Problems solved by technology

Although this method has obtained comparatively superior anti-acid, alkali, waterproof and oil-proof effects, due to the large amount of film-forming agent used, the fabric feels poor, and the wearing comfort cannot be guaranteed.
At present, there is no research report on the use of microwave technology in waterproof finishing

Abstract

The present invention discloses a waterproof textile, which is a woven or knitted fabric comprising polyester fibers with a waterproof resin film covered on the surface and cellulose fibers with a waterproof resin film covered on the surface, wherein the difference between the thicknesses of the resin film on the cellulose fiber surface and on the polyester fiber surface is 50-200 nm, and the relative dielectric constant of the resin for forming the waterproof resin film is more than or equal to 4. According to the present invention, with the microwave treatment, the waterproof resin migrates from the polyester fiber surface to the cellulose fiber surface, such that the excellent waterproof performance and the washing durability can be obtained even if the use amount of the waterproof resin is reduced.

Description

technical field [0001] The invention belongs to the field of textiles and materials, and in particular relates to a textile with superior waterproof performance obtained through microwave treatment. Background technique [0002] Functional finishing textiles have been widely used in domestic and foreign markets, and the demand for waterproof finishing functional textiles in the international market is increasing. The world's largest clothing retailer GAP, the world's largest retailer Wal-Mart, the US retail giant Target, The European retail giant H&M, the world-renowned clothing manufacturer Benetton, etc., produce and purchase a considerable number of such products in my country every year. [0003] The essence of waterproof finishing is to adsorb a layer of material on the surface of the fabric to make its high-energy surface into a low-energy surface, so as to obtain a fabric with waterproof effect, and the smaller the surface energy, the better the effect. In the 1950s, ...
