Preparation method of light composite layer waterproof protective fabric

Abstract

The invention discloses a preparation method of a light composite layer waterproof protective fabric. The preparation method comprises the following steps: step 1, obtaining bamboo chips, cooking thebamboo chips, pulverizing the cooked bamboo chips, carrying out degumming by using a biological enzyme to obtain bamboo fibers, and carding the bamboo fibers to obtain textile fibers for later use; step 2, taking chitosan and flax fibers, putting the chitosan and the flax fibers into a 0.5 mol / L acetic acid solution, heating the solution to 80 DEG C, and stirring the solution to obtain a chitosansolution; and step 3, putting the textile fibers obtained in the step 1 into the chitosan solution, and carrying out reacting for 1 hour at 40 DEG C to obtain reaction fibers. According to the preparation method, the natural bamboo fibers are prepared by adopting a physical and chemical combined method, so that the natural characteristics of the bamboo fibers are not destroyed, and the deodorization, antibacterial and ultraviolet-proof functions of the bamboo fibers are reserved; the bamboo fibers are of a long fiber mesoporous structure, have a plurality of pores, and strong breathability, hygroscopicity and wear resistance, and can quickly absorb sweat steam produced by a human body and discharge the sweat steam to the outside, and adjust the microclimate between clothes and the human body.

Description

technical field [0001] The invention relates to the technical field of textile processing, in particular to a preparation method of a lightweight composite layer waterproof protective fabric. Background technique [0002] Waterproof and breathable functional textiles refer to the fact that the sweat vapor produced by the human body does not accumulate and condense between the fabric and the skin during the movement of the human body, but is transmitted to the outside world through the fabric as a medium, thereby realizing the waterproof and breathable function of the textile. It is a functional textile that combines breathability, waterproof, windproof and thermal performance. Compared with the traditional airtight "waterproof fabric", it has two obvious advantages. First, it can reduce sweat between the skin and the fabric. The accumulation of space avoids more water vapor condensation in the clothing in bad weather, and enhances the comfort; second, the waterproof layer mi...

Problems solved by technology

[0004] In view of the above problems, the patent with the existing patent notification number CN109291565B provides a method for preparing a lightweight composite layer waterproof protective fabric, but the processing method recorded in the application destroys the natural characteristics of bamboo, and the deodorization and antibacterial properties of the fiber , The anti-ultraviolet function is obviously reduced. In view of the above problems, an improved preparation method of lightweight composite layer waterproof protective fabric is now provided
