What raw materials are required for processing non-woven fabrics? The quality of spunlace nonwoven fabric
raw materials has an important impact on the quality of non-woven fabrics. Therefore, it is necessary to strictly control the quality of raw materials when producing and processing non-woven fabrics to avoid non-woven fabric processing. Inferior raw materials are used.Printed Mask Spunlace Nonwoven Fabric Roll Goods
Non-woven fabrics mostly use polypropylene (pp material) pellets as raw materials, and are produced by continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing and coiling. 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.
Needle-punched non-woven fabrics are made of fibers and can be produced by mixing a variety of fibers. Commonly used raw materials are polyester fibers, viscose fibers, polypropylene fibers, etc.; spunlace fabrics are generally mixed with polyester fibers and viscose fibers; spunbond nonwovens The cloth mostly uses polypropylene (pp material) pellets as the raw material; the meltblown cloth mainly uses polypropylene as the main raw material.
There are many materials of 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. The sales price of non-woven fabrics produced by different materials and different processes varies greatly.
