DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a textile product having a buffering function for acidic or alkaline substances.

[0002]

2. Description of the Related Art Heretofore, the action of a chemical substance on a fiber product has been uniquely determined by the chemical composition of the fiber material itself, and has no buffer function except for protein-based fibers. Here, the buffer function refers to a function of reducing a change in hydrogen ion concentration that occurs when an acid or a base is added.

[0003] In today's living environment, acidic or alkaline substances are used abundantly, and it is true that there are many substances which, as a result of use, change to substances exhibiting acidic or alkaline properties. For example, sulfur oxides and nitrogen oxides generated by the burning of heavy oil in boilers and the like are released into the atmosphere. These are acidic substances, and if they dissolve in rainwater, they affect the living environment as so-called acid rain. Will come. Also, various chemical reactions occur in the human body, and sweat and urine are excreted as final products, and these also contain acidic or alkaline substances.

[0004] Even if such an acidic or alkaline substance has a low concentration in the initial aqueous solution state, its concentration increases with the evaporation of water, so that various problems occur. For example, if a low concentration aqueous sulfuric acid solution adheres to a cotton lab coat,
Holes in experimental clothing are a well-known phenomenon. This is because the dehydration reaction occurs between the cotton and the cotton due to an increase in the concentration of sulfuric acid, the cotton is carbonized, and the cotton falls off.

[0005] By the way, fiber products are used in a large amount in the living environment, and various types are available, but fiber materials having a buffering function for acidic or alkaline substances have been limited. Therefore, there has been almost no correspondence to acidic or alkaline substances due to the variety of textile products.

[0006] However, the increase of acidic or alkaline substances in the living environment surrounding us today has been necessitated to cope with this, but there has been a problem that there is hardly any textile product that can be coped with. . It is known that the optimal condition of the skin of the human body is maintained at pH 5 to 6, and in order to achieve this state, the textile is provided with a buffering function for acidic or alkaline substances. Would be preferred.

SUMMARY OF THE INVENTION
Conducted a study to provide a textile product having a buffering function with respect to acidic or alkaline substances. As a result, the present inventor considered the action of wool fibers in an aqueous solution of an acidic or alkaline substance, since they perform a buffering action on them. The amino group as the chemical composition of the wool, includes a carboxyl group, that each of the groups exhibiting a pH buffer function by ionizing acidic substance, a quaternary ammonium ion reacts with the alkaline material, the carboxyl ions In view of this , even if the fiber structure does not have such a buffer function,
Thus, the present inventors have found that a buffer function can be provided, and have reached the present invention.

That is, the present invention relates to a method for fabricating a fiber structure
The present invention relates to a textile product characterized by imparting a buffer function to an acidic or alkaline substance by attaching lead . In the present invention, zinc oxide, and the action of a base to acidic substances, it is a specific compound having an action of an acid for a basic substance.

A method for adhering zinc oxide to a fibrous structure;
The surface of the fibers that make up the fiber structure with zinc oxide
And the like. Specifically, zinc oxide
Using a solution containing, on a fibrous structure, a method of printing,
There are various methods such as a coating method, a padding method, and a spraying method. In this case, a drug such as a binder may be used in combination.

As the fiber structure used in the present invention, specifically, a single fiber alone, a twisted twist composed of one or more fibers,
Fabrics, knits, and non-woven fabrics using blended yarns and blended yarns are listed.
I can do it . In the case of a woven or knitted fabric, a cross-weaving or a cross-knitting may be used. The fibers constituting the fiber structure, specifically, cotton, and hemp, rayon, polynosic, cellulose fibers such as cupra, polyethylene terephthalate, polyester fibers such as polyethylene terephthalate and polybutylene terephthalate, acrylic fiber, acetate fiber or the like .
