| abstract | Fabrics are printed to form a glazed design which may be coloured or not by employing a printing paste containing melamine formaldehyde resin, or homologues thereof. The resin is the condensation product formed by combining 1-5 molecular parts of aqueous formaldehyde with 1 part of melamine in alkaline solution. The resin is made into a paste by mixing 75 parts by weight of cornstalk paste, formed by cooking .75 lbs. of cornstalk in one gallon of water, with 15 parts by weight of melamine formaldehyde and 10 parts by weight of a 10 per cent solution of ammonium chloride. A plasticiser such as di-butyl phthalate may be added. A gum tragacanth paste or a protein thickener may be employed. After printing, the fabric is dried at a temperature insufficient to polymerize the resin, and is polished by means of heated calendering rolls. The fabric is then subject to a heat treatment to complete any polymerization of the resin caused by the drying process, a treatment at between 290-300 DEG F. for five minutes may be used. The fabric is finished by a washing process which removes the glaze except at the printed portions which thus appear on the fabric as a glazed coloured or plain design, which may resemble a figured weave. |
