Influence of plasma treatment on hydrophilicity of raw cotton fabrics

In order to improve the hydrophilicity of raw cotton fabrics,the influence of plasma treatment parameters on the surface properties of raw cotton fabrics was studied,focusing on effects of plasma treatment time,treatment power and treatment distance on the wickability of the raw cotton fabrics.The XPS analysis showed that a remarkable increase of C—O—H、C-O and O—C-O bonds on the surface of the cotton was observed after plasma treatment,and the wettability was greatly improved.The wicking height of the fabric increased with the increase of plasma treatment time.But when treatment time was over 25s,the increase amount of wicking height decreased.The wicking height of the fabric increased with the increase of plasma treatment power.But the wicking height of the fabric decreased as the plasma treatment distance increased.The yarn tensile strength test showed that the tensile strength increased with the increase of plasma treatment time.
