Cotton Jeans; Nothing else comes close.
Turning Cotton Into Jeans

Cotton is a plant that starts out as a seed and is grown and then it is harvested into large bales. It is the taken to a textile mill that then separates the lint where it gets mixed and cleaned it is then sent to a device known as a carding machine. This machine uses a combing action to clean and straighten the fibers and turns the lint into a soft untwisted string called a sliver (pronounced sly-ver).

A spinning device then takes the sliver and twists it into a continuous fiber that is then wrapped around a spool. This is now yarn that is suitable for weaving or knitting into fabrics.

This cotton yarn is then taken to a machine called a loom. Modern looms weave cotton yarn into fabrics the much the same way the first hand weaving frames did. In fact in many non-industrial countries these frames still make fabric today. However modern mechanized looms work at great speeds.

The yarn that runs the length of the fabric is known as the warp and the crosswise yarn is known as the filling. It is this warp and filling that gives jeans their distinctive course pattern.

This raw jean material is then sent to a finishing plant where it is bleached, pre-shrunk, dyed, or given a special finish before being made into blue jeans.
