Description

一种皮革生产工艺
技术领域
本发明涉及皮革加工领域，具体涉及一种皮革生产工艺。
背景技术
皮革是经脱毛和鞣制等物理、化学加工所得到的已经变性不易腐烂的动物皮。革是由天然蛋白质纤维在三维空间紧密编织构成的，其表面有一种特殊的粒面层，具有自然的粒纹和光泽，手感舒适，因此被人们所广泛的应用，然而现有技术中皮革的加工工艺较为混乱，加工出的皮革质量较差，用其制成的各种皮革制品耐用度差，不能满足消费者的需求。
发明内容
为了解决上述技术问题，本发明提供一种皮革生产工艺，该生产工艺操作简单，制作出的皮革耐用度强，能够满足消费者的需求。
本发明的目的通过以下技术方案来具体实现：
一种皮革生产工艺，包括以下步骤：
1）组批：将张幅大小、厚度较近的皮的原皮分类，放在同一个鼓中加工；
2）浸水：对组批后的原皮进行浸水，使其恢复到鲜皮的状态，在水中添加有浸水助剂，加速水的浸透；
3）脱毛、脱脂：将皮中细胞内的油脂及原皮表面的毛脱掉，露出天然、细致的粒面；
4）浸灰：加入碱使皮膨胀到一定的厚度，利于剖层；
5）脱灰、浸酸：将浸灰过程中皮中多余的碱除去；加入适当的酸，中和掉多余的碱，使其达到鞣制所需的PH值；
6）鞣制：利用三价铬离子将皮纤维的胶原基团连接起来，增强皮革的抗张、抗撕裂的强度，PH值约为3.8-4.2，温度为35-39℃，时间为9-11h；
7）复鞣：选择填充作用较强的复鞣剂对鞣制后的皮进行复糅，温度37-39℃，PH值为5.0，时间为40 -50分钟；
8）染色：将皮染制成要求的颜色；
9）加脂：加脂时的PH值为5.0，温度60℃，时间1.3h；
10）干燥：采用贴板干燥和烘干方式对皮进行干燥；
11）拉软：采用机械方法对干燥以后的皮进行拉软；
12）涂饰： 对皮进行涂饰，挺高皮的美观性；
13）检验及成品入库。
本发明一种皮革生产工艺，包括以下步骤：组批→浸水→脱毛、脱脂→浸灰→脱灰、浸酸→鞣制→复鞣→染色→加脂→干燥→拉软→涂饰→检验及成品入库，操作简单，制作出的皮革耐用度强，为厂商节约成本，同时能够满足消费者的要求。
具体实施方式
本发明实施例所述的一种皮革生产工艺，其特征在于包括以下步骤：
1）组批：将张幅大小、厚度较近的皮的原皮分类，放在同一个鼓中加工；
2）浸水：对组批后的原皮进行浸水，使其恢复到鲜皮的状态，在水中添加有浸水助剂，加速水的浸透；
3）脱毛、脱脂：将皮中细胞内的油脂及原皮表面的毛脱掉，露出天然、细致的粒面；
4）浸灰：加入碱使皮膨胀到一定的厚度，利于剖层；
5）脱灰、浸酸：将浸灰过程中皮中多余的碱除去；加入适当的酸，中和掉多余的碱，使其达到鞣制所需的PH值；
6）鞣制：利用三价铬离子将皮纤维的胶原基团连接起来，增强皮革的抗张、抗撕裂的强度，PH值约为3.8-4.2，温度为35-39℃，时间为9-11h；
7）复鞣：选择填充作用较强的复鞣剂对鞣制后的皮进行复糅，温度37-39℃，PH值为5.0，时间为40 -50分钟；
8）染色：将皮染制成要求的颜色；
9）加脂：加脂时的PH值为5.0，温度60℃，时间1.3h；
10）干燥：采用贴板干燥和烘干方式对皮进行干燥；
11）拉软：采用机械方法对干燥以后的皮进行拉软；
12）涂饰： 对皮进行涂饰，挺高皮的美观性；
13）检验及成品入库。
本发明一种皮革生产工艺，包括以下步骤：组批→浸水→脱毛、脱脂→浸灰→脱灰、浸酸→鞣制→复鞣→染色→加脂→干燥→拉软→涂饰→检验及成品入库，操作简单，制作出的皮革耐用度强，为厂商节约成本，同时能够满足消费者的要求。
