Brief Introduction And Difference Between Waterproof Fabric And Water Repellent Fabric

< p > in the early days of waterproofing fabrics, the most commonly used adhesive film fabrics are PTFE (polytetrafluoroethylene) films, which belong to the microporous membrane. The waterproofing performance is expressed by the water pressure which it can withstand, and is not 100% waterproof. In comparison, another kind of thin film non porous hydrophilic membrane used by more and more brands in recent years is not only porous to 100% waterproof, which makes the product waterproof performance more reliable, but some non porous hydrophilic membranes are also favored by more people in the industry because of their environmental protection and harmless properties to human body. This material does not contain PTFE components, can directly contact the skin, and can be recycled as recycled PET plastic. < /p >
< p > usually, these fabric manufacturers do not sell films directly to < a target= "_blank" href= "//www.sjfzxm.com/" > strong > clothing < /strong > /a > brand. They combine the film with other materials to form composite fabric through the paste process (as shown above, the middle layer is thin film), and the brand can only directly produce waterproof clothing products by buying these composite fabrics. These fabrics are not waterproof, such as polyester fiber, nylon and so on, so when we wear waterproofing clothing, we will see that the water is seeping into the garments, just like ordinary fabrics, but the inner layer of the clothing is dry, and there is no water to permeate. This is the waterproof film that is played in the middle of the composite fabric. < /p >
< p > if water is dispersed into small droplets on clothing and then slipped down, it is usually because the < strong > a href= "http://cailiao.sjfzxm.com/Matertial/show/machine_index.aspx" > fabric > /a > /strong > after water splashing is treated, anti splashing treatment is actually a special treatment covering the surface of the fabric, usually adding DWR to the fabric finished product, so as to obtain durable water repellent property. The purpose of using DWR coating is that when water drops to the surface of the garment, it can form small droplets or slide directly from the surface of the garment, thus preventing the fabric from absorbing moisture. At the same time, it also makes the oil stains on the surface of the garment easier to remove. Most waterproof clothing uses this DWR anti splashing treatment, and the advantage of DWR treatment is that it can not absorb moisture on the surface of the garment, so as to ensure that the waterproof fabric can achieve good air permeability, so that the human body has a very good feeling of wearing. < /p >
< p > in short, waterproof fabrics can basically achieve 100% waterproofing, but in order to get more comfortable wearing experience and make these waterproof fabrics play a good ventilation effect, DWR anti splashing treatment is also necessary. In addition, the complete waterproof of clothing is closely related to the properties of strong, > a href= "http://cailiao.sjfzxm.com/Matertial/show/material.aspx", "waterproof" /a "/strong", which are used in the rubber accessories and zippers at the juncture, because the waterproof and splashing water of fabrics are the functional properties of the fabric itself, and the gaps between the needles or zippers at the juncture can not reach 100% waterproof if not treated. < /p >
