Abstract
What the present invention relates to is with friction spinning apparatus production method of yarn and equipment.Friction spinning apparatus is a perforation spinning drum barrel, protrudes a fiber feeding passage towards this drum barrel.A shredding roller is towards the separated fiber of feeding passage feeding, and this fiber is by carrying air flow to suck fiber feeding passage.This carries air flow to be produced by the friction spun yarn roller of perforation, and this roller bears negative pressure.The fiber that leaves fiber feeding access portal is placed on the friction spun yarn drum barrel, and becomes obliquity with it, and is carried towards the yarn ends that forms at yarn shaping position place on this position.Second friction spun yarn drum barrel installed becomes to be parallel to the first friction spun yarn drum barrel.
Description
What the present invention relates to is that a kind of friction spinning method and equipment are produced yarn or similar articles.
If, in friction spun yarn, ribbon being divided into single fiber by means of the shredding roller of similar use in rotor, those fibers are fed into friction spinning apparatus by means of a passage, and so nondirectional fiber just appears in this passage; At least some fibers lead to this access portal with the non-rectilinear state.But this nondirectional non-rectilinear fiber is the structure that is unfavorable for orderly yarn, or the fiber production low intensive relatively and underproof yarn of circle is arranged.
For example, by swiss patent specification 572108 disclosed a kind of devices, wherein, free-moving fiber is fed two with within the constringency cleft between the suction roller of kindred circumstances rotation; Fiber is twisted into yarn by the rotation of roller, and drafted by means of the drawing rollers of device on the roller end face.
Clearly those fibers that move freely must pass through pressure channel, and a final velocity arranged correspondingly, this speed is approximately big 10 times than the hauling speed of yarn, so just can make the fiber that arrives in the constringency cleft be braked to low like this speed, causing fiber to be wound in round when arriving, and these circles remain among the smart yarn.
Fibrous loop in the yarn has reduced yarn strength, and an irregular characteristic source is provided, and produces the non-directional fiber owing to arrive a large amount of ring-shaped fibers simultaneously.In addition, such ring-shaped fiber has shortened the length of useful fiber.The round that " round " of term fiber refers to by forming has shortened above-mentioned useful length.
To a certain extent, because the resistance that exists in the contraction at interval of drum barrel is produced yarn by the drawing-off of yarn and extends the extension that so also produces single fiber.And the characteristic of this yarn can not with those as the smart yarn of ring ingot relatively, therefore, this spinning form only is suitable for rove, has the reasonable distribution of single weakness, term " rove " refers to and is mainly used to produce decorative material.
About new spinning method, for example friction spun yarn is tried hard to produce and is weaved industrial yarn, owing to account for 60% of whole yarn production with yarn in this respect.
For fear of above-mentioned round, in other words for fiber being fed into yarn ends with open mode, German patent specification (offenlegunsschrift) No3300636 has designed a kind of friction open end spinning apparatus, have two identical driven rollers, arranging adjacent to each other, and the formation wedge gap, this place has a roller at least as air-breathing roller.One the feeding passage open on this air-breathing roller, and be disposed in air-breathing roller with respect on the wedge gap excircle direction.The limit portion of the guiding feeding passage of opening towards wedge gap in addition, is made into as the guide plate that turns to that transmits fiber.
Such shaping is turning to the guide plate place to be braked in order to guarantee fiber, by means of air-breathing roller drawing of fiber is gone out to feed passage simultaneously, and bears machinery and extend.The effect that this machinery extends is in order to cause improving falling of fiber.
But the shortcoming of this device is: fiber bears friction on the one hand, does not have this friction just can not obtain extending, and the harm of making dirty is being born on so on the other hand friction limit, therefore, collect the foul heap of depositing once in a while and, and can produce irregular yarn by the fiber band that passes through.
Therefore, the present invention is in order to produce a kind of method and apparatus, and wherein the yarn by friction spinning apparatus production comprises the directional fiber that process is improved.Another object of the present invention be fiber before being attached to yarn ends, they are taken in the position of air-breathing drum barrel, this air-breathing drum barrel be convenient to aduncate.
These purposes of the present invention are to reach by following measure: the fiber that is transferred on the friction spinning apparatus moving surface is transported to the yarn shaping position, when when the lead of yarn is looked, in fact place on this surface with straight configuration, its rear portion is a heeling condition simultaneously; Fiber feeding passage shrinks by this way, and promptly air flow is accelerated; There is a width that is 2M/M to the maximum the outlet, and is selected like this, and promptly to cross the speed of opening be such to air communication, and promptly the front end of the fiber that is booked at open region is changed towards the direction perpendicular to opening section; Fiber feeding passage is thus arranged, and promptly fiber is in fact freely held by this surface, does not in fact have direction to change in the limit of opening portion in other words.

The part of the device of representing among Fig. 1 of the present invention has a rotor and a known opening roller 1 of open-end spinning process by open-end spinning, and be general expression, this opening roller is supported in (just local expression) in the housing 2, can drive, opening roller 1 is equipped with known pin 3 or tooth (not shown), so that ribbon is divided into independent fiber.
Such as already mentioned, the opening roller parts with such opening roller are disclosed by the rotor and the open-end spinning process of open-end spinning, thereby are not described further.
Friction spun yarn drum barrel 6 is perforated (not shown), and adorns an air intake passage 7(Fig. 3 within it a), and this passage forms an air-breathing district R by its wall 8 and 9 on friction drum barrel 6 excircles.Wall 8 and 9 cylindrical form interior surfaces near friction drum barrel 6 extend, so as to stop as far as possible gas leakage flow to into.
Borrow in that produce by air intake passage 7 and along fiber feeding passage 5 airflow flowing, fiber 10 is separated by pin 3, and free-moving fiber 10 is maintained in the said air-breathing district on friction drum barrel 6 surface portions of rotation in feeding passage 5, this air-breathing district is limited by the opening 11 that feeds passage 5, and twisted at yarn shaping position 13 places at last, form yarn 12 in the borderline region in the air-breathing district that the wall 9 by air intake passage 7 forms, the yarn shaping position is positioned in the imaginary extended spot of wall 9 on the drum barrel wall next door of friction drum barrel 6.Friction spun yarn drum barrel 6 rotates to arrow U indicated direction.
For auxiliary twist yarn, also can discharge second friction spun yarn drum barrel 15 side by side with first friction spun yarn drum barrel 6 of mentioning, near first friction drum barrel 6, so that make the yarn that between two friction drum barrels, shrinks formation in the interval be become than the yarn that does not have second friction drum barrel 15 to be obtained to be eager to excel by twisting.
The rotation direction of friction drum barrel 15 is corresponding to the rotation direction of first friction drum barrel 6, and the both represents with U.Because it is identical that both turn to, therefore, the direction of motion of two drum barrels in shrinking interval region that end opposite.
Second friction spun yarn drum barrel 15 also can be perforated, and an air intake passage 16(who forms air-breathing district is housed represents with chain-dotted line in Fig. 3 and Fig. 3 a) to form air-breathing district R.1, wall 17 and 18 are housed in the passage.The wall 17 of (as shown in Figure 3) so is directed to above the air intake passage 16, the imaginary extension line that is this wall intersects by the imaginary extension line of friction spun yarn drum barrel 15 at yarn shaping position 13 places and wall 9, or put in a straight line, changed by the air-flow of air intake passage 7 and 16 is good at the fiber of yarn shaping position 13 places twisting like this, this air intake passage 7 and 16 is mutually towards opposite direction.But such possibility is also arranged, as Fig. 3 a is represented, make wall 9 and 17 be arranged to such correlation, promptly yarn shaping position 13 is positioned between the imaginary extension line of wall 9 and 17.
Air-breathing district R and length (not shown) R.1 are at least corresponding to the length L of opening 11.In order to obtain the uniform distribution of fiber on the length L of access portal 11, the width D of opening 11 (Fig. 3,5,6 and 7) should not surpass 2mm.Length L and width D form an opening section; Usually, term " opening " and " open cross-section " refer to the narrowest position of fiber feeding passage.
Fig. 1 represents is a fiber feeding passage 5 with gradient, and gradient represents with angle [alpha], and less than 90 °, passage 5 is by the wall 19(of the imaginary extension line of opening 11 and its underpart as shown in Figure 3) constitute.Compare therewith, do not have gradient at the feeding of the fiber shown in Fig. 4 path 10 5 at open region C place, and in fact its angle [alpha] is 90 ° with respect to the drum barrel surface, open region C has the height h of a minimum 10mm of being.All the other elements among this figure are corresponding to the element of Fig. 1, thereby represent with identical sequence number.Therefore, opening must be corresponding to the condition of said fiber feeding passage 5, and it also uses sequence number 11 represented.
As usefulness chain-dotted line and dotted line among Fig. 3 a are represented, do not hindering the fiber that moves freely under the situation of the drum barrel surface guiding of friction spun yarn drum barrel 6, fiber feeding passage 5 and 105 also can depart from solid line position shown in Figure 3.Fiber in those positions feeding passage is used sequence number 5.1,105.1 respectively and is represented with 5.2 and 105.2 in Fig. 3 a.
According to the position of those feeding passages, the β angle shown in Fig. 3 and Fig. 5 changes, and this β angle is constituted by the tangential plane T that runs through the line place of friction spun yarn drum barrel 6 by the opening symmetry plane E of corresponding feeding passage with at symmetrical plane E.
As representing with arrow S among Fig. 3 a, free floating fiber 10 has the trend of impacting friction spun yarn drum barrel 6 on the direction of representing with arrow S, more particularly, and in fact with the location independent of the feeding passage of representing with the β angle.In order to help fiber to change to said radial surface, passage 5 or an outer wall 20.1(of 105 are as shown in Figure 5) also can provide a given interval Q with respect to the surface of friction spun yarn drum barrel.By this way, gas leakage stream P is directed, and gives the trend of free floating fiber 10 with radial impact friction spun yarn drum barrel surface so widely.For same purpose, another measure is as only expressing one of them hole by hole 22(among Fig. 7) represented, the hole is on the inwall 20 of passage 5 or 105, in other words towards the be shaped wall in district 13 of yarn.
Disorder for fear of the Radial Flow route of above-mentioned free floating fiber 10, owing to be obstructed in the contraction at interval of excircle air-flow between friction spun yarn drum barrel 6 surfaces of wall 21 and rotation, do not causing that under the situation about contacting between this wall and drum barrel 6 surfaces, the gap H between wall 21 figure (Fig. 3) and friction spun yarn drum barrel 6 surfaces should keep little as far as possible.
In addition, or replace above mentioned measure, as represented in Fig. 6, the opposite direction slow astern that little gap H can rotate along the wall 8 towards U of air intake passage 7 is apart from Z, opens aforementioned circumference air-flow so that inhale in regional Z by air intake passage 7.
At last, shown in Fig. 6 and 7, wall 21 can provide a sweep 23 in the zone of opening 11, and this bent part is towards the opposite direction of the rotation direction of U, and it has increased the conversion of the air-flow of corresponding arrow S direction.
Each air intake passage 7 or 16(Fig. 3 are connected to a negative pressure source a) with known manner with pipe 24 or 25.In addition, friction spun yarn drum barrel 6 and 15 correspondingly is supported and drives with known manner, uses axis a as conventional letter.The driving of friction spun yarn drum barrel and supporting arrangement are known, are not purpose of the present invention.
What Fig. 8 represented is the remodeling of apparatus of the present invention, it is characterized in that: perforation friction spun yarn disk 56 has replaced friction spun yarn drum barrel 6.Disk 56 rotates towards rotation direction K, and accepts the free floating fiber of being carried by fiber feeding passage 57 10.This fiber feeding passage 57 is in tilted layout into the β angle with friction spun yarn disk 56, and its arrangement is similar to fiber feeding passage 5 and 105.
Fiber feeding passage 57 can be dressed up the inclined angle alpha less than 90 °, and mode is similar to the fiber feeding passage of Fig. 1 and 4, or α as shown in figure 10 is actually 90 °.
Shown in Fig. 8 and 11, air intake passage 58 can be widened to the opposite direction of the rotation direction K of friction spun yarn disk 56, so that in the zone of Z.1 indication, the air that exists on friction spun yarn disk 56 surfaces of motion can be inhaled before opening 59 to be opened, and enters in the passage 58.Passage 58 is connected to a negative pressure source (not shown) by Connection Element 64.
With use friction spun yarn drum barrel 6 relevant about gap H(Fig. 8) statement done, be suitable for using the friction spun yarn disk to replace drum barrel in a similar fashion.Equally, all be fit to about the bending shown in Fig. 6 and 7 with about the statement of flowing the opening of P by gas leakage.
Usually, it is useful shrinking in this manner as fruit fiber feeding passage, and promptly flow air stands to quicken within it, and the fiber that is transferred in air like this stands a pre-straightening at least.
During operation, more than the use of the device of narration is as follows:
Preface: test card is understood the peripheral speed of friction spun yarn drum barrel and is had conclusive significance in the air velocity of opening part or the relation between the fiber speed at opening part.
For example, what be determined is, when the ratio of the peripheral speed of the speed of opening part air and friction spun yarn drum barrel rises to 4: 1 value when above, the intensity and the uniformity of yarn have been reduced owing to the formation that has increased coil, for example, until ratio is 10: 1 o'clock, and then smart yarn just no longer can use.
But if the ratio of said air velocity and peripheral speed is selected in 2: 1 when following, intensity is also streaky smaller so, but still can obtain operable yarn, even it is also passable to have a ratio lower than 1: 1.Relation between the uniformity of quality and ratio is the same with relation between the ratio of intensity.
This influence is explained as follows:
If the peripheral speed that the free-fiber that the friction spun yarn drum barrel has a ratio to leave opening is high, fiber will be when being caught by the friction spun yarn drum barrel and be elongated so, and be undertaken in fact that yarn becomes the yarn of open position to form on the end on the circumferencial direction of friction spun yarn drum barrel.
Above-mentioned influence be situation with inclined fiber feeding passage, as shown in Figure 1, or have the situation of the feeding passage of vertically arranged end, as shown in Figure 4.
On the other hand, if the relation of the peripheral speed of the air velocity of opening part and friction spun yarn drum barrel is selected in the scope between 2: 1 and 4: 1, at the ramp way shown in Fig. 1 with α angle, compare with the use of the feeding passage shown in Fig. 4, just found following difference.
According to the path 10 5 of Fig. 4, have said ratio greater than 3, fiber is placed in the knitting position of spinning on the drum barrel increasingly, and when ratio increased, just becoming more can not be satisfactory.
But, use ramp way as shown in Figure 1, when the ratio of air velocity and peripheral speed during greater than 1: 1, fiber just is placed on the obliquity of friction spun yarn drum barrel increasingly so, this trend increases when peripheral speed reduces, and reaches maximum when said ratio is 4: 1, when further increase ratio, promptly by 4: 1 when above, fiber also begins to be placed in the knitting position of above-mentioned friction spun yarn drum barrel.
The said fiber obliquity of friction on the drum barrel be owing to there is aligning process in the feeding passage, thus not only be placed on the position of being aligned at the fiber on the friction spun yarn drum barrel, and also in the same direction as, this direction helps forming yarn ends.But if yarn drawing-off direction is such, the fiber that promptly has the discharging of tilting if the interior yarn of Here it is yarn drawing-off direction and passage feeds direction when opposite, bears further aligning when the traction yarn.This vantage point could preferentially be utilized.
Now explain how to obtain the obliquity of fiber on the friction spun yarn drum barrel with Fig. 1:
If the front end 10.1 of a fiber that is freely suspending 10 is caught by friction spun yarn drum barrel 6 and is transported to yarn shaping position 13 along the M direction, the afterbody free end 10.2 of this fiber is further carried towards the N direction with bigger speed by air-flow simultaneously, therefore, when front end 10.1 was covered the corresponding distance of arrow M, fiber 10 arrived position shown in dotted lines in Figure 1.
If the fiber that a present velamen is placed on the friction spun yarn drum barrel is directed by this way to the yarn ends in 13 formation of yarn shaping position, front end 10.1 is just caught by yarn ends so, and be held thus, and the remainder of yarn still attaches on the suction drum barrel, and be conducted through the yarn ends of shaping, arrive the zone of air intake passage 7 back and when getter action stops, be released up to fiber, by reverse drum barrel catch with clamping and once more the guiding by the lip-deep yarn ends of reverse drum barrel, catch by the air-flow of first drum barrel once more up to the pars fibrosa that is shortened.Afterwards, alternately repeat this process around fiber is winding to yarn.This yarn end that is wound on produces to a certain degree rotation, but this rotation is relatively little, close with the fiber end winding speed relatively be very little.Therefore, the difference of the process of once describing by method of the present invention and front is, on the one hand do not plan that fiber is undertaken on and be parallel to the position of yarn, also do not plan on the other hand rotation is delivered to yarn ends, and the rotation of top mentioned yarn ends only is the side effect of twining fiber process.
In order to prove this operating principle, photo as shown in figure 12 is provided, figure can be clear that fiber is undertaken on the mentioned obliquity thus.In order always to see the formation of yarn better, remove second drum barrel when taking a picture, therefore, although be to be formed yarn, yarn ends also is extremely loose.
Test shows, the obliquity of yarn on the friction spun yarn drum barrel as using shown in the γ angle, becomes than becoming big, and the γ angle becomes less in other words, and then fiber feeding passage is just bigger to the inclination of friction spun yarn drum barrel.But when in fact tilting to reach its maximum, α is similar to 0 °.
Although there be not second drum barrel, the explanation of producing yarn is, such as already mentioned, yarn ends is born certain rotation, because this rotates, the end that is discharged by drum barrel is rotated back into the top, up to being held by the air-breathing institute of drum barrel 6 once more.If yarn is not pulled, as shown in figure 12, so just produce fibre bundle gradually, fiber will keep obliquity on the friction spun yarn drum barrel within it.
Such as already mentioned, free floating fiber equally distributed condition in the feeding passage is the width D of opening 11; Use the width greater than 4mm, fiber has the great free degree mutually, and it should not surpass 2mm.Width will increase flow resistance during to 0.5mm.
Also verified is, situation as shown in Figure 4 with path 10 5, and fiber also not exclusively is positioned on the friction spun yarn drum barrel excircle direction (or perpendicular to yarn ends), and therefore aforesaid winding effect also is to exist in this distortion.Because fiber is to the precipitous position of the yarn ends more fiber of multi-turn of need reeling, this will cause the fiber of a harder winding, in other words twist yarn more tightly.In addition, have the danger of fiber tangible lopping in winding process of such position, therefore, even the tighter yarn of volume can not increase the intensity that needs.
Also must should be mentioned that, the air velocity of the speed of fiber and open region is not corresponding in constricted channel, but then, the ratio of the speed of open region fiber and friction spun yarn drum barrel excircle speed is conclusive to above-mentioned effect, therefore, air velocity is simply represented the variable that can survey, by means of this variable, can obtain an operational adjusted value.
Fig. 1 according to the present invention, the characteristics of the most preferred embodiment of the opening of fiber channel 5 are, have the shaping constriction of the petiolarea that the passage of opening do not hold, and strengthen air velocity in this way, so that make air flow turn to opening.Air-flow with such transformation is represented (as shown in Figure 1 and Figure 4) with arrow F.
The remodeling of the device of Fig. 8 to 11, wherein truncated cone shape friction spun yarn roller is not arranged on the diametric(al), shown in Figure 11 a, but imaginary tangential plane X is had an internal acute angle delta.This internal acute angle delta is included in this tangential plane X and the friction spun yarn disk is positioned to the right angle and comprises between the imaginary plane of pivot center Y of truncated cone shape friction roller 60.
What therefore, yarn shaping position 61 was arranged to tilt on same meaning.So air intake passage 58 must correspondingly be suitable for the yarn shaping position in order to the mode of preceding mentioning.
Except the already mentioned element that is suitable for air intake passage 58, the element of Figure 11 a is corresponding to Figure 11, and therefore, they are represented with identical sequence number.
By such being in tilted layout of yarn shaping position 61, fiber 10 is placed on the friction spun yarn disk 56.With 61 one-tenth heeling conditions of yarn shaping position, as representing with the δ angle.
By above-mentioned superior position, fiber 10 can be in the mode of having narrated, and the yarn ends that forms at yarn shaping position 61 places is reeled on every side.
