| titleOfInvention | Dimethylol carbamate derivatives and their use in treating fabrics |
| abstract | Dimethylol derivatives of a polyglycol ether carbamate having the formula <FORM:1123677/C3/1> wherein R is a C1- 18 alkyl group, an aryl group an alkaryl group or an aralkyl group, each R1 is hydrogen, a C1- 12 alkyl group, a C1- 4 haloalkyl or hydroxyalkyl group or the phenyl radical and x is 1-50 may be obtained by reacting a glycol ether of the formula <FORM:1123677/C3/2> (a) with urea; or (b) with phosgene and ammonia, and methylolating the product by treatment with formaldehyde in an aqueous alkaline solution. The glycol ether employed may be obtained in a conventional manner by the addition of an alkylene oxide to an hydroxy compound of the formula ROH.ALSO:Dimethylol derivatives of a glycol ether carbamate having the formula <FORM:1123677/C2/1> wherein R is a C1- 18 alkyl group, an aryl group an alkaryl group or an aralkyl group, each R1 is hydrogen, a C1- 12 alkyl group, a C1- 4 haloalkyl group, a C1- 4 hydroxyalkyl group or the phenyl radical and x is 1-50, may be obtained by reacting a glycol ether of the formula <FORM:1123677/C2/2> (a) with urea, or (b) with phosgene and ammonia, and methylolating the product by treatment with formaldehyde in an aqueous alkaline solution. Specific examples describe the preparation of N,N-dihydroxy methyl, diethylene glycol monomethyl ether carbamate and N,N-dihydroxymethyl ethoxyethyl carbamate.ALSO:Wash-wear properties are imparted to cellulosic fabrics by treatment with a cross-linking agent followed by curing at an elevated temperature wherein the cross-linking agent is a dimethylol derivative of a glycol ether carbamate of the formula: <FORM:1123677/D1-D2/1> where R is a C1-18 alkyl group, an aryl group, an alkaryl group or an aralkyl group, each R1 is hydrogen, a C1-12 alkyl group, a C1-4 haloalkyl or hydroxyalkyl group or the phenyl radical and X is from 1 to 50. Generally, the fabric is treated with an aqueous solution of from 5-20 wt. % of the cross-linking agent in the presence of an acidic catalyst followed by drying the fabric and then curing at 130-200 DEG C and the treated fabrics are stated to have improved chlorine resistance. In an example, a scoured, desized, bleached, cotton print cloth is treated. |
