Pillow, a sleep tool. It is generally believed that pillows are the stuffing that people use to sleep comfortably. According to modern medical research, the spine of the human body is a straight line when viewed from the front, but a curve with four physiological curves when viewed from the side. In order to protect the normal physiological curvature of the neck and maintain normal physiological activities during sleep, pillows must be used when sleeping. Pillows generally consist of a pillow core and a pillowcase. Pillows consist of a filler material enclosed in a fabric cover or shell. Covers are made of cloth, such as silk, known as the pillow case or pillow slip. Some pillows have a fancier cover called a sham which is closed on all sides and usually has a slit in the back through which the pillow is placed. Rectangular standard bed pillow cases usually do not have zippers, but instead, have one side open all the time. Often, a zippered pillow protector is often placed around standard pillows with the case in turn covering the protector. Fillers are chosen on the basis of comfort, resilience, thermal properties, cost and also for medical and ethical reasons. The most common synthetic fillers are materials derived from polymer fibers, such as polyester and memory foam. Synthetic fillers in general are inexpensive and in the case of memory foam can retain their form longer. Natural fillers have been used since antiquity. The most common are feathers, down, wool, latex, cotton (particularly in India), and buckwheat. More exotic materials have also been used including straw , wood, or stone. Down is usually the softer filler and offer good insulation, but is more expensive due to its relative scarcity. Down has been known to be plucked from live geese, but there are already cruelty-free certifications for down products. In India, traditional pillows are made with kapok, the fluffy, glossy fruit-fibres of the trees Ceiba pentandra and Bombax ceiba.
Latex pillows are made of the sap of rubber trees, and it is impossible to make latex pillows made of 100% pure latex. The latex content of latex pillows on the market is only 80%-97%. Because pure latex cannot achieve coagulation and fluffy effects, it needs to be artificially fermented with safe materials. Latex pillow has the characteristics of natural environmental protection, non-polluting, non-toxic, anti-allergic and so on. Designed according to ergonomic principles, it can effectively promote sleep, effectively prevent snoring, and is suitable for asthma patients. The latex pillow can effectively reduce the static electricity between the human body and the fiber. The honeycomb structure has good air permeability, and quickly dissipates the heat generated by the human body. The most convenient thing about latex pillows is that they can be washed with water. Natural latex pillows are easy to clean by hand. As long as they are dried with a fan after dehydration, or dried in an oven at low temperature, they will never be deformed. They are easy to maintain, foldable, and easy to collect. It is the most comfortable choice for the pursuit of healthy sleep.
A pillow case is something that wraps the pillow under the pillow cover, like a cloth pocket. Pillowcases are an important part of modern pillows. Ancient people did not use pillowcases. They used pillow cores and pillow covers. Modern pillows come in three common one-piece styles, Oxford (with a flat edge) and trim. All three types of pillowcases have an inner seal that secures the pillow, so that there is no need to implement some reinforcement measures on both sides. Cotton, cotton polyester and rayon can all be used to sew pillowcases, but the most comfortable pillowcase material is pure cotton, which is breathable and hygroscopic, and does not irritate the skin. Modern people also like to use silk pillowcases, also known as silk pillowcases. Silk is a good thing and has many reputations such as fiber queen and soft gold. More than 97% of silk is composed of animal protein and rich in 18 kinds of amino acids necessary for the human body. Silk is said to clean and maintain the skin and increase the vitality of skin cells.
