Description

Technical Field

[0001] The utility model relates to the field of textiles, and more particularly to a composite knitted fabric. Background Art

[0002] Composite knitted fabric refers to a fabric formed by combining multiple layers of knitted fabric. By combining different functional layers together, the overall fabric has stronger functionality.

[0003] Because the thickness of composite knitted fabric is relatively thicker than that of single-layer fabric, composite knitted fabric is also used in curtains. Through the combination of polyester layer and cotton layer, the curtain fabric has better air permeability while taking into account the overall wrinkle resistance. The polyester layer is arranged on the outside of the fabric, which makes the curtain fabric have better wear resistance. However, when the surrounding environment is relatively dry, the fabric contains less moisture and the anti-static ability of the polyester layer is weak, which leads to a greater possibility of static electricity on the polyester layer.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a composite knitted fabric.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a composite knitted fabric, comprising an inner layer and an outer layer, the inner layer is knitted with cotton yarn, the outer layer is woven with polyester yarn to form a plain weft stitch, the outer layer comprises a breathable portion and a conductive portion, the plain weft stitch is located on the coil horizontal row of the conductive portion and conductive colored yarn is added, the plain weft stitch is located at the position of the breathable portion and is woven to form a plurality of single-needle single-row tuck loops, the conductive portion is further provided with a plurality of ridges on the side facing away from the inner layer, the ridges are woven with wear-resistant yarn, and the wear-resistant yarn contains metal wire.

[0007] The utility model is further configured as follows: the wear-resistant yarn includes a yarn core and a winding yarn wound around the yarn core; the metal wire is also wound around the yarn core; the diameter of the metal wire is greater than the diameter of the winding yarn; and the winding yarn is twisted from nylon yarn.

[0008] The utility model is further configured as follows: the yarn core is formed by twisting polyester fibers.

[0009] The utility model is further configured as follows: conductive yarns are padded on the longitudinal rows of the weft plain stitch structure.

[0010] The utility model is further configured as follows: the conductive yarn and the conductive colored yarn are both twisted with silver fibers.

[0011] The present invention is further configured such that: the thickness of the inner layer is greater than the thickness of the outer layer.

[0012] In summary, the utility model has the following beneficial effects: when the outer layer rubs against an external object, the convex strips protrude from the outer layer, and thus the position where the outer layer rubs against the external object is concentrated on the convex strips. The wear-resistant yarn contains metal wires, so the wear-resistant yarn also has good conductivity and can quickly conduct the static electricity concentrated at the convex strip position to the conductive part. The static electricity is conducted along the conductive part, so that the generated static electricity is not easily accumulated in one place, thereby ensuring the overall anti-static effect of the fabric.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] A composite knitted fabric, such as Figure 1 and Figure 2As shown, it includes an inner layer 1 and an outer layer 2, the inner layer 1 is knitted with cotton yarn, the outer layer 2 is woven with polyester yarn 4 to form a plain weft structure, the outer layer 2 includes a breathable portion and a conductive portion, the breathable portion and the conductive portion are alternately arranged on the outer layer 2, and the area of ​​the breathable portion is larger than the area of ​​the conductive portion. In this embodiment, the area of ​​the breathable portion on the outer layer 2 is four times that of the conductive portion, the plain weft structure is located on the coil row of the conductive portion and a conductive colored yarn 5 is added, and the plain weft structure is located at the position of the breathable portion and woven to form a plurality of single needles Single row of tuck loops, a number of ridges 3 are provided on the side of the conductive part facing away from the inner layer 1. The ridges 3 are woven from wear-resistant yarns containing metal wires 6. After the wear-resistant yarns are fed into an embroidery machine, the embroidery machine is used to weave the ridges 3 on the outer layer 2. The ridges 3 protrude from the outer layer 2, making the side of the outer layer 2 facing the room uneven, so that sunlight is easily diffused when it reaches the outer layer 2. In addition, the wear-resistant yarn contains metal wires 6, which can increase the reflective effect of the ridges 3, thereby ensuring the integrity of the fabric. The shading performance of the body, when the outer layer 2 rubs against the external object, the ridges 3 protrude from the outer layer 2, so the position where the outer layer 2 rubs against the external object is concentrated on the ridges 3. The wear-resistant yarn contains metal wire 6, so the wear-resistant yarn also has good conductivity, which can quickly conduct the static electricity concentrated at the ridge 3 position to the conductive part, and the static electricity is conducted along the conductive part, so that the generated static electricity is not easy to accumulate in one place, thereby ensuring the overall anti-static effect of the fabric. The setting of the conductive color yarn 5, on the one hand, ensures the ability of the conductive part to conduct static electricity, and on the other hand, increases the weaving density of the outer layer 2 at the conductive part. The high weaving density of the conductive part makes the ridges 3 woven in the outer layer 2 stronger. At the same time, the conductive color yarn 5 makes the color of the conductive part different from the color of the breathable part, which is convenient for people to distinguish between the conductive part and the breathable part. The weaving density of the single-needle single-row loop position on the breathable part is low, which ensures the breathability of the breathable part. The inner layer 1 itself is knitted with cotton yarn and has good breathability, thereby improving the overall breathability of the fabric.

[0019] like Figure 1 and Figure 2 As shown, the thickness of the inner layer 1 is greater than that of the outer layer 2. In this embodiment, the thickness of the inner layer 1 is twice that of the outer layer 2. This arrangement ensures the overall air permeability of the fabric. Several longitudinal rows of coils of the weft plain needle structure are padded with conductive yarn 9. The conductive yarn 9 and the conductive colored yarn 5 are twisted with silver fibers. The silver fibers have good conductivity and certain antibacterial properties. While ensuring the conductive performance of the conductive yarn 9, the conductive yarn 9 also has certain antibacterial properties. By arranging the conductive yarn 9, the static electricity of the conductive part can be simultaneously conducted to other positions of the outer layer 2, further improving the overall antistatic ability of the fabric.

[0020] like Figure 3As shown, the wear-resistant yarn includes a yarn core 7 and a winding yarn 8 wound around the yarn core 7. The metal wire 6 is also wound around the yarn core 7. The winding yarn 8 is twisted with cotton fiber. The diameter of the metal wire 6 is larger than the diameter of the winding yarn 8. The metal wire 6 has good wear resistance. This arrangement ensures the overall wear resistance of the wear-resistant yarn. The cotton fiber has moisturizing ability, which further reduces the possibility of static electricity generated at the position of the convex strip 3. The yarn core 7 is twisted with polyester fiber. The polyester fiber has high strength, which ensures the overall strength of the wear-resistant yarn.
