超声波协同纤维素酶对纯棉色织物超柔整理的影响

为了弥补传统柔软工艺的不足,使织物达到超柔软的效果,利用超声波协同纤维素酶对纯棉色织物进行柔软整理。通过改变纤维素酶处理时的浓度、温度、时间及pH值等因素,测试再经柔软整理后的纯棉色织物的弯曲、吸湿性、折皱回复角及强伸等性能指标,并分析使柔软性改善的原因。实验结果表明:超声波协同纤维素酶对纯棉色织物进行预处理后再经柔软整理,可达到良好的柔软效果,同时纯棉色织物的其他物理机械性能也得到一定程度改善,并且缩短了处理时间,节省了资源。

Effect of synergistic treatment of ultrasonic and cellulase on super-softening finishing of yarn-dyed cotton fabric

To make up the disadvantages of traditional softening technique and obtain the super soft effect of the fabric,yarn-dyed cotton fabric was pretreated by cellulose,followed by ultrasonic treatment.Influences of enzyme concentration,temperature,treating time and pH value on the bending property,moisture absorption,crease recovery angle,strength and elongation of the treated fabric were studied.Preliminary analysis was conducted of the reason why softness was improved.The results showed that when yarn-dyed cotton fabric is pretreated by compound finishing of ultrasonic and cellulose,and then given softening treatment,the treated fabric can be rendered excellent soft effect;meanwhile other physical performances are also improved to certain degree.In this way,both processing time and resource are saved.
