北方猪正软鞋面革加工过程中几个主要工序在制品的组织学研究

HISTOLOGICAL STUDY OF SEMIPRODUCT IN SOME MAIN PROCESSES OF SOFT UPPER LEATHER MADE FROM NORTH—CHINA PIGSKIN

采用光学显微镜和扫描电镜对北方猪正软鞋面革加工过程中大小液比浸灰碱、多工序加油、多种复鞣剂结合复鞣在制品进行了组织学研究。结果表明,小液比浸灰碱、多工序加油、多种复鞣剂结合复鞣是制造猪正软鞋面革的主要技术关键。

Histological structure of semiproduct in liming with long or short ra- tion,fatliqualing in many processes,combination retanning have observed with optical microscope and scanning electron microscope resprctively.The results have shown that the technical keys to making soft upper leather from North—China pigskin are liming with short rationm,fatliqualing in many processes,combination retanning with many types retanning agent.
