What are the signs that indicate the starch-based resist paste is completely dry and ready for the dyeing process?
To determine if the starch-based resist paste used in Yūzen dyeing is completely dry and ready for the dyeing process, you can look for several key indicators:
Texture and Appearance: The paste should appear completely dry and have a uniform texture. It should not have any wet or translucent spots. The surface should be smooth and even, indicating that the moisture has evaporated completely.
Stiffness: The fabric with the dried paste should feel stiff to the touch. This stiffness is a good sign that the paste has set and is ready for dyeing. If the fabric still feels soft or pliable, it may need more time to dry.

Cracking: In some cases, especially with certain types of pastes, you might notice slight cracking on the surface of the paste. This can be a natural part of the drying process and is often a sign that the paste is thoroughly dry.
Color Change: The color of the paste may change slightly as it dries, becoming more opaque and less translucent. This change in color can be another indicator that the paste is ready for dyeing.
