TEXTILE MATERIALS ON THE BASE OF SYNTHETIC OR NATURAL POLYAMIDE FIBERS ARE DYED OR PRINTED WITH WATER-SOLUBLE WOOL-DYESTUFFS IN THE PRESENCE OF (A) AN AMINOPLAST PRECONDENSATE AND AN ACID CURING CATALYST, (B) UREA, THIOUREA OR GUANIDINE, (C) A HYDROXYALKYLECELLULOSE AND (D) AN ALBUMINOUS SUBSTANCE. AFTER DYEING OR PRINTING THE MATERISLS ARE STREAMED WITHOUT INTERMEDIATE DYING. THIS PROCESS PROVES PARTICULARLY ADVANTAGEOUS IN PRINTING OR PADDING THICK OR STIFF MATERIALS SUCH AS FLEECES, FELTS OR CARPET WEBS.
摘要:
A dyeing and welding process may be configured to convert a substrate into a welded substrate having at least some color imparted thereto via a dye and/or coloring agent by applying a process solvent having a dye and/or coloring agent therein to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may include a binder, such as dissolved biopolymer (e.g., cellulose). After application of a process solvent comprised of a dye and/or coloring agent, the substrate may be exposed to a second application of a process solvent comprised of a binder, which second application may occur before or after a process temperature/pressure zone, process solvent recovery zone, and/or drying zone.
摘要:
The present invention provides a process for the production of a fabric having a unique appearance and the fabric so obtained. Also provided is the clothing articles, i.e. garments, including the fabric. More particularly, the present invention relates to a process for producing a woven fabric having a unique, e.g. “used” (i.e. worn-out) or “multi-shaded” appearance and the process includes a step of providing a woven fabric with a layer of bacterial biopolymer, dyeing at least part of the fabric together with the biopolymer layer, and then removing at least part of the bacterial biopolymer layer from the fabric.

An ink jet textile printing penetrant includes a water-soluble organic solvent; a surfactant; and one type or two or more types selected from the group consisting of a chelating agent and an aromatic compound.
摘要:
Disclosed are various embodiments for dyeing a material using a dyed nanocellulose dispersion, thereby reducing or eliminating the need for water in dyeing materials, such as fabrics and textiles. A dyed nanocellulose dispersion or gel may be prepared from wood pulp fibers using a homogenizer and a dye, wherein the dyed nanocellulose dispersion comprises nanosized cellulose fibrils. The dyed nanocellulose gel may comprise an approximate concentration of 0.5% to 6%. The dyed nanocellulose dispersion may be applied to a material, such as a fabric or textile material. The fabric or textile material can be dried resulting in a dyed material.
摘要:
A pretreatment agent for ink jet printing employing an acid dye includes hydroxyethyl cellulose; ammonium salt; a hydrotropic agent; and water, wherein the content of the hydroxyethyl cellulose is in the range of 1 to 5 wt % and the content of ammonium salt is in the range of 1 to 6 wt %.
