Document Summary
Properties of cellulosic fibers: hydrophilic- good absorbency. Dye well: careful storage required to prevent mildew, inflammable- burn steadily in flame and out of flame, good thermal conductors- easily transfer heat through fabric. Help body release heat: electrical conductor- no static buildup, low resiliency- wrinkles badly unless finished for wrinkle recovery, cellulosic fiber: plant part. Assess quality by: staple length grade character, twist in fiber, longer length = better quality, natural texture enables fibers to cling together, best grade= lustrous silky white clean, best character=mature smooth uniform w/in bale strong has convulsions. Hemp: coarser and stiffer than flax: longer fibers form outer region of stalk, strong, useful for twine, cordage, thread, environmentally friendly, commercial production illegal in us. Ramie: requires a hot humid climate: fast growing, stiff brittle, stronger when wet, dry cleaning preserves color, blends well with other fibers, common in the us. Cellulosic fiber- from veins or ribs of a leaf: sisal, pineapple (pina)
