Abstract
1362544 Treating wool G VERRI and A M VERRI 23 July 1971 [5 Aug 1970] 34665/71 Headings D1B and D1P A process for reducing the felting and shrinking properties of a material made of or containing wool, and bleaching the material and increasing its dye-receptivity, comprises contacting the material with a first aqueous alkaline oxidising bath and thereafter contacting the material with a second aqueous reducing bath, wherein: (a) the first bath comprises, from 4 to 6% of an alkali metal salt of pyrophosphate, from 2 to 3% of dicyandiamide, from 0.3 to 0.5% of a fatty alcohol ester or 0.1 % of sodium alginate as wetting agent, and either from 20 to 30% of an inorganic peroxide e.g. a 130 volume strength water solution of hydrogen peroxide, or from 10 to 20% of a water-soluble organic peroxide; and (b) the second bath comprises, at least one alkali metal salt of sulphurous acid or an alkali metal compound of sulphoxylic acid and optionally an alkali metal salt of pyrophosphoric acid, and a catalyst such as sodium bisulphite, all percentages being by weight based on the weight of the material. The first bath may further contain 0.1-0.2% sodium borohydride. The initial pH value of the first bath may be between 8.7 and 8.5, and that of the second bath between 7.5 and 5.5. The liquor ratios in each bath may lie in the range 1:10 to 1:25. The treatments in each bath may be effected at elevated temperature. Dyeing (pastel tints) may be effected by adding a vat or leucoester dye to the second bath, preferably together with 0.5% by weight based on the wool material of anhydrous piperazine, or 1 to 2% of 22Be ammonium hydroxide. The colours may be developed by treating the material in a further bath at a temperature of 40 to 50C and containing 3 to 6% by weight based on the wool material of 130 volume hydrogen peroxide, after which it is rinsed in dilute aqueous acetic acid solution and optionally with cold water, and dried. Alternatively the treatment in the second bath may be completed and the material rinsed in dilute acetic or formic acid, and the dyeing (bright shades) carried out subsequently. The wool material may be in form of tops, yarns, pieces, or bolts. An optical brightener may be incorporated in the second bath.
