Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a resin-adhered fiber product having excellent soft texture and durability.

[0002]

2. Description of the Related Art A pad dry method is used in which an ionic resin emulsion is immersed in a fiber product and dried and heat-treated. However, the adhesion form is not uniform, and the fibers do not adhere evenly to each fiber. They are attached in bundles and have a hard texture. In addition, such a form of attachment is liable to easily fall off due to a physical action, and thus has a disadvantage of lacking durability.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for producing a textile product having a soft texture and excellent durability, to which a resin is uniformly adhered.

[0004]

The present invention employs the following means to solve the above-mentioned problems. That is,
The method for producing a fiber product of the present invention comprises adding a resin emulsion stabilized by an ionic emulsifier, which is either one selected from anions and cations or a combination of the anion and a nonion, Using a resin treatment liquid formed by adding a substance having a point and having an emulsifying power, and immersing a fiber product in the resin treatment liquid,
The resin is adsorbed on the textile by treating in a bath at a temperature of 0 ° C.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention has been studied diligently for a method for producing a resin-adhered fiber product having a soft texture and excellent durability. In accordance with the ionicity of the emulsifier, during the immersion treatment, the pH of the liquid treatment bath composed of the resin treatment is adjusted, or a substance having the opposite ionicity to the ionicity of the emulsifier is added to the treatment bath. Surprisingly, the present inventors have sought to solve the above problems at once.

As the emulsifier in the present invention, ionic, anionic, cationic and nonionic can be used in combination with a general emulsifier for stabilizing a fiber processing agent, and anionic emulsifiers include fatty acids. Soaps, metal salts of alkyl sulfates, sodium alkyl benzene sulfonate, alkyl sulfates and the like can be used. As the cationic emulsifier, an alkylamine salt, an alkyltrimethylammonium salt, an alkyldimethylbenzylammonium salt, a quaternary ammonium salt, an alkylpyridium salt, an alkylimidazolinium salt and the like can be used. As nonionic cationic emulsifiers, polyoxyethylene alkyl ether type, polyoxyethylene alkyl ester type, sorbitan alkyl ester type,
A polyoxyethylene sorbitan alkyl ester type or the like can be used.

The content of such an emulsifier is preferably in the range of 0.001 to 0.1% by weight, more preferably 0.01 to 0.05% by weight in the resin treatment liquid. If the content of such an emulsifier is too small, unevenness and poor emulsifying properties will occur in the bath, and if it is too large, the fastness will decrease.

[0008] As a substance having a cloud point and having emulsifying power,
Nonyl phenyl, McCaw alcohol, lauryl alcohol, polyvinyl alcohol, and the like in which the degree of polymerization and the degree of saponification are adjusted can be used.

In the method for producing a textile product according to the present invention, a binder resin liquid can be used as a treating agent for textile processing for the purpose of adjusting texture and improving the adhesion durability of a hydrophobic substance. As such a resin, at least one selected from water-dispersed emulsified acrylate resin, polyurethane resin, silicone resin, melamine resin, polyester resin, polyamide resin and vinyl acetate resin is used. be able to.

The degree of polymerization of the resin is not particularly limited, but a low molecular weight resin is used, and when a certain temperature is reached, polymerization starts in a solution, becomes high molecular weight and adheres to fibers. Is done. At this time, a crosslinking agent may be used. The resin-attached fiber is taken out, dried, and preferably cured at a temperature of 120 to 180 ° C.

[0011] The material for the textile product to which the treatment agent for textile processing of the present invention is applied may be a natural fiber such as cotton, silk, hemp or wool, or a synthetic fiber such as nylon, polyester, polyacrylonitrile, polypropylene, rayon, Bemberg, acetate or the like. Fibers, semi-synthetic fibers, regenerated fibers or a mixture of these fibers can be used.
As the cloth made of such fibers, various applications such as knitted and woven fabrics made of the fibers alone, or mixed fiber cloths such as blended fibers, blended fibers and mixed knitted fabrics can be applied, and any structure and shape can be used. However, even if it is a thread-like thing, it is OK.

Next, as an example of the method for producing a fiber product of the present invention, a resin emulsion is added to the textile product 100 at a solid content of 0.5 to 20 parts (weight ratio). When a combination of an anion and a nonion or only an anion is used, an acidic substance is used to add a pH in the range of 2 to 6, or a cationic substance is added. When a combination of a cation and a nonion or only a cation is used,
The pH is added in the range of 8 to 10 using an alkaline substance, or an anionic substance is added.

Using a liquid dyeing machine or a bath with agitation, water is applied so that the bath ratio is 1: 5 to 100, and a textile fabric is put therein, and weighed in advance with stirring. Add the treating agent. When the temperature gradually rises thereafter, when the temperature reaches a certain point (cloud point), the white color of the emulsifier in the liquid disappears and the liquid becomes transparent. The treatment is carried out for about 5 to 30 minutes while keeping the temperature slightly higher than that temperature, and thereafter, the fabric is slowly cooled and the fiber product fabric is taken out and dried. The processing temperature must be a cloud point or higher. If the processing temperature is 40 ° C. or lower, the fibers rapidly adhere to fibers and become uneven, which is not preferable. 1
A temperature of 40 ° C. or higher is not preferable because of physical properties such as color fastness and restrictions on equipment. A more preferable temperature range is 60 to 100.
