摘要	A process for bleaching and finishing fibrous materials with a mixture containing salts of chlorous acid, polymerizable olefinically unsaturated compounds, small amounts of water and addition products of alkylene oxides on organic compounds which carry 1 to 10 active hydrogen atoms.
权利要求	1. A PROCESS FOR BLEACHING AND FINISHING FIBROUS MATERIALS WITH SALTS OF CHLOROUS ACID AND POLYMERIZABLE MONOMERS, WHICH COMPRISES APPLYING TO FIBROUS MATERIALS A COMPOSITION CONSISTING ESSENTIALLY OF A SALT OF CHLOROUS ACID AS POLYMERIZATION INITIATOR AND BLEACHING AGENT, A POLYMERIZABLE OLEFINICALLY UNSATURATED COMPOUND, 0.5 UP TO 80 PERCENT BY WEIGHT OF WATER AND AT LEAST I1 PERCENT BY WEIGHT OF A POLYOXYALKYLENE CONDENSATE OF AN ORGANIC COMPOUND HAVING 1 TO 10 ACTIVE HYDROGEN ATOMS WHICH CONDENSATE CONTAINS AT LEAST ONE ALKYLENE OXY RADICAL OF THE FORMULA -(CH(-R)-CH2-O)WHEREIN R IS HYDROGEN OR THE METHYL OR ETHYL GROUP, WITH RADICAL IS LINKED THROUGH AN OXYGEN OR NITROGEN ATOM TO THE ORGANIC COMPOUND HAVING THE ACTIVE HYDROGENS. 2. A process as claimed in claim 1, wherein the condensate of alkylene oxides and monovalent or bivalant organic compounds are used having the general formula I 3. A process as claimed in claim 1, wherein the bleaching and finishing mixture contains 20 to 75 percent by weight of the condensate of alkylene oxides on organic compounds. 4. A process as claimed in claim 1, wherein the bleaching and finishing mixture contains 0.2 to 60 percent by weight of the olefinically unsaturated compounds. 5. A process as claimed in claim 1, wherein the portion of water of the bleaching and finishing mixture is adjusted to less than 50 percent by weight. 6. A process as claimed in claim 1, wherein the bleaching and finishing operation is accelerated by the action of heat onto the fibrous materials before, during or after the application of the bleaching and finishing mixture. 7. A process as claimed in claim 1, wherein esters of the sulfuric, phosphoric or carboxylic acid of the condensate of alkylene oxides are used. 8. A process as claimed in claim 1, wherein the alkali metal or alkaline earth metal salts of the chlorous acid are present in the bleaching mixture in a concentration of from about 0.05 to about 20 percent by weight. 9. A process as claimed in claim 1, wherein the condensate of alkylene oxides on organic compounds carrying 1 to 10 active hydrogen atoms which are liquid at room temperature, are used. 10. A process as claimed in claim 1, wherein the bleaching and finishing mixture is applied to the fibrous material in the form of a foam. 11. A process as claimed in claim 1, wherein the bleaching and finishing mixture additionally contains an inert organic solvent.
