preparation example Construction

[0023] Please refer to Figure 1-2 Shown, a kind of preparation method of elastic ear cloth of the present invention comprises the following steps;

[0024] Step 1. Stretch the non-woven fabric 102 along its length and set it aside;

[0025] Step 2. Stretch the TPU film 101 along its length, and set it aside;

[0026] Step 3. Compound the stretched non-woven fabric 102 obtained in step 1 with hot melt adhesive on the upper and lower sides of the stretched TPU film 101 obtained in step 2 to obtain the elastic ear cloth 10 .

[0027] It can be seen from the above description that the beneficial effect of the present invention lies in: the method provided by the present invention has a simple preparation method and low cost, and the TPU film that does not have stretchability and the non-woven fabric that has been stretched to a certain extent are bonded to obtain elasticity. Earcloth, non-woven fabric is attached to both sides of the TPU film, so that the resulting earband is e...

Embodiment 1

[0045] A preparation method of elastic ear cloth, specifically comprising the following steps;

[0046] Step 1. Stretch 15g of spunbonded non-woven fabric with a width of 400mm along its length direction until the width is 280mm, and set aside;

[0047] Step 2. Stretch 25g of TPU film 101 with a width of 290mm along its length direction until the width is 280mm, and set aside;

[0048] Step 3. Compositing the stretched spunbond nonwoven fabric obtained in step 1 on both sides of the stretched TPU film 101 obtained in step 2 through 6815 rubber glue to obtain elastic ear cloth 10;

[0049] Wherein, the width ratio of the spunbonded nonwoven fabric before and after stretching is 10:7-7.25, and the width ratio of the width of the TPU film 101 before and after stretching is 2.9:2.8;

[0050] Gained elastic ear cloth 10 is used for preparing the ear band of mouth mask.

Abstract

The invention discloses a method for preparing elastic ear cloth, which belongs to the technical field of face masks. The preparation method combines a TPU film that does not have stretchability with a non-woven fabric that has been stretched to a certain extent to obtain elastic ear cloth. After the earband is formed, it will not cause pressure on the ear, which avoids ear pain caused by long-term wearing. The present invention also provides a preparation device for elastic earcloths, comprising a frame and a first non-woven fabric pulling mechanism, a second non-woven fabric pulling mechanism, an elastic film pulling mechanism, a first glue spraying mechanism, and a frame arranged on the frame. machine, the second glue spraying machine, the first pair of pressure rollers, the second pair of pressure rollers, and the hot press; it can effectively stretch the TPU film and non-woven fabric to different degrees, the preparation process is smooth, and the preparation device structure is simple and easy to promote The earband made of the prepared elastic ear cloth is not easy to cause ear pain even if it is worn for a long time, and the degree of automation is high.

Description

technical field [0001] The invention belongs to the technical field of masks, and in particular relates to a preparation method and a preparation device of elastic ear cloths. Background technique [0002] The mask is composed of the face and ear straps. When in use, the ear straps are hooked to the ears so that the mask can be worn on the face to cover the mouth and nose, which can effectively prevent viruses, bacteria, and inhalable particles from entering the respiratory tract. Effective physical protection. The ear loops of masks are mostly round or oblate elastic cords, similar to elastic bands. The specifications are usually 2.5mm, 3mm, 4mm, and 5mm in diameter, with strong resilience. But when encountering special circumstances such as pollen season and epidemic infectious diseases, due to frequent going out, population flow and density, people need to wear masks for a long time, and often need to wear them continuously for more than 6 hours. The earband made of thi...
