[0033] A method for preparing anti-mite polyamide fiber, which is prepared from the following raw materials in weight percentage: 100-250 parts of polyamide fiber, 1-5 parts of chrysanthemum acid compound, 200-500 parts of solvent, and 0.10-10 parts of dehydrating agent parts and a small amount of catalyst.

[0034] (1) Put the raw materials into the reactor according to the ratio of 1-5 parts of chrysanthemic acid compound and 200-500 parts of solvent, and dissolve at 40°C-110°C;

[0035] (2) Add 0.10-10 parts of dehydrating agent and 0.1-0.5 parts of catalyst to the solution obtained in step (1), mix well, then add 100-250 parts of polyamide fiber, adjust the temperature to the reflux temperature, and dry in ultrasonic or Reflux reaction under inert gas stirring for 1~10h;

[0036] (3) After the reaction is completed, take out the polyamide fiber and centrifuge to recover the solution;

[0037] (4) The polyamide fibers from which the solution has been removed by centrifuga...

Embodiment 1

[0039] (1) Put the raw materials into the reactor according to the ratio of 1 part of allylchrysanthemic acid and 200 parts of ethanol, and dissolve at 70°C;

[0040] (2) Add 2 parts of phosphorus pentoxide and 0.1 part of hydrochloric acid to the solution obtained in step (1), mix well, then add 100 parts of nylon-6 fiber, adjust the temperature to the reflux temperature, and reflux for 1 hour under ultrasonic stirring ;

[0041] (3) After the reaction is completed, take out the nylon-6 fiber and centrifuge to recover the solution;

[0042] (4) The nylon-6 fibers from which the solution has been removed by centrifugation are washed with water at 40°C until neutral and then dried to obtain the anti-mite nylon-6 fibers.

Embodiment 2

Abstract

The invention discloses an anti-mite polyamide fiber and a preparation method thereof. The anti-mite polyamide fiber is prepared from the following raw materials in parts by weight: 100-250 parts of polyamide fiber, 1-5 parts of chrysanthemic acid compound, 200-500 parts of solvent, 0.10-10 parts of dehydrating agent and 0.1-0.5 part of catalyst. In the invention, chrysanthemic acid with anti-mite function reacts with the polyamide fiber, so that carboxyl in the chrysanthemic acid molecule and amino in the polyamide molecule are subject to a condensation reaction to further obtain the polyamide fiber with anti-mite function. The chrysanthemic acid is bonded with polyamide macromolecule to improve the stability and is not easy to loss in usage, the washing fastness is increased, and meanwhile, the safety is improved.

Description

technical field [0001] The invention belongs to the technical field of polyamide fibers, and in particular relates to an anti-mite polyamide fiber and a preparation method thereof. Background technique [0002] With the development of world building technology and the enrichment of people's material life, great changes have taken place in the indoor living environment. The improvement of the airtight performance of the house makes indoor pollution gather, and poor ventilation increases the growth of indoor bacteria and mites. Mites are small arthropods with a body length of 0.1-0.5mm. It is difficult for people to observe them with the naked eye. Mites can parasitize on the surface of humans or other organisms to sting or sting, suck blood, and spread diseases. Or other organisms can cause allergic diseases, cause various diseases such as asthma, rhinitis, dermatitis, tinea corporis, and cause serious harm to human health. There are three main types of anti-mite methods fo...
