Abstract

Vegetable fibres are contacted with an alkaline peroxide solution when at a temperature above 100 DEG C. and under a pressure above atmospheric pressure. The fibres may be saturated with an aqueous solution of an alkali and a peroxide stabilizer and hydrogen or sodium peroxide may be added when the temperature of the first solution is above 100 DEG C., or the fibres may be saturated with an unneutralized, acid solution of hydrogen peroxide and an alkali and a peroxide stabilizer added when the temperature of the first solution is above 100 DEG C. The fibres may be cheeses, beams or other packages of cotton and linen. The pressure does not exceed that at which the liquid is required to boil, and the liquid may be at the boiling temperature. In an example, cotton yarn is immersed in a solution containing magnesium sulphate, sodium silicate and sodium hydroxide and a mixture of sodium salts of secondary alkyl sulphates containing 12 to 18 carbon atoms in the molecule, in a vessel equipped with a blow off valve set to operate at a temperature of 120 DEG C. When this temperature is reached, hydrogen peroxide is added. Specification 490,382 is referred to.
