What fabric is non-woven fabric? What are the characteristics of non-woven fabrics? Non-woven fabrics, also known as non-woven fabrics, are made up of directional or random fibers and are a new generation of environmentally friendly materials, it has the characteristics of moisture-proof, breathable, flexible, light weight, no combustion-supporting, easy decomposition, non-toxic and non-irritating, rich in color, low price, and recyclable. For example, polypropylene pellets are used as raw materials and are produced by continuous one-step process of high-temperature melting, wire spraying, winding and hot pressing. It is called a cloth for its appearance and certain properties. Because it is a fabric formed without spinning and weaving, it only directs or randomly arranges textile staple fibers or filaments to form a fiber mesh structure, then it is reinforced by mechanical, thermal or chemical methods. Non-woven fabrics are made of polyester, polypropylene, nylon, spandex, acrylic, etc; Different ingredients will have completely different non-woven styles. The spunbond cloth usually refers to polyester spunbond and polypropylene spunbond; The styles of these two kinds of cloth are very close and can only be judged by high temperature test. Non-woven fabric is a kind of non-woven fabric, which directly uses polymer slices, short fibers or filaments to make fibers through air flow or mechanical mesh, and then through Spurs, acupuncture, or hot rolling reinforcement, finally, the unwoven fabric formed after finishing. The new fiber product with soft, breathable and planar structure has the advantages of not producing fiber chips, being strong, durable and silky, is also a kind of reinforced material, and also has the feeling of cotton, compared with cotton fabrics, non-woven bags are easy to form and cost. What are the characteristics of non-woven fabrics? Non-woven fabrics are not interwoven and knotted by one yarn, but are bonded directly by physical means. Therefore, when you get the stick in your clothes, you will find that you can't draw a thread. Non-woven fabric breaks through the traditional textile principle and has the characteristics of short process flow, fast production rate, high output, low cost, wide use and many sources of raw materials.
