The relationship and difference between spunbond fabric and non-woven fabric

relation
Spunbond and non-woven fabrics are subordinate. There are many production processes for the manufacture of non-woven fabrics, of which spunbond is one of the non-woven production processes (including spunbond, meltblown, hot-rolled, water-punched, most of which are currently on the market). Nonwovens produced by the spunbond method)
According to the composition of non-woven fabrics, there are polyester, polypropylene, nylon, spandex, acrylic, etc.; different components will have completely different styles of non-woven fabrics. The spunbond fabric usually refers to polyester spunbond and polypropylene spunbond; and the styles of these two kinds of fabrics are very similar, and can only be judged by high temperature test.

the difference
Needle-punched non-woven fabrics and spunlace non-woven fabrics belong to non-woven fabrics (also known as non-woven fabrics), which are two of the dry/mechanical reinforcement in non-woven fabrics. Among them, as the name suggests, the biggest difference between the two processes is that the first reinforcement is mechanical needle reinforcement and the other is mechanical high pressure water needle reinforcement. The difference in process directly makes the finished product function and application different.
The production weight of needle punched non-woven fabrics is generally higher than that of spunlace non-woven fabrics. The raw material of spunlace non-woven fabric is more expensive, the cloth surface is more delicate, and the production process is cleaner than acupuncture. It is widely used in health care/hygiene/beauty. Acupuncture raw materials are more extensive than spunlace, and there are many varieties, such as filter material*/felt/geotextile, etc.
The difference between acupuncture and spunlace: acupuncture is generally thicker, the gram weight is generally more than 80 grams, the fiber is thicker, the feel is rough, and there are small pinholes on the surface. The common weight of spunlace is below 80 grams, and the special ones are 120-250 grams, but very few. The spunlace cloth has a delicate feel, and the surface has small strip-shaped spunlace lines in the longitudinal direction.
