A dye printing treatment liquid composition to be adhered to a cloth, includes: a polyester resin having a glass transition temperature of 40° C. or more; a cross-linking agent; and water, and the cloth contains fibers which have hydroxy groups.

A fabric processing method of the present disclosure includes an attaching step of attaching a carboxylic anhydride to a fabric containing cellulose, and an esterification step of esterifying a hydroxyl group of the cellulose, in which, in the esterification step, the carboxylic acid is introduced into the cellulose through an ester bond. A molecular weight of the carboxylic anhydride preferably is 1000 or less.

A pretreatment liquid for a fabric used for transfer textile printing, includes a solvent having an organic/inorganic value (I/O value) of 1.0 to 3.0, and has a surface tension of less than 38 mN/m at 25° C.

The present disclosure provides an apparatus for transferring an image onto a textile substrate using dye sublimation, the apparatus comprising: a flat support structure on which the textile substrate is laid with an ink transfer substrate; a heating element that rotates and applies heat while pulling the textile substrate and ink transfer substrate from the flat support structure towards the heating element; and a chevron-shaped brush with the vertex of the chevron pointing away from the heating element wherein the textile substrate and ink transfer substrate pass under the chevron-shaped brush before contacting the heat element. Also provided is a method for transferring an image onto a textile substrate using dye sublimation.

A processing liquid composition of the present disclosure subjected to textile printing and which is used by being attached to a fabric including fibers having a hydroxyl group, includes an oxazoline group-containing polymer and an aromatic carboxylic acid. An oxazoline value of the oxazoline group-containing polymer is preferably 100 or more and 600 or less.

Compositions and methods for treating textile materials so as to facilitate transfer of an image thereto using a dye sublimation transfer system are provided. The compositions are applied to the textile in the form of an aqueous pretreatment composition, which comprises a polymer resin and a crosslinking agent. The resin and crosslinking agent are cured upon the textile material to form an image-receiving area. The sublimation transfer system is then applied to the image-receiving area to form a finished, image-bearing textile product.

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.

A printing treatment liquid composition which is to be adhered to a cloth, includes: a compound including a polyvalent carbodiimide group which has a carbodiimide group equivalent of 500 g/mol or less; and an aromatic carboxylic acid and/or its salt. According to the printing treatment liquid composition described above, a content of the compound including a polyvalent carbodiimide group with respect to a total mass of the treatment liquid composition is 1.0 to 35.0 percent by mass, a content of the aromatic carboxylic acid and/or its salt with respect to the total mass of the treatment liquid composition is 0.1 to 30.0 percent by mass, and the cloth contains fibers having hydroxy groups.

To provide a method of producing a processed cloth capable of forming various concave-convex patterns on a cloth material in a simple manner. A method of producing a processed cloth comprising the steps of: preparing a cloth; printing a first sizing agent containing a foaming agent on at least a portion of the cloth material; and pressing the printed cloth with a heated metal plate to foam the foaming agent. The method of producing a processed cloth may further include a step of printing a second sizing agent containing a coloring agent on the cloth material. The method of producing the processed cloth may further include a step of sublimation transfer to the cloth material.
