在聚氨酯胶料中掺杂感光变色粒子和凹土粒子,采用间接涂层工艺,在细旦尼锦纶尼丝纺基布上开发感光变色防紫外面料。对基布和胶料的选择、制备工艺,OPP膜上胶、贴合和熟成工艺进行了详细介绍,并对所开发的产品进行了感光变色、防紫外和物理性能的检测。结果表明,采用该工艺开发的面料能满足人们对服装的感光变色个性化和防紫外功能性的需求。
A new kind of photochromic fabric with anti-UV property is prepared by coating photochromic dopped polyurethane adhesive and attapulgite particles onto thin light nylon taffeta with indirect coating method, The base cloth and adhesive are carefully selected and the processing technology of oriented poypropylene (OPP) film coating, laminating and ripening are discussed. The photochromic, anti-UV and physical properties of the products are tested. The results show that the product can meet the requirements for personalized photochromic and anti-UV property,
