络筒工艺对聚酯超临界CO2无水染色性能的影响
Influence of winding process on supercritical CO2 waterless dyeing performance of polyester
摘要
Abstract
To address the problems of uneven dyeing and large water consumption in conventional aqueous dyeing of polyester cone yarn,polyester cone yarn was waterless dyed in supercritical CO2 system with disperse orange 30.The effects of winding tension,winding angle and cone yarn mass on the apparent color depth of the yarn were investigated.The surface morphology,hydrophilicity,and mechanical properties of the dyed yarn were characterized by scanning electron microscopy,contact angle measurement,and electronic universal testing.The results showed that with increasing winding tension,the color depth values of the inner,middle,and outer layers of the cheese yarn were firstly decreased and then increased.The optimal process parameters were determined to be a winding tension of 3.0 cN,a winding angle of 65°,and a cone yarn mass of 850 g.Under these conditions,the soaping fastness and rubbing fastness of the dyed yarn reached grade of 4-5,and the light fastness reached grade of 4.In addition,a small amount of dye particles was observed on the surface of yarn after dyeing,while both of hydrophilic and mechanical properties of the yarn were enhanced.The optimized winding process significantly enhanced the permeability and dyeing uniformity of polyester cone yarn in supercritical CO2 fluid.关键词
