Abstract
The utility model discloses a kation dyeable modified terylene FDY (Fully Drawn Yarn) fine denier filament with a round cross section, and further discloses a spinneret plate for producing the kation dyeable modified terylene FDY fine denier filament. The spinneret plate comprises a spinneret plate body, wherein spinneret holes are formed on the spinneret plate body and include big holes and small holes; the diameters of the big holes are larger than those of the small holes; the cross sections of the spinneret holes are round; and the section of each spinneret hole in the thickness direction of the spinneret plate is Y-shaped. The utility model has the advantages that the dyeing depth, the vividness and the chromatophile of terylene are improved; the spinneret plate can spin tows with different diameters at the same time; relatively different traction multiples can be achieved on the same traction equipment, so as to obtain fibre tows with different sizes and different thermal shrinkage rates; and the sections of the spinneret holes are Y-shaped, which can improve the degree of orientation of fiber, increase the strength of the fiber and improve the quality of the tows.
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.
Summary of the invention
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.

The specific embodiment
Following examples are used to explain the utility model, are not used for limiting the utility model.
Shown in Fig. 1 to 3; The cation dyeable modified polyester FDY fine denier filament of the utility model, the cross sectional shape of cation dyeable modified polyester FDY fine denier filament are circular, and the specification of cation dyeable modified polyester FDY fine denier filament is 44dtex/24f; CATION engrain polyester filament can combine with ionic bond with cation dyes; Improve 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 above-mentioned cation dyeable modified polyester FDY fine denier filament production usefulness, it comprises spinnerets plate body 1, is distributed with a plurality of spinneret orifices 2 on the spinnerets plate body 1; Spinneret orifice 2 is made up of macropore 3 and aperture 4; The aperture of macropore 3 is greater than the aperture of aperture 4, and the cross section of spinneret orifice 2 is circular, and spinneret orifice 2 is being the Y type along the section on the spinnerets thickness direction; Macropore 3 is concentric circles with aperture 4 and is spaced distribution on spinnerets plate body 1; The aperture of macropore 3 and aperture 4 is than being 1.5:1, and the Y type angle in macropore 3 cross sections is 18 °, and the Y type angle γ in aperture 4 cross sections is 10 °.
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 2 is circular; Spinneret orifice 2 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.
