PROCESS FOR PRODUCING SOIL-REPELLENT AND ABRASION-RESISTANT MONOFILAMENTS AND THEIR USE

摘要

A process is disclosed for producing soil-repellent and abrasion-resistant monofilaments having 0.1 to 1.0 mm diammeter from a linear PET/polydialkylsiloxane, in which the Si component with 0.15 to 2.0 % by weight Si content is incorporated into the polymer chain. The soil-repellent and abrasionresistant monofilament has at least 36 cN/tex solidity, less than 44 % elongation relation to the non-elongated filament, and at the same time a soiling index lower than 10 after 5 soiling cycles. This monofilament is suitable for producing screening fabrics for paper machines, fishing lines and fishing nets.
