Abstract
The utility model discloses cationic dyeable modified polyester FDY fine denier filaments with circular sections. The utility model further discloses a spinneret plate for production of the cationic dyeable modified polyester FDY fine denier filaments. The spinneret plate comprises a spinneret plate body, a plurality of spinneret orifices composed of large orifices and small orifices are distributed on the spinneret plate body, apertures of the large orifices are larger than those of the small orifices, the sections of the spinneret orifices are in a circular shape, and sections of the spinneret orifices in the thickness direction of the spinneret plate are in a Y shape. The spinneret plate for production of the cationic dyeable modified polyester FDY fine denier filaments has the advantages that dyeing depth, brightness and chromophilia of polyester are improved; the spinneret plate can eject tows with different diameters simultaneously, relatively different traction multiples can be obtained from one traction device, and therefore fiber tows with different fineness and thermal shrinkage can be obtained; and sections of the spinneret orifices in the thickness direction of the spinneret plate are in the Y shape, so that degree of orientation of fibers can be improved, intensity of fibers can be enhanced, and quality of silks can be improved.
Description
Technical field
The utility model relates to cation dyeable modified polyester FDY fine denier filament.
The utility model also relates to the spinnerets of cation dyeable modified polyester FDY fine denier filament production usefulness.
Background technology
Do not contain hydrophilic radical on the big molecule of polyster fibre, only have the very little ester group of polarity, belong to hydrophobic fibre; The functional group that shortage can combine with direct dyes, ACID DYES, basic-dyeable fibre etc. can form the strong ester group of hydrogen with DISPERSE DYES though have, and the terylene molecular chain structure is tight; Dye molecule is difficult for getting into fibrous inside, causes the dyeing difficulty, and color and luster is dull; And must under HTHP or by carrier, dye, directly have influence on the exploitation of polyester fabric designs and varieties.Existing synthetic fiber form through the fibre bundle plying of different fiber numbers and different heat shrunk rates usually; In the fibre bundle production process; Because the aperture of the spinneret orifice on the spinnerets is identical, in order to obtain the fibre bundle of different fiber numbers and different heat shrunk rates, can only produce by technology separately through the draw-gear of different multiples and realize; So just make whole spinning process seem complicated, thereby increased production cost; Common in addition spinnerets is the circular hole spinnerets, and easy blocking, fiber orientation are poor, and fibre strength is low, can not satisfy normal production requirement.Therefore, need provide a kind of new technical scheme to solve above-mentioned technical problem.
The utility model content
The purpose of the utility model provides the cation dyeable modified polyester FDY fine denier filament that a kind of vividness is high, chromatophilia is good.
Another purpose of the utility model provides the spinnerets of the good glass cloth of a kind of difficult obstruction, fiber orientation with ultra-fine ultra soft polyester filament production usefulness.
The utility model solves the technical scheme that its technical problem adopted:
Cation dyeable modified polyester FDY fine denier filament, the cross sectional shape of said cation dyeable modified polyester FDY fine denier filament are circular.
The specification of said cation dyeable modified polyester FDY fine denier filament is 44-61dtex/24f.
The spinnerets of cation dyeable modified polyester FDY fine denier filament production usefulness; It comprises the spinnerets plate body; Be distributed with a plurality of spinneret orifices on the said spinnerets plate body, said spinneret orifice is made up of macropore and aperture, and the aperture of said macropore is greater than the aperture of aperture; The cross section of said spinneret orifice is circular, and said spinneret orifice is being the Y type along the section on the spinnerets thickness direction.
Said macropore and aperture are concentric circles and are spaced distribution on the spinnerets plate body.
The aperture of said macropore and aperture is than being 1.5-3:1.
The Y type angle in said macropore cross section is 15-20 °.
The Y type angle γ in said aperture cross section is 8-12 °.
The beneficial effect of the utility model is: CATION engrain polyester filament can combine with ionic bond with cation dyes, improves dye level, vividness and the chromatophilia of terylene, and its wet fastness and sublimation reliability are good; Can practice thrift dyestuff than ordinary polyester, the spinnerets of the utility model can spray the tow of different-diameter simultaneously, on same traction equipment, can obtain different relatively traction multiples; Thereby obtain the fibre bundle of different fiber numbers and different heat shrunk rates; The cross section of spinneret orifice is circular, and spinneret orifice is being the Y type along the section on the spinnerets thickness direction, can improve the fiber orientation degree; Increase the intensity of fiber, the quality of silk is improved.
