Problems solved by technology

Most of the currently commercially available swimming products are made of silica gel or plastic materials. For example, the Chinese invention patent with the notification number CN1202886C discloses "swimming goggles and their preparation process". Material, although the patent does not limit what kind of hard material, but it can be known that the hard material has no elasticity and has a certain degree of oppression on the body
Most of these materials are airtight and inelastic during use, causing slight discomfort to users during use
In addition, due to problems such as hardness, the user may not match the shape of the face, head, and feet during use, which will cause pressure on certain parts of the body, resulting in poor blood circulation and even danger. Some swimming equipment may slip when in contact with water

Abstract

The invention discloses a waterproof breathable novel material. The composition of the material adopts combination of cloth and silica gel; through processing and treating of an impregnating process, the waterproof breathable novel material can achieve the main functions of being breathable and water-tight. A preparation method for the waterproof breathable novel material comprises the following steps: firstly, dispersing and uniformly mixing vinyl silicone oil, fumed silica, vinyl MQ resin, hydrogen-containing silicone oil, a platinum catalyst and an inhibitor to obtain a mixture, and using n-heptane to dilute the mixture until solid content is 20%; then, impregnating polyester fiber and spandex blended knitted fabric into a liquid silica gel solution; taking out the knitted fabric to dry; and using a hot air drying channel to dry the knitted fabric, thereby preparing the waterproof breathable novel material. The waterproof breathable novel material solves the problem that most of a bathing suit and the like in the market at present are not breathable and are relatively great in hardness, have the conditions of being not matched with corresponding parts of a body in use, have slippage conditions in a process of being in contact with water, and the like. The waterproof breathable novel material has the advantages of being good in waterproof performance, good in comfort and breathability, and the like.

Description

technical field [0001] The invention relates to a waterproof and breathable material, in particular to materials used in swimming glasses, swimming caps, fins and the like. Background technique [0002] In the clothing industry, the fabrics of clothing are varied and changing with each passing day. But generally speaking, high-quality and high-end fabrics mostly have the characteristics of comfortable wearing, sweat-absorbing and breathable, noble vision, and soft touch. The choice of swimsuit also depends on the fabric and performance. A good swimsuit fabric is soft, durable and elastic, and the texture of the fabric is relatively dense. Not only swimsuits, but other swimming caps, fins, etc. should also be made of materials that are elastic, wear-resistant, safe, non-irritating to the skin, and have a long life. Most of the currently commercially available swimming products are made of silica gel or plastic materials. For example, the Chinese invention patent with the n...
