Description
The invention relates to the production of rove, intermediate products just from initial ribbon to the yarn that finally is spun into, more particularly, rove is generally considered to be preceding one product of the yarn that has spun.In other words, rove is fibrous raw material or the sliver that has passed through drafting, drawing-off and twisting usually, and this twisting is for later process, split as ring and spin, and the preparation of doing, especially for producing yarn.
Be familiar with the people of the rove operation in the spinning, know that all tradition spins in the technology of rove, have a lot of problems.For example, the rove device of traditional employing flier (sth. made by twisting that has added 0.5 to 1.5 turn on fiber) has many complicated mechanical parts and structure, has brought the problem of aspects such as downtime and maintenance; Because the use of flier, the speed of this Speed frames reduces, and because the twisting count in the reality changes, has produced draw problems again in spun yarn.Also run into difficulty in addition on creeling and doffing operation, production process is difficult to realize automation.
In traditional employing rubbing method (rub roving) rove device, ribbon is sandwiched between two aprons, and two aprons move around round about, and ribbon is rolled therein, because fiber is twisted and interconnected, intensity increases.Yet in the rove device of rubbing, still there is unfavorable factor.For example, though reach high speed and resultant effect, it still has complicated mechanism, and operation is expensive.In addition, this technology has been aggravated unsettled drawing-off, and is special in the raw material that dyed look, thereby cause the inequality of yarn when spinning.This also is because apron is incoherent on the whole length on rove surface, thereby causes the variation of drafting force.
The present invention has adopted a very simple mechanical device, and the rove of production was both untrue to be twisted with the fingers, and does not also have false twisting, and it has fundamentally overcome above-mentioned shortcoming and defect.This new process application known vacuum spinning technique, consequently, for back road spinning process provides high-quality rove.
Illustrate that with regard to the present invention in textile industry, vacuum is spun and is not a new technology.But up to the present, it only is used in spun yarn and produces, as, the method and apparatus in the United States Patent (USP) of generally having transferred the possession of 4,719,744,4,713,931 and 4,507,913 all is to describe vacuum spinning.At United States Patent (USP) 4,635, the method and apparatus in 435 then is the vacuum spinning of describing directly from ribbon.
In the present invention, vacuum is spun and is applied to both not having true sth. made by twisting, does not have again in the rove production of false twisting.And process of roving of the present invention, eliminated many problems that in the process of roving of traditional flier and rubbing, exist.The thick bar that goes out with this explained hereafter qualitatively at least with obtain from these traditional handicrafts identical.
In one embodiment of the invention, promptly ribbon is involved in the bar tube by common drawing frame.Ribbon can be made up of long fiber or staple fibre, and promptly fiber is about 1 inch to 6 inches, and then, it is fed common drafter from the bar tube, just, and the identical drafter used with the process of roving of traditional flier and rubbing formula.When the strip of drawing-off, pass the first break draft roller, when entering the roller draw zone, it will be subjected to drawing-off through the vacuum nozzle device time.This spray nozzle device is described below.
Fiber on the ribbon is pushed, hauls, and enters an import in quill shaft, perhaps is installed in the nozzle free to rotate on the housing.At this moment, fiber is subjected to the double action of feeding roller and the vacuum that produces (can by any suitable manner form) in nozzle.When fiber passes nozzle, in the free end of surface fiber sub-fraction is arranged, on the direction of advancing with respect to fibre bundle is radially outside direction, is inhaled into and is distributed in the yarn sucting port of going up on every side.When fibre bundle continues when straight line moves, the fiber ends of scattering radially is drawn out yarn sucting port immediately, by the rotation of nozzle, is wrapped on the fibre core that is retained on the center.This wrapper fibre preferably accounts for 5% to 20% of fiber.Experiment shows that nearly 10% wrapper fibre is tending towards stretching when the spinning, drawing in road, back.
The quantity of wrapped yarn can be by nozzle rotating speed, nozzle in the quantity and the size of yarn sucting port, and control such as vacuum pressure.Because have the quantity of the wrapper fibre of this control on the fibre core and twine the ability of fastness, so can produce the rove of good characteristic.
Rove is batched by winding roller, and with the high speed similar to common doffer, around to flyer bobbin.Winding speed is between 100 to 150 yards/minute (91-136 rice/minute), and these flyer bobbins can be hung on the bobbin shelf of ring throstle, is used for the bobbin cradle spinning of single or double type, and the number scope of yarn can be very wide like this.
According to process of roving of the present invention, be very flexibly for the fineness of rove.And experiment shows, if the ratio of wrapper fibre remains on 15% or still less, these fibers then under high pressure do not twine, its quality is identical with roving yarn quality with the process of roving production of flier or rubbing.
The automation that technology of the present invention is suitable for producing, this automation is similar to the rove of use apron rubbing at present, but the rubbing method is only limited to long fiber (can not be used for staple fibre production).The present invention is suitable for for long fiber and staple fibre.
As known vacuum spinning process, another advantage of the present invention is that the suction at nozzle place can be removed a large amount of impurity, as smoits, dust and dust etc., raw material is more cleaned.
Thereby this new rove is made notion, compared with the method and the technology of now general production rove more superiority is arranged.
Following will the description, when known vacuum spinning technique is used to produce rove, structure of nozzle with produce the identical of spun yarn, different is, the passage of the nozzle that rove is used the and radially diameter of yarn sucting port is bigger, with adapt to than spun yarn thick the rove of Duoing.In addition, drafter also must strengthen, and structure is more solid.
Can see that in broad terms, the present invention relates to the method for producing rove with a kind of, it is characterized in that, comprises following steps:
(a) the drawn fiber bar is to form the ribbon of drawing-off;
(b) ribbon of drawing-off feeds the vacuum nozzle that is rotating, makes to have sub-fraction in the fiber at least, is wound on the remaining fibre core, forms rove;
(c) described thick bar is wound up on the flyer bobbin.
Perhaps carry out as follows, promptly
(a) ribbon is fed draw zone from the ribbon storing place;
(b) when ribbon passes through described draw zone, the ribbon drawing-off is become predetermined weight;
(c) will be the ribbon of drawing-off, send into quill shaft along rectilinear direction, this is usually around the axis rotation consistent with above-mentioned rectilinear direction, and this has many yarn sucting ports that extend radially outward in the quill shaft;
(d) vacuumize by yarn sucting port, make its vacuum enough attract sub-fraction free end in the fiber in described yarn sucting port, and the major part in the fiber is still stayed in the quill shaft;
(e) when the fiber of described drawing-off passes through axle, rotate described axle, make the described small part free end in the fiber, therefore be wound on the major part in the described fiber, to form rove;
(f) and then after the step (e), reeling roving is being batched on the bobbin.
Through following detailed description, other purpose of the present invention and superiority can be very clear.
