Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, in particular to a high-elasticity air layer fabric. Background Art

[0002] Air layer fabrics usually consist of a three-layer structure, including two surface layers and a relatively fluffy or air-cavity-forming air layer sandwiched between the two surface layers. The still air entrained in the air layer can reduce the heat transfer between the two surface layers, thereby achieving a warming effect. In the prior art, the air layer can be formed by a special textile process or by a multi-layer structure composite. The former has better fabric integrity, while the latter can obtain different types of air layers by adjusting the structure of the middle layer, and the product types are wider.

[0003] The patent document with publication number CN214646368U discloses a highly warm air layer fabric, which includes a base layer, an air layer is arranged above the base layer, a hygroscopic layer is arranged above the air layer, a plurality of first convex points are arranged on the top of the base layer, the plurality of first convex points are distributed in a rectangular array, and the first convex points are bonded to the upper surface of the base layer by glue; a support member is arranged inside the air layer, the cross section of the support member is wavy, the wave crest of the support member is bonded to the hygroscopic layer by glue, and the wave trough of the support member is bonded to the base layer by glue. This technical solution forms a plurality of air cavities between the base layer and the hygroscopic layer by setting a support member with a wavy structure, thereby forming an air layer, but the maintenance of the air layer requires the support member to maintain a wavy structure, and the support member may lose its supporting performance after long-term use, resulting in collapse of the air layer and wrinkles on the fabric. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a high-resilience air layer fabric, which improves the resilience performance, makes it easier for the air layer to maintain its own inner cavity structure, ensures the warmth retention performance of the fabric, and reduces the formation of wrinkles.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A high-elasticity air layer fabric comprises a first base layer, an air layer and a second base layer connected in sequence; a support member is arranged inside the air layer, and the support member comprises a first structural layer and a second structural layer both of which have wavy cross-sections, and an elastic member sandwiched between the first structural layer and the second structural layer; the first structural layer comprises a plurality of protrusions and first wave crests bonded to the first base layer, and a first wave valley formed between adjacent first wave crests, and a first air cavity is formed between the first wave valley and the first base layer; the second structural layer comprises a plurality of protrusions and second wave crests bonded to the second base layer, and a second wave valley formed between adjacent second wave crests, and a second air cavity is formed between the second wave valley and the second base layer; the first wave front and the second wave crest are located in corresponding positions and an interlayer inner cavity is formed between the back sides, and the elastic member is arranged in the interlayer inner cavity; the first wave valley and the second wave valley are located in corresponding positions and are connected to each other.

[0007] The utility model forms an air layer between the first base layer and the second base layer by arranging a support member. The first air cavity and the second air cavity in the air layer can retain stagnant air to reduce the heat transfer rate between the first base layer and the second base layer, and an elastic member is arranged inside the support member. When the fabric is stretched by an external force, the elastic member is squeezed by the first wave peak and the second wave peak and stores energy. After the external force is removed, the elastic member rebounds and restores the first wave peak and the second wave peak, thereby maintaining the air cavity structure in the air layer and avoiding the collapse of the first wave peak and the second wave peak to cause wrinkles in the fabric. In addition, the support member in the utility model has a symmetrical structure, and the stress applied by the support member to both sides of the fabric is basically equal, thereby avoiding wrinkles of the fabric due to unbalanced stress on both sides.

[0008] Furthermore, the cross-section of the elastic member is circular or annular.

[0009] Furthermore, the elastic member includes a core body with a circular cross section and a covering body with a circular cross section arranged on the outer periphery of the core body.

[0010] Furthermore, the core body is made of elastic rubber material, and the covering body is made of memory foam material.

[0011] Furthermore, the elastic member is glued to the back sides of the first wave crest and the second wave crest.

[0012] Furthermore, transition air cavities are formed between two sides of the elastic member and the first wave valley and the second wave valley.

[0013] Furthermore, the first wave valley and the second wave valley at corresponding positions are fixedly connected by a connecting yarn.

[0014] Furthermore, a skin-friendly layer is connected to the outer side of the first base layer, and a wear-resistant layer is connected to the outer side of the second base layer.

[0015] Furthermore, the skin-friendly layer is weft-knitted with skin-friendly yarns into rib structures and tuck structures at alternating intervals, and the wear-resistant layer is weft-knitted with wear-resistant yarns into rib structures and tuck structures at alternating intervals.

[0016] Furthermore, the skin-friendly yarn is composed of elastic fibers and skin-friendly fibers wrapped around the elastic fibers; and the wear-resistant yarn is composed of elastic fibers and wear-resistant fibers wrapped around the elastic fibers.

[0017] The application of the utility model can achieve the following beneficial effects:

[0018] 1. The utility model is provided with an air layer, and the air layer forms an air cavity through the support member. The air cavity can retain stagnant air to reduce the heat transfer rate between the first base layer and the second base layer, thereby improving the thermal insulation performance of the fabric.

[0019] 2. The utility model provides an elastic member inside the supporting member, which can be compressed to store energy when the fabric is stretched and then rebound to restore the first wave crest and the second wave crest, thereby maintaining the air cavity structure in the air layer.

[0020] 3. The support member in the utility model has a symmetrical structure, and the stress applied by the support member to both sides of the fabric is basically equal, thereby preventing the fabric from wrinkling due to unbalanced stress on both sides.

[0021] 4. In some embodiments of the present invention, the elastic member is composed of a core body made of rubber material and a covering body made of memory foam material, so that the elastic member has better resilience and improves the touch. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0026] Reference Figure 1 and Figure 2 The utility model provides a high resilience air layer fabric, which comprises a first base layer 1 and a second base layer 2 in a planar structure and an air layer 3 sandwiched between the first base layer and the second base layer, a skin-friendly layer 4 close to the human skin when in use is glued to the outside of the first base layer, and a wear-resistant layer 5 away from the human skin when in use is glued to the outside of the second base layer;

[0027] A support member is provided in the air layer, and the support member is composed of a first structural layer 31 and a second structural layer 32 both of which have wavy cross-sections, and an elastic member 33 sandwiched between the first structural layer and the second structural layer; the first structural layer 31 includes a plurality of protrusions and first wave crests 311 glued to the first base layer 1, and a first wave valley 312 formed between adjacent first wave crests 311, and a first air cavity 313 is formed between the first wave valley 312 and the first base layer; the second structural layer 32 includes a plurality of protrusions and second wave crests 321 glued to the second base layer, and a second wave valley 322 formed between adjacent second wave crests, and a second air cavity 323 is formed between the second wave valley and the second base layer. When in use, relatively stagnant air is contained in the first air cavity and the second air cavity. The low thermal conductivity of air can reduce the thermal conductivity between the first base layer and the second base layer, thereby achieving a warming effect; the elastic member is composed of a core body 331 with a circular cross-section and a sheathing body 332 with a circular cross-section arranged on the outer periphery of the core body. The core 331 is made of elastic rubber material, which is used to improve the basic structural strength of the elastic member. When the fabric is bent, the core can store energy and then provide a rebound force to make the fabric tend to be flat. The covering body 332 is made of memory foam material, which is used to improve the touch of the fabric. When the fabric is stretched, the covering body is squeezed by the first wave crest and the second wave crest to store energy and then provide a rebound force to reset the first wave crest and the second wave crest. In this embodiment, the support member is a symmetrical structure, and the stresses on the first base layer and the second base layer connected to the support member are basically the same, which can prevent the fabric from wrinkling; the elastic member is glued to the back side of the first wave crest and the second wave crest, and a transition air cavity 34 is formed between the two sides of the elastic member and the first wave valley 312 and the second wave valley 322. The transition air cavity is between the first air cavity and the second air cavity at the corresponding position, and can play a buffering role when the first air cavity and the second air cavity exchange gas, further reducing the heat transfer rate on both sides of the fabric and improving the thermal insulation effect. The first wave valley and the second wave valley at the corresponding position are in contact with each other and are fixedly connected by the connecting yarn 35;

[0028] The skin-friendly layer is made of skin-friendly yarns weft-knitted into rib structures and tuck structures with alternating intervals, and the skin-friendly yarns are composed of elastic fibers and skin-friendly fibers wrapped around the elastic fibers; the skin-friendly fibers are natural fibers such as wool fibers and cotton fibers, or synthetic fibers with good skin-friendliness such as Viscose fibers and Lyocell fibers;

[0029] The wear-resistant yarns of the wear-resistant layer are weft-knitted into rib structures and tuck structures with alternating intervals, and the wear-resistant yarns are composed of elastic fibers and wear-resistant fibers wound around the elastic fibers.

[0030] In some other embodiments, Figure 1On the basis of the first structural layer and the second structural layer, other functional layers are additionally provided. For example, a hydrophobic layer can be formed on the outer side of the wear-resistant layer using a hydrophobic treatment liquid. The hydrophobic layer can use its own hydrophobic ability to prevent water carrying stains from penetrating into the fabric. For another example, short pile can be attached to the inner sides of the first structural layer and the second structural layer to form a fluff layer. The fluff layer can use its own fluffy characteristics to further form a stagnant secondary air layer, thereby improving the warmth retention effect.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
