and return to its natural shape. Quality wool garments look good for longer.
 modern wool can be machine-washed; retaining a small amount of natural oil, wool fiber
resists dirt and grease.
 wool acclimatizes to its surroundings.
 Wool is a bad conductor of heat so when we wear a woolen cloth. it does not allow the
heat of our body to go out and it keep us warm.
 One way to stay warm during cold winter months is by wearing wool clothing..

 Raw cashmere comes naturally from the goat in only the three colors of white, gray
and brown.
 fineness of each strand of cashmere is typically between 7 and 19 microns with an

8-HEMP FIBER
 The fiber is one of the most valuable parts of
the hemp plant. It is commonly called bast,
which refers to the fibers which grow on the
outside of the plant's stalk.
 Bast fibers give the plants strength.

PROPERTIES & USES OF HEMP FIBER
 Hemp fibers can be between approximately 0.91 m (3 ft) and 4.6 m (15
ft) long.
 the hemp may naturally be creamy white, brown, gray, black or green.
 Diameter of hemp fiber is 22 to 25 m.
 Hemp fiber fineness is 0.25 to 0.52 tex.
 Tensile strength is 0.53 to 0.62 N/tex.
 Elongation of hemp fiber is 3 to 4%.
 Specific weight of hemp fiber is 1.47 g/cm^3.
 Fiber length is 15 to 25 mm.
 Hemp is among the longest, strongest, most elastic, and most durable
fibers in nature.
 1 acre of hemp will produce as much fiber as 2 to 3 acres of cotton.
 Hemp is used in housing construction.
 Hemp may be grown also for food (the seed).
 Both the complete protein and the oils contained in hempseeds.
 Fuel can be a by-product of hemp cultivation.
 Hemp use dates back to the Stone Age.
