Everyone knows that if you look at a set of sofas, besides looking at its color and workmanship, the main thing is its raw materials. So the sofa sponge is an important raw material for the sofa. The quality of the sofa can completely determine the quality of the sofa. . Why do you say this way? When we use the sofa for a period of time, we can find that for those sofas with poor quality, the sofa will be recessed, and it is obvious that relatively good sofas, although it is a bit concave, will not be obvious. So when we buy a sofa, we should know a bit about the sofa sponge. Here we introduce the common sofa sponge:
1. Zhenzhumian Zhenzhumian is specially processed by high-pressure process. It is the smallest molecule among all sponges with the highest elastic resilience. EPE is compressed and its texture is tightly arranged in a bead shape. With the process of use, its Pearl particles will gradually release the internal stress, with more and more fluffy characteristics, so the use of EPE processing pockets shape fullness is particularly good, and the resilience is very tough. However, the cost of pearl cotton is relatively expensive, so it is generally used only with small pillows and lumbar pillows that have the highest frequency of use and the most destructive force.
2, Penguin Cotton (The longer the sprayed cotton fiber, the better the quality) All large pillows, cushions of 35 density
The sea surface is covered with a layer of spray cotton. The use of sprayed cotton can reduce the friction of the fabric and the sponge, increase the smoothness of the sitting sensation, and make the lines of the sofa look particularly soft and vivid.
3, the shape of the cotton Special shape of the sponge, a good manufacturer is the use of a whole piece of stereotypes sponge foaming completed. In order to save the cost, many manufacturers use the sponge material to bond into a whole piece and cut it into pieces. The service life and flexibility of the sponge are greatly reduced.
4, doll cotton because the pillow sponge needs texture is particularly soft and comfortable, while the spine has a very good supporting role, it is recommended to use a density of 30A 3A filament special type doll cotton, this sponge texture is close to the natural Just popped out of cotton, but more flexible and resilient, pure cotton, environmental protection and no odor.
The process of the sponge determines the density of the sponge. The current density of the domestic sponge can reach but does not exceed 35%. And more than 35% of them are gum products. Because the cost of the resin products is quite expensive, some unscrupulous merchants artificially add talcum powder in the production process to increase the density in order to achieve a high density of sponges, but the fossil powder processing process The use of a large amount of ingredients containing formaldehyde, toluene, etc. that are fatal to the human body, and the addition of fossil powder, it is easy to fall off. At the same time, the life and performance of the sponge are seriously impaired. Sit on, sofa stiff without any flexibility.
