Abstract

The invention provides a polyamide6 fiber with the antibacterial and moisture absorption and sweat releasing functions. The polyamide6 fiber is prepared from cuprous-oxide antibacterial master batches and sliced polyamide6, wherein the weight ratio of the cuprous-oxide antibacterial master batches to the sliced polyamide6 is (2-10):(90-98); the mixture is mixed, melted, extruded and spun through a deformed section spinneret plate, and the polyamide6 fiber is prepared. The invention also provides a preparing method of the polyamide6 fiber. The polyamide6 fiber and the preparing method thereof have the advantages that the polyamide6 fiber is modified through the cuprous-oxide antibacterial master batches, the cuprous-oxide antibacterial master batches and the sliced polyamide6 are mixed to be spun through the deformed section spinneret plate, and the prepared polyamide6 fiber has the antibacterial and moisture absorption and sweat releasing functions at the same time, the antibacterial rate of the polyamide6 fiber to candida albicans reaches 95% or above, the antibacterial rates to staphylococcus aureus and escherichia coli reach 99% or above, the fabric woven by the polyamide6 fiber can rapidly absorb and guide moisture, and the polyamide6 fiber has the lasting and efficient antibacterial performance.

Description

technical field [0001] The invention relates to the field of textile processing, in particular to a polyamide 6 fiber and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's requirements for clothing are no longer limited to keeping warm, but tend to have clothing fabrics with various additional functions such as antibacterial properties, breathability, and moisture absorption. In recent years, global environmental problems have become increasingly serious. Harmful bacteria in the environment continue to breed and multiply. The upgrading of drugs can no longer completely avoid the huge threat posed by bacteria to human health. In addition, with the increasing greenhouse effect, the amount and time of use of air conditioners are also increasing. Air conditioning refrigeration will undoubtedly continue to aggravate global warming while consuming energy. [0003] Therefore, it is necessary to be able to modify...
