    • The invention is directed to a detergent and a method of producing the same. The detergent is for textile surfaces and especially for textile floor coverings. The detergent includes a pulverized, porous carrier including a foamed, plastified urea-formaldehyde resin foam. The carrier material is enriched with detergent so that the finished product with respect to the carrier material has a weight per unit volume of 60 kg/m.sup.3 and an apparent density of 50 to 150 grams/liter; the granular size of the carrier material is between 0.01 and 12 mm; the surfactant containing water, which adheres to the carrier material, is stored in the carrier material in a completely homogeneous manner in a share of maximally 80% by weight referred to the weight of the carrier material; and, the detergent is produced from the mixture of the carrier material with a highly concentrated aqueous cleaning solution. The method includes the steps of foaming the plastified urea-formaldehyde resin foam; and, combining the free formaledhyde present during the manufacturing process prior to and/or during the foaming of the plastified urea-formaldehyde resin foam by adding formaldehyde binding substances and stabilizing substances to at least one of the solutions selected from the group consisting of the foaming agent solution and the resin solution.
    • 本发明涉及一种洗涤剂及其制造方法。 洗涤剂用于织物表面,特别是用于纺织品地板覆盖物。 洗涤剂包括粉碎的多孔载体,其包括发泡的,塑化的脲 - 甲醛树脂泡沫。 载体材料富含洗涤剂,使成品相对于载体材料的每单位体积的重量为60kg / m 3,表观密度为50至150克/升; 载体材料的粒度为0.01〜12mm; 附着在载体材料上的含有表面活性剂的水以完全均匀的方式储存在载体材料中,最大量为载体材料重量的80%(重量); 并且洗涤剂由载体材料与高度浓缩的水性清洗溶液的混合物制成。 该方法包括使增塑的脲醛树脂发泡体发泡的步骤; 并且通过向至少一种选自以下的溶液中加入甲醛结合物质和稳定物质,在塑化的脲 - 甲醛树脂泡沫的发泡之前和/或期间,在制造过程中存在的游离醛缩合物, 试剂溶液和树脂溶液。
