Description

Technical Field

[0001] The utility model relates to a material for special safety protection gloves, in particular to a polytetrafluoroethylene waterproof and breathable material for special gloves. Background Art

[0002] Special protective articles such as safety protection gloves are widely used in the field of medical and health operations. Since medical staff often need to contact patients and perform medical operations, higher-level protection is required. Medical staff wear special gloves such as antibacterial protective gloves to effectively isolate germs. However, since medical staff need to wear antibacterial protective gloves for a long time, and the existing antibacterial protective gloves have poor air permeability, after long-term use by medical staff, the hands will be soaked in sweat, and the use comfort is poor. Therefore, the existing technology has the problem of poor air permeability. Content of the Utility Model

[0003] The purpose of the utility model is to provide a polytetrafluoroethylene waterproof and breathable material for special gloves. The utility model has the characteristics of good air permeability.

[0004] The technical solution of the utility model: A polytetrafluoroethylene waterproof and breathable material for special gloves includes a base material layer. An outer polytetrafluoroethylene microporous membrane layer is arranged on the outer side of the base material layer. A breathable and wear-resistant coating is arranged on the outer surface of the outer polytetrafluoroethylene microporous membrane layer. An inner polytetrafluoroethylene microporous membrane layer and an inner bottom cloth layer are sequentially arranged on the inner side of the base material layer; the inner bottom cloth layer is woven by warp yarns and weft yarns. The warp yarns are spun from polyester profiled fibers with bean-shaped cross-sections and bamboo charcoal fibers, and the weft yarns are mica ice-cold fibers.

[0005] In the aforementioned polytetrafluoroethylene waterproof and breathable material for special gloves, the pore diameter of the outer polytetrafluoroethylene microporous membrane layer is 0.6 μm.

[0006] In the aforementioned polytetrafluoroethylene waterproof and breathable material for special gloves, the pore diameter of the inner polytetrafluoroethylene microporous membrane layer is 0.25 μm.

[0007] In the aforementioned polytetrafluoroethylene waterproof and breathable material for special gloves, a chlorine dioxide slow-release carrier cloth is arranged between the base material layer and the outer polytetrafluoroethylene microporous membrane layer.

[0008] Compared with the prior art, the utility model is composed of a substrate layer, an outer polytetrafluoroethylene microporous membrane, an inner polytetrafluoroethylene microporous membrane and an inner bottom cloth layer. Through the mutual cooperation between the above structures and strictly controlling the pore diameters of the inner and outer polytetrafluoroethylene microporous membranes, good air permeability can be achieved on the premise of realizing antibacterial properties, thereby effectively improving the comfort of glove wearing. At the same time, the inner bottom cloth layer of the utility model is woven from warp yarns made of polyester profiled fibers with a bean-shaped cross-section and bamboo charcoal fibers blended with weft yarns of mica ice-cold fibers, which not only has good air permeability and antibacterial effect, but also has a cool feeling, improving the use comfort. In summary, the utility model has the characteristic of good air permeability. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The reference signs in the drawings are: 1 substrate layer, 2 - outer polytetrafluoroethylene microporous membrane layer, 3 - breathable and wear-resistant coating, 4 - inner polytetrafluoroethylene microporous membrane layer, 5 - inner bottom cloth layer, 6 - chlorine dioxide slow-release carrier cloth. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0011] The following further illustrates the utility model in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the utility model.

[0012] Embodiment. A polytetrafluoroethylene waterproof and breathable material for special gloves, the composition is as Figure 1 shown, including a substrate layer 1, an outer polytetrafluoroethylene microporous membrane layer 2 is provided on the outer side of the substrate layer 1, a breathable and wear-resistant coating 3 is provided on the outer surface of the outer polytetrafluoroethylene microporous membrane layer 2, and an inner polytetrafluoroethylene microporous membrane layer 4 and an inner bottom cloth layer 5 are successively provided on the inner side of the substrate layer 1; the inner bottom cloth layer 5 is woven by warp and weft, the warp yarns are made of polyester profiled fibers with a bean-shaped cross-section and bamboo charcoal fibers blended, and the weft yarns are mica ice-cold fibers.

[0013] The pore diameter of the outer polytetrafluoroethylene microporous membrane layer 2 is 0.6 μm.

[0014] The pore diameter of the inner polytetrafluoroethylene microporous membrane layer 4 is 0.25 μm.

[0015] A chlorine dioxide slow-release carrier cloth 6 is provided between the substrate layer 1 and the outer polytetrafluoroethylene microporous membrane layer 2.

[0016] Selecting a pore diameter of 0.25 μm for the inner polytetrafluoroethylene microporous membrane layer can well play the role of preventing bacteria and viruses from contacting the hand. While selecting a pore diameter of 0.45 μm for the outer polytetrafluoroethylene microporous membrane layer can block most bacteria and viruses from entering. The two cooperate with each other to effectively block bacteria and viruses from contacting the hand, achieving a good purpose of protecting the user.

[0017] The breathable and wear-resistant coating can be selected as breathable and wear-resistant polyurethane fabric coating glue, and it can be applied on the surface of the outer polytetrafluoroethylene microporous membrane.

[0018] The substrate layer is woven by conventional polyester fibers or nylon fibers in warp and weft.

[0019] The warp of the insole cloth layer is spun from polyester profiled fibers with a bean-shaped cross-section and bamboo charcoal fibers, which not only has good breathability but also can play an antibacterial and deodorizing role; the use of mica cool fibers can have a good sense of coolness and improve the comfort of long-term wearing.

[0020] A chlorine dioxide slow-release carrier cloth is arranged between the substrate layer and the outer polytetrafluoroethylene microporous membrane layer, and chlorine dioxide is released through the chlorine dioxide slow-release carrier cloth to kill the remaining surviving viruses.

[0021] The preparation process of the present utility model: The chlorine dioxide slow-release cloth layer and the outer polytetrafluoroethylene microporous membrane layer are sequentially adhered to the outside of the substrate layer with glue, the inner polytetrafluoroethylene microporous membrane layer and the insole cloth layer are sequentially adhered to the inside of the substrate layer, and then the breathable and wear-resistant coating is applied to the outside of the outer polytetrafluoroethylene microporous membrane to complete the production of the polytetrafluoroethylene waterproof and breathable material for special gloves.
