双分梳转杯混纺纱结构表征OA

An additional feeding and opening unit were incorporated in dual opening rotor process,independent feeding of two slivers and their blending in the spinning process were achieved.To investigate the structural characteristics of dual opening rotor blended yarn,black viscose slivers and white viscose slivers were selected as raw materials and spun the blended yarns with blending ratios of black to white were 10∶90,7∶93,5∶95 and 0.7∶99.3,respectively.Tracer fiber method was combined with digital image processing technology,the surface structures and internal structures of the yarns were observed,the distribution patterns of fibers fed through different channels were explored.The test results indicated there were some structural similarities between dual opening rotor yarn and traditional rotor yarn,while it exhibited some differences in surface fiber distribution and internal fiber arrangement.For dual opening rotor yarn,the two different fibers showed a distinct alternating interval distribution on the yarn surface,and along the axial direction of the yarn,the fiber distribution exhibited a degree of randomness.Within the internal structure of the yarn,the number of hooked fibers were reduced in the dual opening rotor yarn,however,there were an increase in the number of wrapped fiber,folded fiber,looped fiber or bent fiber.The unique structure of dual opening rotor blended yarn offered a potential for the development of new types yarn products.
