    摘要： A fibrous polyamide or wool substrate having resistance to staining by acid colorants comprises, a fibrous polyamide or wool substrate having applied thereto a sulfonated aromatic condensation resin, said resin being a condensation product of a sulfonated dihydroxydiphenyl sulfone, a dihydroxydiphenyl sulfone, a sulfonated naphthalene and an aldehyde; or a sulfonated dihydroxydiphenyl sulfone, a sulfonated naphthalene and an aldehyde; optionally a methacrylic acid polymer is also applied thereto as well as a fluorochemical; an aqueous formulation of the resin is also provided which formulation may include the methacrylic acid polymer as well as the fluorochemical Additionally there may be employed a salt to enhance exhaustion of components onto the substrate; a method of treating a fibrous polyamide or wool substrate employing the formulation is also provided.

    摘要： A method of treating articles having a textile surface (such as broadloom carpets or carpet tiles) with a stainblocker composition is disclosed. A pile surface structure having pile elements containing nylon yarns having both acid dyeability and cationic dyeability is dyed with both acid dye and cationic dye and then passed through a hot stainblocker treatment bath and a cooling zone. Substantially the entire height of each pile element is coated with a stainblocker composition whereby the pile surface structure has a stain resistance of 9 or higher on the AATCC Red 40 Stain Scale. The resulting pile surface has good color separation and stability, and no color loss from the catatonically dyeable yarns.

    摘要翻译： 公开了一种用防污剂组合物处理具有织物表面的制品（例如宽幅地毯或地毯）的方法。 具有含有酸性染色性和阳离子染色性的尼龙纱的绒头元件的绒头表面结构用酸性染料和阳离子染料染色，然后通过热污渍阻挡剂处理浴和冷却区。 基本上，每个绒头元件的整个高度都涂上防污剂组合物，由此在AATCC Red 40 Stain Scale上，绒面表面结构的耐污染性为9或更高。 所得的绒头表面具有良好的颜色分离和稳定性，并且没有来自可染色纱线的颜色损失。
