【摘要】：针对牦牛皮板厚实,裘皮加工时化料难以渗透导致皮板僵硬的问题,本文提出了将酸膨胀分散皮纤维和酸膨胀片皮应用于牦牛裘革制造的新方法。首先研究了六种酸膨胀方案对牦牛生皮膨胀和退膨胀的作用规律,优选出了NaCl-甲酸-硫酸的膨胀方案。并且考察了温度和时间对酸膨胀的影响。最后,对成革机械性能、柔软度和收缩温度等进行了测试。结果表明:在少量NaCl存在的条件下,通过用甲酸和硫酸对牦牛生皮进行适度膨胀,能够很好地去除纤维间质,利于片皮操作。从而促进皮化材料渗透,增加皮板柔软度,并且成革的物理机械性能不会明显受损。
[Abstract]:In view of the thick and solid yak leather plate, it is difficult to infiltrate the chemical material in the processing of fur and lead to the rigidity of the skin plate. In this paper, a new method for the manufacture of yak fur with acid-expanded disperse skin fiber and acid-expandable skin was proposed. Firstly, the effect of six kinds of acid expansion schemes on the expansion and deswelling of yak raw skin was studied. The expansion scheme of NaCl-formic acid-sulfuric acid was selected, and the effects of temperature and time on acid expansion were investigated. Finally, the mechanical properties of leather were studied. The softness and shrinkage temperature of yak skin were tested. The results showed that in the presence of a small amount of NaCl, the fiber stroma could be removed well by moderate expansion of yak skin with formic acid and sulfuric acid. It is beneficial to the skin operation, which can promote the penetration of leather material, increase the softness of leather plate, and the physical and mechanical properties of leather will not be obviously damaged.

【正文快照】： 前言由于牦牛皮具有毛长、毛被稠密、皮板张幅大且强度高的特点,近年来由牦牛皮生产的装饰裘革受到越来越多消费者的喜爱。然而由于牦牛皮部位差大,特别是厚度、胶原纤维粗细及其编织紧密程度差别大,给牦牛装饰裘革的生产带来了很大困难。因此,如何制得皮板柔软有弹性,厚度均
