\n When traveling outdoors to cope with changing weather, waterproof jackets, pants and even shoes are very important. However, I believe many people are not particularly clear about the two concepts of waterproof fabrics and water-repellent fabrics. Faced with the increasing number of people claiming that their products are waterproof When choosing a functional outdoor brand, you may have some doubts about which fabrics are used in clothing that are truly waterproof. Why do products that already use waterproof fabrics emphasize that they have been treated with water-repellent treatment? \ufffd\u5c0f\u7f16\u5c31\u4e3a\u5927\u5bb6\u8fdb\u884c\u4e00\u4e2a\u7b80\u5355\u7684\u533a\u522b\u4ecb\u7ecd\ufffd \ufffd<br \/

\n Fabric waterproofing usually refers to the waterproof functionality of the fabric itself. After the initial compact fabrics and coated waterproof fabrics, waterproof fabrics are now mainly pasted film fabrics. The key to exerting the waterproof effect lies in the materials used in the fabrics. functional films \ufffd<br \/
\n <br \/
\n The adhesive film-type fabrics that initially occupied the largest market share are basically made of PTFE (polytetrafluoroethylene) films. This type of film is a microporous film. The waterproof performance is expressed by the water pressure value it can withstand, which is not 100 % waterproof, and according to European environmental research, PTFE materials can produce environmentally harmful compounds when manufactured, landfilled and incinerated. \ufffd\u8fd1\u4e9b\u5e74\uff0c\u73af\u4fdd\u754c\u5bf9PTFE\u6750\u6599\u7684\u8d28\u7591\u58f0\u97f3\u8d8a\u6765\u8d8a\u591a\uff0c\u90e8\u5206\u56fd\u5bb6\u5f00\u59cb\u9650\u5236\u4f7f\u7528PTFE\u6750\u6599\ufffd Landfilling and incineration are the main methods of domestic waste treatment in the world, and these two treatment methods will produce perfluorinated compounds when processing PTFE materials. Fluorides will pollute the atmosphere and land. Due to the long period of natural decomposition of fluorides, so Environmental pollution caused by PTFE materials will be long-lasting and long-lasting In comparison, another kind of film that has been adopted by more and more brands in recent years – non-porous hydrophilic film is not only non-porous itself and 100% waterproof, making the product's waterproof performance more reliable, some non-porous hydrophilic films are more It has been updated because of its environmentally friendly and harmless characteristics. Industry insiders are optimistic that SympaTex? film, which is a molecular compound of polyether and polyester, contains absolutely no PTFE (polytetrafluoroethylene) components, can directly contact the skin, is harmless to the body, and can be recycled like PET plastic bottles.

\n Usually, these fabric manufacturers with film technology do not directly sell films to clothing brands. They use the pasting process to combine the film with other fabrics to form a composite fabric (as shown in the picture above, the middle layer is a film). The brand only needs Purchase these composite fabrics to directly make waterproof clothing products The fabrics used to combine with the film are not waterproof themselves, such as polyester fiber, nylon, etc., so when we wear waterproof clothing and encounter wet weather, we will see water seeping into the clothing, just like clothing made of ordinary fabrics. , but the inner layer of the clothing is dry and no water seeps in. This is the role of the waterproof film in the middle of the composite fabric. \ufffd<br \/

\n What we see when water disperses into small droplets on clothing and then slides off (as shown in the picture above) is usually because the fabric used has been treated with water-repellent treatment. The anti-repellent treatment is actually a special layer covering the surface of the fabric. Treatment, usually adding DWR (Durable Water Repellency) when finalizing the finished fabric, to obtain durable water repellent properties \ufffd\u4f7f\u7528DWR\u6d82\u5c42\u7684\u76ee\u7684\u662f\u6c34\u5728\u6ef4\u843d\u5230\u670d\u88c5\u8868\u9762\u7684\u65f6\u5019\u53ef\u4ee5\u5f62\u6210\u5c0f\u6c34\u73e0\u6216\u8005\u76f4\u63a5\u4ece\u670d\u88c5\u8868\u9762\u6ed1\u843d\u4ece\u800c\u963b\u6b62\u9762\u6599\u5438\u6536\u6c34\u5206\uff0c\u540c\u65f6\uff0c\u4e5f\u4f7f\u5f97\u9644\u7740\u5728\u670d\u88c5\u8868\u9762\u7684\u6cb9\u6c61\u7b49\u66f4\u5bb9\u6613\u88ab\u9664\u53bb\ufffd Most waterproof clothing uses this kind of DWR water-repellent treatment. The advantage of using DWR treatment is that the surface layer of the clothing does not absorb moisture, thereby ensuring that the waterproof fabric can achieve good breathability, so that the human body can wear it very well. feel \ufffd<br \/

\n It is worth mentioning that DWR water-repellent treatment is not permanent, but correct washing and ironing methods can extend the effect of DWR water-repellent treatment. And if your clothing loses its water-repellent effect, don\u2019t worry. Currently DWR coating restorers are available on the market \ufffd<br \/
\n <br \/
\n So you can see that clothing using waterproof fabrics can basically meet the functional requirements of 100% waterproof (PTFE film products under certain conditions, non-porous hydrophilic membrane under any conditions), but in order to obtain a more comfortable wearing experience , so that these waterproof fabrics can exert a good breathable effect, DWR water-repellent treatment is also necessary. \ufffd<br \/
\n <br \/
\n In addition, the complete waterproofing of clothing is also closely related to the waterproof performance of the taped strips and zippers used at the seams, because the waterproof and water-repellent properties of the fabric refer to the functionality of the fabric itself, the needle holes at the seams or the gaps in the zippers Clothes cannot be 100% waterproof without treatment \ufffd<\/p<\/p>\n
