Is widely used as reinforcing materials, anticorrosion, heat preservation, fireproof and flame-retardant materials, waterproof materials and the like of glass fiber reinforced plastic base cloth and engineering plastics. Such as ship body, car body, swimming pool, furniture and glass fibre reinforced plastic pipe.

The warp-knitted unidirectional fabric has high strength, but the cost is relatively high, and because the cloth surface of the stitch-bonded structure is not smooth enough, after the woven unidirectional fabric is structurally adjusted, the yarns are straightened and arranged in parallel, and the strength and the rigidity of the fiber can be fully exerted in the composite material, thereby reducing the material consumption and the cost; the warp and weft yarns of the common fabric are wavy, and the mechanical property contribution of the common fabric is only about 50 percent.

In the chinese utility model patent publication No. CN202193914U, a glass fiber woven unidirectional fabric is disclosed, which is woven by warp yarns and weft yarns, the weft yarns are made of 1200tex-2400tex untwisted glass fiber roving, the warp yarns are made of 34tex-68tex untwisted glass fiber spun yarn, the warp yarns are woven on a rapier loom by adopting 4/4 twill weave, the warp yarns are wound on the weft yarns in an S-shaped manner, and the distance between the warp yarns is 4 weft yarns. The method is mainly used for composite materials with unidirectional increase. However, the polyester fiber with fine fineness used in the glass fiber woven unidirectional fabric is not suitable for scenes with high requirements on the weft-wise strength because the weft-wise strength is small due to the fact that the straightening degree of the glass fiber is guaranteed.
