Cotton is a soft fiber that grows around the seeds of the cotton plant. Cool, soft and comfortable, cotton is presently the world's most used fiber. Every part of the cotton plant is useful and we see its application in industries such as apparel, home furnishings, medical and surgical, automobile, etc. Cotton fabrics have a pleasant matte luster, a soft drape and a smooth hand. They are very comfortable to wear due to their soft hand and other characteristics. Cotton fabrics have excellent absorbing capabilities. Cotton garments absorb perspiration, thus keeping the person more comfortable. "Absorbent" cotton will retain 24-27 times its own weight in water and is stronger when wet than dry. This fiber absorbs and releases perspiration quickly, thus allowing the fabric to "breathe". Cotton products can typically be machine washed and dried. Colored cotton garments retain their color longer if they are washed in warm or cool water.
Acrylic fiber is a synthetic fiber that closely resembles wool in its character. According to the definition of the ISO (International Standards Organization) and BISFA (International Synthetic Fiber Standardization Office), fibers which contain a minimum of 85% acrylonitrile in their chemical structure are called "Acrylic Fibers".
Acrylic fiber is composed of acrylonitrile and a comonomer. The comonomer is added to improve dyeability and the textile processability of the acrylic fiber. Acrylic fiber can be used 100% alone, or in blends with other natural and synthetic fibers.
