摘要

For outdoor sports, waterproof breathable materials are widely used to provide protection from environmental factors like rain and wind. The most important techniques to achieve excellent performance use perfluorinated organic substances, which must be replaced in the near future due to health concerns and their environmental persistency. Printing of textile materials with reactive silicone pastes could be an alternative to introduce water repellency without fluorocarbon finishing. In this work, production of barrier textiles through one-step silicon printing was studied, using a two-component paste with long pot life and a thermal fixation step. Three different knitted fabrics made from micromodal, polyamide/elastin, and cotton/polyester were used as substrates for the printing. The achieved hydrophobic modification of the fabric was analyzed by determination of water shedding angle, water resistance, water retention values, moisture content, air permeability, tensile properties, and infrared spectroscopy. The results indicate several areas of technical application for the modified fabric, such as barrier textiles with permeability control, localized modification of mechanical properties of fabric and garment.
