PP（聚丙烯）原本是一种及其顽固的原料，要将它变成纤维本是一件不大可能的事情。指到1993年，诺贝尔化学奖得主，意大利著名化学家米里奥.纳塔经过几十次的试验，终于通过一个方程式把顽固不化的聚丙烯瓶子变成与天然羊毛一样松软的毛线，且特别容易染色，染色后有一种亮晶晶的奇异效果，艳丽可人。织出的塑料毛衣又好洗又干得快，不用熨烫，毛衣表面也不会起讨厌的小毛球，结实耐磨损，能穿好多年，拆了还可以重织。废旧塑料加工后还可以制成环保运动服，环保晴雨两用衣等，既透气又能绝缘防雨。
【正确答案】：PP is originally such a stable raw material that it is almost unlikely to turn it into fibers. It was not until 1993 that the famous Italian chemist Milleo Nata, after dozens of experiments, finally turned the “stubborn” polypropylene bottles into knitting wool that is as soft as the natural one. (Milleo Nata is a winner of the Nobel Prize for Chemistry. He achieved this by means of a chemical equation.) This kind of knitting wool dyes well and has a wonderful glistening effect. The plastic sweater knitted with such wool washes and dries easily, with no need of ironing and with no worrying of the annoying pills on its surface. And, what’s more, these durable sweaters can be unraveled and re-knitted. Wasted plastic bottles thus processed can be make into environment-friendly sportswear and all-weather clothes that are permeable as well as insulating and waterproof.
