Embodiment 1

[0015] Evenly disperse 100 grams of commercially available iron phthalocyanine in 1000 grams of polypropylene slices, melt and push the polypropylene slices mixed with iron phthalocyanine through the screw extruder through the filter device and distribution plate in the spinning assembly, and finally pass through The spinneret hole is extruded to the cooling air channel, cooled and shaped, wound, and the wound fiber is stretched and shaped. Polypropylene fiber containing iron phthalocyanine was obtained. The ammonia elimination rate of the fiber is 77%, and the hydrogen sulfide elimination rate is above 90%.

[0016] 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...

Embodiment 2

[0020] Use 15 grams of porphyrin manganese to evenly disperse in 1000 grams of polypropylene slices, and the polyamide slices mixed with iron phthalocyanine are melted and pushed through the screw extruder and passed through the filter device and distribution plate in the spinning assembly, and finally sprayed. The wire hole is extruded to the cooling air channel, cooled and formed, and wound. The wound fiber is stretched and shaped. Polypropylene fiber containing iron phthalocyanine was obtained. The ammonia elimination rate of the fiber is 65%, and the hydrogen sulfide elimination rate is above 84%.

Embodiment 3

[0022] Use 27 grams of cobalt tetracarboxyphthalocyanine cobalt sodium salt to evenly disperse in 1000 grams of polypropylene slices, and the polypropylene slices mixed with iron phthalocyanine are melted by a screw extruder and pushed through the filter device and distribution plate in the spinning assembly, etc. , and finally extruded through the spinneret hole to the cooling air duct, cooled and formed, and wound. The wound fiber is stretched and shaped. Polypropylene fiber containing iron phthalocyanine was obtained. The ammonia elimination rate of the fiber is 73%, and the hydrogen sulfide elimination rate is over 90%.

Abstract

The invention discloses a chemical fiber within organic metal catalyst, wherein the weight ratio of organic metal catalyst and spinning macromolecular compound is between 1: 10 and 1: 200; the organic metal catalyst contains the compound of iron, cobalt, manganese. The making method of the chemical fiber comprises the following steps: (1) dispersing the organic metal catalyst into the microtome section of spinning macromolecular compound uniformly at the ratio ranged from 1: 10 to 1: 200; (2) producing the fiber through conventional molten method spinning technique. The invention concludes the following advantages: good odour-away effect, small investigation, former fiber production equipment without changing, continual industrialized production.

Description

technical field [0001] The invention relates to a functional fiber and a manufacturing method thereof, in particular to a chemical fiber containing an organometallic catalyst and a manufacturing method 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 in this respect. At present, some basically 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: Zhao Bo (performance of antibacterial and deodorant fiber and its product development, Sichuan Silk, 2004, 4, 27-28); Xue Fulian (development and ap...
