Textile soaps Patent

Patent Textile Soaps.—Stockhausen (Eng. Pat. 24,868, 1897) makes special claim for a soap, termed Monopole Soap, to be used in place of Turkey-red oils in the dyeing and printing of cotton goods and finishing of textile fabrics. The soap is prepared by heating the sulphonated oil (obtained on treatment of castor oil with sulphuric acid) with alkali, and it is stated that the product is not precipitated when used in the dye-bath as is ordinary soap, nor is it deposited upon the fibres.

An enormous number of different compounds have been prepared (11-33, see Table 28.1), but of all the possibilities mentioned in hundreds of patents, only a few are used in the industry. The different compounds used in industry have considerable effect on such properties as solubility and exhaustion rate at different temperatures and on the use of the products on a wide variety of materials. The range extends from readily water-soluble whiteners for paper to textile and soap and detergent whiteners to whiteners for polyamide fibers in the mass.
