Throw your laundry into the dryer1 without a dryer sheet, and it comes out a rumpled2, “staticy” mess.
不加干衣机用纸就把衣物一股脑扔进烘干机里,结果衣物肯定是皱巴巴,而且还带静电。
Toss one in and the results are much better.
而只要放入一片就会截然不同。
How can adding this flimsy sheet change the way all your clothes come out of the dryer?
这纤薄的一张纸究竟对烘干机内你的衣物施加了何种魔法?
When you first add a dryer sheet to your wet laundry, it does nothing at all.
当你第一次将干衣机用纸放到湿衣服里,一点用也没有。
It only starts working when the dryer is on.
只有在你打开烘干机时才开始起效。
The warm air that circulates through the damp clothing releases chemicals from the dryer sheet, and these chemicals permeate3 all the clothing, even clothing the dryer sheet never directly touches.
干燥机的热空气在湿衣物周围循环释放干衣机用纸的化学物质,而就是这些化学物质渗透所有进衣物,甚至用纸都不直接接触。
The chemical that a dryer sheet releases is known as a “surfactant.”
用纸上的化学物质被称为“表面活性剂”。
Most surfactant molecules4 have two sides:
大多数表面活性剂分子都有两个方面:
one that holds onto water, and one that holds onto fats and oils.
一个是保持水分,另一个则是保持脂肪和油。
