Description
Technical field
The invention belongs to textile development fields, and in particular to a kind of aromatic polyester-aliphatic polyester blocked copolyester
Fiber and purposes.
Background technique
Polyester fiber has many advantages, such as good breaking strength height, form stable, stiffness, wash and wear, easy to wash easily dry, is one
The more satisfactory textile fabric of kind.It is regular that these excellent physical and mechanical properties of polyester fiber depend on its High level of stereoselectivity
The condensed state structure of macromolecular chain structure and high-crystallinity and the degree of orientation, but these architectural characteristics also give polyester fiber
Achromatic defect.Meanwhile the lesser ester group of polarized in polyester fiber molecular structure, shortage can be bonded with dyestuff
The active group of effect can only be dyed using disperse dyes.Disperse dyes belong to nonionic dye, molecular dimension compared with
Greatly, water-soluble lower, while the water imbibition of polyester fiber is poor, is not easy to expand in water, so when being dyed with conventional method, dye
The dispersion particle of material is difficult to enter fiber from solution, very low the dye-uptake under fluidized state.Polyester in the prior art
The dyeing of fiber generallys use high-temperature and high pressure dyeing process and carrier boiling dyeing at normal pressure method.When polyester fiber is dyed using support methods, by
Internal plasticization can be played in fibrous inside in carrier, is conducive to dyestuff in the diffusion of fibrous inside, but remaining carrier can make
The light resistance of dyestuff is deteriorated, and pollutes.Under the pressure of environmental protection pressure, carrier dyeing process is gradually backed out the arena of history, high temperature and pressure
Decoration method has become mainstream.But that there are energy consumptions is high for high-temperature and high pressure dyeing process, is difficult to the shortcomings that serialization industrial production, and be difficult to
The elastomers co-bathing dyeing such as the natural fibers such as cotton, wool, the silk of non-refractory and spandex, this strongly limits polyester
The application range of fiber.
Therefore, the research and development of the dyeable modified polyester fiber of normal pressure are always by the extensive concern of academia and industry.
Currently, the preparation of the dyeable modified polyester fiber of normal pressure mainly changes polyester fiber by the method for physical modification or chemical modification
Molecular structure or supramolecular structure, introduce dye molecule receive base or increase accommodate dye molecule space, thus realize change
The normal pressure of property polyester fiber can contaminate.
ZL02111210.X discloses a kind of dyed easily by disperse dye functionality copolyester fiber and preparation method, the patent
Dyed easily by disperse dye functionality copolyester section using terephthalic acid (TPA), ethylene glycol as raw material, it is (opposite that 2-100mol% is added
In terephthalic acid (TPA)) the Third monomer of the binary acid containing isophthalic be copolymerized.Between being added on polyester macromolecule
The Third monomer of phenyl group, so that the regularity of polyester macromolecule declines, crystallizing power weakens, and amorphous area increases, short texture,
There is disperse dye normal pressure stainability using the fiber that copolyester section spins.But since dyed easily by disperse dye functionality is total
Polyester is random copolymer, and molecular structure regularity is poor, crystallizing power is weaker, and fiber size stability is poor, in boiling water condition
It is lower easily to occur largely to shrink, it is difficult to be widely used in garment industry.
CN201110366748.X discloses a kind of normal pressure disperse dye dyeable modified copolymer ester fiber, by modified copolyester
Spinning forms, in copolyesters containing Third monomer be band side chain and carbon atom number be 6 aliphatic dihydroxy alcohols below.Due to polyester
Introducing with side chain dihydric alcohol structural unit in molecular backbone, so that the regularity of macromolecular declines, crystallizing power weakens, amorphous
Area increases, short texture, so that the performance that copolyester fiber disperse dye normal pressure can contaminate is imparted, but the fiber of the copolyesters
Dimensional stability is also poor, and the shortcomings that largely shrinking easily occurs under the conditions of boiling water.
In order to solve defect in the prior art, the present invention is specifically proposed.
