First, the purchase method of space memory cotton pillow
1, whether it is pure or not. Is the pillow made of 100% polyurethane, and is talcum powder added to increase the density? This is the secret of the production technology and high density of an industry. Pon pillows remind everyone that at present, more than 90% of the slow rebound pillows on the domestic market are not made of pure materials, so the density index is gradually difficult to measure the real quality of pillows.
2. Whether it passed the security check. Slow-rebound materials, belonging to chemicals, are harmful to some extent in terms of chemical composition, and their safety indicators need to be controlled in production. Whether the volatilization of toxic and harmful substances with slow rebound is fully exerted depends on whether a pillow is suitable and whether its safety detection index is qualified. At present, the detection of slow rebound products includes the detection of toxic and harmful substances and the detection of pure substances.
3. Density: Density is the basic index of slow rebound materials. If the density of the memory pillow is kept at 70-90 in the molding process, it is a high-density product. The pon pillow reminds everyone that the polyurethane density can be 70- 100 in general molding process and 40-60 in cutting process. If it exceeds this range, it may be fake. There is a density of 130- 150 in the market, which is almost unrealistic for pure polyurethane production enterprises. The only possibility is to add other things, such as talcum powder, which is heavier than polyurethane. From the perspective of a professional polyurethane sponge technician, 1 10 density pure polyurethane is ok, but others are not. In addition, even products with the same density will have great differences, which are mainly caused by the differences in formula, technology and raw materials. That is to say, the high-grade slow-rebound materials in molding practice must be high-density, but only the high-density materials are not necessarily high-grade materials, but the higher the density, the better (the high density of space cotton refers to the degree above 85D), and can maintain the characteristics of air permeability and fit the human body. TEMPUR pillow density is limited to 950G to 100D. For example, if the memory cotton of the pillow is higher than 100D, the air permeability of the material will start to decrease and the pillow core will gradually harden. In addition, the density of slow rebound pillows produced by cutting method can only reach 40-70. The disadvantage of this method is that the surface feel is not smooth enough, because there is no liquid assistance in the molding process, but the cutting process is more environmentally friendly and practical.
4. Rebound time: Many consumers think that the longer the rebound time, the better. This is a misunderstanding. Pon pillow reminds everyone that the better rebound time is about 3-5 seconds. Too short, no slow rebound effect; Too long will make the body stiff.
5. Manufacturing process: There are two manufacturing processes of slow rebound: cutting and forming. Cutting is to buy a finished slow-rebound sponge and cut it into the shape of a pillow. Because the molding is based on cutting rather than die+additives, even pure polyurethane can only achieve a density of 40-70 without adding other additives. Molding is made by adding additives, foaming, molding and a series of processes. Because other additives are added, including chemical additives such as foaming and softening, the density is increased to about 70-90, and the hand feel is good. Pon pillows remind everyone that the service life of pillows has nothing to do with technology.
6. Handfeel and temperature sensing: Handfeel and temperature sensing have little to do with pillow density, mainly because the technology of the manufacturer is mature (depending on the difference and amount of additives added in the environment). Advanced slow rebound sponge feels very comfortable, and it feels like kneading dough when pinched. Almost slow rebound will either feel a little awkward or stiff. At the same time, this kind of high-grade slow rebound also has good temperature sensitivity, which will soften and harden with the change of temperature, and you can see fingerprints when you put your hand on it without giving pressure;
7. Service life: pon pillow reminds everyone that polyurethane memory cotton pillow is mainly related to whether it is pure polyurethane or high-grade imported polyurethane. If it is pure imported polyurethane, it should not be deformed for more than 5 years. However, if talcum powder and other raw materials are added to increase the density and weight, the quality of the pillow is poor, and it can only be used for 1-2 years.
Second, the brand recommendation of Space memory cotton
1, 365 Sleep
As a brand of home and fashion products, 365sleep mainly focuses on sleeping and related products for the middle class. 365sleep advocates a simple and decent lifestyle. In this flashy atmosphere, the ideal sleep state of modern urbanites can be completed.
2. Doctor of Sleep
Dr. AiSleep Sleep is a truly natural and green high-tech sleep system brand specially designed for Asians. Dr. Eslip is not only a representative of scientific sleep, but also a model of healthy life. Dr. Sleeping Love is not only a brand, but also a warm life tip.
3. Neumann
Neumann Industries (China) was established in 1988. The core technology of its products comes from American space science and technology, and the raw materials and production technology are in the same strain as American quality. Because of its excellent performance of perfectly supporting and protecting the neck, waist, wrist and knee, it is favored by space scientists all over the world, and its business covers the United States, Germany, France, Britain, Italy, Canada, Denmark and Greece.
It can be seen that the purchase of space memory cotton pillow depends on whether it is pure material, whether it passes the security check, service life and brand. There are many brands of space memory cotton on the market, such as products with better performance and after-sales service, such as Dr. Sleep. It is suggested that people choose appropriately according to actual needs.
