Detailed Description

Referring to fig. 1 to 3, an embodiment of the multi-layer fabric 100 of the present invention includes a first woven layer 1, a second woven layer 2, and an inner layer 3.

The first and

second woven layers

1 and 2 are woven with a plurality of warp yarns (not shown) and weft yarns (not shown), respectively. The inner sandwich layer 3 has a plurality of inner layer yarns 31 interlaced and connected between the first woven layer 1 and the second woven layer 2, and the inner layer yarns 31 make the first woven layer 1 and the second woven layer 2 define an accommodation space S in a spaced and opposite manner. The inner layer yarns 31 of the inner interlayer 3 connected between the first flat woven layer 1 and the second flat woven layer 2 define the accommodating space S for storing air at intervals, so that the heat retention property and the buffering property of the fabric are improved on the premise of keeping the firmness. In the present embodiment, the first flat woven layer 1, the second flat woven layer 2, and the inner layer 3 are integrally woven by a shuttle loom (not shown), but in another embodiment, the first flat woven layer 1, the second flat woven layer 2, and the inner layer 3 may be independently woven, and the present invention is not limited thereto. The number of twists of the inner layer yarn 31 is smaller than those of the yarns constituting the first woven layer 1 and the second woven layer 2. Therefore, the inner layer yarns 31 are fluffy to retain air, and the spacing distance between the first flat woven layer 1 and the second flat woven layer 2 is increased to further enlarge the accommodating space S, so that the heat retention property and the buffering property of the accommodating space S are further increased.

In detail, the inner layer yarns 31 include a plurality of first inner layer yarns 311 and a plurality of second inner layer yarns 312 extending obliquely between the first and

second woven layers

1 and 2 along a first direction D1 and side by side in a second direction D2 perpendicular to the first direction D1. Each first inner yarn 311 has a plurality of first inner yarn segments 311a arranged in the first direction D1 and connected between the first and

second woven layers

1 and 2, each second inner yarn 312 has a plurality of second inner yarn segments 312a arranged in the first direction D1 and connected between the first and

second woven layers

1 and 2, the corresponding first and second

inner yarn segments

311a and 312a in the second direction D2 extend alternately with each other. The first inner layer yarns 311 and the second inner layer yarns 312 are arranged to be staggered with each other in the second direction D2. This makes the supporting force provided by the first inner layer yarn 311 and the second inner layer yarn 312 to the first woven layer 1 and the second woven layer 2 more even. However, the arrangement of the inner layer yarns 31 may be changed according to the requirement, and is not limited to this embodiment. In the present embodiment, the warp and weft yarns constituting the first and second

flat woven layers

1 and 2 also extend in the first direction D1 and the second direction D2. Thereby enabling the multi-layer fabric 100 to be more easily integrally woven by the shuttle loom (not shown), but not limited thereto.

In addition, in the present embodiment, the wave troughs refer to portions facing the inner side of the multilayer fabric 100. The junctions C1 of the first woven layer 1 and the inner sandwich layer 3 are arranged at intervals in the first direction D1 and immediately adjacent in the second direction D2, and the first woven layer 1 has a wave-like structure in the first direction D1, and the junctions C1 of the first woven layer 1 and the inner sandwich layer 3 are located at the valley portions of the wave-like structure. The junctions C2 between the second flat layer 2 and the inner layer 3 are arranged at intervals in the first direction D1 and immediately adjacent to each other in the second direction D2, the second flat layer 2 has a wave-like structure in the first direction D1, and the junctions C2 between the second flat layer 2 and the inner layer 3 are located at valley portions of the wave-like structure. Therefore, the accommodating space S between the first flat weaving layer 1 and the second flat weaving layer 2 is further enlarged to accommodate more air so as to increase the heat retention and the buffering performance. However, the positions and the arrangement of the joints C1 and C2 of the first woven layer 1, the second woven layer 2 and the inner layer 3 may be adjusted according to the requirement, and are not limited in this embodiment.

In addition, although in the present embodiment, the two end edges of the first woven layer 1, the second woven layer 2 and the inner layer 3 in the first direction D1 are sewn together, in other embodiments, the two end edges of the first woven layer 1, the second woven layer 2 and the inner layer 3 in the first direction D1 may not be sewn together, and are not limited thereto.

It is worth mentioning, in the utility model inner yarn 31 also can be through in surface finishing coating antibacterial material, change into the yarn of utensil electrostatic adsorption effect or with the yarn blending of utensil electrostatic adsorption effect, so that inner yarn 31 can arrange accommodation space S and form a filter material and use, and can further make clothing or gauze mask in order to provide preliminary epidemic prevention usage.

To sum up, the utility model discloses multilayer fabric 100 passes through the connection of interior intermediate layer 3 in first plain weave layer 1 with between the second plain weave layer 2 inlayer yarn 31 makes first plain weave layer 1 with the second plain weave layer 2 interval relatively defines out jointly and is used for can the air storage accommodation space S to under the prerequisite of having the firmness, increase its warmth retention and buffer.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the description of the present invention are still within the scope of the present invention.
