What is a nonwoven?
It is a fabric that does not need to be spun woven fabric, but the woven short fibers or filaments are oriented or randomly stretched to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. It directly utilizes high-polymer chips, staple fibers or filaments to form new fiber products with soft, permeable and planar structures formed by various web forming methods and consolidation techniques. To put it simply: It is not woven and braided together by one yarn, but the fibers are bonded directly by physical means, so when you get the sticky name in your clothes , you will find that it is impossible to draw a single thread. Nonwoven 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.
Its main uses can be roughly divided into:
(1) Medical and sanitary cloth: surgical gowns, protective clothing, sterile cloth, masks, diapers, women’s sanitary napkins, etc.;
(2) Household decorative cloth: wall coverings, tablecloths, bed sheets, bedspreads, etc.;
(3) Cloth with lining: lining, adhesive lining, flake, styling cotton, various synthetic leather fabrics, etc.;
(4) Industrial fabrics: filter materials, insulating materials, cement bags, geotextiles, coated cloths, etc.;
(5) Agricultural cloth: crop protection cloth, nursery cloth, irrigation cloth, heat preservation curtain, etc.;
(6) Others: space cotton, thermal insulation materials, oil absorbing felt, smoke filter, bag and tea bags.
