拥有柔软、不掉色，同时抗起毛起球的绒衣、大衣，是每个人对冬季着装既简单又奢侈的要求? Among the second prize projects of the National Technology Invention Award in 2014, there is an invention that sounds quite awkward and professional – the new copolyester MCDP continuous polymerization, spinning and dyeing and finishing technology, which can be used to produce products that meet the above conditions. The energy-saving and environmentally friendly “magic fabric” can help us realize this small but long-term elusive clothing wish. ?</p
This project was jointly completed by Donghua University and Shanghai Lianji Synthetic Fiber. Project leader Gu Lixia, a professor at Donghua University who has been engaged in chemical fiber research for a long time, introduced that my country’s annual output of polyester fiber reaches 40 million tons, accounting for 70% of the world’s total. More than %, large-capacity continuous polymerization melt direct spinning polyester production capacity has exceeded 2/3 of the total, and most of them produce conventional polyester fibers. ?聚酯大多是半刚性大分子结构，纤维结构紧密，染色性和触感均较差? ?改进纤维的染色性是聚酯纤维功能化的重要方向，一直存在聚合难以控制的难题，织物需要碱减量处理，能耗和排放瓶颈问题没有解决，严重影响聚酯纤维改性技术的推广应用? ?其中，我国聚酯纤维同质同构化严重，转型升级困难，亟须解决大容量功能化聚酯连续聚合关键技术? ?</p
新型共聚酯惭颁顿笔连续聚合、纺丝及染整技术解决了聚酯同质同构化问题，突破了聚酯生产能耗和排放瓶颈。这一项目研制的“超柔软易染聚酯纤维产物”具备常压沸染、不需碱处理的低碳环保特性，超柔软手感、吸湿性良好和抗起毛起球性能显着等仿棉功效。
在顾利霞看来，此项发明的另一个重大意义在于节能环保? This aspect refers to the fact that new polyester products use low-temperature reactions in polyester synthesis. Compared with the high-temperature reaction requirements of original polyester products, energy consumption is reduced to a certain extent. In the spinning process, regardless of the drying temperature , spinning temperature and heating temperature should be lower than conventional polyester ?特别在染整过程中，新型聚酯产物采用常压沸染工艺，无需碱减量处理工序? ?</p
另一方面则是指新型聚酯产物可以用于仿羊绒工艺当中。顾利霞介绍，羊绒稀少而昂贵，市场上即使是号称“全羊绒”的大衣，也往往只有10%的羊绒含量。生产羊绒涉及山羊养殖业，由于山羊啃过的草地较难恢复生长，长久以来羊绒制造业带来了不小的环境保护问题。而新型聚酯制成的纤维材料相当柔软，和羊绒混纺后在手感和舒适度上和纯羊绒极为相似，因此仿羊绒工艺不但能降低羊绒制品的价格，还有利于保护草地。
新型共聚酯技术的产业化也获得了极大成功，近日一家公司还主动找到顾利霞，希望能将新型聚酯制成的纤维材料用在仿羊绒面料的制作上? ?顾利霞答应了合作要求，即将进行这方面的研发，估计将耗时几个月时间? ?此前，新型聚酯产物已经被成功地用于制作羊绒衫的仿羊绒工艺当中? ?据悉，早在2006年，顾利霞和她的团队就开始着手准备研发这一问题? ?2009年时，在列入国家“十一五”科技支撑计划后，这一课题正式启动，终于2013年完成并通过了验收? ?现在，这一项目已申请中国发明专利10项，申请国际发明专利3项? ?在2014年之前，这一技术就已创汇909.6万美元?
