中国也缺原料
And there's now a global shortage of melt-blown fabric due to the increased demand for masks — and the difficulty in producing this material. Costing upward of 3.8 million euros ($4.23 million) apiece, the machine that creates this fabric melts down plastic material and blows it out in strands, like cotton candy, into flat sheets of melt-blown fabric for face masks and other filtration products. A similar line of machines can create a related kind of fabric, called spun-bond fabric, also used in face masks and in medical protection suits worn by health-care workers. The machines are not easy to make because of the exacting precision required, says Müller: "You need to stretch these fibers by hot air, and [the air] needs to be in perfect condition over the width of the machine. The biggest dilemma is that many of the machines are not producing consistent quality." Reicofil's Müller says he gets more than four dozen requests a day, mainly from China, to buy melt-blown fabric and production lines but has to turn nearly all of them away; making a single machine line takes at least five to six months.
不可思议，不知道CDC 干啥了
我买的3M N95 8210 工业用口罩， 也是made in USA.
我现在就奇怪了，为什么现在连工业用口罩也不够了？
还是医院没有重视不给医护人员戴？
要是不够，我把我那三四十个捐了
我也记得这个帖子。
这时候医院对口罩之类的消耗是天文数字，我记得香港医管局两个月前说过是平时消耗的五倍以上
从中国进口什么材料？如果是棉布估计没办法了，印度棉花不出口了，中国也买不到了。

三月初Pence说的是每个月35个million的量
美国储备3000万，Pence许诺月产3500万，医疗需求3亿。
Honeywell计划在罗德岛建厂。
现在建厂来得及吗？
不是说要回流嘛
