First of all, natural fillers
1, buckwheat husk with moderate hardness: this is the most common pillow filler. Moderate hardness, good formability, good water absorption and light weight. The disadvantage is poor elasticity, and the pillow will make noise when the head and neck are moving, which may affect people who are prone to insomnia.
2. Paddy shell with good water absorption: It is better than buckwheat shell in shaping and water absorption, but it will be slightly heavier and there will be noise when people are active.
3. Molded rice bran skin: it has certain moldability, but the edge is easy to pierce the cloth, irritate the skin, and it is also prone to noise.
4, breathable fluffy down: down fiber has good resilience, and has the function of adjusting temperature and humidity, high permeability, and can provide a dry and comfortable "small environment" for the human body. Down pillows can't be washed. People with allergies had better avoid using this pillow to avoid respiratory discomfort.
Second, artificial fillers.
Many high-quality artificial fillers do not lose natural fillers in many aspects such as warmth retention, hygroscopicity and elasticity, and some have good antibacterial, mildew-proof and disease-prevention functions because of the characteristics of materials or additives.
1, Easy-to-clean ordinary man-made fiber: This filler is chemical fiber cotton wool, which is easy to wash, even can be washed by a washing machine, and can also be compressed and stored in a 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.
2. High-tech hollow fiber: Hollow fiber is a high-tech product and a composite material. It runs through one or several small holes in 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.
3. Latex filler that people with allergies can also use: Latex is a 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.
