PET纺粘非织造布氩气等离子体处理的时效性
|
摘要
PET纺粘非织造织物结构中缺少亲水基团,因此几乎无亲水性。采用氩气等离子体处理技术在PET非织造织物的表面引入亲水基团,在不破坏本体结构的情况下,改变其亲水性。通过改变等离子体处理的工艺参数(时间和电压),研究其对PET纺粘非织造织物表面亲水性能、芯吸性能的影响,并对等离子体处理后PET材料的时效性进行探讨。研究表明,等离子处理能使PET纺粘非织造织物的亲水性能提高,拉伸断裂强力基本不变。在处理后的一个月内,等离子体处理效果略有衰减。
PET spunbond nonwoven material surface is not hydrophilic due to the lack of hydrophilic groups. The hydrophilic groups are introduced onto the surface of PET nonwoven by argon plasma surface treatment. The technology changes its hydrophilicity without destroying the main structure. The impact of plasma treatment time and voltage on surface hydrophilic properties and the wicking properties of PET spunbond nonwoven is studied. Then the aging effect of the materials which has been processed by plasma is researched. Studies have shown that plasma treatment technology can significantly improve the hydrophilic properties without negative effect on the tensile strength of the materials.Within a month after the treatment, the result of plasma treatment is slightly reduced.
