竹棉/Coolmax交织小提花织物染整工艺

竹棉/Coolmax交织小提花织物染整加工主要包括烧毛、冷轧堆前处理、定形、半丝光、染色和后整理工序。前处理采用低碱冷轧堆工艺和直辊半丝光工艺,烧碱用量160~170 g/L,浸碱时间40~45 s;定形工艺条件为180℃×30 s,以稳定纬向尺寸;染色采用分散/活性浸染工艺,分散染料染色温度宜控制在120℃;拉幅选用亲水柔软整理剂或吸湿排汗整理剂以及两次预缩整理。其成品指标达到英威达Coolmax日常型非弹性机织物的性能要求。

Wet processing of bamboo/cotton/Coolmax mini-jacquard fabric

The dyeing and finishing process of bamboo viscose/cotton/Coolmax interwoven dobby includes singeing, cold pad-batch pretreatment, setting, semi-mercerizing, dyeing and finishing. Optimum process conditions were determined as fol-lows: cold pad-batch pretreatment with low alkali, clipless semi-mercerizing with 160～170 g/L sodium hydroxide for 40～45 seconds; heat setting at 180 ℃ for 30 seconds so as to obtain stable weft dimension; exhaust dyeing with disperse and reac-tive dyes, disperse dyeing at the temperature of 120 ℃, addition of high-temperature leveling agent to improve levelness and softening agent to reduce the friction; finishing with the selected hydrophilic softening agent or moisture-management hygro-scopic agents to attain soft handle and favorable moisture absorbent property; twice pre-shrinking operations. Results showed that the index of finished goods reached the requirements of INVISTA Coolmax everyday non-elastic woven fabric.
