In modern times, our clothes seem good enough to meet our needs both in color and style. However, are you impatient with washing your clothes so often? Are you tired of the same color? If your answer is “Yes”, let’s meet the fashion in the future.
Sun-No-Spot
To clean this shirt, just stand in the sun! A special material on the surface receives UV light from the sun. This heats it up enough to make stains(污渍) missing. You stay cool, but stains disappear! Some stains disappear in minutes — others might take a day.
New Fabric Suit
Are you sick of holes in your clothes? This new material repairs itself! If this cloth gets a hole, just rub(搓揉) the broken place quickly. Heat from the rubbing will cause the materials to connect with each other again, repairing the hole. Hole? What hole?
New Wiggle Vigor
This cloth gets a charge(充电) from running around. As you move, the thin wires in the material turn your movement into power. This can charge a computer, an ipad, a hair-dryer, and many other small things that need power.
Chameleon Cloth
Tired of the same old look? How about clothes that change colors? This material is made with dyes(染料) that change colors when they get warm. A small battery heats up thin metal threads(金属线) in the cloth, to change colors or forms.

y = sin x， x∈R， y∈[–1，1]，周期为2π，函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x， x∈[–1，1]， y∈[–π/2，π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
