Bathroom floor mats are a product that can effectively scrape moisture at the entrance and exit of the bathroom to keep the indoor floor dry. There are many kinds of materials used to make floor mats on the market. Generally speaking, they can be divided into soft floor mats and hard floor mats. Soft floor mats are more comfortable to step on than hard floor mats. However, the common materials used to make soft floor mats on the market do not have antibacterial and mildew-proof functions. They are easy to breed bacteria after absorbing moisture and are easy to mold in a humid state for a long time. They do not meet the health and safety requirements of consumers. Therefore, it is necessary to develop an antibacterial and mildew-proof recycled soft cotton to be suitable for making soft floor mats to meet consumer needs. Utility Model Content

[0013] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0014] Embodiment 1
[0015] Combination Figure 1 The present embodiment is described in detail. An antibacterial and mildew-proof recycled soft cotton comprises: a recycled soft cotton main body; the recycled soft cotton main body comprises a soft layer 1, a water-absorbing layer 2, an antibacterial and mildew-proof layer 3 and a reinforcing layer 4 which are compounded in sequence; the soft layer 1, the water-absorbing layer 2, the antibacterial and mildew-proof layer 3 and the reinforcing layer 4 are compounded by needle punching; the soft layer 1 is a fine-denier recycled full-dull polyester fiber layer; the reinforcing layer 4 is a coconut shell fiber layer.
[0016] Specifically, the reinforcing layer 4 is laid in a cross-laying manner, which can improve the tensile strength of the reinforcing layer 4. Coconut shell fiber is a natural cellulose fiber obtained by soaking, beating, loosening, removing impurities, and drying the discarded coconut shell after the pulp and coconut juice are taken away. Coconut shell fiber is moisture-resistant, has a higher elongation at break than flax, bamboo, and cotton fibers, and has the ability to maintain a complete shape and restore to an initial state. This advantageous feature can be used to process coconut shell fiber by needle punching as a reinforcing layer of the regenerated soft cotton body.
[0017] Furthermore, the fineness of the fine-denier regenerated full-dull polyester fiber is 1.67dtex. Specifically, the fine-denier regenerated full-dull polyester fiber is made of regenerated polyester full-dull slices as raw materials and prepared by a melt spinning process. Fine-denier fiber is thinner than traditional fibers, so it feels more fluffy and softer than ordinary fibers. Natural fibers are easy to wrinkle and artificial fibers are not breathable. Fine-denier fiber can overcome these shortcomings well. The fine-denier regenerated full-dull polyester fiber layer serves as a soft layer, and the surface is a uniform, compact, soft and highly elastic fine velvet, so it is not easy to cause the problem of cilia shedding, and the fiber has a large specific surface area and wicking effect, and has extremely strong water absorption and moisture conduction functions; at the same time, due to the high strength and toughness of the fine-denier fiber, it has a longer service life, and the high-molecular polymer fiber will not produce protein hydrolysis like cotton fiber, and is not easy to mold and rot, and the service life is significantly increased.
[0018] Furthermore, the water-absorbing layer 2 is a U-shaped cross-section polyester fiber layer. The U-shaped cross-section polyester fiber is a fiber produced by a U-shaped spinneret, which is a differentiated fiber. The fiber has a certain twist in the longitudinal direction, making it fluffy and soft. The fiber cross-section is shaped like the English letter U, and has deep grooves in the longitudinal direction. These grooves can store a certain amount of water, and the fiber has a large specific surface area and a good wicking effect. The water-absorbing layer 2 is not only soft and fluffy, but also can absorb and store the water guided by the soft layer 1, so as to achieve the effect of water absorption. Its water absorption performance can achieve the water absorption effect required by the bathroom mat.
[0019] Furthermore, the antibacterial and mildew-proof layer 3 is an antibacterial, anti-mite and anti-mildew modified viscose fiber layer. Specifically, the antibacterial, anti-mite and anti-mildew modified viscose fiber is prepared by blending and spinning the plant Chinese medicine Litsea cubeba, fennel extract aqueous solution and thyme essential oil microcapsules with viscose spinning solution. Litsea cubeba has high yield and abundant resources. Its main component citral accounts for more than 80%, which has good antifungal and good antibacterial effects; the main components of fennel extract are anisole, anisone, anisaldehyde, etc., which have good mite repellency and good antibacterial properties; the main component of thyme essential oil is thymol, which has strong antifungal, antibacterial and good mite repellent effects; the active ingredients in plant extracts are mostly secondary metabolites of plants, which can effectively kill pathogenic microorganisms or inhibit their growth. Compared with common viscose fiber, the antibacterial, anti-mite and anti-mildew modified viscose fiber has no change in its crystal cell structure, no significant change in the cross section, and obvious grooves on the longitudinal surface; the antibacterial rates against Staphylococcus aureus, Escherichia coli, and Candida albicans are 95.50%, 99.12%, and 79.35%, respectively; the repellency rate against mites is greater than 60%, and it has a strong anti-mite function; the anti-mildew grade is 0, and the anti-mildew effect and water washability are excellent.
[0020] Embodiment 2
[0021] Combination Figure 2 This embodiment is described in detail. The difference from the first embodiment is that a polyurethane elastomer 5 is further provided on the side of the reinforcing layer 4 away from the antibacterial and mildew-proof layer 3. The polyurethane elastomer 5 is compounded with the reinforcing layer 4 by a mesh hot melt adhesive. The thickness of the polyurethane elastomer 5 is 3-5 mm. The polyurethane elastomer 5 is an elastic material between general rubber and plastic. It has both the high elasticity of rubber and the high strength of plastic, and has excellent oil resistance, impact resistance, radiation resistance, load-bearing heat insulation, insulation and other properties. The polyurethane elastomer is provided to improve the elasticity of the recycled soft cotton body.
[0022] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
