Summary of the invention
At problem and defective that above-mentioned prior art exists, the object of the invention provides a kind of with the technology of supercritical fluid to the fabric art dyeing, makes the DYED FABRICS that has artistic color pattern.
The anhydrous art dyeing technology of described supercritical carbon dioxide, be in a part device, to utilize supercritical carbon dioxide fluid as dyeing medium, the technology that fabric after making the dyestuff that is dissolved in wherein to embroider dyes is promptly dyed to such an extent that have a method of floral designs fabric under anhydrous condition.
The technical solution adopted for the present invention to solve the technical problems is: with the requirement of non-target product dyed thereby by artistic color pattern, hide part and treat that the colouring method of dyeing and weaving thing makes.At first be to utilize pin, line, rope, wooden stick and medium-thick type cotton to treat the dyeing and weaving thing to carry out embroider by designed with patterns, make its by style hide treat the dyeing and weaving thing do not need by on dye part, to reach the purpose that presents decorative pattern or pattern at last.Then the fabric behind DISPERSE DYES and above-mentioned " embroider " is positioned in the supercritical CO 2 dyeing device, under set process conditions, realizes supercritical CO 2 dyeing.A little less than the general molecular polarity of DISPERSE DYES, molecular weight is also little, thereby is soluble in the supercritical carbon dioxide.DYED FABRICS is terylene and washs hair, polyester cotton.It is polar molecule that cotton fiber is tieed up plain molecule, and DISPERSE DYES polarity is low, and the affinity of dyestuff and fiber is low, dyes the COLOR FASTNESS of cotton fabric with DISPERSE DYES and dyes the low of other kind fabric.But the adhesion of terylene and DISPERSE DYES is strong, dye fabric COLOR FASTNESS height, so polyester cotton still can reach the finished product requirement.In dyeing course, dyestuff at first is dissolved in the supercritical carbon dioxide fluid, and the dyestuff of dissolving flows gradually near fiber interface with dye liquor; Because there is the Dynamic Boundary layer that is difficult to flow in fiber interface, dyestuff advances people's Dynamic Boundary layer.Near fiber interface behind certain distance, mainly by self diffusion near fiber, dyestuff near fiber interface to the molecular force between them enough greatly after, dyestuff is adsorbed by fiber surface rapidly; After dyestuff is adsorbed to fiber surface, produce a concentration difference or inside and outside dyestuff chemistry potential difference inside and outside fiber, dyestuff will be to the fibrous inside diffusion transfer.The dyestuff that is dissolved in supercritical carbon dioxide is the mixed and disorderly dispersity of unimolecule more.Dyeing in this state, the dyestuff in the dye bath is active.And carbon dioxide has high diffusion coefficient, and dye molecule is diffused in the hole of fiber apace, makes dyestuff fast, dye the position that fabric is not tied covering on equably.And tie up covering place because the barrier effect of bundle makes the dyestuff can not be near by the fiber interface of dyeing and weaving thing.Dyestuff can not be adsorbed by fiber surface, thereby dyestuff can not be gone up covering place of tying up of dyeing and weaving thing.Final fabric presents the pattern of white or light color.Release of pressure was to reclaim carbon dioxide and excess dye after dyeing was finished.
Concrete technological process is: at first treat the dyeing and weaving thing and carry out " embroider ", be to utilize pin, line, rope, wooden stick, medium-thick type cotton or its mixing to use exactly, treat the dyeing and weaving thing by designed with patterns and carry out embroider, its style by pattern is hidden treat that the dyeing and weaving thing is not dyed part on the dyestuff, and be fixed on the distributor; The described dyeing and weaving thing embroider for the treatment of is: will treat that the dyeing and weaving thing is scooped up bundle, string is pricked, folded and prick, knit, tie up and mixed method processing to be dyed.Wherein
Described pinch of bundle is the circle that draws on fabric and differ in size, and in the center of each circle fabric seized, and is that the boundary wraps up the place of having seized tight with cotton with the circumference; It is will treat that with needlework the dyeing and weaving thing needs the sideline string seam at resist printing position that described string is pricked, and behind the string seam line is taken out tightly, and making needs resist printing place to be pugil, with cotton that its wrapping is tight again; Described folded bundle is earlier will be fabric folded with irregular asymmetric method or rope, and will fold with cotton thread then or stubborn fabric of getting well is fixed on the wooden stick or directly is fixed on the distributor; Described braiding is will to treat dyeing and weaving thing and rope or/and medium-thick type cotton bar is woven into pigtail or twisted shape, and rope and middle grey sheeting bar are 1～3; Described tying up is with rope or/and medium-thick type cotton bar will treat that the dyeing and weaving thing needs resist printing place to twine binding, and rope and middle grey sheeting bar are 1～3.Behind the embroider, successively with dyestuff, be fixed on treating on the distributor and dye the embroider arrangement and go in the supercritical carbon dioxide dyeing apparatus.With the heating of supercritical dyeing device, making its temperature is 70～150 ℃, and it is 18～30MPa that the unlatching high-pressure system makes its pressure, dyes with this understanding, and the time is 50～100min.Dyeing finishes back release of pressure, cooling, makes it remain on the recovery of carrying out carbon dioxide and dyestuff under the 4～5MPa, 25～40 ℃; Then coloring system is lowered the temperature, is depressurized to normality, take out the fabric after dyeing, remove line, rope and medium-thick type cotton overcover, with the smooth fabric that has various floral designs that promptly gets of art dyeing fabric flatiron.The described dyeing and weaving thing for the treatment of is terylene and washs hair, polyester cotton; Described dyestuff is a DISPERSE DYES.
According to GB/T.3921.1-1997 textile color stability test color fastness to washing, fabric COLOR FASTNESS test analysis is carried out in the evaluation of GB7565-87 textile color stability test cotton and viscose glue STANDARD ADJACENT FABRIC specification and GB6151-857 textile color stability test COLOR FASTNESS.The result shows the colour fastness to rubbing dye the back fabric and water-fastly washes the requirement that COLOR FASTNESS all can reach GB18401-2003 " national textile product basic security technical specification ", and colour fasteness to rubbing can reach 3～4 grades, and the water-fast COLOR FASTNESS of washing can reach 3～5 grades.
Compared with prior art, the present invention's characteristics of giving prominence to are: realize fabric is carried out anhydrous art dyeing.Make and dye the floral designs that the back fabric has white or light color, artistic effect is strong, dyeing quality good, and technological process is short, realizes the production that cleans of no reject product, non-environmental-pollution, and integrated cost is low, the characteristics of economic benefit, obvious environment benefit.
