摘　　要：针对传统棉织物冷轧堆白度不稳定、强力损伤大等问题,文中探究了催化剂在纯棉针织物冷轧堆前处理工艺中的应用。通过单因素试验,探究了精练剂、催化剂、分散剂、稳定剂、片碱及双氧水用量对纯棉针织物白度、毛细效应及顶破强力的影响,并对工艺进行了优化。结果表明,室温条件下,优化后的最佳工艺为:片碱用量15g/L、100%双氧水用量20g/L、精练剂CML用量10g/L、催化剂GFF用量5g/L、分散剂PF71用量2g/L、稳定剂KKV-C用量10g/L,处理后织物的白度为72.20,毛效为15.5cm,顶破强力为837 N。与传统冷轧堆工艺相比,该工艺能够改善处理后织物的白度、毛细效应及顶破强力。Due to the problems of unstable whiteness and big strength damage of cotton fabrics in the traditional cold pad-batch,this paper explored the application of catalyst in the cold pad-batch process of cotton knitted fabrics.The effects of refining agent,catalyst,dispersant,stabilizer,soda ash and hydrogen peroxide dosage on the whiteness,capillary effect and bursting strength of cotton knitted fabrics were investigated through single factor experiment,and the process was optimized.The optimized process at room temperature is as follows:sodium hydroxide 15 g/L,hydrogen peroxide(100%)20 g/L,refining agent CML 10 g/L,catalyst GFF 5 g/L,dispersant PF712 g/L and stabilizer KKV-C 10 g/L.The whiteness of the treated fabrics is 72.20,the capillary effect is 15.5 cm,and the bursting strength is 837 N.Adding appropriate amount of catalyst GFF in the treatment solution can improve the bursting strength of the fabric.Compared with the traditional cold pad-batch process,this process can improve the whiteness,capillary effect and bursting strength.
