摘　　要：使用氨纶(聚氨酯弹性纤维)来生产涤纶弹性混纺针织物时,通常会出现氨纶沾色、浮色难以清除,高温定形后上染率下降、分散染料迁移、色变等难题。采用最新分散染料可染高色牢度聚烯烃弹性纤维570X型号梦丝®代替传统氨纶生产高色牢度涤纶弹性混纺针织物,再配合聚烯烃弹性材料固有的化学特性即低温定形后相互粘连成网、化学惰性、耐强酸强碱,既提升了涤纶弹性针织物的内在品质,又实现了绿色环保、低碳低成本、简单高效生产,解决了长期困扰相关印染生产企业及下游用户的难题。When using spandex(polyurethane elastic fiber)to produce elastic polyester blended knitted fabric,it usually faces the problems of spandex staining,floating color cleaning,dye-uptake decreases,disperse dye migration and color change after high-temperature setting.High color fastness elastic polyester blended knitted fabric is produced by using the latest disperse dye dyeable polyolefin elastic fiber 570X type MENS®instead of traditional spandex.It makes use of the inherent chemical properties of polyolefin elastic materials:interfiber bonding to form a net after heat setting,chemical inertia,strong acid and alkali resistance.It not only improves the intrinsic quality of elastic polyester knitted fabrics,but also realizes green environmental protection,low carbon and low cost,simple and efficient production,and solves the long-term problems of related printing and dyeing enterprises and downstream users.
