Structure and Properties of Novel Modified Polyester Fibers

Abstract:

The structure and properties of the fiber affect its processing and wearing performance of the textile product. There are 3 kinds of novel polyester fibers modified by copolymerization. To make good use of these modified polyester fibers and predict their processing and wearing performance, the structure and properties of the fibers were characterized by cross section, crystallinity, moisture regain, tensile test, DSC and TG. Results show that the 2 of the modified fibers are profiled fibers with lower crystallinity and higher moisture regain. The mechanical properties of the modified fibers are worse than that of the ordinary polyester, but much better than cotton fiber. The modified polyester fibers are more thermal sensitive than ordinary polyester fiber. The heat treatment temperature of them in the textile processing should be controlled more carefully than ordinary polyester fibers.
