Non-woven fabrics do not have latitude and longitude lines, cutting and sewing are very convenient, and light and easy to shape, loved by hand-lovers.
Because it is a kind of fabric that does not need spinning woven fabrics, but the textile short fibers or filaments are oriented or randomly arranged to form a web structure, and then reinforced by mechanical, thermal adhesive or chemical methods.
Instead of being intertwined and braided together by a single piece of yarn, the fibers are physically bonded together, so when you get the sticky name in your clothes, you will find that It is impossible to extract the root of a root. Non-woven fabrics break through the traditional textile principles, and have the characteristics of short process flow, fast production rate, high output, low cost, wide use, and many raw material sources.
The relationship between nonwovens and spunbonds
Spunbonded fabrics are non-woven fabrics. There are many production processes for the manufacture of nonwovens, of which spunbonding is one of the non-woven production processes.
(Including spunbonding, meltblowing, hot rolling, and hydroentanglement, most of the nonwovens currently produced in the market are spunbonded)
Non-woven fabrics based on the composition, there are polyester, polypropylene, nylon, spandex, acrylic, etc.; different components will have different styles of non-woven fabrics. Spunbonded fabrics are usually referred to as polyester spunbonds and polypropylene spunbonds. The styles of these two fabrics are very close and can only be determined by high temperature testing.
Non-woven fabric is a kind of non-woven fabric. It directly uses polymer chips, short fibers or filaments to wind the fibers through airflow or mechanical web, and then it is hydro-entangled, needle-punched, or hot-rolled, and finally finished. Non-woven cloth formed. The new fiber products with a soft, breathable and planar structure have the advantage of not producing lint, strong, durable, silky soft, but also a kind of reinforcing material, but also a cottony feel, compared with cotton, non-woven Cloth bag is easy to form and cheap.
