Abstract
A cloth for textile printing, wherein any of the following substances is present on the surface of or in the interior of the cloth, (a) a tertiary amine compound having either a carboxyl group or a sulfonic group in its molecule, or a salt thereof, (b) a compound having a carboxyl group and an amide group, or a salt thereof, and (c) a compound having a sulfonic group and an amide group, or a salt thereof.
Claims6
A textile printing process comprising the steps of:
- (i) providing a cloth comprising cotton or silk fiber and containing at least one substance selected from the group consisting of pyridine-3-carboxylic acid, dimethylglycine, bishydroxyethyltaurine, hippuric acid, glutamic acid, benzoyltaurine, alkali metal salts thereof and organic amine salts thereof on the surface of or in the interior of the cloth;
- (ii) applying an ink comprising a reactive dye on the cloth by an ink-jet systems;
- (iii) reacting the fiber with the dye in the ink applied on the cloth in step (ii);
- and
- (iv) washing the cloth resulting from step (iii).
A printed cloth comprising cotton or silk fiber, containing a reactive dye and at least one substance selected from the group consisting of pyridine-3-carboxylic acid, bishydroxyethyltaurine, hippuric acid, benzoyltaurine, alkali metal salts thereof and organic amine salts thereof on the surface of or in the interior of the printed cloth.
A process for alleviating bleed in a multi-color print on a cloth comprising cotton fiber or silk fiber, the multi-color print formed by a textile printing process comprising the steps of:
- (i) applying an ink containing a reactive dye on the cloth by an ink-jet system;
- (ii) reacting the dye in the ink applied on the cloth with the fiber;
- and
- (iii) washing the cloth resulting from step (ii);
- wherein the cloth used in step (i) contains at least one substance selected from the group consisting of pyridine-3-carboxylic acid, dimethylglycine, bishydroxyethyltaurine, hippuric acid, glutamic acid, benzoyltaurine, alkali metal salts thereof and organic amine salts thereof on the surface of or in the interior of the cloth.
A printed cloth comprising cotton or silk fiber, containing a reactive dye and at least one substance selected from the group consisting of pyridine-3-carboxylic acid, bishydroxyethyltaurine, hippuric acid, benzoyltaurine, alkali metal salts thereof and organic amine salts thereof on the surface of or in the interior of the printed cloth, the cloth being obtained by a process comprising the steps of:
- (i) providing the cloth;
- (ii) applying to the cloth at least one substance from the group consisting of pyridine-3-carboxylic acid, bishydroxyethyltaurine, hippuric acid, benzoyltaurine, alkali metal salts thereof and organic amine salts thereof, and then drying the cloth;
- and
- (iii) applying an ink containing the reactive dye to the cloth resulting from step (ii).
