The characteristics of pet wet non-woven fabric

The exact name of non-woven fabric should be non-woven fabric, or non-woven fabric. According to different processes, non-woven fabrics can be divided into: spunlace non-woven fabrics, heat-bonded non-woven fabrics, pulp air-laid non-woven fabrics, wet-laid non-woven fabrics, spunbonded non-woven fabrics, meltblown non-woven fabrics, needles Stab non-woven fabric, stitch-bonded non-woven fabric.


Among them, the pet wet-laid non-woven fabric refers to a fiber network made by dehydrating water, fibers and chemical additives in a special former, and then after physical or chemical processing, it has a cloth appearance And certain properties of non-woven fabrics. It originated from long-fiber papermaking technology, and has followed many papermaking processes and equipment, and is very similar to the appearance and certain properties of paper. More precisely, it should be called 'non-woven paper'.


The pet wet-laid non-woven fabric has the following remarkable characteristics:


1. It is a kind of water-repellent non-woven fabric. The water-repellent properties of non-woven fabrics are different according to the difference in gram weight. If there are water droplets on the surface of the non-woven fabric, the water droplets will slide directly off the surface.


Two, high temperature resistance, because the melting point of polyester is around 260°C, it can maintain the stability of the non-woven fabric's dimensions in an environment that requires temperature resistance. Therefore, this material has been widely used in heat transfer printing, transmission oil filtration, and some composite materials that require high temperature resistance.
