Abstract

The invention relates to a producing method of a three-warp three-weft light and thin fabric. The producing method comprises the steps that PET is selected as a warp and weft yarn raw material, and the fabric weave is plain grids; warp yarns undergo winding, twisting, slashing, spooling, beaming and drafting, weft yarns undergo winding, twisting, sizing and spooling, the warp yarns and the weft yarns are knitted, and then after finishing is performed to obtain the three-warp three-weft light and thin fabric. The produced three-warp three-weft light and thin fabric adopts loose and smooth yarnsand has full hand feel, a knitting process is low in cost and high in efficiency, and the producing method has the good application prospect in the fields of umbrella covers, down jackets, surgical gowns, foods, medicine, precise and electronic cleanroom suits and the like.

Description

technical field [0001] The invention belongs to the field of umbrella fabrics, in particular to a preparation method of a light and thin fabric with three warps and three wefts. Background technique [0002] With the advent of summer and autumn every year, the streets form a natural stage for umbrellas. Whether it is raining heavily or scorching hot, red, yellow, white, purple, green, all kinds of umbrellas are like blooming flowers, colorful and vying for beauty, forming a city. A beautiful landscape. Umbrellas originally used for sunshade and rain protection have also developed from a single function to diversification, fashion, and high-end. [0003] After sharing bicycles, shared umbrellas have also quietly appeared. As a new form of sharing economy, shared umbrellas mainly provide umbrella sharing services in some subway or bus stations, commercial areas, residential areas, hotels, etc. At first, it was only trial run in Guangzhou, Shenzhen and Shanghai, but now it ...
