The present invention provides a method for leather dressing of sturgeon skin and sturgeon leather produced by the method. Including the sturgeon leather method: 1) on the skin of sturgeon raw materials were pretreated with bone deck cleaning, soaking and degreasing; 2) the pretreated cleaning, soaking and degreasing of sturgeon Piyi order bone softening, acid leaching deck preliminary softening and tanning process, the bone softening deck; 3) on deck after bone softening, softening and preliminary pickling tanning treatment and bone softening skin of sturgeon and deck retanning, dyeing and fatliquoring, drying, obtained bone softening of sturgeon leather with deck. Made from sturgeon leather by using the method of the invention, soft, breathable, excellent tear resistance, wrinkle resistance, bone deck sturgeon skin unique firmly attached to the surface of leather do not fall off, and the bone deck bending degree 45 ~ 90 degree angle between the bone will not break, deck clear, natural pattern beautiful and stylish.
【技术实现步骤摘要】
本专利技术是关于一种鲟鱼皮制革方法以及按照该方法制作得到的鲟鱼皮革,具体是关于一种对鲟鱼皮进行骨甲板初步软化、鞣制等工艺而制作得到鲟鱼皮革的方法,以及按照该方法制作得到的带有软化的骨甲板的鲟鱼皮革。
技术介绍
鲟鱼(鲟,拉丁文学名Acipenser sturio Linnaeus,英文名Commonsturgeon) 是现存的古老生物种群,鲟鱼体形奇特,头呈犁形,口下位,尾歪形,体背五行大骨甲板(骨板),体形大(0.5 7米不等),寿命长。野生鲟鱼在我国黑龙江、长江、长江至珠江各河流及沿海均有分布。鲟鱼的养殖驯化在我国大部分地区都已展开并已具有一定规模,以长江流域而言,鲟鱼养殖场就有几百家,以第三代鲟鱼为养殖主体。鲟鱼经济价值很高,通常是加工成鲟鱼肉、鱼籽酱等类食品大量出口创汇,在加工过程中被淘汰下来的鲟鱼皮由于鲟鱼皮表面有大量的骨甲板无法食用且带有浓重的鱼腥味而通常是被抛弃,如果能将这些鲟鱼皮加以利用,变费为宝,将具有非常现实的意义。鲟鱼皮抗撕裂性、耐靡性、柔韧性可与鳄鱼皮媲美,且皮面上带有独特的五行骨甲板,在每行骨甲板与骨甲板之间布罗着密密麻麻如星星一样 ...
【技术保护点】
1.一种鲟鱼皮制革方法,该方法包括:1)对带有骨甲板的鲟鱼皮原料进行清洗、浸水、脱脂预处理;2)对经过清洗、浸水、脱脂预处理的鲟鱼皮依序进行骨甲板初步软化、浸酸软化以及鞣制处理工序,使骨甲板软化,其中:所述骨甲板初步软化的具体操作包括:将鲟鱼皮浸入含有鲟鱼皮重量8%~12%的氯化钠的盐水处理液中浸泡30分钟以上;然后在该浸有鲟鱼皮的盐水处理液中加入鲟鱼皮重量1.0%~1.6%的甲酸,使鲟鱼皮继续浸泡30分钟以上;再加入鲟鱼皮重量0.3%~0.7%的蛋白酶,搅拌水解15~25分钟,检测处理液pH值1.5±0.1;该骨甲板初步软化的工序中,控制处理液中水含量不超过鲟鱼皮重量的2 ...
