Document Summary

Textiles final exam notes: nonwoven: fabrics made directly from fibers without processing the fibers into yarns. Production: made from a variety of fiber types through a variety of processes. Production rates are very fast and the fabrics are inexpensive. Uses: extensive use in medical textiles and interlining to stiffen certain areas of garments like collars and shirt cuffs. Problems: limited in apparel because the fabrics tend to have very poor draping ability: films: Vinyl: wash, stiffen when dry-cleaned, stiffens in cold weather. Polyurethane: washable and dry-cleanable, soft in cold weather. Plain film: dense, uniform, firm: impermeable to air, water, soil and stain resistance, recovers well from deformation. Expanded: spongier, softer, tiny air cells in film, not as strong or abrasion resistant as plain film: web stabilization: used to make nonwovens and is done by: Heat and pressure: thermoplastic fibers are required: spun-bonding and melt-blowing is a continuous process starting from the polymer to the non-woven fabric.
