摘　　要：选用栗木栲胶和余柑栲胶应用于皮革染色,以硫酸铁和硫酸亚铁为媒染剂,探究了媒染剂的用量、加脂剂和中和pH对栲胶媒染性能的影响。结果表明:皮革的干湿擦牢度会随着媒染剂用量的增加而下降,当媒染剂用量为2%时,干湿擦牢度等级均在4以上,符合鞋面革和服装革的要求;皮革经媒染后加脂,颜色会变浅,加脂剂具有一定的败色作用;中和pH对皮革染色性能影响不大,pH值为5.0～6.0时染色效果相对较好。Chestnut extracts and emblic extracts were chosen to be applied in leather dyeing. Ferric sulfate and ferrous sulfate as mordant dye, the amount of the mordant, the fat liquor and the pH that affects the dyeing behavior were investigated. The re- suits show that with the increase of the amount of mordant, the dry/we＇t rubbing fastness of leather decreases, which is above 4 grade, meeting the demand of shoe upper leather and garment leather when the amount of mordant is 2%. The color of leather is lighten after fatliquoring and fatliquor has fad effect. The neutralization has little influence on leather dyeing and when the pH is 5.0 - 6. 0 dyeing effect is better.
