基本上来说，把包含两根金属丝的纤维连接在一根弹簧上。
Basically, you use fibers that contain two metals bonded together in a tiny spring.
当温度下降的时候，其中一根金属丝的长度发生改变——引起纤维蜷缩。
As the temperature drops, one metal changes its length more than the other one - resulting in a "curl" in the fiber.

Used for testing breaking tenacity, elongation at break of single yarn made of cotton, wool, jute, core-spun yarn etc, at the same time including synthetic fibre filament, textured yarns.
借助镊子，研究人员随后用芳纶纤维包裹了每根塑料丝。
Using tweezers, the researchers then wrapped each of the plastic wires with a Kevlar fiber.
用于测定棉、毛、麻、包芯纱的单根纱线及合成纤维长丝，变形丝的断裂强力和断裂伸长率。
