摘　　要：用棉织物进行数码印花时,由于前处理上浆使得喷到棉织物上的墨水量较少,存在得色率较低、色光不鲜艳的问题。利用自制活性墨水提高棉织物印花固色率的同时,研究了前处理上浆工艺、蒸化工艺及皂洗工艺对印制效果的影响。采用传统海藻酸钠及自制羧甲基淀粉糊料,最佳上浆工艺为:糊料用量4%,上浆率15%~20%,碱剂用量15~30 g/L,尿素用量30~40 g/L,防染盐S用量4 g/L;在饱和蒸汽(102℃)下汽蒸7~10 min时,固色效果显著。此时,数码印花织物的固色率为73.92%~74.20%,耐皂洗色牢度为3~4级,耐干摩擦色牢度为5级,耐湿摩擦色牢度为4~5级。When cotton fabric was digitally printed, the amount of ink sprayed on cotton fabric was less because of the sizing process in pre-treatment. The yield rate of color was low, and bright color was dark.The fixation rat of cotton fabric was improved by using the self-made reactive ink. The effect of sizing process in pre-treatment, steaming and soap washing process on printing effect were studied. Using traditional alginate and self-made carboxymethyl starch paste, the best sizing process was as follows： paste concentration 4%, sizing rate 15%-20%, alkali dosage 15-30 g/L, urea dosage 30-40 g/L, anti dyed salt S dosage 4 g/L.When the steaming time of saturated steam（102 ℃） reaches 7-10 min, the fixation effect was remarkable.Then, fixation rate was 73.92% -74.20%, the color fastness to soaping was 3-4 level, the color fastness to dry rubbing was 5 leve, and the color fastness to wet rubbing was 4-5 leve.
