Abstract

DC60 (08/08/49) The pattern conductor for textile transfer printing consists of paper with an air permeability (Bentzen porosity) greater than 500 ml/min and a water absorption corresponding to at least Cobb number 50. This paper is coated with an aqueous dispersion of carboxymethyl cellulose containing non-crystalline saccharide syrup, ideally at a concentration of approximately 30 g/m². One or more color patterns are then printed on this paper. Each color pattern consists of a water-soluble or water-dispersible pigment mixed with a thickening conductor that is easily soluble by a temporary adhesion effect, ideally in the form of carboxymethyl cellulose. The use of saccharide syrup, preferably sorbitol syrup for coating, makes it possible to use unprocessed paper with standard absorption as the basis of the pattern conductor, which provides a cost advantage. The clear cost and production advantages of the pattern carrier for textile transfer printing consist of paper with an air permeability (Bentsen porosity) greater than 500 ml/min and a water absorption corresponding to a Cobb number of at least 50. This paper is coated with carboxymethyl cellulose dispersed in an aqueous solution containing non-crystalline saccharide syrup, ideally at a dispersion rate of approximately 30 g/m². One or more color patterns are then printed on this paper. Each color pattern consists of a water-soluble or water-dispersible pigment mixed with a thickening agent that is easily soluble by a temporary adhesion effect, ideally in the form of carboxymethyl cellulose. The use of saccharide syrup, preferably sorbitol syrup, for coating makes it possible to use unprocessed paper with standard absorption as the pattern carrier base, providing clear cost and production advantages.

Claims (5)

1. A pattern carrier in the form of a paper membrane with the printed color pattern on top is used for transfer printing of patterns onto a moist textile membrane by compressing two membranes between one or more pairs of rollers without heat, but under linear pressure. The textile membrane is compressed along its short length until its thickness decreases, followed by natural expansion. The color pattern is absorbed from the pattern carrier into the textile membrane. The pattern carrier is made of paper with an air permeability (Bentsen porosity) greater than 500 mL/min, measured according to DIN 53120 TI, and a water absorption rate corresponding to at least 50 Cobb numbers measured according to SCAN-P12:64 Cobb 60. This paper is coated with carbohydrate-methylcellulose dispersed in an aqueous solution containing non-crystalline saccharide syrup, ideally at a dispersion rate of approximately 30 g/m². One or more color patterns are then printed onto this paper. Each color pattern consists of water-soluble or water-dispersible pigments mixed with a readily soluble thickening agent that exhibits temporary adhesion, ideally in the form of carbohydrate cellulose. 2. A pattern carrier under claim 1, characterized by the use of a saccharide syrup containing sorbitol as the main ingredient. 3. The pattern carrier under claim 2 is characterized by the fact that the saccharide syrup used, other than sorbitol, contains mannitol and a small amount of reducing sugar. 4. A pattern carrier according to claim 3, characterized by the use of saccharide syrup providing approximately 20% by weight distribution. 5. The use of non-crystalline saccharide syrup as a dispersion ingredient in an aqueous solution for coating paper pulp to obtain a pattern conductor with a surface that can immediately drain moisture derivatives from printing pigments while the pigments remain on the surface along with carboxymethylcellulose.
