棉针织物低温酶精炼漂白一浴两步法工艺
One-bath two-steps bio-scouring and bleaching of cotton knits
摘要
Abstract
In order to obtain high quality cotton knitted fabric and realize low-temperature scouring and bleaching cleaner production, one-bath bio-scouring and bleaching of cotton knitted fabric at low temperature was discussed. First-ly, the scouring enzyme JLA was screened out which had high activity. Bleaching catalyst S-LTB was added to achieve low temperature bleaching. Secondly, the process was optimized: scouring enzyme JLA 0.4 g/L, surfactant 1305 1.0 g/L, liquor ratio of 1∶10, treating at 55 ℃ for 30 min for bio-scouring; 30% H2O210 g/L, bleaching catalyst S-LTB 1.0 g/L, 50% NaOH 1.0 g/L, treating at 70 ℃ for 30 min for bleaching. The whiteness of the treated fabric at this low temperature process is 70.5%, the strength retention rate is 97.1% and the wetting time is less than 1 s. The effect of low temperature treated fabric is equivalent to that of the traditional high temperature process.关键词
