However, in the usual leno weave structure, when two sets of warp are entangled, the warp bends, so that the excellent properties inherent in the reinforcing fiber, such as high strength and high elastic modulus, cannot be fully utilized. was there. In addition, since the leno fabric easily causes misalignment, the arrangement of the reinforcing fibers is easily disturbed, and in order to prevent this misalignment, a step of further processing the resin after producing the fabric must be provided. .

も良い。A thermoplastic polymer yarn is used as one of the warp yarns, and a high elasticity yarn is used as the remaining warp and weft, so that the amount of the thermoplastic polymer yarn to be sent out is larger than the amount of the high elasticity yarn to be sent out. Normal leno weaving is performed such that the warp yarns are on the same side of the fabric. Alternatively, two thermoplastic polymer yarns may be used to form a three-ply weave.

方法等により行う事ができる。[0010] As means for increasing the feeding amount, a warp beam of a high elasticity yarn and a warp beam of a thermoplastic polymer yarn are separately prepared to form a double beam, and the beam of the high elasticity yarn is used as the weft density (number of shots). While the positive feed is set to the amount specified by, the beam of thermoplastic polymer yarn is sent at a low tension by negative feed to increase the feed amount of the high elastic yarn. From the bobbin of high elasticity yarn and thermoplastic polymer yarn,
When supplying warp directly to the loom, only the high-elasticity yarn is sent through a positively driven roll and adjusted to the amount corresponding to the weft density, whereas the thermoplastic polymer yarn is sent to the loom with free tension, so that How to increase
Alternatively, the high elasticity yarn, which is a warp, can maintain its linearity, that is, the thermoplastic polymer yarns can rotate around the pair of high elasticity yarns while gripping the weft by an amount necessary to rotate the high elasticity yarns. It can be carried out by a method in which each yarn is positively fed so as to feed many yarns.

必要がある。The delivery amount of the thermoplastic polymer yarn is:
It is necessary to increase in proportion to the cross-sectional area of each warp and weft to be used and the density of the weft, but if it is increased more than necessary, the gripping force at the intersection of the warp and the weft decreases, and misalignment is likely to occur. Therefore, the handleability of the fabric is deteriorated.
Therefore, it is necessary to adjust the feed amount of the thermoplastic polymer yarn in accordance with the handling property and the degree of linearity of the reinforcing fiber.
