技术领域
本发明涉及一种涤棉双面胶粘合衬及其生产方法。
背景技术
常规粘合衬的一个面有粘合层，能与一块面料粘合在一起。有一些特殊品种服装或有特殊要求服装，要求粘合衬能把两块面料粘合在一起，获得较硬手感、较高剥离强力和其他性能。为此，研发和生产正反两面都有粘合层的涤棉双面胶粘合衬，满足服装行业需求。
发明内容
本发明目的在于提供一种性能优异、制备简便的涤棉双面胶粘合衬及其生产方法。
本发明的技术解决方案是：
一种涤棉双面胶粘合衬，其特征是：在涤棉基布的正反两面都有粘合层；经纬向干热尺寸变化率-0.8%～+0.5%；游离和水解甲醛≤40mg/kg ；经纬向水洗尺寸变化率为-1.0%～+0.5%。
涤棉衬布的坯布规格为下列二种中的一种：第一种门幅为 48.5 英寸、纱支数为21s×21s、密度为 60×58根/英寸，第二种门幅为 48.5 英寸、纱支数为16 s×16s、密度为50×45根/英寸。
一种涤棉双面胶粘合衬的生产方法，依次包括翻缝 →前处理→热定形→化学防缩硬挺整理→正面粉点涂层或涂覆涂层→反面涂覆涂层→机械预缩整理。其特征是：热定形时，通过平幅进布，超喂-0.5%～0％上针板，八格热风定形，其中第一、二格温度 180℃，第三、四格温度 190℃，第五～八格温度200℃，两个锡林冷却落布步骤 , 车速为30～35m/min。
化学防缩硬挺整理时，防缩硬挺整理液的组成为：
织物用树脂整理剂 KH-1 60～80 g/L
助剂 STN 150～200 g/L
MgCl2·6H2O 9～12 g/L
乙烯脲 4.0g/L
非离子柔软剂V-12 0.5g/L
其余为水，并用柠檬酸调pH 至3.8～4.2。
涂覆涂层时，HDPE热熔胶在温度155-160℃熔融罐熔融后，通过喷口把液态热熔胶涂覆在布面上，涂覆量70～90 g/L。
本发明涤棉双面胶粘合衬，能把两块面料粘合在一起，以获得较硬手感、较高剥离强力和其他性能，粘合衬干热尺寸收缩率低，粘合衬经纬向缩水率低，游离和水解甲醛小，对生态环境友好，生产工艺操作容易。在涤棉基布的正反两面都有粘合层，可以把同种或不同种的两块面料粘合在一起，以获得较硬手感、较高剥离强力和其他性能，经纬向干热尺寸变化率-0.8%～+0.5%；游离和水解甲醛≤40mg/kg ；经纬向水洗尺寸变化率为-1.0%～+0.5%。
