Abstract
Description
Technical Field
[0001] This utility model relates to the textile field, and more specifically, to a knitted fabric. Background Technology
[0002] Knitted fabric refers to fabric woven through warp or weft knitting. Knitted fabric is often used in the manufacture of clothing, home textiles, and other products. Clothing and home textile products are often seasonal. In cold seasons, users will need clothing and home textiles with good insulation, thus requiring knitted fabric with good insulation. Existing knitted fabrics generally form a pile structure on the surface of the fabric by brushing or other processes, which reduces heat exchange between the two sides of the fabric through a slow-flowing air layer. However, during use, the pile structure is prone to pilling under external influences, affecting the insulation effect. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a knitted fabric.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a knitted fabric, including an outer layer, an inner layer and an intermediate layer located between the outer layer and the inner layer, the intermediate layer including a first yarn and a second yarn, the intermediate layer being divided into a longitudinal stretching portion and a transverse stretching portion, the transverse stretching portion being arranged in a longitudinal linear array, and the longitudinal stretching portion being arranged in a transverse linear array between adjacent transverse stretching portions, and a gap being provided between adjacent longitudinal stretching portions.
[0005] The present invention is further configured such that: both the first yarn and the second yarn form a heavy warp-knitted chain structure at the transverse stretching portion.
[0006] The present invention is further configured such that: the padding number of the first yarn is 2-0 / 2-0 / 2-0 / 1-2 / 2-2 / 2-2 / 2-3 / / one thread and one empty, and the padding number of the second yarn is 3-1 / 3-1 / 3-1 / 2-1 / 2-1 / 2-1 / 2-1 / 2-1 / / one thread and one empty.
[0007] The present invention is further configured such that both the outer and inner layers are woven from thermal insulation yarns into a double rib structure.
[0008] The present invention is further configured such that the heat-insulating yarn is composed of polyester fiber bundles and cotton fiber bundles wrapped around the polyester fiber bundles.
[0009] The present invention is further configured such that: both the first yarn and the second yarn are made of twisted polyester fiber bundles.
[0010] In summary, this invention has the following beneficial effects: the cavity structure formed between the outer and inner layers through pores in the middle layer creates a slow-flowing air layer, reducing heat exchange between the two sides of the knitted fabric and improving its warmth retention. The pores are formed through the weaving structure of the first and second yarns, which has higher stability than the mesh formed by punching and cutting, ensuring the structural stability of the middle layer. The cotton fiber bundles have good warmth retention, and combined with the double rib structure, the warmth retention of the knitted fabric is further improved. Attached Figure Description

[0014] Figure 4 This is a diagram of the outer layer's organizational structure.
[0015] In the diagram: 1. Outer layer; 2. Middle layer; 3. Inner layer. Detailed Implementation
[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0017] Example: A knitted fabric, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes an outer layer 1, an inner layer 3, and an intermediate layer 2 located between the outer layer 1 and the inner layer 3. The intermediate layer 2 includes a first yarn and a second yarn. The intermediate layer 2 is divided into a longitudinal stretching section and a transverse stretching section. The transverse stretching section is arranged in a longitudinal linear array. Between adjacent transverse stretching sections, the longitudinal stretching section is arranged in a transverse linear array. A hole is provided between adjacent longitudinal stretching sections.
[0018] Specifically, the outer layer 1, the middle layer 2, and the inner layer 3 are sewn together with stitches. The middle layer 2 has pores that form a cavity structure between the outer layer 1 and the inner layer 3, creating a slow-flowing air layer. This reduces heat exchange between the two sides of the knitted fabric and improves its warmth retention. The pores are woven together using the first and second yarns, which provides greater stability compared to meshes formed by punching and cutting. This ensures the structural stability of the middle layer 2 and thus guarantees the lifespan of the knitted fabric.
[0019] like Figure 2 , Figure 3As shown, both the first yarn and the second yarn form a double warp-knitted chain structure at the transverse stretching section. The padding yarn number of the first yarn is 2-0 / 2-0 / 2-0 / 1-2 / 2-2 / 2-2 / 2-3 / / one thread and one gap, and the padding yarn number of the second yarn is 3-1 / 3-1 / 3-1 / 2-1 / 2-1 / 2-1 / 2-1 / / one thread and one gap. Both the first yarn and the second yarn are made of twisted polyester fiber bundles.
[0020] Specifically, in the transverse direction, the first yarn and the second yarn ensure the extensibility of the intermediate layer 2 through interconnected warp loops. Both the first yarn and the second yarn are made of three strands of polyester fiber bundles twisted together. In the longitudinal stretching section, the first yarn forms a sparse structure, and the second yarn forms a closed braided structure. In the longitudinal direction, the good extensibility of the polyester fiber bundles themselves, combined with the sparse structure and the braided structure, ensures the extensibility of the intermediate layer 2 in the longitudinal direction, and avoids the intermediate layer 2 from being damaged due to excessive deformation, thus preventing the structural stability of the intermediate layer 2 from being compromised.
[0021] like Figure 4 As shown, both outer layer 1 and inner layer 3 are woven into a double rib structure using thermal insulation yarn. The thermal insulation yarn consists of polyester fiber bundles and cotton fiber bundles wrapped around the polyester fiber bundles. Specifically, the weaving structure of outer layer 1 is the same as that of inner layer 3. The thermal insulation yarn is formed by three cotton fiber bundles wrapped around a single polyester fiber bundle. The cotton fiber bundles have good thermal insulation properties, and combined with the double rib structure, the thermal insulation of the knitted fabric is further improved.

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.
