Description

High Color And Fastness Textile Printing Process Of Aramid Fabrics

The present invention relates to a printing method of aramid knitted fabric, and more particularly, to a printing method using a catch-on dye by applying a swelling agent applied to aramid impregnation.

Aramid material is divided into meta-aramid and para-aramid, and because both materials have a dense molecular structure, dyeing is difficult because dyeing area is relatively small compared to other fiber materials. .

Therefore, many dyeing methods for aramid materials have been studied, and various research results such as dyeing by high temperature and high pressure, dyeing method using swelling agent and carrier, and dyeing method using supercritical are introduced.

However, the above method relates to soaking, and relatively little research has been conducted on printing. In the case of printing of aramid material, a printing process using a pigment is mainly used. Therefore, it is difficult to realize various colors of the final product due to the thickness of the pigment resin, and a problem of deterioration of touch feeling occurs.

On the other hand, Korean Patent Publication No. 1987-0011323 discloses a highly polar solvent consisting of dimethyl sulfoxide, NN-dimethyl acetamide, N-methyl-2-pyrrolidone and mixtures thereof, a printing paste thickener, water and A printing process for aramid fibers is disclosed which dries and cures the fabric after printing using a printing paste, optionally comprising at least one flame retardant.

In the prior art, it is difficult to completely remove the printing paste remaining in the washing process according to the use of the printing paste of high viscosity, so that the fabric touch feeling may be deteriorated, and there may be a problem of discoloration due to high temperature curing. In addition, the flame retardant is included in the printing paste to increase the water content of the printing material under general environmental conditions, which may cause problems such as poor physical properties, mold generation, and dye dyeing.

Therefore, in order to diversify the use of aramid fiber material, which is mainly applied as an industrial material, the dyeing process in the development of clothing material is an essential element and it is required to develop not only dyeing but also high color and high color printing method.

Therefore, the present invention is to provide a high color and high color printing method of flame retardant aramid material by solving the problems of the decrease in touch sensitivity and the decrease in color development, which are the problems of the prior art.

Therefore, according to the present invention, 2-10% by weight of alginate-based agent, 3-15% by weight of cellulose-based agent, 2-5% by weight of acid fixative, 1-20% by weight of wetting agent, 2-50% by weight of swelling agent, and catchon dye After preparing a color composition comprising 1 to 20% by weight and water as the remainder, the aramid knitted fabric is inlaid and pre-dried on aramid knitted fabric and cured at 130 ° C to 160 ° C for 1 to 2 minutes. Provided are a high color and high color fastening method of knitted fabrics.

Hereinafter, the present invention will be described in more detail.

The method of high color development and high color fastening of the aramid knitted fabric of the present invention is achieved by etching and curing a color-protective composition containing a scavenger, an acidic fixing agent, a wetting agent, a swelling agent, a dye, and water.

First, the color composition used as the printing foil is 2 to 10% by weight of alginate-based agent, 3 to 15% by weight of cellulose-based agent, 2 to 5% by weight of acid fixative, 1 to 20% by weight of humectant, 2 to 50% by weight of swelling agent, It is characterized by containing 1-20 weight% of catchon dyes, and water as remainder.

Alginate-based and cellulose-based agents are used for the lamination, and alginate-based may be sodium alginate and carboxymethyl cellulose may be used for the cellulose-based agent. When only alginate-based adhesives are used alone, the color development of the dyeing product is excellent, but the bleeding phenomenon may occur when heat-producing. In the case of using only cellulose-based adhesives alone, the color development is relatively weak, but there is no dye bleeding in the present invention. It is preferable to use the adhesive which mixed 2-10 weight% of protective agents, and 3-15 weight% of cellulose-based agents.

In addition, the color composition used in the present invention contains 2 to 5% by weight of acid fixative, 1 to 20% by weight of wetting agent, 2 to 50% by weight of swelling agent, 1 to 20% by weight of catchon dye, and the balance as well The acid fixing agent may be any one of citric acid, formic acid, and acetic acid, and in the process of evaporating and fixing the printing face and fabric, the pH of the catchon dye may be adjusted. The ionic bonding action, wetting agent uses urea (Urea), there is no significant change depending on the amount of wetting agent, but if the content is increased, the color strength of the dyeing sample can be seen to increase slightly. In particular, the present invention can provide a printing material that is vivid and improved in colorability, which is hard to see in printing materials using conventional bat dyes or pigments by using catch-on dyes for reasons of vivid color expression, washing, and durability against friction.

The swelling agent is any one of benzyl alcohol, butyl diglycol, butyl triglycol, 1-phenoxy-2-propanol, 2-ethoxybenzyl alcohol, dimethyl sulfoxide, N-methylpyrrolidone, dimethyl acetamide It can be used to facilitate dye penetration between the fiber molecular structure through the expansion of the aramid fibers, which is desirable to achieve the object of producing the color development enhancing printing of the present invention.

In the present invention, the color-homogeneous composition is cured after being inlaid and pre-dried on the aramid knitted fabric, and the inlaid is preferably screened to prevent spreading of the pattern and dye penetration. After printing, drying and curing are performed to fix the dye. Curing is performed at 130 ° C. to 160 ° C. for 1 to 2 minutes to perform heat transfer and fiber fixation of the dye included in the printing paste.

The printing method of the aramid knitted fabric according to the present invention has the effect of improving the color fastness, color development and touch by eliminating the problem of deterioration of color development in the conventional printing method and the deterioration of touch feeling generated when the pigment is applied.

The following examples are given as non-limiting examples of the printing method of the aramid knitted fabric of the present invention.

Example 1

2% by weight of alginate-based agent (sodium alginate), 3% by weight of cellulose-based agent (carboxymethyl cellulose), 2% by weight of acidic fixing agent, 10% by weight of humectant, 5% by weight of swelling agent, 1% by weight of cationic dye and remainder It was prepared to contain and mixed to prepare a color hosin composition, and then, after printing and pre-drying the meta-aramid knitted fabric by a screen method, curing at 130 ℃ 2 minutes to proceed with the fixing. Then, the remaining dye was removed by washing with water to complete printing, and the color intensity was measured using a CCM system. The color intensity did not show high color development below the light color level in the existing PET dispersion dyeing due to the low dye usage (1% by weight).

[Example 2]

Except for mixing 5% by weight of the catch-on dye in Example 1 was printed in the same manner as shown in Figure 3 a sample photograph.

Increasing the amount of dye used showed a higher color intensity than the printing material of Example 1.

[Example 3]

The printing process was performed in the same manner as in Example 2, and the fixing photograph was proceeded for 2 minutes at a curing temperature of 160 ° C. to show a sample photograph in FIG. 4.

Washing and frictional fastness of the samples subjected to the printing process by the method in Example 3, respectively, KS K 0430 A-1, KS K 0650; It carried out according to the test method of the crometer meter, and the result is shown in Table 1. Discoloration was less than that of Comparative Example 1 below, and the color development was good due to the small amount of dye dropped off when washed.

Comparative Example 1

Except for mixing the wetting agent 10% by weight, 5% by weight of the catch-on dye in Example 1 and the printing was carried out in the same manner except that the curing fixing temperature is set to 170 ℃ a sample photograph is shown in FIG. As the fixing temperature increased, the amount of dye dropped off at the time of washing was small, but the discoloration of the dye occurred at high temperature.
