Wood pulp cotton rag manufacturers talk about the types of sponges used in industrial production
There are many types of sponges used in industrial production, including foamed cotton, memory cotton, shaped cotton, rubber cotton and other sponge products.
Recycled cotton
Recycled cotton is made from waste cotton, industrial scraps, and the fabric and yarn ends of textile enterprises. In particular, the raw materials may also contain waste cotton for medical use. Therefore, recycled cotton will cause harm to human health. Cotton and civilian cotton placed together can easily cause pollution. Good quality cotton wool is generally soft in color, white or milky white. The fibers are fluffy and uniform, and the hand feels soft and elastic. Recycled cotton from old cotton has an odor due to sulfur bleaching or washing with washing powder, while recycled cotton produced from clothing waste will have odors such as medicinal and musty odors. Regenerated cotton itself can be produced, but it can only be used for industrial and agricultural insulation such as greenhouses and greenhouses, and cannot be used in the daily life of ordinary people. If it is used for industrial and agricultural insulation, the black and white spots of recycled cotton do not matter at all. Recycled cotton is processed from fibrous industrial scraps. It is harmful to the human body due to chemical bleaching and dyeing and other processes. Therefore, the state does not allow it to be used in common people's cotton coats or quilts or places that directly touch the human body.

foam cotton
This material is foamed with polyether, like foamed bread. It can be foamed by mechanical equipment or artificially surrounded by wooden boards. The foamed cotton is like a square loaf. Use a slicing machine to go through the slicing process, and cut the thickness according to different requirements. The hardness of the foamed cotton can also be adjusted. . The seat cotton generally uses 25~28kg/m3, and the other uses 20~22kg/m3 density. Although the softness and hardness of sponges are directly related to density, they are also related to different additive formulations. Therefore, the industry is divided into high elasticity, gray super, black gray super, and soft cotton. When designing and using products, reasonable and scientific matching should be carried out according to different shapes and structures. Generally, sponges with different elasticity and density are divided into three parts: upper, middle and lower. There is a kind of fire-resistant cotton material (flame retardant cotton) in the sponge. In fact, before the sponge is foamed, a fire-retardant agent, such as chlorine and bromine, is added to the material formula to make the sponge produce fire-fighting smoke when it catches fire.
rubber cotton
It is a kind of sponge. It is made of natural latex as the main material. It has rubber properties, good elasticity, good resilience and no deformation, but it is expensive, 3 to 4 times higher than foam cotton.
Styling cotton
This material cotton is made of polyamide material, mixed with various additives such as foaming agent, and the pressing agent is put into a simple mold and heated to extrude sponges of different shapes. It is suitable for swivel sofa seat cushion, back cotton, and a small amount of armrests Made of shaped cotton. At present, the material density is 55#~60#, and its elasticity is more in line with the relevant national standards. The elasticity and hardness of the sponge can be adjusted, and it can be adjusted according to different parts of the product. Generally, seat cotton is higher in hardness and density, followed by back cotton and softer cotton.
