A dyeing method in which a transparent resin body having a surface applied with a dye is heated to fix the dye to the transparent resin body comprises a heating step of irradiating a laser beam having a wavelength less likely to be absorbed by the dye toward the transparent resin body applied with the dye on the surface while relatively scanning the laser beam with respect to the transparent resin body to heat a to-be-dyed region of the transparent resin body to fix the dye, wherein the laser beam is irradiation to heat by changing a laser beam irradiating condition with respect to a portion of the transparent resin body to be heated so that a heating temperature on the transparent resin body by irradiation of the laser beam is substantially equal throughout an entire area of the to-be-dyed region.

A dye printing treatment liquid composition is used to be adhered to a cloth and includes a polyester resin and water, the polyester resin includes a structural unit derived from an aromatic compound and a structural unit derived from a non-aromatic compound, the aromatic compound includes a phthalic acid, the non-aromatic compound includes a (poly)alkylene glycol, a content of a structural unit derived from the phthalic acid with respect to 100 percent by mole of the polyester resin is 15 to 85 percent by mole, and a content of a structural unit derived from the (poly)alkylene glycol with respect to 100 percent by mole of the polyester resin is 15 to 85 percent by mole.

The present invention is a process of producing a decorated case insert suitable for use on a phone or tablet that applies a synthetic organic polymer coating onto a heat stabilized extruded polymeric substrate, and diffuses a set of disperse dyes in the form of an image into the polymer applied coating through the application of heat and pressure. The decorated insert is then cut to match an article or manufacture, such as a phone or tablet case, and affixed onto that case to form a decorated case.

A transfer sheet is provided, whereby a T-shirt or the like can be printed in few steps by means of an electronic image forming device that uses powdered toner, liquid ink, or the like containing a plastic resin. By means of mirror-image printing a picture pattern, which is an electronic image, onto a first sheet, aligning the first sheet and a second sheet, and heat-pressing, a coating is spread over a portion of the picture pattern printed onto the first sheet. The first sheet has a structure including a mold release layer, a resin layer, and a porous resin layer in a substrate, and the second sheet includes a mold release layer, a resin layer, an adhesive layer, and a colored porous resin layer in a substrate.

A printing method of the present disclosure includes a pre-treatment liquid adhesion step of adhering a pre-treatment liquid to a cloth and a thermal transfer step in which while a transfer medium on which an image is formed by a sublimation transfer ink jet ink containing a disperse dye and water is faced to the cloth to which the pre-treatment liquid is adhered, the image is thermal-transferred to the cloth. In the printing method described above, the pre-treatment liquid contains a polyester resin, a cross-linking agent, and water, and in the pre-treatment liquid adhesion step, the pre-treatment liquid is adhered to the cloth so that a product of a water absorbability [s] of the cloth obtained by the sedimentation method in accordance with JIS L 1907: 2010 7.1.3 and an adhesion amount [g/m.sup.2] of the polyester resin to the cloth is 8.0 to 16.0 [s.Math.g/m.sup.2].

The disclosure relates to a fabric for lightweight nautical sails, such as spinnakers, asymmetric spinnakers, and gennakers, for sailboats and other surface vessels, the fabric being formed of continuous polyester warp and weft yarns and being coated on one or both of its two surfaces with a crosslinked polymer, wherein the polyester is poly(ethylene terephthalate) (PET) having a tenacity greater than or equal to 6 cN/dtex; in that the fabric has a density of between 20 and 50 threads/cm. The coated fabric has an elongation in the bias direction under 20 Lbs, comprised between 10 and 30 hundredths of an inch.

A fabric for a ship traction structure is provided that is formed from multifilament continuous warp yarns and weft yarns and coated on one or both of its two surfaces with a polyurethane (PU), the fabric having a coverage rate TC of between 1.8 and 4, the yarns being made of poly(ethylene terephthalate) (PET) and a density of between 20 and 50 yarns/cm, in terms of warp and weft density, the polyurethane (PU) being crosslinked and polyether-, polyester-, or polycarbonate-based. The crosslinked PU is derived from crosslinking a single-component polyurethane having a modulus at 100% elongation less than or equal to 5 MPa according to standard DIN 53504, implemented in organic solvent phase and a crosslinking agent. A ship traction structure of the paraglider sail type made with such a fabric is also provided.

A pretreatment liquid for textile printing according to the embodiment of the present disclosure includes a polyester resin (A) obtained by subjecting an alcohol component and a carboxylic acid component to polycondensation, a crosslinking agent, and water, in which the carboxylic acid component contains phthalic acid, an acid value of the polyester resin (A) is 5 to 40 mgKOH/g, an aromatic ring concentration of the polyester resin (A) is 4.20 to 5.20 mol/kg, and a glass transition temperature of the polyester resin (A) is 0 C. to 40 C.
