Description

Technical Field

[0001] The utility model belongs to the technical field of textiles, and in particular relates to a partially elastic single-sided warp knitted jacquard fabric. Background Art

[0002] With the development of shoes and clothes in modern society, consumers have higher and higher requirements for the functionality, comfort, breathability and feel of shoes and clothes. Fully elastic single-sided fabrics have the disadvantages of easy curling and poor dimensional stability, while partially elastic fabrics are used in clothing and uppers, which are more ergonomic, making the fabrics more fit the human body parts and more comfortable, which makes the demand and requirements for partially elastic fabrics also grow day by day. The structure of existing partially elastic fabrics mostly uses the flying weaving process, the yarn is woven on the flat knitting machine, and the production of the partially elastic structure of the fabric is achieved by changing the yarn, while a disc head in the warp knitting machine can only hold one kind of yarn, and it is impossible to change the yarn during the weaving process, which makes it difficult to achieve the production of partially elastic single-sided warp knitted jacquard fabrics. At present, there are also warp knitted double-layer partially elastic fabrics, which are interwoven by a flat elastic woven layer and a woven layer containing an elastic woven area and an inelastic woven area to form an elastic area and an inelastic area, but because its inelastic area is formed by combining an elastic woven layer and an inelastic woven area, the inelastic area still has a certain elasticity and will produce a certain deformation.

[0025] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0026] The utility model provides a partially elastic single-sided warp knitted jacquard fabric, comprising an elastic area and an inelastic area, wherein the elastic area and the inelastic area both comprise an elastic base layer and an inelastic surface layer connected to each other; the inelastic surface layer of the inelastic area is a warp diagonal structure.

[0027] From the above description, it can be seen that the beneficial effect of the utility model is that the structure of the partially elastic single-sided warp knitted jacquard fabric provided by the utility model can be knitted in one piece using a warp knitting machine, and the production efficiency is high. The non-elastic surface layer of the non-elastic area of ​​the partially elastic single-sided warp knitted jacquard fabric is a warp diagonal structure, and its coil density can lock the structure of the area, reduce the elasticity of the elastic base layer of the non-elastic area, reduce the shrinkage and extensibility of the fabric, so that although the non-elastic area has an elastic base layer, it has no elasticity and will not deform.

[0028] Furthermore, the elastic base layer is woven from elastic fibers of at least 30 deniers or yarns containing elastic fibers, and the inelastic surface layer is woven from inelastic tensile deformation yarns of at least 30 deniers.

[0029] As can be seen from the above description, the use of fibers with a denier of at least 30 to weave the fabric ensures the elasticity and strength of the fabric.

[0030] Furthermore, it comprises a non-elastic area and at least one elastic area; the elastic base layers of the non-elastic area and the elastic area are both plain weave or mesh weave.

[0031] From the above description, it can be seen that the plain weave and mesh weave structures are different, and the elasticity of the elastic base layer formed by the two is different. The mesh weave has better extensibility and air permeability than the plain weave. It can be selected according to different subsequent applications.

[0032] Furthermore, the non-elastic surface layer of the elastic zone is a warp fleece structure, a warp plain structure or a mesh structure.

[0033] From the above description, it can be seen that the warp pile structure, warp plain structure or mesh structure have different structures. When the non-elastic surface layer is combined with the elastic base layer of the plain structure or mesh structure, elastic areas with different elasticities can be formed, which is convenient for selection according to the needs of different degrees of elasticity.

[0034] Furthermore, it comprises a non-elastic area and two elastic areas; the non-elastic surface layer of the elastic area is a warp fleece structure, a warp plain structure or a mesh structure.

[0035] Furthermore, it comprises a non-elastic area and three elastic areas; the non-elastic surface layer of the elastic area is a warp fleece structure, a warp plain structure or a mesh structure.

[0036] It can be seen from the above description that the number, structure and position of the elastic regions can be adjusted according to the required performance of the fabric.
