Abstract
A process for producing an evenly-dyed fabric comprising both cotton fibres and man-made cellulose fibres, in which a fabric is manufactured from both said fibres and is dyed, is characterised by impregnating the man-made cellulose fibres, prior to manufacture of the fabric, with a water-soluble, flexible linear polymer and a cross-linking agent reactive with cellulose, and, at a stage of the process prior to dyeing of the fabric, effecting a cross-linking reaction between the man-made cellulose fibres and the cross-linking agent, thereby producing a reduction in the dye affinity of the man-made cellulose fibres to a level more proximate to the dye affinity of the cotton fibres.
Description
Technical field
The present invention relates to a kind of method that comprises that crosslinked man-made cellulose fibers and the fabric that subsequently this fiber is made dye.
Man-made cellulose fibers is by obtaining naturally occurring cellulose source (as wood pulp), is translated into spinnable solution and spins fiber and make from this solution.Lyocell fibers (lyocell fibre) is to adopt a kind of usually said solvent spinning method that cellulose solution is expressed into the man-made cellulose fibers that makes in the coagulating bath by spinning head.This method is described in US-A-4, and 246,221, water-based tertiary amine N-oxide (specifically being N-methylmorpholine N-oxide) is as solvent.The lyocell fiber is different from other man-made cellulose fibers, and the latter's method for making is that cellulose is formed the soluble chemical derivative, this derivative solution is expressed in the bath so that this extrudate is regenerated as cellulose fibre then.Viscose comprises high strength modal types, forms soluble derivative by this method and makes.
Background technology
Known, cellulosic fabric is carried out crosslinking Treatment can give this wrinkle resistance in fabrics, durable press or washability.The general introduction of this processing is found in Kirk-Othmer ' s Encyclopaedia of ChemicalTechnology (Kirk-Othmer chemical technology encyclopaedia), the third edition, volume 22 (1983), Wiley-Interscience, the article that is entitled as " Textiles (Finishing) ", the 769-790 page or leaf, and H.Petersen is at Rev.Prog.Coloration, Vol 17 (1987), the description of 7-22 page or leaf.Crosslinking agent also can be known as other title sometimes, for example crosslinked resin, chemical finishing agent and resin finishing agent.Crosslinking agent is to contain a plurality of micromolecule that can form crosslinked functional group with hydroxyl reaction in the cellulose.One class crosslinking agent comprises the N-hydroxymethyl resin, promptly contains the micromolecule of two or more N-methylols or N-alkoxy methyl (particularly N-methoxy).The N-hydroxymethyl resin is used in combination with the acid catalyst of selecting for use for the improvement cross-linking properties usually.In a kind of typical method, the solution that will contain have an appointment 5-9 weight %N-hydroxymethyl resin crosslinking agent and 0.4-3.5 weight % acid catalyst pads (pad) on the cellulose fibre of drying, obtain 60-100 weight % wet pickup, then will wetting fabric drying, also set crosslinking agent is heating and curing.
Known, the anti-crease finishing processing can make cellulose fiber peacekeeping fabric become fragile, thereby causes the loss of ABRASION RESISTANCE, TENSILE STRENGTH and tearing strength.Must be between the reduction of the raising of wrinkle resistance and other mechanical performance seeking balance.
Also known, above-mentioned crosslinking Treatment can reduce the dye affinity (dye affinity) of cellulosic fabric.This be considered to one very serious so that may get rid of the shortcoming of using such processing, especially work as below about 50-60% of dye affinity that dye affinity is reduced to suitable non-crosslinked cellulose fibre.The someone attempts combining the reduction that limits dye affinity by adding linear polymer with cellulose by crosslinking agent.These attempt having obtained success to a certain degree.
For example, US-A-4,780,102 described a kind of COTTON FABRIC is carried out crosslinked to give the method for its washability: with N-methylol crosslinking agent, the acid catalyst that is used for cross-linking reaction and polyethylene glycol fabric is padded.Dry this fabric, and heating is crosslinked to carry out before dyeing.The adding of polyethylene glycol makes can carry out poststaining (post-dye) by enough used dyestuffs of dyeing cellulosic commonly used through crosslinked fabric, obtains the required washability that crosslinking Treatment is given simultaneously.The dye level that this method obtained still is lower than noncrosslinking COTTON FABRIC.An advantage like this is: by using cross-linking chemistry reagent as printable formulation, to obtain the differential dyeing between its printing zone and the non-printing zone when the fabric poststaining.
US-A-5,580,356 have described the another kind of method that balance obtains crosslinked benefit and keeps dye affinity that is intended to, and in the method, carry out crosslinked to reduce the fibrillation trend of lyocell fiber.A kind of linear polymer (as polyethylene glycol) of flexibility is added crosslinking agent to give crosslinked lyocell fiber with dyeing affinity in the poststaining operation.
Other colouring method of the fabric of cellulose is described in US-A-4, in 629,470 and US-A-5,298,584.
The invention still further relates to the cross-linking method that uses a kind of the above-mentioned type, but purpose is to overcome the cotton problem of comparing the dye uptake reduction with man-made cellulose fibers (as lyocell fiber and viscose) and causing.
Summary of the invention
The invention provides a kind of method of making the fabric that contains cotton fiber and man-made cellulose fibers of level dyeing, wherein fabric is made and is colored by described two kinds of fibers, it is characterized in that, before making fabric, flood described man-made cellulose fibers with water-soluble flexible linear and the crosslinking agent that has with cellulose reactive, and, stage before the DYED FABRICS in the method, carry out the cross-linking reaction between man-made cellulose fibers and the crosslinking agent, thus the dye affinity of man-made cellulose fibers is reduced to more level near the dye affinity of cotton fiber.
This method makes it possible to fabric is evenly caught monochrome, by comparison, can obtain the effect of stigma fault, folder look or dye speck when the fabric that makes when these fibre blends under the regular situation is colored.
The dye affinity of fiber is a relative value, and it is by the test determination of the fabric sample through weighing of use standardization dye bath and method dyeing.The intensity of colour spectrophotometer measurement of gained and dyes to the Comparative Examples fabric of identical formation and weight with same procedure and measures resulting value and compare.The value that Comparative Examples provides is typically expressed as 100%, and compare with the Comparative Examples ratio of the intensity of colour that the value representation that provides records for both of fabric multiply by 100%.Will in specification, illustrate after a while and be fit to the dye affinity test that the inventive method is used to measure the dye affinity of fiber.
Obtaining monochromatic required color homogeneity is judged by range estimation usually.Desired uniformity standard can change according to the expection final use of DYED FABRICS, and can change according to used dye colour.Under latter event, for example, weld is than the easier burl dyeing of covering up of navy blue dyestuff.Consider these conditions, we find, if the dye affinity of man-made cellulose fibers is reduced to cotton fiber dye affinity (is 100% in the cotton fiber dye affinity) and differs in about 15% scope (in ± 15% scope, but more generally be+15%), use method of the present invention can realize evenly catching monochrome usually so.
The dye affinity of cotton fiber changes according to its type, source and processing method, but with the dye affinity of cotton fiber during as 100% reduced value, the dye affinity of generally held standard viscose is about 130%, and the dye affinity of standard lyocell fiber is about 140%.Although the original dye affinity difference between man-made cellulose fibers and the cotton fiber can obtain the mixed goods of level dyeing with the inventive method.
Man-made cellulose fibers is the lyocell fiber preferably, but other man-made cellulose fibers of the inventive method use such as viscose also is effective.
Can on the fiber of fibers form or yarn form, carry out with cross-linking chemistry reagent-impregnated man-made cellulose fibers.Preferably before the fiber spun yarn, carry out, be more preferably, when man-made cellulose fibers is still during undried bundle form, promptly fiber has just carried out after the wet spinning but before first time drying, flexible linear and crosslinking agent has been used thereon with the solution form.
Crosslinking agent can be any crosslinking agent that is used for the cellulose anti-crease finishing as known in the art usually, but preferably is classified as the crosslinking agent of formaldehydeless or low formaldehyde, is used in combination with a kind of crosslinking catalyst and is advisable.When carrying out the inventive method on fabric, this crosslinking agent is formaldehyde-less crosslinker preferably.
The low formaldehyde crosslinking agent of one class comprises the N-hydroxymethyl resin.The example of suitable N-hydroxymethyl resin is the material that above-mentioned Petersen illustrates in the article described in the Kirk-Othmer.The example of these resins comprises 1,3-dimethylol ethylene urea (DMeEU), 1,3-dimethylol propylidene urea (DMePU) and 4,5-dihydroxy-1,3-dimethylol ethylene urea (DHDMeEU).Other example comprises the compound based on urones, triazinone (triazinones) and carbamate.Another example of suitable crosslinking agent is a melamine.
In the formaldehyde-less crosslinker, a preferred class comprises based on 1,3-dialkyl group-4, and 5-dihydroxy (alkoxyl) ethylidene-urea, as 1,3-dimethyl-4, the compound of 5-dihydroxy ethylidene-urea (DMDHEU).Another example of suitable formaldehyde-less crosslinker is ethylene-dimalonic acid (BTCA).The crosslinking agent that will be used for the cellulose anti-crease finishing usually is used in combination with the catalyst that is used for cross-linking reaction (normally acid catalyst).Method of the present invention is preferably used such catalyst: it is recommended uses with selected crosslinking agent.For example, N-hydroxymethyl resin and 1,3-dialkyl group-4,5-dihydroxy (alkoxyl) ethylidene-urea preferably is used in combination with a kind of acid catalyst, acid catalyst for example is organic acid such as acetate, and perhaps potential acid such as ammonium salt, amine salt or slaine are as zinc nitrate or magnesium chloride.Also can use the catalyst system of mixing.
Water miscible flexible linear preferably is entirely the polymer of aliphatic series, and is preferably unbranched.Can have functional end-group, for example hydroxyl or amino, these groups can participate in the reaction with crosslinking agent.The effect of flexible linear is to regulate the dye affinity of man-made cellulose fibers to be crosslinked the degree that resin reduces, so that the dye affinity of man-made cellulose fibers is more near cotton dye affinity.It seems that this effect be to obtain like this: prevent excessively caving in of cellulosic fibrous structure in the cross-linking reaction process, this structure keeps certain openness thus, and making has enough dyestuffs to enter, and reaches required dye levels.After dyeing, flexible linear does not have further function, tends to flush away from fiber, reaches such degree: because the functional group that relates in the cross-linking reaction, it no longer keeps original position.
The flexible linear of preferred type comprises the glycols of polymerization, for example polypropylene glycol (PPG), particularly polyethylene glycol (PEG).Also can use the derivative of the amine end-blocking of these polymer diols.Should be appreciated that these flexible linear normally have the mixture at the molecule of certain limit chain length, characterize with its mean molecule quantity and chain length.For example, chain length can be in the scope of about 5-150 atom.A preferred example of flexible linear is the PEG of mean molecule quantity in the 200-2000 scope.
Preferably use crosslinking agent, flexible linear and any catalyst to man-made cellulose fibers from solution (the preferably aqueous solution).Polymer diol is as PEG and PPG normally in the water soluble.This solution can be administered on the fiber with known method, for example this solution can be padded on fibre bundle (preferably still undried fibre bundle), and fibre bundle is bathed through the processing of this solution.Also can handle the fiber of staple form.After using solution, still undried fibre bundle (never-dried tow) can have the moisture content of about 45-65 weight %, is generally about 50 weight %.Treatment Solution can contain 0.5-15 weight %, preferably the crosslinking agent of 1.5-5 weight % (is benchmark in 100% activity).This solution preferably contains 0.1-5 weight % flexible linear.When using catalyst, this solution contains 0.1-5 weight %, the catalyst of preferred 0.25-2.5 weight %.This solution can contain one or more additives, for example is used for the soft finishing agent of fiber.
Treated man-made cellulose fibers preferably contains the 0.2-5 weight % in cellulose, is more preferably crosslinking agent and the 0.1-3 weight % flexible linear of 1-4 weight %.
The fabric that is made by man-made cellulose fibers and cotton fiber through dipping can be knitting, woven or non-woven fabric.Under the situation of knitting and woven fabric, earlier with the fiber spun yarn.A kind of preferable methods is man-made cellulose fibers and the cotton fiber that mixes through dipping, again by this mixture spinning.Another kind method is to prepare yarn separately by each fiber, again yarn is mixed and made into fabric.Any mixed proportion that is suitable for required final use all can be used, the part by weight that mixes with cotton usually in 70: 30 to 30: 70 scope, mixture more commonly used 50: 50.
Can before dyeing, carry out crosslinked or curing schedule.If before dyeing, will carry out any other wet process, should before this wet process, carry out crosslinked so to avoid yarn treated in wet treatment step to lose cross-linking chemistry reagent.Preferably, crosslinkedly carrying out on the fabric or on yarn.When the fabric that will obtain is knit goods or supatex fabric, crosslinkedly preferably on fabric, carry out.Yet, when the fabric that will obtain is woven fabric, preferably on yarn, carry out crosslinked because usually the warp sizing operation of carrying out before woven can cause losing on the yarn cross-linking reagent, if these yarns are also uncrosslinked.Carry out crosslinkedly also being fine in fiber stage, but not by preferably, because through can become crinosity and be difficult to process of crosslinked fiber in spinning and fabric fabrication stage.
A kind of preferable methods comprises with flexible linear and crosslinking agent dipping man-made cellulose fibers, to mix with cotton fiber through the fiber of dipping, by the fiber production yarn that mixes, prepare fabric by this yarn, carry out cross-linking reaction on the yarn or on fabric, under the situation of woven fabric, preferably on yarn, carrying out cross-linking reaction.
Crosslinked can being undertaken by a heating steps, the temperature and time of this heating steps will be suitable for used crosslinking agent and catalyst.When carrying out on fabric when crosslinked, this fabric can pass through hot-blast stove on stenter.Suitable crosslinked condition comprises temperature in 140 ℃ to 200 ℃ scope, and the time, as a rule, the heat time heating time of higher temperature was suitably shorter than lower temperature in 30 seconds to 5 minutes scope.
Early stage dried is for example used cross-linking chemistry reagent afterwards to the drying of fibre bundle, should carry out under the condition that mainly is lower temperature, can not take place crosslinked too early under such temperature.For example, the temperature of fiber itself (being different from air themperature) preferably keeps below 110 ℃ in dry run.In addition, preferably fiber drying to moisture content is not lower than about 7 weight % of fibre weight.
The dyeing of fiber can be used dyeing of cellulosic fabric dyestuff and method commonly used are carried out.Suitable dyestuff comprises direct dyes, reducing dye, SULPHUR DYES and REACTIVE DYES.Can use commercially available dyeing machine, comprise the water-jet dyeing machine, for example usually said Thies Ecosoft, the dyeing machine of the dyeing machine of Gaston County Futura and Hisaka Circular CUT-SL, and the aerojet dyeing machine, the dyeing machine of for example usually said Thies Airstream, Thies Luft Roto, Hisaka AJ-1, Krantz Aerodye and Then AFS.
The present invention includes first embodiment of undyed fibre, this fibre comprises cotton fiber and man-made cellulose fibers, wherein with water miscible flexible linear with have and the crosslinking agent of cellulose reactive dipping man-made cellulose fibers, also uncrosslinked but have such potentiality through the man-made cellulose fibers of dipping: can reach when before fiber article dyeing, carrying out the cross-linking reaction between man-made cellulose fibers and the crosslinking agent reduce dyestuff affinity to the potentiality more approaching with the dye affinity of cotton fiber.
First embodiment of undyed fibre can be a cotton fiber and through the undyed fibre blend of man-made cellulose fibers of dipping, the yarn that is made by this fibre blend, the perhaps fabric that is made by this yarn.Can also be by cotton yarn and contain through dipping but the fabric that the yarn of uncrosslinked man-made cellulose fibers makes.
The present invention also comprises second embodiment of undyed fibre, this fibre comprises cotton fiber and man-made cellulose fibers, wherein, with water miscible flexible linear and crosslinking agent dipping man-made cellulose fibers, described crosslinking agent in cross-linking reaction with the fibrin reaction of man-made cellulose fibers, the dye affinity of man-made cellulose fibers is reduced to more level near the dye affinity of cotton fiber.
Second embodiment of undyed fibre is yarn or fabric preferably.Can also be by cotton yarn and the fabric that makes through the yarn of crosslinked man-made cellulose fibers.
