Textiles Natural Man-made Synthetic
Fibers Basic Unit of all Textile Products- tiny hair like. All fibers have their own characteristics and properties, depending upon their source, chemical composition, and quality. No fiber is perfect. Each has some good, fair, and poor qualities that may make it suitable or unsuitable for certain uses.
Fibers con’t The basic characteristics of a fiber can be slightly altered but never totally changed. The fiber may be short, long, straight, or curly. These fiber characteristics greatly affect the appearance, and performance of the fabrics they are made into. The Characteristics you look for in children’s clothing is totally different that you would look for in evening wear for yourself. Thus an understanding of fibers, yarns, and fabrics if basic to the study of apparel.
Yarns Formed by a continuous strand of fibers usually twisted together.
Fabrics Are formed when yarns are combined. Fabrics may be constructed using a variety of different methods such as: o Weaving o Knitting o Felting
Fiber Sources Natural- Plant or Animal fiber that grows in nature. Two categories: Cellulosic Fibers (plant), and Protein Fibers (animal). Include: Cotton, Linen, Wool, Silk, Ramie, Hemp, Jute, Bamboo, Leather
Fiber Sources (con’t) Man-made- Made from a Natural material called Cellulose. The cellulose is turned into a liquid and poured through a spinneret. Includes: Acetate, Rayon, Triacetate, Lyocell. o Spinneret- Like a showerhead, that sprays out chemicals that harden into long strands called filament fibers.
Fiber Sources (con’t) Synthetic- Made from chemicals, petroleum, coal, and natural gas. All of these fibers are manufactured from different combinations of petroleum, natural gas, air and water. They are poured through a spinneret. Include: Acrylic, Polyester, Nylon, Modacrylic, Spandex, and Olefin.
Fiber Structures Staple Fibers- Short & Fuzzy- Usually between 1” and 4” long. These tiny fibers already exist in a plant or animal. The fibers just need to be cleaned up, sorted, and purified before they are used for fabrics. o Short o Look lumpy and bumpy under a microscope o Include all natural fibers, except silk
Fiber Structures (con’t) Filament Fibers- Long and smooth (like fishing line) o Include all man-made, and synthetic fibers o Include Silk Spinneret- All man-made and Synthetic fibers are poured through a Spinneret to create the fiber.
Natural Fibers- Sources Plants and animals sources that grow in nature Cellulosic- Plant fibers o Cotton o Linen (flax) o Ramie o Hemp o Bamboo o Ramie Protein- Animal fibers o Wool o Silk o Leather
–Absorbent- able to take up moisture –Porous- able to breathe, air passes through –Biodegradable- able to break down –Most wrinkle easily –Tend to be more expensive –Staple fibers which look General Characteristics of Natural Fibers
Cotton advantages Strong, durable Soft Absorbs moisture Breathes well Washes easily Dyes well
Cotton disadvantages Mildews Does not spring back into shape Wrinkles easily Burns readily Shrinks
