Nylon fibre

Nylon fibre. It is a synthetic fibre invented by DuPont that was used originally for hosiery but in many applications. Nylon is naturally water-repellent, easy to dye, and very strong. These features have helped plastic replace cotton in many industrial uses, like bags and flags.

Dips are used to describe fabric or yarn when in the dye. Indigo yarns dipped in an indigo bath usually 6 times but up to 16 times.
