#69 Bonded 3 ply Nylon Thread - Neon Pink is known for it's excellent sewability, high strength, resistance to abrasion, wear and its controlled stretch and recovery properties. 69 Nylon Thread is unaffected by mildew or rot. This thread is finished with a combination of waxes, silicones and oils that are specially designed to facilitate the sewing operation. They provide consistent machine tensions and loop formation and afford protection from needle heat to ensure good sewability and to prevent the fusing of thread and fabric yarns. This treatment bonds the individual filaments and plies together and guards against abrasion and unraveling of threads during sewing.
