Description

Technical Field

[0001] This utility model relates to the textile field, and more specifically, to an antistatic knitted fabric. Background Technology

[0002] Knitted fabric is a type of textile made using knitting techniques. Because knitted fabric is formed by continuous loops interlocking, it has the characteristics of good elasticity, softness, breathability, and strong fit.

[0003] To ensure the overall strength and lifespan of knitted fabrics, some knitted fabrics are made of polyester fibers, which gives the knitted fabrics high overall strength. However, polyester fibers have relatively weak antistatic ability, especially in dry environments, where static electricity accumulated on the knitted fabric is difficult to dissipate, resulting in static electricity buildup.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an antistatic knitted fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an antistatic knitted fabric, comprising a base layer, the base layer comprising rib sections and plain knit sections arranged alternately in the transverse direction, the plain knit sections having a plurality of ventilation holes woven in them, conductive yarn passing through the base layer in the transverse direction, the conductive yarn being woven in the base layer to form fixed loops, transverse floats and oblique floats, the transverse floats being located on the plain knit sections and crossing the longitudinal row of the loops where the ventilation holes are located, the oblique floats being located on the rib sections and the oblique floats crossing at least two row spacings in the longitudinal direction, and antistatic yarn being longitudinally padded on the base layer.

[0007] The present invention is further configured such that: the flat needle part consists only of the front coil longitudinal row, the rib part consists of the front coil longitudinal row and the reverse coil longitudinal row, the fixed coil is sleeved on the front coil longitudinal row, and the antistatic yarn is also padded on the front coil longitudinal row.

[0008] The present invention is further configured such that: a plurality of single-needle single-row tufts are knitted on the flat needle section, the vent hole is located at the position of the single-needle single-row tuft, and the horizontal float is located between two adjacent vent holes.

[0009] The present invention is further configured such that: the base layer is woven from polyester yarn, and the conductive yarn is twisted from silver fiber.

[0010] The present invention is further configured such that: the antistatic yarn includes a yarn core and a winding yarn wrapped around the yarn core, the winding yarn is made of silver fiber twisted together, and the yarn core is made of high-elastic polyester yarn twisted together.

[0011] The present invention is further configured such that the cross-section of the high-elastic polyester yarn is arranged in a ring shape.

[0012] In summary, this utility model has the following beneficial effects:

[0013] Conductive yarn has electrical conductivity, which allows it to conduct the charge accumulated on the base layer laterally. Antistatic yarn also has antistatic properties, which allows it to conduct the charge longitudinally, making it less likely for the charge to concentrate on the base layer and reducing the occurrence of static electricity. By setting vent holes, the breathability of the base layer can be guaranteed. The horizontal floats are short and vertical, which can limit the deformation of the vent holes and make them less prone to deformation. The diagonal floats are relatively long and diagonal, so that the location of the diagonal floats still has a certain amount of deformation, ensuring the overall extensibility of the base layer.

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

[0018] Antistatic knitted fabrics, such as Figure 1 and Figure 2As shown, the system includes a base layer, which comprises alternating rib sections 1 and plain needle sections 2 arranged laterally. Several ventilation holes 3 are woven into the plain needle sections 2. Conductive yarn 4 passes laterally through the base layer, forming fixed loops, horizontal floats 5, and diagonal floats 6. The horizontal floats 5 are located on the plain needle sections 2 and cross the longitudinal row of the loops containing the ventilation holes 3, spanning one stitch length. The diagonal floats 6 are located on the rib sections 1 and cross at least two row lengths longitudinally. Antistatic yarn 7 is also longitudinally padded on the base layer. The base layer is woven from polyester yarn 8, which has high structural strength and long lifespan, thus ensuring the base layer's stability. In terms of overall lifespan, the conductive yarn 4 has electrical conductivity, which allows it to conduct the charge accumulated on the base layer laterally. The antistatic yarn 7 also has antistatic properties, which allows it to conduct the charge longitudinally, making it less likely for the charge to concentrate on the base layer and reducing the occurrence of static electricity. By setting the ventilation holes 3, the breathability requirements of the base layer can be guaranteed. The transverse float 5 is short and vertical, which can limit the deformation of the ventilation hole 3 and make it less likely for the ventilation hole 3 to deform. The oblique float 6 is relatively long and oblique, so that the location of the oblique float 6 still has a certain deformation, ensuring the overall extensibility of the base layer.

[0019] like Figure 1 and Figure 2 As shown, the plain knit section 2 consists only of the front loop warp, while the rib section 1 consists of both the front and back loop warp. The plain knit section 2 is a weft plain knit structure woven from polyester yarn 8, and the rib section 1 is a rib structure woven from polyester yarn 8. Compared to the weft plain knit structure, the rib structure has better stretchability in the transverse direction. Therefore, the deformation of the base layer tends to concentrate on the rib section 1, while the ventilation holes 3 and the transverse floats 5 are both on the plain knit section 2. This results in a smaller deformation at the ventilation hole 3, further ensuring the stability of the ventilation hole 3. The fixed coil is sleeved on the front coil longitudinal row, and the antistatic yarn 7 is also padded on the front coil longitudinal row, so that the fixed coil positions of the antistatic yarn 7 and the conductive yarn 4 are alternated. Several single-needle single-row tufted loops are woven on the flat needle part 2. The vent hole 3 is located at the single-needle single-row tufted loop position. The transverse float 5 is located between two adjacent vent holes 3. This setting makes it difficult for the transverse float 5 to affect the air permeability of the vent hole 3. Moreover, the vent hole 3 is formed by the structure woven by the base layer itself, thereby ensuring the stability of the vent hole 3 structure.

[0020] like Figure 1 and Figure 2As shown, the conductive yarn 4 is made of silver fiber twisted together. Silver fiber has good conductivity, which can ensure the overall conductivity of the conductive yarn 4. The antistatic yarn 7 includes a yarn core 9 and a winding yarn 10 wrapped around the yarn core 9. The winding yarn 10 is made of silver fiber twisted together. The yarn core 9 is made of high-elastic polyester yarn twisted together. High-elastic polyester yarn has the characteristics of good elasticity and good extensibility, so that the base layer still has a certain extensibility in the longitudinal direction. The winding yarn 10 is made of silver fiber twisted together, which makes the surface of the antistatic yarn 7 have excellent conductivity and reduces the generation of static electricity on the base layer. The cross-section of the high-elastic polyester yarn is arranged in a ring shape. The interior of the high-elastic polyester yarn is hollow, which ensures the overall softness of the antistatic yarn 7.

[0021] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
