1. PP cotton, this kind of filler is one of the longest seen in the market. It has an irregular shape. Some feel slippery and some feel astringent. This is due to the fact that the amount of silicone oil added is not the same. When choosing, it depends on the whiteness of the cotton. The white is relatively better, and the gray material is generally recycled and recycled. In addition, the cakes that are not easy to cake are better, you can try it by tearing it with your hands. It is easy to tear and better (that is, the fluffy is good). When you make the pillow core yourself, you must tear it up before filling it with cotton. Do not use peculiar smell, do not use other powdery layered things falling off. But this kind of cotton, after a long time, is not easy to pat loose and easy to agglomerate.
2. Pearl cotton, which is also a kind of filler that can be seen in the market. It is in the form of pearl particles. Because it is a small particle, it is not easy to agglomerate and has better elasticity. The color and bulkiness can confirm whether it is good or bad. As with the above identification method, the particles should be as uniform as possible. The cost-effectiveness of this cotton is relatively high. The time can be longer than that of PP cotton. When it is usually flat, it will get fatter with pats.
3. Superfine fiber (2.5D cotton or 3D cotton). The appearance of this cotton is very similar to PP cotton, but it feels very soft, not easy to agglomerate, and has poor elasticity. Pillows of the same size are more than the above two types of cotton. Charge about 50%. The price is also high, and it is generally not available in the market. When some customers have to do it, we will add PP cotton in a certain proportion to improve its bulkiness and weight. So if a store says that he can provide it to you, be very careful not to be fooled.
4. Cotton. In the past, Chinese people also filled cotton. Because cotton does not have very good elasticity, it is generally no longer used as a filling for pillows.
