A pillow made of a slow rebound material is not the function of increasing peoples memory, but because the pillows that are often used can form the inherent shape of the head and neck, most of which are slow backpack pillows.So what are the characteristics of memory pillows? What are the main points of buying?
1. Absorb impact.When the pillow is on it, it feels like floating on the water or clouds, and the skin feels like there is no oppression; also known as zero pressure. Sometimes when we use the usual pillow, there will be a phenomenon of compression of the auricle, but it will not appear to use a slow rebound pillow.This situation.
2. Memory deformation.The ability of automatic shaping can fix the skull and reduce the possibility of falling pillows; the ability to automatically shaped can be properly filled with the shoulder gaps to avoid common problems of leakage in the shoulders, which can effectively prevent cervical spine problems.
3, anti -bacterial and anti -mites.Slowly bomb sponge inhibit the growth of mold, removes the irritating smell caused by the growth of mold breeding, and it looks more prominent when there is sweat saliva.
4, breathable and moisture.Because each cell unit is connected to each other, the hygroscopic performance is excellent, and it is also breathable.
5, relieve stress.Automatically fit according to the human curve, release contact facial muscles and physical and mental stress.
Purchase
First, whether it is pure material.Whether the pillow is made of 100%polyurethane, whether the talc powder is added to increase the density? This is the secret of the industrys production technology and high density.More than 90%of the slow -back pillows in the Chinese market are produced in non -pure materials, so density indicators are becoming difficult to measure the true quality of pillows.
2. Whether the security check is passed: the slow -to -rebound material is a chemical item, which is harmful in terms of chemical composition. Therefore, it must be controlled by its safety indicators in production.Whether a pillow is appropriate depends on whether his safety testing indicators pass? At present, the slow rebound product detection includes a toxic and harmful substance detection and pure material testing.
Third, density: density is one of the basic indicators of high -end slow -back bullet material. Generally, the density of polyurethane density of molding process can achieve 70 ~ 150D, and the cutting process can achieve 40 ~ 100D. Due to the difference in technical bottlenecks and equipment,The density of polyurethane produced in China is generally lower than 100D, and the maximum foreign abroad can reach 150D. Secondly, even products with the same density will be very different. It is mainly caused by different formulas, processes and raw materials.The bullet material must be high -density, but only high -density is not necessarily high -end material.
Fourth, rebound time: rebound time is also called maintenance ability. Generally, the slower, the better the decompression ability.Domestic memory cotton rebound time is generally 3-5 seconds, and imported memory pillows have more than 10 seconds.
Fifth, manufacturing process: There are two types of manufacturing processes: cutting and molding.Cutting is to buy the sponge slowly and cut into a pillow, because the molding is cut by cutting rather than mold+auxiliary, and no other auxiliary agent can only achieve 40-70D even if the density of pure material polyurethane can be achieved.The molding is made of a series of processes such as adding auxiliary agent, foaming, and mold suppression. Because other additives, including foam, soft and other chemicals, the density increases to about 70-90d,Feel good.Remind everyone that the life of the pillow has nothing to do with the craftsmanship.
6. Feeling and temperature sensing: The relationship between the feel and the density of the temperature and the pillow is not much related, mainly because the factorys mature process is created (the different decisions of adding the auxiliary agent according to the environment), the high -end slow -back sponge sponge feels very comfortable.It feels like pinching the dough, and it is a bit stiff if you feel a little bit stunned if you feel a little slow.
7. Life life: Polyurethane memory cotton pillows are mainly related to whether pure material polyurethane and whether it is high -end polyurethane. If it is a pure material imported polyurethane, it should not be deformed for more than 5 years, but if it is added to the density and weight addingTalcum powder and other raw materials, poor pillow quality, usually can only use 1 to 2 years.
