Manufacturing method and structure of airtight diving suit

The present invention provides a method for manufacturing a wetsuit and a structure thereof, and more particularly to a method for manufacturing a gas-tight wetsuit and a structure thereof.

Under the high economic development, the airtight effect of wetsuits has always been a part of people's attention. In addition to special airtight certification, special clothing products will not consider the weight and dry comfort of the wearer's materials. Sex.

And the manufacture of traditional wetsuits is mostly made of polyester or polyamide fibers, which are combined with synthetic rubber sponges to form the material of the wetsuit. However, traditional wetsuits have a certain moisture content due to the material of the fabric, which causes a cold feeling due to heat balance in the human body, especially when diving in a colder climate, which makes the human body feel cold, especially the deeper the sea water, the lower the temperature. Therefore, it is necessary for the wetsuit to provide a moderate warming effect. In view of this, the development of a wetsuit with high waterproof and warmth effect, allowing the diver to dive in a lower temperature area, still maintain the proper body surface temperature, has become the focus of research and development in this field.

The invention provides a method for manufacturing a wetsuit with airtight function, which can prevent water from penetrating into the wetsuit and has high waterproof and warmth keeping effect. Compared with the traditional bulky wetsuit, the wetsuit of the invention has the light weight effect and the softness and toughness, so that the diver can feel comfortable and comfortable when wearing it.

The invention provides a method for manufacturing a hermetic wetsuit, which comprises the steps of: coating a gas-tight resin on the surface of a polyester fabric to form an outer layer structure, and cutting the airtight resin into a solid butyl rubber. The block is formed by mixing with toluene. A liquid butyl rubber was coated on the surface of the nylon cloth to form an inner layer structure. The outer layer structure is combined with the inner layer structure to form a laminated structure, and the laminated structure is subjected to a sulfurization reaction.

The present invention further provides a structure of a hermetic type wetsuit comprising an outer layer structure and an inner layer structure, wherein the outer layer structure is a plurality of layers of a gas-tight resin layer disposed on a surface of the polyester fabric, and the airtight resin layer comprises butyl rubber. And toluene. The inner layer structure is a layer of a butyl rubber layer provided on the surface of the nylon cloth. Among them, the airtight resin layer of the outer layer structure is bonded to the butyl rubber layer of the inner layer structure.

For a better understanding of the features and technical aspects of the present invention, reference should be made to the accompanying drawings.

Referring to FIG. 1 and FIG. 2, the present invention provides a method for manufacturing a hermetic wetsuit, which comprises the following steps. First, as described in step S100, on the surface of the polyester fabric 12, a multi-layer coating method is adopted. The airtight resin is applied to the surface of a high denier polyester fabric 12 to form an outer layer structure 1. The airtight resin is prepared by cutting a solid butyl rubber into fine blocks and mixing with toluene. Next, as described in step S102, a low-denier nylon cloth 22 is taken, and a multi-layer liquid butyl rubber is coated on the low denier nylon cloth 22 to form an inner layer structure 2. As described in step S104, the outer layer structure 1 and the inner layer structure 2 are combined with each other to form a laminated structure, and then, as described in step S106, a vulcanization apparatus (for example, a continuous vulcanizer for special rubber) is used for the laminated structure. The vulcanization reaction is carried out, and the airtight type wetsuit of the present invention is obtained at the end of the process.

More specifically, in the present invention, the butyl rubber having airtight properties is added and applied to the material of the wetsuit, and then the vulcanization reaction is carried out to obtain the airtight type wetsuit of the present invention, and thus the present invention is manufactured. The airtight wetsuit is highly airtight. The manufacturing method of the hermetic wetsuit of the present invention is detailed as follows: First, a polyester fabric 12 is provided, which is a non-absorbent high denier polyester fabric 12. As described in step S100, on the surface of the polyester fabric 12, the airtight resin is coated on the surface of the polyester fabric 12 by a multi-layer coating method, thereby forming a multilayer structure on the surface of the polyester fabric 12. The airtight resin layer 11 is used. Therefore, the airtight resin layer 11 and the polyester fabric 12 are bonded to each other to form an outer layer structure 1, which has an airtight property.

The method for preparing the gas-tight resin is to cut the solid butyl rubber into a fine block and use toluene as a solution, and cut the ratio of the solid butyl rubber to the toluene by 40%:60% by weight. The fine solid butyl rubber is placed in toluene to dissolve and mix, and the solid butyl rubber cut into fine pieces is stirred with toluene for about 10 to 20 hours, the operating temperature is about 90 to 150 ° C, and the viscosity is adjusted. About 40,000 to 80,000 cps, after which a suitable bridging agent such as sulfide or peroxide can be added, and the bridging agent accounts for about 3% to 8% by weight of the airtight resin, that is, the gas-tight resin is completed. preparation. The prepared airtight resin is applied to the surface of the polyester fabric 12 by a multi-layer coating method, thereby forming a gas-tight resin layer 11 having a multilayer structure on the surface of the polyester fabric 12, which is airtight. The resin layer 11 is combined with the polyester fabric 12 to form an outer layer structure 1.

Next, as described in step S102, a nylon cloth 22 is taken as a low-denier nylon cloth 22 having wear resistance properties. The liquid butyl rubber is applied to the surface of the nylon cloth 22 by a multi-layer coating method. The liquid butyl rubber has a viscosity of about 10,000 to 30,000 cps, and the coating operation temperature is about 90 to 150 ° C. A butyl rubber layer 21 is formed on the surface of the nylon cloth 22, and the butyl rubber layer 21 is combined with the nylon cloth 22 to form an inner layer structure 2 having a property of blocking water.

Thereafter, as described in step S104, the outer layer structure 1 and the inner layer structure 2 are superposed on each other to form a laminated structure. As described in step S106, the vulcanization apparatus (for example, a continuous vulcanizer for special rubber) is used to perform a co-vulcanization reaction on the laminated structure, the vulcanization temperature of the reaction is about 100 to 180 ° C, and the vulcanization time is about 10 to 30 minutes curing pressure of about 50 to 100 kg / cm ^2, i.e., the end of the process for producing gas-tight to complete the wetsuit.

The present invention further provides a structure of a hermetic type wetsuit comprising: an outer layer structure 1 which is a gas-tight resin layer 11 which is disposed on a surface of a polyester fabric 12 in multiple layers, and the airtight resin layer 11 includes butyl rubber and toluene, and may further include a bridging agent, and the inner layer structure 2 is a butyl rubber layer 21 which is provided in a plurality of layers on the surface of a nylon cloth 22. Among them, the airtight resin layer 11 of the outer layer structure 1 is bonded to the butyl rubber layer 21 connected to the inner layer structure 2.

In summary, the present invention has the following advantages:

1. The wetsuit made by the method for manufacturing the airtight wetsuit of the present invention has a highly airtight function because of the addition and application of butyl rubber to the material of the wetsuit, thereby preventing water from penetrating into the diving. The clothing allows the diver to wear the wetsuit while diving, which is highly waterproof and warm.
