Abstract
减少复漂的前处理工艺，涉及纺织技术领域，主要由烧毛、浸渍、冷堆、煮练、煮练堆置、水洗、漂白、再堆置和再水洗工艺步骤组成。特点是：在浸渍液后、煮练前将面料置于进行10～30℃的环境温度下冷堆。本发明在原工艺基础上引进了冷堆工艺步骤，可减少一道长车氧漂，能耗降低，同时减少了污水排放的量。本发明适合对全棉、涤棉、棉包氨纶、棉锦等面料的处理，用此工艺生产的面料，质量达到原工艺复漂后的效果。
Description
技术领域
本发明涉及纺织技术领域，特别是织物的后处理工艺技术。
背景技术
漂白布白度要求高，正常的加工流程为烧毛、退煮漂、复漂，此工艺能耗较高。
现行的退煮漂、复漂工艺存在的缺陷：
1、用退煮漂、复漂工艺生产时降强相对较大，产生氧化洞的风险增大，产生的疵布率相对较高点。
2、用退煮漂、复漂工艺生产时消耗较高，尤其是水电汽消耗和污水的排放量相对较多。
3、用退煮漂、复漂工艺生产时机台的产能受到影响，使整体产能降低近一半，从而影响效益。
发明内容
本发明目的在于提出一种能克服以上现有技术缺陷的前处理工艺，以减少复漂工艺。
本发明主要由烧毛、浸渍、冷堆、煮练、煮练堆置、水洗、漂白、再堆置和再水洗工艺步骤组成。特点是：在浸渍液后、煮练前将面料置于进行10～30℃的环境温度下冷堆。
本发明的工艺特点：在原工艺基础上引进了冷堆工艺步骤，可减少一道长车氧漂，能耗降低，同时减少了污水排放的量。本发明适合对全棉、涤棉、棉包氨纶、棉锦等面料的处理，用此工艺生产的面料，质量达到原工艺复漂后的效果。
本工艺的优点：
1、节约生产成本，提高了煮漂机的产能和效率，为保证产能减少了设备的投入。
2、避免了复漂导致的污水的排放。
另外，本发明所述冷堆的堆置时间为24±1小时。由于在10～30℃的环境温度下冷堆，温度低，必须要有充分的作用时间，让工作液能与面料内的杂质充分反应，以保证后续加工能达到要求（如白度、毛效等）。
具体实施方式
现以50S全棉面料为例，具体生产工艺步骤有：烧毛、浸渍、冷堆、煮练、煮练堆置、水洗、漂白、再堆置和再水洗。
1、烧毛：
车速 110m/min；
风压 13bar；
火口只数 2 ，正反面烧毛，烧毛等级 3-4级。
2、浸渍：
车速为：60±5m/min。
采用的浸渍液配方为：NaOH:190g/L(滴定值50-55g/L)、H2O2：77g/L(滴定值20-22g/L)、HOP稳定剂：12g/L、CPB-2精炼剂：20g/L、HAS裂解剂：2g/L，其余为水。
3、冷堆：
冷堆时的环境温度为10～30℃，堆置时间：24±1小时，根据温度来确定时间。
4、煮练：
车速为：60m/min；
第1至4级水洗温度为90～95℃；
在浸轧槽内置入煮练用液，配方：
NaOH:116 (滴定值40-45ml/kg)；KE:5 g/L；HD-X:5 g/L；其余为水。
煮练用液的温度为：50±2℃。
5、煮练堆置：
堆置蒸箱温度为101～103℃；
堆置时间：60～65min。
6、水洗：
第5至10级水洗温度为90～95℃。
7、漂白：
车速：60 m/min；
第11级水洗温度为30～40℃。
漂白液配方为：净棉素：设定值20kg，NaOH滴定值3-3.5g/l；H2O2：18.4(滴定值5～5.5g/L)；HD-X:3g/ L；其余为水。
漂白液工作温度为：30～40℃。
8、再堆置：
堆置环境温度：97～100℃
堆置时间：30min
9、再水洗：
下道工序为丝光的品种第12至16级水洗温度为90～95℃；如下道工序为定型的品种第12至14级水洗温度为90～95℃，第15水洗温度为60℃，调酸pH值为4.5～5 ，第16水洗温度为60℃。
对涤棉、棉包氨纶、棉锦等面料采用以上工艺进行前处理，同样也能达到原工艺复漂后的效果，同时减少一道长车氧漂，能耗降低，同时减少了污水排放的量。
