What is the principle of quick-drying clothes?

Outdoor quick-drying clothes generally require two properties: moisture absorption and quick drying. However, moisture absorption and quick drying are two concepts, and the detection methods are different and cannot be confused.

First, moisture absorption:

Moisture absorption mainly absorbs the sweat of the body through the capillary action of fibers. There are two ways to make fabrics: one is yarn and the other is assistant.

A. yarn, which is a modified polyester fiber. The cross section of this fiber is not round, but usually cross-shaped. Many crosses are crowded together, forming a capillary effect, which is easy to take away sweat. There are many kinds of irregular yarns in the world, such as C-shaped hollow yarn, W-shaped yarn and U-shaped yarn, but cross yarn is the most common.

Coolmax is more than 35% daily, which is suitable for daily life.

Coolmax is more than 50% active and suitable for light exercise activities.

More than 85% of Coolmax Extreme is suitable for extreme sports such as mountain climbing and rock climbing.

B. When dyeing, auxiliaries are added, and hydrophilic groups in the auxiliaries are grafted onto the fibers, so that the fabric has a relatively intuitive moisture absorption effect. Drop a drop of water on the cloth before putting the auxiliary. It may take a few seconds for the fabric to penetrate all the water droplets, but after you add additives, it will penetrate all the water droplets within one second. This is the contrast. Therefore, most moisture-absorbing and quick-drying fabrics, even if the above-mentioned cross-shaped yarns are used, will still use additives for further processing.

However, additives are not washable, and the effect will decrease after repeated washing. And most importantly, don't use silicone oil fabric softener for washing. They are mutually exclusive.

Quick dry:

Why can fabrics dry quickly? Because the component is hydrophobic, its fiber structure can't lock water. The best quick-drying fiber should be polypropylene. This kind of thing is absolutely amazing if it is not difficult in production technology. This kind of polypropylene fiber is lightest, most hydrophobic and warmest. This product has been developed before, and it is quite interesting. Now there are some big-name quick-drying clothes with some polypropylene fibers on them, which are really rare.

Professional outdoor sports quick-drying clothes have no natural fibers such as cotton and linen. Cotton and linen can absorb water and lock water, and it is not easy to dry, so we have to abandon it. It is unprofessional to use cotton and linen ingredients and promote quick drying.

The fabrics of quick-drying clothes and trousers on the market are mostly polyester or nylon.
