Pearl cotton, the scientific name of granular cotton, is made of hollow polyester staple fiber and processed by special granulation technology. It is the latest popular special filler for pillow cores and cushions abroad in the late 1990s. When mixed with down, it can not only keep down warm, but also increase the elasticity of down products, such as down bedding, pillow core and cushion. Pearl cotton is named for its appearance. In fact, like hollow cotton, they are all chemical fibers.

Pearl cotton is a good pillow core, because it has the characteristics of soft touch, light weight and strong elastic recovery. Mainly used as pillow core and headrest. But the price is more expensive. Advantages of pearl cotton compared with fiber cotton: Compared with the traditional pillow core filled with fiber, the pillow core made of pearl cotton has the following advantages: the pillow core and down bedding have the effect of micro massage. Because pearl cotton is granular and highly elastic cotton, they are relatively free spheres in the pillow core. After being pressed, in addition to the deformation of the sphere, they will make relatively small movements according to different sleeping positions of the human body, thus producing a micro-massage effect, which will be enhanced especially when breathing after sleeping. And because pearl cotton is spherical, the surface of the pillow core will be soft and concave. With the high elasticity and super resilience of pearl cotton, when you rest on the pillow, the elasticity is better than that of the traditional pillow core. Because pearl cotton is spherical, it is not easy to be squashed and has good resilience. Compared with ordinary fiber cotton, its shape can better decompose the pressure, support the neck and better maintain the shape of the pillow!
