Draw Winding for Industrial and Technical Yarns
topic
Industrial yarn draw winding produces high-tenacity polyester yarns at 6 to 9 centiNewtons per decitex for tyre cord, conveyor belt reinforcement, and geogrid applications through high draw ratio processing at 2.5 to 3.5 combined with relaxation annealing that achieves the optimum combination of tenacity, dimensional stability, and adhesion to rubber matrices required for technical reinforcement applications at yarn counts of 550 to 2200 decitex.
Role
Produces the high-tenacity fully drawn industrial yarns used for mechanical rubber goods reinforcement, geosynthetic reinforcement, and technical rope through draw winding processes optimised for maximum tenacity development at high draw ratios that sacrifice elongation for strength, with industrial yarn draw winding being distinct from apparel yarn processing in its priority on maximum tenacity and thermal stability over the softness and drape considerations of apparel yarn production.
