6. • ADVANTAGES OF JUTE FIBERS
• Under stress jute extends only 0.5% to its stable
form and so gives wonderful dimensional stability.

sunlight is used.
• If Jute is wetted it lose it’s strength

15. • ADVANTAGES OF ACRYLIC FIBER
•
•
•
•
They are light weight but have more bulk.
They are odor and mildew resistant too
Cleans easily.
A transparency rate of 93% makes acrylic the
clearest material known.
• DISADVANTAGES OF ACRYLIC FIBER
• It is more expensive than glass.
• If exposed to a direct flame it will melt and
eventually burn.

27. SPANDEX (LYCRA)
• Monofilament yarn
• Spandex or elastane or elastomeric fiber is
a synthetic fiber known for its
exceptional elasticity.
• The name "spandex" is an anagram of the
word "expands". It is the preferred name
in North America; in continental Europe it is
referred to by variants of "elastane",

30. ADVANTAGES OF LYCRA
• IT IS USED IN CLOTHING BECAUSE ITS LIGHTWEIGHT,
COMFORTABLE, AND BREATHABLE.
• DUE TO ITS FITTING NATURE IT IS OFTEN USED IN
WOMEN'S CLOTHING RATHER THAN IN MEN'S CLOTHING.
• IT DRIES QUICKLY, MOISTURE WICKING AND IT IS EASY TO
DYE.
• IT HAS BACTERIA RESISTANT NATURE, BLOCKS ULTRAVIOLET
RAYS AND SO IT IS USED IN GARMENTS.
• GARMENTS THAT ARE MADE USING LYCRA ARE
SOCKS, SWIMWEAR, EXERCISE CLOTHING AND LEGGINGS.

31. DISADVANTAGES OF LYCRA
• SINCE IT IS TIGHT-FITTING, NON-CYCLISTS FEEL HARD
TO ACCEPT ITS APPEARANCE.
• SOCIAL ACCEPTANCE OF THIS TIGHT-FITTING IS STILL
SLOWLY BEING IMPLEMENTED.
• IF THE LYCRA IS BEING USED AS A BASE FOR GLUING,
AS MIGHT BE THE CASE IN A FOAM BODYSUIT, THE
GLUE WILL TEND NOT TO SOAK IN THE FIBERS AND YOU
WILL NOT GET GOOD ADHERENCE.

33. COTTON
• Cotton is a soft, fluffy
staple fiber that grows in a boll,
Under natural conditions, the cotton
bolls will tend to increase the
dispersion of the seeds.
• ply- 6
• Twist- S

yellowish white or grey.
Textile Strength
3.5gm/den.

35. PHYSICAL PROPERTIES OF COTTON
Elastic Recovery
It is inelastic and rigid fiber
Effect of Sunlight
gradual loss of strength
when cotton is exposed to
sunlight and the fiber turns
yellow.
Effect of age
It shows a small loss of
strength when stored
carefully
Effect of Heat
cotton is severely damaged
after few minutes at 240ºC

36. BURNING TEST OF COTTON
In Flame
Ignites immediately
Removed From Flame
Continues to burn
Odor

37. ADVANTAGES OF COTTON
• Environmentally friendly
• Durable
• Soft
DISADVANTAGES OF COTTON
• Cotton clothes will begin to fade after a few
years, particularly if left in direct sunlight.
• Cotton is not a very weatherproof fabric. If left
outside it is also likely to be damaged by mold
and mildew. Man-made fabrics tend to be
much tougher, and mold resistant
