JPS5911711B2 - Anti-mold and anti-static processing method for textile products - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for preventing lateral mold and static electricity on textile products.
A processing method that provides anti-mold and anti-static properties that are highly durable, safe and harmless to the human body? It is on offer.

In order to protect textile materials from microorganisms such as mold, it is necessary to incorporate a substance with sterilizing power into the fibers.

It is desirable that this substance is retained within the textile and remains intact throughout the use of the treated product, even after repeated washing and cleaning.

The most commonly used compounds are organic mercury compounds, organic tin compounds, organic chlorine compounds, phenolic compounds, and the like.

However, recently, the use of organometallic compounds has been restricted due to reasons such as sanitary safety, and there has been a demand for new compounds to be developed as fungicides.

For example, as a new anti-mold disinfectant, a cationic surfactant is being used as a disinfectant in hospitals and the like in place of cresol soap.

Among them, quaternary ammonium salts, which are one of the cationic surfactants, have relatively low toxicity to the human body and are used for sterilization and disinfection, but they are also used for antiseptic and antiseptic purposes.
It has also come to be used as a fungicide and sterilizer.

The quaternary ammonium compound contained in the alkoxysilane group is chemically adsorbed on cotton or polyester, and has wash resistance, so it can be used for anti-mold treatment of textiles.

That is, tri-methoxy-silyl-propyl-dimethyl-alkyl-ammonium-chloride (where R(
When a compound such as an alkyl group (with a C number of 6 to 22) is dispersed in water, the methoxy group undergoes hydrolysis, and at the same time, the fiber surface and the oxygen atom form a covalent bond.
This is to form a durable fourth film ammonium salt film.

However, according to experiments conducted by the present inventors, textile products treated with these alkoxysilane compounds alone have the disadvantage of causing skin damage to the human body.

As a result of extensive research, the present inventors have found that by adding a fatty acid with bactericidal properties to the above compound and forming a kind of complex with a cationic activator such as a quaternary ammonium salt, the original bactericidal property and preventive properties can be improved. Succeeded in eliminating skin disorders without losing its fungal properties, and also having an antistatic effect.
The invention has been completed.

That is, the gist of the present invention is that tri-alkoxysilyl propyl dimethyl alkyl ammonium chloride (however, alkyl 4 is Ci6-22) and C11O-1
The present invention relates to a method for preventing mold and static electricity on textile products, which comprises dispersing the surfactant in water using a complex surfactant with monoethylene fatty acid (No. 8) and treating the textile product with vaginal fluid.

It is important that the fatty acid used in the present invention is a C10-18 monoethylene fatty acid.

Monoethylene fatty acids such as undecylenic acid in this range have a bactericidal effect against Durum-positive bacteria, Durum-negative bacteria, filamentous fungi, etc., and are synergistic when complexed with alkoxysilyl quaternary ammonium salts. It can be effective.

It has been confirmed in many literatures that these cationic surfactants and anionic surfactants form a complex.

However, in order to disperse fatty acids in water, it is important to emulsify and disperse them using a surfactant such as a nonionic surfactant that does not cause a chemical reaction with the quaternary ammonium salt.

In the present invention, tri-alcoquine, silyl,
Mix 60-80% propyl dimethyl alkyl ammonium chloride (same weight), 10-20% monoethylene fatty acid, and 10-20% nonionic surfactant, and add the mixture to water at a concentration of 1%. Immediately immerse the textile product to be treated in this diluted dispersion solution for about 1~
After being left for 2 hours to be sufficiently adsorbed onto the fiber surface, it is dehydrated and dried.

This provides a durable surface treatment with excellent mildew and antistatic properties for textile products.

In addition, as a treatment means, in addition to dipping, impregnation, coating, direct addition, etc. can be determined and implemented as necessary.

Hereinafter, typical examples will be shown and explained.

Disperse 10 g of the above mixture in 1 t of water, add 4 ml of cotton
A treated fabric was obtained by soaking 100 g of a blended fabric of 0.0 polyester 60, leaving it for 60 minutes at room temperature, dehydrating it, and drying it (100°C).

・Mold resistance test on treated fabric (J l5-Z-291
1. Mold resistance test method 6.2.1. The results of the dry method) and chargeability test (using a rotary static tester) are shown in the table below.

As is clear from the above table, the anti-mold effect, washout resistance and antistatic effect of the present invention are remarkable.

The following test was conducted regarding skin disorders.

Using 100% cotton socks, use 2 weights of each of Samples A and B relative to the weight of the socks to make an aqueous solution at a bath ratio of 1:2.
After immersion treatment at 0.50°C for 30 minutes, it was dehydrated at a squeezing rate of 80 and dried at 80°C for 30 minutes to prepare a sample for skin damage test.

The test was conducted on 20 subjects using the skin patch test method of the Japan Industrial Skin Hygiene Association.

The results are shown in the table below, and it can be seen that the product does not cause any skin damage and is safe and harmless.

As described above, the processing method of the present invention not only exhibits an antistatic effect and sufficient sterilizing effect against microorganisms on textile products, but also provides hygienic processed products that are imparted with wash-resistant and mildew-resistant properties. It also solves the problem of skin disorders and is extremely useful as a processing method for textile products.
