Abstract
Friction coefficient and electrification of textiles are the main factors that specify the quality of cloths. The friction of textiles can be broadly evaluated by the touch of human skin to feel the slipperiness and smoothness. Voltage generated from electrification of the human body by sliding of the head scarf textiles against skin and hair should not exceed certain limit to avoid serious health problems. In the present work, electric static charge generated from the friction of hair and skin against head scarf of different textiles materials as well as friction coefficient have been measured. The experimental results showed that, crape displayed the highest value of friction coefficient when sliding against skin followed by flax, chiffon, cotton, polyacrylonitrile, satin and polyester. The tested types of hair showed different friction behaviour, where African hair showed the lowest friction when slid against crape, chiffon, polyacrylonitrile and flax. Caucasian hair displayed the lowest friction with cotton, jil, and satin. Asian hair gave higher friction with polyacrylonitrile, flax, jil, polyester and satin. The safe level of charge was gained by skin and hair when slid against cotton, jil and chiffon, while the highest voltage values were recorded for polyester, polyacrylonitrile, flax and crape. Skin and hair gained much higher charge than scarf textiles. Caucasian hair gained the highest voltage up to 9500 volts when slid against polyester followed by satin, crape, flax, polyacrylonitrile. It is known that, the relatively high friction as well as high voltage may cause injuries and blisters of skin. Proper selection of textiles that can minimize the generation of electric static charge is desired. Cotton textiles can minimize the generated voltage and provide acceptable values of friction coefficient.
