Studies on the Warp Sizing of Cupra Cloths

The purpose of this study is to investigate the characteristics of cupra yarn 75d sized by various sizing recipes. The results obtained in this experiment are summarized as follows; 1. Sizing recipes suit to 3∼4% of adhesives, 0.2∼0.3% of oil, 0.2∼0.3% of antistatic agent and 3∼4% of add-on of sizing agents. 2. The results are 34∼60 dyne/cm of surface tension and 1.50∼4.00 of relative viscosity for the sized yarn, about 150g of tensile strength, 9.0∼10.0 of friction coefficient, 1∼3 volts of antistatics at 500 cycles, 5∼13 turns of abrasion resist, for the sized yarn, and 1∼10% of add-on of size. and 8∼10% of moisture regain.
