[0002] Disposable slippers, as common sanitary products in the modern hotel industry, not only provide convenience for guests, but also reflect the hotel's emphasis on hygiene and comfort. The original intention of this kind of slipper design is to allow guests to enjoy a clean and comfortable wearing experience during their stay.

[0003] Existing disposable slippers, such as the one with the publication number CN201806002U named disposable slipper, include a shoe strap and a sole. The sole is composed of a plant stem layer and a non-woven fabric layer connected together. The plant stem layer is composed of several reed rods spliced horizontally with each other.

[0004] However, in addition to the above two materials for composite processing, existing disposable slippers often use materials such as EVA, PVC, TPR, and dot plastic fabrics for composite. It is not only not easy to process, but also different materials need to be separated first during recycling, and the process is rather cumbersome. Therefore, we provide an airbag type slipper.

[0043] Embodiment 5

[0044] Please refer to Figure 1, An airbag slipper, comprising a sole 1, an airbag layer 4 for improving the cushioning performance of the sole 1 is arranged inside the sole 1.

[0055] A method for producing airbag slippers comprises the following steps:

[0056] Step 1: Making the sole, using a screw extruder to prepare PP melt, the filtration pressure is set in the range of 8MPa, the temperature range is controlled in the range of 200℃, the screw speed is in the range of 60rpm, the PP melt is filtered by the filter and pumped into the die head by a metering pump, the metering speed is in the range of 20rpm, and a PP film with thickness and width is made by a casting and laminating equipment. After the PP film is made, it is further made into a single-layer airbag layer by a laminating process, and the single-layer airbag layer is hot-melt welded to the upper layer 3 by ultrasonic hot melting. After welding, it is cut into a sole shape to obtain a sole with an airbag;

[0057] Step 2: Make the upper and the shoe upper. Both the upper and the shoe upper are made of PP non-woven fabrics using a spunbond process. After being made, they are cut into corresponding specifications and shapes according to the shoe size;

[0058] Step 3: Fix the sole, upper and upper by ultrasonic hot-melt welding to complete the production of disposable slippers.

[0059] Further, the coating process is specifically as follows:

[0060] Step 1: Send the prepared PP film to the laminating equipment. The laminating equipment has a roller with a bowl groove, and cooperates with a vacuum pump to adsorb the PP film, so that an air cavity is formed on the PP film to complete the production of the surface film;

[0061] Step 2: another piece of PP film is flattened by a smooth roller to form a base film;

[0062] Step 3: Relying on the heat of the surface film and the base film themselves, the two are rolled and laminated to form a single-layer airbag layer.

[0063] A single-layer airbag layer 4 and an upper layer 3 are used. The upper upper layer 3 has a flat surface and is used to contact the foot. The lower airbag layer 4 is used to provide a cushioning effect. The airbag layer 4 is located at the bottom and can be used as the bottom of the sole 1 to reduce costs.

[0064] Example 8

[0065] See also Figure 1 and Figure 6, An airbag-type slipper, comprising a sole 1, an airbag layer 4 for improving the buffering performance of the sole 1 is arranged inside the sole 1, the airbag layer 4 is formed by laminating a surface film with grooves and a bottom film, a plurality of three-dimensional air cavities 6 are arranged on the surface of the airbag layer 4, and the air cavities 6 are evenly distributed on the airbag layer 4 in a staggered arrangement. Above the sole 1, there is an upper 2 for wrapping the front part of the foot. Both the sole 1 and the upper 2 are made of PP material and are connected by hot melt welding to each other.

[0066] Furthermore, the airbag layer 4 inside the sole 1 is a double-layer composite airbag layer 4 with a total thickness of 10 mm, and it is thickened by an overall lamination method or a local composite lamination method for the heel and the sole.

[0067] A production method of an airbag-type slipper, comprising the following steps:

[0068] Step 1: Manufacture the sole. Rely on a screw extruder to prepare PP melt, with its filtration pressure set in the range of 6 MPa, the temperature range controlled in the range of 180 °C, the screw speed in the range of 40 rpm. After the PP melt is filtered by a filter, it is pumped into a die head by a metering pump, and the metering speed is in the range of 15 rpm. Through a casting and coating device, a PP film with thickness and width is made. After the PP film is made, it is further made into a single-layer airbag layer through a coating process, and two single-layer airbag layers are laminated and compounded by ultrasonic hot melt to form a laminated structure with multiple composites. The multi-layer film after compounding is cut into the shape of the sole to obtain a sole with airbags.

[0069] Step 2: Manufacture the upper and the upper part of the shoe. Both the upper and the upper part of the shoe are made of PP non-woven fabric by a spunbond process, and after being made, they are cut into corresponding specifications and shapes according to the shoe size.

[0070] Step 3: Fix the sole, the upper and the upper part of the shoe by ultrasonic hot melt welding to complete the production of disposable slippers.

[0071] Furthermore, the specific coating process is as follows:

[0072] Step 1: Feed the made PP film into the coating device. The coating device has a roller body with bowl-shaped grooves, and cooperates with a vacuum pump to adsorb the PP film, so that air cavities are formed on the PP film to complete the production of the surface film.

[0073] Step 2: Level another PP film through a smoothing roller body to make a bottom film.

[0074] Step 3: Roll and laminate the two by relying on the self-heat of the surface film and the bottom film to make a single-layer airbag layer.

[0075] The sole 1 can be compounded with multiple airbag layers 4 in an up-and-down arrangement to increase the thickness of the bottom, improve comfort, and have a heightening effect. By locally thickening, the local height can be increased. Compared with the overall thickening method, it can reduce costs and can focus on buffering the heel and sole parts to improve the comfort at this position.
