[0023] Please see Figure 1-4 A roll-type folding pet pee pad includes a pet pee pad roll body 1 and individual pet pee pads 2. The pet pee pad roll body 1 is composed of several individual pet pee pads 2 connected end to end and rolled into a cylindrical shape. A tear line 3 is provided at the connection point of every two individual pet pee pads 2. The tear line 3 is treated with an easy-tear process to ensure that users can easily and neatly tear off the individual pee pads according to their actual needs. A folding line 4 is provided on the individual pet pee pad 2. The position and direction of the folding line 4 are carefully designed to make the individual pee pad more convenient and quick to fold and store, save space, and make it easy to carry and store.
[0024] The single-piece pet pee pad 2 comprises a PE waterproof bottom layer 201, a covering paper 202, a first superabsorbent polymer layer 203, a wood pulp cotton layer 204, a second superabsorbent polymer layer 205, an odor-detergent layer 206, and a non-woven fabric surface layer 207. The PE waterproof bottom layer 201 is made of high-density polyethylene, possessing excellent waterproof performance, effectively preventing urine from seeping onto the ground or other object surfaces, protecting the environment from pollution. The covering paper layer 202 is fixedly connected to the top of the PE waterproof bottom layer 201 using a hot-melt adhesive bonding process. The covering paper layer 202 not only acts as a barrier, preventing direct contact and adhesion between the PE waterproof bottom layer 201 and the upper layer materials, but also provides some protection to the bottom layer material, extending the lifespan of the pee pad.
[0025] A first superabsorbent polymer (SAP) layer 203 is fixedly connected to the top of the paper covering layer 202. The SAP layer 203 is made of highly absorbent resin material, possessing superior absorbency and the ability to quickly absorb large amounts of liquid and lock it inside the resin to prevent backflow. A wood pulp cotton layer 204 is fixedly connected to the top of the SAP layer 203. The wood pulp cotton layer 204 is made of natural wood pulp fiber, is soft in texture, and has good hydrophilicity and breathability. It not only helps absorb urine but also provides a comfortable walking experience for pets.
[0026] A second superabsorbent polymer (SAP) layer 205 is fixedly connected to the top of the wood pulp cotton layer 204. The second SAP layer 205 further enhances the absorbency and water retention of the diaper pad, forming a double absorbency guarantee with the first SAP layer 203, ensuring that urine can be fully absorbed and firmly locked in.
[0027] In practice, a deodorizing layer 206 is fixedly connected to the top of the second superabsorbent polymer layer 205, and a nonwoven fabric surface layer 207 is fixedly connected to the top of the deodorizing layer 206.
[0028] When preparing the deodorizing layer 206, firstly, an activated carbon fiber woven layer 2061 is prepared by weaving activated carbon fibers into shape through a textile process; bamboo charcoal particles are added to the top of the activated carbon fiber woven layer 2061 and fixed through a certain process to form a bamboo charcoal particle adsorption layer 2062; finally, plant essential oil is added to the top of the bamboo charcoal particle adsorption layer 2062 and a suitable slow-release technology is used to form a plant essential oil slow-release layer 2063.
[0029] Specifically, the deodorizing layer 206 includes an activated carbon fiber woven layer 2061, a bamboo charcoal granule adsorption layer 2062, and a plant essential oil slow-release layer 2063. The bamboo charcoal granule adsorption layer 2062 is fixedly connected to the top of the activated carbon fiber woven layer 2061. Bamboo charcoal granules have a well-developed porous structure and strong adsorption capacity, which can further adsorb odors. At the same time, they also have a certain adsorption effect on some impurities and harmful substances in urine. In addition, bamboo charcoal granules also have a certain degree of water absorption, which can help absorb urine.
[0030] In practice, a plant essential oil slow-release layer 2063 is fixedly connected to the top of the bamboo charcoal particle adsorption layer 2062. The plant essential oil slow-release layer 2063 is made of slow-release material that encapsulates natural plant essential oils, which can slowly release plant essential oils. The natural fragrance emitted by the plant essential oils can effectively mask odors, and at the same time, it also has a certain bactericidal and bacteriostatic effect, improving the indoor odor environment.
[0031] The thickness of the bamboo charcoal granule adsorption layer 2062 is less than that of the plant essential oil slow-release layer 2063. The activated carbon fiber woven layer 2061 has a rich porous structure, which can quickly adsorb odor molecules. The bamboo charcoal granule adsorption layer 2062 further enhances the adsorption capacity and also has a certain absorption effect on moisture. The plant essential oil slow-release layer 2063 slowly releases plant essential oils, which can mask odors and emit a natural fragrance, thus improving the indoor odor environment.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
