How absorbent are microfiber car towels?

Water absorption principle
1. Structure of ultrafine fibers:
The diameter of ultrafine fibers is usually around 0.4 microns, which is much finer than the diameter of human hair (about 75 microns). This extremely fine fiber increases the number of fibers per unit area, thereby greatly improving the water absorption capacity.
The gaps between the ultrafine fibers form a large number of capillaries that can quickly absorb and retain water.
2. Large specific surface area:
Because the fibers are extremely fine, the specific surface area (surface area occupied by fibers per unit mass) of microfiber towels is very large. A large specific surface area means more contact points, which enhances the water absorption performance.
3. Capillary effect:
The capillary effect refers to the phenomenon that liquid rises or falls in a tiny tube due to surface tension. The gaps between the microfibers form many tiny capillaries that can quickly absorb water and store it inside the fibers.

Water absorption performance
1. Water absorption:
The water absorption of microfiber towels can usually reach 7 times or more of their own weight. This means that a 100-gram microfiber towel can absorb 700 grams of water.
In contrast, ordinary cotton towels can usually only absorb 2-3 times their own weight.
2. Water absorption speed:
The microfiber towel absorbs water very quickly and can absorb surface water almost instantly. This makes it very efficient when wiping the surface of the car, and can quickly remove water stains and stains.
3. Drying speed:
Although the microfiber towel has a strong water absorption capacity, due to its special fiber structure, water can quickly diffuse between the fibers, which speeds up the evaporation of water. Therefore, the microfiber towel can dry relatively quickly after use, reducing the chance of bacterial growth.
Practical application
1. Car body cleaning:
Microfiber towels are very suitable for wiping car bodies. They can quickly absorb water without leaving water marks and keep the car body bright.
2. Glass cleaning:
For car glass, microfiber towels can easily remove water stains and stains to ensure a clear view.
3. Interior cleaning:
When cleaning the interior of the car, microfiber towels also perform well, and can effectively absorb moisture and dust from surfaces such as seats and dashboards.
Summary
The water absorption of microfiber car towels is mainly due to their unique fiber structure and high specific surface area, which can quickly absorb a large amount of water and dry quickly. These characteristics make it an ideal choice for car cleaning, not only improving cleaning efficiency, but also protecting the paint and interior surfaces.
