Knitted fabric

Abstract

This utility model discloses a knitted fabric, relating to the textile field. The key technical points are: it includes a base layer, which comprises a first yarn. The base layer is longitudinally divided into alternating extended sections and breathable sections. The first yarn forms continuous warp loops on the extended sections, and a sparse weave is formed on the breathable sections. The longitudinal distance of the needle back translation of the sparse weave is greater than the lateral distance of the needle back translation. A double warp-knitted chain structure is formed on the extended sections. The breathable section of this utility model forms a breathable structure through the gaps in the sparse weave formed by the first yarn, avoiding localized yarn density caused by yarn translation. The double warp-knitted chain structure increases the connection strength between adjacent first yarns while also providing good extensibility. The nylon fiber bundles have good tensile strength and elasticity, improving the elasticity of the knitted fabric while ensuring its service life.

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 raw fabric woven through knitting processes (warp knitting or weft knitting) without dyeing or finishing. It is an important raw material for the production of knitted products such as clothing and home textiles. It has unique elasticity and breathability. In order to further enhance breathability, the knitting density difference between local areas is formed by yarn offset on the knitted fabric, which in turn forms some mesh pore structure to improve breathability. However, when stretched, the yarns on both sides of the mesh pore structure are connected to each other with a high contact area, which affects the extensibility of the knitted fabric. 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 a base layer, the base layer including a first yarn, the base layer being divided into alternating extended portions and breathable portions along the longitudinal direction, the first yarn forming continuous warp loops on the extended portion, the first yarn forming a sparse structure on the breathable portion, the longitudinal distance of the needle back translation of the sparse structure of the first yarn being greater than the transverse distance of the needle back translation of the sparse structure of the first yarn.

[0005] The present invention is further configured such that the first yarn forms a warp-knitted chain structure on the extended portion.

[0006] The present invention is further configured such that: the base layer also includes a second yarn, the elasticity of the second yarn being greater than that of the first yarn.

[0007] The present invention is further configured such that: the second yarn forms a missing pad structure, and the longitudinal distance of the needle back translation of the second yarn missing pad structure is greater than the lateral distance of the needle back translation of the second yarn missing pad structure.

[0008] The present invention is further configured such that the second yarn is threaded through and has a gap.

[0009] The present invention is further configured such that: the second yarn is composed of a spandex fiber bundle and a polyester fiber bundle wrapped around the spandex fiber bundle.

[0010] In summary, this utility model has the following beneficial effects: the breathable part forms a breathable structure through the gap of the padding structure formed by the first yarn, avoiding local yarn density caused by yarn translation, while the heavy warp knitting chain structure increases the connection strength between adjacent first yarns and also has good extensibility, and the nylon fiber bundle has good tensile breaking resistance and elasticity, which improves the elasticity of the knitted fabric while ensuring the service life of the knitted fabric. Attached Figure Description

[0012] Figure 2 This is a diagram showing the movement of the second yarn in this invention. Detailed Implementation

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0014] Example: A knitted fabric, such as Figure 1 As shown, it includes a base layer, which includes a first yarn. The base layer is divided into alternating extension sections and breathable sections along the longitudinal direction. The first yarn forms continuous warp loops on the extension section and a sparse structure on the breathable section. The longitudinal distance of the needle back translation of the sparse structure of the first yarn is greater than the lateral distance of the needle back translation of the sparse structure of the first yarn. The first yarn forms a warp knitted chain structure on the extension section.

[0015] Specifically, the first yarn is made of three strands of nylon fiber bundles twisted together. Nylon fiber bundles have good tensile strength and elasticity, which improves the elasticity of the knitted fabric while ensuring its service life. The padding number of the first yarn is 2-0 / 2-0 / 1-1 / 1-3 / 2-0 / / full thread. The missing padding structure does not form loops and directly moves the needle back. Therefore, there is no connection between the yarns, forming gaps. The lateral offset of the missing padding part of the first yarn is small, which further reduces the density of the first yarn in the breathable part. The breathable part forms a breathable structure through the gaps of the missing padding structure formed by the first yarn, avoiding local yarn density caused by yarn translation. The heavy warp knitting chain structure increases the connection strength between adjacent first yarns while also having good extensibility.

[0016] like Figure 1 , Figure 2 As shown, the base layer also includes a second yarn. The elasticity of the second yarn is greater than that of the first yarn. The second yarn forms a sparse structure. The longitudinal distance of the needle back translation of the sparse structure of the second yarn is greater than the transverse distance of the needle back translation of the sparse structure of the second yarn. The second yarn is threaded through and has a gap. The second yarn is composed of spandex fiber bundles and polyester fiber bundles wrapped around the spandex fiber bundles.

[0017] Specifically, the second yarn is formed by three polyester fiber bundles wrapped around a single spandex fiber bundle. The spandex fiber bundle has better elasticity than the nylon fiber bundle. After stretching, the second yarn composed of spandex and polyester fiber bundles provides better elastic recovery performance for the knitted fabric. In this embodiment, the padding number of the second yarn is 1-1 / 1-3 / 2-2 / 2-0 / / one thread and one gap. The large proportion of gap structure shortens the path of the second yarn and accelerates the effect speed of the second yarn during elastic recovery. At the same time, the spaced second yarn reduces the impact of the second yarn on the air permeability of the knitted fabric.

[0018] 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.
