The Origin and Principle of Quick-dry Fabric

1.The origin of quick dry fabric

Quick-dry fabric means that when compared with clothing made of wool or cotton, it is easier to evaporate moisture and dry faster under the same external conditions.

2.The performance of quick-dry fabric

Some people think that quick-dry fabric is very mysterious, thinking that there are a lot of high-tech ingredients in it. In fact, most quick-dry fabrics are made of chemical fiber fabrics, but due to the different processing technology, they have all kinds of magical effects that ordinary clothes do not have. The quick-dry fabric has low water absorption and good air permeability, so it has a certain degree of water repellency. After being wet, it dries faster than ordinary clothes under the effect of body temperature or wind.

3.The principle of quick-dry fabric

For waterproof and breathable quick-dry underwear, from a technical point of view, the main principles are as follows:

(1)Use the difference between the smallest diameter of water droplets and the diameter of water molecules or air molecules. We all know a common sense that even the smallest water droplet must have a much larger diameter than water or air molecules. Then, if the pore size between the warp and weft of the fabric is controlled between the smallest diameter of water droplets and the largest diameter of water or air molecules, it can be achieved that water droplets cannot enter, and water and air molecules can flow unimpeded. Fabrics made by this method are usually called ultra-fine high-density fabrics or ultra-high-density fabrics.

(2)Using Micro Porous membrane. Fast-drying fabrics usually make the membrane's micropore diameter between the smallest diameter of water droplets and the largest diameter of water or air molecules, and then the membrane is combined with the outer fabric to give the cloth waterproof and breathable functions.
