INFORMATION FOR THE CONSUMER
NATURAL CHARACTERISTICS oF FABRICS
The fabrics used in our awnings are of a high technical quality, both
in terms of weaving and in the manufacture and finish. Despite this,
some can present characteristics that may erroneously be interpreted
as faults.
Customer should therefore be informed that mass-coloured acrylic
fabrics occasionally present the following characteristics:
UNDULATIoNS
Formed in the proximity of seams and side edges. The double
thickness caused by overlapping the fabric after rolling creates
tension which causes the so-called embossing.
CREASES
Wherever the fabric is folded, especially in paler colours, spider web
or marble effects can be created which become darker when seen
against the light and may look like dirt.
PINHoLES
Acrylic fabric is treated with fluorinated resins which, in addition to
guaranteeing the known technical features, also make it stiffer. When
it is used to make cowls, pinholes may form wherever the fabric is
folded (as a consequence of the material's stiffness).
Specialist German associations have conducted a study on
undulations, creasing and pinholes, which concluded that they
cannot be considered as defects.
Therefore, these features cannot be considered a cause for complaint.
These characteristics do not affect the quality of the fabrics.

ACRYLIC FIBRE
Acrylic fabrics have particular technical features:
LIGHTFASTNESS
The organic pigments used for the acrylic have superior lightfastness
Undulations near seams to the disperse dyes used for dyeing polyester.
HIGH ToUGHNESS, LoW FRAGILITY
Polyester absorbs much more UV than acrylic. The higher the
absorption, the less tough and more fragile the fibre.
HIGH DIMENSIoNAL STABILITY
After 1000 hours' exposure to light and inclement weather (UNI-
Undulations in centre of EN 105-B04 test), acrylic retains its initial toughness and elongation
canvas
values; other synthetic fibres decay which, in the case of polyester,
results in up to 50% loss of initial characteristics over the same
period of time.
The top three adjacent photos show acrylic fabric with the addition
of a little honey. Water is then poured over the fabric: the honey
simply slides off the surface leaving the fabric clean.*
Creasing
The bottom three photos show what happens when powdered
coffee is added to the acrylic fabric: water, including rain, removes
the dirt leaving the fabric unchanged.*

nanotechnology.
