化纤织物拒油测试评定及分析

Evaluation and Analysis of Chemical Fiber Fabric Oil-repellent Test

化纤织物拒油测试评定标准GB/T 19977—2014《纺织品拒油性抗碳氢化合物试验》中B类液滴范围过于广泛,难以断定织物最终拒油等级。文中采用滴定法,探讨几种试剂对10种化纤织物的拒油效果,观察液滴在织物上的状态,将B类液滴分成B1、B2、B3、B4级并与GB/T 19977—2014对比分析。指出B1、B2类液滴可以评定为A类;B3类液滴可以评定为B类;B4类液滴可以评定为C类。

The range of Class B droplet in chemical fiber fabric oil-repellent testing evaluation of GB/T19977—2014 ＂Textiles-Oil repellency-Hydrocarbon resistance testing＂ is too wide.It is difficult to determine the ultimate oil-repellent grade of chemical fiber fabrics. This paperdiscussed the oil repellent effect of several kinds of reagents for the ten kinds of chemical fiber fabrics with titration method,observed the state of the droplets on the fabric and classified the B droplets into B1, B2, B3, B4 grades and compared them with GB/T 19977—2014. It indicates that the droplets of B1 and B2 can be evaluated as class A; B3 droplet can be evaluated as class B; B4 droplet can be evaluated as class C.
