Experimental study on fabric water repellency using nanotechnology

This paper describes the application of nanotechnology to both woven and knitted cotton fabrics by screen printing and padding. Statistical modeling was used to optimize fabric water repellency. The statistical results of screen printing showed that the concentration of silicone-based nanosolution and white spirit were the dominant factors in processing printed woven and knitted fabric. In addition, optimal water repellency effects were achieved on both the woven and knitted fabric using either printing or padding methods. Padding was found to be more appropriate than screen printing because fewer chemicals were used and the production cost was lowered.
