Important facts about Thread and Needles
The thread is chosen according to its intended use. For a perfect sewing result,
thread and fabric quality play an important role. Use of quality brands is
recommended.
Cotton Thread
► cotton thread has the advantage of being a natural fiber and is therefore
particularly suited for sewing cotton fabrics
► mercerized cotton thread has a slight sheen and is preshrunk
Polyester Thread
► polyester thread has a high tensile strength and is particularly colorfast
► polyester thread is more resiliant than cotton thread and is recommended
where a strong and elastic seam is required
Thread
Correct Combination
To sew optimally, the thread should travel smoothly down the long groove on
the front of the needle.
Thread Too Thin or Needle Too Thick
The thread has too much clearance in the groove; there may be skipped
stitches or damage to the thread.
Thread Too Thick or Needle Too Thin
The thread rubs on the edges of the groove and can get jammed. This can
break the thread.
Needle/Thread
Needle, Thread and Fabric
Care should be taken when matching the needle and thread.
The correct needle size does not just depend on the thread selected but also
on the fabric to be used. The fabric weight and type determines which thread
weight, needle size and needle tip to use.
Checking Needle Condition
The condition of the sewing needle should be
checked and the needle replaced regularly.
A defective needle does not just damage the
fabric but also the sewing computer.
As a guide:
Replace the needle before starting a new
sewing project.
