Rice husk with good water absorption is better than buckwheat husk in shaping and water absorption, but it will be slightly heavier and make noise when people are active.
The molded rice bran skin has certain formability, but its sharp edge is easy to pierce the cloth, irritate the skin and make noise.
Breathable fluffy down fiber has good resilience, temperature and humidity control function and high air permeability, which can provide a dry and comfortable "small environment" for human body. Down pillows can't be washed. People with allergies had better avoid using this pillow to avoid respiratory discomfort.
Many high-quality artificial fillers do not lose natural fillers in many aspects such as heat preservation, moisture absorption and resilience, and some have good antibacterial, mildew-proof and disease-prevention functions because of the characteristics of materials or additives.
Easy-to-clean ordinary man-made fiber This filler is chemical fiber cotton wool, which is easy to wash, even can be washed by washing machine, and can also be compressed and stored in vacuum compression bag, and the price is cheap. However, the permeability of chemical fiber cotton wool is not very good, and it is easy to form balls and agglomerate after being used for a long time, thus lacking elasticity and shortening life.
High-tech hollow fiber hollow fiber is a high-tech product and a composite material. One to several air holes run through ordinary man-made fibers with poor air permeability, so that each fiber can store more air. The pillow made of this filler greatly improves the elasticity, warmth retention, bulkiness and service life. Because of the different materials and additives, some of them also have health care and medical functions.
Latex filler, which can also be used by people with allergies, is a kind of filling material made of natural rubber through foaming process. Because it comes from pure natural materials, it is non-toxic and tasteless, and has no adverse effects on the human body. The whole structure of latex avoids the interference of fine fibers to human body, and is especially suitable for allergic people and asthma patients. In addition, latex has good air permeability, is not easy to deform and is easy to shape, and can provide suitable support for cervical vertebrae. However, due to raw material factors, the price of latex pillows is relatively expensive.
