摘要
采用正硅酸乙酯(TEOS)为前躯体,乙醇为溶剂,盐酸为催化剂制备硅溶胶,并加入添加剂对棉织物进行改性;测试整理后织物的拒水性能,以及织物的手感、透气性、断裂强力和染色性能的变化。结果表明,溶胶拒水整理略降低织物的透气性和手感,而断裂强力有所提高;直接染料染色织物拒水整理后,色光略有变化,颜色加深,牢度基本不受影响。
In order to obtain water repellent properties of cotton fabric, the silica sol was prepared with precursor TEOS, solvent ethanol, catalyst hydrochloric acid and then applied to modify cotton fabric with the additives. The water repellent properties, handle, air permeability, broken strength and dyeing behavior of the finished fabric were tested. The results showed that the water repellent finish decreased air permeability and handle properties but good tensile strength was reached. For the fabric dyed with direct dyes after water repellent finishing, the shade was slightly changed, the deeper color was achieved. There is no negative effect on color fastness,
