Description
Technical field
The present invention relates to a kind of azo structure carboxylic amide type dyes for polylactic acid fiber dyeing and preparation method thereof that is applicable to.
Background technology
Trevira mainly comprises polyethylene terephthalate (PET), Poly(Trimethylene Terephthalate) (PTT), polybutylene terephthalate (PBT) and emerging poly(lactic acid) (PLA) fiber, this fibrid has high-crystallinity usually, therefore no strongly hydrophilic group in the molecular backbone chain presents hydrophobicity.The trevira spin-drawing and pre-thermally-stabilised after, the molecular layer that the surface has one deck to align, be difficult for penetrating, and lacking in the molecular structure and dyestuff generation bonded active group, therefore dyeing difficulty.The trevira molecular arrangement is neat, and when temperature was low, the macromolecular chain segment motion was inactive, and the space is less; In addition, be suitable for not having water miscible sulfonic acid group, hydroxy-acid group plasma group in the painted dispersed dye molecule of trevira, it is the nonionic dye that a class is insoluble in water, need under the dispersion agent effect, be scattered in the water with insoluble minuteness particle, usually the aggregate form with a plurality of dye molecules exists, and dye granule is bigger.When in water medium, dyeing, trevira can not resemble the cotton fibre and by violent swelling the space be increased, dye granule is difficult to be penetrated at short notice fibrous inside, needs to realize dying by kinetic energy that improves dye molecule and the method that fortifying fibre macromolecular chain segment mobility enlarges the fiber hole in the trevira dyeing course.Therefore dispersed dye main high temperature and high pressure method, thermosoling, support methods of adopting on trevira dyes.The PET dyeing temperature is 130 ℃; Most of dispersed dye all have the dye uptake above 90% on PET.
As a kind of emerging environment-friendly type polyester fiber, acid fiber by polylactic has excellent biological compatibility, absorbability, degradability, heat impedance and anti-ultraviolet function.Along with the exploitation of low-cost novel process, acid fiber by polylactic is applied in fields such as textiles, biomedicine and packings.But many dispersed dye dyeing behavioies on acid fiber by polylactic at excellent performance on the polyster fibre are not good, cause the scarcity of acid fiber by polylactic suitable dyes.Since acid fiber by polylactic was realized suitability for industrialized production, Chinese scholars had been carried out big quantity research to the physicochemical property of acid fiber by polylactic.Aspect dyeing, generally believe that dispersed dye are more suitable for the painted of acid fiber by polylactic.Yang etc. once studied the dyeing condition and the dyeing behavior of dispersed dye on acid fiber by polylactic commonly used, for avoiding the acid fiber by polylactic hydrolysis to influence its intensity and Color, suggestion poly(lactic acid) fabric dyes in acidulous dye bath (pH5~6), temperature is no more than 110 ℃, and dyeing time is no more than 45min.
Qian Hong flies to wait and has studied the dispersed dye molecular structure to the polylactic acid fiber dyeing Effect on Performance, and contrasts with coloration result on the polyster fibre.Because acid fiber by polylactic and polyster fibre all exist aspect molecular structure and the dyeing than big-difference, most of terylene are on the low side with dispersed dye dye uptake and colour fastness on acid fiber by polylactic, are difficult to satisfy and take requirement.After dying fiber on the dispersed dye, dyestuff and fiber are to combine by more weak Van der Waals force.Van der Waals force is big, and dyestuff is the avidity height on fiber, and colour fastness is good, shows as high dye uptake; Otherwise colour fastness is poor, and dye uptake is low.No aromatic ring and have more relatively ester group on the polylactic acid molecule chain is given certain polarity of acid fiber by polylactic molecular chain and kindliness preferably.If in dye molecule, introduce polar group, these polar groups can and acid fiber by polylactic macromole generation dipolar forces, hydrogen bonded improve Van der Waals force between dyestuff and fiber molecule, help improving the dye uptake and the colour fastness of dyestuff.Studies show that the dye uptake of azoic dye and the substituent kind in the molecule have dependency, have the dyestuff of carboxylic acid ester groups in the molecular structure, dye uptake is generally higher.Dyestuff similar to the molecular structure of fiber (all having the such polarity dots of ester group) is described, helps dying on the dyestuff.
Zhang Shufen etc. had once developed a class hydrophobic fibre slightly water-soluble sulfonamide type dye, and this dyestuff gives dyestuff different avidity by the chain length of regulating the straight chained alkyl that sulfoamido connected, thereby is applicable to the dyeing of different hydrophobic fibres; Increase the linearity of dyestuff by means of the linear structure of straight chained alkyl, thereby improve the affinity of dyestuff and fiber, improve the tinting strength and the colour fastness of dyestuff; In dye structure, introduce the sulphonamide polar group, not only can give the dyestuff slightly water-soluble, thereby the molecular polarity that has also increased dyestuff helps improving the fastness to sublimation of dyestuff.This class dyestuff synthesis technique is simple, can synthesize the slightly water-soluble sulfonamide type dye that contains straight chained alkyl by sulfonating chlorinating, aminolysis reaction or diazotization, coupled reaction, and it is used for the dyeing of hydrophobic fibre terylene, polypropylene fibre and acid fiber by polylactic, when improving dye utilization rate, also can give coloured fibre preferable colour fastness.
In sum, poly(lactic acid) (PLA) fiber belongs to a kind of more emerging trevira, and is a lot of not good at dye uptake and the colour fastness of the good dispersed dye of coloration result on the PET fiber on the PLA fiber.How to design a kind of dyestuff that can on the PLA fiber, present preferable coloration result, become the industry and urgently wish the problem that solves.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of azo structure carboxylic amide type dyes for polylactic acid fiber dyeing and preparation method thereof that is applicable to, uses this kind dyestuff can improve dye uptake and colour fastness on the PLA fiber.
In order to solve the problems of the technologies described above, the invention provides a kind of azo structure carboxylic amide type dyes for polylactic acid fiber dyeing, contain carboxylacyl amine group in its molecular structure, its general structure is as follows:
