随着纺织业技术的发展和纺织品趋向高档化、多功能化,对功能性复合化纤材料需求会日益增多。通过在纤维中添加一些助剂,可以增加纺织产品的附加性能。功能复合型化纤原料,在某种程度上具有“超前意识”,只有通过产品的宣传和使用者的应用才能估计比较确切的需求量。高附加值产品历来是引导市场的典范,当纳米级超细粉末工业化后,高附加值涤纶的品种就会不断推陈出新。涤纶的远红外产品、紫外线线屏蔽产品、“奇异产品”等都会有较大的发展空间。这类产品目前所要关注的是,尽可能适应纺织业和染整技术加工水平,完善纺织加工性能,稳定产品质量,降低产品成本,以吸引更多的使用者。由于人类释放的氟碳化合物使地球大气层中臭氧层的减少,到达地面的紫外线增加,臭氧层每减少1%皮肤癌的患病率将增加2. 3%,而普通面料制成的衣物紫外线遮挡系数只有5,远远小于紫外线防护的基本要求15。针对以上问题本科题研制了紫外线屏蔽剂前驱体、紫外线屏蔽聚酯,讨论了该聚酯的短纤纺丝工艺以及影响紫外线屏蔽面料性能的因素。1. 制备了硫酸钡悬浮液,并利用氨水、碳酸铵溶解了氧化锌;以硫酸钡为载体,通过加热使碱式碳酸锌负载到硫酸钡上,合成了紫外线屏蔽剂前驱体。通过透射电镜分析,硫酸钡粒径在20-25nm,紫外线屏蔽剂前驱体粒径在50-80nm。利用DTA对其分解温度进行了测试,其温度为272. 7℃。2. 通过调整加料工艺条件,控制聚合反应速度制备了紫外线屏蔽聚酯:含氧化锌1wt%0. 2mm的聚酯薄膜紫外线透过率为7%,电子扫描电镜可以看到其在聚酯中粒径为80-200nm。对所得聚酯进行流变性能分析,接近于一般聚酯。3. 对紫外线屏蔽聚酯进行了纺丝,通过控制纤度、拉伸比、纺速、泵供量、环吹、上油等工艺条件,实现了紫外线屏蔽纤维的生产。4. 使用紫外线屏蔽纤维制成的纱线织成布样,其紫外线平均透过率为5. 5%,UPF值为50+,达到了紫外线防护的效果。讨论了影响紫外线透过率的各种因素。山东大学硕士学位论文ABSTRACT Along with the develoPment of sPinning teehnieal,multi一允netions and toP gradebeeome the tendeney of textile fabries,and the needs of multi一fonetional fibermaterial are inereasing.Adding some funetional inorganie Partieulates into the fiberean apPend the use of fabrie.The extra一funetional fiber materials 90 beyond therealities of our eountry in some extent,o川y through advertisement and the use ofconsumer quantity ofthe need will be reliable,High Profit 15 the engine ofmarket,theindustrialization of nano一material will Push the fiber to get rid of the stale and bringforth the fresh.Infrared一terylene,UV-Proteetion fiber and marvelous Produets arePromising.Problems the Produets should bee岔e of are the eomPatibility relation ofthe fiber indust叮and the dyeing teehnic,Perfeeting the sPIlining ability, gainingstable quality, deereasing the eost,the eonsumers would inerease dramatieally if theseProblems have been solved.
