Description

一种工业用布的生产工艺
技术领域
本发明属于工业用布技术领域,涉及一种工业用布,具体是一种工业用布的生产工艺。
背景技术
工业用布种类繁多,根据材料和用途的不同大致分为丙纶滤布、除尘滤袋、单丝滤布、无纺滤布等,工业用布需要耐酸碱、耐磨、导电性良好等特点,近年来,高性能的新型合成材料的出现,使得工业用帆布材料的发展速度加快,但如何进一步提高工业用布的性能,却一直是个困难的课题。传统浸胶体系中采用RFL浸胶液,即间苯二酚—甲醛—胶乳浸渍体系,再加入异氰酸酯为交联剂。由于聚酯的内聚能密度不像RF树脂,RFL浸胶液与聚酯相之间的分子接触性差。而且间苯二酚在高温环境下易挥发,不仅降低了浸渍液的浓度,对车间工人危害较大。因此必须改进现有浸胶体系,提高工业用布的性能,减少有毒物质的释放。
发明内容
本发明的目的在于提供一种工业用布的生产工艺。
本发明的目的可以通过以下技术方案实现:

(2)将步骤(1)得到的经纱与纬纱混合,合并后片纱浸入浸渍液,再将湿浆纱分绞进入热烘干区,热风烘干纱线表面成膜后,进入锡林烘干,锡林烘干至含水率2.5-3%,并轴织成坯布;
(3)将步骤(2)得到的坯布进入脱浆机,进行第一次热清洗,脱浆机将坯布上的含水率降至1-1.5%;
(4)将第一次热清洗后的坯布放入闷炉进行第二次热清洗,使含水率降至0.6-0.8%;
(5)将第二次热清洗后的坯布通过表面处理机,涂覆硅烷偶联剂,经烘干、切边,按等级包装入库。
步骤(3)所述的第一次热清洗温度为150-250℃,步骤(4)所述第二次热清洗炉温为440-460℃,闷烧时间为24-48h。
所述硅烷偶联剂浓度为4.5-6.5%。
所述浸渍液由天然乳胶20-25份、聚乙烯醇6-8份、渗透剂2-4份、PH调节剂1-2份、抗氧化剂0.4-0.8份、水55-65份、丁苯胶乳15-20份、醇醚12-16份、杀菌剂4-6份、聚丙烯酰胺35-40份、分散剂1-3份、硅油1-2份制成。
