Silk has always been a highly prized fiber because of the smooth, lustrous, soft fabrics made from it; it has always been expensive and comparatively scarce. It was, therefore, logical for man to try to duplicate silk. Rayon was the first man-made fiber. Rayon was produced in filament until the early 1930s when an enterprising textile worker discovered that the broken and wasted rayon filaments could be used as staple fiber. Acetate and nylon were also introduced as filaments be used as silklike fibers.<br />Many man-made fibers were produced in the first half of the twentieth century and from that time onward tremendous advances have been made in the man-made fiber industry, primarily modifications of properties for specific end uses.<br /> Of many fibers, those that are most widely used are wool, cotton, flax, silk, viscose, polyester fiber, nylon and Acrylic fiber. <img src="images/smilies/smile.gif" smilieid="1" border="0" alt="" /> |
