Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, in particular to a double-sided knitted fabric. Background Art

[0002] Unlike traditional single-sided textiles, double-sided knitted fabrics are made by interweaving two or more layers of knitted yarns. This structure gives the fabric a soft feel and a pleasant touch in multiple directions, providing a better texture and a more comfortable wearing experience. At the same time, since both sides of the fabric are covered with knitted yarns, the use and waste of raw materials can be reduced, and it can be manufactured with fewer processing steps. These advantages make double-sided knitted fabrics a very attractive option, especially in the field of clothing.

[0003] Chinese patent application No. 202120511382.X discloses a double-sided knitted fabric, comprising a knitted surface layer and a knitted bottom layer, in particular, a cotton-covered polyester thread is interspersed back and forth between the knitted surface layer and the knitted bottom layer, and the cotton-covered polyester thread is connected to the knitted surface layer and the knitted bottom layer. This utility model solves the problem of easy pilling of double-sided knitted fabrics, and because the cotton material of the knitted surface layer and the cotton material of the cotton-covered polyester thread can be dyed with the same dye, there is no need to dye them twice separately, so it not only simplifies the dyeing process of the double-sided knitted fabric, but also avoids the problems caused by poor color fastness and floating color caused by polyester dyeing, thereby improving product quality. However, the double-sided knitted fabric does not have the ability to transmit sweat unidirectionally, and its moisture absorption and breathability are poor, so consumers are less comfortable wearing it when sweating.

[0004] Chinese patent application No. 202222489251.3 discloses a comfortable double-sided knitted fabric, including an inner knitted layer, a first sweat-absorbing layer is fixedly sewn on one side of the inner knitted layer, a second sweat-absorbing layer is provided on the side of the first sweat-absorbing layer away from the inner knitted layer, an antibacterial layer is fixedly sewn between the first sweat-absorbing layer and the second sweat-absorbing layer, and an outer knitted layer is fixedly sewn on the side of the second sweat-absorbing layer away from the first sweat-absorbing layer. Both the inner knitted layer and the outer knitted layer are double-sided knitted fabrics, and the inner knitted layer fits the skin to improve the skin-friendly effect and make it comfortable to wear. The wear resistance of the outer knitted layer improves the surface wear resistance of the fabric, improves the surface strength of the fabric, and avoids wear. At the same time, the first sweat-absorbing layer and the second sweat-absorbing layer facilitate sweat absorption and transmission, and the antibacterial layer avoids the growth of bacteria in the sweat-absorbing part, thereby improving comfort. However, the inner knitted layer and the outer knitted layer of the double-sided knitted fabric do not have mesh holes, and the air-liquid permeability is relatively poor when the wearer sweats, which is not conducive to heat discharge. Utility Model Content

[0005] Therefore, in view of the above problems, the utility model provides a double-sided knitted fabric to solve the problems of poor one-way sweat transmission ability, poor moisture absorption and breathability, and poor comfort of the existing double-sided knitted fabric.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A double-sided knitted fabric comprises an upper layer, a middle layer and a lower layer which are stacked in sequence, the upper layer is provided with a plurality of honeycomb meshes, the lower layer is provided with a plurality of transverse meshes, the aperture of the honeycomb meshes is larger than the aperture of the transverse meshes, the honeycomb meshes and the transverse meshes are evenly spaced, and the upper and lower meshes correspond to each other one by one, and the middle layer is a connecting yarn interwoven between the upper layer and the lower layer.

[0008] Furthermore, the upper layer forms a plurality of longitudinal columns arranged along the weft direction and a plurality of transverse columns arranged along the warp direction, and a plurality of hexagonal honeycomb meshes are arranged on both the longitudinal columns and the transverse columns, and the hexagonal honeycomb meshes are formed by empty needle weaving and then closing weaving, and each two adjacent honeycomb meshes on the longitudinal column are connected by a floating line structure, and each two adjacent honeycomb meshes on two adjacent longitudinal columns are connected by a loop structure.

[0009] Furthermore, the lower layer is formed by interweaving warp yarns and weft yarns in a tic-tac-toe pattern, with gaps left at the interlaced knitting locations, and the gaps form transverse mesh holes.

[0010] Furthermore, the connecting yarn forms a tuck structure between the upper layer and the lower layer.

[0011] Furthermore, the yarns for the open needle knitting, closed knitting, floating thread structure and loop structure are all made of hydrophilic yarns.

[0012] Furthermore, the warp yarns and weft yarns are both hydrophobic yarns.

[0013] Furthermore, the connecting yarn is made of hydrophobic yarn.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are:

[0015] 1. A knitted fabric with a three-dimensional structure is provided. The lower layer, i.e., the side in contact with the skin, is made of hydrophobic Tencel; the upper layer, i.e., the side in contact with the air, is made of hydrophilic yarn. The structure has the characteristics of being hydrophobic inside and hydrophilic outside, loose inside and tight outside. According to the principle of wicking effect, a knitted fabric with a unidirectional moisture conduction function is obtained. The lower layer is less humid than the upper layer, forming a humidity gradient effect. The upper and lower layers are connected by hydrophobic yarn, so that moisture can be easily transferred from the inner layer of the fabric to the outer layer of the fabric, accelerating the contact speed between moisture on the surface of the fabric and air, forming a fabric that can keep the body cool and comfortable.

[0016] 2. The connecting yarn connects the upper and lower layers with a tuck structure, which can reduce the tightness of the knitted fabric in contact with the skin in the inner layer, increase the porosity of the middle layer of the fabric, and form a middle layer with a loose structure;

[0017] 3. The upper layer is provided with a plurality of honeycomb meshes, and the lower layer is provided with transverse meshes, and the upper and lower meshes correspond to each other. The pores of the honeycomb meshes provided in the upper layer are larger than the transverse meshes of the lower layer. The difference in mesh size between the upper and lower surfaces and the loose structure of the connecting layer can accelerate the passage of gas and liquid, and the larger pores of the honeycomb meshes provided in the upper layer are conducive to heat discharge.
