摘要
Abstract
Lignin extract was prepared by degradation of lignin with hydrogen. The content of phenolic hydroxyl of lignin extract was determined by Folin-Ciocalteu reagent method and the chemical structure was analyzed by means of UV and FT-IR. Lignin extract was used in chrome-tanned pigskin grain leather retanning test, the effects of different amount of lignin extract on leather appearances and physical properties were studied. The results showed that the content of phenolic hydroxyl of lignin extract was increased by 30. 12%. The retanning effect was best when the amount of lignin extract was 2%, the leather was elastic, soft and full, the grain face was tight, the shrink temperature was 94. 8 ℃, the tensile strength was 14.5 N/mm2 and the tear strength was 19. 3 N/mm. The retanning performances of lignin extract are as well as vegetable retannage.关键词
