Therefore, clothing is gradually evolving from one means for protecting the body to a device with various functions. For example, mountain climbing clothes, safety clothing for special workers, combat clothing for soldiers, training clothes for sporting activities, and winter clothes to cope with cold weather, The production of apparel with these specific functions is on the rise.

On the other hand, the environmental pollution problem and the energy exhaustion problem caused by the use of fossil fuels worldwide have been seriously raised, and research on alternative energy is being actively carried out. Wind energy, hydro energy, solar energy, and bio energy are attracting attention as alternative energy sources. Alternative energies have the advantage of being clean and free from depletion and pollution-free regeneration. On the other hand, the energy density is so low that it is not practicable where it needs a lot of energy, and solar and wind are affected by the climate, so auxiliary power generation facilities are needed and other alternative energy sources are less efficient and economical. Have. Therefore, countries around the world are working on the development of alternative energy that can replace fossil fuels and nuclear power, and that can be used in large quantities over a long period of time without harming the environment and human health.
