Sponge manufacturer Zhen Yue takes you to understand what are the main properties of packaging sponge:
Regenerated cotton is purchased from waste cotton flowers, leftover materials from industrial production and rags and cotton yarn heads from textile industry, and then used to make it. Especially in the raw materials, it is very likely to contain waste cotton for diagnosis and treatment. Therefore, regenerated cotton will cause adverse effects on health. The mutual placement of regenerated cotton and civilian cotton is very easy to cause environmental pollution. Cost-effective cotton wool is generally mild in color, white or milky white. Chemical fiber bulky and well-proportioned, soft touch and good ductility. Old cotton floss regenerated floss has peculiar smell because it is cleaned with sulfur powder, bleach or soap powder, while regenerated floss produced from fabric waste will have peculiar smell such as medicine smell and peculiar smell.
When designing products for application, effective scientific research and matching should be carried out according to different modeling design and structure. Generally, sponge with different ductility and relative density should be matched in three positions: upper, middle and lower. There is a kind of raw material called fire safety cotton (flame retardant cotton) in sponge. In fact, before sponge polyurethane is foamed, fire retardant is added to the secret recipe of raw materials, such as chlorine and bromine, which will cause fire extinguishing smoke when sponge catches fire and has flame retardant effect.
③ Rubber packaging sponge
One kind of sponge, it uses the main material is natural latex mattress raw material polyurethane foam, it has the characteristics of rubber, good elasticity, good resilience, not easy to deformation, but the price is expensive, higher than the foam 3~4 times.
④ Packing sponge
This raw material cotton is made of polyamic acid raw material, mixed with various preservatives such as foaming glue, and pressed into a simple grinding tool to heat up the sponge, which is suitable for swivel chair fabric sofa cushion, back cotton, and a small amount of guardrail is also made of 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.
