I got a new catalog from Threadworx and it had a great sheet about caring for their threads. I’d like to share it with you.
Colorfastness: First off Threadworx’ new threads are all colorfast according to industry standards. New threads have a label with “cf” inside a shaded blue box. Older threads that are colorfast have a red dot.
If one of these is not on the label, the color is not color fast.
Washing: Do not wash these threads in anything but cold water. They are not colorfast in hot water. Threadworx recommends using mild dishwashing detergent and hand wash. They do not recommend using detergent for fine washables (i.e. Woolite).
Further Care: They also have some other things not to do:
- Do not steam.
- Do not tumble dry.
- Do not wring.
- Do not dry clean.
If bleeding occurs: Soak in cool water, changing water every 1-2 hours until the stains disappears.
This is excellent advice for caring for many of the threads we use that are colorfast.
