摘　　要：聚乳酸(PLA)纤维是一种绿色环保的聚合高分子材料,开发PLA纤维产品已成为当今生态纺织产品的开发方向之一。以PLA纤维为原料,纬编毛巾组织为基础,采用小元宝针织结构,在大圆机上编织、气流染色机上染色,制备了一种双面剪毛绒针织面料。介绍了PLA双面剪毛绒面料的特点和生产工艺,阐述了该面料的织造、染色、还原清洗、拉毛、梳毛、剪毛和定型等工序及技术关键,以期为同类产品的开发提供参考。The PLA fiber is a natural recyclable polymer material in the 21st century,and the development and utilization of its products meet the current requirements of green,environmental protection and renewability.It has good social and economic value,which is conducive to the high-quality development of green textile technology in China.With PLA fibers as raw material,based on weft woven towel tissue,a knitted fabric with double-sided sheared plush was developed by weaving on a large circular knitting machine with a small ingot knitting structure.The PLA fabric with double-sided sheared plush has the advantages of fluffiness,warmth,breathability,softness,skin-friendliness,bacteriostasis,mildew-proofing,and zero irritation to human skin,so it is an ideal fiber fabric for clothing.To ensure that the fabric surface is smooth and without creases,and save water,dyeing materials,additives and energy,aits nd truly achieve energy saving,emission reduction,green and environmental protection,airflow dyeing machine should be used for printing and dyeing processing.For the PLA fabric with double-sided sheared plush strong alkali cannot be used in the process of washing and degreasing and dyeing,reduction and cleaning,otherwise serious hydrolysis of PLA fiber and strong damage of PLA fiber will occur,resulting in short hair,hair loss and other phenomena.In order to overcome the influence of reduction cleaning on PLA fiber damage and its color depth under strong alkali conditions,it is advisable to use the process of low temperature reduction cleaning of soda ash fuse powder twice,and the ideal color fastness can be obtained.PLA double-sided shearing plush should be dried directly with hot air from the needle board of the stenter machine,which can prevent local hardening of the fabric,hardening of the hand and other phenomena at local high temperature during contact drying.In the process of brushing,combing and shearing of PLA fabric with double-sided shearing plush,the process parameters need to be reasonably adjusted according to
