Is there a dry towel on the table instead of rubbing it?


There is water on the table. At this time, wipe it directly with a dry towel. You will find that the water is only flattened where the towel is. The really effective way is to soak the towel with water, then wring it out hard, then wipe the table, the water on the table is sucked to the wipe. Why do dry towels not dry?
Wiping the table is actually the process in which the textile is in contact with water and the capillary is used to absorb the water. Some characteristics of the towel itself play a key role in the water absorption process: such as the surface area and thickness of the towel; the material of the towel, usually, the cotton towel absorbs water better than the chemical fiber; the technical method of textile, if used in textile The fiber is more absorbent.
We assume that the factors mentioned above are consistent, and the dry towel rubs the same tabletop with a towel that has been wrung out after dampening. The dry towel fiber is filled with air, and the water cannot enter the fiber smoothly due to the blockage of the air cushion. Secondly, the dry towel is in a dehydrated state, the fiber shrinks and shrinks. Due to the characteristics of the textile, the surface of the fabric becomes irregular. Although the fiber shrinkage makes the pore diameter narrow, it is more favorable for water absorption, but some pores are caused by residual dirt. Even, causing blockage and hindering the occurrence of capillary phenomenon, thereby affecting water absorption. If we soak the towel in a lot of water, the air in the pores of the towel is squeezed out. Then wring it out, the towel is compressed and deformed during the extrusion process, so there may be negative pressure in some micro-structure holes in a short time, and it will be inhaled immediately when it comes into contact with water, so it will be dried more.
