Each cotton fiber, no matter how large it grows, is made of just one cell.

不论长成多大个，每根棉纤维。

It seemed to have been made of cotton fibers, and was covered with the softest bits of leaf and bark.

它看上去就像是用棉线编织成的，上面覆盖着柔软的叶子和树皮。

Cotton fibers are treated with many types of chemicals, she notes.

她指出， 棉纤维经过多种化学处理。

These seemingly contradictory features — strength and flexibility, softness, and durability — have their roots in the intricate biology of the nearly invisible cotton fiber.

这些看似相互矛盾的特性——强硬度和灵活性、柔软度和耐用性，来源于复杂生物学中肉眼几乎无法看见的棉纤维。

The next crucial stage of the cotton fiber's growth begins as it thickens its secondary cell wall by depositing large quantities of cellulose into the secondary layer.

在下一个棉花纤维成长的关键阶段，大量纤维素在次生细胞壁内堆积并从而强化细胞壁。

Then the cotton fiber's spun into yarn, the yarn is then dyed to a specific color and then that yarn is then woven into denim.

然后将棉纤维纺成纱线，然后将纱线染成特定颜色，然后将纱线织成牛仔布。

The same goes for our pets: their dander and hairs enter the mix, as do tiny pieces of thread and cotton fibers from our clothes.

我们的宠物也是如此：它们的皮屑和毛发混入其中，我们衣服上的细线和棉纤维也是如此。

The device is made up of hundreds of cotton fibers  which are impregnated with graphite, wrapped into a cylinder about the thickness of a soda straw.

该装置由数百根浸有石墨的棉纤维组成，包裹成一个大约苏打吸管粗细的圆柱体。

Working with them, we created one of the best yarns in the world, which consists of thin metallic alloys wrapped around with polyester fibers and cotton fibers.

与他们合作， 我们创造了世界上最好的纱线之一，它由用聚酯纤维和棉纤维包裹的薄金属合金组成。

In ideal growing conditions — with the right temperature, water, fertilizer, pest control, and light — a cotton fiber can grow up to 3.6 centimeters long with only a 25-micrometer width.

适宜的温度、水、肥料、害虫防治，还有光线。这样，一根棉纤维可以生长至长 3.6 厘米，宽仅为 25 微米。
