Abstract
A glazed chintz effect is produced and rendered permanent upon a textile fabric by applying a melamine-aldehyde resin condensation product liquor to the surface of a fabric which has already been subjected to a preliminary glazing by friction calendering, drying the resin-coated fabric, subjecting it to further friction calendering, and curing the resin. The melamine resin is cured by baking or by leaving the fabric for some time at ordinary or elevated temperature, if desired in presence of a catalyst. Furfural may be included as an ingredient in the preparation of the resin. Hardening of the resin is facilitated by including resorcinol in the resinous liquor. Hardening may thus be effected in the absence of acid or alkaline catalysts and without heating. The resorcinal reacts with the melamine-formaldehyde condensation product and with any free formaldehyde present to form a mixed resorcinol - melamine - formaldehyde resin. The amount of resorcinol added may be 10-50 per cent of the weight of the melamine resin liquor. A melamine-formaldehyde liquor may be obtained by mixing 63 parts of melamine with 112 parts of formalin (40 per cent) adjusted to pH 7, keeping the mixture at 60-70 DEG C. until the solution is clear and then boiling for 30 minutes. After cooling 1 per cent of citric or tartaric acid is added in the minimum amount of water. The resin may be modified by adding 30 parts of furfural before or after boiling. The resin liquor may also be obtained by mixing 10 parts of powdered melamine-formaldehyde resin with 30 parts of water and boiling for 10 minutes, 5 parts of furfural being added just before the mixture comes to the boil. After cooling 0.1 parts of citric or tartaric acid are added. A resorcinol-modified resin liquor may be obtained by mixing 63 parts of melamine and 112 parts of formalin (63 per cent), heating until a clear solution is obtained, boiling, cooling, and just before using, adding resorcinol in the amount of 20 per cent of the liquor.ALSO:A glazed chintz effect is produced and rendered permanent upon a textile fabric by applying a melamine-aldehyde resin condensation product liquor to the surface of a fabric which has already been subjected to a preliminary glazing by friction calendering, drying the resin-coated fabric, subjecting it to further friction calendering, and curing the resin. The melamine resin is cured by baking or by leaving the fabric for some time at ordinary or elevated temperature, if desired in presence of a catalyst. Furfural may be included as an ingredient in the preparation of the resin. Hardening of the resin is faciliated by including resorcinol in the resinous liquor. Hardening may thus be effected in the absence of acid or alkaline catalysts and without heating. The recorcinol reacts with the melamine-formaldehyde condensation product and with any free formaldehyde present to form a mixed resorcinol-melamine-formaldehyde resin. The amount of resorcinol added may be 10-50 per cent of the weight of the melamine resin liquor. Cloth which has been initially glazed by friction calendering is treated with the resin liquor by roller-coating, and is dried and friction calendered. The glazed chintz is then baked at 140 DEG C., or left for a prolonged period to allow curing to occur at ordinary temperature.
