摘要:
Provided is a treatment agent used for forming an image on fabric, containing a resin emulsion and a metal salt. A pH of the treatment agent is in a range from 5.5 to 9. The pH may be adjusted using a pH adjuster. Examples of the pH adjuster include sodium bicarbonate, potassium carbonate, calcium carbonate, sodium hydroxide, sodium carbonate, triethanolamine, and N-butyl diethanolamine.

The present invention claims dyestuffs of the formula I wherein D, R1 to R5, m and n are defined as given in claimi, a process for their preparation, their use and and inks for ink jet printing containing them.
摘要:
A digital printing machine prints textiles. The machine comprises a wetting unit for wetting fabric to be printed prior to printing, a printing head for printing on said fabric and a flattening unit located between the wetting unit and the printing head for exerting pressure on the fabric to flatten outwardly extending fibers of the fabric after wetting and before printing. The flattening provides a smoothed surface for digital printing.

Provided is a pretreatment liquid for use on a fabric prior to printing with ink on the fabric, the pretreatment liquid comprising: water; polyvalent metal ions; and first fine polymer particles,
wherein the first fine polymer particles are crosslinkable polyurethane and/or crosslinkable polyurethane-polyurea, the particles having a glass transition temperature of -10°C or lower and a particle diameter as determined by a light scattering method of 30 nm to 5 µm.
摘要:
Provided is an image forming method for forming an image on fabric including a treatment step of applying a treatment agent on fabric, an image printing step of printing an image on a treatment agent-applied area with an ink, and a heat-fixing step of heat-fixing the ink on the fabric. The treatment agent used in the treatment step includes at least one of the following component A and the following component B: Component A: a diallyldimethylammonium chloride-sulfur dioxide copolymer Component B: a mixture of an allylamine-diallylamine copolymer and sodium chloride.
摘要:
Dye mixtures comprising at least one dye of formula (1) together with at least one dye from the group of formulae (2), (3) and (4), wherein the radicals have the definitions given in the claims, are suitable for dyeing or printing cellulose-containing fibre materials, while at the same time exhibiting good build-up behaviour, and yield dyeings of deep shade having good fastness properties.
摘要:
[PROBLEMS] To provide a method of inkjet textile printing which eliminates needs for steaming treatment and washing treatment which are inevitable in a conventional method of inkjet textile printing. [MEANS FOR SOLVING THE PROBLEMS] A method of inkjet textile printing using an aqueous ink, comprising: an ejection step of ejecting said aqueous ink relative to a textile medium in an inkjet method; and a microwave radiation step of radiating microwaves to said textile medium having said aqueous ink ejected thereon, wherein said aqueous ink contains: water; an anionic dye including an acid dye or a reactive dye; a polyhydric alcohol; and a compound having a behavior of promoting the fixing of coloring agent relative to said textile medium when said textile medium having the ink ejected thereon is irradiated with microwaves.
