SELECTION
OF
NEEDLES AND THREADS
PRIWE PREPARATION OF MACHINES
The needle and tiiread you choose depends
upon the" fabric you are stitching. The correct
selection of needle and thread is very important
to avoid damaging light weight or tightly woven
fabrics, to prevent skipped stitches when sewing
on very sheer, stretchy fabrics or needle breakage
when stitching heavy or stiff fabrics. For best
results, sewing machine needles should be replarad
when they become even slightly dull or bent
or at the completion of every other garment.
A regular needle is suggested for use with
woven fabrics. Needles, style 15 x 1, of the
range in size from 8 to 20 are used on this
machine. The lower number indicates the finer
needle. The most commonly used sizes are 11
and 14.
A bail point needle is recommended for use
with tricots, jerseys, lingeries and power nets.
Unlike
diarp
pointed
needles,
which
pierce
fibers of knit fabrics destroying elasticity,the
ball point needle slips between fibers without
damage to fabric and skipped stitches.
A wedge point needle is recommended for use
with leather and leather-look vinyls. A wedge
cutting point pierces leather more easily than
ordinary sewing machine needles, resulting in
more satisiactory stitching.
Although a ball point needle is recommended
for knit fabrics and sewing on very stretchy
fabrics of knits, the placement of a thin paper
under the fabric and the use of a finer needle
are suggested to prevent skip stitches.
Always use the same type and size of thread
in both needle and bobbin. Use a good quality
thread without knots for best stitches.
