Non-woven industry development

Non-woven fabric is a product of the petrochemical industry after the development of plastic cloth (membrane). Compared with plastic cloth (membrane), its characteristics are lightness and good ventilation. Its materials are mostly used in medical and sanitary materials and environmental protection, such as sanitary napkins, facial towels, and Filters, etc., which were later developed and applied in engineering such as process tubes. Agricultural origin non-woven fabrics are used in vegetable production to prevent cold damage.

The Medical Non Woven Fabric is different from the general plastic film or cloth in its production process. The basic materials are almost the same raw materials, such as PVC (polyvinyl chloride), PE (polyethylene), EVA (Ethylene Vinyl Acetate copolymer), PVA (polyvinyl alcohol), and so on.

The traditional plastic film is formed into a thin film after the plastic is melted and inflated. Basically, the film is continuous. The material extends indefinitely. The surface of the film does not have any pores. It is a completely impermeable film. Block the movement and exchange of any molecules on both sides.

After the expansion of the textile industry, chemical fibers, that is, artificial fibers made from the above-mentioned raw materials replaced most natural plant fibers and became the darling of the textile industry. But basically, these chemical fibers are still formed into cloth through the traditional warp and weft weaving.
