Description

With long fibre is be made method, structure and the shaped device thereof of flat tubular structure of tool extensibility, high expansibility of raw material

Technical field

The present invention relates to a kind of is method, structure and the shaped device thereof that raw material is made the flat tubular structure of tool extensibility, high expansibility with long fibre, and it is primarily aimed in the product improvement of fiber web wadding and the method improvement to tensile strength, extensibility and the bulkiness of the uniformity, different directions.

Background technology

No. the 3747162nd, the patent of invention that the U.S. was checked and approved on July 24th, 1973, it discloses a kind of known to produce the mechanism of the long fine laminated construction that curls, and this mechanism comprises that one forms the device that becomes band, a linear roller devices, a series of high-pressure jet expanding unit, a pair of transmission guide wheel, a pair of guide wheel, a guide groove pipe, an air pressure or hydraulic cylinder and a board.

The curling long fine band that one treaty is made up of 30,000 filaments makes the device that becomes band by a container transport to this; And be delivered to linear roller devices again and it is unfolded by making the device that becomes band should grow fine band; Carry the air-flow that utilizes its ejection via the high-pressure jet expanding unit to make the curling long fine stratum reticulare that launches that forms from linear roller devices again; Secondly by this jet expanding unit fiber web layer is delivered to delivery roller to prepare to carry out the winding of S shape, fiber web layer is delivered to the guide wheel place, can make this fiber web layer form the winding of S shape when delivery roller; Be delivered to the guide groove pipe that is constituted by the both sides panel again by the guide wheel place, this guide groove pipe is linked on the one side panel by air pressure or hydraulic cylinder and is the action that swings, form a continuity fiber band by roller control by this guide groove pipe hangs on board the fiber web layer of expansion, and constitute a crossing stack structure of making by the long fibre of typing that curls jointly by the continuous fibers band of this guide groove pipe that swings and roller control.Yet, when using this known mechanisms, have some defectives, comprising:

The first, after leaving the guide groove pipe, the fiber web layer of expansion will be the lateral wave shape wave to launch, and this makes the both sides of this fiber web layer form thin situation.

The second, this guide groove piping is the state that swings, that is the bottom of guide groove pipe ties up to the dead point, both sides and is reciprocating motion.When the speed of guide groove pipe bottom arrives its minimum of a value 0 when being positioned at the dead-centre position of both sides (that is), and when it moves to position, central point between the dead point, both sides, its speed is maximum, at this moment, it is long that the time that the bottom of guide groove pipe rests on the dead point, both sides rests on time of position, central point, because launching the velocity ratio of fiber web layer feeding is certain value, this moment, guide groove pipe position was when the dead point, both sides, curling length heavier and that ductility is low was fine when release was positioned at the position, central point than it, therefore, this stratified fiber stratum reticulare is thin along its center line part than two side portions.

The 3rd, the continuous fibers tape speed of controlling than roller owing to the speed that is positioned at the swing of guide groove tube face plate bottom is fast, therefore between the fiber web layer crossing stack to connect the angle very little, in other words, long fine formed fiber web series of strata are vertical with it by curling, that is the operating direction of this crossing stack structure (MD) is laterally vertical, and therefore, this laminated construction provides less tensile strength at its operating direction.

Secondly, a little less than the cohesive force between the decussating fibers stratum reticulare is also extremely thin, and make combination closely between the lamination, this crossing stack structure has also shown a kind of relatively poor dimensional stability simultaneously, and is particularly obviously not enough along its weight of its midline and thickness.Therefore, must melt the generation that mode such as typing reduces these problems by resin, tailor's cushion or heat.

Summary of the invention

Main purpose of the present invention is to solve or to reduce above-mentioned generation of both having sent one's regards to topic.

The invention provides a kind of is be made method, structure and the shaped device thereof of the flat tubular structure of intersection of tool extensibility, high expansibility of raw material with long fibre, be primarily aimed at the shortcoming of prior art, new Apparatus and method for is provided, utilize through the long fine of the typing of curling to have the intersection stratum reticulare structure of balanced tensile strength, and make it have good stretching, extension recovery, dimensional stability and swollen degree etc. for raw material produces at operating direction and horizontal direction.

The present invention uses the long fibre through the typing of curling, be wrapped on the fiber web former with certain force of strain and speed, the fiber web former will grow fine intersect continuously twine, lamination launches and drawing-off, with form uniformity and have balanced tensile strength in longitudinal and transverse direction, size is stable and stretch restorative good fiber web layer; As for without the long fine of the typing of curling as also possess ductility, for example elastomer, recessive crimped fibre (latent-crimpedfibers) etc. can be unfolded, the material person of drawing-off and crossing stack also all can use in the present invention.By adjusting the superficial velocity (hereinafter referred to as launching ratio) that the fine band of length is wrapped in the pace on the fiber web former and launches district's expansion cingulum, make machine direction can reach 10 to 70 degree, yet more satisfactory angle is 30 to 60 degree with respect to the angle of horizontal direction (CD); And reaching the intersecting angle that makes fiber and superimposed fiber becomes 20 to 140 degree angles, and its more satisfactory angle is 60 to 120 degree.

Illustrate: the pace of twining the fiber web former when fiber band is adjusted under the optimal cases with launching ratio, and machine direction can keep near miter angle with horizontal direction (CD), and the angle that this moment, fiber intersected with superimposed fiber is then near an angle of 90 degrees; With such combination, machine direction can obtain best high isostatic strength in the flat tubular structure that has launched, its operating direction (MD) is 1: 1 ratio with the strength ratio of horizontal direction (CD), therefore, basically all do not have the relative thin weakness regardless of by any direction the fiber web layer structure being pullled, the flat tubular structure made from the method for intersection also has extraordinary stretching, extension recovery, dimensional stability and high expansibility.

Because continuous flat tubulose fibre structure is to be twined by long fine intersection of the typing of curling, between the filament and between the decussating fibers layer good cohesive force is arranged all, therefore the processing of can finalizing the design again in addition can be used in purposes such as ready-made clothes, sleeping bag, bedding, furniture, has therefore avoided the shortcoming of traditional lamination web.

Under fixing tension force and speed, fiber is wound in to do expansion, drawing-off on the former and intersect moulding can avoid traditional forming method to form the situation of thinner thickness in fibroreticulate both sides, and the weight differential of fiber web layer after the moulding, especially near middle weight difference; Twine the expansion ratio of feed speed and fiber web former by the long fine band in the Wrapping formed device feeding of control district, can obtain its best balanced tension force and stretching force at operating direction (MD) and horizontal direction (CD), effectively avoid conventional art at operating direction (vertically) relatively poor tensile strength and dimensional stability, avoiding conventional art simultaneously need be by resin, tailor's cushion, heat is melted typing and is waited the shortcoming that increases cohesive force between lamination, thereby acquisition has preferable drawdown, pliability and thicker structure have been improved the aesthetic property and the warmth retention property of sleeping bag and warming ready-made clothes etc.The present invention can use separately or in conjunction with other skill to solve the shortcoming of known intersection forming structure.

Because specialty fibers angle of the present invention reaches the accurate control mode to web width, intersect flat tubular structure except having kept the strength advantage of spunbond Nonwovens, specifically improved the elastic force extensibility of spunbond Nonwovens, swollen degree and flexibility simultaneously; The flat tubular structure of intersection of the present invention need not increase resin basically, machinery is entangled with as typing processing such as tailor's cushions, can use above typing processing typing if necessary, but therefore product can seem harder yet.

Intersecting shaped structure because of the present invention is to be formed by methods such as default fixedly tension force, machinery control accurately its expansion, drawing-off and intersections, therefore the stress at every single fiber all is similar to, so leave and launch cingulum when entering transport when intersecting shaped structure, under no tension force, lax state, also can keep its dimensional stability and the uniformity; This kind intersection moulding flat tube shape structure can be used in warming ready-made clothes, sleeping bag, bed group and furniture combination etc., process and need not to impose again other typings, for example utilize resin, tailor's cushion, add low heat of melting fiber and melt processing etc., therefore the above-mentioned processing mode of general using can reduce the pliability and the swollen degree of product; Unique elasticity advantage of intersection moulding flat tube shape structure of the present invention, can allow and transport through long-range, the fiber web manufactured goods that processes such as storage cause compression are through slight pullling, can recover due swollen degree and elasticity easily after shaking up, especially better when using elastic woven material to arrange in pairs or groups flat tubular structure of the present invention, fiber web can be not destroyed because of the elasticity drawing-off of cloth, known via resin, tailor's cushion or heat are melted the typing cotton-wool or are intersected forming structure, this reproducing characteristic can not be provided, because adhered between individual fibers or between the decussating fibers layer, being together with each other can not be by freely replying behind the compressed structural relaxation again.

Flat tubular structure of the present invention and spunbond Nonwovens have very evident difference, the present invention can allow fiber and horizontal direction (CD) be miter angle, decussating fibers stratum reticulare after the expansion then intersects so that preferable high isostatic strength to be provided with 90 degree mutually, must will remake typing processing with respect to the conventional spunbond Nonwovens and just can use, product of the present invention then can directly use; Therefore the present invention intersects moulding flat tube shape structure provides more soft and more bulk product.Moreover the present invention can use the long fibre through the typing of curling, and spunbond relatively filament is to be reeled off raw silk from cocoons by outspoken the connecing of the spinning of extruder, there is no the typing of curling, so therefore the present invention can represent preferable stretching, extension recovery; Spunbond Nonwovens cotton-wool has lower machine direction angle, and each monofilament all do not have a crimpiness, in addition hard processing stereotyped structure and make it form low non-woven cloth or the web of a kind of hard and swollen degree.

Fiber web former of the present invention also must be allowed has the long fibre of the curling typing of many groups to be delivered to the feeding district simultaneously, next and in the expansion district launch, if desired, the present invention also can utilize one step, and with the different long fine bands that feed arrangement fed, possess different kinds of fibers, fibre weight, fiber section and other combination variation respectively according to it to form the fiber web that constitutes by different fiber properties; Otherwise, as desire to reach above-mentioned similar fiber combinations mode, other conventional methods then must use comparatively costliness and step more, press down or comparatively complicated crossing stack mechanism reaches.The kinds of fibers of any kind of almost, for example nylon, polyester fiber, polypropylene fibre, elastomer etc. (above only simply outline several), all can be applicable to use among the present invention, the present invention does not simultaneously also have the restriction of fibre weight, and multiple fiber section, also all can be applicable among the present invention as circle, triangle or quadrangle etc., in addition, the variation that other are different, when increasing additive etc. as the distortion on fiber top layer, in polymer and desiring to provide special fiber properties or function in fiber web layer, also all applicable among the present invention.

The specific embodiment

As shown in Figure 1, be first kind of embodiment provided by the present invention, it comprises the Apparatus and method for part, in order to make the flat tubulose fiber net structure of intersection that the long fibre of the typing of curling is made for raw material, it mainly comprises two feed arrangement 2a and the 2b that separate, and this two feed arrangements system is positioned at the both sides at a distance of 180 degree angles; The device 4 of one expansion, drawing-off and crossing stack is called fiber web former 4, and a transport 6.The fine fibre bundle 1 of length of finalizing the design once curling is in feeding in order to the former 4 with fiber band expansion, drawing-off and crossing stack respectively by both sides feed arrangement 2a and 2b, again by this fiber web former 4, the curling long fine fiber net structure that intersects flat tubulose of moulding is delivered to transport 6, then furls equipment by one again and furled.

Each feed arrangement 2a and 2b include a container 8a and a 8b respectively, and in order to store long fine raw material, a series of roller 10a and 10b are then in order to also to be launched and to feed former 4 with fibre bundle 1 by deriving among container 8a and the 8b respectively; Though do not show among the figure, it has a mechanism in order to carrying and control this feed arrangement 2a and 2b twines this fiber web former 4 with clockwise or counter-clockwise direction, in order to produce the flat tubulose fiber net structure of being made by the long fine raw material that curls of intersection, this mechanism does not show it mainly is because it is not a principal character of the present invention.

Extremely shown in Figure 5 as Fig. 2, this fiber web former 4 comprises two groups of expansion cingulum 12a and 12b of being furnished with soft pin, between two groups of conveyer belts, be provided with simultaneously two curved panel 14a and 14b, wherein one group is launched the side that cingulum 12a system is located at curved panel 14a of combination and 14b, another group is launched another side that cingulum 12b then is located at curved panel 14a of combination and 14b, simultaneously, the expansion cingulum 12a of each group and 12b its extend respectively a part in two outsides of curved panel 14a and 14b, enable be wound in former 4 on curling typing long fiber bundle 1 amplexiform mutually; Extremely shown in Figure 4 as Fig. 3, launch cingulum 12a and 12b and comprise upper and lower two groups conveyer belt group respectively, one group of slow conveyer belt group system position is located in the feeding district, former 4 top, organize separately speed faster the conveyer belt group then be located in the expansion district of former 4 belows the position; As shown in Figure 3, be positioned at the conveyer belt group of both sides, feeding district, former 4 top, represent with label Fca and Fcb respectively, it includes two separately and separates and identical conveyer belt, and driven by slow roller, and make the both sides conveyer belt group of position in launching cingulum 12a and 12b all have identical rotating speed, therefore, cingulum 12a and 12b are launched in both sides in the feeding district, and the superficial velocity of its conveyer belt group is identical; As for, in feeding district, be provided with two separately and the advantage of identical conveyer belt, be to increase and enter colluding of fibre bundle 1 of feeding district and pull and the strong point, use and avoid in fibre bundle 1 is transmitting and touching in the feeding district the process, filament wherein produces the puzzlement of being entangled with; The design of these two conveyer belts all has consistent design at both sides conveyer belt group Fca and Fcb (as shown in the figure) respectively, also has identical structure respectively and forms and superficial velocity, also is parallel to each other between two conveyer belts simultaneously.Being furnished with coarse soft pin in the extension of the surface of conveyer belt in addition makes fibre bundle 1 stably be delivered to the expansion district in order to enough frictional force to be provided; Because the both sides in the feeding district respectively are provided with two conveyer belts respectively, therefore in the feeding district, launch the lower end of cingulum 12a and 12b conveyer belt group Fca and Fcb simultaneously, respectively be provided with corresponding two groups of pinwheel La and Lb respectively, its surface is provided with fine needle, and its superficial velocity is positioned at the conveyer belt group in feeding district for fast, uses the filament (as shown in Figures 3 and 4) that grasps on the corresponding conveyer belt.

When the typing long fiber bundle 1 that curls is contacted with the soft pin of rough surface of conveyer belt group Fca and Fcb in the feeding district respectively, it moves down with slower speed, filament then keeps its parallel position respectively and not separated or be unfolded mutually in the fibre bundle 1, when the leading edge of fibre bundle 1 moves to conveyer belt group Fca and Fcb below and pinwheel La and Lb junction, filametntary leading edge is rotating speed, and pinwheel La and Lb surface fine needle grasp faster.

As shown in Figure 5, because it is fast that the superficial velocity of pinwheel La feeds the speed of conveyer belt group Fca in the district, its filament is crawled on long fine fiber band, and makes its main part with fibre bundle 1 separate, and then still holds surely for the soft pin on the conveyer belt group in the feeding district as for main part; In ensuing operation, remaining fiber band continues by conveyer belt group in the feeding district drives to bottom offset admission velocity pinwheel La faster, to such an extent as to all filaments are all crawled; Because pinwheel La grasps each filament in regular turn with fast speeds, each filament that is positioned on the pinwheel La also is parallel mutually and is separation gradually; Produces the fiber web wadding that launches in pinwheel La surface institute, it is more former, and to enter the thickness that feeds the fibre bundle 1 of distinguishing the conveyer belt group thinner; When the fiber web wadding leading edge of launching is moved downward to the junction, top of conveyer belt group Sca and Scb in pinwheel La and Lb and the expansion district, the filament leading edge of fiber web wadding on pinwheel La and Lb, the speed that is is faster and be positioned at the thinner soft pin of conveyer belt group Sca and its surface of Scb that launches the district and grasp; It is different as for conveyer belt group Sca and Scb with conveyer belt group Fca and Fcb in the aforementioned feeding district. and be a broad and single conveyer belt design.Because the superficial velocity of conveyer belt group Sea and Scb is fast than pinwheel La and Lb in launching the district, therefore the surface detail Microsoft pin of conveyer belt group Sca and Scb grasped from fiber band leading edge place during filament was and launches to distinguish, and making its main part separate with fibre bundle 1, this main part is then still held for the fine needle of pinwheel La and Lb surely; In ensuing operation, remaining fiber web wadding then continues to drive displacement downwards by pinwheel La and Lb and admission velocity is launched conveyer belt group Sca and Scb in the district faster, and makes all filaments be unfolded all that the trickle soft pin of conveyer belt group Sca and Scb grasps in the district; Owing to formed deployed configuration on conveyer belt group Sca and the Scb in launching the district, and then the curling typing long fibre net that forms uniformity, approaches, and its filament system is parallel to each other.

Superficial velocity ratio by launching between district conveyer belt group Sca and Scb and feeding district conveyer belt group is so-called expansion ratio, launches the angle that ratio has determined the orientation angle and the crossing stack of fiber, below will have further to be described in detail.Conveyer belt group Fca and Fcb that the superficial velocity of pinwheel La and Lb feeds the district are fast, but the conveyer belt group Sca and the Scb that launch to distinguish are slow; Because the motor wheel that this pinwheel La and Lb system are separated in order to fibre bundle 1 monofilament with bunchy, simultaneously the thin fiber web wadding of produce is delivered to the conveyer belt group Sca that launches the district and Scb doing further expansion, so this pinwheel La and Lb do not change the expansion ratio of last manufactured goods.Yet the adjustment of pinwheel speed mainly is that Denier (denier) number according to fibre bundle, the degree of curling and the bonding degree of fibril etc. are decided, and can not cause in the time of so can making filament separate expansion from the fibre bundle of bunchy and be entangled with and destroy.

Another kind of example of the present invention as shown in Figure 6, fiber web former 4 can include four groups in addition and launch cingulum 12a, 12a-1,12b and 12b-1, to replace the aforementioned design that only has two groups, each group is launched cingulum and is included two conveyer belt groups that conveyer belt constituted being located at the feeding district and be located at a conveyer belt group that conveyer belt constituted launching the district, the combination that launches cingulum in each group shown in Figure 6 is all consistent with the described person of Fig. 2, shown in this figure grade 12a and 12b; Expansion cingulum 12a-1 and the 12b-1 system that has more two groups shown in Figure 6 has identical structure with Fig. 3 to Fig. 5 described expansion cingulum 12a and 12b, except launch cingulum 12a-1 and 12b-1 be in correspondence with each other, but its with launch cingulum 12a and 12b and be an angle of 90 degrees setting.As expansion cingulum 12a and 12b shown in Figure 3, each group launches cingulum 12a-1 and 12b-1 distinctly all has a pair of pinwheel La-1 and Lb-1 is located between feeding district and the expansion district; Launch cingulum and pinwheel at these newly-increased two groups, the main mode of operation of fiber web former 4 is identical with aforementioned person, yet comparatively roomy former 4 can be produced comparatively roomy flat tubulose fiber net structure.Typing is long fine owing to curl, has good adherence between its fibril, therefore, if two groups of spacings of launching cingulum are too big, then filament promptly is difficult in the fibre bundle of bonding and is separated, as shown in Figure 6, if can shorten two groups of spacings of launching between cingulum, then by two groups of support forces that launch between cingulum, and put on expansion strength on the filament, can overcome the adherence that is had between this filament, after being overcome as this interfibrous adhesion strength, then curling the filament of typing can be by even and smooth-going expansion, and can produce the flat tubular structure of specification unanimity after its adhesion strength is overcome.More graphic explanation below will be arranged.

As when the width of fiber web former 4 increases, newly-increased expansion cingulum can be along the surface distance of curved panel 14a and 14b and average the setting, the expansion cingulum of for example newly-increased six groups, eight groups or ten groups etc.; Therefore the present invention is arranged on the group number that launches cingulum on the former 4 and is not limited.

As shown in Figure 1, this transport 6 is to comprise that two rollers 16 and a conveyer belt 18 provided thereon form, and this conveyer belt 18 is driven by roller 16, in order to being reclaimed conveying by the flat tubulose fiber net structure of the intersection after 4 moulding of fiber web former.

The present invention first kind of embodiment as shown in Figure 1, its method of operating and step program as described below:

(1) be respectively equipped with feed arrangement 2a and the 2b that two components are opened in the both sides of fiber web former 4, next, the fibre bundle 1 of the typing of curling, the first of its fiber by container 8a via feeding and launch roller 10a and carry the expansion cingulum 12a that reaches the feeding district; During expansion cingulum 12a in the contact of the first of fibre bundle 1 is moved, promptly by to be that slow speed is carried fibre bundle 1 downwards than roller 10a input speed, in identical operations, 1 while of fibre bundle is wound in former 4 in a clockwise direction; In addition, fibre bundle 1 first of curling typing is in addition by container 8b, through feeding and launch roller 10b and send to the expansion cingulum 12b that is positioned at the feeding district, during expansion cingulum 12b in the contact of the first of fibre bundle 1 is moved, promptly by being that slow speed is carried fibre bundle 1 downwards than roller 10b input speed, when feed arrangement 2a spends around 180 in a clockwise direction in former 4 the place aheads, the second portion of the fibre bundle 1 of curling typing is promptly via container 8a, through feeding and launch roller 10a and send to the expansion cingulum 12b that is positioned at the feeding district and touch with it, at the same time, feed arrangement 2b also spends around 180 in a clockwise direction at former 4 rears, the second portion of fibre bundle 1 of typing curl this moment then again via container 8b, through feeding and launch roller 10b and send to the expansion cingulum 12a that is positioned at the feeding district and touch with it.

(2) be positioned at the curling typing fibre bundle 1 that the feeding district launches cingulum group below, when its front end contacts with pinwheel La and Lb, pinwheel La and Lb grasp it with superficial velocity faster, therefore this filament promptly is unfolded under the situation of tension force being subjected to simultaneously, import expansion cingulum 12a and 12b simultaneously and be positioned on the conveyer belt group of launching the district, and its speed is fast than pinwheel La and Lb also; When the typing fibre bundle 1 that curls is continued to carry by expansion cingulum 12a that is positioned at the feeding district and 12b, then promptly be positioned at the fiber net structure that the expansion cingulum 12a that launches the district and 12b form this flat tubulose simultaneously.Also can adjust simultaneously the width of fiber band and the speed that fibre bundle 1 is conveyed into fiber web former 4 by adjusting the position at the expansion cingulum group superficial velocity ratio (being referred to as to launch ratio) that launches district and feeding district, therefore, anyone all can change the basis weight of this flat tubular structure by this, and adjusts the included angle A of fiber web layer and horizontal direction (CD) as shown in Figure 1; Comparatively ideal mode is, this inclination angle with miter angle in operating direction (MD) and horizontal direction (CD) ratio with 1: 1, so can provide equal tensile strength, obtaining best balanced tension force, and design of the present invention can reach this 45 desirable degree angles.In order to satisfy the specific demand of product, anyone also can via adjust this included angle A greatly about 10 degree between 70 degree, and reach required product tension force, stretching force and swollen degree.

(3) in the winding action that continues, as shown in Figure 1, when feed arrangement 2a moves to the rear of fiber web former 4, perhaps as shown in Figure 2, when it moves in the face of curved panel 14b, this moment as shown in Figure 1, feed arrangement 2b then moves to the place ahead of fiber web former 4, perhaps as shown in Figure 2, move in the face of curved panel 14a, the third part of curling typing this moment fibre bundle 1 is via container 8a, by feeding and launch roller 10a and send to the expansion cingulum 12a that is positioned at the feeding district and touch with it, identical, the third part of the fibre bundle 1 of the typing of curling this moment is then via container 8b, again by advancing, sending to the expansion cingulum 12b that is positioned at the feeding district to reaching expansion roller 10b touches with it; This program fully according to 1., 2. and 3. 3 programs repeat start in regular turn; By aforesaid operations, can make the long fine continuous flat tubulose fiber net structure that on fiber web former 4, is shaped to of curling typing, and then carrying arrival transport 6 to be collected.

Extremely shown in Figure 10 referring to Fig. 7 simultaneously, be another kind of example provided by the present invention, the two strands 0.25 meter wide long fibre of curling typing is sent by both sides container 8a and 8b respectively, it also is wound in one 2 meters wide fiberizing device 4 with the speed of 0.25 meter of per second, and this speed is identical with the expansion cingulum speed of launching the district; Expansion cingulum speed in the feeding district is that perhaps per second is 0.03125 meter in 1/8 of the expansion cingulum speed of launching the district, is 8 so it launches ratio; Extremely shown in Figure 10 as Fig. 7, per eight seconds, fibre bundle 1 is sent from container 8a and 8b and is launched to move between cingulum 12a and 12b 2 meters distance to both sides, wherein, the position that Fig. 7 is moved when showing 0 second, the position that Fig. 8 is moved when being presented at the 8th second, the position that Fig. 9 is moved when being presented at the 16 second, and Figure 10 position of being moved when being presented at the 24 second; During this period, the first of fibre bundle 1 is expanded to 2 meters by 0.25 meter in launching the district, because container 8a and 8b system move but 180 degree of being separated by along same direction, the both sides fiber web layer after therefore launching also is corresponding states mutually.Yet the fiber web layer that launch both sides is strengthened overlapping under feed arrangement ongoing operation feeding mutually each other, and the long fine flat tubulose fiber net structure of typing that curls after the expansion of Xing Chenging as shown in Figure 1 promptly continues to be made.

As shown in Figure 6, another example of the present invention, it shows a kind of four groups of designs that launch the alternative aforementioned two groups of expansion cingulums of cingulum that utilize, 0.25 the wide long fibre of curling typing of meter is sent by both sides container 8a and 8b respectively, it also is wound in one 2 meters wide fiber web former 4 with the speed of 0.25 meter of per second, and this speed is identical with the expansion cingulum that launches the district; Because four groups in feeding district are launched cingulums system and move with identical speed, and in launching the district four groups launch cingulums and also move with identical speed, but that speed is positioned at feeding district person is fast, identical operations mode shown in its mode of operation system is graphic as described above.For example, after eight seconds, extremely shown in Figure 10 as Fig. 7, the first of fibre bundle 1 touches the expansion cingulum 12a that has a fiber web former 4 of 2 meters wide in, fibre bundle 1 is expanded to 2 meters by 0.25 meter in launching the district, the direction of fiber web layer launches to form between cingulum 12a and 12b the inclination angle of 45 degree in both sides simultaneously, but at the expansion cingulum 12a-1 and the 12b-1 that increase by two groups of soft pins of tool, as shown in Figure 6, after the 8th second, the filament that touches with expansion cingulum 12a is expanded to 2 meters by 0.25 meter in launching the district, but the fibre bundle 1 that touches with exhibition tooth cingulum 12b-1 in launching the district only is expanded to 1 meter by 0.25 meter, this be since fibre bundle 1 with launch time that cingulum 12b-1 touches with launch four seconds of evening time that cingulum 12a touches.Therefore, fiber web layer still keeps miter angle as mentioned above, as shown in figure 11.Launch cingulum 12b-1 delaying in time because this touches, the fiber web layer kenel that causes it to launch is all in full accord, and no matter whether this expansion cingulum 12b-1 is arranged on the fiber web former 4; Identical situation also is applicable to that the fiber that launches cingulum 12a-1 launches.As previously mentioned, newly-increased two groups of advantages of launching cingulum 12a-1 and 12b-1 are in order to reduce the expansion cingulum spacing of contact fiber both sides, and overcome the adhesion cohesive force that fibre bundle 1 is possessed, so can make the flat tubular structure of shaping reach even and smooth-going effect; As utilize the fiber web former 4 of broad, then get final product the flat tubulose fiber net structure of broad, in the feeding district and the expansion cingulum that launches the district and increase then be of value to and overcome the adhesion strength that long fine band is had, and make the operation of its expansion more smooth.

Moreover, another embodiment as shown in figure 12, two bundle fiber bundles 1 can be sent into by both sides container 8a and 8b respectively, it has the fibre bundle with different kenels shown in Figure 1, fibre bundle 1 shown in Figure 1 is very consistent with the described fiber band of present embodiment, and on its fiber band width, have speciality such as identical thickness, density and continuity, make the flat tubular structure of intersection that it produced on outward appearance and characteristic, have homogeneity and consistent structure, and have balanced tensile strength in all directions, Stability Analysis of Structures and good tensile elasticity and recovery characteristic are provided.Yet, fiber band as shown in figure 12, it is the fibre bundle that fiber is divided into some tuftlets by a special device that increases before it imports fiber web former 4, for example a kind of guide pin or roller 10a and 10b cut apart of this special device; This makes each filament in the fiber produce beam splitting effect and space and have certain spacing, and this one separates system and decide according to the design of this segmenting device.This utilizes different fiber combinations, it distinctly includes some fubril bundles that separate, a kind of to have xenogenesis material fiber formation be the flat tubular structure of intersection that raw material is made with the long fibre of typing that curls and can produce, and it all can utilize same Apparatus and method for of the present invention to reach.And intersect flat tubular structure by this method xenogenesis material fiber that is made, it has identical in itself structure and speciality, mainly comprise the tensile strength that has in all directions equilibrium, the rerum natura of Stability Analysis of Structures and extension recovery is provided simultaneously, the architectural difference that only has part therebetween, as shown in figure 12, be included in superimposed fiber along moulding, have many blank spaces on it, and in the structure that overlaps, produce many cavities, do not have fiber therebetween, therefore, the flat tubular structure of its intersection of producing has a kind of structure outward appearance as lax braidings such as mesh silk thread and fishnet holes, then has some holes between filametntary intersection contact.This structure provides some special product speciality, higher air permeability for example is provided via hole, make it possess air permeability and good, and have low-density, high elasticity and characteristics such as excellent support are arranged, and can be used as the part spare part of mattress and furniture assembly, to satisfy its actual demander.This structure has further represented the present invention and has possessed elasticity and versatility in the actual use.Present embodiment also can be used separately, and perhaps the embodiment that discloses among other each embodiment with the present invention merge to use.

Moreover, according to another kind of example of the present invention, please referring to Figure 13 and shown in Figure 14, the applied fiber band of the present invention, it does not limit its Denier, weight, material and width; The design opposite with example shown in Figure 12, the present invention in addition can provide a kind of and known general crossing stack structure different, and have less or almost do not intersect the flat tubulose stratum reticulare structure of folding line, and this structure possesses surperficial uniformity is arranged; Use a kind of fiber band of thin and broad, in order to substituting the thicker and narrow fiber band that uses usually, and can produce surperficial unanimity and the flat tubulose stratum reticulare structure of no folding line between lamination.For example, in the example formerly, utilize the fiber band (as shown in figure 13) of 75 centimeters of width to substitute the fiber band (as shown in figure 14) that uses 25 centimeters of width usually, in feeding fiber web former 4, therefore can reduce or eliminate the folding line between crossing stack in the flat tubular structure; This is because fibre bundle shown in Figure 13, its width has three times wide, and before making it no show launching the district entering former 4 feeding district, it can twine three times in the feeding district, therefore, is arranged in the folding line between feeding district crossing stack, compared to thicker, the narrower fiber band of known utilization in the lamination junction formed obvious folding line, can almost be eliminated in fact,, and make this flat tubular structure not have obvious folding line in fact because of the present invention utilizes the mode of broad fibre bundle; Further showed elasticity and the variability of the present invention on using again by this example.

At the two layer web interlayer that intersects, its angle is suitably with an angle of 90 degrees, and makes it have identical intensity at operating direction (MD) and horizontal direction (CD); Fiber web layer angle as for other then can be by adjusting the translational speed that feed arrangement 2a and 2b twine fiber web former 4, and reach at the expansion ratio that launches expansion cingulum between district and feeding district; Special demands when using in order to satisfy reality, anyone can make the angle of this fiber web layer maintain 20 degree between 140 degree, with tensile strength, extensibility and the swollen degree that adapts to special demands.What deserves to be mentioned is, the zone of the fiber web layer of this expansion between its first and second portion, leave from the second portion of fiber web layer and the zone between third part with a suitable angle and to fall into this transport 6, so this angle has determined the tension intensity ratio of the flat tubular structure of this intersection between operating direction (MD) and horizontal direction (CD).

This launches to intersect flat tubular structure compared to the most important difference of traditional stratified fiber stratum reticulare place for the present invention, person provided by the present invention is a successional tubular structure, its overall structure possesses preferable uniformity is arranged, comprise its edge or middle body, Figure 15 has then shown a kind of design that possesses dimensional stability, good extensibility and high expansibility.Yet known fiber web lamination method shown in Figure 16 then is the lamination of a kind with the fish scale design, it can be pushed aside layer by layer, therefore it is lack of consistency between lamination, cohesive force is low, have relatively poor balanced tensile strength at operating direction (MD) and horizontal direction (CD), and the dimensional stability deficiency.

As shown in Figure 1, feed arrangement 2a and 2b have identical height with respect to fiber web former 4 positions in the feeding district, both are 180 degree separately, and its with respect to former 4 in a clockwise direction around, yet, this feed arrangement 2a and 2b also can be on identical height with respect to former 4 in feeding district, and both can also different angles be separated, and with different directional rings around former 4; Therefore, so long as these two groups of feed arrangements are located at feeding district and the top of launching district's separator bar, it is raw material and the flat tubular structure that launches moulding that the present invention can be made into the typing fibre bundle 1 that curls by it.

Please referring to shown in Figure 17, be the second embodiment of the present invention, the Apparatus and method for that a kind of manufacturing is the flat tubular structure of intersection of raw material by the curling long fibre of finalizing the design comprises one group of feed arrangement 2, the device 4 of one group of expansion, drawing-off, crossing stack, can be referred to as fiber web former 4, and a transport 6.The fibre bundle 1 of finalizing the design once curling is in feeding in order to the former 4 with fiber expansion, drawing-off and crossing stack by feed arrangement 2, and make by the moulding of this fiber web former 4, the flat tubular structure of long fine intersection of a moulding can be transported to transport 6.

Feed arrangement 2 includes a container 8, and in order to store fiber, a series of roller 10 is then in order to also to be launched and to feed former 4 with fibre bundle 1 by deriving in the container 8 respectively; Though do not show among the figure, it has a mechanism and twines this fiber web former 4 in order to carry and to control this feed arrangement 2 with clockwise or counter-clockwise direction, is the flat tubulose fiber net structure of intersection that raw material is made in order to produce with the long fibre that curls.

To shown in Figure 4, this fiber web former 4 comprises two groups of expansion cingulum 12a and 12b of being furnished with soft pin, and two curved panels as Fig. 2, the composition of relevant this former 4 and control mode all and Fig. 2 of the present invention first embodiment extremely shown in Figure 4 identical.

About the mode of operation of second embodiment of the invention is close with first embodiment, but only need as the described one group of container 8a of first embodiment get final product except this second embodiment.It is slower than the speed that is derived fibre bundles by roller 10 that other difference is included in the speed of expansion cingulum 12a in the feeding district and 12b in addition, for example, velocity ratio as first embodiment, substitute original 1/8 by 1/16, because the difference on this speed, therefore single group feed arrangement can contain lid by Fig. 7 to shown in Figure 10 must be by the All Ranges of two groups of contained lids of feed arrangement; Launching ratio in order to ensure it is 8, make at the expansion cingulum that launches the district to launching the octuple of cingulum in the feeding district, therefore, not shown like Fig. 7 to Figure 10, the fibre bundle 1 that second embodiment is derived by container 8, the speed of its Wrapping formed device 4 is for launching to distinguish whole two times that launch cingulum speed, in other words, in eight seconds, the circle (360 degree) that the Wrapping formed device of container 84 is complete, the third part of fiber is touched with expansion cingulum 12a, originally only twine half-turn (or 180 degree) in order to replace, perhaps only the fibre bundle 1 of its second portion touches with expansion cingulum 12b, elasticity that present device and method possessed and variability more than have been described, make the flat tubular structure of its manufacturing possess changeable fibre weight, the angle of crossing stack, and by the Denier number of adjusting fibre bundle 1, the speed that container 8 is derived and the expansion ratio of fiber web former 4, and can increase its system productive rate.
