Disclosed herein is a method for dyeing and removing colored impurities, which includes providing a polyester fabric and an adsorption material, spraying a coloring material onto a surface of the polyester fabric to form a colored layer, subjecting the polyester fabric thus dyed to a heating treatment for the colored layer to adhere to the surface of the polyester fabric, attaching or applying the adsorption material onto the colored layer and subsequently heating and/or applying a pressure to the adsorption material so that the adsorption material is coated on the colored layer to adsorb colored impurities therefrom, and removing the adsorption material.

[Problems] Provided is a discoloring body which is discolored by application of water and has high glossiness and is excellent in applicability to various fields such as a toy field, a decoration field, and a design field.

[Solution] A discoloring body including a supporting body, a porous layer in which a low refractive index pigment is fixed in a dispersed state by way of a binder resin, and a glossy resin layer, in which an occupancy area ratio of the glossy resin layer is 1% to 95% with respect to a 1 cm square at any position in the porous layer.

A whitening composition for fabric, in particular, unbleached cellulosic fiber-containing fabric. The composition includes a blue dye, a violet dye; and, optionally, a thickening agent; wherein the composition is free of bleaching agents and optical brighteners. A method of whitening a fabric using whitening compositions is also disclosed.

A non-aqueous fabric dyeing method used a non-aqueous dyeing composition. The dyeing composition is a fluid at room temperature; contains no more than 5% water, no more than 5% VOCs and no more than 2.5% by weight vinyl monomers. The dye composition includes an organic dye that is solid at temperatures up to 130° C. and which sublimes or boils at 130 to 220° C., and further includes a carrier that is a liquid in the temperature range of 130 to 220° C.

The present invention relates to the field of denim fabric processing, specifically to an environmentally-friendly processing method for dyeing denim fabric with zero discharge. The method includes: step 1, a treatment of white warp yarns; step 2, a primary drying operation; step 3, a coating spray-dyeing operation; step 4, a secondary drying operation; step 5, a sizing operation; step 6, a ternary drying operation; and step 7, a doffing operation. In the present application, as warp yarns are dyed using the coating spray-dyeing technology, highly corrosive auxiliaries such as sodium hydrosulfite and sodium sulfide are not needed in the dyeing process, and the dyed warp yarns are not required to be treated in a washing tank, so that zero effluent discharge is achieved.

Composite particles contained in an ink are particles of a composite of a polyester resin including a sulfonic acid group and a basic dye. The polyester resin has a glass transition point of 40 C. to 70 C. The polyester resin includes a first repeating unit derived from a polyvalent carboxylic acid having the sulfonic acid group, a second repeating unit derived from a polyvalent carboxylic acid having no sulfonic acid group, and a third repeating unit derived from a polyhydric alcohol. The content ratio of the first repeating unit relative to the total amount of the first repeating unit and the second repeating unit is at least 1.5 mol % and no greater than 20.0 mol %. The mass ratio of the polyester resin to the basic dye is at least 1.0 and no greater than 10.0.

A fluid set for textile printing includes an aqueous inkjet ink containing a pigment stabilized by anionic dispersing groups and an aqueous pre-treatment liquid. The aqueous pre-treatment liquid includes a capsule having a core including a thermally reactive crosslinker and a polymeric shell stabilized by cationic dispersing groups.

An adhesive layer carrying a uniform color or a color-scheme is placed within or under a colored or color-printed conformable fabric that is simultaneously or subsequently molded into a three-dimensional shape or embossed with a three-dimensional pattern. The thermoplastic adhesive layer proceeds towards the fabric surface and matches or masks the color gaps opened on the surface by molding or embossing. The fabric can also be laminated to a backing during the molding or embossing process.

A new method of delivering more precise amounts of carpet mill dye to regions of discoloration using a roller-ball applicator enables precisely metered delivery of the three primary dye colors to discolored carpet fibers. The method eliminates the need for a water extraction, enables the restoration of a more uniform color pattern, and eliminates dye overspray outside of the treated region that is inherent with the use of a spray bottle. The applicator is held with a loose grip and the roller ball is alternately moved in clockwise and counter-clockwise directions while in contact with the carpet fibers to be dyed. This ensures that dye is delivered to all sides of the fiber. To ensure even dye penetration and improved motion of the roller ball, an emulsifier is added to the dye solution. After each application, a microfilament cloth is wiped across the treated region.
