史氏鲟鱼皮制革工艺研究

On leatherworking technology of Amur sturgeon (Acipenser schrenckii) fishskin

以史氏鲟(Acipenser schrenckii)鱼皮为原料,对其制革工艺进行研究,结果表明,预浸水中添加0.4%的甲醛,防止鲟鱼皮大骨板松动的效果最佳;浸灰液配比为8%石灰、3%硫化钠(含量60%)、1.5%硫氢化钠(含量60%)时,研制的皮革感官评价较佳;软化工艺以酶量0.8%、温度35℃、时间1.5 h研制的皮革感官评价较好;鲟鱼皮的脱色效果以亚氯酸钠(2%)和亚硫酸氢钠(1.5%)组合的氧化还原漂白法效果最佳。研究确立了鲟鱼皮制革优化工艺,该工艺试制的鲟鱼皮革其物理、化学性能指标总体上大大优于QB/T 1873-2004鞋面用皮革标准和QB 1872-1993服装用皮革标准。

The Amur sturgeon cartilaginous taked as the material,the leatherworking technology was studied.Results showed that the optimum formaldehyde addition was 0.4%;8% lime,3% sodimum sulfide（60% content） and 1.5% sodium hydrosulfide（60% content）,the sensory evaluation of leather by this ratio was better;the sensory evaluation of leather in the condition of 0.8 enzyme amount,35 ℃ and 1.5 h was better;and the combination of 2% sodium chlorite and 1.5% sodium bisulfite showed the best bleaching effect.Based on above research,the optimizing leather technology of amur sturgeon fishskin was established.The physical and chemical properties of amur sturgeon leather by this technology were better than the standard of shoe upper leather QB/T 1873-2004 and the standard of clothes leather QB 1872-1993.
