Recently, in -orbit Chinese astronauts living in the Tiangong space station posted a video online of the crew unpacking their supplies sent by a cargo craft. These space packages are made of a special innovative material.

　　In the cramped space of the space station, if the items are packed in plastic bags or paper bags, astronauts may inhale the gas with chemical volatile agents released by the bags, which will be harmful to their health.

　　In order to meet the special needs of the space station, a Chinese research team took five years to extract fibers from crab shells as the main material, and attached them with other functional fibers, successfully developing this new type of fabric.

　　Not only is it anti -bacterial, anti-mildew and anti-static, the fabric is also a highly efficient flame retardant. Even if burning under certain conditions, it will not generate harmful gases.

　　Additionally, the gas released by this fabric is far less than one microgram per gram, which is very small and can ensure the health of astronauts.

　　At present, this crab shell fabric has been widely used in Chinese space station cabins. The airlocks, cabin interiors, space packages, and astronaut storage bags are all made of it, and to date there has been no mold and bacteria growth on the surface of the interior film of the current in-orbit Chinese space station.
