Problems solved by technology

[0002] The existing textile fabrics are easily stained with oil stains during use. The clothes stained with oil stains are very dirty and the oil stains are generally not easy to wash off. Therefore, the textile fabrics stained with oil stains are not suitable for wearing again, which seriously affects the use of textile fabrics in daily life. In the existing technology, butyl rubber is used as a film-forming agent to form an oil-repellent layer on the surface of the textile cloth, but such an oil-repellent layer tends to make the textile cloth lose its air permeability

Abstract

The invention discloses a preparation method of waterproof breathable blended cloth, comprising: making a cooking liquor with bamboo, reed, Cannabis sativa fiber, straws and Apocynum venetum fiber, adding cassava starch, mulberry leaf powder and lemon leaf powder into the cooking liquor to obtain a dialysis solution, adding the dialysis solution into a loom to produce mixed fiber filaments, addingthe mixed fiber filaments into a mixed solution of maleic anhydride, olefin-based carbosiloxane and sodium chloride, treating the mixed solution under an ultraviolet lamp having a wavelength of 330-380 nm for 60-80 nm so as to obtain dry fiber filaments, weaving the dry fiber filaments with the loom to obtain grey cloth, and treating the grey cloth with a textile setting machine to obtain the blended cloth. The blended cloth prepared via the preparation method herein is waterproof and breathable and therefore, has a good application prospect.

Description

technical field [0001] The present invention relates to the textile field. More specifically, the present invention relates to a method for preparing a waterproof and breathable blended fabric. Background technique [0002] The existing textile fabrics are easy to be stained with oil stains during use. The clothes stained with oil stains are very dirty and the oil stains are generally not easy to wash off, so the textile fabrics stained with oil stains are not suitable for wearing again, which seriously affects the textile fabrics in daily life. In the existing technology, butyl rubber is used as a film-forming agent to form an oil-repellent layer on the surface of the textile cloth, but such an oil-resistant layer tends to cause the textile cloth to lose its air permeability. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be described later. [0...
