Under the structure that the plain woven layer is tightly woven, when the braid is subjected to transverse pulling force in the use process, the deformation distance during pulling is prevented from being limited through the tightly woven plain woven layer, and the situation that the braid is too long in deformation, so that the waterproof effect is weakened after the waterproof plastic film is deformed or torn is avoided; when the braid is subjected to torsion pulling force, the waterproof plastic film is twisted and torn, the interior of the braid loses the waterproof effect, and compared with a traditional braid, the braid prolongs the service life of the waterproof plastic film in the braid.

Description

Technical Field

[0001] The utility model relates to the technical field of webbings, in particular to a waterproof webbing. Background Art

[0002] Waterproof webbing generally refers to bandages or tapes that remain adhered and waterproof in wet or underwater environments.

[0003] Therefore, in actual use, it is necessary to consider the waterproofness of the webbing when operating in a humid environment or underwater environment. Therefore, the webbing needs to be specially treated, such as increasing the waterproofness of the webbing or the anti-corrosion effect through waterproof materials, and coating the surface of the webbing with a waterproof layer to further improve the overall waterproofness of the webbing.

[0004] However, most existing webbings are made of nylon. Due to its high wear resistance, high strength and lightweight properties, nylon is widely used in actual use. However, when working underwater for a long time, the waterproofness of the webbing will weaken over time. Therefore, it is necessary to further improve the waterproof effect of the webbing by applying a waterproof coating on the surface of the nylon material. However, in actual use, due to the different use environments of the webbing, the wear and tear on the webbing surface is also different. Therefore, simply applying a waterproof coating still cannot achieve an effective waterproof effect.

[0005] Therefore, the utility model proposes a waterproof webbing. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a waterproof webbing.

[0007] In order to achieve the above object, the utility model adopts the following technical solution: a waterproof webbing, comprising a webbing body, the webbing body comprising a plain weave layer and a twill dense layer, the plain weave layer being arranged on the upper and lower sides of the twill dense layer, and a waterproof plastic film being arranged between the plain weave layer and the twill dense layer;

[0008] The plain weave layer is formed by weaving polyester fibers and nylon fibers in warp and weft, the polyester fibers on the plain weave layer are warp yarns, and the nylon fibers on the plain weave layer are weft yarns; the twill encryption layer is formed by weaving polyester fibers and nylon fibers in warp and weft, the nylon fibers on the twill encryption layer are warp yarns, and the nylon fibers on the twill encryption layer are weft yarns.

[0009] As a preferred embodiment, the plain woven layer, the waterproof plastic film and the twill dense layer are formed by laminating through a flat-plate vulcanizing machine.

[0010] The beneficial effect of adopting the above-mentioned further scheme is: the plain woven layer, the waterproof plastic film and the twill dense layer are pressed together by a flat vulcanizing machine, so that the plain woven layer, the waterproof plastic film and the waterproof plastic film are tightly fitted together to form an integrated structure. The advantage of this structure is that the distance between the plain woven layer, the waterproof plastic film and the twill dense layer is reduced to avoid liquid penetration.

[0011] As a preferred embodiment, both ends of the plain woven layer, waterproof plastic film and twill dense layer are provided with waterproof plywood, and the waterproof plywood completely covers and wraps both ends of the plain woven layer, waterproof plastic film and twill dense layer.

[0012] The beneficial effect of adopting the above-mentioned further scheme is: the two ends of the plain woven layer, the waterproof plastic film and the twill dense layer are clamped and fixed by the waterproof plywood, so as to prevent liquid from entering from the two ends of the ribbon body during use, causing the plain woven layer, the waterproof plastic film and the twill dense layer to expand after absorbing water, resulting in gaps between the plain woven layer, the waterproof plastic film and the twill dense layer.

[0013] As a preferred embodiment, a nano waterproof coating is provided on the outer side of the plain woven layer, and the nano waterproof coating is covered on the plain woven layer by coating and curing.

[0014] The beneficial effect of adopting the above further scheme is: the plain woven layer is waterproofed by the nano waterproof coating. Since the nano waterproof coating can form a tiny nano-level coating, it effectively prevents water molecules from penetrating into the interior of the ribbon, and the nano waterproof coating keeps the ribbon waterproof while ensuring its breathability.

[0015] As a preferred embodiment, a silicone coating is provided on the outer side of the nano waterproof coating, and the silicone coating is covered on the nano waterproof coating by coating and curing.

[0016] The beneficial effect of adopting the above-mentioned further scheme is: the nano-waterproof coating is protected by the silicone coating to prevent the nano-waterproof coating from being worn during use, resulting in a weakening of the waterproof effect. Since the silicone material itself has good chemical resistance, it can resist the erosion of many chemicals, and the silicone coating has excellent high temperature resistance and can usually withstand temperatures of up to several hundred degrees Celsius. This allows the webbing coated with the silicone coating to maintain stable performance in a high temperature environment and is not easily deformed or damaged.

[0017] As a preferred embodiment, the nano waterproof coating completely covers the plain woven layer, the waterproof plastic film and the twill dense layer, and the silicone coating completely covers the nano waterproof coating.

[0018] The beneficial effect of adopting the above-mentioned further scheme is: the nano waterproof coating is completely covered on the plain woven layer, the waterproof plastic film and the twill dense layer, thereby reducing the waterproof dead angle, improving the waterproof effect, and preventing liquid from entering the interior of the plain woven layer, the waterproof plastic film and the twill dense layer through the side. Further, under the action of the silicone coating, it is completely covered on the nano waterproof coating, providing more effective protection for the nano waterproof coating.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are:

[0020] In the present invention, the tightly woven plain weave layer prevents the webbing from being subjected to lateral pulling force during use by limiting the deformation distance during pulling through the tightly woven plain weave layer, thereby preventing the webbing from being deformed too long, which would cause the waterproof plastic film to be deformed or torn, thereby weakening the waterproof effect. Furthermore, through the design of the twill encryption layer, the waterproof plastic film is twisted and torn when the webbing is subjected to torsional pulling force, resulting in the loss of waterproof effect inside the webbing. Compared with traditional webbing, the present webbing improves the service life of the internal waterproof plastic film. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figure 1-3 As shown, the utility model provides a technical solution: a waterproof webbing, comprising a webbing body 1, the webbing body 1 comprising a plain weave layer 4 and a twill encryption layer 6, the plain weave layer 4 being arranged on the upper and lower sides of the twill encryption layer 6, a waterproof plastic film 5 being arranged between the plain weave layer 4 and the twill encryption layer 6; the plain weave layer 4 being formed by weaving polyester fiber and nylon fiber in warp and weft, the polyester fiber on the plain weave layer 4 being the warp yarn, the nylon fiber on the plain weave layer 4 being the weft yarn, the twill encryption layer 6 being formed by weaving polyester fiber and nylon fiber in warp and weft, the nylon fiber on the twill encryption layer 6 being the warp yarn, the nylon fiber on the twill encryption layer 6 being the The weft yarn, the plain woven layer 4, the waterproof plastic film 5 and the twill densified layer 6 are pressed together by a flat vulcanizing machine. Under the tightly woven structure of the plain woven layer 4, the deformation distance of the ribbon during pulling is limited by the tightly woven plain woven layer 4 to prevent the ribbon from being deformed too long, which causes the waterproof plastic film 5 to be deformed or torn, thereby weakening the waterproof effect. Furthermore, through the design of the twill densified layer 6, the waterproof plastic film 5 is twisted and torn when the ribbon is subjected to torsional pulling force, resulting in the loss of waterproof effect inside the ribbon, thereby solving the technical problem of low service life of the waterproof plastic film 5 inside the ribbon.

[0033] A step further, such as Figure 1 - Figure 3As shown: a nano-waterproof coating 3 is provided on the outside of the plain woven layer 4, and the nano-waterproof coating 3 is covered on the plain woven layer 4 by coating and curing. A silicone coating 2 is provided on the outside of the nano-waterproof coating 3, and the silicone coating 2 is covered on the nano-waterproof coating 3 by coating and curing. The plain woven layer 4 is waterproofed by the nano-waterproof coating 3. Since the nano-waterproof coating 3 can form a tiny nano-level coating, it can effectively prevent water molecules from penetrating into the inside of the ribbon, and under the action of the nano-waterproof coating 3, the ribbon is kept waterproof while ensuring its breathability. The nano-waterproof coating 3 is protected by the silicone coating 2 to prevent the nano-waterproof coating 3 from being worn during use, resulting in a weakening of the waterproof effect. Since the silicone material itself has good chemical resistance, it can resist the erosion of many chemicals, and the silicone coating 2 has excellent high temperature resistance and can usually withstand temperatures of up to several hundred degrees Celsius. This allows the ribbon coated with the silicone coating 2 to maintain stable performance in a high temperature environment and is not easily deformed or damaged, thereby solving the technical problems of external wear and waterproofing of the ribbon.

[0034] The above solution still has the problem that the two ends of the ribbon body 1 absorb water and collide to form a gap between the plain woven layer 4, the waterproof plastic film 5 and the twill dense layer 6, such as Figure 1 As shown: In this solution, waterproof plywood 11 is provided at both ends of the plain woven layer 4, the waterproof plastic film 5 and the twill dense layer 6. The waterproof plywood 11 completely covers and wraps the plain woven layer 4, the waterproof plastic film 5 and the twill dense layer 6. The waterproof plywood 11 clamps and fixes the two ends of the plain woven layer 4, the waterproof plastic film 5 and the twill dense layer 6 to prevent liquid from entering from both ends of the ribbon body 1 during use, causing the plain woven layer 4, the waterproof plastic film 5 and the twill dense layer 6 to expand after absorbing water, resulting in gaps between the plain woven layer 4, the waterproof plastic film 5 and the twill dense layer 6.

[0035] The above solution still has the problem that the ribbon body 1 has a waterproof dead corner, such as Figure 3 As shown: In this solution, the nano waterproof coating 3 is completely covered on the plain woven layer 4, the waterproof plastic film 5 and the twill dense layer 6, and the silicone coating 2 is completely covered on the nano waterproof coating 3. By completely covering the plain woven layer 4, the waterproof plastic film 5 and the twill dense layer 6 with the nano waterproof coating 3, the waterproof dead angle is reduced, the waterproof effect is improved, and the liquid is prevented from entering the interior of the plain woven layer 4, the waterproof plastic film 5 and the twill dense layer 6 through the side. Furthermore, under the action of the silicone coating 2, it is completely covered on the nano waterproof coating 3, and the nano waterproof coating 3 is more effectively protected.

[0036] Working principle:

[0037] like Figure 1-3As shown, first, the nano waterproof coating 3 is protected under the action of the silicone coating 2 to prevent the nano waterproof coating 3 from being worn during use, resulting in a weakening of the waterproof effect. Secondly, the plain woven layer 4 is waterproofed under the action of the nano waterproof coating 3. Since the nano waterproof coating 3 can form a tiny nano-level coating, it can effectively prevent water molecules from penetrating into the interior of the ribbon. Further, under the action of the plain woven layer 4, the ribbon is prevented from being subjected to lateral pulling force. The deformation distance during pulling is limited by the tightly woven plain woven layer 4, avoiding excessive deformation of the ribbon, resulting in a weakening of the waterproof effect after the waterproof plastic film 5 is torn. The design of the twill encryption layer 6 can also ensure that when the ribbon is subjected to torsional pulling force, the waterproof plastic film 5 is twisted and deformed to cause tearing.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
