There are two kinds of sponges, one is natural sponge and one is synthetic polyester cotton. I'll give you a detailed introduction below!
Sponge is a porous material with good water absorption and can be used to clean items. People commonly use sponges made of lignocellulosic fibers or foam polymers. There are also natural sponges made of sponge, mostly used for body cleaning or painting. There are also synthetic sponges made of three other materials, namely low-density polyether (non-absorbent sponge), polyvinyl alcohol (super-absorbent material with no visible pores), and polyester.
Natural sponge is a simple multicellular marine animal. Natural sponge is a simple multicellular marine animal, one of the first multicellular organisms on earth. Natural sponges are very sensitive to their environment. They only grow in warm, moderately saline, mild, pure waters with ocean currents. Sponges are attached to rocks on the seafloor at depths of 20 meters to more than 200 meters. Most quality sponges grow on the seafloor at depths of 20 to 50 meters. The size of sponges generally varies from a few centimeters to one meter. Depending on the sea area, the growth period of sponges with a diameter of about 15 cm takes 2-4 years.
Currently, sponges are mainly distributed in the Mediterranean Sea, the Gulf of Mexico and the Bahamas. The main species are honeycomb cotton, silk cotton, grass cotton, elephant ear cotton and so on. The natural sponge produced in the Mediterranean Sea is also the world's high-quality sponge.
