Description

Technical Field

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

[0002] Thermal knitted fabric is a functional textile that effectively reduces heat loss and improves insulation performance through special weaving structures or material combinations. Its insulation performance usually depends on factors such as the thermal resistance of the fiber material, the air retention capacity of the fabric structure, and the overall thickness. Therefore, some thermal knitted fabrics use multi-layer composite structures to form insulation cavities and increase the overall thickness. However, when multiple layers of fabric are laminated by bonding or hot pressing, the insulation cavity (air layer) in the middle is prone to collapse and displacement after washing or long-term use, resulting in a decrease in insulation performance. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a warm knitted fabric.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a warm knitted fabric, comprising an outer layer and an inner layer sewn together, wherein the outer layer is provided with a plurality of longitudinal ridges and transverse ridges on the side near the inner layer, the transverse ridges are linearly arranged in the longitudinal direction, and the longitudinal ridges are arranged in a transverse linear arrangement between adjacent transverse ridges; the inner layer is provided with a plurality of longitudinal ridges arranged in a transverse linear arrangement on the side near the outer layer, wherein the width of the longitudinal ridges is greater than the spacing of the longitudinal ridges.

[0005] The present invention is further configured such that: the inner layer is woven from a first yarn and a second yarn, the first yarn forming a full-width warp plain weave, the second yarn forming a warp plain weave, and the density of the second yarn being less than the density of the first yarn.

[0006] The present invention is further configured such that: the padding number of the first yarn is 1-2 / 1-0 / / full thread, and the padding number of the second yarn is 0-1 / 1-2 / / three thread and one empty thread.

[0007] The present invention is further configured such that: the outer layer is woven from a third yarn and a fourth yarn, the third yarn forming a full-width warp plain weave, and the fourth yarn forming an alternating chain weave and a double-warp chain weave.

[0008] The present invention is further configured such that: the padding number of the third yarn is 1-2 / 1-0 / / full thread, and the padding number of the fourth yarn is 1-0 / 1-0 / 1-0 / 2-0 / 2-0 / 2-0 / / full thread.

[0009] The present invention is further configured such that the first yarn, the second yarn, the third yarn, and the fourth yarn are all made of twisted cotton fiber bundles.

[0010] In summary, this utility model has the following beneficial effects: the longitudinal convex strips and transverse convex ridges abut against each other, hindering the further closing of the outer and inner layers, thereby ensuring the overall structural stability of the insulation cavity. That is, by ensuring the volume of the insulation cavity, the insulation performance of the insulation cavity is guaranteed. At the same time, the insulation cavity between the outer and inner layers is filled with concave and convex structures, which further slows down the air flow in the insulation cavity. The fluffy structure of the cotton fiber bundles themselves can effectively improve the insulation performance of the knitted fabric. Attached Figure Description

Detailed Implementation

[0012] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0013] Example: A warm knitted fabric, such as Figure 1 As shown, the structure includes an outer layer and an inner layer that are stitched together. The outer layer has several longitudinal and transverse ridges on the side near the inner layer. The transverse ridges are arranged in a linear array in the longitudinal direction, and the length of the transverse ridges is equal to the length of the outer layer. The longitudinal ridges are arranged in a linear array in the transverse direction between adjacent transverse ridges, and the length of the longitudinal ridges is equal to the spacing between the transverse ridges. The inner layer has several longitudinal strips arranged in a linear array in the transverse direction on the side near the outer layer. The width of the longitudinal strips is greater than the spacing between the longitudinal ridges. When the outer layer and the inner layer are combined, the longitudinal strips and the transverse ridges fit together. The gaps between adjacent longitudinal ridges on the outer layer and the gaps between adjacent longitudinal strips on the inner layer form a thermal insulation cavity. The longitudinal strips and transverse ridges abut against each other, preventing the outer layer and the inner layer from closing further, thereby ensuring the overall structural stability of the thermal insulation cavity. That is, by ensuring the volume of the thermal insulation cavity, the thermal insulation performance of the thermal insulation cavity is ensured. At the same time, the thermal insulation cavity between the outer layer and the inner layer is filled with concave and convex structures, which further slows down the air flow in the thermal insulation cavity.

[0014] The inner layer is woven from a first yarn and a second yarn. The first yarn forms a full-wear warp plain weave, and the second yarn forms a warp plain weave. The density of the second yarn is less than that of the first yarn. The padding number of the first yarn is 1-2 / 1-0 / / full-wear, and the padding number of the second yarn is 0-1 / 1-2 / / three-wear-one-open. The first yarn forms a smooth surface on the side of the inner layer away from the outer layer with the full-wear warp plain weave. The second yarn forms a warp plain weave with three-wear-one-open, forming a longitudinal raised stripe on the side of the inner layer closer to the outer layer. The outer layer is woven from a third yarn and a fourth yarn. The third yarn forms a full-wear warp plain weave, and the fourth yarn forms alternating chain weave and double-warp chain weave. The padding number of the third yarn is 1-2 / 1-0 / / full-wear, and the padding number of the fourth yarn is 1-0 / 1-0 / 1- 0 / 2-0 / 2-0 / 2-0 / / Full-through: The third yarn forms a flat surface on the outer layer away from the inner layer with a full-through warp plain weave. The fourth yarn forms a chain weave (specifically a closed chain weave in this embodiment). Due to the lack of direct connection between the chain weaves, longitudinal ridges are formed on the outer layer. The fourth yarn also forms a double warp knitted chain weave (specifically a closed double warp knitted chain weave in this embodiment). The double warp loops of adjacent fourth yarns are superimposed on each other in a full-through manner to form transverse ridges. At the same time, because of the presence of double warp loops, the structure of the outer layer is denser than that of the inner layer, thereby ensuring the windproof effect of the outer layer. The first, second, third, and fourth yarns are all made of twisted cotton fiber bundles. The fluffy structure of the cotton fiber bundles themselves can effectively improve the warmth of the knitted fabric.

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.
