| Glass
fibre fabrics are made in three basic weave patterns :plain
weave, twill weave satin weave. The other weave patterns are
derived from these. |
|
| Plain
weave (linean weave) |
|
The weft thread passes successively above then beneath each
warp thread, and the inversely in the following pass. |
 |
|
| Twill
weaves |
| The
warp and weft threads are crossed in a programmed sequence
and frequency in order to obtain the diagonal lines characteristic
of this type of weave. |
 |
|
| Satin
weaves |
|
The
warp and weft threads are crossed in a programmed order
and frequency in order to obtain a flat appearance, since
the linked points are not arranged continuously. As a result
one side of the fabric has more warp threads whilst the
back appears to consist mainly of weft threads, the higher
the satin number(7satin,8satin….),the higher the count of
warp and weft threads.
Satin
weaves allows production of fibres with high mass per unit
of surface area and good drapability.

|
|
| Unidirectional
weaves |
| The
number of threads is considerably higher in one direction
then in the other(unidirectional warp fabric or unidirectional
weft fabric).The theads are parallel and are simply held together. |
 |
|
| Special
weave patterns |
|
Gauze
weave : Two
warp threads are taken around the weft threads, alternately
to the right and left. There
is a wide variety of fabrics held together more or less
closely by points (gauze weave) with plain links. These
patterns produce a decorative effect used principally in
veils.
|
 |
| Bidirectional
deformable pattern: Any
crimp in the threads is eliminated. The threads are arranged
in plies placed at 900 to each other and bound
together by a thin thread representing less than 10% of the
total. (weave7.jpg)
