Description

DETAILED DESCRIPTION OF THE INVENTION The present invention applies markings with various designs to various colorless or colored fiber fabrics by a two-step printing process, and after drying, lightly treats the printed area with cold or hot water to print. This invention relates to a printed fiber fabric that can be washed off.

The conventional method of creating a sketch using natural Tsuyu grass green flowers has the disadvantage that it turns yellow over time, and the starch iodine method has the disadvantage that the sketch disappears over time.

In order to eliminate this drawback, if a method is adopted in which a water-soluble printing paste is directly printed onto the fiber fabric, coloring materials such as dyes and pigments will be fixed inside the fibers, and when washed off with water, the coloring materials will be completely removed from the fibers. It has the disadvantage that it does not fall off from inside and remains, leaving marking marks after drying.

Particularly in the case of dyes, they contaminate the fibers, and even in the case of dyes that have no affinity for various fiber materials, they tend to leave marking marks because they are fixed inside the fibers.Also, even in the case of pigments, inorganic substances, etc., fine particles are present. The more markings are left behind, the more likely a similar phenomenon will occur.

Previously, the present applicant filed a patent application for an invention relating to a novel printing method for marking various patterns that can be easily erased by washing on a textile fabric, which eliminates the above-mentioned drawbacks.

(Japanese Patent Application No. 52-111859) However, the present invention is technically completely different from the invention of the above-mentioned Japanese Patent Application No. 52-111859, and the inventors of the present invention have continued to conduct intensive research in order to eliminate the drawbacks of the conventional method. The present invention relates to a textile fabric produced by a two-stage printing method of a textile fabric that is completed as a result of the process. A pattern is printed using a water-soluble Ti glue, and then a natural or synthetic glue material with dyes or pigments added as a main component is used as a second step printing on the pattern of the first step printing area. Various patterns are marked by printing with a water-soluble printing paste, and after drying, the dye or pigment is washed off by lightly treating the printed area of the second stage with cold or hot water. The water-soluble natural starch used in the first stage printing of the present invention is a material that provides a printed fiber fabric with synthetic adhesives, such as polyvinyl alcohol glue, which has extremely sticky properties. When printed, it adheres to the fiber surface and forms a polyvinyl alcohol film on the fiber surface.

The polyvinyl alcohol used in this case has a polymerization degree of 1
A 15-20% aqueous solution in the range of 000-2000 is preferred.

A second stage water-soluble natural or synthetic glue material such as carboxymethyl cellulose (CMC) is then added with dyes or pigments.
The printing paste is printed so as to overlap the pattern of the polyvinyl alcohol printing area printed in the first stage.

As mentioned above, an extremely tough film is formed on the polyvinyl alcohol printed area immediately after printing, so even if the water-soluble CMC printing paste is printed in an overlapping manner, the dye or pigment will be blocked by this polyvinyl alcohol film. Adheres to the surface of polyvinyl alcohol without being stuck or contaminated inside the fiber.

The water-soluble printing paste used for the second-stage printing paste must not only be easily removed by water, but also have excellent adhesion to the first-stage printing paste.

In this case, it goes without saying that the combination of printing paste materials in the first and second stages is not limited to the combination of polyvinyl alcohol and CMC as described above.

Soluble starch, modified starch, sodium alginate, calcium alginate, ammonium alginate salt, methylcellulose, carboxymethylcellulose (CMC), and polyvinyl alcohol are used as the first-stage printing paste material, especially carboxymethylcellulose and polyvinyl alcohol 010-20% Aqueous solutions are preferred.

As the second-stage printing paste material, a 5 to 10% aqueous solution of soluble starch, modified starch, sodium alginate, calcium alginate, ammonium alginate salt, methyl cellulose, carboxymethyl cellulose, polyvinyl alcohol, etc. is suitable.

Although any dye can be used as the dye, for example, reactive dyes, acid dyes, vat dyes, vat dyes, etc. are suitable. Moreover, any inorganic or organic pigment can be used as the pigment.

In addition, colorless or colored flaky polyethylene, granulated or powdered synthetic resins coated with metal, talc, calcium carbonate, barium sulfate, fine particulate silica or glass powder, titanium dioxide ( TiOJ, metal powder, etc. can be used.

The printed fiber fabric created in this way with various patterns marked on it can be used for sashiko, sashiko, etc. without using any patterns, Chaco, Chaco paper, etc.
Embroidery and bainding (coloring) can be done, and after sashiko, embroidery, and bainting, unnecessary patterns can be lightly treated with cold or warm water to complete the desired design.

The above-mentioned textiles with sashiko, embroidery or painting can be used as loops, aprons, bags, cushion covers, etc.
It is sewn into skirts, vests, kookyongs, etc.

The printed fiber fabrics marked with the various patterns of the present invention have become difficult to fall off when washed with water due to changes over time.
The dyes or pigments do not discolor, and the desired design can be freely selected and used, and the remaining design can be easily washed off with cold or warm water after sashiko, embroidery, or painting. It has the advantage of not contaminating the intended product.

Next, a method for producing the printed fiber fabric of the present invention will be explained.

Example 1 (When using a 10% cotton bleached fabric) The 100% cotton bleached fabric was printed using the following A1 formulation as the first stage printing paste. The printed fiber fabric of the present invention was obtained by printing with step printing paste and drying.

The printed fiber fabric thus obtained was able to completely remove the design from the marking area by lightly washing with cold or hot water.

The addition of a small amount of methanol is intended to improve the drying properties of the printed film.

Example 2 (Using 100% polyester plain dyed fabric)
The first-stage printing paste having the following formulation A2 was used to print on the above polyester IOO% plain dyed fabric.

Then, the printed fiber fabric of the present invention was obtained by printing with a second-stage printing paste having the following B2 formulation and drying.The thus obtained printed fiber fabric of the present invention was washed with cold water or By lightly washing with warm water, we were able to completely remove the markings.

Using the following formulation as the first-stage printing paste, printing was carried out on a mixed printed fabric of 50 cm each of the above-mentioned polyester and cotton.

Next, printing was carried out using a second-stage printing paste having the following B3 formulation, followed by drying to obtain a printed fiber fabric in which the printing of the present invention was applied to a polyester/cotton=so:so printed fabric.

As in the case of Example 1, the thus obtained printed fiber fabric of the present invention was able to completely remove the design from the marking portion by mild washing with cold or hot water.
