Description
Technical field
The utility model belongs to technical field of textile machine, relates to a kind of minimizing Yarn filoplume nozzle, is applicable in the operations such as spinning, winder, can realizes reducing yam surface filoplume, improve yarn strength.
Background technology
Yarn filoplume refers to the fiber stretching out yam surface, mainly due to the motion not controlling fiber during spinning very well, makes the few fibers stretching out yarn surface be that circular arc or other shapes expose yarn surface.Yarn is subject to the effect of each friction means frictional force through winding procedure, causes imbedding not dark fiber and is out formed filoplume by withdrawing or the growth filoplume that rubbed by undercoat plumage.Winding procedure Yarn filoplume generally increases by 50% ~ 150%, even reaches 250%.Yarn filoplume affects yarn and final products outward appearance, feel and serviceability.In addition, in weaving process, filoplume is mutually pullled, is become entangled in, and causes loom opening unclear, affects weaving process and carry out smoothly.The raising required properties of textile along with people and novel high speed loom are to the bright and clean particular/special requirement of yam surface, and hairiness problems more and more causes the great attention of production firm and user.
Be conventionally used to the measure reducing filoplume to mainly contain: adjusting process parameter, as choose reasonable raw material, improve semi-products structure and fineness; Adjustment fine spining machine ingot speed, control bobbin winder speed etc.; Or adopt novel winder technology to reduce filoplume, as designed novel balloon breaker, adopt advanced tensioner.
Summary of the invention
The utility model designs one and reduces Yarn filoplume nozzle, be installed on automatic winder, under fumarole action of high-speed airflow, yarn rotates motion in yarn road, utilize " false twisting-backtwisting-looping " principle, reduce yam surface filoplume, improve yarn strength, be conducive to carrying out smoothly of later process.Subtracting plumage nozzle and also can being applied on fine spining machine of the utility model design, reduces Yarn filoplume in spinning process.
For achieving the above object, subtract plumage nozzle arrangements and comprise slit, yarn road, fumarole.Slot width calculates according to yarn diameter, grips yarn slip in yarn road for air splicer automatic knotting during automatic winder Yarn break; Yarn road is mainly used in yarn and rotates under action of high-speed airflow, according to " false twisting-backtwisting-looping " principle, around yam surface filoplume looping to body yarn; Fumarole is mainly used in providing high velocity air, its axis and yarn road circumference tangent.
As optimization, for adapting to bobbin winder automatic knotting needs, must design a slit, when broken end occurs yarn, air splicer automatic knotting yarn makes it to slip in yarn road.The width of nozzle slot depends on yarn diameter, and the too wide meeting of slit causes air-flow to spray from gap.For this reason, subtracting plumage nozzle slot width design is 0.4mm.
As optimization, nozzle yarn path diameter and yam count, yarn quality have close relationship, to the formation important of ballooning of yarn.When yarn path diameter is too small, air-flow in yarn road will be caused to clash into, affect air ring rotating speed, and then affect false twisting efficiency.In order in Shi Sha road, yarn forms stable air ring, reach the effect reducing filoplume, getting yarn path diameter is 4mm.
As optimization, the flowing of jet bore dia on air-flow has significant impact.Injection diameter is little, the flowing of meeting barrier air, and air force consumes low, weakens the stationarity of air-flow.Reduce injection diameter and need increase air pressure, the too small degree of purity to air-flow requires too high, improves the machining accuracy of spray orifice.Injection diameter increases, and in yarn road, air ring rotating speed improves, and is conducive to the twisting effect of nozzle.Can produce higher air ring rotating speed when fumarole diameter is 0.3mm, also not need too high air pressure, and air force consumes low.In addition, it is first apply the reverse backtwisting power of air-flow to loosen yarn that nozzle subtracts plumage mechanism, then utilizes positive draft false twisting power by ease for filoplume in yam surface or be involved in yarn body.For making full use of false twisting, backtwisting moment, requiring to improve air-flow component velocity tangentially, reducing air-flow component velocity vertically.Meanwhile, be improve the processing and manufacturing precision of part, reduce difficulty of processing, fumarole axis and yarn road tangent.
The flowing of injection diameter size on air-flow has significant impact.Injection diameter is little, the flowing of barrier air, weakens the stationarity of air-flow; Injection diameter increases, and in yarn road, air ring rotating speed improves, and is conducive to the twisting effect of nozzle.In order to both produce higher applicable air ring rotating speed, also do not need too high air pressure and air force consumption is also low, fumarole diameter design is 0.3mm.
Operation principle is: will subtract plumage nozzle and be installed on bobbin winder, and under fumarole action of high-speed airflow, yarn is High Rotation Speed in yarn road, utilize " false twisting-backtwisting-looping " principle, namely loosen under airflow function after yarn enters nozzle, when yarn leaves nozzle, yarn body is twisted with the fingers tight.Yarn texture is loosened and is twisted with the fingers in tight process, and filoplume is twisted in yarn body.Nozzle adopts three spray orifice designs, and if air-flow in fumarole in Fig. 24 and 5 is along counterclockwise rotation direction, effect makes the filoplume of yam surface form initial looping; In fumarole 1 air-flow along dextrorotation to, effect makes yarn generation backtwisting, and the rotation direction of its eddy current is contrary with eddy current rotation direction in fumarole 4 and 5, and strength of vortex is less than strength of vortex in fumarole 4 and 5, guarantee yam surface filoplume looping present in the same way the twist distribution.In yarn road, yarn is under the effect of air-flow, not only makees autobiography but also revolve round the sun, and realizes by yam surface filoplume looping around yarn body, realizes reducing resultant yarn filoplume, does not change over twist per unit.
After adopting technique scheme, the utility model nozzle can reduce Yarn filoplume, improves yarn strength, contributes to the processing of yarn later process.

Detailed description of the invention
As illustrated in fig. 1 and 2, subtract plumage nozzle arrangements and mainly comprise the slit, yarn road, spray orifice etc. that are applicable to needed for automatic winder air splicer automatic knotting.Subtracting plumage nozzle utilizes High Rotation Speed air-flow to carry out the filoplume on wrap yarn surface, and yarn twist and brute force do not decline.In Fig. 1,1 is slit, in winder process during Yarn break air splicer automatic knotting yarn slip into yarn road.3 is yarn path, during doff at action of high-speed airflow yarn under working in the rotary motion of yarn road.2 is left side fumarole, tangent with yarn road, and yam surface filoplume is under airflow function around looping to body yarn.In Fig. 2,1 for fumarole Isosorbide-5-Nitrae be fumarole 2,5 is fumarole 3.Pore 1 is right side fumarole, and pore 2 and 3 is left side fumarole, fumarole and yarn road tangent, guarantee that air-flow vertically blows to yarn.
Subtract plumage nozzle and be installed on automatic winder, under fumarole action of high-speed airflow, yarn is High Rotation Speed in yarn road, utilizes " false twisting-backtwisting-looping " principle, loosens after namely yarn enters nozzle under airflow function, and when yarn leaves nozzle, yarn body is twisted with the fingers tight.Such yarn texture is loosened and is twisted with the fingers in tight process, and filoplume is twisted in yarn body.Yarn filoplume can significantly reduce after subtracting the effect of plumage nozzle air current, and fiber strength usage factor and wear resistance are improved.Better adaptation aft-loaded airfoil, to the needs of yarn, increases the added value of final products.
