Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to natural, artificial, and synthetic fibers and their 5FA spun,
All kinds of textile products made by interlacing, intertwisting, and texturing, as well as web-like processed materials such as paper and non-woven fabrics, are generally flexible, so transportation, cutting, sewing, shaping, etc. are necessary for commercialization. Concerning hardening agents and hardening methods for temporary hardening in cases where it is easy to handle, whether it is processed or hardened, and it leads to improved productivity and quality of the final product. It is something.

The curing agent used in the process of the present invention is used in the subsequent drying step 11! In order to make it easier to handle, etc., it can be dissolved in either water or organic solvents, and the hardening agent may discolor or fade, reduce the strength, or cause the hardening agent to adhere to the treated cloth in the form of a scum. It must be free of

The curing agents that can be used alone in the present invention include polyvinylpyrrolidone, polyvinyl alcohol, polyacrylic l'l
Copolymers include copolymers of acrylic acid and methacrylic acid, copolymers of acrylic acid and acrylic esters, copolymers of acrylic acid and acrylamide, etc. polymers or eight derivatives thereof, styrene and maleic anhydride copolymers, vinyl acetate maleic anhydride copolymers,
Alternatively, these 8-wire Xi conductors, copolymers of polyvinylpyrrolitin and vinyl acetate, and the like are water-soluble and organic solvent-soluble substances. On the other hand, mM agents include monohydric alcohols such as methyl alcohol, edyl alcohol, n-propyl alcohol, isopropyl alcohol, n-butyl alcohol, isoprol alcohol, hensyl alcohol, and thymol, and mono-, tri-, and triethylene dilicols. , polyhydric alcohols such as propylene glycol+i, glycerin, and resorcinol; ketones such as acetoxy, methyl ethyl ketone, and cyclohexane; ethers or esters having hydroxyl groups such as methyl ethyl cellosolve, and ethyl cellosol;
Ethyl ether, inpropyl ether, tetrahedral ether,
Various solvents such as ethers such as Lofuran, aromatic hydrocarbons such as Hensen, toluene, and xylene, halogenated hydrocarbons such as chloroform, carbon tetrachloride, hardened ethylene, trichloroethane, trichloroethylene, and tetrachloroethylene, etc., singly or in combination. It can be used as

The above-mentioned curing agent is used as above-mentioned 4i! Cloth dissolved in a solvent or water and generally finished with an ath-grade finish and made into a product 5
' or apply it to the wedge by spraying according to the degree of curing required, and complete the curing process by passing it through an infrared dryer or the like.

In addition, in order to complete the desired processing and return the treated fabric to its original soft state, it generally requires treatment with water or dry cleaning equipment, or when it does not need to be completely removed. Light <l: It can be removed by applying a cloth or applying a steam press using a cloth.

In addition, the chestnut agent used as a copolymer to improve adhesiveness is a polyurethane resin, an epoxy resin, an acrylic ester resin, or the like.

Example 1 50% of vinyl pyrrolitone and vinyl acetate copolymer dissolved in ethyl alcohol was applied to a reduced weight georgette (90q/m cloth dyed product) of 100% polyester processed yarn using a Hunt sprayer. By applying a high temperature (wet state) and drying it with a 3-unit infrared dryer, a cured cloth is obtained which has 852 better physical properties and is easier to handle than an untreated cloth.

Physical properties due to hardening treatment Jl + J + Friendship Example 2 2% aqueous solution of a hardening agent emulsified with 500 parts of 50% isopropyl alcohol of a copolymer of acrylic acid and acrylic acid ester, 50 parts of an anionic thread emulsifier, and 450 parts of water. 1 in hot water
Twenty pieces of cotton jersey are soaked, thoroughly dehydrated, passed through a dryer to harden, and then cut and sewn into men's shirts.

Generally, fine count cotton jersey 1'! Although it is soft and unstable in shape, it is difficult to handle, but this hardening process makes it easier to handle, and unattended sewing using Rohot etc. is also possible.

Note that M hardness easily returns to its original softness with +sm dry cleaning.

Claims (1)

[Claims] In order to facilitate the processing of textiles, knits, nonwovens, paper, and other web-like workpieces such as transporting, cutting, sewing, and shaping, the present invention hardens to a desired hardness and returns to its original state after processing is completed. This relates to a special processing method that allows the user to return to a state close to the original state. In particular, the present invention is characterized in that, for example, polyvinylpyrrolidone is mixed with a substance soluble in water and organic solvents, and an adhesive substance such as hinyl acetate is mixed in arbitrary proportions, and the structure of the material and workpiece is The mixed treatment agent is dissolved in water, alcohol, or other organic solvent, and the spray method vIi is characterized by applying it to the object to be treated by dipping and then drying it at a temperature of 100°C or less. The desired hardened product can be obtained.
