Polyacrylonitrile fibers are synthetic fibers made from polyacrylonitrile or acrylonitrile copolymers. The second monomer is non-ionic monomer such as methyl acrylate, methyl methacrylate, etc. The third monomer
That means textiles are considered to be organic fibers that come from nature, like cotton, flax and wool, as well as synthetic (man-made) fibers. In a cave in Siberia, sewing needles dating to at least 50,000 years old have been discovered. Many other prehistoric needle specimens from ...
While linen is similar to cotton, it is made from fibers derived from the stems of the flax plant instead of the bolls that grow around cotton seeds. Garments made of linen are desirable in hot and humid climates. Unlike cotton, which tends to retain moisture for a significant period of...
