Abstract: Fibrous material containing at least 33% by weight of cellulosic material is cross-linked b reaction with a compound containing at least two vinyloxy groups defined as groups of formula <FORM:1005731/C3/1> where R1, R2 and R3 are hydrogen atoms or alkyl groups.  The fibrous material, e.g. filaments, fibres, yarns, threads or fabrics are thereby rot-proofed and show improved crease resistance.  The vinyloxy compound may be applied by impregnating the fabrics &c., as by padding, with a solution or suspension of the vinyloxy compound in an inert diluent such as dimethyl formamide or a mixture of dimethyl formamide and the diethyl ether of diethylene glycol, in presence of hydrochloric or sulphuric acid.  The impregnated material may then be allowed to stand at ambient temperature, or may be heated, before being washed with water and dried at ambient temperature.  Preferred vinyloxy compounds are <FORM:1005731/C3/2> where R1, R2 and R3 are hydrogen atoms or alkyl radicals, and Z is a divalent organic radical such as -(CR21)n; (CR21)n-CH=CH (CH21)n-; or -(CR21)n -[O-(CR21)2]O (CR21)2- where n is an integer and R1 is hydrogen atom or a substituted or unsubstituted alkyl radical. Specified vinyloxy compounds are 1,3-divinyloxypropane, 1,5-divinyloxypentane, 1,4 - divinyloxybutane, divinylethers of diethylene glycol and triethylene glycol, 1,2,3-trivinyloxypropane, dipropylene glycol divinylether, 1,4 - divinyloxy - cyclohexane, neopentyl glycol divinyl ether, thiodiglycol divinyl ether and acrolein dimer.ALSO:Fibrous material containing at least 33% by weight of cellulosic material is cross-linked by reaction with a compound containing at least two vinyloxy groups defined as groups of formula <FORM:1005731/D1-D2/1> where R1, R2 and R3 and hydrogen atoms or alkyl groups.  The fibrous material e.g. filaments, fibres, yarns, threads or fabrics are thereby rot-proofed and show improved crease resistance.  The vinyloxy compound may be applied by impregnating the fabrics &c., as by padding, with a solution or suspension of the vinyloxy compound in an inert diluent such as dimethyl formamide or a mixture or dimethyl formamide and the diethyl other of diethylene glycol, in presence of hydrochloric or sulphuric acid.  The impregnated material may then be allowed to stand at ambient temperature, or may be heated, before being washed with water and dried at ambient temperature.  Preferred vinyloxy compounds are <FORM:1005731/D1-D2/2> where R1, R2 and R3 are hydrogen atoms or alkyl radicals, and Z is a divalent organic radical such as <FORM:1005731/D1-D2/3> or <FORM:1005731/D1-D2/4> where n is an integer and R1 is a hydrogen atom or a substituted or unsubstituted alkyl radical.  Specified vinyloxy compounds are 1, 3-divinyloxypropane, 1, 5-divinyloxypentane, 1, 4-divinyloxybutane, divinylethers of diethylene glycol and triethylene glycol, 1, 2, 3-trivinyloxypropane, dipropylene glycol divinylether, 1, 4-divinyloxy-cyclchexane, neopentyl glycol divinyl ether, thiodiglycol divinyl ether and acrolein dimer.  In examples, cotton poplin and cotton/nylon poplinette are treated.ALSO:Fibrous material containing at least 33% by weight of cellulosic material is cross-linked by reaction with a compound containing at least two vinyloxy groups defined as groups of formula <FORM:1005731/A5-A6/1> where R1, R2 and R3 are hydrogen atoms or alkyl groups.  The fibrous material e.g. filaments, fibres, yarn, threads or fabrics are thereby rotproofed and show improved crease resistance.  The vinyloxy compound may be applied by impregnating the fabrics etc., as by padding, with a solution or suspension of the vinyloxy compound in an inert diluent such as dimethyl formamide or a mixture of dimethyl formamide and the diethyl ether of diethylene glycol, in presence of hydrochloric or sulphuric acid.  The impregnated material may then be allowed to stand at ambient temperature, or may be heated, before being washed with water and dried at ambient temperature.  Preferred vinyloxy compounds are <FORM:1005731/A5-A6/2> where R1, R2 and R3 are hydrogen atoms or alkyl p  radicals, and Z is a divalent organic radical such as <FORM:1005731/A5-A6/3> or <FORM:1005731/A5-A6/4> where n is an integer and R1 is a hydrogen atom or a substituted or unsubstituted alkyl radical.  Specified vinyloxy compounds are 1, 3-divinyloxypropane, 1, 5-divinyloxy-pentane, 1, 4-divinyloxybutane, divinylethers of diethylene glycol and triethylene glycol, 1, 2, 3-trivinyloxypropane, dipropylene glycol divinylether, 1, 4-divinyloxy-cyclohexane, neopentyl glycol divinyl ether, thiodiylycol divinyl ether and acrolein dimer.
