Abstract

The invention discloses a breathable water absorption fiber preparation method. The method includes steps: 1) preparing spinning melt; 2) extruding the melt through spinneret holes to form melt trickles; 3) cooling and solidifying the melt trickles to form nascent fibers; 4) oiling and winding the nascent fibers, wherein the spinneret holes are cross shaped, and cross sections of the prepared fibers are cross shaped correspondingly. The prepared fibers have functions of breathability and water absorption and have great antibacterial, mildew-proof, flame-retardant and wear-resistant performances.

Description

technical field [0001] The invention relates to a preparation method of air-permeable and water-absorbing fibers. Background technique [0002] Fiber (US: Fiber; English: Fiber) refers to a substance composed of continuous or discontinuous filaments. There are many types and applications of fibers, among which textile fibers are fibers used to weave cloth and are necessary raw materials in the textile field. [0003] However, the functions of existing textile fibers are relatively single, which cannot meet the diverse needs of the market. Contents of the invention [0004] The purpose of the present invention is to provide a method for preparing air-permeable and water-absorbing fibers. The prepared fibers have the functions of air-permeable and water-absorbing, and have good antibacterial, mildew-proof, flame-retardant and wear-resistant properties. [0005] In order to achieve the above object, the technical solution of the present invention is to design a preparation ...
