IMAGE FORMING PRETREATMENT LIQUID, INK SET, AND IMAGE FORMING METHOD
An image forming pretreatment liquid includes a cationic polymer and/or an organic acid of 0.5% by mass or more and 8% by mass or less relative to a total mass of the image forming pretreatment liquid. When the image forming pretreatment liquid includes the organic acid, a lower limit of a content of the organic acid in the pretreatment liquid is preferably 0.7% by mass or more relative to the total mass of the image forming pretreatment liquid. When the image forming pretreatment liquid includes the cationic polymer, a content of the cationic polymer in the pretreatment liquid is preferably 2% by mass or more and 10% by mass or less relative to a total mass of a nonvolatile content of the image forming pretreatment liquid.
Production process of environment-friendly denim fabric and production line thereof
The present invention provides a production process characterized in that a false twisting process is added between a spinning process and a winding process so that yarn slivers undergo excessive pre-torsion in an axial direction and twists which are same in quantity but different in twisting direction are generated on the yarn slivers. Absorption of glucose-containing sulfur dyestuff is performed in a dyeing process. An ammonia removal process is performed in a high-temperature and high-pressure tank so that residual ammonia in a fabric is evaporated. The evaporated ammonia is collected and then fed back to a mercerizing process for continuous use. The present invention also provides a production line including a spinning unit having a false twisting device, a dyeing unit configured to realize the dyeing process, and a liquid ammonia finishing unit consisting of a fabric mercerizing device, an ammonia removal device, an ammonia recycling device and a controller.
Formulations having benzoate dye carriers for meta-aramid articles
Glycol ether benzoates, glycol benzoates and methyl benzoate facilitate the dyeing of the meta-aramid article, e.g., fibers, at or near neutral pH. The addition of an anionic surfactant, such as sodium lauryl sulfate, enhances the performance of the benzoates.
Reversible color-changing sanitizer-indicating nonwoven wipe
A nonwoven wipe having a reversible sanitizer indicator for multiple uses and recharges is provided. The nonwoven wipe includes a cloth-like nonwoven fabric coated with a reversible color-changing ink formulation. During use, the nonwoven wipe is impregnated with a quaternary ammonium compound-based sanitizer. When the level of free quaternary ammonium compound falls below a threshold level, the color-changing ink formulation changes from a first color to a second color, indicating the need to recharge the wipe. When the nonwoven wipe is recharged with sanitizer solution, the color-changing ink formulation changes back to the first color.
DYE DISCHARGE INKJET INK COMPOSITIONS
A dye discharge composition exhibiting extended shelf life and/or pot life and high suitability for inkjet printing on dyed substrates, is disclosed. The composition comprises a reducing agent such as, for example, a sulfur-based reducing agent, and a chelating agent, such as a sodium salt of a polyamino carboxylic acid chelating agent. Use of the dye discharge composition in combination with a translucent colored composition and an optional opaque underbase composition, for forming an image on a dyed substrate is also disclosed. Processes for inkjet printing of an image on a dyed surface using the dye discharge composition, kits for use in such processes or an ink formulation containing same are also disclosed.
INK SET
An ink set contains a pretreatment solution and an ink composition, wherein the pretreatment solution contains an organic acid with a boiling point of 120 C. or lower at 1 atmospheric pressure, and the ink composition contains A to E below: (A) a white pigment; (B) an alkali-soluble resin being an acrylic-based copolymer resin with an acid value of 200 mgKOH/g or higher that also contains a monomer having carboxyl groups and a hydrophobic group-containing monomer as monomer components, amounting to a content of 1.0 to 3.0% by mass in the ink composition; (C) a water-dispersible resin with a glass transition temperature of 25 C. to 10 C.; (D) a silicone-based surfactant; (E) water. The ink set that can provide a printed matter (fabric) offering excellent abrasion resistance of the printed text and images, as well as good washing fastness and tackiness (non-sticking) of the printed face.
Method for producing denim-effect garments
A method is disclosed for producing denim-effect garments by the following steps: 1) printing a reactive dye ink onto a PET film to form a pattern thereby obtaining a transfer printed PET film; 2) transfer printing a base pulp-treated fabric by attaching the transfer printed PET film thereby obtaining a denim-effect fabric; 3) cutting, sewing, washing to soften, and drying the denim-effect fabric and thereby obtaining a denim-effect garment. The method has the advantages of simple production, being environmentally friendly, having high efficiency, and being suitable for flexible fabrics, and the produced denim-effect garment of the invention has the advantages of having a good color fastness to rubbing, washing resistance, and having a diversity of patterns, and are suitable for large-scale production and application.
