摘要
为研究拒水整理对棉织物洗涤效果的影响,以不同结构的氟碳拒水拒油整理剂和碳氢类拒水整理剂为研究对象,考察了织物表面能、织物表面Zeta电位、织物的沾污性能等因素对洗涤效果的影响。结果表明,拒水整理后织物表面能的变化与污渍的洗净力大小相关,水溶性污渍的洗净力随着织物表面能的降低而提高;油溶性污渍在未整理的纯棉织物上洗净力最高,而在较低表面能的拒水整理织物上的洗净力最低;随着拒水整理后织物与污渍Zeta电位和绝对值的减小,油溶性污渍的洗净力也有降低的趋势;拒水整理后织物沾污性能的变化也会影响织物的洗涤效果。
The effect of water-repellent finishing on the washing result of cotton fabric was studied with different structures of fluorocarbon water-and-oil-repellent finished cotton fabrics and hydrocarbon water-repellent finished cotton fabrics.The influences of surface energy,surface Zeta potential and contamination characteristics of fabric on washing result were studied.Results show that the detergency of stains is relevant to the surface energy of fabric,and the detergency of water-soluble stains increases with the decrease of the surface energy of fabric.The detergency of oil-soluble stains reaches the highest level on unfinished pure cotton fabric,and the lowest level on water-repellent finished fabric with low surface energy.With the decrease of Zeta potential and absolute value of water-repellent finished fabric and stains,the detergency of oil-soluble stains takes on a decreasing trend.The change of the contamination performance of water-repellent finished fabric also will affect the washing result of fabric.
