An example of an inkjet pre-treatment fluid for dye sublimation printing consists of a humectant; a cationic polymer; a surfactant; a co-solvent present in an amount up to about 50 wt % based on a total weight of the inkjet pre-treatment fluid; and a balance of water. In an example of a printing method, the inkjet pre-treatment fluid is inkjet printed onto a textile substrate to form a pre-treated area on the textile substrate.

An ink set for ink jet containing yellow ink containing C.I. Disperse Yellow 65, a magenta ink containing C.I. Disperse Red 362, and a cyan ink containing C.I. Disperse Blue 60.

An example dye sublimation inkjet ink set includes a first dye sublimation inkjet ink and a second dye sublimation inkjet ink. The first dye sublimation inkjet ink includes a disperse dye colorant dispersion including a first disperse dye having absorption at a radiation wavelength ranging from about 360 nm to about 410 nm; an additive to absorb energy at the radiation wavelength ranging from about 360 nm to about 410 nm and to dissipate at least some of the absorbed energy as fluorescence; a co-solvent; and a balance of water. The additive is selected from the group consisting of a compound containing from 3 to 5 fused benzene rings and and a coumarin derivative. The second dye sublimation inkjet ink includes a disperse dye colorant dispersion including a second disperse dye having less absorption at the radiation wavelength than the first disperse dye; a co-solvent; and a balance of water.

Provided herein is an inkjet dye-sublimation ink composition that is formulated to interact with an immobilizing composition such that the ink composition coagulates on the surface of an absorptive substrate, thereby substantially limiting soaking of the ink composition into the substrate. Also provided are a printing process and a printing machine, wherein the ink composition is directly printed on the substrate concomitantly with the immobilizing composition, and thereafter undergo heat-pressing to afford a dye-sublimation transfer of the dye to the substrate, thereby forming an image which is characterized by sharp and well defined edges of the dyed areas.

A method of manufacturing an elastic fabric including a latent crimped yarn according to an embodiment includes forming a raw fabric by knitting the latent crimped yarn and a polyester yarn, reducing the raw fabric, removing oil from the raw fabric, removing wrinkles of the raw fabric, followed by drying, dyeing the raw fabric, and removing wrinkles of the raw fabric, followed by drying to form the elastic fabric. The method can manufacture a highly elastic fabric having excellent recovery and color fastness to washing.

A composition with advantages for textile fibers is disclosed. The composition is a melt of polyester precursors selected from the group consisting of terephthalic acid, dimethyl terephthalate, ethylene glycol, sebacic acid in an amount sufficient to give filaments and fibers made from the melt a dye receptivity similar to cotton at atmospheric pressure; pentaerythritol in an amount sufficient to give pill resistance to yarns blended of cotton with fibers made from the melt, and polyethylene glycol in an amount sufficient to give the melt the elasticity necessary to produce extruded filament from the melt. In an exemplary embodiment, the copolymer melt includes between about 4 and 6 percent sebacic acid, between about 500 and 800 ppm pentaerythritol, and between about 3.5 and 3.9 percent polyethylene glycol, with less than 2 percent DEG, at an intrinsic viscosity of between about 0.640 and 0.690 dl/g, and at a temperature of between about 268° C. and 271° C., with the proportional amounts being based on the amount of polymerized copolymer.
