NPR JUST IN: President Trump says the CDC is recommending that Americans consider wearing cloth masks to help prevent the spread of the coronavirus, along with social distancing and handwashing recommendations. “This is voluntary. I don’t think I’m going to be doing it,” he said.
想起一周前就有人发推说10天内CDC会改变关于口罩的建议
反射弧真TMD长。
哈哈哈哈
划时代的重大发现？
要180Thread count以上才好，Tshirt不行好像。 https://www.google.com/amp/s/www.nbcnews.com/news/amp/ncna1175966 Cotton T-shirts, however, may not be as useful. A 2013 study published in the journal Disaster Medicine and Public Health Preparedness compared medical grade surgical masks with homemade facial coverings using plain cotton T-shirts. The surgical masks were found to be three times more effective in blocking small particles than the T-shirts.
美国得现有足够的口罩供民众使用。市场上买不到口罩，黑人暴动抢亚裔的口罩你怕不怕？
这个倔老头要能自觉自愿戴上口罩就不姓川普了!
刚用T-shirts,做了一个，看见这个，又拆了条质量还不错的棉布旧衣服再做一个，不知道是不是180Thread count，反正就这样了
很多厚床单的thread count 很高。400,600,甚至1000的都有。
