Fig. 1: high-strength crease-shedding pearl fibre yarn spinning method process diagram
Five, the specific embodiment:
Embodiment one: the spinning method of high-strength crease-shedding pearl fibre yarn of the present invention, at first adopt scutching cotton equipment (griping cotton machine, cotton blender machine, opener, cotton feeder and lapper) with the pearl fiber shredding, make lap behind the removal of contamination, through carding machine pearl fiber is carried out combing then, further make the carded sliver behind the removal of contamination, make ripe after adopting drawing frame that the carded sliver is mixed again, with Speed frames rove is made in ripe draw twisting then, its unlike the prior art be: lower in order to overcome the pearl fiber brute force, the defective that shape-retaining ability is relatively poor, improve the brute force and the rigidity of pearl fibre yarn effectively, to improve the shape-retaining ability of pearl fiber fabric, make fabric be easy to arrange, reach the purpose of wash and wear, with the pearl fiber rove when the further draw twisting of fine spining machine becomes the pearl fiber spun yarn, incorporate the skeleton silk into and make the core silk, produce the high-strength crease-shedding pearl fibre yarn of making outer wrapping fiber with pearl fiber.Its production technology schematic diagram is seen Fig. 1.
1 is skeleton silk silk tube among Fig. 1, and 7 is the skeleton silk, and 2 is tension regulator, and 3 are the rotation godet roller, and 4 is fine spining machine, and 5 is flyer bobbin, and 8 is pearl fiber rove yarn, and 6 is the fine spining machine roller, and 9 is the high-strength crease-shedding pearl fibre yarn of producing.Producing high-strength crease-shedding pearl fibre yarn at first is to select the skeleton silk: by multiple polyester filament performance is compared, the final selected use 1F terylene skeleton silk that strand is smooth, intensity is high, bending resistance is strong is made the core silk, as the skeleton silk of core silk, also can select CATION terylene silk, POLYAMIDE YARNS or PTT long filament for use.Present embodiment selects for use 1F polyester FDY skeleton silk to make the core silk, and pearl fiber is made outer wrapping fiber and produced high-strength crease-shedding pearl fibre yarn.
The 1F polyester FDY skeleton silk package of domestic terylene manufacturer production all is the cone drums tube, more than the long 500mm of bobbin, diameter is about 150mm, a general silk tube weight is about 3kg, when coated yarn spinning, each spindle of spun yarn is wanted corresponding long filament bobbin, and it is very big that more than 400 silks tin are all put on the fine spining machine difficulty.Through contrast, we finally select a kind of fairly simple feasible frame remodeling method, make the long filament bobbin evenly be placed in the creel top, and block lathe work operation is convenient.
Polyester filament adopts passive unwinding mode in spinning process.Because the polyester FDY strand is very smooth, adhesive force extreme difference between silk and the silk, the easy knocking over of long filament causes unwinding tension suddenly big or suddenly small in passive unwinding process, extremely difficult control.In order to reduce the tension fluctuation that knocking over causes, in spinning process, long filament (skeleton silk 7) lead-out mode changed into along the tangential direction of skeleton silk silk tube 1 cylindrical pull out, and make long filament enter the tension adjustment district through tension regulator 2, incorporate the spun yarn yarn of having finished drawing-off on the fine spining machine after the adjustment of tonicity into.Tension regulator 2 can be controlled the size of skeleton silk 7 strand tension force.The too small influence of tension force coats quality, the overtension long filament is prone to the phenomenon of making a pause when entering front roller, and the short fiber yarn is to export from front roller with constant speed, pauses moment at long filament, the short fiber yarn will flexing, causes the sliver surface to form the fault of similar " cotton knot ".So tension regulator tension force size should be moderate, tension force should evenly could guarantee yarn quality between ingot and the ingot.By suitable adjustment tensioner tension force, can guarantee that the long filament unwinding is smooth and easy, tension force is moderate.
For guaranteeing the covered effect of high-strength crease-shedding pearl fibre yarn, we install rotation godet roller 3 additional above the front leather roller of fine spining machine 4.The covered effect of cladded yarn is very big to yarn quality, back working procedure processing difficulty, finished product appearance effects.The yarn defect that influences covered effect mainly contains bad yarn, hollow yarn and the three kinds of situations of naked silk of coating.The bad outsourcing short fiber that just is meant of so-called coating does not evenly envelope the core silk, and the core silk exposes sliver surface (being commonly called as inclined to one side silk) intermittently.We cut off the rove traversing gear in order to solve the bad problem of coating, make rove yarn outgoing position substantially constant, make the filament mouth position of rotation godet roller 3 should aim at drawing-off yarn middle part, core Si Kelve took back when spinning Z twisted with the fingers cladded yarn, and core Si Kelve took over when spinning S twisted with the fingers cladded yarn.So just can guarantee to fix after rotation godet roller position mixes up, in order to avoid walk about.By contrast test, wash long filament feeding front leather roller under certain tension force and can make the short fiber coating comparatively firm.As for hollow yarn defect and naked gauze defect, mainly be because rove or long filament broken end is not in time found, cause the lacuna feeding and form.Can only when operating, strengthen going the rounds by the spinner, check that conscientiously pinpointing the problems in time solves.Roving yarn quality should improve as far as possible in card room simultaneously, reduces the rove broken end.The spun yarn spinner should handle with care in putting long filament bobbin process, does not make long filament outer and end face scratch or knocking over.
Regular roving feeding also has certain influence to covered effect in addition.Because rove is ellipse rather than circle through its cross section after the package.The rove bar constantly overturns when entering the spinning-drafting district, its oval cross section constantly changes angle, this just causes the fiber strip that enters front roller can not keep the relative position of constant fabric width, yarn and core silk also continuous variation can take place, and must influence covered effect.In order to improve this phenomenon, we have done contrast test to the relation of regular roving feeding and covered effect.Test finds that regular roving feeding kicks the beam, and its drawing-off yarn fabric width and relative position change just obvious more, and slightly heavy its drawing-off yarn fabric width of regular roving feeding and relative position just change steadily.Reach a conclusion through yarn quality is tested us: regular roving feeding has certain influence to cladded yarn bar evenness, covered effect, and regular roving feeding should suit, and should not kick the beam.
The selection of outer wrapping fiber and core silk content: spinning method of the present invention, satisfying the requirement of fabric shape-retaining ability and guaranteeing that long filament can be coated under the exposed prerequisite in sliver center fully, be 20～25% of outsourcing pearl fibre yarn as its content of skeleton silk of core silk; Experimental result proves that core silk content effect between 20～25% is better.Present embodiment core silk content is chosen as 25%.
The spun yarn twist factor is selected: in the spinning method of the present invention, the twist factor of high-strength crease-shedding pearl fibre yarn is chosen to be between 300～480.According to the relation of twist factor and yarn strength, according to twist factor commonly used, the brute force of high-strength crease-shedding pearl fibre yarn is greater than the brute force of staple fibre yarn.If continue to improve twist factor, cladded yarn is powerful to be changed not quite.So the brute force and the twist factor relation of high-strength crease-shedding pearl fibre yarn are little in certain twist factor excursion.So we are when considering that twist factor is selected, the ABRASION RESISTANCE of improving yarn with avoid resultant yarn two factors of twisting together to put in the first place, twist factor to the influence of yarn strength for reference only.
Because skeleton silk smoother, single thread is in back operation and parts friction process, and the outsourcing short fiber easily peels off and causes naked gauze defect.Improve the cladded yarn twist factor and can make short fiber and the tight obvolvent of core silk, favourable to the ABRASION RESISTANCE of improving cladded yarn.But terylene skeleton silk has stronger resistance to torsion, if the twist is bigger than normal, resultant yarn is just twisted together easily in the working procedure processing process of back and formed handle.So the high-strength crease-shedding pearl fibre yarn twist factor is answered careful selection.Take into account the each side factor, the twist factor of present embodiment high-strength crease-shedding pearl fibre yarn is chosen to be 350.
Because of terylene skeleton silk easily adsorbs aerial tiny flyings in the unwinding process, the skeleton silk feeds tiny flyings from front leather roller and just accumulates between front leather roller and the jaw, gathers to a certain degree to bring into to form little slubbing in the sliver.In order to reduce this type of slubbing, can suitably amplify the front draft zone roller gauge.According to the pearl fiber characteristics, suitably strengthen back zone drafting multiple and improve bar evenness.Roller type selecting aspect is finally selected 2065 rollers spinning high-strength crease-shedding pearl fibre yarn for use by contrast test.
Embodiment two: referring to Fig. 1, and the present embodiment spinning method, different with embodiment one is: the skeleton silk as the core silk is selected the PTT long filament, and core silk content is chosen as 20%.The twist factor of the high-strength crease-shedding pearl fibre yarn of skeleton silk, pearl fibre yarn formation is chosen to be 300 in addition.
Embodiment three: referring to Fig. 1, and the present embodiment spinning method, different with embodiment one is: the skeleton silk as the core silk is selected polyamide fibre, and core silk content is chosen as 22.5%.The twist factor of the high-strength crease-shedding pearl fibre yarn that skeleton silk, pearl fibre yarn form is chosen to be 450.
