Good needle for metallic thread. It has a larger eye, which allows the thread to easily pass through
the eye. It is used to sew canvas and belts too since it is a very stiff needle.
Tip:
The point must be able to pierce through the fabric easily to avoid deflecting when the needle contacts
the material. Otherwise, the needle will strike the surrounding metal or the needle plate, potentially causing
damage to the needle or the machine. Choose a finer blade for more fine-woven or knit fabrics. Use a larger
blade for tough fabrics that could cause needle deflection.
Good needle for the newer tech garments. It is used to sew moisture management (wicking),
anti-bacterial and body temperature management garments, such as t-shirts and golf shirts.
Good needle for very light or delicate materials. It is used to sew silks and fi ne linens. It is also
used to sew detailed designs on small areas, such as intricate patches or very small lettering.
Good needle for heavy materials. It is used to sew heavy canvas, vinyl, light leather, ball caps,
visors and more.
Most sewing and embroidery needles have chromium plating that enhances durability and appearance.
Titanium-coated needles are more expensive than chromium-plated needles, but they can last as
much as five to seven times longer than their chromium-plated counterparts. These types of needles
also reduce thread friction. Reduced thread friction lessens the frequency of thread breaks, and saves
time and labor. Titanium needles are a beautiful golden color and are available in the most popular
sizes.
In order for the needle to penetrate cleanly through the
fabric, it is necessary to choose the correct point type. The
types of needlepoints used for commercial embroidery
include:
1. Acute round point – designation SPI
• Has a slender sharp point
• Used on fabric with high thread counts,
microfibers and certain synthetics
