Abstract

The invention discloses an antibacterial nylon filament. The filament comprises a skin layer fiber and a core layer fiber, wherein the skin layer fiber comprises, by weight, 40-60 parts of polyamide resin and 10-20 parts of antibacterial agent. According to a production method of the antibacterial nylon filament, the composite filament comprises the skin layer fiber and the core layer fiber, and is excellent in mechanical property and strong in antibacterial ability.

Description

technical field [0001] The invention relates to a filament material, in particular to an antibacterial nylon filament and a production method thereof. Background technique [0002] The scientific name of nylon is polyamide fiber, which is the general name of polyamide fibers produced in China. Internationally known as nylon. High strength, wear resistance, good resilience, can be purely spun or blended for various clothing and knitwear. The main varieties are nylon 6 and nylon 66, and their physical properties are similar. Nylon has better hygroscopicity and dyeability than polyester, and is resistant to alkali but not acid. Its fiber strength will decrease when exposed to sunlight for a long time. Nylon has heat setting properties and can maintain the bending deformation formed when heated. Nylon filaments can be made into elastic yarns, and short yarns can be blended with cotton and acrylic to improve its strength and elasticity. In addition to the application in cloth...
