Problems solved by technology

[0004] Peppermint contains flavonoids, phenols, alcohols and organic acids. Directly exposing mint to strong acid, strong alkali and high temperature for spinning will easily decompose the active ingredients in it, which greatly affects the antibacterial properties of the finished fiber
[0005] The modification of wormwood or peppermint extract has not been disclosed in the prior art, and the antibacterial performance of the wormwood or peppermint fiber obtained by directly adding the wormwood or peppermint extract to the fiber will decrease, and it will also affect the mechanical properties of the fiber. Etc performance

Abstract

The invention relates to a wormwood or mint extract modified polyamide fiber and a preparation method thereof. The wormwood or mint extract accounts for 0.1-5mass% of the wormwood or mint extract modified polyamide fiber. According to the preparation method, the wormwood or mint extract and a nano-porous material are mixed and subjected to modification treatment firstly; the nano-porous material has a relatively large specific surface area, and the wormwood or mint extract are packaged in the pore channels of the porous material, so that in the later fiber synthesis, materials in the wormwoodor mint extract can be protected from damage, thereby improving the bacteriostasis rate, the mechanical property and the like; and the wormwood or mint extract is subjected to modified treatment to obtain the modified nano composite material used for preparing the functional master batch, and then spinning is performed, so that uniform mixing is ensured, and the prepared wormwood or mint extract modified polyamide fiber is uniform in performance.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a wormwood or peppermint extract modified nylon fiber and a preparation method thereof. Background technique [0002] The existing conventional viscose fiber is the largest type of regenerated cellulose fiber. The fiber and its follow-up fabric have good moisture absorption and air permeability, and the characteristics of comfortable wearing have always been favored by people. With the development of society, people pay more attention to fabrics. Functional requirements are getting higher and higher. [0003] Wormwood is a perennial herb. The leaves of wormwood are used as medicine. It is warm in nature, bitter in taste, non-toxic, pure in nature, clears the twelve meridians, restores yang, regulates qi and blood, expels dampness and cold, stops bleeding and relieves miscarriage, etc. Efficacy, also commonly used in acupuncture. Wormwood has the specific function o...
