【摘要】 随着工业的发展,各种废气对大气的污染曰益加剧,导致地球臭氧层遭到破坏,地表太阳光的紫外线辐射量逐渐增强,对人们的健康造成了损害。因此,国际上非常重视抗紫外功能性织物的开发和研究,纺织品的抗紫外整理成为纺织行业的重要课题之一。 本文针对提高涤、棉织物紫外线防护性能这一目标,选用合适的非离子及阴离子表面活性剂,分别通过乳化、分散的方法复配出了适合于纺织整理加工的新型紫外整理剂(UVS),并对其应用进行了系统的研究。本文选取了空隙率较小的涤纶织物以及棉织物,通过与目前整理效果较好的Rayosan P、Rayosan C、Tinofast PEX、Tinofast CEL等紫外吸收剂的一系列相关对比实验,筛选出了对涤纶整理效果较好的S-61和对棉整理效果较好的S-81。 在研究涤用抗紫外整理剂应用工艺时,通过抗紫外效果对比试验得出了合适的整理工艺,并且做了一系列上染率测试和耐久性试验;将整理剂与分散染料对涤纶同浴染色后,通过测定织物UPF值、K/S值、L、a~*、b~*值以及日晒牢度等指标,讨论了整理剂对涤纶的处理效果和对分散染料的影响。结果表明S-61在合适的工艺条件下对涤纶上染率很高,提升性很好,类似于分散染料对涤纶的上染,可以与分散染料同浴上染涤纶。此外,将整理剂与荧光增白剂对涤纶同浴处理更多还原

【Abstract】 With the development of industry, pollution for atmosphere has become increasingly serious and ozone layer has been destroyed. Because the increased amount of radiation of ultraviolet in the sunlight is harmful to people’s health, the research of ultraviolet protective textile attracts more and more worldwide attention.This research is focused on improving ultraviolet protective ability of polyester and cotton. The surfactants which have good ability of dispersion and emulsification have been selected to compound several different kinds of ultraviolet absorbers. The attempt is made to study the new kinds of UV absorbers (UVS) and to select out S-61(a better UV absorbers on polyester fiber) and S-81(a preferred UV absorbers on cotton) from several newly absorbers together with Rayosan P, Rayosan C, Tinofast PEX, Tinofast CEL, which perform outstandingly in UV protection being used now through a series of comparison experiments.In the study of application of UV absorbers for Polyester fiber, the absorbers are applied to polyester dyeing together with disperse dyes by one-bath dyeing methods. The influence on polyester treatment and dispersed dyes used is discussed on the data of UPF, K/S, L, a~*, b~* and light fastness. The result shows that S-61 is best applied on polyester and with no adverse effects on dispersed dyes. In this paper, the treatment of UV absorbers and fluorescent whitening agents is applied simultaneously in one bath. UPF and whiteness show that all the used absorbers have some slightly influence on whitening treatment.In the study of application of cotton UV protection treatment, the best padding and curing process of S-81 is attained by controlling pH, temperature, bath-rate and agents. The result is that S-81 can react with cellulose fiber in 100℃ and the bath-rate of 1:10. At the same time, it is also suitable for pad-bake process. Its influence on the degree of white is fairly low. The application of S-61 and S-81 may have promising future.Jianning Wang(Textile Chemistry and Dyeing&Finishing Engineering)Supervised by professor Quan Zhu and professor Xiaoli Chen更多还原
