How To Find A Good Memory Cotton Manufacturer
- Apr 10, 2018 -

Polyurethane memory pillows have frequently appeared in people's field of vision in recent years. Indeed, in Western developed countries, mattresses made of memory cotton, pillows, and various leisure pillows, car pillows have gradually replaced traditional products and started to enter every household.

    With such a large market for memory pillows, is it really like the benefits of 1, 2, 3, 4, 5, etc. that some companies say? To understand this problem, we must start with the origin of memory cotton.

    Memory cotton is an open-cell polyurethane polymer with special viscoelastic properties, very soft material properties, and strong impact energy absorption. This kind of material molecule is very sensitive to temperature, so it is also called warm memory sponge. This material first appeared and was applied to a NASA study: Apollo Command Cabin Life Saving System Design. This material was developed to be used on the seat of a spacecraft to absorb rockets (spacecraft). ) Great impact on astronauts caused by take-off, return of the spacecraft to the atmosphere, accidents (falling), and improvement of the protection and comfort of the seat to astronauts. Because the memory cotton was originally born in the United States Space Agency, it is often used as a space memory cotton, meaning that it originated from the technology of the US Space Agency.

    From a popular point of view, memory foam was first used primarily as a cushioning material. Since this is the case, the car waist pillows, car waist pads, car headrests and other products made of memory cotton surely have a certain release effect on the reactionary forces brought by the seat belts at a crucial moment.

What are the temperature and viscoelastic properties?

    The temperature-sensing characteristic refers to the fact that it senses the temperature of a human body and gradually becomes softer. At the same time, it absorbs human body pressure and adjusts the human body to the most comfortable posture state. For the part that has not reached the human temperature below, it still maintains sufficient support;

    Viscoelastic properties mean that the product is under pressure and sag, but it does not show a strong rebound force (such as clay pressure sags); when the pressure is removed, the product will gradually return to its original shape (such as spring recovery).

    From this, we can know that polyurethane memory foam is a material that has plasticity and provides more support. Based on these two points, it can be used as a material for pillows. And its viscoelastic properties can be used as a pillow core completely fit the neck muscles, increase the cervical area, so that the cervical vertebrae completely fit the pillow, changing the traditional pillow at both ends of the force, the middle of the suspended state. The second temperature-sensing feature is the overall softer and more comfortable place where the neck skin touches. It seems that memory foam pillows are also scientifically based.

    With the liberation of the sleep cervical spine at night, the protection of the neck muscles and cervical spine is also highlighted. The benefits of the memory pillow to the cervical spine are self-evident. So isn't every memory pillow has the same effect on the cervical spine?

From this point of view, what memory cotton manufacturers say is not entirely unreasonable.

     However, the memory pillow manufacturers on the market are mixed, so how can we choose a good memory pillow manufacturer?

     Smell: Good memory foam is odorless. Some so-called memory foam on the market has a very pungent number. As a product that comes into close contact with the skin, the pungent odor tends to add more chemical ingredients.

     Pinch: A good memory foam springback time is 3-5 seconds, too fast there is no viscoelastic properties of memory cotton, too slow will not achieve the effect.

     Said: memory cotton has the density of the points, the greater the density, the heavier the unit weight, the density of memory cotton unit D, generally 50D to 90D products. If you exceed this number, you must be careful.
