【摘 要】
：
为更好地筛选适用于超临界二氧化碳(ScCO2)流体染色的分散染料,使用状态方程结合基团贡献法和计算化学法,得到不同工况条件及不同染料结构对分散染料在超临界CO2流体中溶解度的影响规律,建立了分散染料在超临界CO2流体中溶解度预测方法.结果表明:不同工况条件会影响分散蓝79染料的溶解度,其中较低的温度和较高的压力对溶解过程更有利;从分子结构来看,蒽醌染料分子平面性更好,有利于 π-π堆积,故蒽醌类分散染料在超临界CO2流体中的溶解度比偶氮染料更低;降低染料内部分子间相互作用或提高染料与ScCO2流体间相互作

针对军训服每年产生大量的废弃,造成原料涤纶/棉混纺织物浪费的状况,将醋酸锌、尿素、尿素-醋酸锌共晶体系作为催化剂,通过乙二醇醇解法对废旧涤纶/棉混纺军训服中的涤纶组分进行解聚回收,并通过酸解法对棉纤维素组分进行回收;研究了催化剂种类、催化剂用量、反应温度和时间对废旧涤纶/棉混纺军训服、白色涤纶/棉混纺织物、白色涤纶织物醇解的影响;最后采用红外光谱仪、核磁共振波谱仪、差示扫描量热仪对醇解得到的对苯二甲酸乙二醇酯单体及酸解纤维素进行表征.结果表明:选用醋酸锌作为催化剂,催化剂相对用量为0.6％,反应固液比为1
为减轻纺织服装业带来的环境污染问题,促进服装绿色消费,对国家层面发布的绿色消费政策分布领域进行梳理,通过三级编码提炼出绿色产品、绿色技术、绿色价值链、绿色消费教育、绿色消费激励、绿色消费主体、分享、回收和循环9个分析维度,并从绿色产品供给、绿色消费策略、绿色消费模式3个层面对绿色消费政策实施进行阐释.研究发现:绿色消费政策集中于产品生产和回收处理阶段,主要涉及生活用品及服务、交通与通信领域,对服装领域关注不足;国家发展改革委、生态环境部、财政部和商务部发布的绿色消费政策较多;经研究提出,服装生产企业应该通
为提高淀粉浆料的使用性能,为纺织经纱上浆提供新型接枝淀粉浆料品种,以丙烯酸(AA)和丙烯酸丁酯(BA)为接枝单体,2-溴异丁酯化淀粉(BBES)为大分子引发剂,利用电子转移活化再生催化剂原子转移自由基聚合技术成功制备了双亲两嵌段接枝淀粉[BBES-g-(PAA-b-PBA)].以酸解淀粉、BBES为对比样,探讨了双亲两嵌段接枝支链的引入对淀粉浆液性能、浆膜力学性能的影响.结果表明:接枝支链的引入能够进一步增加淀粉浆液的黏度热稳定性、黏附性及其浆膜的断裂伸长率;随着AA接枝率的降低及同时BA接枝率的增加,淀
