Title: The extraction of green walnut husk dyestuff and its application to cotton knitted fabrics
Abstract: The natural green walnut husk pigment was extracted with water.The concentration,time,pH value,temperature and if it is soaked in before extraction were analyzed respectively.The optimal extraction process were obtained as follows: temperature is 60℃,pH value is 10 ~ 11,time is 90 min,the concentration is 7.2g /100mL,and not be soaked.Through the orthogonal experiments,the optimal dye process with mordant was as follows: mordant is 8%,pH value is 7 ~ 8,additive is A.It can be found from the experiments that adding mordant before dyeing is better than simultaneous and after.
