The present invention provides a method for providing a printed article, comprising printing an aqueous ink composition onto a fibrous substrate and curing the ink, wherein the ink composition comprises a polyurethane dispersion having the properties of (a) ketone or aldehyde groups present at one or more polymer chain ends; (b) a number average molecular weight ≤50,000 and; (c) the content of ketone and aldehyde groups is in the range 0.02 to 4.0 mmol g-1, based on the dry polymer weight. The present invention also provides use of said ink composition for printing onto a fibrous substrate.

A sprayable and hygroscopic ink for a digital printing process on a fabric includes 3.0 parts by weight to 6.0 parts by weight of a colorant, 0.5 parts by weight to 2.0 parts by weight of a hygroscopic agent, 0.5 parts by weight to 1.0 part by weight of a surfactant, and a balance of a solvent, in which a pH value of the hygroscopic agent is between 6.0 and 8.5 at 25° C., and a particle diameter D90 of the sprayable and hygroscopic ink is between 180 nm and 220 nm.

The invention relates to cushioned rugs comprising polyester yarn, particularly polyethylene terephthalate (PET) yarn, comprising a crystallinity-reducing modifier in the polyester yarn, such as a branched polyester modifier. The invention further relates to methods of preparing such cushioned rugs.

A waterless dyeing device for cone yarn, a waterless dyeing method and a produce are provided; wherein the device comprising: a dye autoclave (1); a dyeing autoclave (2); a recycle autoclave (6); a dyeing circulation system in which the dye autoclave (1), the dyeing autoclave (2) and the recycle autoclave (6) are in fluid communication with; wherein further comprises: a cone yarn inlet formed on the top of the dyeing autoclave (2), which is provided with a sealing cap (7); a cone yarn center shaft (10) vertically disposed at the center inside the dyeing autoclave, which is a perforated outlet tube with fluid discharge holes opened on the side wall; an intake pipe (13) disposed on the bottom of the dying autoclave (2) which is in communication with the cone yarn center shaft (10); a dyeing autoclave outlet (9) disposed on the dying autoclave (2); and a CO2 container (4), a pressure pump, a circulation pump (3) and conduits which are included in the dyeing circulation system. The dyes are disposed in the dye autoclave (1) and the cone yarns are disposed inside the dyeing autoclave (2), CO2 is introduced into the dye autoclave (1) to dissolve the dyes gradually, and the CO2 carrying the dyes to the dyeing autoclave (2) to dye and diffuse. The present invention has the advantages of being high in production efficiency, even in dyeing effect and high in safety, and is suitable for waterless dyeing of polyester cone yarns.
