FABRICS Disadvantages of cotton fiber are considered immaterial

Cotton absorbs moisture and feels cool and comfortable.
KNIGHT RIDDER NEWSPAPERS
Cotton is the most widely used fiber in the textile world. In the heat of summer, it's especially popular because it absorbs moisture and it feels cool and comfortable.
The history of cotton goes back thousands of years, but it was Eli Whitney's invention of the cotton gin in 1793 that changed its production. His machine separated the fiber from the boll, and new factories sprang up to spin, weave and dye the cotton. Although it's grown in hot climates around the world, the United States and China are the top producers today.
Cotton takes dye very well and is probably nature's most practical and affordable fiber, but it does have some drawbacks:
UIt launders well but is subject to shrinkage, so pre-shrinking is recommended for many types.
UIt's not very resilient, so it can wrinkle.
UIt doesn't have suppleness for drapability. Use an appropriate pattern.
UIt can turn yellow when exposed to sunlight for a long time.
To counteract some of the disadvantages, the fabric is commonly treated with special finishes. You may see a descriptive phrase on the end of a bolt, such as "water repellent," "shrink resistant," "durable press" and more. These finishes change the characteristics of the fiber and make them more practical.
Wide variety
There are over 40 different kinds of cottons, from lightweight sheer voile or batiste, to heavy denim or velveteen. Familiar varieties include broadcloth, batik, canvas, chenille, corduroy, damask, gauze, jersey knit, organdy, oxford cloth, percale, poplin, pique, terry cloth and twill. Many are popular year round, not just in summer.
When shopping for cotton yardage, look for better qualities, those with a tighter weave and straight grain (lengthwise and crosswise threads intersect at straight angles). Prints should be clear, and plaids should be straight. Watch for one-way designs, nap or luster that might require a one-way layout in cutting. Most cottons are easy to sew.
