Abstract
A process for dyeing textile fibers employs a colorant medium comprising a disperse dye and an aqueous dispersion of a copolymer selected from vinyl ester-based copolymers, alkyl acrylate copolymers, alkyl methacrylate copolymers and mixtures thereof. The textile fibers are passed through at least one dye bath containing the colorant medium to deposit the colorant medium at least on the surface of the fibers. The fibers with the colorant medium deposited thereon are then passed between padding rollers to distribute the colorant medium through the fibers, whereafter the fibers are heated to cure the copolymer and bond the disperse dye to the fibers.
Description
Invention field
The present invention relates to and by DISPERSE DYES, textile fiber is dyeed, particularly cellulose fiber peacekeeping particularly cotton fiber.
Background of invention
The cotton fiber of yarn and form of fabric normally dyes with chemically-reactive dyes, direct dyes, sulphur dyestuff, cylinder dyestuff, indigo dye or mordant.The industrial reactive coloration being preferred for clothes is the cotton that whole dyestuffs provides most light yellow look as chemically-reactive dyes at present.Water-soluble reaction dyestuff (also it provides and have the good coloration result washing fastening properties) may be used for dyeing or printing hydrophilic cellulose fiber such as cotton fiber.In such flow process, cellulose fibre-OH group (it can obtain on this fiber surface) reacts with the fiber-reactive groups of chemically-reactive dyes, defines covalency fiber/dyestuff and combines.
Directly (direct/substantive) dyestuff is used in neutrality when adding sodium chloride or sodium sulphate or light subalkaline dye bath.Cylinder dyestuff is such as indigo-blue substantially water insoluble.Reduction in akaline liquid creates the water-soluble alkali metal salts of cylinder dyestuff, and this salt has for the such as cotton affinity of textile fiber.Both direct dyes and cylinder dyestuff provide dark tone, which limit they expand to whole cotton dyeing application in ability.
Good COLOR FASTNESS is created with chemically-reactive dyes dyed cotton.But chemically-reactive dyes is strongly hydrophilic, which results in dye loss and low process efficiency and high cost, therefore this allow the reactive responsive needs for high pH and hot conditions owing to needing to use long dyeing time and the interpolation of salt and alkali.Final and the water of chemically-reactive dyes (it does not react with gossypin in staining procedure) reacts and is hydrolyzed.The dyestuff of this hydrolysis, after dyeing with rear soaping steps, from the removing of cotton surface, must improve crock fastness (crockfastness) and washes fastening properties.Chemically-reactive dyes is also under sifting at present, because it may be carcinogen.
Another kind of dyes being generally used for colored textiles comprises DISPERSE DYES.DISPERSE DYES is developed at first and is used for cellulose acetate is dyeed, and is water-insoluble.DISPERSE DYES is fine ground in the presence of dispersants.DISPERSE DYES is mainly used in making polyester dyeing, but they also may be used for making dyeing nylon, cellulose acetate and acrylic fiber.Need the temperature of 130 DEG C with disperse dyeing polyester, it is that exhaust (in batches) machine (such as spraying machine) by there being high pressure or the continuation method (see Thermasol method) with stent frame provide.
Given their lack cellulosic affinity or substantivity, DISPERSE DYES can not easily for making cotton fiber and textile dyeing.But, carried out the flow process that some attempt the cotton fiber such as fabric provided with disperse dyeing modification.Such as U.S. Patent Publication No.2006/0048308 discloses and a kind ofly uses DISPERSE DYES to dye or print the method containing cellulosic fibrous material.Such method comprises with the water-soluble or dispersible mylar of water and water-soluble or water dispersible acrylic adhesives pretreatment of fiber cellulose fiber material.This mylar is fixed in such as COTTON FABRIC via preliminary treatment body lotion with acrylic adhesives and strong cross-linking agent (such as melamine).Then the fabric of this polyester dipping dyes under the pressure condition of the temperature of 130 DEG C and raising by the moisture dye bath containing DISPERSE DYES.But high-caliber resin binder required in this method creates adverse influence for the compliance of DYED FABRICS.
In addition, International Patent Publication No.WO2012/135622 discloses a kind of method made containing the dyeing of cotton textile fiber, and first this fiber uses the process of cellulose reactive emulsion copolymers wherein, provides the combination of emulsion copolymers and fiber.Then the combination of this emulsion copolymers and fiber solidifies via the cellulose reactive monomer in this copolymer and the cellulose hydroxyl group partial reaction in cotton fiber, this emulsion copolymers chemistry is fixed on cotton fiber, forms the cotton fiber of copolymer process thus.Then the cotton fiber of this copolymer process contacts with disperse dye stuffs in such a situa-tion, and this condition is enough on the copolymer component of cotton fiber disperse dye stuffs being attached to this copolymer process.
But, although ' method disclosed in 522 creates has excellent crock fastness, light fastness and wash fastness, and do not weaken the COTTON FABRIC of the dyeing of the compliance of fabric, but be desirable to and a kind of monobath solution method for dispersion dyeing COTTON FABRIC is provided, particularly use continuous pad dyeing method.
