2. Because it is a kind of fabric that does not need to be spun and woven, but is made of short fibers orfilamentThe structure is formed by directional or random arrangement, and then reinforced by mechanical, thermal adhesive or chemical methods.

3. It's not made up of individual piecesyarnInstead, the fibers are physically bonded together, so when you get to the scales in your clothes, you'll find that you can't pull out the threads.Nonwoven fabricIt breaks through the traditional textile principle, and has the characteristics of short technological process, fast production rate, high yield, low cost, wide application and many sources of raw materials.

4. The relationship between non-woven and spunbonded fabrics

5. Spunbonded fabrics are subordinate to non-woven fabrics. There are many production processes for the manufacture of non-woven fabrics, among which the spunbonded process is one of the non-woven production processes (including spunbonded process, melting spray process, hot rolling process and spunlaced process, most of which are produced by spunbonded process in the market now).

6. Non-woven fabrics according to the composition, therepolyester,polypropylene, polyamide,spandex, acrylic fiber, etc. Different ingredients can have completely different styles of non-woven fabrics. And spunbonded cloth, usually refers to polyester spunbonded, polypropylene fiber spunbonded; The styles of the two cloths are very similar and can only be identified by high temperature tests.

7. Non-woven fabric is a kind of non-woven fabric, which is directly made of polymer chips.Short fiberA braided fabric that is formed by spinning the fibers through an air stream or machine and then being reinforced by spines, needles, or hot rolling. New fiber products with soft, breathable and flat structure have the advantage of no fiber chip, strong, durable, silky soft, is also a kind of reinforcing material, and also have the feeling of cotton, compared with cotton fabric, non-woven fabric bags are easy to form, and the cost is low.
