Abstract
In the process of the parent Specification in which formaldehyde is reacted with the adduct of an epihalogenhydrin and a resin forming amino compound, two improvements are described: (1) the reaction is effected in the presence of a hydroxide of Ca, Ba, Mg or Sr, and (2) the methylol groups of the reaction product are alkylated with an aliphatic hydrocarbon radical of C1-6. Urea and/or melamine are the only amino-compounds disclosed, and epichlorohydrin is the only epihalohydrin. In process (2) the formaldehyde reaction may have been carried out in the presence of NaOH, and if phosphoric acid is used as the subsequent alkylating catalyst, the resultant sodium phosphate may be filtered off; HCl is also mentioned as an alkylating catalyst. Aqueous solutions of the products of either improved process are used to impregnate cellulosic textile material (see Group IV(c)), in which case MgCl2 may be added as a hardener. In the examples the amino compound and the epihalohydrin are reacted in aqueous solution and the formaldehyde is in aqueous or methanolic solution.ALSO:In the process of the parent Specification in which formaldehyde is reacted with the adduct of an epihalogenhydrin and a resin forming amino compound, two improvements are described:-(i) the reaction is effected in the presence of a hydroxide of Ca, Ba, Mg or Sr, and (ii) the methylol groups of the reaction product are alkylated with an aliphatic hydrocarbon radical of C1-C6. Urea and/or melamine are the only amino compounds disclosed, and epichlorohydrin is the only epihalohydrin. In process (ii) the formaldehyde reaction may have been carried out in the presence of NaOH, and if phosphoric acid is used as the subsequent alkylating catalyst, the resultant sodium phosphate may be filtered off; HCl is also mentioned as an alkylating catalyst. Aqueous solutions of the products of either improved process (see Group IV(a)) may be used to impregnate cellulosic textile materials (see Group IV(c)). In the examples the amino compound and the epihalohydrin are reacted in aqueous solution and the formaldehyde is in aqueous or methanolic solution.ALSO:Cellulosic textile materials, e.g. cellulose, regenerated cellulose, modified cellulose and viscose rayon staple which has never been dried, may be impregnated with an aqueous solution of a stable, water-soluble, aminoplast precondensate described below, and heated to insolubilize the resin and reduce the water imbibition of the impregnated material. The precondensates are modified forms of the reaction products of formaldehyde with the adduct of an epihalogenhydrin and a resin-forming amino-compound of the parent Specification. The modifications are either in the catalyst (see Groups IV(a) and IV(b)) or in that the methylol groups of the reaction product are alkylated with an aliphatic C1-6 hydrocarbon radical. Urea and/or melamine are the only amino compounds disclosed, and epichlorohydrin is the only epithalohydrin. Magnesium chloride may be added as a catalyst. Examples are given.
