    • Methodologies and equipment for using a hypochlorite solution to remove menstrual fluid, underarm perspiration or other hard-to-remove stains from soft fabric articles with reduced damage to the fabric articles when compared with popular chlorine bleaches. The soft fabric articles preferably are in white, although the present invention can also be applied to articles in other colors. In one embodiment, the weight concentration ratio of the alkali metal hydroxide over the hypochlorite salt in the hypochlorite solution is no less than 1:12.5. The hypochlorite solution may contain at least 0.2% by weight of sodium hydroxide and/or have a pH of at least 11.8.
    • 使用次氯酸盐溶液从流行的氯漂白剂中减少对织物制品的损伤,使用次氯酸盐溶液从柔软的织物制品中除去月经液,腋下汗水或其他难以除去的污渍。 柔软的织物制品优选是白色的,尽管本发明也可以应用于其它颜色的制品。 在一个实施方案中,碱金属氢氧化物与次氯酸盐溶液中次氯酸盐的重量浓度比不小于1:12.5。 次氯酸盐溶液可以含有至少0.2重量%的氢氧化钠和/或具有至少11.8的pH。

    • 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.
    • 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。
