摘要
在用变性淀粉进行白湿皮试验过程中，优选出用双醛淀粉制作白湿皮的最佳工艺条件：液比１．０，温度２５℃，ｐＨ值８．０，双醛淀粉３％，鞣制时间３小时。该工艺制成的白湿皮丰满，增厚明显，Ｔｓ７８０℃，少铬鞣制时吸铬良好，废液含铬量少，比传统铬鞣法节约红矾５０％左右。成草质量指标除含铬量稍低外，均达到部颁指标。
Through a series of experiments with converted starch,a optimum treatment with dialdehyde is sought out:the float is 100%,water temperature 25℃,pH 8. 0 and the amount of dialdehyde 3%. The treating time is 3 hours' The resulted wet-white leather is full and has an obvious increase in thickness,and its Ts gets to 78℃ And if less chrome tannage is applied,the chrome content of waste water is low,and the consumption of bichromate can be reduced by 50% or so. All but the chrome content reach the standardirations of leather products
