Nylon Thread - Why Nylon Isn't Recommended

"Fusible Thread is Nylon, made to melt." "MonoPoly is an invisible Polyester much like the Invisible Nylon on the market, but with much more added benefits."

Here's an explanation of Nylon vs. Poly

Nylon thread should not exist in your sewing supplies unless you want the thread to melt. Nylon threads, whether they are woollie-type threads or invisible monofilament threads, have a very low melting temperature, discolor or "yellow" over time, and go brittle.

Polyester threads exist in both the woollie-type and the invisible monofilament. Polyester has a high heat tolerance, will not discolor, or go yellow.

One more thing to check: If your monofilament thread is labeled "polyamide," that is not polyester, but the chemical name for nylon. Don't be fooled.

Superior Threads does not carry a Nylon Invisible Monofilament thread.  Our Monopoly is Polyester and therefore is dryer safe, won't yellow, won't go brittle over time, & can be ironed on a lower heat setting.  We suggest using a Polyester Invisible Monofilament thread over Nylon for these reasons.
