Abstract:
A non-woven fabric with melange-type visual appearance and endowed with high-durability comprising a fiber part and a matrix binder characterized by the binder matrix being a polyurethane characterized by the presence of soft segments and rigid segments, the former constituted from mixtures of polycarbonate-polyols and polyester-polyols, and the latter, from urethane groups deriving from the reaction of isocyanates with ureic polyols, and groups deriving from the reaction between the free isocyanate groups and water, and the fiber part comprises a fiber of melange appearance that is a mixture of two or more fibers with different dyeability characteristics.

Abstract:
A dyeing assistat containing at least(a) an alkylbenzene or tetrahydronaphthalene (tetralin) or a mixture thereof,(b) an anionic surfactant,(c) a non-aromatic and water-immiscible solvent and optionally also(d) a polar solvent and/or(e) a non-ionic surfactant; this dyeing assistant can be used to promote the migration of the dyes and thus to improve the levelness and dye yield when dyeing synthetic fibre material, preferably polyester, in particular in the temperature range from 80.degree. to 130.degree. C.
Abstract:
Process for the coloration of polyester or cellulose-triacetate textile materials, or polyester/cellulose unions, with disperse anthraquinone dyestuffs containing an alkoxycarbonylalkoxy group and giving a subsequent alkaline rinse.
Abstract:
Process for the exhaust dyeing of wound bodies of synthetic or natural fiber materials with appropriate dyestuffs, by heating the wound-up textile articles to temperatures ranging at or above 100.degree. C while replacing the air in the dyeing vessel by saturated or superheated steam, and by preparing the dye bath in the batch vessel which is connected by pipes with the dyeing vessel, and heating up the dyebath to temperatures also ranging at or above 100.degree. C. A special control of the temperature and of the steam pressure in both closed systems is provided to secure the formation of a relative excess pressure of 2.94 to 9.8 bars in the batch vessel or such an excess pressure is produced from the outside. The hot dyebath is pressed by the differential pressure over a period of 3 to 60 seconds at the same time from inside and outside into the dry or wet wound bodies.
Abstract:
Polyester fibers and cellulose fibers, and blends of these fibers, are dyed continuously with disperse dyes, or dispersed dyes, by continuous application of an aqueous dye liquor which contains, as the essential dyeing assistant, a polyoxyalkylated amine, a polyoxyalkylated amine-oxide and/or a quaternized polyoxyalkylated amine which in 1% strength aqueous solution has a cloud point of not less than 18.degree. C and which is derived from amines which contain at least 2 nitrogen atoms and at least one group which can be oxyalkylated, followed by drying and fixing.
Abstract:
AN IMPROVEMENT IN THE PROCESS OF DYEING POLYESTER MATERIALS BY PADDING IS OBTAINED BY USING PADDING LIQUORS CONTAINING AN AUXILIARY COMPRISING
(A) POLYACRYLIC ACID ALKYLENE GLYCOL ESTER, E.G. HYDROXYETHYL ESTER OF POLYACRYLIC ACID; AND (B) ALKOXYLATION PRODUCTS OF MANNICH COMPOUNDS PRODUCED FROM PHENOLS, FORMALDEHYDE AND AMINES (B1) OR 1-2 -SO3M-GROUP CONTAINING ALKOXYLATION PRODUCTS OF FATTY AMINES (B2) WHEREIN M IS HYDROGEN, AMMONIUM ALKALI METAL OR ALKALINE EARTH METAL.
Abstract:
A soil-releasing, stain-concealing apparel made from a fabric comprising natural and synthetic materials, or blends thereof. The fabric is cross-dyed with two colors, at least one of which is a stain-conforming color. The fabric is also treated with a soil release agent.
Abstract:
The present invention provides a method of applying ink containing dyes to fabric composed of synthetic and cellulose fibers using an ink-jet system to print the fabric with high color shade depth and brilliancy and ink-jet printed goods obtained by the ink-jet printing method. The fabric composed of cellulose and synthetic fibers is treated with an acidic aqueous dispersion containing cellulose reactive compound, water-soluble polymer and non-water-soluble inactive organic compound with a melting point of 40° C.-150° C. and the fabric is dried before its ink-jet printing with reactive and disperse dyes.
Abstract:
Process for dyeing and printing blended fabrics made from polyester and natural fibre materials, characterized in that the dye baths, padding liquors or printing pastes contain compounds of general formula (I). Dye preparations containing one or more compounds of general formula (I).
