Problems solved by technology

[0003] Because underwear needs to be worn close to the body, manufacturers need to carry out antibacterial treatment on the fabric during production. However, the existing underwear knitted fabric has a certain antibacterial effect in a short period of time after antibacterial treatment, but the antibacterial effect is general. The antibacterial effect will decrease after

Embodiment 1

[0036]An antibacterial and comfortable underwear knitted fabric is prepared from bamboo fiber, polyester fiber, spandex fiber, a first dipping solution and a second dipping solution. The specific steps are as follows:

[0037] Step S1: blending bamboo fiber, polyester fiber, and spandex fiber to obtain a composite fabric;

[0038] Step S2: Padding the composite fabric prepared in step S1 in the first impregnating solution, at a temperature of 80° C. and a pH value of 5, padding for 5 hours to obtain the first padding composite gray cloth;

[0039] Step S3: Padding the first padding composite gray cloth prepared in step S2 in the second impregnating solution, and performing padding at a temperature of 90° C. for 5 hours to obtain a second padding composite gray cloth;

[0040] Step S4: padding the second padding composite gray fabric prepared in step S3 in water for 3 hours, and then drying at a temperature of 180° C. to obtain knitted underwear fabric.

Abstract

The invention discloses antibacterial and comfortable underwear knitted fabric and a preparation method thereof. The underwear knitted fabric is prepared from bamboo fibers, polyester fibers, spandex fibers, a first steeping liquor and a second steeping liquor, wherein the second steeping liquor is formed by mixing an antibacterial agent, deionized water and ethyl alcohol according to the proportion of 3 g : 20 mL : 5 mL; when first padding composite gray cloth is padded in the second steeping liquor, siloxane in molecules of the antibacterial agent is hydrolyzed to generate silanol, and the silanol and active hydroxyl groups on the surface of the first padding composite gray cloth form hydrogen bonds, so that the molecules of the antibacterial agent are connected with the surface of the gray cloth; when bacteria make contact with the surface of the fabric, positive charges of pyridine quaternary ammonium salt on the molecules of the antibacterial agent act with a head group of acidic phospholipid in a bacterial cell membrane, so that the cell membrane infiltration capacity is reduced, bacterial cell sap leaks, bacterial cell death is caused, meanwhile, bacterial protein denaturation can be realized by the molecules of the antibacterial agent, bacterial metabolism can be prevented, and bacteria can be killed.

Description

technical field [0001] The invention relates to the technical field of fabric preparation, in particular to an antibacterial and comfortable underwear knitted fabric and a preparation method thereof. Background technique [0002] Underwear refers to clothing worn next to the body, including vests, undershirts, shorts, bras, etc. Underwear refers to clothes worn under other clothes, usually in direct contact with the skin, and is one of the indispensable clothing of modern people. Underwear has the functions of absorbing sweat, correcting shape, setting off the body, keeping warm and not being harmed by the pollution from the body. Ladies choose natural fiber products for underwear, and cotton products are more suitable. It has good moisture absorption and warmth retention properties, and the price is also moderate. But women's underwear is essentially inclusive, so that it can effectively support the breasts and buttocks. In order to improve the tolerance of underwear, s...
