Description
Technical field
The present invention relates to a kind of normal pressure cation dyeable polyester fiber and production method thereof.
Background technology
Polyester fiber is a kind of welcome textile material, and not only intensity height, modulus height, elasticity and light resistance are good for it, and good DIMENSIONAL STABILITY is arranged, and flatiron back rivel is lasting.But owing to lack the functional group that directly combines in the strand with dyestuff, thereby can only use disperse dyeing, again because crystallizing polyester degree height, structure is tight, although have energy and DISPERSE DYES to form the ester group of hydrogen bond, dye molecule only just can enter fibrous inside under high temperature, high pressure, and product shade, style and performance are all restricted.For solving polyester fiber this difficult problem that dyes, Chinese scholars has been done a large amount of research, and concluding main method has: original liquid coloring method, master batch colouring, direct injection, disperse dye normal pressure dyeable polyester (EDDP), cation dyeable polyester (CDP and ECDP), anionic dye normal pressure dyeable polyester (EADP) etc.Wherein cation dyeable polyester mainly is to introduce electronegative sulfonic acid group in strand, when dyeing metal ion easily and the CATION in the cation dyes exchange, discharge salt in the time of dyeing.But the cationic fiber dyeing condition needs High Temperature High Pressure, can not with natural fabric union dyeing such as wool.
Patent CN02110770.X discloses a kind of cation dye easy-dying copolyester and fiber, and this polyester is to reach the effect of dying by introducing the reflection of sulfonic acid group and cation dyes, but the fibre strength of spinning is on the low side, and practical value is not obvious.
Patent 200410060520.8 discloses a kind of preparation method of cationic dye deep dyeing copolyester at normal pressure; this polyester is by adding polybasic carboxylic acid; perhaps poly alkylene glycol reaches normal pressure and can dye effect; but adopt antimonous oxide to make catalyst in this polyester process; contain the plurality of heavy metal ion in the waste liquid after the polymerization reflection; environment is caused severe contamination, protect in future under the main trend of environment, will be eliminated.
Summary of the invention
The purpose of this invention is to provide a kind of Color good normal pressure cation dyeable polyester fiber and production method thereof.
Technical solution of the present invention is:
A kind of normal pressure cation dyeable polyester fiber adopts non-antimony-based catalyst in the fibre-forming polymer building-up process of this polyester fiber; With respect to the fibre-forming polymer total amount, the combined polymerization composition is that the molecular weight of poly-dihydric alcohol is 1000～10000, and addition is that the addition of 1.5～9wt%, M-phthalic acid-5-sulfonate is 0.9～3.7wt%; The inherent viscosity of the polymer that makes is between 0.5～0.65dl/g; This polyester fiber still satisfies the drafted fibre of following characteristic simultaneously:
A. filament number: 0.5～3.5dtex
B.
C. boiling water shrinkage≤15%.
Non-antimony-based catalyst is a Titanium series catalyst, and its general structure is as follows:
Wherein R1～R4 is the compound of following general formula:
R7～R9 is that hydrogen atom or carbon are 1～30 alkyl, ether, hydroxyl, carboxyl, carbonyl, ester group or amido in the formula.
The preferred polyethylene glycol of the poly-dihydric alcohol of combined polymerization composition.
The preferred 5-sodium sulfo isophthalate salt of the M-phthalic acid of combined polymerization composition-5-metal organic sulfonate, M-phthalic acid-5-sulfonic acid potassium salt or M-phthalic acid-5-sulfonic acid lithium salts.
The preferred PC-50 of the titanium catalyst that uses in the copolymerization process.
As the M-phthalic acid-5-metal organic sulfonate of combined polymerization composition, can be sodium salt, sylvite or lithium salts, and addition is 0.9～3.7wt% with respect to the fibre-forming polymer total amount, preferred 1.2～3.0wt%, most preferably 1.5～2.5wt%.When addition was lower than 0.9wt%, though its fiber that makes can have higher intensity, dyeability sharply descended, and can only dye to middle light color, can't reach desirable fresh colour, and light resistance also descends to some extent.And opposite, when addition is higher than 3.7wt%, its fiber that makes has good dyeability, but because the combined polymerization composition is too much, the intensity of fiber sharply descends, and have the ratio of amorphous area to increase, the COLOR FASTNESS after the dyeing also obviously descends, and it is more serious to fade.
The inherent viscosity that makes polymer between 0.5～0.65dl/g, preferred 0.55～0.65dl/g, 0.6～0.65dl/g most preferably, when inherent viscosity is lower than 0.5dl/g, the preparation difficulty; When inherent viscosity is higher than 0.65dl/g, use this high viscosity section melt spinning after, the fibre strength that makes is on the low side, and causes the later stage to use the fabric feeling of this fiber weaving hard partially, practical value is not obvious.
Owing to introduced sulfonic acid group in this polymer, sodium metal ion on it and the cation exchange in the cation dyes, dyestuff is fixed on the molecule of polyester by the effect of ionic bond, discharge salt simultaneously, so the dyeability of fiber is greatly improved, and polyethylene glycol and titanium catalyst have been added, when reaching the effect that normal pressure can dye, can reduce the pollution to environment again in a large number, be a kind of novel environmental protection polyester.
Novel normal pressure cation dyeable polyester fiber of the present invention can adopt any known melt spinning method, and the final finished fiber can adopt online single step spining drawing and forming, also can adopt two-step method, and promptly first spinning is extended processing again and made.
The spinning process of one-step method is as described below:
