Description

变色皮革的生产工艺
技术领域
 本发明涉及一种变色皮革的生产工艺。
背景技术
人造皮革也叫仿皮或胶皮，是PVC和PU等人造材料的总称。它是在纺织布基或无纺布基上，由各种不同配方的 PVC 和 PU 等发泡或覆膜加工制作而成，可以根据不同强度、耐磨度、耐寒度和色彩、光泽、花纹图案等要求加工制成，具有花色品种繁多、防水性能好、边幅整齐、利用率高和价格相对真皮便宜的特点。
现在，人造皮革已被大量制造并应用在包括衣物、鞋子、家具及车辆用材料中。人造皮革的制造一般是使用由一般纤维、超细纤维或一般纤维与超细纤维混结成的不织布作为基布，并在该基布表面上填入聚氨酯树脂组成物，后施以研磨加工或压纹加工或以离型纸涂布聚氨基甲酸酯树脂施以贴合加工，而构成表面具有弹性及真皮纹路的皮料。
PU皮革就是聚氨酯成份的表皮.现在广泛适用于做箱包、服装、鞋、车辆和家具的装饰，它已日益得到市场的肯定，其应用范围之广，数量之大，品种之多，是传统的天然皮革无法满足的。变色皮革是用变色树脂添加进皮革的PU面层和BASE层，经过浸润，再后加工进行离型纸贴面或者压纹、印刷而制成，样式比较单一。
发明内容
本发明的目的是为了克服以上的不足，提供一种颜色多元化的变色皮革的生产工艺。
本发明的目的通过以下技术方案来实现：一种变色皮革的生产工艺，包括以下步骤：
A、制备基布；布料通过放卷机实现自动上料，并将该基布放入烘烤装置中预热处理；
B、在基布外层涂覆一层聚氨酯粘合剂，形成粘合层；
C、在粘合层上涂覆一层PVC发泡层；
D、在PVC发泡层上涂覆一层表面处理剂，待所述表面处理剂干固后形成一PVC面层；
E、在PVC面层的表面涂覆一层水溶性树脂和一种或多种色料，形成水溶性树脂层；
F、用擦拭水擦拭水溶性树脂层，形成局部变色。
本发明的进一步改进在于：步骤A中基布直接由满足家具、手袋或服装类皮革需求的布料或湿式底胚制备而成。
本发明的进一步改进在于：步骤A中基布包括布料层、湿式底胚或发泡底胚之一。
本发明的进一步改进在于：以擦拭方式对基布上的顶层面进行接触磨除加工处理。
本发明的进一步改进在于：表面处理剂以合成树脂为原料。
本发明的进一步改进在于：表面处理剂为擦拭处理剂或擦焦处理剂。
本发明的进一步改进在于：热塑性弹性体是一种具有橡胶的高弹性、高强度、高回弹性、具有可注塑加工的特征的材料。
本发明与现有技术相比具有以下优点：
本发明通过擦拭水擦拭水溶性树脂层来达到皮革的局部变色效果，颜色可以多元化搭配，实用性更广；水溶性树脂为水溶性树脂，可与水任意比例相溶，且粘度低、固含量高、气味小，具有良好的流平性；水溶性树脂聚合所采用溶剂均采用无毒的高挥发性溶剂，安全环保。
