When you mention the chemical fiber quilt, you will say how many holes the quilt is. Everyone has always thought that the number of holes is more. The better the quilt. So that the final is from a single hole, four holes, seven holes, up to ten holes, eleven holes. even more.
What is better with porous ones? Is the more holes the more the better?
First, let's look at what is a porous fiber: Porous fiber - slender as silk, magnified 300 times or more, it can be clearly seen that there are many tiny holes in the cross section of the fiber. A plurality of cavities are formed inside the fiber.
What are the benefits of porous fiber? We can analyze from the following aspects:
1. The air is an excellent insulation material when it is not flowing. It contains a large amount of non-flowing air in the voids of the ten-hole fiber, so the quilt made of the fiber is still outstanding.
2. Due to the large number of voids in the fiber, the specific gravity of the fiber is smaller. The quilt made of the fiber is softer and more comfortable.
3. As the voids increase, the surface area of ​​the fibers increases correspondingly, and the ability of the fibers to absorb harmful gases and moisture in the nest is enhanced.
Therefore, the porosity is well-founded. But is the more holes the better? We can imagine that a piece of round wood has a hole drilled in it, which can be a large hole. It can be said that the void ratio is large. However, when drilling ten holes, in order to make each hole a pair independent, each hole must have its own hole wall. These holes have a certain volume of thickness. This void rate is not as good as a hole.
Therefore, based on the analysis of the advantages of the above porous and the calculation of the void ratio, we can say that the more the holes, the better.
