Nonwovens, also known as non-woven fabrics, are constructed of oriented or random fibers. It is called a cloth because it has the appearance and some properties of the cloth.
The non-woven fabric has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. For example, polypropylene (pp material) pellets are used as raw materials, which are produced by high-temperature melting, spinning, paving, and hot-rolling and continuous one-step process.
The non-woven fabric has no latitude and longitude lines, is very convenient for cutting and sewing, and is light and easy to shape. It is very popular among handicraft lovers.
Because it is a fabric that does not require spinning woven fabric, only the woven short fibers or filaments are oriented or randomly arranged to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods.
Instead of interlacing and braiding the yarns one by one, the fibers are bonded directly together by physical means, so when you get the sticky name in your clothes, you will find that It is impossible to draw a single thread. Nonwoven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production rate, high output, low cost, wide application and many sources of raw materials.
The relationship between non-woven fabric and spunbond fabric
Spunbond and non-woven fabrics are affiliation. There are many production processes for the manufacture of non-woven fabrics, among which the spunbonding method is one of the non-woven fabric production processes (including spunbonding, meltblowing, hot rolling, and hydroentangling, which are mostly on the market). Non-woven fabric produced by spunbonding)
According to the composition of the non-woven fabric, there are polyester, polypropylene, nylon, spandex, acrylic, etc.; different ingredients will have different non-woven styles. The spunbond fabric usually refers to polyester spunbond and polypropylene spunbond; and the styles of the two fabrics are very close, which can be judged by high temperature test.
Non-woven fabric is a kind of non-woven fabric, which directly uses high polymer chips, short fibers or filaments to pass the fibers through airflow or mechanical netting, and then through hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishing. Formed non-woven fabric. The new fiber product with soft, breathable and flat structure has the advantages of no lint formation, strong, durable, silky softness, also a kind of reinforcing material, and also a cotton feeling, compared with cotton, non-woven The cloth bag is easy to form and is cheap to make.
