A fully procedural "unfolding spiral" setup in GeoNodes.

Video demo here.

Any custom (drawn or generated) curve can be folded up and unfolded into a spiral, can be shaped by Curve Radius, and textured as one, continuous spline.

It comes with the full setup with additional examples.

The setup is only one example of using this node tree, you can utilize your own custom curves, shape them and bevel them in the node setup to your desire, and apply your own material to it. (The generated UV Map is exposed to an Attribute, and accessible in the Shader Editor)

Happy Blending !

This is one of the three spiral curve setups:

1.  The Peel - "Stem and Peel" spiral effect to any curve in Geometry Nodes

2. Unfold - Spiral Any Curve In Geonodes

3. The Curl - Unified Unfolding Spiral Setup In Geometry Nodes

An additional setup, creating actually seamless Curve UV Map for curves generated in Geometry Nodes can be found here.

NOTE

-(Since it is a concept demonstration, it is kept as simple as possible.) The GeoNodes trees are kept clean for easier readability and have detailed explanations. Everything is built from the base. The point of these setups is to provide a base core of the concept, node from node, instead of contracting all into node groups with exposed settings, which makes everything harder to read and dissect.

You can embellish, refine as you wish based on the core or realize your own ideas.

-Read the text description, it has a lot of useful info !

- It can be applied to "any curve" ! Meaning, that the setup works by taking a curve, then modifying it into an unfolding spiral, beveling, shaping and texturing it.  Modify the relevant parts (like the resultant shape, length, resolution) to achieve your desired effect ! (The UV Map of the result is exposed to the Shader editor, so you can use any material, you wish !)
