Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a soft finishing method with excellent water absorption. More specifically, in fiber materials such as cellulose yarn fibers such as cotton, rayon, hemp, etc. alone, blended, interwoven, interwoven, etc.
The object of the present invention is to provide a soft finishing method with excellent water absorption, particularly in the same bath processing with a fixing agent after deep color dyeing, where it is difficult to impart water absorption, or in post-processing after treatment with a fixing agent.

Until now, with regard to fiber materials such as cellulose fibers such as cotton, rayon, hemp, etc. alone or mixed, interweaved, interwoven, etc., there has been a relationship between the dyeing process and the type of softener used. That is,
Generally, anionic yarn softeners have been mainly used for white goods, and cationic yarn softeners for both light and dark colors have been mainly used.

On the other hand, non-ionic soft yarns are also used, and are generally used for colored goods, but the amount used is relatively small, except for special uses as softeners combined with resins.

In some cases, anionic softeners are used as a post-processing agent for fixing agents for dark-colored products.

However, in recent years, there has been a strong demand for water absorbency, especially for both white coats and outer coats.If we look at this individually, we find that when using anionic yarn softeners for white coats, it is relatively water absorbent. However, due to its N absorption mechanism, cationic yarn softeners, which are often used for colored fabrics, have a cationic group that is a hydrophilic group that tends to affect fiber properties.
(Since it is adsorbed onto the membrane and orients hydrophobic groups to the outside, it has been extremely difficult to impart water absorption properties except for a few special types.

In addition, it is difficult to achieve both water absorption and texture with the generally used non-ionic yarn softener.In a more special case, an anionic yarn softener is used for softening after processing. In this case, the anionic yarn softener is adsorbed where the fabric surface has been cationized by the fixing agent, causing the hydrophilic groups to lapse in a manner that causes a complex.The present inventors have worked diligently to solve these problems. As a result of research, the present invention was arrived at.

In other words, the following general formula (sword, (2) and (3)) can be used for co-bath processing of cellulose yarn fiber alone or blended, interwoven, or interwoven fiber materials with a fixing agent, or for post-processing after treatment with a fixing agent. We have discovered a method for softening and finishing with excellent water absorption, which is characterized by using a softener containing at least one of the compounds represented by:

--1------il+ (In the above formula, R1,
, R2, R3, and R4 each represent a saturated or unsaturated hydrocarbon group having from 8 to 22 carbon atoms, each having the same size or different size, and A and B are an oxyethylene group or an oxypropylene di-N group. , n represents an integer of 1 to 20, and m represents an integer of 0 to 20.

Furthermore, the condition is that +A-)-nt B÷〇 (in the preparation, at least 50 Hr range % or more of oxyethylene groups) are contained.

In addition, x&ma represents an alkali metal or ammonium thread or an alkanolamine group, and Y represents a hydrogen atom, an alkali metal, an ammonium group, or an alkanolamine group. For use in dark colored products, which have been considered difficult, i.e. for fixed bath processing or post-fix processing.
By containing oxyethylene chains within a predetermined range, the yarn can be used as an anionic yarn softener and has both water absorbency and a good hand.

This is not only because of this, but also because of the high compatibility between anionic softeners and cationic fixing agents.
Regardless of the bath or post-processing, the adsorption of the softener to the fibers is significantly increased, resulting in very little softener remaining in the treatment bath, which greatly contributes to reducing the wastewater load. be.

Examples include synthetic or natural higher alcohols such as docosyl alcohol, and higher fatty acid reduced alcohols such as beef tallow fatty acid reduced alcohol and tall fat fatty acid reduced alcohol.

In the present invention, the softener used is prepared by adding ethylene oxide and propylene oxide to such a higher alcohol, and this is done by a conventionally known method. However, in this case, the oxyalkylene chains obtained from this must contain at least 40% or more of oxyethylene chains! J1 is an essential requirement for obtaining water absorption and solubility in the same bath as the fixing agent.

That is, if the content of oxyethylene chains is less than 40% by weight, the water absorption and the same-bath compatibility with the fixing agent V1- will decrease, which is unskillful. In addition, the clavicle of the oxyalkylene group (
If the mn number (in the general formula) is 2 or more, the texture obtained will be poor, so it is wise to set it to 20 or less. In order to obtain a particularly excellent hand, it is particularly preferable that the number is 15 or less.

Next, the general formula 11+ used in the present invention
, +21 O and (3) can be produced by any of the following industrially known methods.

General formula fll C. Sulfate the alkylene oxide adduct of the above-mentioned higher alcohol with 98% sulfuric acid, chlorosulfonic acid, anhydride (fluidic acid, sulfamic acid, etc.), add caustic soda, caustic potash, ammonia sweetness or monoethanolamine, Diesterification or monoesterification of alkanol akylene oxide with unsaturated dibasic acids such as jetanolamine and triethanolamine, respectively, and addition of bisulfite, etc. to the unsaturated bond. In the case of a monoester, the remaining carboxylic acid wood chips can be obtained by wiping the mixture and appropriately neutralizing it with caustic alkali, ammonia, alkanolamine, etc.

In the present invention, the fixing agent that is treated in the same bath as the softener or in advance is a direct dyestuff that is commonly used for the purpose of increasing fastness when dyeing cellulose yarn fibers in deep colors. Alternatively, it refers to a type called polycation yarn or polyamide amine yarn for use with reactive dyes.

According to the present invention, the blending of esters of polyalcohols such as sorbitan or glycerin with higher fatty acids and fats and oils such as hardened beef oil, which have been commonly used as softening ingredients in fabric softeners, is essentially unnecessary. Although necessary, these can be used in combination depending on the situation. Furthermore, for the purpose of preventing thread breakage during heavy sewing of stockinette, etc., emulsions of paraffins, silicones, polyethylenes, etc. may be mixed and used as necessary.

The present invention will be specifically explained below using examples.

(Parts and % are based on vehicle weight.) Example 1 Ethylene oxide (hereinafter referred to as 20 mol of EO, 25
It was added in molar proportions. After that, the chlorosulfonic acid was added dropwise to each of the OH ends of the OH wood in a Mitsu flask at a temperature of 25 to 30°C, and the sulfation reaction was carried out with stirring. After aging for 20 minutes, it was poured into a caustic soda aqueous solution and neutralized at 45°C or lower, and the pH was adjusted to 9 with a 1% pure aqueous solution.

These compounds and an equal number of maleic anhydride were put into a three-piece flask equipped with a nitrogen introduction tube and a dehydration device, and 0.3 of the total amount of maleic anhydride was added.
% P-)/reninsulfonic acid was added as a catalyst, and the esterification reaction was carried out at 180 to 185° C. while gradually increasing the temperature in a nitrogen stream until the acid value became 8 or less. Furthermore, these reaction products are mixed with 1F sodium sulfate in an amount equal to the raw material maleic anhydride, 3.5 times the amount of water, and 15% of the total amount of yarn.
% of isopropyl alcohol and dilauryl sulfosuccinate sodium salt as a reaction accelerator to give a concentration of 5% of the purity of the composition.A three-piece flask was equipped with a rapid flow device to inject isopropyl alcohol. A fast flow reaction was carried out by heating to boiling point. After continuing the reaction for about 4 hours under these conditions, each thread was checked for free sodium bisulfite, and none was detected, so each thread was cooled to further reduce the composition purity to 25%.

EXAMPLE First, 5 moles of PO were added to 1 mole of reduced beef tallow alcohol/I in an autoclave in a conventional manner, and then 5 moles each of EO was added.

They were added at a ratio of 10 mol, 15 mol, and 20 mol.

Thereafter, these compounds and the same mole of maleic anhydride were put into a Mitsuro flask equipped with a nitrogen inlet tube and a reflux device, stirred and heated under a nitrogen stream for a few hours, and the maleic anhydride was heated to 110°C. The ring-opening monoesterification reaction was continued until each specified acid filli was reached.

Then, they were cooled and neutralized by adding jetanolamine of equal h1 to the acid value at 30C or less, and then 30% of sodium bisulfite was added to the same amount of maleic anhydride.
．． The mixture was dissolved in 5 times the amount of water, added and mixed to each of the threads, and heated to 75° C. while stirring once to react.

After reacting for 3 hours, each thread was checked for free sodium bisulfite (1 to 1), but none was detected, so each thread was cooled and further added with water to make the composition purity 25'10. Diluted to give a specific example Zamp/l/G (PO5 mol, Eo 5 mo/L/), same H (PO5 mol, 'EO
