Abstract
A composition comprising a mixture of a curable urea-aldehyde resin or other crosslinking agent and a nitroalkanol or nitroalkane and having particular utility for treating textiles and non-woven cellulose products to provide permanent press and wrinkle-resistant characteristics.
Claims32
A method of preparing a wrinkle-resistant fabric by the steps of (a) impregnating the fabric with a curable urea-formaldehyde resin and a catalyst therefor and from 0.25 to 3.0 moles of a nitroalkanol per mole of urea, said nitroalkanol being represented by the formula ##STR4## where R and R.sup.1 are hydrogen, methyl, ethyl or hydroxymethyl and can be the same or different and (b) heating to 225.degree. F. to 350.degree. F. to effect a cure of the resin.
A method of preparing a wrinkle-resistant fabric by the steps of (a) impregnating the fabric with a composition comprising a curable urea-formaldehyde resin and an acid catalyst therefor and a nitroalkane of 1 to 3 carbon atoms or mixture thereof in a mole ratio of from 0.25 to 3.0 per mole of urea and (b) heating to 225.degree. F. to 350.degree. F. to effect a cure of the resin.
A method of reducing residual aldehyde on a product when treated with a urea-aldehyde resin and heated to cure the resin comprising the step of treating the product prior to the heating step with a nitroalkanol corresponding to the formula ##STR5## where R and R.sup.1 are hydrogen, methyl, ethyl or hydroxymethyl and can be the same or different.
A method of preparing a wrinkle-resistant fabric by the steps of (a) impregnating the fabric with a composition comprising a cross-linking agent and a nitroalkanol of the formula ##STR6## where R and R.sup.1 are hydrogen, methyl, ethyl or hydroxymethyl and can be the same or different, or a mixture thereof and (b) heating to 225.degree. F. to 350.degree. F. to effect a cure.
A method of preparing a wrinkle-resistant fabric by the steps of (a) impregnating the fabric with a composition comprising a cross-linking agent adapted to conferring wrinkle resistance and durable press properties, an acidic catalyst and a nitroalkane of 1 to 3 carbon atoms, or a mixture thereof and (b) heating to 225.degree. F. to 350.degree. F. to effect a cure of the resin.
