3. 1
Types of fibres
The fibres which are obtained
from plants and animals are
known as natural fibre .
Examples of natural fibres are
cotton and jute.
Natural fibres
Fibers are thread-like materials.
Plant fibers are those fibers
which we get from plants.
Fibres which are manufactured in
laboratories and are not directly
obtained from any living source are
called artificial fibres.
Examples: Rayon, Nylon, Polyester,
Acrylic and Aramid.
Artificial fibres
The fibres composed of
mineral substance .
Example of mineral
fibres are
Asbestos,graphite,glass
Mineral fibres Asbestos occurs
naturally as fibres

ABSORBENT COTTON
BIOLOGICAL SOURCE:
Trichomes of seeds of cultivated species of Gossypium herbaceum
Family: Malvaceae
GEOGRAPHICAL SOURCE: India, Egypt,china ,U.S.A
Collection:
 The capsule of cotton consists contains large number of seeds covered with
trichomes.
 The trichomes are separated.
 Long trichomes are used in preparation of fabric & short ones are used in
preparation of surgical dressings.
 This non-absorbent cotton, when treated with dilute soda solution for 10 to 15
hours at a higher pressure, gets free of fats.
 The resulting absorbent cotton is dried, sterilized with gamma radiation.
Kapas
,purified
cotton

5. Character:
 White in colour,soft to touch.
 Odourless,tasteless.
 Absorbentcotton sinks in water whereas
nonabsorbent floats on water.
Chemical constituent
Absorbent cotton contain pure form of Cellulose. Cellulose
molecule is made up of glucose residue united by 1,4-beta
glucosidic link
Uses:
 It is used as surgical dressing.
 Used as filtering media .
 It gives mechanical support to absorb blood,pus, protect wound from
bacterial infection

6. 3
JUTE
Synonym:
Gunny, sutli
Biological Source:
Strands of phloem fibres of the stem bark of Corchorus olitorius Linn. and
Corchorus capsularis Linn. (Family Tiliaceae) constitute Jute.
Geographical Source:
Jute is extensively cultivated as a cash crop in Bangladesh, which supplies
more than 95 percent of the world’s requirement of this important fibre. It
is also cultivated in small quantities in some parts of India.

Retting
Stripping
The retting process consist of bundling of jute stems together and
Immersing them in slow running water
Stripping is the process of
removing the fibres from the stalk
after the completion of retting.

8. USES
In pharmacy Jute is
used for the
manufacture of tows
Jute is used for the
preparation of coarse
bags.
Chemical composition
The chemical composition of jute fiber
includes cellulose (64.4%), hemicellulose
(12%), pectin (0.2%), lignin (11.8%), water
soluble (1.1%), wax (0.5%), and water
(10%).
used as a filtering or straining
medium,Other industrial uses of Jute
include the manufacture of ropes,
gunny bags, carpet

9. Silk
4 Biological source:The silk fibre is prepared from the cocoons of
Bombyx mori Linn, commonly called the mulberry silk worm, and
other species of bombyx.
Family:Bombycidae
Sericulture is the process of cultivating silkworms and extracting silk
from them .The sericulture process follows three primary steps.
 Moriculture – the cultivation of mulberry leaves.
 Silkworm rearing – promoting the growth of the silkworm.
 Silk reeling – the extraction of silk filaments from the silkworm cocoons
Finally, the silk filaments are woven together to form a thread. These threads are often plied
together to form a yarn.
Cultivation

10. Silk mainly consists of
protein known as
fibrion. Fibrion is
soluble in warm water
and on hydrolysis
yields two main amino
acids, glycine and
alanine.
Silk is used pharmaceutically
in the preparation of sutures,
sieves, and ligaturesPt
Chemical test
When flammed it gives
Smell of burnt hairs

11. 5
Wool
Synonyms:
Animal Wool, Sheep’s Wool
Biological Source:
Wool consists of the hairs of the fleece of the sheep, Ovis aries Linn.
family Bovideae
Preparation Of Wool:
The hairs are cut from the sheep at appropriate intervals and dirts removed
by beating on a sieve screen. The dirt-free hairs are then thoroughly
cleansed by washing with soap and sodium carbonate. The wool is then
bleached with sulphur dioxide or hydrogen peroxide, thoroughly washed
and dried by hot air on wire netting.

12. 5
Wool
Constituents:
Wool fibres are composed almost entirely of the protein keratin,
which contains C, H, 0, N, and S.
Uses:
 Wool is used to prepare crepe bandages and dressings and as medium
for filtration and staining.

13. Viscose rayon
6
Synonyms
Rayon, regenerated cellulose., regenerated fibre
Biological Source:
Rayons are prepared from the polysaccharide cellulose molecules derived from wood pulps by
maceration and treatment with various chemical substances
Viscose is just one of the manufacturing process of preparing rayon & rayon produced form
viscose process is called viscose rayon.
Constituents:
Like Cellulose wadding, Viscose rayon is also composed almost entirely of cellulose. It also
contains about 0.03 percent of sulphur and yields about 0.2 to 0.3 percent of ash.

14. Uses
• surgical dressings are made from Viscose rayon.
• Viscose rayon is used to manufacture fabrics, absorben wool.

15. Surgical dresssing
7
surgical dressing is a common word which includes wide range of materials used alone
or in combination for protections, coverings, absorbents or supports to the
wound.Surgical dressing should be easy to handle, sterilizable and free from any loose
threads and fibres.
Surgical dressing are classified as follows:
a. Primary wound dressings
b. Absorbents
c. Bandages
d. Adhesive tapes
e. Protective
Functions of Surgical Dressing:
 It prevent infections.
 It protect to healing wounds.
 It provide mechanical support to tissue.

16. Sutures
8
Sutures and ligatures are the same material. Sutures is a thread used to stich
together the edges of various tissue with the help of needle eg skin, muscle,
tendon, etc but when thread is used to seal off blood vessels, vein or artery by
tieing then thread is known as a
ligature.
Sutures are classified into two main groups
(a) Absorbable
(b) Non- absorbable
Which are absorbed or digested in tissue or
body.example vicryl,dexon,catgut
Which are not absorbed remains in the body
Ex-silk,cotton,

17. Surgical catgut.
Catgut suture is a type of surgical suture that is naturally
degraded by the body's own proteolytic enzymes. Absorption is
complete by 90 days, and full tensile strength remains for at
least 7 days
Ligature
In surgery or medical procedure, a ligature consists of a piece of
thread tied around an anatomical structure, usually a blood vessel
or another hollow structure to shut it off
