深色纤维素纤维数码印花织物起白毛现象研究
|
摘要
文中通过对深色纤维素纤维织物活性染料数码印花工艺的研究,详细分析了深色数码印花产品洗涤后起白毛的影响因素,包括纤维性质、生产工艺条件、洗涤次数等。结果表明,纤维素纤维织物活性染料数码印花使用美国Pima棉较佳;在1 000℃,机速80～100 m/min的条件下对织物进行烧毛处理;用150 g/L NaOH,温度45～50℃,机速23 m/min对织物进行丝光处理;墨水量为C级墨喷印4 pass以上;温度102℃,压力25 kPa,蒸化13 min,可以有效降低活性染料数码印花洗涤后起白毛的程度,提高产品的服用耐久性能,以满足消费者的需求。
In this paper, the factors affecting the whitening of dark digital printing products after washing were analyzed in detail through the study of reactive dye digital printing technology for cellulose fiber fabrics, including fiber properties, pretreatment process, producing process and washing process and so on. The results show that American Pima cotton is better for digital printing of cellulose fabrics with reactive dyes; the optimal singeing process is 1 000 ℃ with a speed of 80 ～100 m/min. The inkjet printing pretreatment optimized slurry formulation is 150 g/L NaOH, mercerizing for 45～50 ℃ at 23 m/min; the ink content of grade C needs ink jet printing more than 4 pass; steaming for 102 ℃ at 80～100 m/min, under the pressure of 25 kPa evaporation for 13 minutes. The fastness of the fabrics can effectively reduce the degree of white hair after washing of digital printed fabric with reactive dyes, improve the durability of the products and meet the needs of consumers.
