Description

干法生产再生革
本发明涉及一种利用皮革废料进行再生产的再生革的制造方法。
目前传统的再生革制造方法都采用湿法制造工艺，其工艺方法需要使用大量的水，因而会产生大量的污水，按此方法，每生产10吨成品再生革会排出约80吨的污水。同时，这种方法所采用的粘合剂及其它助剂的成本高，烘干硫化加热耗能大，而生产出来的成品品质差，只能用于低档的产品上。
本发明的目的在于克服现有技术的上述缺陷，提供一种无污染、低能耗、高质量的再生革的制造方法。
本发明的工艺方法如下：1、皮纤维剥离制取2、添加辅料并混合3、铺网4、针刺预固5、热熔粘合6、压挤、冷却
本发明的工艺对比传统的湿法工艺具有如下优点：1、湿法生产的全过程离不开水，以连续生产的长网机为例，要生产1吨成品再生革要消耗80吨的水，也就是说每生产1吨再生革就要排出污水80吨，而本发明却无此项污染。2、湿法生产能耗大，因为湿法生产的再生革坯料经过挤压仍含有50％的水分，要把它烘干到含水量为10％的成品时需要大量的能耗，而本发明无此项能耗。3、湿法生产所需的粘合剂——乳胶占总量的50％且还需要其它多种助剂，本发明所需的粘合剂为热固纤维占重量的10～30％且不需其它助剂，所以成本低。4、在湿法生产过程中其皮纤维长度如果过长会使浆料产生絮聚作用，所以其纤维长度一般在3～8mm，由于纤维的长度过短使其成品的内部相互的聚合力差，直接影响了成品的物理性能，而本发明中皮纤维的长度不受此限制，所以各项物理性能均优于湿法生产。5、湿法生产至今在生产技术上无新的突破，没有新的发展，仍然保持用于低档产品，而本发明引入了现代的一些新技术、新工艺，如非织造布中的水刺技术、铺网技术、热粘合技术等转移应用在再生革的生产制造上，使其产品的质量有了明显地提高，可以满足制鞋、制箱及合成革等多种高档行业的要求。
以下结合附图及实施例进一步阐明本发明的详细内容。
附图为本发明的生产工艺简图。
本实施例是制造鞋用中底再生革。将废料皮革根据颜色、厚度等不同进行手工筛选，将经过筛选后的原料送入皮革开松剥离机构1内，该机构内设有外圆布满钢针的滚筒，滚筒高速旋转并通过钢针将送来的皮革撕离成纤维束，经该机构剥离的皮料基本达到开松和剥离，但还有还混有尚未被撕离的小块皮料和粉碎的粉末；将经过开松剥离机构处理的皮料送入风选机构2，该机构通过风力根据各物料的重量不同将纤维束分离出来；分离后的纤维束送入混合机构3，同时混入热固化纤——丙纶短纤维并使其含量达到整体重量的30％，均匀混合；混合后的混合料送入铺网机4，混合料在该机内经过梳理、混合、除杂后铺网形成再生革的纤网层；将该纤网层送入预固针刺机5内进行针刺，使其达到一定的强度；再送入烘箱6，当烘箱中温度达到170℃时，纤网层中的丙纶纤维熔化将皮纤维粘合；当纤网层离开烘箱后由压辊7进行压挤，使疏松的网层压缩致密，同时冷却定型。
