Cotton Coils
Cotton rope is very soft to touch, lightweight and easy to handle.
It responds well to dye, and is widely used for decorative and handicraft applications.
It has a very low tensile strength and is ideal for light load applications including animal halters, toys for pets, sash cords.
Key properties at a glance:
- Twisted 3-strand construction
- Made from natural fibres
- Responds very well to dye
- Poor water and rot resistance
- Store in a dry place
- Excellent knot stability & handling qualities
