[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Embodiment 1

[0021] Combination Figure 1 and Figure 2 , this embodiment is described in detail. The elastic warp knitted jacquard composite fabric involved in this embodiment includes a composite warp knitted jacquard elastic fabric layer 1 and an antibacterial warp knitted elastic fabric layer 2. Specifically, the composite fabric is composited by a hot melt adhesive mesh.

[0022] The warp knitted jacquard elastic fabric layer 1 is woven by a warp knitted jacquard jacquard warp knitting machine, and includes a ground structure and a jacquard pattern. The yarn used in the ground structure is a first spandex core-spun yarn, and the yarn used in the jacquard pattern is a second spandex core-spun yarn. The first spandex core-spun yarn includes spandex and a first nylon multifilament wrapped on the outside of the spandex, and the second spandex core-spun yarn includes spandex and a second nylon multifilament wrapped on the outside of the spandex; the first nylon multifilament and the second nylon multifilament have different colors, and the cross section of each monofilament includes a fiber body 11 in the shape of a straight line and protrusions 12 symmetrically arranged on both sides of the fiber body, and the protrusions 12 are perpendicular to the fiber body 11.

[0023] Further, the ground fabric is woven by double warp plain fabric or mesh fabric. In this embodiment, double warp plain fabric is selected.

[0024] The first spandex core-spun yarn and the second spandex core-spun yarn used make the warp knitted elastic fabric layer 1 have good elasticity. The first nylon multifilament in the first spandex core-spun yarn and the second nylon multifilament in the second spandex core-spun yarn have different colors, so that the jacquard pattern and the ground weave have different colors, making the jacquard pattern more obvious. The fineness of the first nylon multifilament and the second nylon multifilament is 75D / 48F. The fineness of the spandex used is 70D.

[0025] The jacquard pattern is located on the side away from the antibacterial warp knitted fabric layer 2; the warp knitted jacquard elastic fabric layer 1 has a fluff layer 3 formed by raising the side of the warp knitted fabric layer 2. The fluff layer 3 is formed by raising the first nylon multifilament and the second nylon multifilament. The cross-sectional shape is a slender flat structure, which is very similar to the shape of a caterpillar and has good uprightness, so that the fiber can stand up quickly after bending. The fluff in the fluff layer 3 can stand up quickly after lodging.

[0026] The antibacterial warp knitted elastic fabric layer 2 is knitted by a third spandex core-spun yarn using a warp knitting device, wherein the third spandex core-spun yarn includes spandex and antibacterial nylon filaments coated on the outside of the spandex. The fineness of the antibacterial nylon filaments used is 40D / 36F.

[0027] Embodiment 2

[0028] Combination Figure 3 , this embodiment is described in detail. The elastic warp knitted jacquard composite fabric involved in this embodiment is different from that in the first embodiment in that: the third spandex core-spun yarn further includes graphene-modified nylon filaments, and the graphene-modified nylon filaments are arranged in parallel with the antibacterial nylon filaments.

[0029] Another difference from the first embodiment is that a heat-insulating warp knitted elastic fabric layer 4 is further provided between the warp knitted jacquard elastic fabric layer 1 and the antibacterial warp knitted elastic fabric layer 2; the heat-insulating warp knitted elastic fabric layer 4 is woven by a warp knitting device with a fourth spandex core-spun yarn, and the fourth spandex core-spun yarn includes spandex and an aerogel fiber yarn wrapped around the outside of the spandex. The outside of the aerogel fiber yarn is wrapped with a hygroscopic heat-generating fiber yarn. The use of aerogel fiber yarn and hygroscopic heat-generating fiber yarn can improve the warmth-keeping effect of the composite fabric.
