Many people have misunderstandings or understandings about “Fiber cotton and hollow cotton“. Next, let the editor take everyone together to share with friends and explore the “Fiber cotton and hollow cotton” Hollow cotton” knowledge…
[Fiber cotton]
Fiber cotton, first of all, it is not cotton in the traditional sense. Although it is called fiber cotton, it just looks like cotton in appearance. In fact, it is a special ultra-fine polyester chemical fiber material.
The so-called four-hole cotton, seven-hole cotton, nine-hole cotton, and ten-hole cotton on the market are just this kind of fiber cotton, but they have different names.
Why is this kind of multi-hole fiber cotton called “hole”?
Mainly refers to viewing polyester fiber slices under a high-power microscope. The number of holes in its fiber cross section is usually called four holes, seven holes, nine holes, ten holes, etc.
The more holes the fiber has, the better it is for breathability, warmth retention, looseness, and the softer it appears. Because air is stored in the cavities, the higher the number of cavities, the greater the amount of air. The more sufficient the air content is under the conditions of the insulation layer, the better its breathability and thermal insulation properties will be.
At the same time, the more air is filled in the cavity, the more channels there are for compression and rebound, and the more looseness and softness can be enhanced.
[Hollow cotton]
Using high-quality polyester and three-dimensional crimped hollow fiber with excellent performance, U-shaped hollow fiber and ES fiber as raw materials, it is a high-warm cotton product after finishing treatment. The fiber raw material is polyester.
Highly warm cotton products made of high-quality polyester
Hollow quilts are widely used and have good elasticity. It has good looseness, good warmth retention and breathability. The product has good shape retention under pressure, prevents knotting and deformation, is lightweight, has strong tensile strength, is washable, is not afraid of insects, is mildew-proof and moisture-proof, and has a warmth retention rate 60% higher than cotton fiber. Above, the service life is more than 3 times longer. Fiber cotton and hollow cotton
However, after being used for a long time, it easily deforms and forms lumps. It lacks elasticity and makes the pillow uneven. Especially the inferior chemical fiber pillows produced by some small manufacturers have black core cotton in some parts.
