Effect of atmospheric pressure DBD plasma on capiliary of cotton-polyester blend fabric

In this study, the cotton-polyester blend fabric was treated by atmospheric pressure DBD plasma (APDBD plasma). Ten different experimental conditions were performed with the change in plasma power and the fabric movement speed. The central composite designs type face centered (CCF) was used to design experiments. The wicking height of un-treated and treated sample were determined. The Design Expert V 10.0.8 software was used to evaluate the relationships between the two variables (plasma power and movement speed of the fabric) and the wicking height of treated fabrics. Two response models between two variables and the wick height in the warp and weft directions of the treated fabric were found. The fiber surface of un-treated and treated sample was also observed by using SEM. The results show that the APDBD plasma treatment for cotton-polyester blend fabric could improve its wicking height, this improvement may depend on the plasma power and fabric movement speed (exposure time).
