Title: COMPLETELY DEGRADABLE NAPPY
Abstract:
Disclosed is a completely degradable nappy, comprising a surface layer (1), a guide layer (2), an absorption layer (3), a bottom layer (4), leg hole side-seepage prevention partition edges (6), an elastic waistband (7), a front waist sticker (5) and rear waist left and right stickers (8). The surface layer (1), the guide layer (2) and the absorption layer (3) are adhered to a middle position of the bottom layer (4) by means of adhesive. The elastic waistband (7) is provided at two ends of the bottom layer (4). The leg hole side-seepage prevention partition edges (6) are correspondingly provided at two sides of the absorption layer (3). The front waist sticker (5) is provided on the outside of the front end of the bottom layer (4). The rear waist left and right stickers (8) are provided at two side positions at the rear end of the bottom layer (4). The surface layer (1), the guide layer (2) and the bottom layer (4) are made of degradable non-woven fabric with a water-repellent finish. The surface layer (1) forms uniform mesh holes. The absorption layer (3) is formed of toilet paper enveloping degradable water-absorption agent and a fluff-and-pulp mixture. An outer layer of the leg hole side-seepage prevention partition edges (6) is a degradable non-woven fabric with a water-repellent finish, and the inside is a natural latex thread. An outer layer of the elastic waistband (7) is a degradable non-woven fabric, and the inside is a natural latex thread. The main body and the additional materials thereof can all effectively degrade, and have a faster speed of urine penetration, preventing urine from seeping back out.
