Sewing Threads for Workwear

Industrial sewing threads for workwear production - flame-retardant and polyester ranges matched to the fabrics and seams they are stitched into.

Thread is the cheapest component in a protective garment and the one most likely to void it — ordinary polyester melts at temperatures the FR shell survives, opening the seams exactly when they are needed. This range covers both flame-retardant and polyester sewing threads: 11 published articles, with OEKO-TEX STANDARD 100 on selected ranges. FR thread belongs in any garment certified to EN ISO 11612 or EN ISO 11611; polyester thread suits standard workwear, uniforms and outdoor garments.
