Description

A kind of Fancy Yarns and spinning method for genuine thereof
Technical field
The invention belongs to spinninging technical field, relate to a kind of Fancy Yarns and spinning method for genuine thereof, particularly relate to a kind of utilize a kind of filament stream from enter revolving cup to and to close on the path before cohesion and on certain length, to apply continuously the Revolving cup spinning Fancy Yarns of method spun yarn line density in longitudinally change of external force.
Background technology
Revolving cup spinning belongs to open-end-spinning field, has the advantages that spinning speed is high, package capacity is large, spin ability is better and doublely can spin excellent low raw material, has become the spinning form that technology in Advanced Spinning Technologies is the most ripe, application surface is the widest, economy is higher.
Revolving cup spinning only uses the raw material of low cost at first, the leftover bits and pieces of such as textile mills or recycling textile material etc.In 20 century 70 mid-terms, Revolving cup spinning is only applied to and spins cotton product, and mainly to spin 97.2tex (6 s), 83.3tex (7 s) Quality Pure Cotton Yarn Production is main, therefore industry generally believes that Revolving cup spinning is only suitable for thick special Quality Pure Cotton Yarn Production at that time.But along with the progress of Revolving cup spinning technology, the spinning suiting scope of Revolving cup spinning is also increasing gradually.Nowadays, Revolving cup spinning not only may be used for the production of high-grade knitted yarn, also can be applicable to undertwisted yarn, slub yarn, S twist yarn, the many Fancy Yarnss of cladded yarn.
Utilize Revolving cup spinning to produce the Fancy Yarns kinds such as slub yarn and there is multiple method, substantially can have following several scheme: (1) changes feed roller speed; (2) delivery roller speed is changed; (3) change feed roller and delivery roller speed simultaneously; (4) additional feeding fiber mechanism is added in the appropriate location of defeated fine passage or combing roller; (5) damping point is set in revolving cup; (6) cutting in revolving cup; (7) transformation of navel.
Utilize the method changing feed roller speed or delivery roller speed, the shortest Fancy Yarns that can spin a revolving cup perimeter length slubbing, and the length of slubbing and diameter are subject to the impact of revolving cup diameter and motor performance larger; The method arranging damping point in revolving cup in revolving cup, arranges 1 or several damping point in fibre deposition groove to spin Fancy Yarns, although adopt the method can spin out the shorter Fancy Yarns of thickness joint, but fibre deposition groove is the easy dust stratification in damping point both sides particularly, make the thickness joint of Fancy Yarns unstable; In revolving cup, the method for cutting is that artificially processes groove on fiber slippage face, makes it have certain degree of depth and length, but this method can make to produce dust stratification in groove equally, affects the stability of Fancy Yarns.
Summary of the invention
Problem to be solved by this invention is to provide a kind of Fancy Yarns and spinning method for genuine thereof, specifically a kind of utilize a kind of filament stream from enter revolving cup to and to close on the path before cohesion and on certain length, to apply continuously the Revolving cup spinning Fancy Yarns of method spun yarn line density in longitudinally change of external force.
A kind of Fancy Yarns of the present invention is super imitative cotton/viscose blended yarn, comprise base yarn and the first slubbing, described Fancy Yarns 1 vertical line density is rule change in the fragment of a revolving cup girth, wherein half revolving cup girth there is at least 1 section of first slubbing, there is 1 section of length and all little second slubbing of diameter compared with described first slubbing in second half revolving cup girth, described first slubbing and the second slubbing is more fluffy than described base yarn yarn body and the twist is little; The fineness of described base yarn is 25 ~ 120tex, and the distance between the first slubbing and the second slubbing is minimum is 5mm, is 1/2 revolving cup girth to the maximum; In a described semi-circumference, between two section of first slubbing, the length of base yarn is with the distance change between two narrow slits, and scope is at 3mm ~ 85mm; The length of described first slubbing is 10 ~ 20mm, and maximum gauge is 0.35 ~ 0.6mm; The length of described second slubbing is 10 ~ 12mm, and maximum gauge is 0.15 ~ 0.3mm.
The present invention also proposes the spinning method for genuine of Fancy Yarns described in more than one, comprises following technical scheme:
The spinning method for genuine of a kind of Fancy Yarns of the present invention, the spinning method for genuine of described Fancy Yarns is Revolving cup spinning, the filament stream of Revolving cup spinning is to enter on revolving cup to the path merged before cohesion and apply external force continuously on certain length, the direction of described external force becomes 0 ~ 15 ° of angle with the axial line of rotor axis, described revolving cup comprises cup and cup axle, cup is made up of at the bottom of cup and cup edge, cup forms collection surface along crossing with at the bottom of cup, described certain length applies continuously external force and refer to that at the bottom of described cup, bottom surface divides equally 2 half, wherein half is arranged at least 1 group narrow slit, often organize narrow slit and have 2-3 bar narrow slit, the groove that 1 is depressed in described fiber slippage face is carved with in fiber slippage face corresponding at the bottom of another half cup, described narrow slit place imposes malleation or or the additional air-flow of negative pressure.
As preferred technical scheme:
The spinning method for genuine of a kind of Fancy Yarns as above, at the bottom of the through described cup of described narrow slit, the distance of described narrow slit near the distance Bei Di center, one end at Bei Di center is 5 ~ 15mm, and described narrow slit is arcuate midway point 5 ~ 12mm at the bottom of the distance collection surface of collection surface one end; Described groove, along revolving cup circumferencial direction, is 0 ~ 30 with the angle of described fiber slippage face top border 0.
The spinning method for genuine of a kind of Fancy Yarns as above, the mode of described applying external force refers to that the pressure malleation of described additional air-flow be 1000 ~ 4000Pa or negative pressure is-1000 ~-4000Pa.When the pressure of additional air-flow is larger, more fiber can be made to be entered in revolving cup cavity by narrow slit, cause the loss of fiber; When the pressure of additional air-flow is less, the buildup effects of fiber in narrow slit can be affected, make the slubbing DeGrain of generation.
The spinning method for genuine of a kind of Fancy Yarns as above, the diametric(al) of described narrow slit and described cup is the angle of 0 ~ 60 °, described narrow slit is the continuous straight narrow slit of rectangle, trapezoidal continuous straight narrow slit, wide bending narrow slit or not wide bending narrow slit, the discontinuous straight narrow slit of rectangle, the width of the continuous straight narrow slit of described rectangle is 2.5 ~ 4.5mm, the width of described wide bending narrow slit is 2.5 ~ 4.5mm, the width at the described trapezoidal continuous straight the narrowest place of narrow slit is 1.5 ~ 2.5mm, the width of the widest part is 3 ~ 4.5mm, the width at the narrowest place of described not wide bending narrow slit is 1.5 ~ 2.5mm, the width of the widest part is 3 ~ 4.5mm, the discontinuous straight narrow slit of described rectangle comprises two narrow slits in a straight line, and the spacing distance of these two narrow slits is 0.5 ~ 1.5mm.The effect of such design is, when the overall width of described narrow slit is too small, can affects fiber gathering at narrow slit place, affect spinning effect, and when described slit width is too large, fiber can be entered in revolving cup cavity by narrow slit, causes loss and the waste of raw material.
