A synthetic fiber obtained by spinning a polyester obtained by polycondensing an organic dibasic acid and a diol. The industrially mass-produced polyester fiber is made of polyethylene terephthalate, and the Chinese name is polyester. It is the first large variety of synthetic fibers.
Polyester non-woven fabric: a fabric that does not require spinning and weaving. The woven short fibers or filaments are oriented or randomly stretched to form a web structure, and then mechanically, thermally bonded or chemically. Reinforced.
Features: Non-woven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production speed, high output, low cost, wide application and many raw materials.
Industrial non-woven fabrics: filter materials, insulating materials, cement bags, geotextiles, coated cloths, etc.
Uses: Mainly used for construction construction, roof waterproofing as the base fabric, with sand, cement, etc. on it, to prevent sand from leaking. Non-woven fabrics are often used in construction and are a measure to prevent cracks.
