Description
Technical field:
The present invention relates to a kind of polyester slice and preparation method thereof, particularly a kind of high-shrinkage cation normal-pressure easy-to-dye polyester chip and preparation method thereof.
Background technology:
PET industry from the monomeric simple aggregation of beginning binary, develops into the complex art with the compound infiltration of multidisciplinary technology.China is differential, functional polyester is started late, but development rapidly.Supply exceed demand for the normal polyester produce market at present, polyester product is gradually to high performance, material development, the functional polyester of high added value has the attention that specific function more and more causes domestic enterprise and scientific research institutions because of it, the domestic many places of its production technology are in research and development or pilot scale stage, mainly by import.But because the polyester molecule structure has the regularity and the symmetry of height, its degree of crystallinity height, wetting ability is poor, and the group that does not contain close dyestuff, therefore dyeing difficulty generally need be with dispersed dye in High Temperature High Pressure or have under the condition of carrier and could dye, and chromatogram is few, color and luster is bright-coloured inadequately.And can't carry out dyeing at normal temperatures and pressures.Do not possess simultaneously high performance of shrinking yet.In recent years, adopt the modification developing direction that on normal polyester (PET) binary monomer, is added into the 3rd monomer and the 4th monomer formation cation normal-pressure easy-to-dye polyester.But yet there are no and on normal polyester (PET) binary monomer, be added into the 3rd monomer and the 4th monomeric the 5th, the 6th monomer that also adds simultaneously carries out research report aspect the modified technique.
Chinese patent CN101200535 the invention discloses a kind of flame retardant cationic dyeable polyesters and preparation method, and method comprises esterification, polycondensation, and reaction is first monomer and second monomer with terephthalic acid and ethylene glycol; Response type phosphorus flame retardant, the isophthalic acid ester that contains sulphonate-base are respectively the 3rd monomer and the 4th monomer, titanic acid ester as catalyzer, phosphorus compound as stablizer, alkali metal compound as and use additive.Product of the present invention has quite outstanding flame retardant resistance and cationic dye capable of dyeing by the fiber of its spinning, and can guarantee processibility and mechanical property that it is good, and this polyester can be applied to different spinning techniques.
Chinese patent CN1995502 the invention discloses cation easily dyeable composite polyester thick and thin section filament and production method and purposes, product is made through incomplete drafting false twisting processing by the precursor that cationic chromophilous polyethylene terephthalate and common polyethylene terephthalate conjugate spinning obtain, and its length direction at long filament is the alternate form of thickness joint.Production method comprises the precursor that cationic chromophilous polyethylene terephthalate and common polyethylene terephthalate are composited, and makes product through incomplete drafting false twisting processing.Product application is being produced on heterochromatic knitting, the woven fabric.Product cation of the present invention easily dyes the polyethylene terephthalate composition, and has that thickness saves alternate effect, Color is good.
Summary of the invention:
The objective of the invention is characteristics and reasons such as shortage and dyestuff bonded polar group at the polyester macromolecule structure, dyeing is relatively more difficult and can't carry out the problem that dyeing does not possess the highly shrinkable energy simultaneously yet at normal temperatures and pressures, and a kind of high-shrinkage cation normal-pressure easy-to-dye polyester chip and preparation method thereof is provided.
The raw material of preparation high-shrinkage cation normal-pressure easy-to-dye polyester chip is by the pure terephthalic acid, ethylene glycol, the 3rd monomer m-phthalic acid binaryglycol ester-5-sodium sulfonate (SIPE), the 4th monomer polyoxyethylene glycol (PEG), the 5th monomer m-phthalic acid, the smart hexanodioic acid of the 6th monomer, compositions such as catalyst acetic acid antimony and antioxidant, the mass percent that its each raw material is formed is respectively: pure terephthalic acid 66%-68%, ethylene glycol 23%-21%, the 3rd monomer m-phthalic acid binaryglycol ester-5-sodium sulfonate (SIPE) 3.2%-5.5%, the 4th monomer polyoxyethylene glycol (PEG) 2.1%-3.3%, the 5th monomer m-phthalic acid 0.5%-0.7%, the smart hexanodioic acid 3.1%-4% of the 6th monomer, catalyst acetic acid antimony 0.012%-0.036%, antioxidant 0.005%-0.055%, each constituent mass and be 100%.
Process explanation:
The polyester testing apparatus is by an esterifying kettle and the polyester testing apparatus at intermittence that polycondensation vessel is formed.Drop into pure terephthalic acid, ethylene glycol in proportion and add the 4th, the 5th, the 6th monomer and oxidation inhibitor simultaneously in esterifying kettle, control esterifying kettle pressure is at 0.25MP-0.3Mpa.When reflecting the water yield and reach 100-130ml, add ethylene glycol to oligopolymer depolymerization homogenizing, the esterifying kettle temperature is controlled at 250-260 ℃, react after 15-35 minute, add the 3rd monomer in polycondensation, join in the polycondensation vessel with catalyst acetic acid antimony, thermo-stabilizer trimethyl phosphite 99, this moment, the polycondensation vessel temperature was about 230-270 ℃.Enter the rough vacuum that the vacuum meter reading is 0.01-0.076Mpa then, after carrying out rough vacuum 20-45 minute, begin to enter the high vacuum that the vacuum meter reading is 0.08-0.098Mpa, after temperature reaches 272-278 ℃, stop heating and keep constant temperature, when discharging power reaches 110-150KW, stop to stir beginning discharging granulation.
The invention provides a kind of high-shrinkage cation normal-pressure easy-to-dye polyester chip and preparation method thereof, utilization is on the monomeric basis of normal polyester (PET) binary, adopt direct esterification technology, and add the 3rd monomer m-phthalic acid binaryglycol ester-5-sodium sulfonate (SIPE) and other material, prepare a kind of high-shrinkage cation normal-pressure easy-to-dye polyester chip through esterification and polycondensation.Because it has introduced the 4th monomer polyoxyethylene glycol (PEG) again when introducing SIPE, the kindliness of PEG molecular chain has further been destroyed molecular chain regularity and crystal property, has increased non-crystalline region, improve the macromolecular activity performance of non-crystalline region, obtained the effect that cation normal-pressure boils and dyes.Add the 5th, the 6th monomer on this basis again, increased high contractile function.The boiling water shrinkage of the fiber of product spinning of the present invention has improved 20% in 41.5% boiling water shrinkage than general fibre, makes the high-shrinkage cation normal-pressure easy-to-dye polyester chip of preparing have the highly shrinkable energy, anti pilling, anti-fluffing, light-weighted characteristic.
The invention effect
The high-shrinkage cation normal-pressure easy-to-dye polyester chip that the present invention is prepared and preparation method thereof polyester slice can boil at normal temperatures and pressures and dye, dye uptake and dye exhausting rate height.Dyed fiber and fabric color is bright-coloured, chromatogram is complete, and have good highly shrinkable energy and an anti-pilling property, have better spinnability and drawdown simultaneously, characteristics such as the physicals of fiber and post-treatment are good, but this section direct fabrics, suitability for industrialized production such as weave cotton cloth.
