Spunbonded fabrics are subordinate to non-woven fabrics. There are many production processes for nonwoven fabrics, among which spinning-bonding is one of them (including spinning-bonding, melt-blown, hot-rolling and spunlaced methods). Nowadays, most of the nonwoven fabrics are produced by spinning-bonding method on the market.
According to the composition of non-woven fabric, there are polyester, polypropylene, nylon, spandex, acrylic and so on; different components will have completely different style of non-woven fabric. Spunbonded fabrics usually refer to polyester spunbonded and polypropylene spunbonded fabrics, and the style of these two fabrics is very similar, which can be distinguished by high temperature test.
Non-woven fabric is a kind of non-woven fabric. It is a kind of non-woven fabric that directly uses polymer chips, staple fibers or filaments to form fibers through air flow or mechanical netting, then through spunlace, needle-punching, or hot-rolling reinforcement, and finally after finishing. A new type of fibre product with soft, breathable and flat structure has the advantages of not producing fibre chips, strong, durable, silky softness, but also a kind of reinforcing material. It also has the feeling of cotton. Compared with cotton fabric, non-woven bags are easy to form, and the cost is low.
