树脂复鞣剂在猪正面服装革复鞣上的应用

THE UTILIZATION OF RESIN RETANNING AGENT IN RETANNING PROCESS OF PIGSKIN GARMENT LEATHER

对是否用树脂复鞣剂及树脂复鞣剂加入方式作了对比试验,经过观感性能评议和用扫描电镜观察,认为用树脂复鞣剂复鞣猪皮服装革是必要的。多种树脂复鞣剂用量为1%较为合适。中和前后加入树脂复鞣剂对它在革中分布有很大的影响。中和前加入树脂复鞣剂,由于革的 pH 值低,树脂复鞣剂容易在表面聚沉,提高了粒面的紧实性。中和后加入,有利于树脂复鞣剂向革内层渗透,使革身柔软性不变,粒面柔和,对染色影响较小。一次加入树脂复鞣剂对粒面填充增厚作用比二次加入强。上述试验结果为制定猪皮正面服装革复鞣工艺提供了依据。

Contrast experiments were carried out by employing or not employing resin retanning agent and other methods.The identification of the apparance characters and obervation with scanning electron microscope have shown that retanning with resin tanning agent is necessary.Quantity of resin retanning agent is 1%,that was taken to be suitable.
