Description

[Detailed description of the invention] [Industrial application field] The present invention relates to textiles.

[Prior Art] Generally used shuttled RtR is superior in terms of less thread breakage due to warp entanglement and the formation of woven fabrics during weaving of materials such as cotton that are prone to thread entanglement due to fluff. This is generally known. On the other hand, as a method that is excellent in terms of improving productivity, the weft insertion means uses a jet stream, a gripper, or a rapier, etc., and the weft is fixed to the side of the machine stand, and the weft is inserted from there by the weft insertion means. A shuttleless machine is known that pulls out the weft by a certain length and inserts the weft piecemeal.

[Problems to be Solved by the Invention] In the above shuttled loom and shuttleless R machine, the weft is inserted in a direction perpendicular to the warp group, and beating is performed, and the warp and weft are orthogonal to each other. The apparatus is configured to weave textiles. For this reason, there was a problem in that it was not possible to insert the weft threads diagonally with respect to the warp threads. In addition, a fabric in which the warp and weft are orthogonally woven in this way has a problem in that the tensile strength against diagonal forces is weak.

Therefore, an object of the present invention is to provide a fabric having high tensile strength against diagonal forces.

[Means for Solving the Problems] The present invention is a woven fabric in which weft yarns are woven diagonally with respect to warp yarn groups.

[Example] Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, this is a fabric C in which the weft threads are woven diagonally into the warp threads a group. An example of a method for weaving this fabric C will be described below.

In FIGS. 2 and 3, 1 is a reed that is movable back and forth on the frame (not shown) of the Is machine, and this reed 1
are disposed at an appropriate angle, for example, 45 degrees obliquely to the warp a when viewed from above, and are movable back and forth in the warp a direction using the lower end pivot 2 as a fulcrum. Further, the frame is provided with a pair of front and rear crankshafts 3.4 that rotate synchronously, the crank arm 3a of one crankshaft 3 is connected to one side of the reed 1, and the crank 7- of the other crankshaft 4 is connected to one side of the reed 1. A beam 4a is connected to the other side of the reed 1. Further, a pair of heald frames 5 and 6 are provided parallel to the reed 1 so as to be movable up and down by well-known means.

Then, shedding motion is applied to the warp threads a by the upper and lower parts of the heald frame 5.6, and the weft threads are inserted into the reed 1 by a first stage of weft insertion 8 using a shuttle, a jet stream, a gripper, a rapier, etc. in the lower part between the warp threads. Reed 1 installed in an oblique direction with weft inserted diagonally along the
The crankshaft 3.4 and crank arms 3a, 4
The fabric C is woven by moving in the direction of the warp a through the warp a to beat the weft, thereby weaving the weft in a diagonal direction with respect to the warp a.

Further, the inclination angle of the reed 1 with respect to the warp threads a may be selected as appropriate. For example, by making the position of the connecting part between the reed 1 and the crank arms 3a, 4a and the position of the lower end pivot 2 adjustable, the reed 1 can be adjusted with a feed screw or the like. The inclination angle of the weft threads can be freely changed, and the oblique angle of the weft threads with respect to the warp threads a can be appropriately selected.

The fabric C thus woven is woven with the weft threads obliquely intersecting the warp threads a at a constant angle, as shown in FIG. Therefore, in addition to warp and weft threads that are orthogonal to each other, the weft threads can be easily woven diagonally without the need for complicated devices or operations for inserting diagonal threads into the fabric. In addition, this fabric C has the weft threads diagonally woven with respect to the warp a group, so it has excellent tensile strength in the diagonal direction of 4 degrees, and can be used for a variety of purposes.For example, the fabric C can be used as a grindstone cloth. As shown in Figure 5, by stacking a large number of carbon random, alundum, and flandom abrasive grains so that their weaving directions are shifted from each other, and adding a binder to the abrasive grains, we manufacture the whetstone d. , a grinding wheel d having threads built in in the overall reflection direction and excellent in strength against diagonal forces can be obtained.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the scope of the gist of the present invention. For example, the means for weaving the weft threads diagonally and the inclination angle of the weft threads may be appropriately selected.

[Effects of the Invention] The present invention can provide a fabric in which the weft threads are woven diagonally with respect to the shuttle threads, and which has excellent tensile strength in the diagonal direction.
