摘要:
The present invention relates to a method for dyeing wood veneer. The veneer is immersed in a dye bath. The dye is preferably heated to speed up penetration times. The dye bath containing the veneer is then put into pressurized chamber and pressurized to 50-500 psi. The chamber is pressurized until the wood absorbs the amount of color that is desired. When the color is absorbed the pressure is released and the veneer is removed. The veneer is then washed with water until there is no bleeding and then air dried.
摘要:
A disperse dye mixture which comprises, on a weight basis, from 5% to 70% of the dye of Formula (1), from 5% to 70% of the dye of Formula (2), and from 0% to 40% of the dye of Formula (3), wherein each of R and R.sup.1 represents an alkylene group and each of R.sup.2 and R.sup.3 represents an alkyl group.
摘要:
A high heat-resistant synthetic fiber material containing, for example, aramid, PEEK, or PEN fibers, that can be dyed uniformly at a high color density, with a dye dissolved or dispersed in a liquid medium, for example, water, and having a molecular weight of 330 to 400, at a dyeing temperature of 150.degree. C. or more within a closed system.
摘要:
A process is disclosed for the pad-dyeing or printing of web-like textiles consisting totally or partially of cellulose fibers, with aqueous padding liquors or printing pastes containing one or several reactive dyes and optionally, thickening and padding auxiliaries, the starting pH values of the liquors and pastes being in the slightly acid range, which comprises fixing the padded or printed dyestuffs, without the addition of alkalis or alkali-yielding agents, by subjecting the dyestuffs to high-pressure steam or high temperature steam or dry heat.
摘要:
The surfactants of this invention are phenolic-formaldehyde resins that have been sulfomethylated with from 1-13 moles of sulfomethylation per 1000 grams of the starting resin and further modified by reaction with up to 20 moles, preferably 0.25 to 10 moles, per 1000 grams of starting resin of a blocking agent of the type X(CHR).sub.m (CH.sub.2).sub.n Y, wherein X is a halogen, an activated double bond, epoxy ring or halohydrin, Y is a property group such as sulfonate, phosphonate, carboxylate or hydroxyl, R is another property group such as hydrogen, hydroxyl, mercaptan or amine, and n and m are integers from 0 to 5, with n or m being at least 1, to at least partially block the phenolic hydroxyl group of the resin. The phenolic-formaldehyde resin may also be cross-linked to tailor its molecular weight and then treated with urea or ammonia, if desired.
摘要:
POLYESTER FABRIC IS DYED WITH AZO DYES MADE BY COUPLING AN APPROPRIATE DIAZOTIZED AMINOBENZENE INTO AN A-(NALKYLANILINO)-M-TOLUENE-SULFONAMIDE, TYPIFIED BY A-(NETHYLANILINO)-M-TOLUENE-SULFONAMIDE. THIS CLASS OF AZO DYES, WHEN APPROPRIATELY DISPERSED, PRODUCES DYEINGS ON AROMATIC POLYESTER FABRICS WITH EXCELLENT SUBSTANTIVITY, OUTSTANDING SUBLIMATION FASTNESS, AND GOOD FASTNESS TO LIGHT. THE DYES ARE APPLIED TO POLYESTERS, SUCH AS POLYETHYLENE TEREPTHALATE, BY CARRIER DYEING, PRESSURE DYEING AND THERMOFIXATION METHODS.
