Underthread

Fire Retardant Underthread

To ensure embroidery passes a fire resistant test, the bobbin thread should be of the same composition.

 

We offer two options, both manufactured with Trevira CS.

 

PF102 (dTex 160x2 / Nm 160/2)

A very fine continuous filament underthread, available in white and black.

 

PF72 (dTex 145x2 / Nm 70/2)

For extra resistance use this 100% spun polyester product, available in white and black.
