Nylon monofilament and Nylon braid sutures are inert, non-absorbable, sterile sutures composed of the long-chain aliphatic polymers Nylon 6 and Nylon 6.6. The braided sutures are coated uniformly with silicone to enhance handling characteristics, ease of passage through tissue and reduction of capillarity. Nylon monofilament / Nylon braid sutures are non-absorbable nylon surgical sutures which are available either dyed black (with Logwood extract), undyed (clear) or dyed blue. Nylon monofilament and Nylon Braid nylon sutures meet all requirements established by the United States Pharmacopeia (USP).
