地球表面太阳紫外线辐射的增加,导致人类皮肤发病率不断上升,严重地影响了人体健康,有资料显示,臭氧层每减少1%,紫外线辐射强度就增大2%,患皮肤癌的可能性将提高3%,自然界中紫外线量随时间和季节而变化,夏季太阳直射时紫外线辐射量达到最大,容易造成过量紫外线的照射而使人体皮肤受到伤害,这时做好紫外线防护工作尤为重要;因此,开发抗紫外线纺织品,有效保护人体免受过量紫外线辐射很有必要。
发明内容
针对上述问题,本发明旨在提供一种抗紫外线纺织品的染色方法。
本发明通过以下技术方案实现:
一种抗紫外线纺织品的染色方法,具体方法如下:

(2)将经步骤(1)处理后的纺织品浸没于染色剂中浸泡24~28min并不断搅拌,滤剂取出,真空处理14~16min,浸没于亚麻籽胶水溶液中浸泡18~20min并通入功率为96~100W、频率为135~140kHz的超声波进行超声处理;
所述的染色剂,由以下重量份的原料制成:五水偏硅酸钠5.4~5.8份、酒石酸钾7.2~7.6份、玉米淀粉3.5~3.9份、氧化铁蓝9.4~9.8份、蔗糖脂肪酸酯4.4~4.6份、硅藻土5.1~5.5份、去离子水54~58份;
(3)将经步骤(2)处理后的纺织品置入温度为-6~-4℃的冷冻箱内恒温冷冻17~19min,取出,置入温度为110~115℃、压力为0.24~0.28MPa的条件下热压干燥至无水分。
作为发明进一步的方案:步骤(1)所述的绿原酸水溶液的质量分数为1.5%~1.7%。
作为发明进一步的方案:步骤(2)所述的真空处理,先在温度为67~71℃、真空度为190~210Pa的条件下真空处理5~6min,然后在温度为55~59℃、真空度为340~360Pa的条件下真空处理9~10min。
作为发明进一步的方案:步骤(2)所述的亚麻籽胶水溶液的质量分数为2.2%~2.4%。
本发明的有益效果:本发明提供的一种抗紫外线纺织品的染色方法,不但能够有效降低紫外线透过率,增强对光的反射和吸收,能够强烈吸收紫外线,并将高能量的紫外线转变成低能量的热能或波长较短的电磁波释放出来,从而起到抗紫外线的作用,提高其抗紫外线能力,防护效果越好,屏蔽效率高,抗紫外线功能性稳定持久,而且安全无毒,不刺激皮肤或引起过敏反应,染色效果好,固着性好,不易褪色,耐水洗和干洗,对光、热和化学物质稳定。
