Description

Technical Field

[0001] The invention relates to the technical field of disposable slippers, in particular to a pair of disposable environmentally friendly slippers and a production method thereof. Background Art

[0002] Disposable slippers are generally used in star-rated hotels, guesthouses, homes, and entertaining guests. Disposable slippers are more convenient to produce; during the production process, disposable slippers have very low requirements for fabrics. There is no need to consider too many factors during production. As long as a suitable size is selected, production can be organized.

[0003] Existing disposable slippers are usually made of S5VS1 wavy sole TS3 cut velvet fabric, and are filled with plastic foam inside. However, the sole of such disposable slippers is thin. When the guest uses it for a long time, the sole will be pressed thinner due to the weight of the guest, affecting the guest's use experience. In addition, the material used is not environmentally friendly. After being discarded, the plastic foam cannot be degraded in a short time, so it will have an impact on the environment. The existing production process of disposable slippers is to process the sole and the upper separately and then sew them. The production process is complicated and not convenient for mass automated assembly line production. Summary of the invention

[0004] The purpose of the present invention is to provide a disposable environmentally friendly slipper and a production method thereof in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0007] The elastic layer comprises a bottom layer of EPE polyethylene foam, the upper surface of which is bonded with a plant-based polyurethane foam, and the upper surface of which is bonded with a top layer of EPE polyethylene foam.

[0008] Furthermore, the upper and lower surfaces of the elastic layer are both provided with hot melt adhesive, so that the elastic layer can be bonded to the top non-woven fabric and the bottom non-woven fabric respectively through the hot melt adhesive.

[0009] Furthermore, the top layer of non-woven fabric includes a top layer base layer, and a suede layer is bonded to the upper surface of the top layer base layer. This arrangement can absorb sweat or water on the soles of customers' feet through the suede surface of the suede layer, prevent the soles of the feet from sticking to the soles due to water, and improve the comfort of the soles of the customers' feet.

[0010] Furthermore, a water-absorbing layer is arranged on the bottom surface of the suede layer, so that the liquid in the suede layer can be absorbed by the water-absorbing layer, thereby preventing excessive moisture in the suede layer from affecting the comfort of the slippers.
