(Industrial Application Field) The present invention relates to an elastic warp knitted fabric, particularly an elastic warp knitted fabric used as an integrally molded fabric. (Prior art) One-piece products used for automobile interior materials, etc. are obtained by laminating an integrally molded fabric onto a plastic sheet to form a composite sheet, which is then molded into the desired shape at once by thermoforming or vacuum forming. It will be done. As a fabric for integral molding, for example, as described in JP-A-58-49237, an elastic warp-knitted fabric using non-stretch fiber yarns in the front reed and stretchable fiber yarns in the rear reed is known. It is being However, the elastic warp knitted fabric is made by knitting a conventionally known two-way tricot knitting structure using conventionally known synthetic fiber filament yarns and polyurethane elastic yarns, and when knitting, the gauge of the knitting machine is adjusted. It is coarser than before, and the weaving density is slightly coarser,
In terms of finishing density, it was knitted with a coarse course density and a dense wale density, with a vertical and horizontal elongation of just over 200%, so it was a tricot knit for swimsuits or foundations, which was conventionally known. The physical properties were not much different from those of the ground, making it unsuitable for integral molding. Since the conventional elastic warp knitted fabric has a rough knitting density, the degree of drawing (the value given by H/D in a cylindrical molded hole with a diameter D and a depth H) is particularly low.
When the development magnification is 0.5 or more and the development magnification is 300% or more, the stitches themselves become coarse and there is a drawback that the density change is large. Furthermore, when the degree of drawing is close to 1.0, the fabric stress of the elastic warp knitted fabric increases to 30 to 40 kg, making it difficult to form the fabric.Also, even if forming is possible, the elastic recovery force of the fabric will affect the areas with a large degree of drawing. This resulted in the disadvantage that the fabric was prone to lifting and peeling. In addition, if the desired appearance of the elastic warp knitted fabric is thick, such as velvet-like or pile-like, and a long pile after raising is required, a warp knitted fabric made of two reeds is not suitable. Ta. (Problems to be Solved by the Invention) The present invention can be used for integral molding that allows easy molding work and does not cause lifting or peeling of the fabric even when the degree of drawing is increased, and has elastic warp of thick fabric. The purpose is to obtain knitted fabrics. (Means for Solving the Problems) In the present invention, the synthetic fiber filament yarns arranged in the front reed have 3 to 8 stitches, and the synthetic fiber filament threads arranged in the middle reed have 2 stitches. Needle or more 3
It swings in the opposite direction to the front reed with a swing below the needle,
A warp-knitted fabric in which the elastic yarns arranged in the rear reed swing in the same direction as the front reed with two stitches, and the synthetic fiber filament yarns arranged in the front reed and the middle reed are constituted. The fiber elongation at break is 40-180%, the birefringence (△n) is 20-140×10 -3 , and the stress at 10% elongation is
0.3 to 3 g/d, and the breaking elongation of the elastic thread arranged in the rear reed is 400% or more, and the stress at 300% elongation is 10 to 3.
20g, single fiber denier 8-20 denier,
It is an elastic warp knitted fabric with a total denier of 30 to 70 deniers. Even when the degree of drawing (H/D) is close to 1.0, the fabric stress at that time must be 15 kg to improve molding workability and prevent fabric from lifting or peeling.
Below, it is preferable to use 10Kg of low stress fabric if possible.
For this purpose, it is necessary to reduce the stress in the synthetic fiber filament yarns and elastic yarns that make up the warp knitted fabric. In order to satisfy this requirement, the elongation at break of the fibers that make up the synthetic fiber filament yarn must be
40-180%, birefringence (△n) 20-140×10 -3 ,
It is necessary that the stress at 10% elongation is 0.3 to 3 g/d, and yarns having these physical properties can be obtained by high-speed spinning at a spinning speed of 2000 m/min or more. In addition, at this time, the synthetic filament yarn needs to have a large number of filaments so that the density of the stitches is not visible when viewed from the cloth surface, and the single fiber denier is 0.5 to 1.5 denier, and the total denier is 30 to 75 denier. preferable. In addition, in the case of elastic yarn, it is necessary that the elongation at break is 400% or more, and the stress at 300% elongation is 10 to 20 g. In order to reduce the stress in the elastic yarn, even if the total denier is the same, by increasing the thickness of the monofilament that makes up the yarn, the elongation of the yarn itself will increase, and
It was found that the stress at 300% elongation decreased.
As an example, Table 1 shows the results when the total denier is 40 denier.

第２表に示す性量、物性を有する編地を得た。[Table] Therefore, in order to reduce the stress of the elastic yarn, it is necessary that the single fiber denier of the elastic yarn is 8 to 20 deniers and the total denier is 30 to 70 deniers. If the total denier exceeds 70 denier, the elongation will decrease even if the single fiber denier is thickened.
It is more than 400%, but because the total denier is thick, the thread stress is high and the fabric stress is difficult to reduce.
In addition, when the total denier is less than 30 deniers, the stress on the fabric becomes extremely low, but the stress is too low during the finishing process of the fabric, especially during the napping process, which makes it easy to cause uneven naps and to ensure uniform and stable quality. It becomes difficult to obtain knitted fabrics. Examples of the synthetic fiber filament yarn used in the present invention include polyester fiber yarn, polyamide fiber yarn, polyacrylonitrile fiber yarn, and polypropylene fiber yarn, but polyester fiber yarn is preferable due to its physical properties. Examples of elastic threads include synthetic rubber-like elastic threads such as polyester elastomer elastic threads, polyamide elastomer elastic threads, polyurethane elastomer elastic threads, fluorine-based elastomer elastic threads, and polycarbonate elastomer elastic threads, but polyurethane elastomer elastic threads are particularly suitable. preferable. Examples of polyurethane elastomers include polyurethane elastomers obtained by reacting polymer diols such as polyester diols, polyether diols, and polycarbonate diols with polyisocyanates, low-molecular chain extenders, and optionally terminal cappers. Elastic yarns molded from molded polyurethane elastomers are preferred because they have excellent thermal stability. Further, the yarn may be either a covered yarn or a bare yarn, but preferably a bare yarn. The knitting structure is such that the synthetic fiber filament yarns arranged in the front reed have a swing of 3 to 8 stitches, and the synthetic fiber filament yarns arranged in the middle reed have a swing of 2 to 3 stitches. It is necessary to have a warp knitting structure in which the elastic threads arranged in the rear reed are swung in the same direction as the front reed, and the elastic yarns arranged on the rear reed are swung in the same direction as the front reed. The expansion of the stitches inevitably occurs during molding, but in order to make the density of the stitches invisible from the surface of the fabric, it is necessary that the synthetic fiber filament yarn arranged in the front reed has at least 3 stitches and no more than 8 stitches. . Further, the synthetic fiber filament yarn arranged in the reed is preferably knitted with a swing of 2 or more stitches and 3 or less stitches in order to reduce the amount of yarn to reduce costs and to provide firmness to the knitted fabric. In addition, in order to reduce damage during napping and lower costs by reducing the mixing ratio, the elastic threads arranged in the rear reed are swung between two stitches, and are swung in the opposite direction to the middle reed ( In other words, it is necessary to swing in the same direction as the front reed. If the thread arranged on the front reed is swung with less than 3 stitches, disadvantages such as the short sinker loop making it difficult to raise the yarn and the length of the raised yarn tend to occur. If more than 8 stitches are used in the reaction, the fabric will have too much weight and become thick, which will be disadvantageous in terms of cost and also have poor moldability. The obtained knitted fabric is subjected to the following steps under normal conditions: Relaxation soup presetting - napping and shearing (performed multiple times depending on the desired product) - presetting - dyeing - finishing setting. The physical properties in the present invention were measured as follows. Birefringence (Δn): Calculated using the following formula using sodium D line (wavelength 589 mμ) as a light source and arranging filaments diagonally. △n=nλ+γ/α Where, n: Number of interference fringes depending on the degree of orientation of polymer molecular chains γ: Retardation determined by Berek compensator for orientation that does not result in interference fringes λ: Wavelength of sodium D line α: Diameter of fiber Breaking elongation: According to JIS L-1070 method. Stress during elongation: Based on JIS L-1070 method. (Examples) Hereinafter, the present invention will be explained by examples, but the present invention is not restricted by these examples.

Even complex curved shapes can be molded without difficulty, and there is no distortion after molding, resulting in a beautiful product. It was a finished molded product. In addition, the stress was evenly distributed in the elongation of the curved surface area, so there was no peeling at the corners, and the hair was long after raising, resulting in a three-dimensional molded product with excellent appearance and texture. On the other hand, in the comparative example, the stress generated during molding was extremely large, and in the case of a complex curved shape, molding was difficult, and distortion occurred after molding. In addition, peeling occurred at the corner portions, resulting in a three-dimensional molded product with poor appearance and texture. (Effects of the Invention) When the elastic warp knitted fabric of the present invention is used for integral molding, the molding operation is easy, and even when the degree of drawing is increased, the fabric does not rise or peel. It was an excellent knitted fabric for integral molding. In addition, since the knitted fabric is thick, the texture and appearance after molding were excellent.
