Description

System and Method for manufacturing unbalanced woven fabric

The present invention relates to a technique for producing an asymmetrical fabric, and more particularly, to supply a warp yarn so that a plurality of binder yarns and low melting point fiber yarns are arranged in a uniformly arranged reinforcement fiber and the edge of the reinforcing fiber, and in a direction perpendicular to the warp yarn Supply reinforcing fibers or spread reinforcing fibers to the wefts, grab the ends of the supplied wefts and pass them through the open inclined interior, release and cut the caught wefts, and then hold both ends of the enclosed wefts and position them into the designed position. In addition, the present invention relates to a manufacturing system and method for producing asymmetrical fabrics by applying heat and pressure while pulling the weft yarn by the designed weft spacing.

In general, composite materials refer to a mixed material in which two or more materials are mixed to improve the overall material properties. In general, composite materials include FRP (Fiber Glass Reinforced Plastics) composites. Such FRP composite material has a composite material laminated / cured while impregnating a resin (thermoplastic resin, thermosetting resin) in a reinforcing fiber such as carbon fiber, glass fiber, aramid fiber, etc. in a mold.

The type of reinforcing fibers applied to the composite material is provided in the form of yarns, bands, or woven fabrics. In general, the reinforcing fiber woven fabrics are provided by weaving plain weaves having a 1: 1 ratio of warp and weft yarns. It is common to be. In general, the reinforcing fiber woven fabric is woven by a general weaving machine, by supplying the reinforcing fibers to the warp and weft yarn, opening the warp yarn, engraving the weft yarn, and then weaving by hitting the body.

On the other hand, when the reinforcing fibers are applied to warp and weft yarns in a general weaving machine, there is a high possibility that the reinforcing fibers through the body needles are twisted or deformed due to the structure in which a plurality of fibers (filaments) are combined. Therefore, the widening of the reinforcing fibers in the width direction, that is, in the case of spreading reinforcing fibers, there is a problem that it is more difficult to apply as a weft yarn because the deformation in the width direction is large even with a small impact.

In addition, in order to weave asymmetrical fabrics in which the ratio of warp and weft yarns is different through a general weaving machine, it is necessary to perform batting (hitting the body without putting the weft yarns). However, even with this punch, the ratio of weft to warp yarns produced was limited to about 3: 1.

On the other hand, the contents of the weaving machine that weaving by direct weaving and weaving by the body as another structure for the upper mouth in the weaving of the reinforcing fibers are disclosed.

In this case, even if the weft is caught by the weft, since the body needle is carried out there was a fear that the deformation of the weft to which the reinforcing fibers or spreading reinforcing fibers are applied. In addition, as the weft loosen from the bobbin is supplied, deformation, such as twisting of the weft, may occur in the indentation process. In addition, there was a high possibility that the loosening would occur at the edges (selvedge, both sides of the fabric width direction) due to the combination of a simple warp yarn and a weft yarn.

In addition, the weft yarn is cut and then enters the weft yarn more easily than the cutter is cut to make it easy to grasp the weft, in that case, there is a problem that a specific method is not disclosed.

Meanwhile, the contents of industrial reinforcement materials including aramid fiber yarn and fusion yarn are posted. In this case, the fused yarn is used for bonding the warp yarn and the weft yarn, but the fused yarn has a structure in which the fused yarn is fused by heat, but the fused yarn is thinner than the aramid fiber yarn, and the warp yarn and the warp yarn or the weft yarn adjacent to each other by the fused yarn. There is a problem in that the bonding strength is lowered because the portion between the weft to combine the thickness of the fusion yarn.

A plurality of healds 131 are also provided along the direction of the inclination 10, and the healds 131 open the inclination 10 by vertical movement of the heald.

In addition, the weaving machine 133 of the weaving unit 130 performs a function of grabbing the weft and passing through the inclined 10 opened.

The pulling unit 140 performs a function of pulling the woven fabric 30 woven through the guide structure 143 by a predetermined length unit. To this end, the pooling part 140 includes a pair of first and second nip rollers 141 and 142 which are positioned to rotate up and down, and one first nip roller 141 has a second second nip roller ( It is desirable to contact or separate 142).

The heating unit 150 heats the woven fabric 30 to integrate the warp yarn 10 and the weft yarn of the woven fabric 30 by fusion of the low melting fiber fibers 12 and 13. To this end, the heating unit 150 is composed of first and second heating rollers (151, 152) positioned up and down. The first and second heating rollers 151 and 152 are heated by a heater (not shown) installed therein. According to the type of heat deformation resin, the first and second heating rollers 151 and 152 have an exothermic temperature according to the fusion temperature of the low melting fiber yarn 13 applied to the warp yarn 10 or the weft yarn. The heater may be an electric heater.

When the woven fabric 30 passes through the pooling unit 140 and the heating unit 150, the fabrication of the asymmetric fabric 40 of the structure in which the warp 10 and the weft yarn are integrated is completed. As described above, the weaving unit 130 may weave both the structure of the balance fabric and the structure of the asymmetric fabric by a positioner (not shown). Therefore, the weaving system according to an embodiment of the present invention can basically produce asymmetrical fabric 40 as well as a balanced fabric.

Finally, the winding unit 160 is wound (winding, winding, etc.) of the manufactured asymmetrical fabric 40 to the winding roller 161, the winding roller 161 is configured to rotate.

2 is a flow chart showing a manufacturing process of the asymmetric fabric according to an embodiment of the present invention. Referring to Figure 2, the manufacturing process of the asymmetrical fabric, the warp and weft supply step (S210), opening, engraving and cutting step (S222), weft positioning step (S230), pooling step (S240), asymmetric fabric manufacturing step ( S250), the winding step (S260) and the like.

First, the inclined and weft supply step (S210) is to supply the weft to be arranged side by side, and the weft perpendicular to the inclination, the inclination 10 is to apply a reinforcing fiber, low melting point fiber yarn, binder yarn, The weft is selected from reinforcing fibers and spreading reinforcing fibers. Since the type of warp and weft has been described in detail in the warp and weft of the asymmetrical fabric, a detailed description will be omitted.

On the other hand, the inclined reinforcing fibers are located side by side in the longitudinal width direction, the low melting point fiber yarn 12 and the binder yarn 13 is located on the most both parts (the best side), that is, the edge portion (selvedge) along the longitudinal direction. Many are arranged. The weft is to be supplied in a direction perpendicular to the longitudinal direction of the inclination, the reinforcing fibers wound on the bobbin and the reinforcing fibers are spread like a band, it is preferable to supply without twisting and twisting.

In addition, the low-melting fiber yarn applied to the weft yarn is preferably supplied along the center of the reinforcing fibers or the center of one side of the spread reinforcing fibers.

Thus, inclined and weft supply step (S210) provides a slope so that a plurality of low melting fiber yarns and binder yarns of the reinforcing fibers arranged side by side and the reinforcing fibers are arranged in a number. Feed the weft in the vertical direction with respect to the warp, but the weft feeds the reinforcing fibers or the spread reinforcing fibers, or the low melting fiber yarns are located along the center (vertical width center) of the reinforcing fibers or the spreading reinforcing fibers. Overlapping supplies.

Next, the opening, engraving and cutting step (S220) is a step of opening the inclined up and down, and infiltrating the weft between the opening inclination, the inclination supplied in the inclination and weft supply step (S210) is respectively heald ( In the state of being fitted to the 131, the inclined neighboring inclination is positioned up and down with each other by the vertical movement of the seed light 131, the inclination is a shedding motion (shedding motion).

Then, the weft is in between the opening inclined through the weft, the weft yarn is moved in the vertical direction of the longitudinal direction of the warp and passes through all the warp, the weft is a somewhat wider reinforcing fiber or spread reinforcing fiber. Therefore, it is preferable to use a gripper (a gripper cylinder, a finger gripper cylinder) that can move while holding the width of the reinforcing fiber or the spreaded reinforcing fiber completely, rather than applying a normal shuttle to insert the weft thread. . After weft yarns are inclined between the warp yarns, the weft yarns are cut at a position before the weft yarns are inclined to separate the weft weft yarns.

Next, the weft positioning step (S230), weaving the woven fabric by placing the weft in a desired position in accordance with the structure of the designed asymmetrical fabric, in this step there are a body needle method and a grip and drill method of positioning the weft yarn . Body acupuncture is a method of positioning by moving the inlet and the cut weft to the desired position to the desired position in a state in which all the opening inclination is aligned in parallel. In addition, the grip and drill method is to grasp both sides of the cut wefts while maintaining the inclined opening, and to move to a desired position to position the wefts. A gripper (gripper cylinder) is applied as a means for holding the cut wefts. .

Meanwhile, in the positioning method of the weft yarn, the body needle method is applied when the weft yarn is used as the reinforcing fiber, and the grip and drill method can be applied to both the reinforcing fiber and the spread reinforcing fiber, in particular, the grip and drill method Since the upper mouth and the cut weft are held and placed in a desired position, the shape of the reinforcing fiber can be maintained in the width direction unlike the method of directly hitting the weft by the body needle method, so that the fiber (filament) is stretched like the stretched reinforcing fiber. There is a feature that can be positioned while maintaining the shape of the weft of the state, it takes a little longer than the body needle, in the case of reinforcing fibers it is preferable to use the body needle method.

Thus, the weft positioning step (S230) completes the weft positioning by placing the weft cut in the indentation into the position where the weft is designed by the body needle method or the grip and drill method. In the weft positioning step (S230), the weft fabric is formed by combining the warp yarn with the warp yarn, and this does not determine the spacing between neighboring weft yarns, and the spacing between the weft yarns in the next pulling step (S240). Is determined.

Next, the pulling step (S240) is to pull the warp yarn, that is, the woven fabric combined with the weft yarn, the pulling distance is pulled to have a distance between the weft yarn of the designed asymmetrical fabric, in this pulling step the weft yarn is positioned Hold it in the vertical direction and pull it evenly. For example, a certain length is pulled out while passing the woven fabric between the first and second nip rollers 141 and 142, which are positioned up and down.

On the other hand, the degree of pulling the inclination in the pulling step (S240) is preferably the same as the speed of winding the asymmetric fabric manufactured in the winding step (S260), which is the last step, the gap between the weft yarn is determined by this pulling step (S240). .

Then, the bonding step (S250) is a step of manufacturing asymmetrical fabric integrally inclined and weft by applying heat and pressure, the warp yarn combined with the weft is a heat and pressure is applied while melting the low melting point fibers of the edge of the weft yarn together with the weaving yarn Secure both sides.

In addition, when the weft yarn includes a low melting point fiber yarn, the low melting point fiber yarn of the weft yarn is applied to heat and pressure to integrate with the warp, the position in which the weft yarn is indented by this bonding step (S250). On the other hand, in the bonding step (S250) it is necessary to apply a pressure that can be combined with the heat and the inclination to melt and melt the low-melting-fiber yarn, for example, the first and second heating roller which is located up and down to generate heat 151, 152 are configured. When the woven fabric (30 in FIG. 1) is passed between the first and second heating rollers 151 and 152 which are turned against each other, an asymmetrical fabric in which warp and weft yarns are integrated by low melting fiber yarns is applied by applying heat and pressure.

Finally, the winding step (S260) is a step of winding the manufactured asymmetrical fabric on a paper tube or roll, winding the asymmetrical fabric by an appropriate length, cutting to complete the production of the asymmetrical fabric.

Thus, in the manufacturing method of the asymmetrical fabric according to an embodiment of the present invention, inclined and weft supply step (S210), opening, engraving and cutting step (S220), weft positioning step (S230), pooling step (S240), bonding step (S250), the winding step (S260) is repeatedly arranged a plurality of low melting point fiber yarns and binder yarns on both sides of the plurality of reinforcing fibers arranged in a row. In addition, reinforcing fibers or spread reinforcing fibers enter into the weft yarn, but they are engraved and cut by the body needle method or the grip and drill method so that the ratio of the number of strands of the weft to the warp yarn is low, and the low melting fiber yarn is integrated by heat and pressure. The manufacturing of the asymmetrical fabric is completed by the step of winding and winding.
