Check your shirt or pant tag and cotton will likely be a factor in your clothing content. Cotton fibers are used in twill, seersucker, corduroy, cambric, denim, terrycloth, and blended with rayon, polyester, and other synthetic fibers. You can find cotton in coffee filters, paper, nitrocellulose (it explodes!), livestock feed, and vegetable oil. Spanish missionaries were the first to grow cotton in Texas, and the first recorded production, thousands of pounds that year, dates to 1745. Barbed wire fencing and the removal of Native American populations stimulated an increase in cotton growing, but it was a change in plow design, making it easier to break apart the prairie soil, that gave cotton growing in the state a real boost. Since then, Texas has grown and processed cotton across the state, from the Rio Grande Valley to the High Plains, where the flat landscape breaks with silver towers of cotton ginneries. Today, the United States is one among the world's top 10 exporters of cotton, and Texas leads the country, contributing to the 18 million bales of cotton shipped overall.
