ABSTRACT:
An ink for marking any fabric, which fades to disappear after use, employs a phthalein color. The fading time which is suitable for the marking ink can be regulated by the addition of ethanolamines and lower alcohols so that the phthalein color disappears naturally after from several hours to about 10 days.
When a suitable ink for marking is used to mark a fabric, sewing may be followed according to the mark, and the mark disappears after a lapse of a determined time after the sewing operation is ended.
The ink does not cause damage to the fabric.
