双分梳转杯纺渐变纱的设计与开发OA

To develop gradient-colored yarns with continuous and soft color transition,a systematic exploration was conducted based on dual-opening rotor spinning technology.Two different colored fiber slivers were fed into two separate feeding systems,the proportion and length of the two fiber types in the yarn were precisely controlled,a continuous color changing yarn was formed.Trial spinning and weaving were carried out using colored viscose and dope-dyed polyester.The knitted fabrics exhibited clear texture and color distribution,along with strong reproducibility.Additionally,the possibility of developing full-fashioned gradient-colored sweaters was explored through a reverse design model based on"sweater design-yarn design-sweater production".Practice demonstrated that it is feasible in technology for producing gradient-colored yarns using dual-openning rotor spinning technology.It is considered that the developed gradient-colored yarns based on dual-opening rotor spinning technology offer advantages such as excellent fiber blending,soft color transitions and consistent control over color and length,which is helpful to meet the diverse demands of the fabric market.
