Description
Technical field
The invention belongs to dyestuff synthetic and textile dyeing and finishing field, particularly relate to antibacterial cation reactive dye and preparation method thereof.
Background technology
The dyeing of textiles is two important wet courses of processing with arrangement, and traditional textile dyeing and arrangement are separately carried out, and exists the shortcoming of expensive, high energy consumption and large amount of sewage discharging.With the dyeing and finishing processing technology that dyeing and functional treatment are finished in bathes, for reducing production costs, save energy reduces discharge of wastewater, preserves the ecological environment etc. to have great importance.Therefore, many experts both domestic and external have carried out many researchs in the field, aspect dyeing and antistatic, fire-retardant, antiultraviolet, shrinkproof and research that wrinkle proofing is finished in a bath, have obtained certain achievement.Yet, as a rule, because dyeing different with the finishing technique condition, need under the alkaline condition fixation to finish usually as reactive dyeing, and the resin wrinkle proofing needs an acidic catalyst, makes the use of this technology have bigger limitation.Antibacterial dye belongs to a kind of of functional dyestuff, and in recent years, because its weather resistance, simple for process and ecological, environmental protective etc. are paid close attention in the antibacterial finish of textiles more, therefore, such dyestuff has caused that people more and more pay attention to.
The antibacterial finish of textiles at present exists many shortcomings, as poor durability; Adopt resin or tackiness agent can make fabric feeling descend color change; The fabric Long contact time of human body and process antibacterial finish can form dermatitis; The relief liquor of antibacterial finish is as dealing with improperly in the factory, can destroy the probiotics in the environment and causes ecological problem etc.
The functional dyestuff that has good dyefastness on textiles is a kind of ideal antibacterial finishing agent, both at home and abroad to this report and few.The foreign scholar adopts aminoanthraquinone as dye matrix, and quaternary ammonium salt has synthesized a series of cationic antimicrobial dyestuffs as antibacterial components, and nylon and acrylic fabric have been carried out successfully dyeing, has obtained better anti-bacterial effect.But this dyestuff lacks avidity to cotton fibre, and owing to quaternary ammonium moiety in the molecule combines by amido linkage with dye matrix, hydrolysis easily, and make dyestuff lose anti-microbial property.
Antibacterial cation reactive dye (chemically-reactive dyes) is mainly used in cellulosic fibre, also can be used for protein fibre, tynex, polyacrylonitrile fibre and cationic dyeable polyester fiber.Antibiotic part in the dyestuff adopts quaternary ammonium salt structure, mainly is based on quaternary ammonium salt to human body safety, has broad spectrum antibacterial, can not cause mutation and the resistance of bacterium, the most important thing is and can combine with dye matrix, forms to have water miscible cationic dyestuff.
Summary of the invention
The objective of the invention is based on reactive dyestuffs the excellent dyeing behavior of cotton fibre and the sterilization mechanism of quaternary ammonium salt, reactive dyestuffs and quaternary ammonium salt bactericide group are combined, antibacterial cation reactive dye and preparation method thereof is provided, can dye and antibacterial finish to other fibers commonly used of cellulose fiber peacekeeping, have high antibacterial effect, make dyeing with antibacterial finish once finish and dyefastness good, antibiotic durable.
The molecular structure that antibacterial cation activity of the present invention is dyed is by the anthraquinone dye parent, the s-triazine active group is formed with the quaternary ammonium moiety with long carbochain, it is characterized in that such dyestuff is mainly used in the dyeing and the antibacterial finish of cellulosic fibre, short the dying that does not need neutral electrolyte (as sodium-chlor and sodium sulfate) when being used for cellulose dyeing, also can be used for protein fibre (as wool, silk etc.), tynex is (as nylon 66, nylon 6), acrylic fibers, the dyeing of fibers such as cation dyeable polyester and antibacterial finish, such dyestuff has very high anti-microbial property in solution or on the fiber, such dyestuff has very high avidity (absorption property) to above fiber, and has good every dyeing colour fastness.Chemical structure is as follows:

The preparation method that antibacterial cation activity of the present invention is dyed comprises the steps:
A. aminoanthraquinone A and trichlorine or trifluoro s-triazine are dissolved in the oil of mirbane organic solvent, with mixture heating up to 90 ℃, after 1 hour temperature is risen to 120 ℃, continuing stirring about 1 hour under this temperature, be cooled to 25-30 ℃, filter dyestuff intermediate B, methanol wash, dry in the vacuum drying device;
B. the dyestuff intermediate B with step a preparation is dissolved in DMF (N, the dinethylformamide) organic solvent, adds tertiary amines intermediate C in this mixture, in 55 ℃ of reactions 3-4 hour, reaction finished, and boils off solvent DMF in vacuum-evaporator, get dyestuff intermediate D, dry in the vacuum drying device;
C. step b is made to such an extent that dyestuff intermediate D is dissolved in the DMF organic solvent, in this mixture, add haloalkyl E, about reacting by heating mixture to 120 ℃, reacted 4-5 hour, reaction finishes, and boils off solvent DMF in vacuum-evaporator, the ether washing, ether-alcohol mixed solvent recrystallization gets dyestuff F, vacuum-drying in the vacuum drying oven.
The invention has the beneficial effects as follows: antibacterial cation reactive dye not only can be mainly used in cellulosic fibre, also can be used for the dyeing and the antibacterial finish of protein fibre, tynex, polyacrylonitrile fibre and cationic dyeable polyester fiber, have good dyeing affinity and antibiotic weather resistance, and dyeing and antibacterial finish are once finished, water saving, energy-conservation, ecological, environmental protective.
Embodiment
Provided by the invention have the active cationic dye of antibacterial and the dyeing mechanism that the preparation method has mainly utilized reactive dyestuffs and the antibiotic mechanism of quaternary ammonium salt, and the preparation method is based on the principle of acylations and alkylated reaction.Different with other antibacterial cation dyestuff, antibacterial cation reactive dye provided by the invention is except dyeing to cellulosic fibre and giving the antibacterial, can also finish dyeing and antibacterial finish simultaneously to protein fibre, tynex, polyacrylonitrile fibre and cationic dyeable polyester fiber, improve the range of application of such dyestuff.In addition, owing to have bigger hydrophobic group in such dye molecule, its affinity to bacterial cell membrane is improved, dyestuff antiseptic-germicide molecule combines with bacterial micro-organism easily, be convenient to the cytolemma that long hydrophobic carbochain pierces through bacterium, thereby bacterium is lost activity, and the general quaternary ammonium salt antiseptic of anti-microbial property is improved.
Following illustrative embodiment helps further to understand the present invention.
