羊毛纤维水溶出物对重铬酸钾性能的影响

以羊毛在加热处理过程中脱落下来的溶解物为研究对象，测试羊毛溶解物的特性，探讨羊毛溶解物对水溶液中重铬酸钾的影响以及对重铬酸钾吸附羊毛性能的影响。结果表明，羊毛纤维受热后，脱落下来的溶解物主要为可溶性蛋白。可溶性蛋白能使重铬酸钾溶液中电离出的Cr2O7-2转化成Cr+3，由于 Cr+3对羊毛亲和力小，不容易吸附在羊毛纤维上，从而使酸性媒介染料染色残液中总铬含量增多，且主要以三价铬形态存在。本课题为探究酸性媒介染料染色过程中铬污染严重的原因，以及媒染时有效利用媒染剂，减少铬污染提供理论依据。

Effect of solute from wool on properties of potassium dichromate

The solute of the wool in heating process was researched. Then, the property of the solute was discussed and the influence of the solute to the property of potassium dichromate in the aqueous solution and to the adsorption between potassium dichromate and the wool fabric were researched. The results showed that the solute was soluble protein. With the existing of the soluble protein, the CrⅥ in the potassium dichromate was transformed into CrⅢ and because of the little substantively of the CrⅢ to wool, the chrome content was increased in the residual liquid of the dying process with acid mordant dye. So the research was significant to study the reason of chromium pollution in the dying process with acid media dye.
