IN WHICH R is alkylene, R'' hydrogen, methyl or ethyl, q at least 1 and either m is zero, when n and p each are also zero or m is 1, when n is zero or 1 and p is 1. Afterwards the polysulfide is cured on the material.
A process for modifying keratinous material, and, in particular for rendering the material resistant to shrinkage and for imparting durable press characteristics to the material is provided. The material is treated with a polysuflide of the formula
摘要:
A discrete, well defined pattern is produced on colored fabric by applying to the desired area of the fabric a viscous mixture of fine mineral particles, water and one or more bleaching agents. The viscous mixture remains confined to the designated area and permeates the fabric. After a controlled, finite period of time, the mixture is rinsed away, leaving a well defined area from which the fabric coloration has been removed.
摘要:
A process for the treatment of textile materials consisting of or containing natural vegetable or animal fibres, in which (a) ketatolytic liquid is allowed to act on the textile material, and then washed out, then preferably the material is further treated with an oxidizing agent which thereafter is washed out, (b) the textile material is impregnated with a suspension of a finely-divided frit or glazing powder, and (c) the impregnated material is subjected to heat-treatment at a temperature of above 180.degree. C.
摘要:
A process for the treatment of natural and/or synthetic fibrous and filamentary materials, including living human hair, which involves applying to the fibrous or filamentary materials a polymeric compound containing at least one poly (oxyalkylene) or polyamide chain and at least one thiosulphuric acid or thiosulphate group. Such compounds having more than one thiosulphuric acid or thiosulphate group are curable and can be used with advantage in textile finishing, for example in the pigment dyeing and printing of fibrous materials including pure synthetic fibres, in application to fibres or fabrics to impart shape stabilisation, in application to keratinous fabrics to impart shrink resist properties and for the flat setting and permanent creasing of fabrics, and to impart antistatic properties to fibres and filaments. Hair may be treated according to the invention to improve its handle and for permanent waving and setting.
摘要:
This invention relates to a process for modifying keratinous material, and, in particular, to a process for rendering the material resistant to shrinkage and to a process for imparting durable press characteristics to the material. This process comprises treating the material with a resin having at least two thiol groups per molecule and containing a radical of a polyhydric alcohol, bound to this radical, at least two poly(oxyalkylene) chains, at least two radicals of a thiolcontaining aliphatic carboxylic acid or of a thiol-containing aliphatic alcohol. As curing catalyst a sulfur-containing organic compound is used.
摘要:
A simple and economical one-step process for felt-proofing and dimensionally stabilizing textiles, particularly textiles based on keratinous fibers is disclosed. In the process, the textiles are treated with aqueous baths which contain salts of sulfurous acid or pyrosulphites as reducing agents and polyurethanes which contain onium groups.
