بررسي تاثير دما بر خصوصيات اسطكاكي بافت هاي حلقوي پودي ساده پنبه اي در محيط هاي نسبتا خشك

The purpose of this research is the investigation of the variations of temperature on softness and frictional behavior of plain knitted cotton fabrics. Because of these fabrics directly contact to body skin, therefore it is necessary to determine the temperature influence on the perception of fabrics and pleasantness. To consider this purpose, the cotton plain knitted fabrics as subjected to different temperature (0°c, 25°c and 50°c) and the constant relative humidity (rh=25%). Then the frictional parameters were obtained by using of methods friction (Ajayi 1992). The results showed that temperature rate significantly affect on frictional properties. Intact, increased temperature (in rh=25%) increase the resistance friction plain knitted cotton fabrics. Also other results determine that the most of values between frictional statics and dynamic in dry humidity conditions occurred at 25°c.
