摘要:
Disclosed is a process for printing on polyester fabric comprising (1) contacting polyester fabric with an aqueous solution comprising (A) 5% to 35% by weight of at least one multivalent cationic salt; (B) 0.1% to 5% by weight of a blocked polyisocyanate crosslinking agent, and (C) 3% to 40% by weight of a waterborne resin, all percentages based on the weight of the aqueous solution; (2) drying the polyester fabric to remove the water from the polyester fabric; and (3) digitally printing the pretreated and coated polyester fabric with a water-based textile ink.
摘要:
Method for inkjet textile printing comprising a printing step for printing an aqueous pigment ink on a specifically pretreated portion of a textile fiber product by an inkjet process,wherein said specific pretreatment is performed by applying at least: (A) a quaternary ammonium salt type cationic surfactant represented by the formula (1) below, and (B) a block isocyanate compound to the entire textile fiber product or a required portion thereof, and said aqueous pigment ink comprises at least a pigment, an aqueous liquid as a solvent or dispersion medium, and: (C) a water-soluble dispersing agent having a crosslinking property, (D) a self-emulsifying type urethane resin, and (E) a block isocyanate compound. [Two of R1 to R4: alkyl having 8 to 18 carbon atoms; the remaining two: methyl or ethyl; X−: anion.]
摘要:
An ink jet ink composition for textile printing contains a crosslinking component having a blocked isocyanate group, tertiary amine, at least one carboxylic acid selected from the group consisting of monocarboxylic acid, dicarboxylic acid, and tricarboxylic acid, a pigment, and water.
摘要:
A process for improving characteristics such as, whiteness retention, degradation, and dyeability of a polyamide by contacting the polyamide with thiocyanate. A polyamide produced by the process has improved dyed color depth, dyed color uniformity, hue, elimination of light dyeing ends, protection of dye sites from degradation, protection from UV degradation, reduced yellowing or oxidation, and/or resistance to loss of dyeability.

摘要:
The invention relates to a process for the manufacture of prints which are fast to wet processings and sublimation on textile or non-textile sheets by means of the transfer printing process, wherein dyestuffs containing mercapto, hydroxyl and/or amino groups and applied to sheets by means of the transfer printing process are fixed by the action of isocyanates or masked isocyanates, which are applied to the sheets before, during, or after the dyestuff transfer.
