Turning A Problem Around: The Whitney Cotton Gin

If you went to elementary school in the United States, you no doubt learned about Eli Whitney’s cotton gin as an example of how the industrial revolution took previously manual processes and replaced the low-efficiency of human labor with machines. The development of the cotton gin — patented in 1794 — involves an interesting lesson about solving engineering problems.

Farmers in the southern United States had a big problem. Tobacco was a cash crop, but it eventually left your fields barren and how to solve that problem wasn’t understood yet. Indigo was valuable for dye, but the British were eating away that market with indigo created in its colonies. Rice requires a lot of water and swamp, so it was only suitable for certain areas.

There was one thing that grew very readily in much of the land: cotton. Unfortunately, the cotton had little seeds you had to remove. A single person could clean — maybe — a pound of cotton a day. In the late 1700s, plantation owner Catharine Littlefield Greene introduced Whitney to a group of farmers were trying to decide if there was a way to make cotton a more profitable crop.

Filling The Automation Gap In Garment Manufacturing

Even in this age of wearable technology, the actual fabric in our t-shirts and clothes may still be the most high-tech product we wear. From the genetically engineered cotton seed, though an autonomous machine world, this product is manufactured in one of the world’s largest automation bubbles. Self-driving cotton pickers harvest and preprocess the cotton. More machines blend the raw material, comb it, twist and spin it into yarn, and finally, a weaving machine outputs sheets of spotless cotton jersey. The degree of automation could not be higher.¬†Except for the laboratories, where seeds, cotton fibers, and yarns are tested to meet tight specifications, woven fabrics originate from a mostly human-free zone that is governed by technology and economics.
