1, law of feel range estimation: This law applies to the spin raw material that assumes position of staple in bulk.
(Fiber of 1) , cotton compares ramie fiber and other hemp kind craft fiber, wool fibre all short and fine, often mix with all sorts of impurity defect.
(Feel of fiber of 2) , hemp is rougher hard.
(Fiber of 3) , abb is curly and rich flexibility.
(4) , silk is filament, long and fine, have special burnish.
(Glue fibrous is stuck only in 5) , chemical fiber dry, wet condition is puissant difference is big.
(Silk of black silk ribbon of 6) , ammonia has very big flexibility, the length that issues it in room temperature can drawing comes fivefold above.
2, microscope watchs a way: It is according to fibrous feature of vertical face, sectional configuration identifies fiber.

(6) , common stick fine: Cross section configuration: Zigzag, leather core structure; Vertical range pattern: Fore-and-aft have groove.
(7) , prosperous and strong fiber: Cross section configuration: Less tooth form, or circle, elliptic; Vertical range pattern: The surface is flowing.
(8) , acetate fibber: Cross section configuration: Trefoil or irregular zigzag; Vertical range pattern: The surface has fore-and-aft streak.
(Fiber of 9) , acrylic fibbers: Cross section configuration: Circle, dumbbell form or foliaceous; Vertical range pattern: The surface flowing or have streak.
(Fiber of 10) , polyvinyl chloride fibber: Cross section configuration: Be close to a circle; Vertical range pattern: The surface is flowing.
(Fiber of black silk ribbon of 11) , ammonia: Cross section configuration: Irregular appearance, have a circle, potato form; Vertical range pattern: The face is dark deep, show unsharpness bone form stripe.
