preparation example 1

[0037] The preparation method of nano-silver / chitosan / polylactic acid composite fiber is: 1) polylactic acid resin is sliced, and after carrying out vacuum drying, is heated to molten state, makes molten liquid; 2) chitosan is dissolved in 0.5% acetic acid aqueous solution, and stir evenly to obtain a chitosan solution; 3) add the amino nano-silver solution and the chitosan solution to the melt, and stir evenly to obtain a blend, the amino nano-silver solution, the shell The mass ratio of polysaccharide solution to polylactic acid melt is 0.1:0.4:1; 4) Extrude, filter, spin, cool, and stretch the blend to obtain nano silver / chitosan / poly Lactic acid composite fiber.

preparation example 2

[0039] The preparation method of nano-silver / chitosan / polylactic acid composite fiber is: 1) polylactic acid resin is sliced, and after carrying out vacuum drying, is heated to molten state, makes molten liquid; 2) chitosan is dissolved in 0.5% acetic acid aqueous solution, and stirred evenly to obtain a chitosan solution, uniformly disperse nano-titanium dioxide into the chitosan solution, the mass ratio of nano-titanium dioxide to chitosan solution is 0.5:1.7, to obtain nano-titanium dioxide / chitosan dispersion; 3) amino nano-silver solution and nano-titanium dioxide / chitosan dispersion are added in the molten liquid, stir evenly, make blend, amino nano-silver solution, nano-titanium dioxide / chitosan dispersion The mass ratio to the polylactic acid melt is 0.1:0.4:1; 4) The blend is extruded, filtered, spun, cooled, and stretched to prepare nano-silver / chitosan / polylactic acid composite fibers.

preparation example 3

[0041]The preparation method of the nano-silver / polylactic acid composite fiber is as follows: 1) slice the polylactic acid resin, and after vacuum drying, heat to a molten state to obtain a melt; 2) add the amino nano-silver solution into the melt, and stir evenly , to obtain a blend, the mass ratio of the amino nano-silver solution to the polylactic acid melt is 0.5:1; 3) the blend is extruded, filtered, spun, cooled, and stretched to obtain a nano-silver / Polylactic acid composite fiber.

Abstract

The invention relates to the field of clothes, and particularly discloses antibacterial thermal underwear and a production process thereof. The antibacterial thermal underwear comprises a surface layer, wherein the surface layer is formed by blending various fibers including antibacterial fibers, and the antibacterial fibers are nano-silver / chitosan / polylactic acid composite fibers; the preparation method of the antibacterial thermal underwear comprises the following steps of S1, spinning, namely, blending various fibers including the antibacterial fibers to prepare blended yarns; S2, weaving,namely, weaving the blended yarns by adopting a single-sided and double-sided alternate weaving mode to weave gray cloth; S3, napping, namely, napping the skin-friendly surface of the gray cloth to obtain napped gray cloth; S4, dyeing, namely, dyeing the napped gray cloth; and S5, sewing, namely, sewing the dyed napped gray cloth to prepare a finished product of the thermal underwear. The thermalunderwear prepared by the invention has good lasting antibacterial property.

Description

technical field [0001] The application relates to the field of clothing, more specifically, it relates to an antibacterial thermal underwear and a production process thereof. Background technique [0002] Thermal underwear is a kind of warm clothing that can be worn next to the body. It is suitable for late autumn and cold winter. It is light and easy to wear without being bloated. Because people wear more clothes in winter, it is easy to cause bacteria to grow on the thermal underwear next to the body after sweating. However, the thermal underwear currently on the market is usually made of several blends of cotton fiber, hemp fiber, wool, rabbit down or synthetic fibers. None of the above materials has excellent antibacterial properties, resulting in the need to improve the antibacterial properties of thermal underwear. . [0003] The current related technology is: adding nano-silver to thermal underwear to make antibacterial underwear to improve the antibacterial propert...
