The present invention provides an improved method and device for producing an alternate S/Z twist plied braid and joined alternate S/Z twist plied yarns. The invention further provides an alternate S/Z twist plied braid and joined alternate S/Z twist plied yarns produced according to a process of the invention.
Description
Technical field
The present invention relates to improving one's methods and equipment for the production of alternating twisting plying braided fabric (alternate twist plied braid) and alternating twisting folded yarn (the joined alternate twist plied yarns) that couple together.The invention still further relates to and utilize this method alternately twisted and plied braided fabric of S/Z that obtains and the alternately twisted and plied yarn of S/Z that couples together.
Background technology
Now, use alternating twisting, twist with the fingers phenomenon certainly and produce the theory of alternating twisting folded yarn and know in the art.The file of the basic principle of describing alternating twisting and twisting with the fingers certainly comprises: " Self-Twist Yarn ", D.E.Henshaw, C ° of Merrow Publishing, Ltd., Watford, Herts, England, 1971; People's such as Breen RE27717; The US3225533 of Henshaw; People's such as Henshaw US3306023; Clendening, the US3353344 of Jr.; People's such as Backer US3434275; The US3443370 of Walls; People's such as Yoshimura US3507108; The US3717988 of Walls; The US3775955 of Shahand; And the US3940917 of Strachan.
For simplicity, will roughly do some comments about utilizing these technology to produce folded yarn.
Can pass through two or many single thread lines of alternating twisting, line is joined to one another, allow to use the release of the stored power of alternating twisting to make line twine to finish plying each other to form folded yarn then, namely term " is twisted with the fingers " certainly.With the form of simplifying, alternating twisting itself comprises the spaced points of holding the yarn thigh, twists described line in the centre position (being the center) of holding a little along a direction.This side at the center produces the twisting along a direction, and the opposite side at the center produces twisting in opposite direction.The center of the line after the twisting constitutes the twist against twist point, and is called " crosspoint (node) ".Significantly, twisting step in, power be stored online in.Put together side by side when two lines of similar alternating twisting, their end is held, and is allowed that when discharging the crosspoint, center and interact, the power of storage makes the line plying, that is, twine each other naturally.If the crosspoint of two lines is aimed at and discharge with plying before be connected or connect together, can strengthen this process, and make product more stable.
What will be appreciated that is, the moment of torsion that every line applies or twisting power roughly are directly proportional with wherein twisting amount, and when line was pooled capital, such power reduced.Therefore the step itself of pooling capital is proceeded, the twisting power that in every line, stores be reduced to certain a bit till, at this some place, in remaining twisting power and the folded yarn further the opposing power of twisting accurately offset.Therefore, if people begin with single line, the described line of alternating twisting also makes their plying, then in folded yarn, every line will be twisted end with remnants to a certain degree, described remaining twisting can be considered to some remaining storage of potential energy, to such an extent as to the too little opposing force that can not overcome in the folded yarn of the power that applies thus further carries out doubling twisting.In the stable folded yarn that forms by this way, the single twist amount that applies is always greater than the amount of doubling twisting.
In general, this remaining storage power or energy are not disadvantageous especially, and this depends on the type of the fabric of being produced by folded yarn.Yet when yarn during for the production of some product, such as based carpet or tufted carpet, the remnants twisting that exists in the single thread becomes very important, and this is that outward appearance by the product of its production causes.
For example, the folded yarn that consideration is formed by two single thread, in folded yarn, the value of the single thread twisting that applies equals 1.4 times (S=1.4P) of the value of doubling twisting.In this case, find that the fiber in the single line is basically parallel to the axis of folded yarn.Bunch family's carpet of being made by the yarn in this specification has two significant disadvantage, small relatively variation in the first manufacture process, such as the little variation of twisting between the axle, cause the reflective character of carpet lint bundle to change greatly, carpet can have fairly obvious striped outward appearance, and this is unacceptable.Second subject matter is under S=1.4P or bigger situation, single thread tends to keep it as the characteristic of single line, even it is also like this when plying, and tend to punish into independent single line in lint bundle tip, independent single line is visible, and makes carpet surface present unexpected " tendril " outward appearance.
Shown in the U.S. Patent No. 3443370 of above-mentioned Walls, also knownly produce yarn by alternating twisting more than two or the silk thread of more assemblings or many lines of yarn, and form the thing that is called as braided fabric by the plying step to previous folded yarn.
When forming braided fabric by previous twine, various power interact in each plying process, make to be difficult to estimate the twist that after described step, exists that therefore, the final products that obtain to have the twisting relation that meets with the expectation specification are quite complicated processes.
Yet U.S. Patent No. 4246750 has been described: by insert the specific twist in single thread, connect the crosspoint of described yarn, allow their plying together to form alternating twisting twine; Some line that alternating twisting is selected connects the crosspoint of described line, and allows described line plying to form braided fabric together; Can obtain to have the product of twisting relation that can estimate and consistent.
US4246750 has also described: at crosspoint place a plurality of plying alternating twisting yarns being coupled together allows can be in given interval to be increased severely by the numbers of poles of the line of HEAT SETTING add, and can increase energy input hardly, thereby increase the ratio defective product of this yarn significantly, and reduce the required cost of HEAT SETTING operation of unit length.
In addition, it has been described: HEAT SETTING braiding or the alternating twisting twine that couples together produce such product mouth, described product for example can be used to produce tufted carpet or can be divided into twine, and twine has the desired characteristic that can estimate, and can be used in individually during carpet makes.
U.S. Patent No. 4246750 has been described a kind of method of stablizing the twisted yarn product that forms, and may further comprise the steps: provide many single thread that are divided into many groups, and the yarn of keeping in every group is spaced apart from each other; At least one single thread in every group applied alternating twisting, and to form such yarn, that is, a series of twisting zone has the longitudinal separation zone that replaces S and Z twisting that is separated by the reverse crosspoint of twisting; Yarn in every group is placed to each other closely spaced relationship; Yarn in the position in crosspoint in every group is connected to each other; Allow the yarn in every group to twist with the fingers certainly, to form a plurality of alternating twistings plying braided fabrics, wherein twisting moment of torsion is basis equalization; Each alternating twisting yarn is applied extra alternating twisting, to form a series of imbalance twisting zones that replace S and Z twisting that separated by the crosspoint that couples together therein; Being placed to each other line closely, spaced relationship is vertically aimed at their crosspoint; In the position, crosspoint twine is connected to each other; And the plying braided fabric that couples together is heated to enough HEAT SETTING, and it twists the temperature of characteristic.
But U.S. Patent No. 4246750 does not still have explanation how in the position, crosspoint, particularly how in continuous processing twine to be joined to one another, thus, single thread, twisted and plied line and final braided fabric are processed under continuous process velocity, that is, do not make them stop to be used for knotting.
Being connected in the production environment like this is very difficult, because yarn tension is than higher after applying extra twisting, and the existing connection in the crosspoint in the yarn makes filament have low entanglement ability.Alternately the crosspoint of the twisted and plied yarn of S/Z is proved to be impossible reliable and reproducible the connection in practice.
U.S. Patent No. 5644909 discloses a kind of for processing folded yarn alternately and the method and apparatus of product.Near the crosspoint, form and connect.Connect yarn by ultrasonic bonding.These yarns have the solid duroplasts of small pieces, and supersonic welding is connected on the solid duroplasts of these small pieces to be carried out.This is disadvantageous, because it can cause inconvenience, itch and scratch.In the method for the disclosure, process stops off and on.This is disadvantageous for process velocity and place capacity.Second or the plying of pairing thigh end oppositely do not connect.
Therefore, need in this area to improve.The present invention aims to provide at least one solution and the improvement of mentioning in the problem at top.The present invention's purpose provides a kind of improved method and apparatus, and it can connect twine reliably, processes them simultaneously under continuous process velocity.

With many non-limiting example explanation the present invention.Further explain the present invention below with reference to the general diagram that Fig. 1 provides.With further with reference to Fig. 1-5 of alternating twisting folded yarn is shown.
As shown in Figure 1, in being used to form the equipment of yarn of the present invention, single thread 2,2a, 2b and 2c are mainly supplied with by yarn bag 1,1a, 1b and 1c by the supply of yarn supply source.
Being suitable for torque jet used in this invention is for example obtaining openly in the U.S. Patent No. 4074511.
Torque jet has central opening, and yarn 2,2a, 2b and 2c can pass central opening.Torque jet itself comprises many to entrance, is respectively 5 and 6; 5a and 6a; 5b and 6b and 5c and 6c optionally introduce compressed air in the entrance.The passage that passes for yarn 2-2a-2b-2c in entrance 5-5a-5b-5c and 6-6a-6b-6c and the torque jet 4-4a-4b-4c tangentially intersects.Therefore, if compressed air is introduced into the entrance 5 by each nozzle, the yarn that passes nozzle so can be subjected to the influence of air-swirl in each centre gangway, and is twisted in one direction.Subsequently, if compressed air is introduced in the entrance 6, yarn can be twisted in the opposite direction so.
Therefore, by compressed air being applied to air intake 5 and 6 ( difference 5a and 6a; 5b and 6b; 5c and 6c), obtain alternating twisting yarn 7,7a, 7b, 7c in the downstream of nozzle 4,4a, 4b and 4c.
When alternating twisting yarn 7,7a left torque jet 4 and 4a, they were connected at their place, crosspoint.Preferably, connection is homophase, means that the zone of identical twist direction and crosspoint are parallel to each other.
Alternating twisting yarn 7,7a can lump together at crosspoint fixator 8 places, wherein, the crosspoint of alternating twisting yarn 7 and 7a are coupled together.Such crosspoint fixator 8 can be entanglement nozzle (entangle jet) known in the industry.
Preferably, this connection procedure also can be applied to yarn 7b and 7c.Preferably, when connecting yarn 7 and 7a, carry out being connected of yarn 7b and 7c.Yarn 7b and 7c lump together as quickly as possible, and their crosspoint is coupled together in the fixator 8a of crosspoint.
Alternating twisting yarn 7,7a can form alternating twisting folded yarn 9 from twisting with the fingers or pooling capital together.Preferably, the alternating twisting yarn 7b that leaves crosspoint fixator 8a also can be in the same place from sth. made by twisting or plying with 7c.The alternating twisting folded yarn that obtains is represented by reference number 9a in Fig. 1.
Schematically illustrated these yarns of Fig. 2: S sth. made by twisting 100 and Z twist with the fingers 101 graded area; Interrupted crosspoint 102.
What will be appreciated that is, in order to make the yarn plying, is necessary to make nozzle 4 and 4a synchronous, makes twisting in the same direction be applied to yarn 2 and 2a simultaneously.Similarly, make nozzle 4b and 4c synchronously to twist simultaneously in the same direction.Described in hereinafter, according to the final effect of expectation, the relation synchronization similarly between the twisting that is applied by nozzle 4 and 4a and the twisting that applied by nozzle 4b and 4c perhaps can be asynchronous wittingly.
In this point, be useful with reference to figure 2, the schematically illustrated alternating twisting folded yarn of Fig. 2 is such as yarn 9.Therefrom as can be seen, shown in section comprise two reverse crosspoints 102 of twisting, twist reverse crosspoint and be considered to tangle by filament and couple together.Will be appreciated that, the section 100S folded yarn that between crosspoint 102, has the single thread by two Z twisting to form, when the yarn that couples together left crosspoint fixator 8, nozzle 4 and 4a had applied Z twisting, and S pools capital and forms.Then, in nozzle 11, yarn 9 is crossed twists, and by synchronously, makes the yarn downstream be twisted on the direction identical with yarn 9 to the air supply source of nozzle 11, produces uneven alternating twisting folded yarn 12.Identical situation is suitable for yarn 9a, and it is crossed twisting by spray nozzle device 11a, produces uneven alternating twisting folded yarn 12a.
In the outlet of twisting apparatus 11 and 11a, uneven alternating twisting folded yarn 12 and 12a lump together abreast, and their crosspoint is aligned with each other, and described crosspoint is connected to each other in crosspoint fixator 15.
In each torque jet device 11 and 11a, each alternating twisting folded yarn 9 and 9a are alternately twisted, and are preferably in phase twisted with the alternately twisted and plied yarn of S/Z that has formed.This causes uneven twisted and plied yarn 12 and 12a.These yarns 12 and 12a also lump together as quickly as possible, and their crosspoint couples together in crosspoint fixator 15.
Apply extra alternating twisting and produce very high yarn tension, so the fiber in the crosspoint or filament have low entanglement ability.In addition and since before between the alternating twisting yarn, produced unite connection (intermodal connection), the free degree of fiber and filament is very limited.
The inventor finds, can advantageously address this problem by following content.Between each torque jet device 11,11a and crosspoint fixator 15, be provided with yarn feed system 13,13a, to reduce the tension force among each the uneven alternately twisted and plied yarn 14 of S/Z, 14a, be reduced to the level that is suitable for crosspoint fixator 15 good operation.Therefore, before with uneven alternating twisting folded yarn 12 and 12a guiding crosspoint fixator 15, yarn feed system 13 and 13a have reduced the tension force in them.Can make yarn feed system 13 and 13a according to the principle known in this area, such as mip rolls (Fig. 6 a), the excessive feed rolls of capstan winch (Fig. 6 b), open roll system (Fig. 6 c), gear (Fig. 6 d), belt-type jaw (belt nip) (Fig. 6 e) or even by air (Fig. 6 f).
After crosspoint fixator 15, produce recombination line 16, it is directed into following processing 19, and following processing can be heat setting process, and wherein, the twisting characteristic that is applied to each component is finalized.The HEAT SETTING device can be any conventional heat-setting equipment that utilizes other form of steam, the infrared necessary level that can or yarn be risen to its characteristic of HEAT SETTING.In general, under the situation of synthetic yarn, be necessary the temperature of yarn is brought up to glass transition temperature, perhaps second order transition temperature, under such temperature, the stress in the yarn is disengaged.
Further describe the characteristic of composite yarn below with reference to Fig. 3-5.The characteristic of final products is directly related with the twist direction that is applied by each torque jet device.If by device 4 and the 4a twisting that applies and the identical or basic synchronization of twist direction that is applied by device 4b and 4c, the twine 9 that obtains so and 9a have the component of doubling twisting in the same direction.In addition, with their crosspoint rough alignment.Then, torque jet device 11 and 11a can twist in the same direction similarly, add twisting to folded yarn that the downstream produces.Afterwards, crosspoint fixator 15 couples together folded yarn at the place, crosspoint, the twisting of increase is arranged, as shown in Figure 3 therebetween.As shown, yarn 14 and 14a all have the S doubling twisting between crosspoint 102, and only per inch has the twisting of higher degree, and folded yarn is connected at the place, identical crosspoint that single thread is coupled together.
If discharge yarn and allow their plying after the crosspoint connects, folded yarn can be pooled capital or " twisting system (cable) " again each other so, forms yarn for example shown in Figure 4.Therefrom as can be seen, in order to distinguish, yarn 14a with shown in single thread twisting draw, yarn 14 plots " clean " line.Yet, should be noted in the discussion above that this only is in order to make accompanying drawing clearer, in actual product, yarn 14 looks basic identical with yarn 14a.Therefore, the line of doubling twisting can form cable to twist with the fingers certainly each other with the similar mode of line of single thread twisting.
Perhaps, if device 4b and 4c and twisting apparatus 4 and 4a are synchronous, but phasing is shaped as opposite twist direction, and when yarn arrives crosspoint fixator 15, their crosspoint will still keep aiming at, but the direction of doubling twisting can be opposite.Certainly, this can be also finishes by the amount that makes path between crosspoint fixator 4b and the crosspoint fixator 15 prolong a gap between the amount of a crosspoint length or the crosspoint, differs with introducing.Then, if the crosspoint couples together in crosspoint fixator 15, the product that obtains so can be schematically shown as Fig. 5, wherein, yarn 14 between the crosspoint 102 has S doubling twisting and the twisting of Z single thread, and the section between these crosspoints of yarn 14a has Z doubling twisting and the twisting of S single thread.Therefore, when crosspoint connection and release, folded yarn can not twisted system, and will keep state as shown in Figure 5.
If the twisted and plied yarn 14 of uneven S/Z and 14a in phase lump together, as shown in Figure 3, so after crosspoint fixator 15, they will stand from twisting with the fingers processing, produce the alternately twisted and plied braided fabric 16 of S/Z, as shown in Figure 4, wherein, for clear, alternately one of twisted and plied braided fabric of S/Z is shown as single white line.The reducing of the yarn tension that is caused by yarn feed system 13 and 13a also improved this from twisting with the fingers processing.
If the twisted and plied yarn 14 of uneven S/Z and 14a lump together anti-phasely, as shown in Figure 5, after crosspoint fixator 15, they will can not stand from twisting with the fingers processing so.Torsional tension in the yarn is opposite.Being connected of crosspoint among yarn 14 and the 14a makes yarn keep its uneven twisting, and also like this on the crosspoint, the yarn 16 of generation is actually such: yarn 14 and 14a are adjacent one another are, and are connected to each other at the place, crosspoint.
In a preferred embodiment of the invention, system 18 controls yarn feed system 13 and 13a according to the yarn tension of the recombination line of being measured by tensometer 17 16, makes that the yarn tension between crosspoint fixator 15 and the processing subsequently 19 changes minimum.In another preferred embodiment of the present invention, tensometer 17 is replaced by the device 20 such as tension arm, and it can gather yarn between crosspoint fixator 15 and processing subsequently 19.Under these circumstances, control yarn feed system 13 and 13a according to the yarn amount of gathering, for example by measuring the position of tension arm.
In another preferred embodiment of the present invention, alternating twisting folded yarn 9 and 9a are heated by yarn heater as known in the art (for example infrared heater) 10 and 10a in the upstream of torque jet 11 and 11a, so that filament is softer, and further promote thus and tangle in the crosspoint of improving in the crosspoint fixator 15.So, the mistake twist level in the time of can increasing twisting.The mistake twist level in torque jet 11 and 11a downstream also can increase.
In another preferred embodiment of the present invention, the hot fluid of similar hot-air or steam is used among torque jet 11 and the 11a, so that filament is softer, and further promotes thus and tangle in the crosspoint of improving in the crosspoint fixator 15.So, the mistake twist level in the time of can increasing twisting.The mistake twist level in torque jet 11 and 11a downstream also can increase.
In another preferred embodiment of the present invention, the hot fluid of similar hot-air or steam is used in the crosspoint fixator 15, so that filament is softer, and further promotes thus and tangle in the crosspoint of improving in the crosspoint fixator 15.
In another preferred embodiment of the present invention, on filament, can apply additive, with the friction between the minimizing filament, and further promote the crosspoint in the crosspoint fixator 15 to tangle thus.Additive is some liquid additive preferably.Can apply these additives by application member device (for example kiss roll, wetting nozzle etc.) 21 and the 21a in the yarn path upstream that is positioned at crosspoint fixator 15 as known in the art, perhaps these additives can be added to the fluid that is used in the crosspoint fixator 15.
At last, for described each embodiment, need control system 22 to make all actuator cooperations.
