Cashmere is made by shearing the fur from goats, removing the outer goat hair from the undercoat that makes the cashmere, spinning the fibers into a yarn and knitting these fibers into a fabric. Natural cashmere fibers vary in color and may be dyed during processing to make different colored garments.
Fur from goats is collected by shearing or combing to remove the goat's undercoat in the spring when the goats are molting.
Sort the collected fur to remove the coarse outer hair, dandruff and any other material. Any remaining hairs are woven into the fabric and must then be removed by hand.
Dye the cashmere fibers to the desired color, and then arrange the fibers in a web so that all of the fibers are going in the same direction. Place strips of the web into a spinning wheel to twist the cashmere fibers into a yarn.
Feed the cashmere yarn into a knitting machine. Knitting machines can be programmed to create the desired stitches to make the necessary pieces for the garment. Once the pieces are knitted, sew the garment together, and tack the edges. This process stops the garment from unraveling.
Wash the finished garment with detergent to remove the oils and excess dye from the cashmere. After washing and drying, the cashmere should feel soft.
Acrylic fabric is primarily made from a manufactured substance called "acrylonitrile." The DuPont chemical company created acrylic in 1944, but it was not commercially available until six years later. The fabric has a smooth and soft texture.Full Answer >
Nylon is made from polyamide fiber, derived from a diamine and a dicarboxylic acid that is formed into thin strands and woven into fabric. It is a synthetic fabric that utilizes the chemical by-products of coal, petroleum and agricultural products. Synthetic polymers give nylon fabrics a low absorbency rate ideal for swimwear, stockings and athletic clothing.Full Answer >
Silk fabric is made by collecting filaments from a mulberry silk moth's cocoon, combining the output from four to eight cocoons into a single strand of raw silk, washing and preparing the silk strands and then weaving or knitting the strands into fabric. Approximately 2,500 silkworms must work to produce a pound of raw silk.Full Answer >
Filament fibers refer to fibers of long continuous lengths, while staple fibers refer to those of shorter lengths, which are about a few inches long. Most natural fibers, such as cotton and wool, are staple fibers. Synthetic fibers, such as nylon and polyester, are considered filament fibers. The natural fiber silk is also a filament fiber, but when filament fibers are cut short, they are considered staple fibers.Full Answer >
