detailed description

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to FIGS. 1 to 3, an undergarment composite shoulder belt includes an elongated shoulder strap body 10 which is adhered to each other by a double-layer fabric, the shoulder strap body 10 having a width in a middle portion along its own length direction. The force receiving portion 11 larger than the both ends is fixed with a silicone sheet 20 inside the double-layered fabric at the force receiving portion 11, and the shoulder belt body 10 is bulged in the thickness direction at a portion where the silica gel sheet 20 is fixed. The silicone sheet 20 has a spindle shape and is provided with a vent hole (not shown) in its own thickness direction.

Referring to FIG. 3, the double-layer fabric includes a bottom fabric 1 and a surface fabric 2 which are sequentially disposed from bottom to top, and a first TPU film 3 which is sequentially covered with a breathable and moisture-permeable layer from bottom to top and between the bottom fabric 1 and the surface fabric 2 , the shaped yarn 4 and the second TPU film 5 which is breathable and moisture permeable. The silicone sheet 20 is located between the second TPU film 5 and the surface layer 2 and is fixed to the second TPU film 5. The silicone sheet 20 and the second cloth 2 are separated from each other to maintain the gas permeability of the silicone portion and to reduce the friction between the human shoulder and the silicone sheet 20 during the movement.

In order to fix the silicone sheet 20, the thickness of the second TPU film 5 is greater than the thickness of the first TPU film 3. In this embodiment, the thickness of the second TPU film is 0.1 to 0.2 mm.

The above-mentioned underwear composite shoulder strap is produced by the following steps:

1 firstly covering a layer of high temperature molded and undeformed underlayer fabric 1 with a breathable and moisture permeable TPU film 3, and then covering the TPU film 3 with a layer of shaped yarn 4 and then performing high temperature fusion to form a first composite body;

2, then the first composite body of the shaped yarn 4 is further covered with a layer of breathable moisture-permeable TPU film 5, for moderate temperature ironing, to obtain a second composite;

3 further on the side of the second composite body on the TPU film 5 contact with the shoulder of the human body and the central position of the force by the mold positioning injection molding method to produce a silica gel sheet 20;

4 Finally, a layer of the surface fabric 2 is entirely covered on the second composite body, and is thermocompression bonded by a hot pressing die, so that the surface layer cloth 2 completely covers the silica gel sheet 20 and the second composite body does not cover the silica gel sheet 20. The parts are completely bonded together to obtain a third composite;

Among them, the surface fabric 1 and the surface fabric 2 may be made of a comfortable fabric suitable for skin contact, such as a warp-knitted or cotton-blend fabric. The silicone sheet 20 is made of a medical grade material and should have good resilience to achieve a reduced pressure and breathability.
