为进一步改善以分散染料蓝72为主的系列颜色耐光稳定性差的问题,通过热升华的方式将分散染料蓝72/紫外线吸收剂同浆印花,将紫外线吸收剂与分散染料同步转移至涤纶织物上,在提高织物耐光稳定性的同时,减少工序、降低能耗。通过对常用紫外线吸收剂的筛选、紫外线吸收剂分散液的制备和分散染料蓝72/紫外线吸收剂同浆印花织物抗紫外线性能的研究,探究转移温度、时间对印花织物耐光稳定性的影响。结果表明:紫外线吸收剂UV-326的抗紫外线效果较好;当UV-326分散工艺参数为:分散剂质量分数为UV-326的3%、氧化锆珠尺寸选用0.3~0.4 mm、UV-326与氧化锆珠的质量比为1∶10、分散时间为18 h;转印工艺为:转印温度230℃、转印时间10 s; UV-326用量质量分数达到6%时,转移印花织物的耐光色牢度可提高1~2级,涤纶分散染料转移印花织物的耐光稳定性有了明显提升。 相似文献

为改善染色涤纶织物的耐光色牢度,制备了具有紫外线吸收剂性能的邻羟基苯基均三嗪结构的化合物2-(2′,4′-二羟基苯基)-4,6-二(2′,4′-二甲基苯基)-1,3,5-均三嗪。采用高温高压染色方法将此紫外线吸收剂上染到涤纶织物上,测试其对涤纶的上染性能和改善涤纶织物耐光色牢度的作用。结果表明:自制紫外线吸收剂在高温高压条件下对涤纶纤维具有较高的上染能力,无论单独还是与分散染料同浴上染,都能显著提高织物的紫外线防护性能;该紫外线吸收剂单独上染的涤纶织物光致泛黄程度降低,与分散染料同浴上染能一定程度地改善染色涤纶织物的耐光色牢度。 相似文献

为提升羊毛织物的白度,同时延缓其光黄变速率,采用氧化漂白和氧化/还原联合漂白工艺对其进行处理,并将漂白羊毛进行紫外线光照实验,测试其光黄变历程,探讨了漂白工艺对羊毛形貌与光稳定性能的影响;采用紫外线吸收剂UVFW对羊毛进行整理,分析了UVFW整理对其耐光稳定性能的影响。结果表明:漂白工艺在提升羊毛白度的同时,将加速其光黄变速率,同时加剧其光脆损程度;经1%(o.w.f)UVFW整理后,联合漂白处理的羊毛织物表现出较高的耐光稳定性能,光照6 h白度仍高于氧漂羊毛织物,其原因在于联合漂白羊毛在获得较高起始白度的同时,羊毛纤维表面具有更高的表面润湿与吸附能力,有利于UVFW的吸附和扩散。 相似文献

光稳定剂是一种能够在一定程度上延缓或者抑制光化学作用引发材料降解的助剂,其也可以非常有效地减缓染料光损伤。就目前而言,利用经过均匀分散后的光稳定剂对染料进行掺加,可以显著提升织物的抗紫外性能以及耐光色牢度。本文选择了几种紫外线吸收剂以及受阻胺光稳定剂,针对其在涤纶超细纤维织物染色工艺中的性能以及耐光色牢度的影响进行了研究和讨论。 相似文献

活性染料染色耐光色牢度的影响因素分析 总被引:3,自引:1,他引:3
分析了活性染料品种、染色浓度、拼色、布面pH值对棉织物耐光色牢度的影响,包括日晒牢度、汗光牢度;探讨了耐光色牢度提升剂对活性染料染浅色织物耐光色牢度的提升作用;研究了多种功能整理,如柔软、防皱、纳米防水防油和提高耐氯牢度整理,对浅色织物耐光色牢度和对耐光色牢度提升剂应用效果的影响。结果表明,不同染料品种的耐光色牢度不同,浅色织物的耐光色牢度通常较深色织物低,拼色光牢度由其中耐光色牢度最差的染料决定;耐光色牢度提升剂对浅色织物耐光色牢度有很大的提升作用,并可与其它功能整理剂同浴整理。 相似文献

A new approach to simultaneous functional finishing and reactive dyeing of polyamide‐6–cotton fabric (50/50) is developed. The extent of improvement in the functional and dyeing properties is determined by the UV‐absorber, UV‐Sun® CEL, concentration, type and concentration of the used reactive dye as well as the treatment sequence. The UV‐protection and the antibacterial properties, against S. aureus (G+ve) and E. coli (G?ve) bacteria, of the simultaneously finished and dyed fabric samples are maintained even after 15 washing cycles. After 15 washing cycles, the depth of shades and the fastness properties of the obtained dyeings are not seriously affected. The incorporation of the used UV‐absorber onto the blend fibres was also confirmed by SEM analysis. 相似文献

Cattle hoof and horn keratin hydrolysate from cattle hoofs and horns were successfully extracted and used to cationize cotton fabric. The effect of cationization was tested by dyeing the cationized cotton fabric using reactive dyes (cationized sample). The results were compared to conventionally dyed cotton fabric sample without cationization. The UV/VIS absorption result showed 6% improvement in exhaustion; the Color Eye K/S result gave 4.5% improvement in fixation and 6.8% in dye utilization for reactive dye (H-Reactive Red). Acceptable color fastness to washing (4/5) and light fastness (7) were achieved on cationized sample. 相似文献

Application of natural dyes has increased interest in the past few years due to the eco-friendly behavior of these dyes. The present research is concerned with the effect of UV on dyeing behavior of cotton using marigold as source of natural Lutein dye. This is colorant lutein which imparts greenish yellow color to cotton fabric. The dye powder and cotton fabric were exposed to UV-radiation for different time intervals prior to dyeing and dyeing was performed at different dyeing variables. International Standard Organization (ISO) methods were employed to evaluate the color fastness properties, such as color fastness to light, washing and rubbing. It is found that 90 min exposure of UV radiations was the optimum condition for surface modification and dyeing of 70 min at 40°C give excellent results using 4 g/L salt to achieve maximum exhaustion. For improvement of color fastness, tannic acid (8%) as pre- and 6% as post-mordant is the best condition. It is found that UV ray treatment can be used to other fabrics followed by dyeing using extracts of dye yielding plants without any physical characteristics damage. 相似文献
