What is the raw material for the production of non-woven fabric?

There are many types of fiber materials suitable for non-woven fabrics, mainly natural fibers and chemical fibers. In order to produce nonwovens of different properties, uses and styles, high performance specialty fibers and functionalized, differentiated fibers can also be used. String 1
(1) Natural fibers: such as cotton, wool, hemp, silk, etc.;
(2) Chemical fiber: such as viscose fiber, polyester, nylon, polypropylene, acrylic, vinylon, etc.;
(3) Differentiated fibers and high-performance fibers;
Such as: low melting point thermal bonding fibers (ES fiber, modified polypropylene, copolyamide, copolyester, etc.);
Microfiber (denier than 0.3dtex);
Three-dimensional crimped hollow fiber;
Colored fiber
High performance fiber (carbon fiber, aramid, polyphenylene sulfide, polyether ketone, etc.);
Water-soluble fiber (water-soluble polyvinyl alcohol fiber, hydroxymethyl cellulose fiber, etc.)
