ARAMID FIRE-RETARDANT THREAD
A staple spun sewing thread made from 100% meta-aramid 1313 fibres. This fire retardant sewing thread is used with clothing and gear designed to protect from fire and heat.
It should only be used with fabrics and materials that have the same level of fire retardance. This thread is expensive and using it for regular sewing is wasteful. They do not melt and can withstand temperatures of 700F (370C) before they decompose. This compares to a 450F (230C) melt point for general purpose threads such as Nylon and Polyester. Fire retardant is not fire-proof. These threads will burn when exposed to a 2500F (1370C) cigarette lighter. They should not be used with conveyer belts and other gear that operates above 700F (370C).
Features:
Decomposition - Fire retardant sewing thread begins to decompose (turn to ash) at about 700F (370C). Much higher than nylon or polyester.
Melting - Fire retardant sewing thread does not melt. Self-extinguishing (stop burning) after the flame has been taken out. This is important in fire retardant gear.
Mildew, Aging, Sunlight, and Abrasion - Excellent resistance to mildew and aging. Prolonged exposure to sunlight causes deterioration. Polyester thread works just as well in some cases. Good abrasion resistance.
