摘要:
A roller-lock is used as a sealing system for the inlet and outlet of material webs into or out of autoclaves and consists of a series of individual pressure chambers which are separated or defined by pairs of rollers whereby, the material passing from the atmosphere into the the pressure chamber of the autoclave moves through several staged pressure chambers having increasing pressure therein. When the material passes out of the autoclave it moves through the same chambers in an opposite direction to be subjected to staged decreasing pressure as it passes out of the sealing system.
摘要:
Process for the continuous wet-treatment of textile material under pressure on a sieve-drum device, by leading the textile material in its open-width continuously through a rotating sievedrum device filled with the heated treatment bath and operating under atmospheric excess pressure, while the circulating liquor is pressed through the goods into the sieve-drums.
摘要:
Process for the single-bath dyeing of cellulose fibers and their mixtures with synthetic fibers with water-insoluble azo dyestuffs produced on the fiber according to the exhaustion method, wherein an aqueous dyebath is allowed to act on the textile material, at room temperature or moderately elevated temperature, which liquor contains, in addition to alkaline substances, sodium nitrite and an anionic dispersing system, the solution or dispersion of at least one component capable of entering into azo coupling and at least one non-diazotized primary aromatic amine in a medium on the basis of a water-miscible organic solvent or solubilizer, and after absorption of the coupling component, the diazotization of the amine and the dyestuff formation by coupling is caused in that acid or acid salts are added to the dyeing bath at room temperature.
摘要:
Process for the single-bath dyeing or printing of unmodified polyolefin fibers with water-insoluble pigment dyestuffs by reacting under high-temperature dyeing conditions on these textile materials aqueous liquors or printing pastes containing solutions of pigment dyestuffs reversibly solubilized by cationactive compounds and, optionally, strong alkalis, and substances splitting off acid under heat, or dispersions of the salt-like addition products of dyestuffs having anionic character with cationic compounds, in the presence of a dispersion system on the basis of polyglycol ethers.
摘要:
Process for the single-bath dyeing or printing of unmodified polyolefin fibers with metal-containing phthalocyanine dyestuffs, by reacting under high-temperature dyeing conditions on these textile materials aqueous liquors or printing pastes containing cationically modified phthalocyanine dyestuffs in the presence of a dispersion system on the basis of polyglycol ethers.
摘要:
Process for rinsing or washing and subsequent drying of textile material, in which the material is treated with a bath consisting of or containing a burnable organic solvent, which comprises drying the material by burning off this liquid.
摘要:
Process for dyeing or printing unmodified polyolefin fibers with vat dyestuffs, leuco esters of vat dyestuffs or sulfur dyestuffs, by reacting under high-temperature dyeing conditions on these textile materials aqueous liquids or printing pastes containing the said dyestuffs in unvatted or vatted-up state or as vat acid, in the presence of a dispersion system on the basis of polyglycol ethers and, if required, converting the vatted products applied by reoxidation into their pigment form.
摘要:
Process for the impregnation and subsequent drying of textile material in which the material is treated with an impregnating bath containing an inflammable organic liquid, wherein the materials are dried by burning off of this liquid.
摘要:
Process for preparing dyeings and prints which are fast to light and not capable of being affected by dyeing accelerators (carriers), on synthetic fibrous material, preferably linear polyester fibers, with insoluble dyestuffs, by subjecting the dyeings and prints prepared in the usual manner on textile articles with aqueous preparations of said dyestuffs with the aid of carriers to an aftertreatment in an organic solvent or solvent mixture.
摘要:
Process for the single-bath dyeing or printing of unmodified polyolefin fibers with metal-complex dyestuffs, by reacting under high-temperature dyeing conditions on these textile materials aqueous liquors or printing pastes containing water-soluble or dispersed metallizable dyestuffs and compounds yielding polyvalent heavy-metal ions in the presence of a dispersion system on the basis of polyglycol ethers.
