Main differences between spunlaced nonwoven fabrics and needled nonwoven fabrics
1. The gram weight of needled nonwovens is generally higher than that of spunlaced nonwovens. The raw material of spunlaced nonwovens is more expensive, the cloth surface is more delicate, and the production process is cleaner than that of needled nonwovens. Spunlaced nonwovens are widely used for medical, sanitary and cosmetic purposes. Needling raw materials are more extensive than spunlace, with many varieties, such as filter materials, felt materials, geotextile, etc.
2. The difference between acupuncture and spunlace: acupuncture is generally thicker, and the manufacturer of spunlace non-woven fabric with a weight of more than 80g is generally thicker, the fiber is thicker, the handle is rough, and the surface has small pinholes. The most common spunlace cloth is below 80g, and the special one is 120-250g, but few. The spunlaced fabric has a delicate feel, and the surface has a small strip of spunlaced texture in the longitudinal direction.
3. Needle-punched non-woven fabrics and spunlaced non-woven fabrics are non-woven fabrics, which are two of the dry mechanical reinforcement of non-woven fabrics. As the name implies, the biggest difference between the two technologies is the mechanical needle reinforcement and the mechanical high pressure water needle reinforcement. The different superfine fiber nonwoven fabrics in the technology directly make the functional application of the finished products different.
