Is 100% polyester all the ingredients in the non-woven fiber?

Non-woven fabric or non-woven fabric, a more accurate name should be called non-woven fabric. The fabric formed by non-woven fabric is because it is a woven fabric that does not require any spinning. It is a woven short fiber or filament that is oriented and randomly arranged to form a fiber network structure, which is then processed by chemical, thermal bonding, and mechanical methods. Become. Non-woven fabric far breaks through the traditional textile principles of the past, and has the characteristics of fast production speed, low cost, high output, wide use, short process flow, and multiple raw materials.

The non-woven fabric fiber composition is not 100% polyester. In the entire non-woven fabric industry, man-made fibers still dominate the production. Among the fibers used in non-woven fabrics, there are 63% polypropylene, 23% polyester, and 8% viscose. , 2% acrylic fiber, 1.5% polyamide, 3% other fiber components.

An important type of synthetic fiber in polyester non-woven fabrics. It is made of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification Polyethylene terephthalate (PET), a fiber-forming polymer made by transesterification and polycondensation, is a fiber made by spinning and post-processing.

Different types of non-woven fabrics have different uses, such as: impregnated non-woven fabrics, needle-punched cotton non-woven fabrics, flame-retardant non-woven fabrics, shoulder pad non-woven fabrics, etc. To choose high-quality non-woven fabrics, you must choose strength A strong non-woven fabric manufacturer.
