Abstract
The invention discloses novel cationic-dyeable polyester fiber. Polymers for forming the fiber are copolymers generated by terephthalic acid, 1,4-butanediol, a third polymerization monomer of m-phthalic acid-5-metal organic sulfonate and a fourth polymerization monomer of polyethyleneglycol.

Description
Technical field:
The present invention relates to a kind of novel cation dyeable dacron, specifically a kind of cationic-dyeable polybutylene terephthalate (PBT) fiber (is called for short: CDPBT).
Background technology:
The physical and mechanical property and the comprehensive wearing characteristics of polyester fiber are good, but because the tight packing of polyester molecule chain, the degree of crystallinity and the degree of orientation are higher, polarity is less, lacks hydrophily, the gap that does not have suitably to hold dye molecule between the long-chain molecule of polyester, therefore the dyestuff ion is difficult for penetrating fiber, its dyeability is poor, can use the kind of dyestuff few, and polyester fiber can only adopt methods such as DISPERSE DYES carrier dyeing, high-temp dyeing and pad-dry-cure dyeing.
Belong to the polytrimethylene terephthalate (Polytrimethyleneterephthalate of polyester fiber, be called for short: PTT) and polybutylene terephthalate (PBT) (PolybutyleneTerephthalate, PBT) fiber, not only has polyethylene terephthalate (PET, be commonly called as terylene) durability, DIMENSIONAL STABILITY, hygrometric state brute force, the soft feel and the anti-wear performance of polyamide fibre (PA), and stainability is better than terylene and polyamide fibre.Because the soft degree of its strand is much larger than polyethylene terephthalate (PET), so just can dye middle look under condition of normal pressure.But,, still can only adopt DISPERSE DYES, and its COLOR FASTNESS is lower because the structure of molecule is tight.
In order to improve the Color of polyester fiber, the researcher of the sector has carried out a lot of research, own diester-the 5-sodium sulfonate is as the combined polymerization composition just to propose to adopt M-phthalic acid as number of patent application 02110770.X, and modifying common PET polyester obtains a kind of fiber of cation dye chromophil.In addition, as number of patent application: 200510054950.3 and 200710144143.X mention, be to adopt the own diester of M-phthalic acid-5-sodium sulfonate equally as the combined polymerization composition, come the modified PTT polyester, thereby make the ptt fiber of cationic dye capable of dyeing.
Summary of the invention:
The purpose of this invention is to provide a kind of polybutylene terephthalate (PBT) (CD-PBT) fiber of cationic-dyeable, not only have the good dyeability of cationic dye capable of dyeing, also good simultaneously flexibility and elastic recovery.
The technology of the present invention solution is:
A kind of cationic-dyeable polybutylene terephthalate (PBT) fiber, the polymer of forming this fiber is a terephthalic acid (TPA), 1, the copolymer that 4-butanediol and trimerization monomer M-phthalic acid-5-metal organic sulfonate and the 4th polymerization single polymerization monomer polyethylene glycol generate.
As the M-phthalic acid-5-metal organic sulfonate of trimerization monomer, can be sodium salt, sylvite or lithium salts, and addition is 1～10wt% of co-polymer total amount, preferred 3～6wt%, most preferably 4～5wt%.When addition was lower than 1wt%, 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 10wt%, 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.
As the polyethylene glycol of the 4th monomer, its molecular weight is 500～2000, and is preferred 700～1500, most preferably 900～1200, and its addition is the 1wt% of polymer total amount.As the 4th monomer PEG of combined polymerization composition, its molecular weight and addition all affect the characteristic of fiber, and molecular weight is big more, addition is many more, its fiber intensity all bigger decline can be arranged, particularly when molecular weight 2000 when above, it is more obvious that its influence becomes.And the addition aspect, the present invention directly adopts lower value 1wt%, to guarantee fiber good intensity and good light resistance is arranged.Because when addition increases gradually, we find that the intensity of fiber and light resistance also obviously descend thereupon.
The inherent viscosity of the polymer that makes by above-mentioned prescription is comparatively suitable in 0.8～1.2dl/g scope, preferred 0.9～1.1dl/g.When the inherent viscosity of polymer was lower than 0.8dl/g, fiber can embody the ill effect of low-intensity, low elasticity, simultaneously, when the inherent viscosity of polymer is higher than 1.2dl/g, since the excessive problem of viscosity, the mobile variation of polymer, the spinnability of fiber obviously descends, and is unfavorable for mass production.
Cationic-dyeable polybutylene terephthalate (PBT) fiber of the present invention, its physical characteristic satisfies following characteristic:
A.
B. boiling water shrinkage≤10%
C. return rate 〉=40% of crispaturaing
D. flexible percentage elongation 〉=170%
Cationic-dyeable polybutylene terephthalate (PBT) fiber of the present invention can adopt any known melt spinning method, and the final finished fiber can the employing two-step method, promptly first spinning, and reprocessing makes.
With above-mentioned polyester slice at the drying machine inner drying to moisture 100ppm, and input feed bin, enter screw rod fusion under 250～300 ℃ of temperature through feed bin, control its discharge-amount by measuring pump, by by the filament spinning component of spinning manifold control temperature under 250～300 ℃ of conditions, spin as-spun fibre, cooling curing moulding under lateral blowing wind speed 15～40m/min condition, make the collection of filaments and reduce friction through to oil nozzle fiber evenly being oiled again, oil addition is 0.5～1.5%.
The fiber that the oil supply boundling is over passes spinning shaft, through pre-winding apparatus interlacing, enter first roller (1GR), pass main winding apparatus, batch and make preorientation fiber (POY) through enter coiling machine behind second roller (2GR) again, the coiling speed of coiling machine is 1200～3500m/min.
Gained POY can make false twisting machining deformation silk respectively and extend silk by following two kinds of methods.
1, the POY that makes is carried out false twisting and be processed into false twist textured yarn (DTY): the pre-oriented yarn that above-mentioned steps gets is processed on false twisting machine, process velocity is that 300～700m/min, first heater temperature are that 130～220 ℃, second heater temperature are that 110～200 ℃, extension ratio are to carry out false twisting processing under 1.20～3.00 the condition, makes the machining deformation silk.
2, the POY that makes is extended be processed into and extend silk (DT): the pre-oriented yarn that above-mentioned steps gets is processed on elongator, process velocity is that 300～700m/min, first heat roller temperature are that 130～220 ℃, second heat roller temperature are that 110～200 ℃, extension ratio are to extend processing under 1.20～3.00 the condition, makes and extends silk.
Cationic-dyeable polybutylene terephthalate (PBT) fiber of the present invention has possessed in cation dyes and has dyeed, and can obtain bright in lusterly, and the dyeing property of function admirable has also possessed the superior elasticity that elastomer had and replied effect.Simultaneously, because the price of PBT polyester raw material is compared advantage that increasing also arranged in PTT far below the PTT polyester raw material from the cost aspect.
In order to verify effective effect of the present invention, the above-mentioned fiber (DTY, DT) that makes is carried out tube compile processing, make tube and compile thing.Tube is compiled thing, and to put into concentration be that 1% and 3% dye liquor dyes, and with dying the light evaluation of carrying out fast light fastness and washing fastness with the sample of engrain respectively of dying, can obtain 4 grades of fast light fastness, the result of washing fastness more than 4 grades.
