摘　　要：为了提高棉织物的硬挺度,降低织物上游离和水解甲醛含量,采用醚化六羟树脂M-6与PVA复配对棉织物进行硬挺整理。探讨了M-6树脂用量、PVA用量、催化剂用量、pH值、焙烘温度和焙烘时间对整理织物性能的影响。在单因素试验的基础上,通过正交试验优化得到最佳工艺:醚化六羟树脂M-6用量180g/L,PVA用量25g/L,催化剂氯化镁用量15g/L,整理液pH值5,100℃预烘3min,170℃焙烘2.5min。整理后棉织物的弯曲长度提高了6.44cm,织物上游离和水解甲醛量为138.1mg/kg,撕破强力下降率为23.0%,白度无明显变化。In order to improve the stiffness of cotton fabric and reduce the content of free and hydrolyzed formaldehyde on the fabric,stiffening finishing of cotton woven fabric was carried out with etherified hexahydroxyl resin M-6 and PVA.The influences of dosage of resin finishing agent M-6,PVA and catalyst,pH value,curing temperature and time on the performances of cotton fabric were discussed.On the basis of single factor test,the finishing process was optimized by orthogonal test method.The results showed that the optimum finishing process was the amount of M-6 resin of 180 g/L,PVA of 25 g/L,MgCl_2·6 H_2O of 15 g/L,pH value of 5,pre-drying at 100℃for 3 min,curing at 170℃for 2.5 min.The bending length of finished fabric increased by 6.44 cm,the content of free and hydrolyzed formaldehyde was 138.1 mg/kg,the tearing strength decreased by 23.0%,and the whiteness changed a little.
