Abstract
The invention relates to a supercritical carbon dioxide dyeing process for finishing and pre-treating aramid fiber/viscose blended fabric polyethylene glycol. A good washing fastness is achieved after dyeing aramid fiber/viscose by supercritical carbon dioxide; the K/S value of the dyed fabric reaches 17; the dry rubbing fastness reaches a grade V; the wet rubbing fastness reaches the grade IV-V; the high-temperature color distortion fastness reaches a grade V. The supercritical CO2 dyeing process causes no damage to the warp and weft breakage strength of the fabric; conversely, the strength of the dyed fabric is higher than that of the fabric in the prior art; the fabric is few in surface floating color, so that the operation for washing the floating color is not required.
Description
Technical field
The present invention relates to field of textiles, be specifically related to a kind of aramid fiber/viscose blend fabric polyethylene glycol and arrange pretreated supercritical CO 2 dyeing technique.
Background technology
Water is at a kind of very important medium of traditional dyeing process pilot scale, soak and swollen fiber with water, using water as solvent, dispersant or dye carrier, also the follow-up works such as cleaning will be carried out after having dyeed, at substantial water resource, the dyestuff of a large amount of non-set of good friend in the waste water of discharge after dyeing and auxiliary agent, and have some heavy metals, serious pollution is caused to environment.Along with water resource growing tension, particularly the improving constantly of people's environmental consciousness, traditional staining technique is challenged, people pursue without water or the pollution-free new dyeing technology using water less. and supercritical CO 2 staining technique has met these requirements just, water pollutions has been stopped, for specifying direction as the dyeing and finishing industry of draining rich and influential family from source.
Supercritical CO 2 dyeing has the following advantages compared with dyeing with traditional water bath: (1) can realize non-aqueous dyeing truly, has stopped water pollution problems, protection of the environment from source, fresh-water-saving resource; (2) dyestuff recoverable, and without the need to adding the auxiliary agents such as dispersant, levelling agent, detergent in dyeing course, saved dyeing cost; (3) dyeing need not carry out the operation such as reduction cleaning, oven dry after terminating, and simplifies dyeing, reduces energy consumption; (4) carbon dioxide is nontoxic, fabric face noresidue after dyeing, and can recycle, and can not cause greenhouse effects, to environment without any harm; (5) have dye amount and good level-dyeing property on good dyestuff, reproducibility is good; (6) some more chromophobe fibers in conventional water-bath dyeing, as polypropylene fibre etc., also can realize good dyeing; (7) dyeing arrival balance required time is short, greatly can shorten dyeing cycle, enhance productivity.
As from the foregoing, the dyeing of a kind of efficient, environmental protection during supercritical CO 2 dyeing.Therefore, it is feasible that supercritical CO 2 staining technique is applied to printing and dyeing industry, and has huge development potentiality.
Aramid fiber is that the main chain of polymer macromolecule is made up of aromatic rings and amido link, and wherein the amide groups Direct Bonding of at least 85% is on aromatic rings, the nitrogen-atoms in the amide groups of each repetitive and carbonyl are all directly connected with the carbon atom in aromatic rings and replace the polymer of one of them hydrogen atom.Aramid fiber is a kind of high strength, high-modulus, low-density and the good heat-proof combustion-resistant fiber of ABRASION RESISTANCE.
Viscose is mainly with the regenerated celulose fibre that cotton or wood are produced for raw material, and viscose has " cotton essence, the quality of silk ", is genuine ecological fiber.It comes from sky but is better than natural, is therefore widely used in the aspect such as textile garment fabric and trimming cloth.Viscose is widely used in silk, weaves, knitting, braiding and line processed, making herbs into wool industry, rayon lining twill, Fu Chunfang and various silk quilt covers etc. can be made into separately, can interweave with fibers such as hair, fiber crops, silks again, also can be woven into camlet, soft silk and shameuse etc. with cotton yarn, silk, synthetic fiber.Because it is comfortable and easy to wear, be particularly suitable for making underwear.
The BLENDED FABRIC of aramid fiber and viscose glue has soft feel, good bulkiness, drapability, sucting wet air permeability and good mechanical property, ABRASION RESISTANCE, good dyeability, good cloth cover fineness, COLOR FASTNESS and chance live charcoalization do not melt good characteristics such as dripping, can meet the quality requirement of medium-to-high grade flame-resistant garment, decorative fabric.Viscose generally uses reactive dyeing, and dyeing is similar to cotton.Every COLOR FASTNESS of DYED FABRICS is better.
The special research for aramid fiber/viscose fabric dyeing is fewer at present, and is by DISPERSE DYES and REACTIVE DYES one-bath dyeing to the main method of its dyeing, or is dyeed to it by the DISPERSE DYES with active group.
Mainly there is following problem in current staining conditions: (1) through-dyeing: there is a large amount of aromatic rings in aramid fiber 1313 strand, make its internal structure closely, and vitrification point is very high again, thus still cannot by fiber imbue under test high-temperature and high-pressure conditions; (2) light fastness: common High Temperature High Pressure cannot solve a difficult problem for aramid fiber light fastness difference; (3) depth: aramid fiber dyes, mostly just middle light.
Special also not reporting for aramid fiber/viscose fabric supercritical CO 2 dyeing at present.
Summary of the invention
