Embodiment 1

[0017] Use 6 grams of commercially available iron phthalocyanine to evenly disperse in 1000 grams of 15% polyvinyl alcohol aqueous solution by weight, then defoam, and extrude the slurry into a 50°C Glauber's salt coagulation bath on a small spinning machine through a spinneret hole It is coagulated into silk, then wet-heat stretched in Glauber's salt liquid at 90°C, then dry-heat stretched, acetalized, washed, oiled, and dried to obtain vinylon fiber containing iron phthalocyanine. The ammonia elimination rate of the fiber is 77%, and the hydrogen sulfide elimination rate is above 90%.

[0018] Detection method: Put 2 grams of fiber containing the catalyst in a 10-liter plexiglass sealed box with a latex injection window, fill it with odorless fresh air and seal it, inject ammonia or vulcanization through the latex window with a syringe Hydrogen gas so that its concentration is around 100 PPM. Analyze the concentration of ammonia or hydrogen sulfide by gas chromatography. A...

Embodiment 2

[0022] Disperse 2.5 grams of manganese porphyrin in 1000 grams of polyacrylonitrile by weight in 14% sodium thiocyanate aqueous solution (the sodium thiocyanate in sodium thiocyanate aqueous solution is 50% by weight), static defoaming , squeeze the solution into 10% sodium thiocyanate aqueous solution at 10°C through the spinneret hole to solidify into a precursor, then pre-stretch through the second coagulation bath, the coagulation bath is 3% sodium thiocyanate aqueous solution, and the bath temperature is 50°C. Then it is stretched by steam, the stretching temperature is 100°C, then washed with water, oiled and dried. The dried fibers are crimped at 85° C., heat-set at 130° C., oiled again, and dried at 120° C. to obtain acrylic fibers containing manganese porphyrin. The ammonia elimination rate of the cloth is 65%, and the hydrogen sulfide elimination rate is 84%.

Embodiment 3

[0024] Dissolve 1000 grams of 15.4% polyvinyl alcohol aqueous solution with 4.5 grams of tetracarboxyphthalocyanine cobalt sodium salt, and extrude the slurry into a 52° C. mirabilite coagulation bath on a small spinning machine to coagulate into silk. Then wet heat stretching in Glauber's salt solution at 88°C, dry heat stretching at 210°C, acetalization, water washing, oiling, and drying to obtain vinylon fibers containing cobalt phthalocyanine and covalently bonded fiber macromolecules. The ammonia elimination rate of the fiber is 73%, and the hydrogen sulfide elimination rate is over 90%.

Abstract

The invention provides a chemical fiber containing organ-metallic catalyst. The weight ratio of the organ-metallic catalyst and the macromolecular compound which is nitrile, cellulose fiber, is (0.5-8): (92-99.5). The organ-metallic catalyst is the organic compound of the Fe, cobalt or manganese. a) phthalocyanine Fe, cobalt or manganese; b) porphyrin Fe, cobalt or manganese; c)porphin Fe, cobalt or manganese. The organ-metallic catalyst is dissolved in the spinning slurry, so to get the fibre by the wet spinning technology. The fiber is deodorant.

Description

technical field [0001] The present invention relates to a chemical fiber containing an organometallic catalyst, a manufacturing method and an application thereof. Background technique [0002] With the continuous improvement of people's living standards, people have higher and higher requirements for clothing and home textiles in terms of aesthetics, comfort, and hygiene. It is hoped that some textiles can have the effect of removing odor. People have done a lot of work on this side. At present, basically some just add antibacterial substances in the process of chemical fiber production, and some add antibacterial substances in the method of finishing, so that fibers or fabrics have bactericidal and deodorizing effects. Relevant reports on bactericidal and deodorant effects include: Xiao Yaonan, Zeng Hanmin's research progress on antibacterial and deodorant functional fibers (2): Preparation, Materials Science and Engineering, 2001, 2, 80-88; Huang Hansheng, Recent developm...
