We could take dope directly from spiders.

我们可以直接从蜘蛛身上提取纺丝液。

No other creature on earth has raised the art of spinning silk to such perfection.

没有其它生物能将纺丝艺术发展得如此完美。

At the moment, those threads are created by a process called melt-spinning.

前，这些线程是通过一种叫做熔融纺丝的过程创建的。

Or, we could engineer bacteria or other organisms to make dope for us.

或者改造细菌或其他有机体来生产纺丝液。

Dr Stachewicz and Mr Ura propose instead to use a technique called electrospinning. This also involves a hollow needle.

塔切薇兹博士和尤拉先生提议使用一种叫做静电纺丝的术，这也涉及空心针。

Individual spiders — even enormous ones — can't really give us a useful amount of dope.

单个蜘蛛——即使是巨大的蜘蛛——都法正为我们提供大量的纺丝液。

As the dope travels through a duct in the spider's abdomen, the spidroins form chains and other structures.

当“纺丝液”通过蜘蛛腹部的一个导管时，蜘蛛丝蛋白形成链条等结构。

Here's how spiders do it: They store proteins called “spidroins” in a liquid crystalline solution called “dope.”

它们将“蜘蛛丝蛋白”储存在一种叫做“纺丝液”的液晶溶液中。

By electro-spinning that silky material onto a flat surface, they create a mesh material.

通过将这种丝质材料静电纺丝到一个平面上，他们创造了一种网状材料。

The truth is that we just don't know enough about the spidroin-encoding genes, or the biological process of transforming dope into silk.

事实上，我们对于蜘蛛丝蛋白的基因编码和纺丝液转化为蛛丝的生物学过程了解不多。

" It is a surprise to me to learn that the wool has to go through so much before it comes to the spinning, " Thornton said.

“当我得知羊毛在纺丝之前要经过很多工序时，我感到很惊讶，”桑顿说。

To make silk ourselves, we not only have to figure out a way to replicate the dope — we also have to figure out how to spin it.

我们如果想要自己生产出蛛丝，不仅要找出复制出纺丝液的方法，还必须弄清楚如何把它纺成丝。

One consequence of electrospinning is that the voltage attracting the thread from needle to drum also attracts or repels, according to their polarity, the charges on the molecules within.

静电纺丝的一个结果是，根据针管内部分子的极性，将线从针管吸引到滚筒的电压也会吸引或排斥其中的电荷。
