What is the material composition of non-woven fabrics? Non-woven products are different from general textiles in terms of material composition. In order to ensure the excellent air permeability and flexibility of nonwoven fabric
and improve the stretchability and quality of non-woven fabrics, non-woven fabrics are The material composition of cloth is very different from general textiles! Non-woven fabrics are mostly made of polypropylene (pp material) pellets as raw materials, which are melted at high temperature, spinned, laid out, and hot-pressed in one continuous step. produced by law.
The top three fibers used in nonwoven production are polypropylene (62% of the total), polyester (24% of the total) and viscose (8% of the total). Between 1970 and 1985, viscose fibers were used the most in the production of non-woven fabrics. However, in the past five years, in the field of sanitary absorbent materials and medical textiles, the application of polypropylene fibers and polyester fibers has begun to dominate. The fibers used in the production of non-woven fabrics are mainly polypropylene (PP) and polyester (PET). In addition, there are nylon (PA), viscose, acrylic, ethylene (HDPE), and vinyl (PVC).
According to application requirements, non-woven fabrics are divided into two categories: disposable application type and durable type. To sum up, there are many materials and components for processing and making non-woven fabrics, which are mainly distinguished by what they are used for. Here I will briefly explain, the materials are polyester, polypropylene, aramid, acrylic, nylon, composite, ES, 6080, vinylon, spandex, etc. I said they are all fibers. Non-woven fabrics produced by different materials and different processes have great differences in sales prices.
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, laminated non-woven fabrics, pp non-woven fabrics, and polyester non-woven fabrics according to the different processing materials and material components. Various types of 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.
