Description

A waterproof and light-proof polyester fabric

technical field

The utility model relates to the technical field of textiles, in particular to a waterproof and light-proof polyester fabric.

Background technique

Fabrics are made of various fibers twisted to form yarns, the yarns are arranged in a certain order, and then the yarns in another direction are interspersed on the yarns, so that a specific weaving structure is formed between the yarns, thereby form fabric.

In the process of use, due to the fact that it is inevitable to encounter water when wearing, when the fabric is wet, it is easy to transmit light, because the fluff on the yarn is easy to stick together after it is wet, so that the yarn is blocked. The material is reduced, so that a larger gap is formed between the yarns, so that the fabric has a phenomenon of light transmission. When the water-swellable yarn is used as the yarn of the fabric, after dehydration, the size of the water-swellable yarn changes, making the yarn The distance between the threads changes, so that there is a large gap near the water-swelling yarn, which makes some yarns unevenly distributed, resulting in light transmission.

The utility model proposes a new technical solution to solve the problems of light transmission and poor moisture drainage performance after the fabric is wetted with water.
