Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a method for treating textile products, and more specifically, to the color fastness and brittleness of textile products mainly made of polyamide dyed with acid dyes or metal-containing dyes. Concerning throughput methods to improve prevention.

BACKGROUND OF THE INVENTION Due to its durability, polyamide fibers are one of the most popular non-clothing products. Among them, hot dyes and dyestuffs have a problem with IQ (high 5) of color fastness due to heat.

The present inventors have arrived at the present invention as a result of intensive studies aimed at solving the above problems.

Purpose of the Invention The purpose of the present invention is to provide polyamide fibers dyed with acid dyes or metal-containing dyes. Preventing embrittlement and improving color fastness of mainly textile products? The purpose is to provide a processing method that results in

Components of the Invention The present invention involves dyeing textile products made of polyamide fibers or mixed fibers of polyamide fibers and other fibers with acid dyes or metal-containing dyes, and then dyeing them with cal/(cyto) photooxidants and hydrazine-based dyes. Provided is a method for treating textile products, characterized in that the textile product is treated with at least one type of acid oxidation prevention agent selected from the group consisting of acid oxidation prevention agent 1 ≧.

Detailed explanation of the structure of the invention In Taichomei, textile products include HoIJ 7 Mi) textile products consisting of fibers or mixed fibers of these fibers and other fibers;
In particular, it is a hot carpet made of a pile yarn made of the fibers or the mixed fibers, and a base fabric made of a nonwoven fabric mainly composed of polyester fibers.

Examples of the antioxidant used in the present invention include carbazide-based antioxidants and hydrazine-based acid oxidation inhibitors.

1.6-hexamethylenebis(N,N-dimethylsemicarbazide) and acetoneteose are carbazone,
Examples of hydrazine-based acid hydrazide inhibitors include adipic acid hydrazide, sebacic acid hydrazide, and inphthalic acid hydrazide.

The antioxidant may be dissolved in water, or if it is insoluble in water, it may be dissolved in an organic solvent such as benzene, toluene, or xylene to make it liquid-resistant, or it may be mixed with a surfactant having emulsifying power, preferably a phase-resistant one. It may be used as a dispersion by dispersing it in water using a nonionic surfactant.

The antioxidant may be applied to the fibers in an amount of 0.1 to 1 [by weight], and a usual dipping method or pad method can be used as the treatment method.

When treated according to the method of the present invention, thermal acid decomposition of polyamide fibers and dyes is prevented, thus improving fiber strength and colorfastness, resulting in durable storm-quality textile products.

EXAMPLES The present invention will be fully explained with reference to examples below. Parts in f4Lflll and parts by weight are shown respectively.

Example 1 (Example of Preparation of Antioxidant Aqueous Solution) 1.100 parts of 6-hexamethylenebis(N,N-dimethylsemicarbazide) are stirred and dissolved in 900 parts of water (referred to as antioxidant A).

Example 2 (Example of preparing an aqueous solution of acid hydration inhibitor) 100 parts of adipic acid dihydrazide? water? Stir and dissolve in oos (referred to as antioxidant B).

Example 3 (Performance Test Example) A performance test was conducted as follows using the water M product of the antioxidant described above. The results are shown in Tables 1 and 2.

a) Test fabric A hot curved fabric in which the pile yarn is a boliad fiber and the base fabric is a polyester fiber is used, which has been dyed as shown below.
