天然龙井茶色素的制备及应用研究
Preparation and application of natural tea pigments
摘要
Abstract
The optimum extraction conditions of Longjing green tea pigment were obtained by orthogonal experiment: the liquid ratio 1∶50, extraction time 30 min, and the effect of liquid ratio on the yield was greater than the extraction time. The stability of acid base, storage stability and heat stability of Longjing green tea pig⁃ment were determined. The rubbing fastness, washing fastness, light fastness and color difference of dyed cotton fabric with different dyeing process were measured. The differences of Longjing green tea pigment dyed fabrics with different processes were discussed. Longjing green tea pigment was more suitable for mor⁃dant dyeing, especial y for after- chrome- dyeing. Rubbing fastness and soaping fastness were both very high, which could reach the clothing requirement.关键词
