The effect of corona discharge on fabric thickness in different velocities and rotations
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 4
Abstract
Corona discharge is a kind of gas evacuation activates ionization surrounding the active electrons. Practically, at low-flow about afew if the potential difference increased between two points and the surface, then the electrical discharge will occur from point to surface; this electrical discharge reacts with the surface under radiation and changes the surface properties of the product. In this study, the relationship between number of rotation and linear velocity of corona roller on thickness of cotton fabric would be evaluated. Electrical discharge has happened under 10kv voltage; the distance of top electrode which electrons discharge occurs from there to fabric surface is 3mm from the surface of Corona roller and Corona roller moves on 4 different linear velocities (3,5,6,7)m/min and Corona operation was applied for each velocities in 5 five passages with total rotations (20,30,40.50,70).Some characteristics such as number of rotation and Corona roller velocity have been evaluated by using Analysis of Variance method (ANOVA),Tukey’s multi range Test and determination of correlation coefficients between variables. This study has been used the weft knitting cotton fabric with plain texture and weight of 153 g/mm, and to determine the physical and mechanical characteristics we used thickness gauge machine made by NasjSanj Iran Company and to statistical evaluation we used SPSS software version 13.Based on statistical data obtained from ANOVA method Tukey’smulti range Test, the thickness of cotton fabric was increased in comparison with reference sample or untreated sample in rotation 30 and with velocity of 3m/min maximum of increasing on thickeness has been occurred.
