Terminology
1.
Fleece: Fibre coat that covers a sheep.
2.
Lock: A group of fibres clinging together in
fleece.
3.
Greasy wool: Shorn wool with grease and wax
etc. before removal of impurities.
4.
Kemp: A coarse and brittle wool fibre. It has an
irregular medulla.
5.
Keratin: The wool protein is known as keratin. It
contains sulphur.
6.
Crimp: Natural waviness of a wool fibre.
Terminology cont.…
7.
Staple Length: Length of a wool fibre without
disturbing its natural waviness.
8.
Fibre Length: Length of the fibre in stretched
condition.
9.
Suint: Secretions of the sudoriferous glands of
the skin. It is mostly alkaline in nature having
potassium salts.
10.
Lanolin/ Wool wax: Secretions of the sebaceous
glands of the skin.
11.
Wool Yolk: Wool wax with suint- a water soluble
material in raw wool is known as yolk. It is more
in finer wool and increases in winters
Terminology cont.…
12.
Burr: Vegetable matter present in wool is known
as burr.
13.
Scouring: Washing treatment of wool with
detergent (sodium carbonate) or removal of
impurities from raw wool to obtain clean wool
yield.
14.
Carbonization: The process of chemical
treatment of wool for removal of burr.
15.
Shearing/ Clipping: Removal of fleece from the
body of sheep either with a pair of scissors or by
electric shearers.
Terminology cont.…
16.
Sweating: The process of removal of wool by
bacterial digestion of pre-keratinous region of
fibre root or by application of depilatory agent to
the under surface of pelt.
17.
Rooing: Plucking of fleece of indigenous sheep
having double coat under going partial moult or
loosening of the fibre.
18.
Fellmongering: The process of removal of wool
fibres from sheep skin through use of chemical
applications (sodium sulphide) or administration
(10-14 mg of thallium) for artificial moult in
sheep 10-16 days post administration.
Terminology cont.…
19.
Felting: It is defined as the ability of textile
material to undergo irreversible increase in bulk
density when subjected to friction and pressure
under suitable physical conditions.
20.
Secondary/ Primary Ratio: It is the ration of
secondary to primary follicle obtained by
dividing the total number of secondaries by total
number of primaries in a unit area of skin.
21.
Hank: It is a definite length of yarn or thread
which is measure of quality of wool in worsted
system.
Terminology cont.…
22.
Handle: It is measure of fine-ness. A subjective
assessment of diameter of hair with respect to its
tactile qualities.
23.
Count: It is an index of thickness or diameter of
yarn.
24.
Skirting: Removal of objectionable parts and
stains from body of fleece after shearing.
25.
Warp: The longitudinal section of fabrics which
is arranged in a sheety form for the purpose of
interlacing with the longitudinal section of the
fabrics in a particular mode.
Terminology cont.…
26.
Weaving: The technology in which two series of
threads are used to produce a fabric running
longitudinally and the other lattidinally.
27.
Scale: A cuticle of flattened cells protecting the
cortex of fibres.
28.
Fibrion: Silk protein is known as fibrion.
29.
Keratinization: Hardening of previously soft
plastic fibrous protein.
30.
Lea: It is a measure of length and is 1/7 th of
Hank. 1 Lea- 1000 grains & 1 Hank- 7 Lea.
