Description
技术领域
本发明涉及服装革技术领域,具体涉及一种环保四面弹耳机套革及其制备方法。
背景技术
耳套是指表面为皮革材料的一类耳套,有多种不同材料及工艺。用于缓解耳机佩戴时对人体头部的压迫感。现有技术中由于底布是四向弹力的,故在生产过程中增加难度。现有技术的耳套分为真皮耳套、仿真皮耳套及普通耳套。现有技术中由于底布是四向弹力的,故在生产过程中增加难度。
但是,往往具有以下缺点:1、现有的基布四向弹力的,生产操作难度大;2、现有的普通耳套生产工艺为:溶剂型干法涂层(面层)+湿法溶剂型涂层工艺结合完成,含有有害溶剂,不满足绿色环保的需求;3、手感不佳。
综上所述,为解决现有技术上的不足,本发明设计了一种环保、手感柔软的环保四面弹耳机套革及其制备方法。
发明内容
本发明要解决的技术问题是:本发明设计了一种环保、手感柔软的环保四面弹耳机套革及其制备方法。
为了达到上述目的,本发明采用了以下技术方案:

作为本方案的进一步改进,黏度为5000~20000cps/25℃,涂布量为100~250g/m。
一种环保四面弹耳机套革的制备方法,包括下述步骤:
S1底布复合:复合机将热熔胶复合
S2干法生产线:
1)离型纸放卷→涂覆面层,即涂覆水性表皮层,涂覆刀位0.03-0.15mm→烘干冷却,所用的烘箱温度为60℃~150℃;
2)涂水性中间层,水性浆料,涂覆刀位0.1~0.5mm,烘干冷却,所用的烘箱温度为60℃~150℃;
3)涂覆水性接着层,涂覆刀位0.1~0.3mm,预烘干,所用的烘箱温度为60℃~120℃,在烘箱内停留时间为50s~120s,再贴合复合底布后进行烘干,所用的烘箱温度为60℃~150℃,成品分离;
4)背面布分离
5)揉纹,通过连续揉纹机对成品进行加水揉纹、干燥定型。
作为本方案的进一步改进,复合底布层为四面弹高弹力尼龙针织布,通过热熔胶粘合剂复合机织布。
本发明提供的环保四面弹耳机套革及其制备方法与现有产品相比,具备下述有益效果:
1)水性涂层的设计,使用以水作为溶剂的PU树脂进行表面、中间层、接着层工艺配方设计,避免了有害溶剂使用,更具体的:水性面层涂层配方设计:高固含、表面亲肤性,可高频粘连;其中,水性中间层的优化选择,通过选择高固含(30%~60%)、可通过稳泡剂、发泡剂用量的调节,及结合水性自动发泡设备的运用,根据需求调节发泡倍率,满足手感、物性要求;水性接着层树脂通过发泡工艺设计,减小了树脂与底材的接触面积,较不发泡涂层设计有明显的柔软手感提升;
2)双发泡涂层设计,可以更精确的控制泡孔大小,调节每一层的发泡倍率,达到产品的设计需求;
3)中间发泡层水性树脂通过调节50~200%倍的发泡倍率,达到柔软的手感;
4)水性发泡涂层贴合,既满足与底布的贴合性,又通过降低涂层密度,精确控制底浆上浆量,减少渗浆对手感的影响,使成品手感丰满、柔软;
5)产品最后通过轧水揉纹的工序,使成品最终手感更加柔软、丰满。
6)DMF无残留,环保,水性涂层是以水为溶剂的PU浆料,使用过程中不添加任何有害溶剂,绿色环保。
