Embodiment 1

[0027] Dissolve 2.5kg of copper sulfate pentahydrate in 100kg of water, add 4kg of tetraethylenepentamine, and then add 10kg of zirconium phosphate carrier after stirring, stir for 24 hours, wash, filter, dry, and pulverize to obtain an amine content of 10%, The anti-mildew and deodorizing agent with copper content of 5.5% (both by weight percentage). The particle size distribution of the anti-mold and deodorant is as follows: figure 1 As shown, among them, d(0.1)=0.522um, d(0.5)=0.953um, d(0.9)=1.724um.

[0028] In the nylon 6 polymerization process, the above-mentioned anti-mildew and deodorizing agent is added at 1.2% to make nylon 6 slices. Long-acting anti-mold, deodorizing and hygroscopic nylon fibers are obtained by melting nylon 6 slices containing anti-mildew and deodorizing agents and spinning through a spinneret with a special-shaped cross-section of "T" shape.

[0029] The long-acting anti-mold, deodorizing and hygroscopic nylon fiber is tested according to the A...

Embodiment 2

[0031] Dissolve 6kg of copper sulfate pentahydrate in 100kg of water, add 5kg of tetraethylenepentamine, add 10kg of zirconium phosphate carrier after stirring, stir for 24 hours, wash, filter, dry, and grind to obtain amine content of 15%, containing Anti-mildew deodorizer with 10.5% copper.

[0032] In the nylon 6 polymerization process, the above-mentioned anti-mildew and deodorizing agent is added at 0.5% to make nylon 6 slices. Long-acting mildew-proof, deodorizing and hygroscopic nylon fibers are obtained by melting nylon 6 slices containing anti-mildew and deodorizing agents, and then spinning through a spinneret with a special-shaped cross-section of "Y" shape.

[0033] The long-acting anti-mold, deodorizing and hygroscopic nylon fiber is tested according to the AATCC 30-2004 standard, and the anti-mold grade is 1 and does not grow.

Embodiment 3

[0035]Dissolve 4kg of copper sulfate pentahydrate in 100kg of water, add 2.8kg of triethylenetetramine, add 10kg of zirconium phosphate carrier after stirring, stir for 24 hours, wash, filter, dry, and pulverize to obtain an amine content of 10%, Anti-mildew deodorizer with 7.9% copper.

[0036] In the nylon 6 polymerization process, the above-mentioned anti-mildew and deodorizing agent is added at 1% to make nylon 6 slices. Long-acting mildew-proof, deodorizing and hygroscopic nylon fibers are obtained by melting nylon 6 slices containing anti-mildew and deodorizing agents and spinning through a spinneret with a cross-shaped cross-section.

[0037] The long-acting anti-mold, deodorizing and hygroscopic nylon fiber is tested according to the AATCC 30-2004 standard, and the anti-mold grade is 1 and does not grow.

[0038] The long-acting anti-mildew, deodorizing and hygroscopic nylon fibers obtained in Examples 1-3 have the original excellent characteristics and anti-mold prop...

Abstract

The invention relates to a long-acting mildew-resistant odor-removing moisture-absorbing polyamide fiber and a preparing method thereof. The preparing method includes steps of: (1) preparing a mildew-resistant odor-removing agent, with the active components of the mildew-resistant odor-removing agent being amine and copper, and a carrier being zirconium phosphate; and (2) adding the mildew-resistant odor-removing agent into polyamide 6, and spinning by a profile spinneret to obtain the long-acting mildew-resistant odor-removing moisture-absorbing polyamide fiber. Compared with the prior art, the long-acting mildew-resistant odor-removing moisture-absorbing polyamide fiber adopts the zirconium phosphate to carry a conjugate of the amine and the copper, has characteristics of high carrying amount and low adding amount. Release of the active components is controlled so that the fiber and fabrics thereof have mildew resistance, odor-removing performance and safety. A moisture-absorbing property brought by fiber profiling and mildew-resistant odor-removing properties are combined, thus promoting dissociation of the amine and the copper, and further improving mildew resistance and odor-removing properties of the fiber and the fabrics thereof.

Description

technical field [0001] The invention relates to a mildew-proof fiber and a preparation method thereof, in particular to a long-acting mildew-proof, deodorizing and hygroscopic nylon fiber and a preparation method thereof. Background technique [0002] With the improvement of living standards, people pay more and more attention to the comfort performance of clothing, and the various high-tech contents of clothing fabrics are also getting higher and higher. Nylon itself has excellent properties such as silk touch, good resilience and good wear resistance, so it is widely used in underwear, sportswear, shirts, swimsuits, socks, etc. and fabrics that are in direct contact with the skin. With the substantial improvement of living standards, the public has put forward higher and higher requirements for the health care functions of these fabrics, and the demand for functional fabrics such as mildew resistance, deodorization, and moisture absorption has also increased year by year. ...
