Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to woven, knitted, interwoven, interwoven,
The present invention relates to a novel method for treating shrinkage by transfer, the purpose of which is to extremely effectively apply an unprecedented shrinkage pattern to a blended fabric.

Conventionally, many mechanical or physicochemical methods have been known as shrink processing methods for imparting irregularities in appearance and feel to cloth, and these treatments are usually referred to as crimp processing, ripple processing, etc. , the result is a similar product to soccer fabric.

Embossing, which compresses cloth by heating and pressurizing it with a patterned mold, also provides a similar effect.

However, during the above-mentioned shrinking process, physicochemical processes are widely used because mechanical processes have drawbacks such as unclear pattern outlines, unnecessary gloss, and high equipment costs.

This physicochemical processing method involves creating a printing paste containing a drug that has a swelling or dissolving effect on the fibers that make up the target fabric, printing the printing paste in a pattern on the fabric, and applying tension or non-stretching. If necessary, heat treatment is performed under tension, or, contrary to this method, a material that blocks the influence of the chemical is printed on the cloth in a pattern, and then the cloth is treated with the chemical.

These physicochemical processing methods have the advantage that they can be carried out at low cost by simply selecting chemicals depending on the various fibers that make up the fabric, do not require special equipment, and can be colored at the same time.

However, cloth, including woven and knitted fabrics, has an extremely uneven surface structure and is porous, so the printing paste used in the above-mentioned physicochemical processing method must be uniformly and effectively printed on the cloth in large quantities. It's more difficult than you might imagine.

In addition, the paste, other ingredients, and all impurities that make up the printing paste containing the drug remain firmly on the cloth, which impairs the tactile feel of most processed products and makes the printed color unclear. It is the cause of

Therefore, physicochemical processing methods are limited to processing plain woven fabrics such as taffeta fabrics, dechine fabrics, etc., and georgette fabrics,
It is difficult to apply it to knits, etc.

In order to fundamentally improve the shortcomings of such conventional methods, the present inventor has conducted various researches, and as a result, formed an arbitrary pattern on a sheet-like carrier using printing ink containing a drug that swells or dissolves the fibers of the target fabric. Using the transfer paper obtained, the transfer paper is polymerized onto the target fabric, and then heat and pressure are applied to calculate the difference in shrinkage of each part of the fabric that comes into contact with the patterned and non-patterned areas of the transfer paper. By revealing the uneven pattern, various types of fabrics, including woven and knitted fabrics, regardless of their type, can have an extremely sharp and sharp shrinkage state, and have no negative effect on color, and have a noticeably softer texture. With this discovery, the present invention was completed.

Next, the configuration of the present invention will be explained in detail.

Examples of the sheet-like carrier for creating the transfer paper used in the present invention include cellulose paper, synthetic paper, cellophane, synthetic resin film, nonwoven fabric, and composite materials, and they also have water permeability and gas permeability. It also includes those that have been treated to improve their solvent resistance.

Next, the agents that swell or dissolve fibers are generally common to synthetic fibers such as polyester fibers, polyamide fibers, polyacrylic fibers, and acetic acid cellulose ester fibers, such as β-naphthol, carbolic acid, metacresol, resorcinol, Kiphenols such as orthophenylphenol and their alkali metal salts; alcohols such as Handel alcohol, ferethyl alcohol, glycerin, and polyethylene glycol; ethers such as β-naphthol methyl ether, phenetol, and polyoxyethylene hydrocarbon ether; Ketones such as benzophenone and cyclohexanone, organic acids such as salicylic acid, naphthalenecarboxylic acid and benzoic acid, phenyl salicylate, methyl salicylate, glyceride benzoate, tricresyl phosphate, dibutyl terephthalate, polyoxyethylene fatty acid ester esters such as valatoluenesulfoamite, stearylamide, acidamides such as polyoxyethylene organic acid amide, hydrocarbons and their derivatives such as methylnaphthalene, methylpendelamine, trichlorobenzene, and valaanisidine, and ethylene carbonate and dimethyl. Examples include sulfoxide.

On the other hand, natural fibers such as cotton, wool, silk, rayon, and polynosic include thiourea, rhodanammonium, methyl cellosolve, urea, triethanolamine, caustic soda,
Examples include paraform.

The above agents are used alone or in combination depending on the type of fiber of the target fabric, but among these, those that are liquid at room temperature can be used for emulsification, microencapsulation, absorption into adsorbent substances, or high melting point compounds. Those that are solid at room temperature constitute printing inks in the form of fine powder, dispersion, or solution, respectively.

The required amount of the agent varies depending on the type of fiber, printing method, thermal conditions during shrinkage processing, etc., but in general, it is 20 to 65% by weight for the gravure method, and 15 to 50% by weight for the roller method.
, 10-40 for flat automatic screen method
In the case of the band screen method, approximately 10 to 30% by weight is considered to be appropriate.

However, these values are not particularly limited and are determined depending on the desired contraction effect and the type of drug.

The printing ink in the present invention consists of the above-mentioned chemicals and various auxiliary agents added during normal textile printing and printing.

For example, organic solvents, water, surfactants, protective colloids, extender pigments, adsorbents, antioxidants, reduction inhibitors, chelating agents, and others are appropriately blended.

In addition to these, the printing ink can also contain fluorescent brighteners, dyes, pigments, reducing agents, oxidizing agents, etc., which can cause whitening, coloring, and coloring at the same time as shrinkage. One of the features of the present invention is that discharge printing is also possible.

In the present invention, printing ink is printed on the sheet-like button body using a normal printing method, but this printing operation is not necessary because the object is a sheet-like body with high smoothness, unlike cloth. It has the advantage of being able to uniformly, evenly, and supply a large amount of the drug.

After the printing ink is formed into any desired pattern on a sheet-like carrier, it is preferably dried, and if necessary, it is heated slightly to remove unnecessary volatile substances, etc. A transfer paper for use is obtained.

Next, the transfer paper is polymerized and brought into contact with the drug-affected cloth on the transfer paper, and heated and pressurized, e.g.
Treatment is performed at 0°C, 50 to 250 f//crA, or left unstressed for several hours, and if necessary, water washing, reduction cleaning, etc. are performed.

In this way, the cloth shrinks in the portions that contact the patterned portions of the transfer paper, while the portions that contact the non-patterned portions of the transfer paper remain intact.

Therefore, a clear wrinkled pattern is easily revealed, and the material has an extremely soft texture.

Next, the effects of the present invention will be listed.

(1) According to the present invention, it is possible to very easily create a sharp crimp pattern on georgette woven fabrics and tricot knitted fabrics, which have not been possible in the past, and the industrial applicability of this point is great; In addition, compared to conventional crimp processing methods, the fineness of the pattern and the dimensional stability are outstanding.

(2) According to the present invention, only the agent that has the property of swelling or dissolving fabric fibers is transferred to the fabric, so there is no harmful residue or shrinkage blocker (for example, glue film) on the fabric, and therefore it is extremely effective. You can get a very clear pattern with a surprisingly soft texture.

(3) According to the present invention, the color of the already-attached wrapping cloth does not become unclear.

(4) It is possible to simultaneously color the transfer paper used in the present invention by forming a pattern with a sublimable dye or the like in advance, or by adding a pigment to the printing ink of the present invention and performing a shrinkage treatment. In addition, it can be used in combination with resist dyeing materials and discharge printing materials to create a wide variety of changes.

(5) According to the present invention, it is possible to store transfer paper in a transferable state at all times, and it is possible to perform arbitrary processing on expensive cloth at any time.

Next, examples will be shown.

Example 1 Benzoic acid pendel 20 parts by weight (hereinafter, parts by weight is abbreviated as parts), β-naphthol 20 parts, Ethocel 5TD-100 (
A mixture consisting of 5 parts of product name), 1 part of orbene, and 54 parts of isobutyl alcohol was finely milled in a colloid mill to make a printing ink for shrinkage.
Prepare a blue printing ink consisting of 2 parts (trade name, dispersible dye), 15 parts of Ethocel 5TD-7 (trade name), and 83 parts of isobutyl alcohol, and add pure white roll paper (65f?/rr).
1) On top of this, the above-mentioned printing ink for chichichi was printed at 10 mm intervals using a horizontal striped gravure plate (451,100μ) with a thickness of 3mm (printing speed 25m10), dried through a hot air dryer, and then pulled. Continuing, apply the above-mentioned blue printing ink to a horizontal striped gravure plate (15011
25μ) (at constant speed) and dried to obtain a transfer paper.

Next, after polymerizing the transfer paper with polyester georgette cloth (transfer paper is 1200 mm wide, cloth is 1 yard wide)
, 200℃ x 30 seconds with a cylinder type thermal transfer machine, 150
After the transfer paper was peeled off by heating and pressurizing the cloth using a vacuum cleaner/crrt, the treated cloth was washed with water, subjected to reduction cleaning, and dried.

In this way, a wrinkled polyester georgette fabric with sharp horizontal stripes was obtained, in which recesses shrinking to about 2 mm in diameter and blue colors of the same diameter were observed alternately at about 5 square intervals.

The fabric had an overall shrinkage rate of 95% in the transverse direction and 86% in the longitudinal direction, and had an extremely soft feel.

As a comparative example, gravure printing was carried out without using the transfer paper used in this example, and with a crimp printing paste containing the same chemicals as the printing ink of this example, which is based on a normal water-soluble sizing agent instead of isobutyl alcohol and ethocel. However, due to the porosity of the georgette fabric, the printing paste hardly adheres to the surface of the printing plate, and penetrates and is taken to the plate cylinder surface. No shrinkage effect was observed, and the appearance resembled contamination with light brown zigzag horizontal stripes, and the difference in effect from this example was clear.

Example 2 A shrink printing ink consisting of 15 parts of ethylene carbonate, 15 parts of resorcinol, 20 parts of activated clay, 2 parts of Demol N (trade name), 8 parts of Mapro Gum NP (trade name) and 40 parts of water was applied to unbleached kraft roll paper. (65P/m), print lines with a diameter of 5 in a diamond-shaped lattice pattern at equal intervals using a rotary screen nickel plate (60 mesh) with a 20mm margin.
It was dried at 60°C to obtain a transfer paper.

Next, it was superimposed on a red colored acrylic knit cloth and heated and pressurized at 180° C. for 60 seconds at 200 f/cA using an open/close type thermal transfer machine, and then the transfer paper was removed, and the cloth was washed with water and dried.

In this way, a red acrylic knit printed fabric was obtained in which a crimp pattern of a diamond-shaped lattice consisting of concave lines with a diameter of 3 mm was clearly visible, and the texture was extremely soft.

For comparison, when the printing ink used in this example was printed directly on the cloth, it adhered in a very uneven zigzag pattern, and when the cloth was similarly heat-treated, it was printed in an uneven diamond pattern. It becomes a wrinkled pattern, and the wrinkled patterned area of the face is noticeably whitened.
It could not be removed with any detergent, and the texture of the cloth was extremely rough and hard, and was completely inferior to that of this example.

Example 3 20 parts of metacresol, 10 parts of urea, 20 parts of diatomaceous earth, 13 parts of naphka crystal gum, Dixsol (trade name)
5 parts and 30 parts of water were emulsified, and further, acidrhodamine B
(Product name) 1 part diethylene glycol to create a pink chichimi printing ink, unbleached kraft roll paper (
65? /m2') using a roller plate (20 diagonal lines) having a vertical stripe pattern with a diameter of 5 mm and an interval of 10 intervals, and dried to prepare a transfer paper.

Next, the transfer paper and nylon taffeta (6.6 nylon) cloth were overlapped and heated at 190℃ x 45cm using a cylinder type transfer machine.
After heating and pressurizing at 50 fl/crA for 2 seconds,
The transfer paper was removed, and the cloth was washed, soaped, and dried.

In this way, a sharp nylon taffeta crimp fabric was obtained in which the concave linear pattern, which had shrunk to four diameters, was colored bright pink.

The texture of the processed fabric was extremely soft.

Note that when the transfer paper was prepared, it was not dried and was subsequently heat-treated in contact with the nylon cloth, which shrunk to a diameter of 3 mm, but the texture tended to be slightly inferior.

As a comparative example, when nylon taffeta was directly treated in the same manner using the printing ink of the present invention, the wrinkled pattern was good, but a gray-red vertical striped pattern was formed, and the texture was extremely rough and hard.

Example 4 40 parts of β-naphthol methyl ether, Neugen EA-1
Finely disperse 4 parts of 90 (trade name) and 56 parts of water in a ball mill, and prepare 50 parts of the dispersion and 1 part of Superlite SZ (trade name).
A printing ink with shrinkage and discharge properties was prepared by blending 0 parts of Yuzen photo glue and 40 parts of Yuzen photographic glue. A transfer paper was obtained by printing using an argon type screen printing machine and air drying.

Next, the transfer paper was layered with a polyester/cotton blend (65:35) broad cloth colored with a light blue accessible dye, and ironed at 185°C for 60 seconds at 250°C. /c4
After the treatment, the transfer paper was removed, and the cloth was washed with water and dried.

In this way, a sharply wrinkled polyester/cotton printed fabric was obtained in which a concave polka dot pattern with a diameter of 7m7n appeared in white on the pale blue dyed surface, and was also extremely soft to the touch.

Reference Example 1 When the transfer paper of the present invention is a roll paper, it shows almost the same effect when carried out under the same conditions after being rolled up and stored, and after the sunset.
In addition, the wrinkled pattern of each Example was good in normal washing, dry cleaning, and light resistance.
