The Waterproof Fabric Itself Has A Waterproof Function

For outdoor travel to cope with changeable weather, waterproof clothes, pants and even shoes are very important. However, I believe many people are not particularly clear about the concepts of fabric waterproof and fabric water splashing prevention. Facing the increasing number of outdoor brands that claim that their products have waterproof function, they will have some doubts. Which fabrics are really waterproof? Why should products that already use Waterproof Fabric emphasize water splashing prevention?

Waterproofing of textile outdoor fabric usually refers to the waterproof function of fabric itself. After experiencing the initial tight fabric and coated waterproof fabric, waterproof fabric is now dominated by adhesive film fabric. The key to play waterproof role lies in the functional film used in the fabric.

At first, the adhesive film fabric with the largest market share basically uses PTFE (polytetrafluoroethylene) films, which belong to microporous films. The waterproof performance is expressed by the water pressure it can withstand, and is not 100% waterproof. According to European environmental protection research, PTFE materials will produce compounds harmful to the environment during manufacturing, landfill and incineration. In recent years, environmental protection circles have raised more and more doubts about PTFE materials, and some countries have begun to restrict the use of PTFE materials.

In addition, the complete waterproof of the garment is also closely related to the waterproof performance of the adhesive tape and zipper used at the seam, because the waterproof and water splashing prevention of the textile composite fabric refer to the functionality of the fabric itself, and the needle eye or zipper gap at the seam cannot achieve 100% waterproof without being treated.
