Abstract: This paper puts forward outstanding features of polyurethane rubber covered roller through the analysis on cost performance of polyurethane rubber covered roller and butadiene-acrylonitrile rubber covered roller. In allusion to technical bottlenecks for the failure of large-scale application of polyurethane rubber covered roller in textile field, Rejeper Polyurethane has achieved systematic innovation and breakthrough in automatic manufacturing of rubber covered roller, performance optimization and rubber covered roller application. This paper points out disadvantages of traditional rubber covered roller in current compact spinning and compact siro spinning. Under the current trend of high-speed, high-yield and large-quantity spinning technology, polyurethane rubber covered roller adapts to the development of textile technology, provides high-quality new accessories of spinning and drafting for the transformation of textile industry from extensive to intensive operation modes and is good for energy conservation and consumption reduction of textile enterprises and the improvement of spinning quality.
