Description
(1) technical field
The present invention relates to a kind of weaving method of woven fabric, be specially the woven fabric of warp and weft interweaving and use the weaving method of conventional loom, international Patent classificating number intends being Int.cl.
7DO3D 49/00.
(2) background technology
The woven fabric that industry is used (hereinafter to be referred as fabric) is commonly used to do the reinforcing material (also claiming skeleton or support) of polymer matrix composites.This fabric is produced on loom, because loom all adopts prismatic cylindrical roller that batches to batch fabric, therefore the woven fabric of producing (following machine) is planar rectangular shape (" composite handbook S.T.Peters, Handbook of Composites, Second Edition, Chapman﹠amp; Hall, London, UK, 1998, P405).Clearly, the fabric of this shape can be applicable to the composite (as laminated sheet material) of planar rectangular shape well.But the composite of planar rectangular shape only is the sub-fraction in the composite, and for the composite with non-rectangular shape or curve form requirement, the planar rectangular woven fabric obviously can not finely be suitable for, for example, have non-rectangular shape in manufacturing, as fan-shaped, or curve form, during as the composite of Rotation Shell Structure, for making fabric can satisfy non-rectangular shape or pasting gauffer does not appear in clothes at curved surface requirement, have to carry out profiling fabric dividing design, cutting fabric and spell shape work, then could with resin molding compound.This cutting flat fabric with the problem that the method that adapts to surf deform exists is: 1. intensity decreases: comprise that the fabric yarn after (1) cutting is discontinuous, fabric intensity is impaired greatly; (2) fabric after the cutting, the direction of yarn is wayward when distortion, has influenced the utilization of yarn strength, also is difficult to satisfy fully the requirement of strength design of composite; (3) when the fabric profiling is spliced, overlap joint will have certain lap of splice, makes the composite material surface out-of-flatness; Butt joint, then the fabric continuity is bad, and composite can reduce intensity; 2. quality shakiness: the fabric after the cutting, the limit yarn easily comes off, and influences processing and forming and quality assurance thereof; Irregular overlap joint and overlap joint quality restive also can directly influence the quality of composite; 3. cost increases: the contoured design of fabric, cutting and splicing have increased the manpower spending; Fabric cut across and wasted material, increased the cost of composite undoubtedly again.Cut out many disadvantages that fabric brings in order to overcome, someone has designed the technology that a kind of " filament winding process " makes curved-surface structure composite skeleton, for example, " composite technology " (Xiao Cuirong, Tang Yuzhang writes, the strap winding process technology of Tapered Cup, P293) has just been introduced in October, 1991 by publishing house of the National University of Defense technology.But this technology exists (because of being that the little strap overlap joint of width twines) described profiling overlap joint problem equally even more.In addition, this technology can't solve non-rectangular shape such as sectorial plane textile armature problem, can not adapt to curve form and change greatly or the composite skeleton requirement of more complicated.
U.S. Pat 5368076 (Process and apparatus for manufacturing rocketexit cones and the like, 1994) has been introduced a kind of process and equipment and technology of producing composite rocket conical nozzle fabric.This technology has directly adopted the formed body (cloth beam) of truncated cone, and it is fan-shaped that woven fabric is expanded into, and dock on both sides has the truncated cone shape identical with formed body, has solved special-purpose profiling splicing problem.But still there is following problem in this technology: 1. reed complexity.This method must adopt the special or special-purpose reed consistent with the formed body curved surface, makes reed shape and structure complexity; For the shape that keeps reed is consistent with the formed body curved surface, different formed bodys just needs different reed, so or reed of a great variety, or this method purposes is single; 2. density irregularity.This method directly is wound on fabric on the formed body (cloth beam), and the fabric weft count that ectonexine is reeled exists than big-difference, the quality disunity; 3. the technical purpose of this method is clear and definite, at the skeleton fabric of composite rocket conical nozzle, and the device-specific height, versatility is low, and product is also single.
(3) summary of the invention
At the deficiencies in the prior art, the technical problem that quasi-solution of the present invention is determined is, designs a kind of woven fabric, and it has the profiling good to formed body, and body is stable, and quality is unified.This fabric behind the machine, has non-rectangle flat shape or curved surface spatial form under weaving, need not process, and can directly be used as the composite skeleton of respective shapes.
Another technical problem that quasi-solution of the present invention is determined is, designs a kind of weaving method of above-mentioned woven fabric, and it does not need to transform reed, and is wide to loom equipment applicability, highly versatile, and rich choice of products.
The technical scheme that the present invention solve the technical problem is: design the woven fabric that a kind of warp thread, weft yarn interweave, the warp thread that it is characterized in that described woven fabric is not isometric, and be that warp thread is less than the strong point filling density behind the following machine, the woven fabric of the fan-shaped or curve form that warp thread is bigger than the weakness filling density.
The present invention for the technical scheme that solves described another technical problem is, designed a kind of weaving method of described woven fabric, this woven fabric is when weaving, warp thread adopts the creel warp let-off, cloth beam 6 adopts the method batching that the formed body 6 of variable cross-section is installed on batching roll shaft 7, it is characterized in that work beam 4 employings before the described cloth beam 6 are batched in the method guiding of batching the formed body 4 that same variable cross-section is installed on the roll shaft 5.
Fabric of the present invention has adopted the creel warp let-off when weaving, each is through warp thread of yarn bobbin supply, thereby does not lay the first stone or created condition for realizing that warp thread is isometric; Again since correspondingly design taked the formed body (work beam) of variable cross-section to batch cloth beam batching (rather than prismatic cylindrical roller and cloth beam of batching) with variable cross-section, formed body diameter larger part, the warp thread that licks is more, formed body diameter smaller part, the warp thread that licks is less, thereby the warp thread that can realize down woven fabric is not isometric; After not isometric warp thread and isometric weft yarn interweave, be that warp thread is less than the strong point filling density behind the machine under just forming, the woven fabric of the fan-shaped or curve form that warp thread is bigger than the weakness filling density.Because this following woven fabric fan-shaped or curve form is the shape moulding of formed body during according to looming weaving fully, therefore when it is used to do the skeleton of respective shapes composite, do not need cutting and processing fully, can satisfy the profiling requirement, and profiling is good, dimensionally stable directly can carry out compound.So fabric of the present invention is used for composite, have the saving material, reduce operation, reduce cost, plurality of advantages such as improve intensity and ensure the quality of products has practicality preferably and economic worth.
The inventive method is compared with prior art just batched roller to original loom cylindrical and cloth beam all correspondingly is designed to the formed body of variable cross-section, and does not need to change or the shape and structure of design specialized reed, therefore it is simple to have method, applicability is wide, highly versatile, advantages such as rich choice of products.

(5) specific embodiment
The common fabric 1 of simple tissue generally interweaves up and down by warp thread 2 and weft yarn 3 and gets (referring to Fig. 1), no matter it is to take fabric, or fabrics for industrial use, the fabric of gained also is rectangular shape, and there can be no exception whatever.The textiles of other shape if desired, only reliable cutting, splicing, moulding.For example the skullcap of textile material generally all needs to cut out 4-8 sheet, spicing forming type.Cut out unavoidable waste material; Splicing needs to use man-hour, so cost must increase.Generally can accept for taking the fabric splicing, but for fabrics for industrial use, as the skeleton of composite crash helmet, splicing then damages its intensity greatly.(with reference to Fig. 1) compares with traditional woven thing 1, and woven fabric 1 of the present invention is that warp thread 2 is not isometric, and is that warp thread 2 is less than the strong point filling density behind the following machine, the woven fabric 1 of the fan-shaped or curve form that warp thread 2 is bigger than the weakness filling density.The non-rectangle fabric such as fan-shaped must be that curved line is not isometric, and the isometric fabric of RADIAL.Described not isometric curved line is meant except that the limit yarn of fabric, and any arc yarn all is longer than the yarn of its inboard (near the center of circle one side) and is shorter than the yarn (referring to Fig. 2 (b)) of (away from the center of circle one side) outside it.The curved line of the present invention's design is a warp thread 2, and RADIAL is weft yarn 3 (referring to Fig. 2 (b), Fig. 2 (c)).After not isometric warp thread 2 interweaves with isometric weft yarn 3, be that warp thread 2 is less than the strong point filling density behind the machine under just forming, the woven fabric 1 of the fan shape that warp thread 2 is bigger than the weakness filling density.
The weaving method that the present invention weaves described woven fabric 1 is, this woven fabric 1 is when weaving, warp thread 2 adopts creel 8 warp let-offs, cloth beam 6 adopts the method batching that the formed body 6 of variable cross-section is installed on batching roll shaft 7, it is characterized in that work beam 4 employings before the described cloth beam 6 are batched in the method for batching the formed body 4 of the same variable cross-section of installation on the roll shaft 5.The weaving process of the inventive method is (referring to Fig. 7): draw warp thread 2 from the bobbin 8 (a) of creel 8, behind thread-carrier rod 9, penetrate heald 10, under the effect of shedding mechanism (not shown), warp thread is divided into bilevel shed open, weft yarn 3 passes through from shed open, and warp thread 2 interweaves at fell 14 places with weft yarn 3 and forms fabric 1.Fabric 1 by formed body 4 and fabric guide roll 13 tractions or guiding, is wound on the fabric 1 that is made on the cloth beam 6 behind a pair of compress roller 11, length adjuster 12.Formed body 4 is installed in to batch on the roll shaft 5 and by its transmission and batches fabric, gives cloth beam 6 batching through fabric guide roll 13 again.Cloth beam 6 kinks are equipped with the frictional disk (not shown) in the side of cloth beam 6 on batching roll shaft 7, another frictional disk (not shown) is packed on the batching roll shaft 7, and by the effect of frictional disk, batching roll shaft 7 can drive cloth beam 6 revolution batching.This structural design can make fabric 1 closely be wound on the cloth beam 6.
Obviously, the shape of fabric 1 is by the shape control of formed body 4.Fabric warp thread 2 length that are wound on formed body 4 more than half warps are big, and filling density is little, and are wound on the warp thread 2 length weak point of minor radius, and filling density is big.The shape of fabric 1 is the expansion curved surface of formed body 4 along warp thread 2 directions.This curved surface fabric in theory can endless, then depends on warped length in practice.
The inventive method has adopted the creel warp let-off when weaving this fabric, promptly each is through a yarn bobbin supply warp thread (the original beam of a loom feeding system of warp of loom does not re-use), thereby does not lay the first stone or created condition for realizing that warp thread 2 is isometric; (be the truncated cone formed body owing to having taked corresponding variable cross-section formed body 4 again, referring to Fig. 2 (a)) batch that (rather than prismatic cylindrical roller that batches batches, but the present invention do not get rid of take prismatic cylindrical roller that batches to batch), formed body 4 diameter larger parts, the warp thread 2 that licks is more, formed body diameter smaller part, the warp thread 2 that licks is less, thereby the warp thread 2 that can realize down woven fabric 1 is not isometric, and weft yarn 3 is isometric, but the filling density of fabric does not wait.Be not difficult to find out that the amount of curvature of fan-shaped fabric of the present invention and the size of sector length only depend on the size of truncated cone formed body 4 cone angles and the size of frustum of a cone height, and irrelevant with other factors.In other words, the shape of adjusting frustum of a cone formed body 4 can be weaved various fan-shaped fabrics.When this fan-shaped fabric is used to do fan-shaped composite skeleton or truncated cone composite skeleton, can not do any cutting (lower interface need be handled in the back), directly compound getting final product.Saving of labor, material-saving, save time, and the globality of gained composite and intensity but improve greatly.Because the shape of described fabric 1 is directly related with formed body 4, so fabric of the present invention 1 also can be called the profiling fabric.
As a same reason, when adopting different formed bodys 4, just can obtain difform curve form fabric 1.For example, when adopting the olive shape formed body 4 shown in Fig. 3 (a) to batch, just can get the fabric 1 shown in Fig. 3 (b), i.e. spirogyrate or wheel the form of the foetus fabric 1.The limit portion warp thread 2 of this fabric 1 is not isometric with central warp thread 2, and the filling density of limit portion is big, and central filling density is little.Again for example, when adopting the concave shaped formed body 4 shown in Fig. 4 (a) to batch, just can get the fabric 1 shown in Fig. 4 (b), promptly the horse-saddle fabric 1.The limit portion warp thread 2 of this fabric 1 is long, and central warp thread is short, and the filling density of limit portion is little, and central filling density is big.Again for example, adopt Fig. 5 or billiard table shape formed body 4 shown in Figure 6 or the frustum of a cone and cylinder to be combined to form type body 4 when batching, can obtain the corresponding shaping fabric 1 shown in its figure.Fabric 1 shown in Figure 5 is big in formed body 4 minor radius place filling densities, and the filling density of long radius place is little, and warp thread 2 is formed body long radius director, and the minor radius place is short; Fabric 1 shown in Figure 6 is big in formed body 4 minor radius place filling densities, and the filling density of long radius place is little, and warp thread 2 is formed body long radius director, and the minor radius place is short.Also be as a same reason, when adopting gained shape fabric 1 to be used to do respective shapes composite skeleton, can not do any cutting (lower interface need be handled in the back), directly compoundly can obtain high strength monolithic abnormity composite, simultaneously also saving of labor, material-saving, save time.Should be noted that: though the present invention has provided the embodiment of several formed bodys commonly used 4 and gained respective shapes fabric 1 thereof, but other formed body 4 and gained respective shapes fabric 1 thereof that it does not have the limit actual capabilities to need, so it is not limited by described embodiment.
On ordinary loom, through the turning to of brest beams, make fabric 1 downwards around to work beam 4 from the fabric 1 of fell 14.Fabric 1 beginning contact with work beam 4 and the point that is subjected to its gripping winding point.Because brest beams is a horizon bar, when the present invention adopts the work beam 4 of variable cross-section to batch fabric, fell 14 is to the fabric length between work beam 4 winding points, meeting is difference with the difference of work beam 4 radiuses, therefore adopt variable cross-section formed body 4 to batch generally and can produce the skew of weft problem: fabric 1 from fell 14 to formed body 4 the winding point the distance of process, different and different with the radius of formed body 4.Formed body 4 most through locating, fabric wrapping point is shorter with the distance of fell 14, means that warp thread is shorter, and at the minor radius place, the distance of fabric wrapping point and fell 14 is longer, means that warp thread is longer; On the other hand, the most linear velocity through locating to batch fabric 1 of formed body 4 is bigger, it is less that the linear velocity of fabric 1 is batched at the minor radius place, the linear velocity that causes weft yarn 3 to be advanced by warp thread 2 pullings is bigger at the long radius place, the place is less in minor radius, therefore, weft yarn 3 is the run-off the straight distortion in being pulled process, arrives the asynchronism(-nization) of formed body 4.Weft yarn 3 at first arrives the winding point of formed body 4 at the maximum (the actual coiling) of long radius, later on successively to the minimum place of minor radius (the actual coiling) transition, weft yarn 3 until the least radius place also is wound up on the formed body 4, weft yarn 3 wire in the shape of a spiral on formed body 4 like this, weft yarn is no longer vertical with warp thread.The problem that skew of weft is brought is that weft yarn intensity can not make full use of, and then has caused the intensity decreases of integral fabric.Exactly because prior art has just adopted complicated curved surface profiling reed so.
The present invention does not adopt the technical method of transforming reed, directly adopts the original flat reed of loom, and the benefit of doing like this is that practicality is good, applicability wide (for example common fly-shuttle loom, arrow shaft loom, gripper shuttle loom etc. can be suitable for), and cost is low.The skew of weft problem that exists in order to solve the flat reed of direct use, the further feature of the inventive method is near the design of fell 14 places a pair of compress roller 11 to be arranged, and the appropriate position is equipped with length adjuster 12 (referring to Fig. 7,8 (a), 8 (b)) between compress roller 11 and described work beam 4.Described appropriate position embodiment is meant above loom front rest.The effect of described length adjuster 12 be size adjustment fell 14 according to the shape of formed body 4 or variable cross-section radius to the fabric length between the winding point, its radius with formed body 4 winding points is directly proportional.Described length adjuster 12 can have different version, and the concrete design of embodiment is a spring rotator type length adjuster 12.It is by the group rotor 12 that one group of spring is supported or control is arranged along the loom width, and quantity can be 6-20.The high and low position of each rotor 12 can be regulated by the shape of actual winding form or formed body 4 respectively.Be specifically through fabric 1 that compress roller 11 comes out by above the rotor 12 time by its jack-up, relevant around the radius size on the formed body 4 by the height of jack-up with fabric 1.Big by the height of jack-up at formed body 4 more than half fabrics 1 through locating, little by the height of jack-up at the fabric 1 at minor radius place, rotor 12 substantially also is the profiling shape of formed body 4.Fabric 1 is by after the jack-up, increased distance from fell 14 to winding point, recruitment also is big at the long radius place of formed body 4, the place is little in minor radius, thereby sluggish most be winding to time on the formed body 4 through locating weft yarn 3, make a weft yarn 3 can arrive the winding point of formed body 4 simultaneously, the weft yarn 3 that is wound on the formed body 4 is vertical with warp thread 2, do not have skew of weft, fabric 1 pastes clothes well with the curved surface of formed body 4.Regulate the position of described rotor 12, can adapt to the shape of all formed bodys 4.
The effect of described compress roller 11 is to keep fell 14 to be horizontal, thereby can utilize the original opening of loom, wefting insertion and beating-up mechanism.
Another of the inventive method is characterised in that the described cloth beam 6 that batches variable cross-section formed body that can be separately installed with on roll shaft 5 and the batching roll shaft 7 more than 2 or 24 and same variable cross-section, weaves simultaneously.When the axial length of Woven fabric was little, design can further improve weaving efficiency like this, in weaving process, can obtain the profiling fabric more than 2 or 2.This many fabrics woven method simultaneously both had been fit to weave the profiling fabric of identical or same kind simultaneously, also were fit to weave different or different types of profiling fabric.Designed spring rotator type length adjuster 12 also adapts to this many fabrics woven needs simultaneously fully.
The effect one of the described fabric guide roll 13 of the inventive method is the coiling directions that change fabric 1, reels for cloth beam 6; The 2nd, rely on the spring pressurization, increase the purchase capabilities of 4 pairs of fabrics 1 of formed body, batch with better profiling.Fabric guide roll 13 can be the rod-type fabric guide roll 13 (shown in Fig. 8 (a)) of former loom, and the bus that is applicable to formed body 4 is the situation of straight line; Also can be designed as a group rotor 13 (shown in Fig. 8 (c)) that leans against on the described formed body 4.Rotor fabric guide roll 13 is applicable to that the bus of formed body 4 is the situation of curve, and its each rotor can make fabric 1 be close on the formed body 4 under the pressure of spring, and fabric 1 does not produce relative slip with formed body 4 when take-up, thereby profiling is good.This rotor fabric guide roll 13 also adapts to this many fabrics woven needs simultaneously fully.
Also should be noted that, the shape of fabric 1 of the present invention only depends on the formed body 4 and the auxilliary creel warp let-off of joining, other requirement is not proposed for use equipment and technology, so traditional loom and technology can woven fabrics, the present invention can weave equally, that is to say that any one tissue fabric in plain weave, twill, satin weave or their alternative construction can be weaved; Any one fabric in individual layer, bilayer or the multiply cloth also can be weaved, and those of ordinary skills do not need to carry out creative work and can finish.
The described principal character of the inventive method is to have adopted the formed body 4 of variable cross-section and cloth beam 6 to batch when weaving.In practical operation, 6 designs of the formed body 4 of this variable cross-section and cloth beam are: the special use of making 2 minor diameters (for example 40 mm dias) batch roll shaft (moulding axon) 5, batching roll shaft 7 and can with the different shape that batches roll shaft 5,7 assembly of batching roll shaft basic configuration formed body 4,6 independently.The basic configuration formed body is made in pairs, a formed body 4 of making work beam, and another is the formed body 6 of cloth beam.When weaving, select for use as required or assembly is installed and used temporarily.The benefit of this method design is: 1. independently basic configuration (as cylinder, the frustum of a cone, billiard table, saddle body etc.) formed body both can independently use (shown in Fig. 2 (a), Fig. 3 (a) etc.), can be used in combination also that (the big small cylinder and the frustum of a cone are combined, as shown in Figure 6), make things convenient for use, also reduced the outfit quantity of formed body 4.2. the material of formed body 4 can be varied, as adopting plastics, aluminium alloy etc., can weight reduction, and conveniently transport and reduce cost.3. for the fabric of highly little (warp thread 2 radicals are few relatively), can in same weaving process, finish weaving of a plurality of identical or different shape fabrics 1 at the same formed body that batches a plurality of identical or different shapes of configuration on roll shaft 5 and the batching roll shaft 7.Certainly, also can produce the work beam 4 and the cloth beam 6 of different shape variable cross-section as required, directly use this work beam 4 and cloth beam 6 when weaving.
Though fabric of the present invention and method are conceived to the composite skeleton, it is applicable to the common fabric of taking fully, as makes single seam skullcap, profiling trousers etc.Both main distinctions are material therefor and special number difference thereof.The material that the former uses all is the material of high-strength flatness, and as aramid fiber, carbon fiber, glass fibre etc., number number is generally hundreds of spies; The latter then uses routine to take fiber.
