It is a fabric that does not require spinning and weaving. It is just oriented or randomly arranged short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. It directly utilizes polymer chips, short fibers or filaments to form a new type of fiber product with soft, breathable and planar structure formed by various web forming methods and consolidation techniques.

China's national standard GB / T 5709-1997 "Textile Nonwovens Terminology" defines nonwoven fabrics: oriented or randomly arranged fibers, combined with each other by friction, entanglement, or adhesion, or a combination of these methods Formed sheets, webs or batts, excluding paper, woven fabrics, knitted fabrics, tufted fabrics and wet-shrinked felts. To put it simply: it is not interwoven and braided by individual yarns, but the fibers are directly bonded together by physical methods, so when you get the sticky name in your clothes , You will find that you can't pull out any thread. Non-woven fabrics break through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide use, and many sources of raw materials.
Its main uses can be roughly divided into:
(1) Medical and sanitary cloths: surgical gowns, protective clothing, disinfecting cloths, masks, diapers, women's sanitary napkins, etc .;
(2) Fabrics for home decoration: wall stickers, tablecloths, bed sheets, bed covers, etc .;
(3) Cloth for clothing: lining, adhesive lining, flakes, shaped cotton, various synthetic leather base fabrics, etc .;
(4) Industrial fabrics: filter materials, insulating materials, cement bags, geotextiles, covering fabrics, etc .;
(5) Agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc .;
(6) Others: space cotton, thermal insulation and sound insulation materials, linoleum, cigarette filter, tea bags, etc.
