PROPERTIES OF MATERIALS
Ԙ
Insulating power. Wool acts as a good
insulator.
Ԙ
Hygroscopicity. Wool absorbs water up
to 30% of its weight.
Ԙ
Low flammability. Wool in contact with
fire slowly chars.
Ԙ
Elasticity and toughness.
Ԙ
Felting. Wool fibres tend to weld and
penetrate.
Ԙ
It is the result of a weave of animal
fibres that possess certain qualities of
natural tendency to blend by weaving
and that, after being treated, connect
closely with each other.
Ԙ
The fibres are woven through
mechanical and chemical processes.
Ԙ
It’s an excellent natural insulation.
Ԙ
Very fine yarn with characteristic shine.
Ԙ
High degree of hygroscopicity.
Ԙ
Good insulation, warm in winter and
cool in summer.
Ԙ
It is an extremely robust fibre, but very
soft to the touch.
Ԙ
Highly hygroscopic.
Ԙ
The fibres are rough and tough and
the yarn is also rough, rigid and very
resistant.
Ԙ
Low extensibility.
Ԙ
High breathability.
Ԙ
Biodegradable and 100% recyclable.

SILK
Ԙ
High hygroscopicity. It absorbs more
moisture than cotton and is liable to
deformation.
Ԙ
Lack of elasticity.
Ԙ
Low resistance to acids, light and
micro-organisms.
Ԙ
Good resistance to moths, organic
solvents and bleaching.
Ԙ
It is an artificial fibre but not synthetic.
Ԙ
It looks very bright.
Ԙ
Natural fibre composed of 70%
cellulose.
Ԙ
Highly hygroscopic.
Ԙ
Low extensibility.
Ԙ
It has a shiny appearance, comes with a
cold and slippery hand.
Ԙ
Biodegradable and 100% recyclable.
Ԙ
High resistance to breakage, abrasion,
light and micro-organisms.
Ԙ
Flexibility, lightness, easy maintenance
and does not degrade over time.
Ԙ
Low absorption coefficient of liquids
and humidit.
