Thread comes in many styles, weights, and compositions. Understanding the differences can help determine the appropriate thread for the job.
NOTE: Manufacturers and suppliers often have fact sheets with sewing tips, design settings, and needle recommendations on their websites. This is very useful in learning to use a variety of thread types.
Thread comes in a few compositions. These have different properties that can drastically affect sewing and quality.
Polyester
Polyester thread has become the standard thread for Melco embroidery machine users.
-
Stronger than other threads
-
Fewer thread breaks when sewing
-
Colourfast and resistant to chlorine making it ideal for garments that are washed frequently. It is perfect for uniforms and corporate apparel.
-
Comes in a wide variety of colours
NOTE: Polyester thread is recommended for use with your machine to achieve full sew speed and prevent thread breaks.
Metallic
Metallic threads are often used to add a bit of sparkle to a design.
-
High sheen or sometimes a matte finish
-
Can be more problematic to sew with
-
Requires lighter densities and longer stitch lengths
-
Usually requires slower sew speeds and larger needles
Wool/Acrylic Blend
Usually a heavier thread, these threads can be used for a more natural or hand look.
-
Unique look
-
Can be more problematic to sew with
-
Requires much lighter densities and longer stitch lengths
-
Usually requires slower sew speeds and larger needles
Rayon
Rayon threads are made of natural fibers and can have slightly higher sheens than polyester.
-
Wide variety of colours
-
Beautiful Sheen
-
Less strength than polyester
-
Not chlorine resistant
-
Usually requires slower sew speeds.
Thread Weight (Thickness)
Thread is commonly referred to by its weight. In many cases, this is a number beside the type. For example, you might find a “Poly 40”. This number usually means that it would require 40 kilometres of thread to weigh 1 kilogram. With this method, the higher the number, the thinner the thread.
-
40 weight thread is the industry standard for embroidery. Most stock designs are digitized for use with 40 weight.
-
60 weight thread is excellent for fine details and small lettering.
-
12 weight thread is very thick and can work well for a hand embroidery look.
Each thread weight will require different needles and design specifications.
