暑假里我帮妈妈拆毛衣,听妈妈说:“毛线用热水烫一次就掉一次色,用温水洗不掉色,但毛线洗不直。”恰在这时,火炉上的水开了,我拿着拆下的毛线去拎水,无意中把毛线挨着了正喷蒸汽的壶嘴,突然发现毛线变直了。我想,要是能在水壶上安个管子,让毛线从管中一过,蒸汽就喷在毛线上,毛线不就直了吗?毛线拉直后再用温水洗又不褪色,两全期美。 In the summer vacation, I helped my mother to remove the sweater and listen to my mother: “The wool is washed once with hot water and it is washed out once. It does not fade with warm water, but the wool is not washed straight.” Just at this moment, the water on the stove opened. , I took the removed wool to dip the water, inadvertently carried the wool to the mouth of the spouting steam, suddenly found the yarn straightened. I think if we could put a pipe on the kettle and let the wool pass through the tube, the steam would be sprayed on the wool and the yarn would not be straightened. The yarn would be straightened and then washed in warm water without fading. .
