The material, which consists fibrous structure and
length is thousand times higher than its width is
called FIBER.

4. PINA FIBER
Man has always been innovative. When talking
of textile fibers, man has made natural fibers from
many plants. One of such inventions is Pina, a texti
le fiber obtained from pineapple leaves for making
fabric.

5. • Piña is a fiber made from the leaves of a pineapp
le plant and is commonly used in the Philippines.
It is sometimes combined with silk or polyester t
o create a textile fabric.
• Pina's name comes from the Spanish word piña
which literally means Pineapple.
• piña fabric is hand loomed by only a few weaver,
it is very precious and scarce, which also makes it
expensive.

6. Classification of pineapple
Kingdom Plante
(Unranked) Angiosperms
(Unranked) Monocots
(Unranked) Commelinids
Order Poales
Family Bromelioideae
Subfamily Bromelioideae
Genus Ananas
Species A.comosus

7. Cultivation method of PINA FIBER
1.Since piña is from a leaf,
the leaf has to be cut first from
the plant.
2.Then the fiber is pulled or
split away from the leaf.

8. 3. Most leaf fibers are long
and stiff. Each strand of the piña
fiber is hand scraped and is knot
ted one by one to form a contin
uous filament to be hand woven.
4. piña is intensive, as each
step is done mostly by hand.

10. Steps: extraction of fiber

11. Physical Properties of pina fiber
Length(mm) 3-9
Breadth(10-3 mm) 4-8
L/B ratio 450
Gravimetric Fineness(tex) 1.54
Tenacity(gm/tex) 50
Extension at break(%) 2-6
Flextural rigidity(dyne cm-2) 3.8
Density (Gm/cc) 1.48
Moisture Regain at 65%
Pineapple leaf fiber is multi-ce
llular with an average ultimate
cell length of 5 mm. The fiber
is lignocelluloses in nature.

12. Chemical Properties of pina fiber
It has been found that P
ALF consists of following
chemical entities
Holo cellulose 87.56%
Alpha-cellulose 78.11%
Hemicellulose 9.45%
Lignin 4.78%

14. Advantages of PINA fiber and cloth
• The fabric has a natural gloss similar to silk, and
is better in quality. This gloss protects the fibers
and as a result, piña does not require any to trea
tment with toxic chemicals.
• It is easy to wash and care for; no dry cleaning
required!
• Piña cloth is wear-resistant.
• It is an ideal eco-textile for clothing
• Pina fiber Long, fine, lustrous.

15. How to take care of Pina Fabric?
1. Dissolve a small amount of mild detergent in
warm water.
2. Soak to free dirt and stains, then gently hand
wash. If the fabric has yellowed, add vinegar to the
water and soak overnight.
3. Use a soft toothbrush to scrub off stubborn dirt.
4. Rinse in an up/down dipping motion. Do not twist
or wring.
5. Hang (on plastic hanger) and shape to drip dry or
lay flat to dry.

16. Various uses of PINA fiber
piña fabric is converted into valuable items
such as Barong Tagalog, kimona, vestments,
table linen, pillow cases, gowns, shawls, fans
and other items.
