I have used it both top and bobbin in my Bernina with no problems. Is it nylon monofilament? Or polyester monofilament? I know that with nylon monofilament there are some things that help a lot. The same probably holds true of polyester monofilament.

(1) Nylon monofilament stretches easily, which means I need to reduce the top tension from a 5 to a 3. Basically, cut your top tension in half.

(2) If the thread is on a cone, I use a thread net on it, place the cone in a jar behind my machine, and feed it straight up into an outrigger thread guide before it ever goes to the first guide on my machine. You can use a thread stand instead of a jar and the outrigger. I really like the Superior Threads new acrylic thread stand for this purpose. In other words, this thread often needs a pre-guide in order to feed correctly into the top thread guides. At least with a cone, you absolutely need a thread net. If you are using a spool instead of a cone, I'm not sure but a thread net cut to size probably wouldn't hurt and might help. This thread is slippery and has a tendency to fall down the cone and get caught before it feeds. You really need to make sure the thread has an unimpeded path to the needle, because any "glitch" in the feed (and the thread goes in and out of the needle multiple times for a single stitch) will cause thread nests underneath.

(3) If winding a bobbin with this stuff, do it slowly in order not to stretch the thread as it is going on the bobbin.

(4) If using a plastic bobbin, wind only half full. If using a metal bobbin, wind 3/4ths full. Never overfill the bobbin with this thread. Because of its tendency to stretch, winding fast and/or winding a bobbin too full can distort the bobbin's shape, causing numerous unexplainable problems when trying to sew.

Monofilament Thread Properties

Monofilament Spools and Canisters

 

Monofilament thread, also known as invisible nylon, is exactly what its name says - a thread that has a single filament. Monofilament thread is semi-translucent, and it is the first choice for sewing "invisible" stitches. The Monofilament Thread Buying Guide helps customers get the right thread for their needs. Our approach is to help you decide if monofilament thread is right for your needs, identify which sizes (thicknesses) should be used for common monofilament applications, and provide specifications for each size.

Our approach is to help you decide if monofilament thread is right for your needs, identify which sizes (thicknesses) should be used for common monofilament applications, and provide specifications for each size.

Our clear monofilament thread has a semi-translucent quality that helps it to blend in with the fabric that you are sewing. This makes monofilament thread an excellent choice for blind stitching, and making exposed stitches or seams as "invisible" as possible. It is also a good alternative if you cannot find a thread color that matches your fabric. Monofilament thread looks and feels like fishing line, but it is too prone to tangling on reels. Monofilament thread goes up to 0.012 inches, whereas fishing line usually starts at 0.013 inches. For best results, use clear monofilament with light colors and smoke monofilament with dark colors.

Size refers to thread thickness - not the amount of thread on a spool or canister. Our monofilament thread sizes range from almost hair thin and delicate, to sizes strong enough for upholsery. As thickness increases, the thread's strength increases, it becomes more visible, and the yards-per-ounce decrease. Monofilament sizes are usually by the thousandths inch. For example, a size .007 monfilament thread is seven one-thousandths of one inch, or, 7/".

It is becoming more common for monofilament packages to be labeled in Tex and Denier. Equivalent Tex and Denier sizes are listed in the Specifications topic on this page.

Sizes .003 to .011 can be used with most home sewing machines. Size .012 normally requires a commercial machine.

Elongation - Monofilament thread has an average stretch of around 31% over time. This is beneficial for its end use, because it allows for the seams to stretch with the fabric, allowing for 'breaking in'. For activewear and lighter materials, Woolly Nylon thread has a greater stretch. Kevlar Thread has about a 2% stretch.

Heat - Monofilament thread can usually handle continuous heat up to 285F (140C) before breaking down. Its melting point is 509F (265C).

Abrasion - Monofilament thread has excellent abrasion resistance.

Chemicals - Monofilament thread has good resistance to bleaches, solvents, acids, and Alkalis.

Our monofilament thread is mostly sold on large canisters and smaller king spools. The standard monofilament canisters without tops (domes) are usually 5.25 inches at the base, and stand about 7.0 inches tall. Bases and domes for monofilament canisters are sold separately. 2 and 4 Ounce Monofilament king spools average 2.50 inches at the base, and stand about 4.50 inches tall.
