【英语时差8,16】衣服为什么会缩水？（上）

If your hair drier shrunk your head to the size of a grapefruit, you’d be astounded¹. If your wool pants shrank in the drier, you’d be angry but not amazed.How can clothing disobey the laws of common sense, and shrink in the laundry? To understand why this happens, we need to take a closer look at the microscopic² structure of natural fibers³ like wool. Each thready strand⁴ you can see is composed of millions of long, tangled⁵ molecules⁶ called “polymer chains.” Microscopically⁷, these start out coiled like miniature, tangled springs, something like a mass of tangled telephone cords.These curly molecules are stretched and straightened as the wool is carded and spun⁸.
