Abstract: A process for preparing low-salt preparations of condensation products based onA) sulphonated aromatics,B) aldehydes and/or ketones and optionallyC) one or more compounds selected from the group consisting of nonsulphonated aromatics, urea and urea derivatives,characterized in that inorganic acid present after the condensation is separated off in whole or in part from the condensation product, optionally in the form of its salts after neutralization, until the inorganic salt content is less than 10% by weight, relative to the preparation, leads to preparations which are outstandingly suitable as tanning agents, dispersants and liquefiers.

Abstract: If the edge of a filter cloth is coated with one or more layers of a polychloroprene latex mixture which contains zinc oxide and a silicate filler in addition to a polychloroprene with carboxyl groups, sticking is so greatly reduced that the durability of the filter cloths is substantially increased.

Abstract translation: 如果滤布的边缘除了具有羧基的聚氯丁二烯之外还涂覆有一层或多层含有氧化锌和硅酸盐填料的聚氯丁二烯胶乳混合物，粘合力大大降低，使得滤布的耐久性基本上 增加。
