Non woven fabrics refer to nonwovens, or non wovens. It is a kind of fabric formed without spinning and weaving. It is only formed by directional or random support of textile short fibers or filaments to form a fiber web structure, and then reinforced by mechanical, thermal bonding or chemical methods., It is moisture-proof, breathable, flexible, light, non combustion supporting, easy to decompose, non-toxic and non irritating, rich in color, low price, recyclable and so on. It is a kind of fabric formed without spinning and weaving. It is only formed by directional or random support of textile short fibers or filaments to form a fiber web structure, and then reinforced by mechanical, thermal bonding or chemical methods.
Non woven fabrics are not interwoven and braided by yarns one by one, but the fibers are directly bonded together by physical methods. Therefore, when you get the adhesive scale in your clothes, you will find that you can't pull out the thread ends one by one. Nonwovens break through the traditional textile principle, and have the characteristics of short process flow, fast production rate, high output, low cost, wide application and many sources of raw materials.
Non-woven fabrics are used in a variety of industries for different purposes. Non-woven fabrics are typically used as an easy way to create heat reflective insulation, which is usually seen in the insulation of jackets and campers.
Non-woven fabrics can be made into air filters for heating or cooling systems, used as disposable wipes that are commonly found in bathrooms, or used as a substitute for cotton batting found in quilts.
These sheets are then glued to each other to form a textile that is less expensive than regular fabrics and does not fray as easily. Non-woven fabrics have many advantages over regular textiles, including being water resistant and providing better thermal insulation.
Spunbonded fabric and non-woven fabric are subordinate. There are many production processes for the manufacture of non-woven fabrics, among which spunbonded method is one of the production processes of non-woven fabrics (including spunbonded method, melt blown method, hot rolling method and water pricking method. Most of the non-woven fabrics on the market are produced by spunbonded method). According to the composition, non-woven fabrics include polyester, polypropylene fiber, nylon, spandex, acrylic fiber, etc; Different components will have different non-woven styles. Spunbonded fabrics usually refer to polyester spunbonded and polypropylene spunbonded; The styles of these two kinds of cloth are very similar, which can be distinguished only through high-temperature test.
3) heat preservation,
4) water absorption,
7) non dishevelled,
8) good feel and softness,
10) elasticity and recoverability,
11) no fabric directionality,
12) high productivity and fast production speed compared with textile fabrics,
13) low price, mass production, etc.
1) poor strength and durability compared with textile cloth,
2) unable to clean like other fabrics, 3) the fibers are arranged in a certain direction, so they are easy to crack from a right angle, etc. Therefore, the recent improvement of production methods mainly focuses on the improvement of preventing division.
