    • A composition for increasing the resistance to removal by an aqueous liquid of surfactants from a polymeric fabric including fibers having a plurality of fiber-fiber interstices at junctions of two or more fibers. The composition includes water, a first surfactant, and a second surfactant which is structurally dissimilar to and less soluble in water than the first surfactant. One of the first and second surfactants has a solubility in water at 20.degree. C. no greater than about 5 percent by weight, based on the weight of the water. In certain embodiments, the first and second surfactants are adapted to preferentially locate in the fiber-fiber interstices and resist removal therefrom by aqueous liquid. The preferential location of the surfactants in the fiber-fiber interstices of the fabric is accomplished by working the fabric after application of the composition to the fabric. The resulting fabric is wettable and demonstrates increased resistance to removal of surfactants by an aqueous liquid, compared to similar fabrics which have not been worked. The wettable fabrics are especially suited for incorporation in such disposable absorbent articles as diapers, feminine care products, such as sanitary napkins and tampons, incontinent care products, training pants, wipes, and the like.
    • 一种用于增加表面活性剂的水性液体从包含在两根或多根纤维的交界处具有多个纤维间隙的纤维的聚合物织物除去的抗性的组合物。 组合物包含与第一表面活性剂在结构上不相似且较少溶于水的第一表面活性剂和第二表面活性剂。 基于水的重量,第一和第二表面活性剂之一在20℃下在水中的溶解度不大于约5重量%。 在某些实施方案中,第一表面活性剂和第二表面活性剂适于优先定位在纤维 - 纤维间隙中,并通过水性液体抵抗其去除。 表面活性剂在织物的纤维间隙中的优先位置通过在将组合物施加到织物上之后加工织物来实现。 与未加工的类似织物相比,所得到的织物是可润湿的并且表现出对水性液体除去表面活性剂的增强的抗性。 可湿性织物特别适用于诸如尿布,女性护理产品如卫生巾和棉塞,失禁护理产品,训练裤,擦拭巾等一次性吸收制品。
