the impregnation bath can vary between 2 and 30% by weight. The amount of resin applied to the goods is in the range from 2 to 20%, preferably from 4 to 9 %, based on the dry weight of the goods.

The catalysts to be used according to the invention must correspond to the textile resin in question which is based on the textile material is applied. For example, if the textile resin has a functional group that is below is reactive to acidic conditions, an acidic catalyst is used. Accordingly, if a functional group is present, which reacts under alkaline conditions, a basic catalyst is applied. If both types of functional groups are present in the textile resin, both acidic and basic ones can be used Use catalysts, then individually or together

can be added. If they are added together, one of the catalysts must be latent Acting as a catalyst, i.e. one that does not set its own reaction in motion as long as the opposite reaction Reaction continues, but is later activated under appropriate catalytic conditions «,

The catalysts used to activate the acidic or basic reactive groups are those commonly used to control the reaction of textile resins containing the group in question, to activate with the hydroxyl groups of cellulose. It is preferred to use latently acidic or basic catalysts, i.e. compounds which, under the conditions prevailing during hardening, produce an acidic or have a basic character. The best known acid-acting catalysts are the metal salts, e.g. Magnesium chloride, zinc nitrate and zinc fluoroborate as well as the amino salts, e.g. monoethanolamine hydrochloride and 2-amino-1-methylpropanol nitrate

The acting as a base catalyst is preferably a compound between the basic reactive Group and the hydroxyl groups of cellulose does not cause any significant reaction under normal * acidic conditions, but under the conditions described above, such as elevated temperature and some other activating Measures, e.g. when using a different chemical compound, initiates a significant reaction.

The catalyst acting as latent base according to the invention comprises alkali metal salts such as alkali carbonates, e.g. sodium carbonate, that is neutral to mildly alkaline and has a pH value of around 8.5 on the goods, for example however, at temperatures above about 80 C it decomposes to the more basic sodium oxide that is used for hardening higher temperatures brings a substantial heat in motion. Sodium carbonate can be used for this reason alone because of this connection in the textile product evoked pH is usually not sufficient under normal temperature conditions to achieve the desired degree of implementation.

However, if textiles with a basic reactive group are kept at pH above about 10, this occurs a decomposition, so that when using basic reactive compounds neutral or mildly alkaline Catalysts are preferred

Other catalysts that act as bases are potassium bicarbonate, potassium carbonate, sodium silicate, alkali phosphate, such as sodium or potassium phate, barium carbonate, quaternary Ammonium hydroxides and carbonates, e.g., lauryl trimethyl ammonium hydroxide and carbonate and the like.

The amount of catalyst to be used corresponds to that which is usually used to activate the

Reaction between textile resins and the hydroxyl groups of the Cellulose used; for example, up to about

15% by weight of an acid acting catalyst in the impregnation bath, the preferred amount being between 1 and about 7 ° . A useful range for the catalyst acting as the base is generally from about 0.2 to about

16 ^, preferably between 2 and 16 ^, which is the usual amounts is equivalent to. The amount of catalyst to be used depends in part on the temperature at which the reaction is carried out as well as the amount of catalyst that is consumed for the reaction. For example, if basic catalysts and if the reaction releases a strongly acidic group, the amount of base applied to the Textile material is applied, at least sufficient to ensure that an excess of base over the amount which by the

strongly acidic group is consumed, remains. -

The term "dirt release" used in connection with the invention relates to the suitability of the relevant Textile goods, during washing or other appropriate handling, dirt and oily or greasy substances that sioh have scheduled to release. The application of the invention does not in itself prevent the build-up of dirt or oily or greasy substances on the textile goods, but this prevents permanent adhesion and in this way the Textiles that are difficult or impossible to clean beforehand for

109836/1601 -18-

makes a successful cleaning suitable. During the pre-f Although this cannot be explained in theory, it can be observed in practice that the introduction of treated textiles in washing water containing detergent initially leads to an accumulation of the oil on the surface of the goods. The wash water Is naturally basic and in this state it was found to be the most suitable for releasing the dirt. the The above-mentioned oil or fat droplets then detach from the material and rise to the surface of the washing water. This The phenomenon occurs in washing machines in which the goods are constantly moved, but can also occur under static conditions watch. A strip of a blended fabric made of polyester and cotton that has been soiled with crude oil and which has been treated according to the invention For example, the oil released when it was immersed in a detergent solution without stirring. The oil clumps first on the fabric, then separates from it and rises to the surface of the solution »

An additional feature of the invention is the prevention of the absorption of dirt from the wash water. One of the biggest Disadvantages of the synthetic polymers are that even after the dirt has been removed by Y / ash, G3-fahr continues consists that the dirt is deposited again from the ash water on the fibers before the garment is removed will. It was found that the ability of the textile material treated according to the invention to remove dirt to release after several times

washing goes back. However, even if this decline has already occurred, it has been observed that the ability to to prevent the re-absorption of the dirt from the wash water, still remained in force »This Phenomenon can also hardly be explained? ee was however found that the interfering dirt is negatively charged and it can be assumed that there is enough acid on the textile material remains to repel the negatively charged dirt particles · ™

Some of the fabrics made with the aid of the invention Process can be treated, can not be easily removed from their environment and wash in washing machines} this is e.g. for polishes the case. Still other materials are either subject to washing machine treatment their structure or their appearance attacked · Substances of this type can, if treated according to the invention Bind, effortlessly to be cleaned on the spot, "by brushing the stained areas lightly with a solution rubs off a commercially available detergent in water

According to the invention, the polymer used for releasing dirt is selected from a large number of different polymers "Compounds such as acidic polymers, polyesters with low molecular weight, etc. The polymer used should, if possible, around the fibers of the textile material

make a movie around. It is desirable for the film to have a certain softness, because if it is too hard, the feel of the textile material can be adversely affected. Furthermore, the film should preferably have hydrophilic properties and be at least partially water-insoluble. If the film were water-soluble, it could of course easily be washed off the fabric. The polymer from which the film is formed can, however, be water-soluble when applied with a textile resin, because during the curing process the polymer, even if it is water-soluble, is converted into a water-insoluble film. Even if the polymer is applied to a substrate without additional textile resin, it can be water-soluble if the substrate is such that the release of dirt only has to take place once. An acid content of at least 10% by weight, preferably at least 2o% by weight, calculated as acrylic acid, in the soil-releasing polymer from which the film is formed is desirable. Ee was further observed that acidic polymers which promote Schmutifreigabe, a ratio of carbon atoms to the acid groups have in the unit, which in the.

Acid polymer is subjected to conditions for curing the textile resin, the durability of the ability to release dirt is increased. This ability is also required by the presence of a textile resin catalyst during the curing of the textile resin. In addition, the equipment for soil release on a substrate is substantially more durable when the Säurepolymerisat in the presence of an aminoplast textile resin is subjected to conditions to cure the resin μ. It is known that the film, the hydrophobic synthetic fibers contained in the textile material, without any order to RESPOND ^s "What was so far not yet explain covered ^, the durability is dirt release property. It is known that some kind of reaction takes place between the acid polymer and the textile resin, but so far only speculations can be made about the reaction mechanism. In addition, there may be a crosslinking between the cellulose molecules and the acid polymer, '

or it can also just be a strengthened physical bond between the textile resin and the acid polymer act outside of their responsiveness and beyond.

The polymers leading to the release of dirt, similar to the textile resins, give the goods a noticeable improvement even in very small quantities. If the amount of polymer applied to release dirt is increased, the capability of the product increases with the 109835/1601

Wash to release the dirt. The upper limit for the amount of polymer to be used for this purpose is determined by economic considerations and by any disruptive effects on the Goods, e.g. on their softness to the touch. In practice, the amount of polymer to be used depends on first and foremost after economic success.

The acid polymers are, generally speaking, emulsion polymers with various proportions of pesticides, which are normally in the range from about 25 to 50% by weight. The polymer emulsion should be in the impregnating bath (BEZW in another application medium.) In the range of about 2.5 to 4o wt -. ° / o be present. In other words, should the substrate is about o, 25-5 wt .- $, preferably from 1 o to 1.5 wt .- / o to Säurepolymerisat-Peststoffen be applied, the percentages being based on the dry weight of the textile W based tilgutes are.

The one for impregnating the textile material according to the invention The preparation used is not limited to the components mentioned above, e.g. the textile resin, the Textile resin catalyst, the soil-releasing polymer and the water-repellent compound, limited. In addition, other ingredients can be used, such as emulsifiers, wetting agents, plasticizers etc. as well as numerous other compounds that affect the physical properties of the textile influence.

The preparations can be applied to the substrate in any desired manner. Preferably the solution e.g. applied to the textile material by padding, as this operation is easiest at the relevant stage is feasible. The preparation can also be sprayed on as a liquid or the substrate can, if this is appropriate treated with vapors of the compounds or immersed in the impregnation solution.

In general, the system is set so that the goods from the pad bath at $ 30-100 of their dry weight Absorbs liquid. The amount of liquid absorbed from the padding bath is preferably 40-60% by weight the best results are achieved with it, as has been determined ο

If on the substrate, e.g. the textile, in addition to the polymer applied to release dirt and a Fluorocarbon compound as a water-repellent agent or the aminoplast textile resin is applied, so can all substances mentioned are applied simultaneously from the same padding bath. However, it is a simultaneous It is not necessary to apply and you even get particularly good results if you first use the dirt-repellent Polymer, and only then apply the textile resin and the waterproofing compound one after the other, whereupon the textile resin is hardened. Bring the different ones Impregnating agent separately, whereby the textile resin is applied and cured first and the dirt-

peeling polymer and then applying the waterproofing compound individually, one achieves a very easy removal of the dirt; however, this property is not nearly so in this case permanently, as if you had all the components at the same time applies, or if, with separate application, the textile resin, the dirt-releasing polymer and the waterproof making agents are already in place while the textile resin is cured.

Depending on your wishes and the desired end product, you can use the textile resin, the dirt-releasing one Apply the polymer and the water-repellent agent separately or simultaneously. When treating fabrics that are to be processed onto work clothes, for example, it is desirable that the equipment be so durable as possible, so that the dirt-releasing properties remain as long as possible. In this case it would be either a simultaneous application or a separate application, in which the soil-releasing polymer is added first, attached. Should on the other hand the commercial product impregnated according to the invention is not E.g. washed or cleaned every week, the desired property should probably consist of " that the object exhibits particularly good dirt release from the start. An example of this would be Fabrics for the interior upholstery of automobiles, for wall hangings and the like be to apply the textile resin first and then after

this is hardened to apply the polymer causing the dirt release and the water-repellent agent, or only the dirt-releasing polymer, the water-repellent agent and those described above To apply additives if textile resin is not to be used. However, one must be aware that under such conditions the water-repellent and soil-releasing properties are less durable than when j these properties are achieved by applying the impregnating agents at the same time.

The door parts associated with the application of the method of the invention come in virtually any textile any shape, e.g. piping, yarns, threads, fabrics, or already processed products, e.g. Clothes etc.

Garments made from the fabrics treated according to the invention do not require any additional work steps, "

but only those used in the manufacture of the usual permanent ironing clothes normal treatment. In other words, the garment can be placed on a conventional device, e.g. Apply the desired folds on a Hoffmann press upd. The press cycle employed is common in the industry and generally includes briefly pressing the garment, followed by a hardening treatment in the oven.

6β Conditions are imposed on the garment which the textile resin is cured.

In all of the working methods described above, the curing of the textile resin can also take place before production of the garment are brought to a conclusion, whereby one obtains an easily washable, easy-care fabric, which is water and oil repellent and easily releases dirt when washed.

The working instructions according to types I, II and III relate, as can be seen, to the application of the invention Method on a textile material which is to be prepared in such a way that it repels both water and oil, easily releases the dirt during washing, can be subjected to a permanent ironing process and / or is easy to care for, However, these modes of operation are not intended to imply a restriction of the method, as can be seen from the rest of the text of the description and the claims emerge

The drying temperatures, which are not sufficient to get the catalysis going, depend of course on the particular catalyst used.

In general, however, the drying step is carried out at a speed of about 9-64 meters per minute Temperatures between about 107 and 150 °, preferably in a tenter frame. The area for the dry temperature "overlaps" to some extent with the above-mentioned range for the hardening temperature drying in the overlapping part of the areas for drying and curing, it is important that ^

no premature curing of the textile resin took place here Drying the substrate at higher drying temperatures, care must be taken to ensure that the substrate is not heated is avoided for a long time, since otherwise catalysis takes place, which leads to an at least partial hardening of the textile resin would lead.

If a textile resin with ethylene unsaturation is applied to the textile material, the invention can be used according to the impregnated material can be post-treated with the aid of known irradiation techniques. An isolated core transformer operated at a voltage between 100,000 and 500,000 electron volts can be used successfully to irradiate the textile material. Such a transformer is sold by High Voltage Engineering Corporation, Burlington, Massachusetts. The amount of ionizing that is necessary according to the invention

Irradiation is at least 32 EV for each ion pair formed. Thus an irradiation of 32 volts and effective about it. According to the invention, both particles of high energy and ion irradiation are suitable. The radiation dose preferred according to the invention is in the range from 100,000 rads to 100 megarads (one rad is the Amount of high energy irradiation resulting in an energy absorption of 100 ergs per gram of absorbent material

results). However, / irradiation dose in the range of 0.5-5 megarads is particularly preferred.

The curing of the textile resin is effected by subjecting the textile material impregnated with the resin to conditions in which the catalyst causes a crosslinking reaction between the functional groups of the resin and hydroxyl groups from the cellulose of the textile material and the resin hardens to the thermoset state. If textiles that are 100 $> synthetic are treated, the resin adheres to the material and is converted into the heat-cured state.

Hardening is mainly effected by temperature, and as a general temperature range are Sufficient up to about 300 ° C. The hardening medium that provides the necessary temperature can be any Be a substance that affects both the textile material and the other components of the hardening system e.g. is inert to hot air, steam, etc. In cases where the textile resin has two different types of

table in two stages, the first of which is carried out at a lower temperature than the second, and at a temperature which is insufficient to initiate the second type of catalysis. The hardening then takes place, for example, in such a way that the alkaline catalysis starts in a first stage, whereupon a second hardening stage begins, in which the acidic catalysis takes place and the resin is finally cured. %

The duration of the various stages of work can vary can be very different depending on the substances used, but in every situation the treatment time is the one which is necessary to bezw the appropriate reaction. the To effect hardening of the textile resin} it is preferably between 1 and 30 minutes.

The following examples, in which parts and percentages mean parts by weight and percentages by weight, explain preferred embodiments of the invention without having a restrictive character.
