How to measure the water absorption capacity and cleaning effect of Car Drying Towel?

The water absorption capacity and cleaning effect of car drying towels are two key indicators to measure their performance, which directly affect their effectiveness in daily use by car owners.

Water absorption capacity is one of the most important properties of car drying towels, which is directly related to the efficiency and effect of towels in the vehicle drying process. The measurement of water absorption capacity usually involves the following aspects:
Water absorption rate refers to the weight increase of the towel during the water absorption process. Generally speaking, towels with strong water absorption capacity can quickly absorb moisture from the surface of the car paint and reduce the time that water droplets remain on the car body. A common test method is to soak the towel completely in water, then pick it up and measure the weight increase of the towel. Water absorption rate is usually expressed as a percentage of the increase in the weight of the towel. The higher the water absorption rate, the stronger the water absorption capacity of the towel.
The water absorption rate of microfiber towels is usually between several hundred percent (that is, the weight of the towel can increase many times).
The water absorption rate of cotton towels is lower, usually between 100-200%.
Water absorption rate refers to how quickly a towel absorbs water, and faster absorption means that car owners can more efficiently remove water droplets when drying the car body. Towels with high water absorption rates are usually finer in fiber or have a special structural design, which can absorb water in a shorter time and avoid residual water droplets.
Water absorption capacity refers to the maximum amount of water a towel can hold after being saturated. Towels with high capacity can absorb more water in a single use, thereby reducing the need to wring the towel frequently during use. This indicator is usually related to the thickness and fiber type of the towel.
The fiber structure of the towel (such as weave and fiber length) has a direct impact on its water absorption capacity. For example, microfiber towels usually have better water absorption performance than other types of towels because the fibers are very fine and can provide a larger surface area. Towels with higher density usually absorb more water.
The cleaning effect of car drying towels is mainly reflected in two aspects: stain removal ability and leaving no residue. These factors are usually measured by the following methods:

A key aspect of cleaning effect is whether the towel can effectively remove stains, dust and scale from the surface of the vehicle. When using a dry towel, the surface of the towel needs to be fine enough to avoid scratches or stains from rubbing against the car paint. High-quality dry towels can usually remove surface contaminants smoothly during the wiping process without leaving any marks. The material and weave of the towel have a great influence on this.
Due to its fine fibers and mesh structure, it can effectively capture dust and water stains on the car surface, has a good cleaning effect, and is not easy to leave fine scratches when used.
Cotton towels are relatively soft and suitable for wiping the car body, but may not be as efficient as microfibers to clean some stubborn stains and are prone to leaving lint.
The cleaning effect of the towel also includes whether it can effectively avoid water marks or scratches during the wiping process. Water marks are usually caused by incomplete absorption of water by the towel during the wiping process, while scratches may be caused by the friction of tiny particles or fibers in the towel. To measure the cleaning effect of the towel, some light wiping tests can usually be performed on the surface of the vehicle to observe whether it can effectively remove water droplets or stains without leaving any visible marks.
You can choose to wipe different areas of the car body, especially those with slight contamination or water stains, to see if the towel can clean smoothly without leaving marks. Compare the cleaning effects of different brands or types of towels to see if they can achieve no water marks or scratches.
High-quality car drying towels usually use fine and uniform fiber weaves, which can avoid linting, fiber residue or stains when cleaning. Microfiber towels usually clean the car body surface better than traditional cotton towels due to their extremely fine fibers and powerful cleaning effect.
The softness of the car drying towel directly affects its effect during the wiping process. Soft towels can contact the car paint more gently, reducing the risk of scratches caused by friction, while better contacting water droplets and stains to help remove surface dirt. Harder or rough towels may scratch the car paint when wiping, causing scratches.

When choosing the right car drying towel, car owners need to consider these factors comprehensively to ensure that the towel can complete the drying and cleaning work efficiently and safely. At the same time, regular maintenance and correct use are also important factors in maintaining the performance of the towel.
