Problems solved by technology

However, light and thin umbrella fabrics are prone to crossbar defects, which is a difficult fabric for shuttleless machines
Due to the fine yarn count and low single yarn strength, a prominent problem in the weaving process is that the warp yarns are easy to break and the menopause pieces are easy to fall, resulting in downtime

Abstract

The invention relates to a preparation method of a light and thin fabric with three warps and three wefts, comprising: selecting PET as the raw material of warp and weft yarns, and fabric weaving as plain lattice; The weft yarn goes through bobbing, twisting, sizing, and winding, and then the warp and weft yarns are weaved, and the three-warp and three-weft light and thin fabric is obtained after finishing. The light and thin fabric prepared by the invention has loose yarns, full hand feeling, low cost and high efficiency of the weaving process, and has good application prospects in the fields of umbrella covers, down jackets, surgical clothes, food, pharmaceuticals, precision electronic clean clothes 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 ...
