摘要
研究了碱减量处理中碱液浓度、处理温度、处理时间以及促进剂等工艺条件对防寒涤纶面料减量率的影响。同时,还研究了碱减量处理对面料透气性的影响,以及对其后的拒水拒油整理效果及耐洗涤性的影响。结果表明,随碱液浓度提高、处理温度增加、处理时间延长,面料的减量率和透气性随之提高,面料表面亲水性和表面粗糙度增加,使织物在后整理中可获得更好的拒水拒油性能和耐水洗性;但减量率不宜太高,在4%～6%左右较为合适;另外,使用阳离子表面活性剂作为碱减量处理的促进助剂,可降低碱的用量,达到既提高处理效率又降低成本的目的。
In this paper, the effect of processing parameter, such as alkali concentration, temperature and process time on the alkali deweighting rate and alkali deweighting efieiency of cold-proof garment fabrics was studied. It found that with the increase of alkali concentration, temperature and process time, the alkali deweighting rate and the air permeability of fabrics increased. Meanwhile, it could obtain better effect on the following functional finishing and washing resistance. The best alkali deweighting rate is in the range of 4% to 6%. It also found that the using of cationic surfactant could accelerate the alkali deweighting finishing.
