Why Polyurethane Rubber soft disc are better than ceramic or plasma coated hard disc ?
• Offers much higher amount of friction therefore more twist. • Softness of PU rubber leads to minimal fiber abrasion and therefore generation of fluff stuff, also known as snow, is prevented during processing. • Its has better texturing ability and imparts better characteristics like desired bulk, loft and stretch in the yarn. While PU friction discs have certain advantage over other hard discs, certain special characteristics of JSH brand pu discs makes it the first choice for texturisers around the world. JSH friction PU disc has following special properties: • Very high wear resistance against high speed rotation due to appropriate grade of polyol and isocynate. • Addition of certain additives makes it more oil resistant, high temperature resistant and safe against electrostatic charge build up. • 100 % piece to piece dimensional accuracy allows texturisers to have accurate yarn angle while moving through the friction unit. • Uniformity and perfection in surface finish of JSH disc
