What is the material composition of non-woven fabric? Non-woven products are different from general textiles in terms of material composition. In order to ensure the excellent breathability and flexibility of non-woven fabrics, and improve the stretchability and quality of non-woven fabrics, non-woven fabrics The material composition of the fabric is very different from ordinary textiles!
Non-woven fabrics mostly use polypropylene (pp material) pellets as raw materials, and are produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing.
The three major fibers used in the production of non-woven fabrics are polypropylene (62% of the total), polyester (24% of the total) and viscose fiber (8% of the total). From 1970 to 1985, viscose fiber was used the most in the production of non-woven fabrics. However, in the past five years, the application of polypropylene fiber and polyester fiber has begun to dominate in the fields of sanitary absorbent materials and medical textiles.
The fibers used in the production of non-woven fabrics are mainly polypropylene (PP) and polyester (PET). In addition, there are nylon (PA), viscose fiber, acrylic fiber, polyethylene fiber (HDPE), and chlorine fiber (PVC). According to application requirements, non-woven fabrics are divided into two categories: disposable application type and durable type.
There are also many types of non-woven fabrics, which can be divided into spunlace non-woven fabrics, needle-punched non-woven fabrics, printed non-woven fabrics, coated non-woven fabrics, pp non-woven fabrics, and polyester non-woven fabrics according to different processing materials and material components. Woven fabrics and other non-woven fabrics. According to different application fields, it is divided into agricultural non-woven fabrics, medical non-woven fabrics, clothing non-woven fabrics, industrial non-woven fabrics, etc. Generally speaking, non-woven fabrics are made of different material components!
