Silkworms and Spiders Use an Environmentally-Friendly Process to Produce Fibers

Man-made fibers such as nylon and polyester are synthesized in chemical plants fuelled by oil. The actual process of synthesizing fibers also involves high temperatures and high pressures, which uses up a large amount of energy. However, silkworms and spiders produce thread very easily without using either high temperatures or pressures.

Energy saving

Researchers have begun to investigate creating nozzles imitating the fusula (tube of a silk gland) of the silkworm in order to produce fibers.

We can investigate the processes through which silkworms and spiders create threads (including the raw materials and their transformation into fibers) and apply our findings to the synthesizing of chemical fibers, using more environmentally-friendly methods to produce fibers.
