Detailed description of the invention
Below by detailed description of the invention, the present invention is described in further detail.But it will be understood to those of skill in the art that the following example only for illustration of the present invention, and should not be considered as limiting scope of the present invention.Unreceipted concrete technology or condition person in embodiment, according to the technology described by the document in this area or condition (such as with reference to " dyeing and finishing technology and principle " that Zhao Tao writes, China Textiles Press, 2009) or carry out according to product description.Agents useful for same or the unreceipted production firm person of instrument, being can by the conventional products of commercial acquisition.
The present invention utilizes cotton fiber and the difference between nylon fibre microstructure and reactive group, the number of REACTIVE DYES water soluble group, the size of molecular weight, the applicability of reactive group, control the upper dye of different dyes on different fiber and reaction, reach homochromy or the effect of extraordinary splendor.
When being dyeed by one-bath one-step dyeing to cotton fiber and nylon fibre, the dyestuff selected can be at least one in following three kinds: the first, the dyestuff to cotton fiber dyeing capacity is better than to polyamide fibre dyeing capacity; The second, the dyestuff to polyamide fibre dyeing capacity is better than to cotton fiber dyeing capacity; The third, to polyamide fibre dyeing capacity substantially close to the dyestuff to cotton fiber dyeing capacity.In one embodiment, composite dyestuff forms by the dyestuff of the described dyestuff of the first and the second is composite; In this fashion, the first dyestuff can dye to polyamide fibre and preferably not to cotton fiber dyeing, and the second dyestuff can dye to cotton fiber and preferably substantially not to nylon dyeing, just achieve the difference utilizing the upper Dry Sack of cotton brocade, produce " sudden strain of a muscle look " fabric, cotton bright and beautiful intertexture jacquard fabric utilizes the difference of gloss and color between polyamide fibre and cotton, comes third dimension and the stereovision of outstanding flower pattern, forms good visual effect.In another one embodiment, adopt the third above-mentioned dyestuff separately, just can realize the bulk dyeing to fabric, form homogeneous color.In another one embodiment, the first and the third dyestuff can be adopted to carry out composite dyeing; Or adopt the second and the third dyestuff to carry out composite dyeing.
More particularly:
The first dyestuff dyestuff is selected from the dyestuff with alpha-brominated acrylamide active group or has in the vinyl sulfone(RemzaolHuo Xingranliaohuoxingjituan) active base dye of sulfonic group water soluble group.Such as: active red 120, active blue 19, active yellow 39, active red 84.
The second dyestuff is selected from this following four class: the first kind, one or more in two chloro-s-triazines of bridge-type or a two fluorine s-triazine or two nicotinic acid s-triazine REACTIVE DYES; Equations of The Second Kind, has formazan structure or triphendioxazine structure in precursor structure, active group is one or more (such as: REACTIVE Blue 21 6, reactive blue 268) in nicotinic acid s-triazine or a fluorine s-triazine or vinyl sulfone(RemzaolHuo Xingranliaohuoxingjituan) or a chloro-s-triazine; 3rd class, parent is azo metal chelation structure, and active group is one or more (such as Reactive Red 2s 71) in a chloro-s-triazine or a fluorine s-triazine or nicotinic acid s-triazine; 4th class, parent contains 4 water soluble groups or more than 4-SO
3group, active group is one or more in a fluorine s-triazine or vinyl sulfone(RemzaolHuo Xingranliaohuoxingjituan) or a chloro-s-triazine.
The third dyestuff is selected from parent and is monoazo structure and contains 2 ~ 3-SO
2group, active group are the dyestuff of one or more in nicotinic acid s-triazine or a fluorine s-triazine or vinyl sulfone(RemzaolHuo Xingranliaohuoxingjituan) or a chloro-s-triazine.Such as: active yellow 167, REACTIVE Orange 122, active red 15, active yellow 176.
Above composite dyestuff can avoid the main cause of staining to include in dyeing course:
(1) nylon fibre is poor relative to cotton fiber hydrophily, so produce hydrogen bond and Van der Waals force with hydrophobic dyestuff, some contain the fewer dyestuff of water soluble group, nylon fibre has higher dye-uptake, and the active group in REACTIVE DYES and the amino on nylon fibre produce the combination of covalent bond, reach higher dye-uptake and excellent COLOR FASTNESS.Such as active blue 19, only have a hydrophilic radical in the basic conditions, and molecule is less, has very high upper dye and degree of fixation for polyamide fibre.
Because nylon fibre has core-skin Rotating fields, the top layer degree of orientation of fiber is higher, the dyestuff that molecule is larger is difficult to pass through, simultaneously, the dyestuff that molecule is larger has higher affinity for cotton fiber, such as, so fewer and have higher dye-uptake to cotton fiber, Reactive Red 2 71 to polyamide fibre staining, almost staining is not had for polyamide fibre, and there is higher dye-uptake on cotton fiber.
(2) reactive group of nylon fibre is amino, the dyestuff with ɑ-bromo acrylamide active group can only produce the combination of covalent bond with the amino on nylon fibre, but the hydroxyl on cotton fiber is difficult to react, so this kind of dyestuff can only react with polyamide fibre, can not set on cotton fiber.Such as active red red 84, active group is ɑ-bromo acrylamide, nylon fibre has very high dye-uptake and excellent every COLOR FASTNESS, and does not almost have staining for cotton fiber.
(3) some REACTIVE DYES, there is molecular size all the time and water soluble group, active group can either produce the combination of covalent bond with the hydroxyl on cotton fiber, also the combination of covalent bond can be produced with the amino on polyamide fibre, dye two kinds of fibers can be gone up simultaneously and produce the combination of covalent bond, such as active yellow 167, active red 15.
(4) selective staining temperature is under 80 ~ 98 DEG C of conditions, nylon fibre cortex appropriateness is expanded, and the dyestuff of upper dye polyamide fibre can pass through cortex, enters fibrous inside, the reactive group of REACTIVE DYES simultaneously, produces the combination of covalent bond with the amino on nylon fibre at this temperature.And the dyestuff of upper dye cotton fiber produces the combination of covalent bond with the hydroxyl on cotton fiber at this temperature.Temperature is too low, the cortex of nylon fibre can not be expanded, and the kinetic energy of dye molecule is not enough, and the REACTIVE DYES of upper dye nylon fibre does not combine by cortex and fiber, and, sufficient activation energy can not be provided to make the amino on REACTIVE DYES and nylon fibre produce the combination of covalent bond.REACTIVE DYES on cotton fiber is also like this, because temperature is too low, the hydroxyl on cotton fiber and the reactive group of REACTIVE DYES can not react normally, causes that degree of fixation is low, loose colour is many, Dry Sack is shallow.Temperature is too high, and dyestuff is easy to hydrolysis, can cause the decline of degree of fixation equally, and the REACTIVE DYES that on some, dye is cotton, because the excessively expanded and upper dye polyamide fibre of polyamide fibre cortex, color can not well control.
(5) soda ash consumption is at 0 ~ 5g.L
-1in the basic conditions, nylon fibre is electronegative, REACTIVE DYES the sulfonic group (-SO of dye cotton fiber
3 2-) more, so the coulomb repulsion produced is comparatively large, prevent from further contaminating the contamination of cotton REACTIVE DYES to polyamide fibre.Amino on upper dye polyamide fibre REACTIVE DYES and nylon fibre, the hydroxyl on the REACTIVE DYES of upper dye cotton and cotton fiber, in the basic conditions, more easily produces the combination of covalent bond.Alkalescence can not be excessively strong, otherwise cause the hydrolysis of REACTIVE DYES, reacts too fast, and Dry Sack is wayward and produce the irregular phenomenon of Dry Sack.And for the dyestuff of nicotinic acid s-triazine and alpha-brominated acrylic amide, just can carry out the combination of covalent bond in neutral conditions, so can not add soda ash, soda ash consumption is 0g.L
-1, and for the lower two chloro-s-triazine REACTIVE DYES of reactivity, soda ash consumption can add to 5g.L at most
-1.
When adopting above-mentioned dyeing, co-bathing dyeing that is cotton and polyamide fibre can be realized, can color better on chain of command and polyamide fibre.Such as, extraordinary splendor dyes, for nylon fibre, the dyestuff of upper dye nylon fibre is in the process of upper dye, can avoid contaminating cotton and REACTIVE DYES to the contamination of polyamide fibre, one side is the dye seat that the dyestuff of upper dye polyamide fibre preferentially captures on polyamide fibre, avoid contaminating in cotton REACTIVE DYES and contaminate, on the other hand, even if the REACTIVE DYES of dye cotton has upper dye polyamide fibre, in upper dye process afterwards, because the affinity of cotton reactive dye to cotton is greater than the affinity of polyamide fibre and shifts, simultaneously, the affinity of polyamide fibre REACTIVE DYES to polyamide fibre is greater than cotton reactive dye and displaces cotton reactive dye to the affinity of polyamide fibre, cotton reactive dye is made to transfer to contaminate cotton fiber.And in two-bath process, the REACTIVE DYES of upper dye polyamide fibre preferentially captures the advantage contaminating seat and displaced the cotton reactive dye above contaminated on polyamide fibre not to be had, so the dyestuff staiing nylon fibre is more, the dyeing of extraordinary splendor is more difficult comparatively speaking.
Only need to adjust rational dye combinations, reach extraordinary splendor or homochromy effect, color is easy to control, practical simple, need not adjusting process condition back and forth, as temperature, pH value, is convenient to actual plant produced.
