ES fibres containing wormwood extractive, and preparation method thereof

Abstract

The invention provides ES fibres containing a wormwood extractive, and a preparation method thereof. The content of the wormwood extractive in the ES fibres is 0.1-5%. The preparation method thereof comprises preparation of a functional modifier containing the wormwood extractive, preparation of a skin layer material, preparation of a core layer material, composite spinning and post-processing. The ES fibres containing the wormwood extractive prepared by the method have the natural bacteriostatic effect; the bacteriostasis rate on escherichia coli is 96.5-99.2%; the bacteriostasis rate on staphylococcus aureus is 95.0-97.2%; the bacteriostasis rate on Candida albicans is 94.5-96.0%; simultaneously, the fibre density of the ES fibres is 0.98-1.20 g / cm3; the fineness is 1.2-1.6 dtex; the breaking strength achieves 6.2-6.6 cN / dtex; the breaking elongation is 4.5-6.0%; and the overall performance of the novel composite fibres is very excellent.

Description

technical field [0001] The invention belongs to the technical field of ES fiber and its preparation, and in particular relates to an ES fiber containing wormwood extract and a preparation method thereof. Background technique [0002] ES fiber is an eye-catching polyolefin fiber developed by Chisso Corporation of Japan. It is a new type of thermal bonding composite fiber. Nonwoven molded body. ES fiber is made by combining two resins with different melting points. Using the difference in melting point between the two, the bonding between fibers can be achieved only through heat treatment. Because it is a clean fiber without using a binder, the ES fiber cross section The form is "skin-core type" or "side-by-side type", which has a wide range of processing suitability. The non-woven fabric processed by ES fiber has good bulkiness, softness and wet elasticity, and is widely used on the surface of sanitary products. layer. [0003] In the existing technology, the application r...

[0004] Invention patent CN106943618B provides a wormwood health-care sanitary napkin and its preparation method. In the preparation process, moxa, antibacterial fiber and ES fiber are evenly mixed, and ingredients such as glutinous rice, mint, and persimmon leaves are used together to improve the health care of wormwood. Towel antibacterial effect, however, it does not add natural antibacterial ingredients to ES fibers during the preparation process

During related experiments, the applicant found that plant extracts are not resistant to high temperatures, and when they are melt-blended with ES fibers to prepare fiber products, they are easily charred or lost, reducing their functionality; and the addition of plant extracts will affect ES fibers. The mechanical strength of the fiber, the air permeability of the fiber product, etc.
