Prime Preparation Of Machine; Selection Of Needles And Threads - White 404 Instruction Booklet

SELECTION OF NEEDLES AND THREADS
The needle and thread you choose depends
upon the fabric you are stitching. The correct
selection of needle and thread is very important
to avoid damaging the fabrics of light weight,
or
tightly
woven
fabrics, and
to prevent
skipstitches when sewing on very sheer stretchy
fabrics or needle breakage when stitching heavy
or stiff fabrics. For best results, sewing machine
needles should be replaced 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 ball point needle is recommended for use
with tricots, jerseys, lingeries and power nets.
Unlike sharp 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 satisfactory stitching.
Although it is recommended to use a ball point
needle for knit fabrics, when sewing on very
stretchy fabrics of knits, the underlay of a thin
paper below 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 good
quality thread without knots for best stitches.
