途に使用されている。2. Description of the Related Art A woven fabric comprising a reinforcing fiber bundle exhibits a high specific strength and a specific elastic modulus by forming a fiber-reinforced plastic formed into a predetermined shape by compounding with a synthetic resin. The composite material is widely used for general industrial use including aircraft use.

る問題がある。[0003] Reinforcing fiber yarns are thicker and more brittle than yarns used in general clothing fabrics. Therefore, in so-called shuttle looms, the winding length of the weft tube is short, the frequency of replacement is increased, and the diameter of the bobbin is also increased. Because of the small size, there is a problem that fluff is generated.

That is, the rapier loom is provided with a rapier sleigh that supports the rapier in order to stabilize the operation of the rapier and reliably supply the weft yarn, but the rapier enters and retracts between the upper and lower yarns at the opening of the warp yarn. In doing so, the rapier moves on the lower thread on the sley, and the warp yarn is liable to generate fluff due to rubbing with the rapier.

る。[0005] In particular, in a band-type rapier loom (also referred to as a flexible rapier loom; hereinafter, referred to as a "band-type rapier loom"), the band has a low rigidity and may be sent out while being bent, and the warp yarn is scraped by the band. Therefore, a high-quality reinforcing fabric cannot be obtained, and high-speed operation cannot be performed. In order to solve such problems, a band-type rapier loom has been developed in which hollow guides for guiding the rapier band are provided at regular intervals over the entire width, thereby avoiding rubbing of the warp yarn by the band and simultaneously realizing high-speed rotation. I have.

For guiding, the end of the rapier band is engaged with the groove of the hollow guide, so that the hollow guide becomes relatively large and its tip protrudes greatly, and the warp separates into a lower thread and an upper thread. May be an obstacle. Further, there is also a problem that the single yarn of the reinforcing fiber bundle is cut by the tip of the hollow guide penetrating into the fiber bundle of the warp yarn. In particular, when a carbon fiber bundle is used for the warp yarn, there is a problem that the tip of the hollow guide easily penetrates into the fiber bundle, and the fiber itself is also very brittle, causing a single yarn break and significantly fuzzing. is there.

製造法を提案した。To solve the above problem, Japanese Patent Application No.
In No. 301120, the rapier is supported by a rapier sleigh constituted by a convex portion forming an integral structure with a reed wing of a reed, and a lower thread of a warp is stored in a concave portion of the rapier sleigh, that is, a space formed between adjacent convex portions. We proposed a method for manufacturing a reinforcing fiber woven fabric.

よって、筬と一体構造をなすスレーの凸部が曲げられ、
使用回数が小さい段階で、凸部を有する筬羽の付け根部
が折れるという問題が発生した。However, the reed is generally formed thin so that the interval between the warp yarns in the fabric is reduced. Therefore, by the reciprocating reciprocating motion of the rapier on the sleigh, the protrusion of the sleigh, which is integral with the reed, is bent,
At the stage where the number of times of use is small, there has been a problem that the root of the reed dent having a convex portion breaks.

するという問題があった。As a countermeasure, there is a method of increasing the thickness of the reed. However, since the interval between the warp yarns in the woven fabric is increased and the gap between the reeds is reduced, the warp yarn moving up and down in this interval causes the reed to oscillate. The movement causes friction with the reed feathers to increase the generation of fluff of the reinforcing fibers. In addition, if the interval between adjacent protrusions, which form an integral structure with the reed, is reduced, it becomes difficult to clean the fluff accumulated between the reeds, which is hindered by the protrusions.

れる。DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides a method for manufacturing a reinforcing fiber woven fabric in which at least a warp is a reinforcing fiber bundle by a band-type rapier loom, wherein the rapier is supported by a convex portion of a rapier sleigh integrally formed with a reed of a reed. A method and an apparatus for manufacturing a reinforcing woven fabric for weaving while storing a lower thread of a warp yarn in a concave portion of the rapier sleigh. This reinforcing fabric is preferably applied to a composite material represented by a fiber-reinforced plastic.

００ＧＰａ以上の高弾性率糸、またはサイジング剤の付
着量が０．８重量％以下の糸は、僅かな擦過によっても
毛羽が発生し易い。[0014] The reinforcing fiber bundle in the present invention specifically refers to, for example, at least one fiber bundle selected from the group consisting of a carbon fiber bundle, a glass fiber bundle and an aramid fiber bundle. In particular, since the carbon fiber bundle is fragile and easily breaks due to rubbing, the effect of the production method of the present invention is great. Further, among the carbon fiber bundles, the tensile elastic modulus is 2
A high elasticity yarn of 00 GPa or more, or a yarn having a sizing agent adhesion amount of 0.8% by weight or less tends to generate fluff even by slight abrasion.

フィブリル化した繊維が正常な繊維に絡み合って毛羽を
誘発したり、強度が損なわれやすい。On the other hand, although aramid fibers generate less fluff due to abrasion, the fibers are fibrillated by the abrasion, and the fibrillated fibers are entangled with normal fibers to induce fluff or to lose strength.

When the number exceeds the number / cm, adjacent warp yarns or adjacent lower yarns come into contact with each other, and fibers come into contact with the convex portions of the sley.

でも損傷を受けたり、扁平性が損なわれてしまう。Further, the production method of the present invention is highly effective in a woven fabric using flat yarns made of carbon fibers having a yarn width of 4 mm or more. In a normal carbon fiber bundle having a yarn width of less than 4 mm, the yarn width is small, so that the influence is small.
The flat yarn described above has a small thickness, so that even a small external force is damaged or the flatness is impaired.

なるのである。According to the present invention, weaving can be stabilized even when a reinforcing fiber bundle having a large fineness is used. The range of the fineness of such a reinforcing fiber bundle is 1,500 to 200,000.
Extensive with decitex. In particular, PAN 2
A large tow carbon fiber bundle of 5,000 to 200,000 decitex is produced by dividing an acrylic fiber tow into 4 to 10 pieces. At the time of division, the acrylic fiber is cut, and the carbon fiber bundle becomes fluff. Although the state is large, even with such a carbon fiber bundle, the rapier does not rub against the carbon fiber bundle of the end yarn, so that the generation of fluff is reduced and the production of a woven fabric becomes possible.

とをいう。The rapier is a member in which a device called a rapier head, which is called a rapier head, is attached to the end of the band, and is a member for inserting the weft while entering and leaving the opening of the warp every one rotation of the loom. Further, a single-sided rapier or a double-sided rapier may be used. The rapier sleigh refers to a member for securing a passage when the rapier enters and retreats.

れるようにされている。The convex portion of the rapier sleigh supports the rapier main body when the rapier enters and retreats and smoothes its movement, so that the upper surfaces of a plurality of convex portions connect the respective upper surfaces at the same height. The lines are arranged horizontally. Further, in the concave portion formed between the adjacent convex portions corresponding to the convex portion, when the warp yarn separates into the lower yarn and the upper yarn, the lower yarn of the warp yarn is stored, and the contact with the rapier which enters and retreats is prevented. Has been to be avoided.

う。The interval between adjacent protrusions is n times (n = 1 to 15, n: integer) the interval between reeds. The "adjacent problem" is the distance between a certain convex part and its neighbor,
In other words, it refers to the arrangement pitch of the protrusions in the reed width direction.

mm. If it is less than 1.5 mm, the width of the concave portion becomes small, and it becomes difficult for the lower thread to be stored in the concave portion. If it exceeds 40 mm, when the rapier enters and retreats, the tip of the rapier may contact the convex portion. . To obtain more stable operability, the interval between adjacent protrusions is 2 m.
It is preferably from 30 m to 30 mm.

とがある。In the band-type rapier loom, when the rapier enters the warp yarn opening, a flexible band stored in a curved state is sent out from the storage section,
While trying to run on the upper surface of the convex part of the rapier sleigh with the band straightened, the band does not immediately become linear from the bent state, and varies depending on the material and dimensions of the band, It flies in a slightly bent state for about 30 cm. Therefore, the tip of the rapier attached to the band is 10-30
At a distance of about cm, it collides with an angle on the side of the convex part of the rapier sleigh, and the tip of the rapier further bounces and is on the side of the convex part of the rapier sleigh at a distance of about 60 to 80 cm from the storage part. May collide at an angle.

生を防止することができる。When such a collision occurs, an impact force acts on the side of the convex portion of the thin rapier sleigh. Due to the impact and the fatigue caused by the impact force, the reed is integrated with the convex portion at an early stage. It was found that the wings broke at the base of the base. According to the present invention, the occurrence of such inconvenience can be prevented.

In FIG. 1, a warp yarn 1 forms a lower yarn 1a and an upper yarn 1b at the time of opening, and a weft yarn 2 is supplied to the opening from a yarn supplying section. The reed 3 has reed wings 3a arranged at a predetermined interval, and the selected reed wing 3a has a convex rapier sleigh 3b (convex) formed integrally with the reed wing.
Are formed. The rapier 4 includes a band 4a and a rapier head 4b connected to the tip of the band 4a. Reference numeral 5 denotes a base 5 of a rapier sleigh.

ａとレピアスレーの基台５との擦過も回避できる。The reed 3 is formed by integrating a sley portion 3b which supports the rapier 4, stabilizes its movement and ensures the supply of the weft yarn, and a reed wing portion 3a. The upper surfaces of the plurality of sley portions 3b have the same height, and the lines connecting the upper surfaces are horizontal. In this way, by integrating the reed dent part 3a and the sley part 3b, there is no gap between the reed dent part 3a and the sley part 3b.
However, it does not accidentally enter a recess formed between the adjacent reed wings 3a. When rapier 4 moves, lower thread 1 of warp
a is located lower than the upper surface of the sleeving portion 3b, the lower thread 1a of the warp yarn is set by setting the rapier 4 and the lower thread 1a of the warp thread so as not to contact the base 5 of the rapier sleigh.
a can be prevented from rubbing against the base 5 of the rapier sleigh.

b, the interval between the convex portions of the portion A (for example, on the side closer to the band storage portion) is set to n = 1 with respect to the interval between the reeds, and the other portions B (for example, on the side farther from the band storage portion). Is set to n = 2, and a portion where the interval between the convex portions is partially close is provided. In this manner, in a portion where the interval between the convex portions of the rapier sleigh is small, the angle of contact with the side portion is reduced, the impact force is reduced, and the durability of the convex portion of the rapier sleigh is improved. In addition, in the part where the interval between the convex parts is large,
It is easy to clean the fluff accumulated between the reeds, and good work efficiency is secured.

The distance between the protrusions can be made partly dense between m and 20 cm. In this case, the interval between the convex portions of the rapier sleigh is reduced as a whole, so that the angle of contact with the side portion is reduced, the impact force is reduced, and the durability of the convex portion of the rapier sleigh is improved. In addition, the ratio of the portions A and B to the reed in the width direction is 1: 1 to 1: 2.
It is preferably about 0, and the ratio of the portion A does not need to be so large.

来なかった。COMPARATIVE EXAMPLE 2 A conventional reed having no reed sleigh protruding portion and a reed density of 0.85 / cm (pitch: 11.8 mm) and a conventional repier sleigh were used, and other manufacturing conditions were implemented. The same fabric as in Example 2 was produced in the same manner as in Example 2. There was a lot of fluff of the original yarn, and the carbon fiber bundle of the warp rubbed against the rapier head or rapier band, and fluff accumulated between the warp yarn sheet and the rapier sled. When the accumulation of fluff increases, the rapier head is lifted and the weft yarn cannot be normally gripped. Therefore, once the fabric length is 20 to 30 m, it is necessary to stop the loom and remove the fluff, and very continuous operation was not possible.

物が得られる。As is apparent from the above description, according to the method and apparatus for manufacturing a reinforcing woven fabric of the present invention, when a rapier is inserted into an opening of a warp yarn, the warp yarn has irregularities formed on the surface of the rapier sley. A method of weaving while holding the rapier with the convex part integral with the reed wings, which fits in the concave part, avoids contact of the warp with the lower surface of the rapier and the upper surface of the sleigh, and has high quality without fuzz due to rubbing with the rapier and the sleigh. A reinforcing fabric is obtained.
【００３９】また、レピアヘッドが当たる箇所は局部的

え、スレーの凸部が破損するようなこともない。Further, since the gap between the sley portions is locally narrowed at the portion where the rapier head hits, it can withstand high-speed operation, and the projection of the sley is not damaged.
【００４０】毛羽の少ない高品質の補強用織物となるか
