Sponge manufacturers analyze the performance of packaging sponge products into what:
Recycled cotton is made from discarded cotton flowers, industrial production waste, and textile cloth and cotton yarn heads. They are made by sponge packaging manufacturers, especially the raw materials will also have waste cotton for diagnosis and treatment. Therefore, recycled cotton will have adverse health effects. Placing recycled cotton and civilian cotton is easy to cause environmental pollution. Cost-effective lint is usually mild in color, snow-white or Milky White. Chemical fiber bulky, well-proportioned, soft to the touch, good ductility.
When designing products and applications, effective scientific research must be carried out according to different shapes, designs and structures. Usually, it is divided into three positions: upper, middle and lower to match the different extensibility and relative density of the sponge. There is a kind of raw material in the sponge called fire resistant safety sponge (flame retardant sponge). In fact, before the foam polyurethane foam, fire retardants are added to the secret formula of raw materials, such as chlorine and bromine, which can cause fire suppression when the sponge packaging product catches fire., With flame retardant effect.
③ vulcanized rubber packing sponge
One of the sponge packaging products. It is polyurethane foam made from natural latex mattress raw material. It has the characteristics of vulcanized rubber, good elasticity, good resilience, and not easy to deform. But the price is expensive, 3 to 4 times higher than foam cotton.
④ Special-shaped packing sponge
The raw material is made of polyamino acids and mixed with various preservatives (e. g. polystyrene foam). Sponge packaging product manufacturers press reagents into simple grinding tools and can be pressed into other shapes. Sponge packaging products, it is suitable for sofa cushions of swivel chair fabrics, back cushions and a small amount of guardrails, and is also made of special-shaped cotton.

How to identify natural sponge and artificial sponge?
Compared with artificial sponges, natural sponges do not have static electricity that hurts the human body, do not peel off and last long. The sponge that lives in the sea is the real sponge, and the artificial "sponge" just imitates the structure of the natural sponge. Natural sponges that live in seawater are mostly grayish yellow, brown or black lumps. Its body surface has many bulges, there are many small holes beside the bulge, and there is a large hole at the top of the bulge. Seawater flows in from small holes and out from large holes, and those tiny creatures enter the sponge with the water and become "self-contained" food. Therefore, although the sponge is called "the flowers and fruits of the sea", it looks like a plant, but it is actually an animal.
Buy a pack of large salt or coarse salt, put the coarse salt and dirty plush toys into a larger plastic bag, and then fasten the mouth of the bag tightly and shake it vigorously. You will surely find that the plush toys are clean. The crude salt removed became gray-black due to the adsorption of dirt. The principle is the use of salt that is sodium chloride adsorption of dirt. Soda powder can also be used instead of coarse salt, the same usage. This method is more suitable for large plush toys and plush toys that can not be washed with sound.
The main ingredient of the sponge?
Polyurethane soft foam rubber, polyurethane is one of the most common polymer materials in life, widely used in the production of various "sponge" products. Now there are three kinds of sponges on the market, 1: polyurethane type, burning to generate a large number of cyano-containing gases, these gases are very toxic and suffocating. 2: polyethylene type, combustion of carbon-containing gas, this kind of gas toxicity. 3: polystyrene type, this kind of foam burning decomposition of a small amount of styrene monomer, toxic, but not as toxic as polyurethane.
