摘要:
Chemical compounds and methods for removing dye from polyester fibers, in particular poly(ethylene terephthalate) (“PET”) fibers, is disclosed. The compounds and methods are particularly useful for removing dye from panel fabric made from recycled PET fibers. The method involves contacting the PET with a dye removal compound in a sealable vessel. The contents of the vessel are agitated and heated to achieve an increase in pressure and temperature. Following a cooling down period, the PET is removed and rinsed with water. The dye removal compound includes an aqueous solution of at least one leveling agent.

An ink-jet printing cloth is disclosed in which a selected type of polyethylene oxide is incorporated in specified amounts. The polyethylene oxide has a larger viscosity average molecular weight of from 100,000 to 3,000,000 and acts to pretreat a starting cloth material so as to be adequate for ink-jet printing. The ink-jet printing cloth,is highly capable of providing images of great color depth with sufficient brightness and sharpness but freedom from an objectionable bleeding. Also disclosed are a textile printing method using that printing cloth and a print resulting from this method.

Aqueous dispersions (D) of a wax (W) dispersed in the aqueous phase by means of a dispersant (B), wherein in (D)the wax (W) is(A) an oxidized hydrocarbon wax or a mixture of oxidized hydrocarbon waxesor a mixture or (A) and at least one non-oxidized hydrocarbon wax (P), the acid number of which is.gtoreq.5,and the dispersant (B) isa non-ionogenic, anionic, cationic or amphoteric surfactant or a mixture of two or more of these surfactants, which displays an HLB.gtoreq.7,and the dispersion (D) optionally contains at least one protective colloid (C), at least one agent (E) for pH-adjustment, at least one antifreeze agent (F) and/or at least one preserving agent (D), but is substantially free of other waxes than (A) and (P) and of other surfactants than (B) and (C),are eminently suitable as wet lubricants that are very stable to temperature modifications and to high electrolyte concentrations, especially as occurring in pretreatment and in dyeing of cellulosic substrates.
摘要:
Cellulosic textile materials can be dyed with disperse dyes from supercritical CO.sub.2 by treating the textile materials with an auxiliary that promotes dye uptake, typically polyethylene glycol.
摘要:
Aqueous processes and compositions of the invention for obtaining a "stone-washed", distressed or "used and abused" look in clothing, particularly in the panels and seams of denim jeans and jackets involve compositions that are stone-free that avoid mechanical abrasion of the fabric. In particular, the process and composition of the invention used to obtain the distressed, "stone-washed" or "acid washed look" are free of common pumice or pumice-bleach compositions, used in large institutional-size laundry machines, and rely solely on the chemical action of aqueous treatment compositions. The aqueous treatments can be made from liquid or solid concentrates.
摘要:
The invention relates to a method of dyeing or printing a textile substrate with disperse dyes, using as a dyeing assistant the product of polyesterifying an aliphatic polyol or etherpolyol or a disaccharide with benzoic acid or substituted benzoic acid.
