摘要:
A dyeing system composition for use in printing articles formed from cellulose prior to dyeing. The dyeing system composition includes the use of both a dye blocking print paste and a dye enhancing print paste to selectively decrease or increase the shade of dyed portions of a cellulose article such as a woven cotton fabric.
摘要:
The present invention relates to a process for the continuous dyeing of cellulose fiber yarns with reactive dyes and to an apparatus for carrying out this process.The process essentially comprises steps of impregnating yarn which has been continuously unwound at high speed from one or several supports (1) and rewound onto one or several supports (3) with at least one fiber-reactive dye in aqueous solution and at least one alkaline reagent in aqueous solution, and fixing the dye.The invention can be applied especially in the technical field of dyeing cellulose fibers.
摘要:
Aminated cellulosic synthetic fibers are produced by adding an amine-substituted cellulose derivative to a viscose or an alkali cellulose and spinning fibers by the viscose spinning process, or by adding said cellulose derivative to a cellulose solution and spinning fibers from said solution.

This invention relates to a polymeric composition for application onto Reemay and Satin acetate fabric for laser printability with a high level (90% or greater readability of printed characters, washability and enzyme rejection/retardation. The polymeric composition is applied by chemical grafting that involves the use of monomers/prepolymers, catalyst, graft initiator and other ingredients of the composition. The coating thus developed and subsequently applied to Reemay and Satin acetate fabric allows to undergo graft polymerization thereby forming a polymeric film which is chemically bonded to the fabric substrate with strong adhesion. The chemically grafted fabric is highly durable and permanent in terms of distinct legibility of the printed characters on the substrate after 55 launderings or 25 dry cleanings and has excellent level or enzyme rejection/retardation when the coated fabric with laser printed characters are subjected to an enzyme wash process.
摘要:
This invention relates to an improved process for dyeing cationic-dyeable polyamide fibers, especially carpet fibers, with an acid dye to provide stain-resistant fibers. The polyamide fibers contain cationically dyeable sulfonate groups along the polymer chain. The improvement involves adding certain water-soluble salts to a dyebath at a concentration of at least 20% based on the weight of fiber.
摘要:
Fiber materials can be modified by applying heterocycloaliphatic compounds containing at least one primary, secondary or tertiary amino group or quaternary ammonium group, the hetero portion of which in the ring is a carbonic ester radical of the formula --O--CO--O-- or a carbamic acid radical of the formula --O--CO--NH--, in aqueous alkaline solution by exposing the fiber material to these compounds at a temperature of between 60.degree. and 230.degree. C. The characteristic of the modified fiber material is that it can be dyed with dye solutions of water-soluble, anionic textile dyes which are low in electrolytes or entirely free of electrolytes and/or are low in alkali or entirely free of alkali. The advantage of a dyeing process carried out in this manner, in particular for fiber-reactive dyes, is that fixation of the dyes under alkaline conditions is unnecessary.
摘要:
A process for the dyeing of fiber materials with water-soluble anionic dyes, in particular those having a fiber-reactive group, is described, according to which dyeing is carried out using low-electrolyte or entirely electrolyte-free and/or low-alkali or entirely alkali-free dye solutions (dye liquors, printing pastes) and in which a fiber material is used which was modified by means of a saturated straight-chain or branched aliphatic or cycloaliphatic compound which is unsubstituted or substituted by one or more hydroxy groups and contains at least one primary, secondary or tertiary amino group or quaternary ammonium group and at least one hydrolyzable ester group, it also being possible for the aliphatic radical in this compound to be interrupted by one or more hetero groups. Modifikation of the fiber material is carried out such that the aliphatic compound mentioned which contains amino and ester groups is applied to the fiber material in aqueous solution and the impregnated material is subjected to a heat treatment. Furthermore, a few new aliphatic compounds containing amino and ester groups are described which can be used for the modification of the fiber material.
摘要:
Modified rayon is produced by adding a modifier to a cellulose solution and spinning fibers from the solution, or by adding a modifier to an alkali cellulose solution or material, xanthating and spinning fibers by the viscose spinning process, wherein the modifier is an amine of the formula (1a), (1b), (1c), (1d) or (1e) ##STR1## The modified rayon produced in this way can be dyed with reactive dyes without addition of electrolyte salt or alkali and have significantly more affinity than conventional viscose fibers.
摘要:
A method, apparatus, and related dye compositions for dyeing textiles which operates at atmospheric pressures, is open to the atmosphere, and does not require the steaming of the textile to set or fix the dye to the textile; specifically, a multi-temperature textile dyeing method which achieves a more complete and even dyeing of the textile in a shorter period of time.
摘要:
A mordant composition for dyeing fibers is provided which comprises a colloidal suspension of aluminum hydroxide in an aqueous medium. The composition is formed by adding an aluminum sulfate salt to sodium or potassium carbonate in aqueous solution at a weight ratio of about 7:1 aluminum sulfate salt to carbonate salt. The preferred aluminum sulfate salt is alum.
