摘要:
The pineapple fibers/four-channel polyester fibers/soybean fibers knitted fabrics was scoured and bleached by the enzyme oxygen one bath process. The effects of the dosage of scourzyme and hydrogen peroxide, pH, temperature on the whiteness, capillary effect and breaking strength of the treated fabrics were analyzed. Through orthogonal test, the scouring and bleaching process was optimized.

摘要:
棉针织物的传统前处理一般采用高温(约98°C)练漂工艺.处理过程能耗大、排污重,织物失重大、手感粗糙.低温精练剂DM-1377、双氧水活化剂DM-1430、漂特灵DM-1436、双氧水活化剂DM-1435可以在前处理中实现棉针织物60°C低温练漂,与传统前处理相比较,低温前处理后棉针织物的白度略低,但顶破强力、手感、失重、棉蜡保留量均有不同程度的提高.用活性BF-3B红1%(omf)对处理后的棉针织物进行染色,并与传统工艺进行K/S值、色差比较,低温精练剂DM-1377处理后的织物染色性能与传统工艺相近,色差控制在合格范围内,同时具备手感好、强力保留率高、棉蜡保留率高等优点.%In the traditional pretreatment of cotton knitted fabrics, exceedingly high temperatures (about 98 °C) are usually used in the scouring and bleaching process. Such harsh conditions will lead to high energy consumption, serious pollution, high fabric mass low, tough hand feeling. The low-temperature scouring agent DM-1377, hydrogen peroxide bleaching activator DM-1430, DM-1436, DM-1435 could be used in low-tem? perature scouring and bleaching of cotton knitted fabric at 60 °C. Compared with the traditional process, the whiteness of fabric treated under low-temperature slightly decreased, while the bursting strength, hand feel? ing, weight loss, wax reservation all had different degrees of improvement. The treated fabrics were dyed by active dye BF-3B 1%(omf), and the K/S value and color difference of which were compared with those of the traditional process. It was found that the fabrics treated by DM-1377 had the similar dyeing performance with the traditional process, the color difference was controlled in an acceptable range. And it had good hand feel?ing, high strength retention rate and high wax retention rate.

Compared with the conventional bleaching process, NOBS and commercial low temperature bleaching, LTB had certain activation on H2O2, and it could promote effective decomposition of H2O2, with high efficiency energy-saving effect. When H2O2/LTB constructed activation system applied to low temperature bleaching of cotton fabrics, cotton fabric whiteness was 75.1, capil ary effect was 8.5 cm/30 min and the fabric breaking strength was 96.8 N/cm, which could meet the requirements of subsequent dyeing and finishing process.

摘要:
涤纶纤维碱性染色是采用耐碱性分散染料及配合专用染色助剂进行染色的一种新型染色方法,是染色工艺发展的新趋势。以往分散染料染色时产生的低聚物大量附着在纤维表面,使纤维变得粗糙,摩擦系数增大,从而影响纤维性能及外观质量,也会影响以后的加工过程,因此很难获高品质的产品。另外,在酸性条件下染色时,所产生的大量油状低聚物也牢固地附着在高温高压机内壁及管道中,这样就增加了缸体清洁的难度。近年来,虽然各种清缸剂不断被开发利用,但其对低聚物的清洗并不理想,而碱性染色能够克服酸性染色的这一弊病,能有效地解决这个难题,使纤维染色后的性能及外观质量大大提高。此外,T/C混纺织物在酸性条件下进行涤纶染色,酸对棉长时间的作用,强力也会损伤、手感明显下降。本文介绍了T/C混纺织物练漂、碱性染色一浴一步工艺,对产品的特点、大货生产进行简述,并对成本进行比较,提出染料适用性选择。采用新工艺、新助剂提高产品质量降低成本提高效益是摆脱困境的有力措施,因此,相信漂底、染涤一浴法碱性染色技术将会有广阔的市场前景及良好的社会效益。
