Staining Characteristics of Polyethylene Fiber with Side Chain Crystalline Block Copolymer

Abstract

Polyethylene ( PE ) is known as the typical plastic whose surface properties are very dif fi cult to modify and it is believed that it is impossible to modify the surface properties chemically. However, recently, Yao had clearly shown that side chain crystalline block copolymer ( SCCBC ) has an ability to modify the PE surface property chemically. In this study, by using the SCCBC, we had tried to stain the very high molecular weight PE fi ber that is known to be the most dif fi cult product with respect to modifying the surface property, not only chemically but also physically. From the results, the high molecular weight PE fi ber can be dyed by using the SCCBC and it had shown very high durability. This study shows that the application area of SCCBC is very wide and useful.
