An antibacterial layer is made by adding an antibacterial material to the base fiber fabric on the inner layer, and wrapping layers such as polyester fiber materials are provided on both sides of the antibacterial layer to form an antibacterial fabric product. However, the current method of adding antibacterial materials to fiber fabrics is carried out by steam spraying or immersion co-bathing, which requires high processing equipment and a long processing time, thus affecting the processing efficiency.

Detailed implementation manners

[0025] The present application provides a waterproof, breathable and antibacterial fabric. The main body of the waterproof, breathable and antibacterial fabric is an antibacterial layer, and waterproof layers are arranged on both sides of the antibacterial layer. In order to achieve the purpose of manufacturing an antibacterial fabric with waterproof performance, the present application also provides a tensioning device capable of locally pressing the antibacterial layer;

[0026] The antibacterial layer is prepared by dropping a liquid antibacterial material on the surface of a fiber fabric, and then through jet steam treatment, shaping and cutting treatment;

[0027] Among them, the antibacterial material can be diffused on the fiber fabric by means of jet steam.

[0028] During the processing of the antibacterial layer, a tensioning device is used to locally press the fiber fabric, so that the local position of the fiber fabric can be kneaded and pressed to adjust the tightness of the antibacterial layer;

[0029] The liquid antibacterial material in the present application uses a nano silver ion solution.

[0030] The following describes specific embodiments of the present invention.

[0031] Refer to Figures 1-5 as shown, and describe an embodiment of the preparation process of the antibacterial layer in the waterproof, breathable and antibacterial fabric provided by the present invention:

[0032] First, feed the fiber fabric into the tensioning device from one side, and then use the feeding rollers 13 and the rotating rollers 23 on both sides to cooperate to locally press the fiber fabric, and spray the antibacterial material on the upper side of the pressed fiber fabric;

[0033] Then, stretch the fabric, and spray steam from the lower side of the fabric to wet the fabric, so that the antibacterial material spreads on the fabric;

[0034] Finally, export the antibacterial material from the other side of the tensioning device, perform shaping and cutting treatment, and finally set waterproof layers on both sides thereof, and connect the antibacterial layer and the two waterproof layers together by knitting.

[0035] The antibacterial layer and the waterproof layer are set to be thinner, so as to maintain the air permeability of the breathable antibacterial fabric.

[0036] Refer to Figures 3-5 as shown, and describe an embodiment of the tensioning device used in the preparation process of the antibacterial layer in the waterproof, breathable and antibacterial fabric provided by the present invention, and locally press the fiber fabric in the fabric placement state I1 state:

[0037] A rotation driver 12 for driving the feeding roller 13 to rotate is installed on the extension platform 11. The output shaft of the rotation driver 12 is connected to the feeding roller 13, and each feeding roller 13 is controlled by a rotation driver 12 respectively.

[0038] In this application, the rotation driver 12 can be a stepper motor or a servo motor. By starting the rotation of the rotation driver 12, the feeding roller 13 is driven to rotate, and the fiber fabric is conveyed and processed.

[0039] A fixing ring 22 is connected to the inner side of the pressing arm 21 through a torsion spring I. The two ends of the torsion spring I are respectively welded and fixedly connected to the pressing arm 21 and the fixing ring 22, and the fixing ring 22 is installed on the extension platform 11 through fasteners.

[0040] Under the action of the torsion spring I, the pressing arm 21 drives the roller 23 to automatically press towards the feeding roller 13, so that the two rollers 23 on both sides can cooperate with the two feeding rollers 13, so as to perform local pressing treatment on the fiber fabric in the fabric placement state I 1 without controlling the rotation of the feeding roller 13.

[0041] A jacking device is vertically movably installed in the middle of the extension platform 11. The jacking device rises from the lower side of the fiber fabric to perform local kneading and pressing treatment on the fiber fabric, thereby controlling the tightness of the antibacterial layer.

[0042] Refer to Figures 2-3 As shown, an example of the tensioning device used in the preparation process of the antibacterial layer in the waterproof, breathable and antibacterial fabric provided by the present invention is described. A liquid antibacterial material is dropped on the fiber fabric, and steam is sprayed to the lower side of the fiber fabric:

[0043] A spraying frame 14 is installed on the extension platform 11 through fasteners.

[0044] The liquid antibacterial material is dropped on the fiber fabric through the drip tube, and steam is sprayed to the lower side of the fiber fabric through the steam spray pipe to wet the fabric, so that the antibacterial material spreads on the fabric.

[0045] Refer to Figure 2 and Figures 6-8 As shown, an example of the tensioning device used in the preparation process of the antibacterial layer in the waterproof, breathable and antibacterial fabric provided by the present invention is described.

The lower side of the fixing plate 34 is vertically slidably connected to the lifting seat 31 . The stretching disk 45 is mounted on the lifting seat 31 .

[0047] A first telescopic driver for driving the lifting seat 31 to slide vertically is installed on the fixed plate 34, and the movable end of the first telescopic driver is fixedly connected to the lifting seat 31 by a fastener; the telescopic driver in the present application can be an electric telescopic rod or a hydraulic cylinder.

[0048] The end of the lifting seat 31 is rotatably connected to a rotating unfolding arm 32 , and the rotating unfolding arm 32 is rotatably connected to a pressing roller 33 . The rotating unfolding arm 32 is controlled to rotate so that the pressing roller 33 is pressed toward the rotating roller 23 .

[0049] The lifting seat 31 is controlled to rise from the middle of the partially clamped fabric, and the rotating unfolding arm 32 is rotated toward the roller 23. After the fabric is stretched, the pressing roller 33 can cooperate with the feeding roller 13 and the roller 23 to press the fiber fabric in the fabric placement state Ⅱ2.

[0050] In this state, the fiber fabric is locally kneaded by the stretching disk 45 to adjust the tightness of the antibacterial layer to be consistent with the waterproof layer, thereby improving the use effect of the waterproof, breathable and antibacterial fabric.
