Production of Phosphorus modified Flame Retardant Viscose Siro Yarn

LI Minglie LI Xiaomin YANG Xueqin YE Xiaoli

Abstract The spinning key points of Phosphorusmodified Flame retardant viscose 14.6 tex siro yarn were discussed.The relative humidity of picking process was focused and well controlled in order to reduce the generation of static electricity.In carding process,the coordination and management of each part such as licker in,cylinder,flat and doff were strengthened to improve the fiber carding and reduce the fiber injury.In drawing process,the silver output speed was decreased and the cleaning work for the channel was well done.In roving process,the differences of roving elongation were well controlled.Siro spinning was adopted.The parameters of electrical cleaning were optimized.By taking a serial of processing optimization measures,the problems of Phosphorus modified Flame retardant viscose fiber as easier generation of static electricity,lower strength,properties of loose and easily blocking up,easier generation of hairiness and so on were overcome.The Phosphorusmodified Flame retardant viscose 14.6 tex siro yarn produced has excellent quality indexes.It can meet the weaving requirement of following process.
