Study Notes
Fiber Classifications
- Four chemical classifications of fibers: cellulose, protein, mineral, synthetic.
Natural Fibers
- Cellulose fibers: Plant-derived fibers; example includes cotton.
- Protein fibers: Animal-derived fibers; example includes wool.
- Mineral fibers: Sourced from minerals; example includes glass.
Synthetic Fibers
- Created through chemical processes; example includes nylon.
Cotton Characteristics
- Cotton is hydrophilic, meaning it absorbs water and becomes 30% stronger when wet.
- Main advantages of cotton fiber are absorbency, breathability, and a soft feel.
- Considered the "fabric of our lives" for over 7,000 years, highlighting its historical significance.
- Cotton fibers are classified as staple fibers, meaning they are relatively short.
- Approximately 31% of the world's fiber consumption consists of cotton.
Cotton Production
- Major cotton-producing countries include India, China, and the United States.
- Cotton fibers originate from the boll or seed of the cotton plant.
Quality of Cotton
- The highest grade of cotton is white cotton, known for its purity.
- "Cleanliness" in cotton refers to the amount of leaves and stems left in the fiber, affecting its quality.
- Examples of high-quality cottons with longer staple fibers include Sea Island, Pima, Egyptian, and Supima.
- Higher quality cottons such as Sea Island and Pima are silkier, stronger, and more lustrous compared to regular Upland or Alcala cotton.
Special Types of Cotton
- Colorgrown cotton: Naturally grown in various colors, eliminating the need for dyeing.
- Organic cotton: Cultivated with minimal environmental impact, avoiding toxic fertilizers and pesticides.
Bast Fibers
- Definition pending to elaborate on plant fibers obtained from specific plants.
