    • A preparation for shrinkproofing wool composed of:(a) 1 to 50 weight percent of organopolysiloxanes, which are built up from(a.sub.1) 90 to 99.8 mole percent of units of formula R.sub.2.sup.1 SiO, and(a.sub.2) 0.2 to 10 mole percent of units of the formula R.sup.2 SiO.sub.1.5 in whichR.sup.1 and R.sup.2 consist of 0.1 to 10 mole percent of polyoxyalkylene residues and, on the other hand, of 0.03 to 3 mole percent of mercaptoalkyl or mercaptoaryl residues, and/or 0.06 to 6 mole percent of aminoalkyl residues and/or 0.1 to 10 mole percent of anionic groups, which are linked to silicon atoms through carbon atoms,the remaining portion of R.sup.1 and R.sup.2 groups being methyl groups, up to 10 mole percent of which however may be replaced by alkyl residues of longer chain length, by aryl residues or by hydrogen atoms, while at the same time up to 5 mole percent of the oxygen atoms, which are liked to silicon, may in each case be replaced by two lower alkoxy or hydroxy groups, and(b) 50 to 99 weight percent of water and/or organic solvents. Wool, treated with this preparation, retains its resistance to shrinking even after repeated launderings. The hand of the wool and the hand of knitted and woven fabrics produced from the wool is not affected.
    • 一种用于防缩羊毛的制剂,其由以下组分组成:(a)1至50重量%的由(a1)90至99.8摩尔%的式R21SiO的单元构成的有机聚硅氧烷,和(a2)0.2至10摩尔% 式R2SiO1.5,其中R1和R2由0.1至10摩尔%的聚氧化烯残基组成,另一方面为0.03至3摩尔%的巯基烷基或巯基芳基残基,和/或0.06至6摩尔%的氨基烷基残基 和/或0.1至10摩尔%的阴离子基团,其通过碳原子连接到硅原子上,R 1和R 2基团的剩余部分是甲基,最多10摩尔%可以被更长的烷基残基所取代 链长,芳基残基或氢原子,而同时高达5摩尔百分比的硅原子,可以在两种情况下被两个低级烷氧基或羟基取代,(b) 50至99重量%的水和/或有机溶剂 呃 用这种制剂处理的羊毛,即使在重复洗涤之后仍保持其收缩的抗性。 由羊毛生产的针织和梭织布的羊毛和手的手不受影响。
