In general, flocking is a method of expressing a pattern by planting on a desired pattern using a fine fiber pile yarn, and classified into two types of flocking and floppy depending on the working method, and flocking is directly woven into the fabric, such as velvet. It gives a soft texture to increase the value of the product. Usually, the fabric wound in roll state is drawn out at a constant speed, and the adhesive is applied to the surface of the fabric, and the pile yarn in which the adhesive-coated fabric passes evenly under the hopper is uniformly dropped and supplied from the hopper by the electrical action of the electrode plate. It will fall upright, so that the pile yarn is vertically bonded and fixed on the fabric to which the adhesive is applied to be planted.

2. Description of the Related Art In the past, a method of printing a dyeing material using a dye in order to express a pattern having a predetermined color on a portion where the flocking is planted has been conventionally performed.

As described above, the conventional printing method applied to the flocking fabric is a dyeing method in which the textile material is partially colored and the pattern is dyed, and the dyeing is performed by stamping the printing paste containing the dye in the textile material. Traditional printing works consist of printing, steaming, washing and drying. In order to perform printing, the compounding process of compounding dye must be completed to make color, and it is blended while controlling the amount of dyeing material applied to fabric, and it is not only dyes, but also ingredients and pharmaceuticals. Toning back.

Printing operations are mainly printing, steaming, washing and drying processes. The printing process is a process of pouring a dye on a printing stand and printing a pattern for each color. The steaming process is a steam steaming process for fixing dyes coated on fabrics, which increases dyeing and fastness. Washing process is a process of washing printing fabrics, and removes unneeded undesired matter, dust, blemishes, etc. during printing. The drying process is a process in which a washed fabric is put into a drier and completely dried, and a flat and uniform process is also performed using a tenter.

However, according to the conventional printing method as described above, after the printing process is completed, the locking fabric has been inevitably performed a washing process and a dehydration process to wash the printing fabric through washing with water, and in order to do this, the printing fabric is washed. There was a problem of separately providing a washing device for supplying and washing the washing water, and a dehydration device for dewatering the washed fabric, and delayed production period and manpower consumption due to the addition of a work process for washing and dewatering. There was a problem that the efficiency of the work such as economic burden is reduced.

Therefore, there is an urgent need to provide a printing method for the locking fabric, which performs printing on the flocking fabric, but does not perform washing and dehydration processes, and thus, drying and steaming processes are carried out to simplify the work and reduce the scope of the apparatus. Should be.

According to the printing method of the flocking fabric of the present invention, the acid dye is dissolved in water, and then mixed with a synthetic foil to perform the flocking on the flocking fabric, but the washing and dehydration processes are not performed, and the printing is completed by a drying process and a steaming process. There is a useful effect that can be expected to ease the work and generate economic benefits by reducing the process.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the printing method of the present invention locking locking fabric.

1 is a flow chart of the printing method of the present invention locking locking fabric, Figure 2 is a schematic diagram showing a printing method of the present invention locking locking fabric.

As shown in FIG. 1, the printing method of the present invention lock locking fabric is formed by forming a bonding layer on the surface of the fabric, and performing a flocking process for spraying the pile yarn is fixed while the pile yarns are planted in the form of a straight hair on the adhesive layer. In the printing method of the locking fabric made by drying the adhesive layer as possible, 30-50% by weight of an acid dye solution made by dissolving an acid dye of a predetermined color in water of 80-100 ℃, 45-65% by weight of synthetic paints, 0.5 yuan A dye preparation step (S10) of preparing a dye composition 100 by mixing -2 wt% and 3-7 wt% of urea; A dyeing step (S20) of cooling the dye composition 100 to room temperature and performing printing according to a pattern on the locking fabric 200; A drying step of drying the printed locking material 200 by placing it in a cylinder at 70-100 ° C. for 30 to 90 seconds (S30); The dried after-locking fabric 200 is a heat-treatment step (S40) for dyeing by heat treatment for 20-35 minutes at a temperature of 90-110 ℃.

As described above, the flocking fabric 200 forms an adhesive layer on the surface of the fabric, and performs a flocking process of spraying pile yarns, thereby drying the adhesive layer such that the pile yarns are fixed while being planted in a straight line on the adhesive layer. Meaning, it is used for the same purpose as the carpet.

Dye preparation step (S10) is a step of preparing a dye composition 100 for printing on the locking fabric 200, an acid dye solution made by dissolving an acid dye of a predetermined color in water of 80-100 ℃. It consists of 50 weight%, 45-65 weight% of synthetic foils, 0.5-2 weight% of yam, and 3-7 weight% of urea.

Acid dyes are generally referred to as water-soluble dyes with acidic groups, and are made from intermediates with acidic groups or sulfonated with fuming sulfuric acid. Azo, anthraquinone, triphenylmethane, xanthine dye, and the like are mainly azo dyes. The main uses are dyeing of wool, and there are various uses such as leather, cellulose, lake pigments, inks, food coloring, indicators, and the like.

In general, color fastness is higher than that of basic dyes, and dyeing is performed by ion bonding between the amino group of the fiber and the anion of the dye.

The acid dyes as described above are dissolved in water at 80-100 ° C. to form an acid dye solution. The acid dyes and water may be formed in various ratios according to the desired color and transparency. The temperature of the water is to be provided at 80-100 ℃ in order to ensure that the acid dye is uniformly and quickly dissolved in water, not limited to various temperatures suitable for the characteristics of the material and dye composition (100) of the flocking fabric 200 to be dyed Adjustable with

The acid dye solution formed by mixing the acid dye and water as described above forms a dye composition (100) by mixing with synthetic glue, yuan, urea, the ratio of the acid dye solution 30-50% by weight, synthetic paint 45- 65 wt%, 0.5-2 wt% yuan, 3-7 wt% urea.

Explaining the reason for the composition ratio, the synthetic foil is 45-65% by weight of the mixed composition, by reacting with the acid dye solution to improve the dyeing of the locking fabric 200 and the acid dye to help the printing is carried out effectively The state serves as an intermediate medium, when the content is less than 45% by weight is insufficient to dye the acid dye to the locking fabric 200, the printing can not be made properly, if the content exceeds 65% by weight synthetic It is preferable to add 45 to 65% by weight of the synthetic paste because the burden is economically increased without showing a clear difference in the effect compared to the amount of the effective amount.

Foil serves as an intermediate medium that dyes the dye composition 100 to the locking fabric 200. The necessary properties include physical performance, that is, fluidity, viscosity safety, heating safety, dilution resistance, and catcher. The chemical performance includes the compatibility of the dye, chemical resistance, bacterial resistance, reduction resistance, and the like.

There are many different types of paints on the market, but their performances are different, and they have advantages and disadvantages. As a single paint cannot satisfy the characteristics required for printing, it is common to use two or three kinds of paints to compensate for the shortcomings. to be.

For reference, considerations in the selection of paints include: not impairing the color of the dye, having good homogeneity, not reducing, having thermal stability, having small bubbles of arc, small viscosity change, and bonding with fibers. It should be checked whether it is good and quick to dry, the skin layer after drying is soft, there is no cracking or peeling phenomenon caused by surface drying of the grass, solubility is good, and there is no toxicity.

Fish paste is classified into natural salt paste, semi-synthetic paste and synthetic paste, and natural paste is made of vegetable paste such as starch, natural rubber, vegetable protein, seaweed, animal paste such as animal protein, gelatin and glue, and mineral such as bentonite. Are classified as hory. Semisynthetic paints include fibrin derivatives, processed starches, processed natural rubbers, and synthetic paints include vinyl derivatives, acryl derivatives, synthetic rubbers, and the like.

The vinyl derivatives include polyvinyl alcohol (PVA), modified PVA, polyvinyl acetate, polyvinyl butyral resin, polyvinyl acrylate resin, and acrylic derivatives such as polymethacryl, polyacrylamide, and synthetic rubber butadiene. and urethane. In addition, there are alkyd resin and urea system.

In case of protection of polyester or nylon, PVA alone is insufficient in adhesiveness, and since the protection company is too hard, in order to solve this problem, salts of carboxyl groups formed by salts or saponification of organic acid copolymerized with acrylic acid and methacrylic acid ester as hydrophobic parts. An acrylic paint made of silver-soluble part is mainly used. In general, acrylic paints are the best among synthetic paints with different adhesion of coatings, forming coatings have elasticity and flexibility, and there is no problem of degrading and spiriting even after heat treatment. have.

The yuan is to improve the solubility between the dye composition 100, evenly dyed, and most of all the composition to improve the dyeability, preferably 0.5-2% by weight is mixed, less than 0.5% by weight, the effect does not appear, 2 If it exceeds the weight percent stimulation to the locking fabric 200 may cause fabric damage and printing defects, so mix 0.5-2% by weight of the yuan.

The urea (urea) is a 3-7% by weight of the composition is mixed, when the urea is mixed with the humectant action to increase the solubility of the dye composition 100 and increase the water content in the locking fabric 200, dye composition ( 100) Preferably, the acid dye, water, and synthetic paint mixtures do not have separate precipitates, their precipitation and foreign matters, and remain in a very stable state for a long time, and the sharpness of the printing of the flocking fabric 200 is increased. It helps to make progress clear and thick. In addition, when the ratio is mixed at less than 3% by weight, there is no apparent effect, and when the amount is mixed at more than 7% by weight, the effect is no longer increased.

Printing step (S20) is a step of cooling the dye composition 100 at room temperature, and performing printing in a pattern designed on the locking fabric 200, the method and apparatus is not limited to any one embodiment, known It is clear that various printing methods and printing devices can be used.

Drying step (S30) is a step of evaporating moisture by placing the printed locking fabric 200 in a cylinder of 70-100 ℃ for 30 ~ 90 seconds, the drying temperature is lower than 70 ℃, or shorter than 30 seconds In case of drying, if the drying does not proceed properly and the drying temperature exceeds 100 ° C. or the drying time exceeds 90 seconds, the work is delayed and the deformation and damage of the flocking fabric 200 and the dye composition 100 may occur. Since there is a 70 to 100 ℃ in the cylinder 300 is placed for 30 to 90 seconds to dry.

After the cylinder 300 in the drying step (S30) and dried after the locking fabric 200 is subjected to the heat-treatment step (S40) for dyeing by heat treatment for 20-35 minutes at a temperature of 90-110 ℃ complete printing. In the printing step (S20), the dye composition 100 is attached to the flocking fabric 200, the fixing composition is not fixed because the flocking fabric 200 and the dye composition (100) because the dye composition ( The drying step (S30) and the heating step (S40), which is a step of responsibly fixing 100 to the locking fabric 200, are essentially performed. The steaming step (S40) as described above is necessary in order to achieve the effect of the present invention, the method is preferably steamed through high temperature treatment, the temperature of 90-110 ℃ and 20-35 minutes conditions Can be processed under.

In addition, the steaming step (S40) is configured to spray the steam 400 of 1.5-2.5kgf / ㎡ to dry. The condition of the heating step is a value for more surely fixing the dye composition 100 to the flocking fabric 200, if the heating temperature does not reach 90 ℃, or if the time is less than 20 minutes, the dyeing is properly Since the water fall phenomenon of the dye composition (100) is not made, and if the heat treatment is performed for too long or the high temperature heating is performed, the economic loss and the damage of the locking fabric 200 may be increased. .

In a typical case, the purpose of washing the dyeing composition 100 of the portion in which the dyeing process is not properly proceeded by washing the locking fabric 200 after the heating process is completed, and the touch feeling, that is, the touch of the locking fabric 200 is improved. In order to achieve the purpose, such as a washing process must be carried out.

However, according to the printing method of the present invention locking locking fabric 200, after dissolving the acid dye in water, mixed with a synthetic foil to perform printing on the locking fabric 200, which has been inevitably implemented in the prior art It is useful to expect the ease of work and the creation of economic profits by drastically reducing the work process of printing by finishing printing in the drying step (S30) and the heating process (S40) without performing washing and dehydration process. This will occur.
