Gentle, Cost-Efficient Decolouring of Reactive-Dyed Cotton

Process

We follow a structured Venture Client process.

1. Application via Platform

Solution providers submit their application through the ekipa platform until the deadline.

2. Get-to-Know Conversations

Short digital sessions (30–45 minutes) with selected providers to:

• clarify open questions about the solution
• discuss feasibility within the textile finishing process and equipment
• align on a potential PoC direction

3. Request for Proposal (RFP)

Shortlisted providers are asked to submit an RFP based on:

• defined PoC objectives and success criteria (decolouration + fibre integrity)
• scope, budget and timeline
• responsibilities

RFPs will be reviewed and successful candidates will move into the PoC stage.

4. PoC Building / Pilot

The PoC is executed on standard cotton samples so that results can be objectively measured.

CHT Group provides:

• standard cotton textile samples with known fibre properties (and/or real customer samples to be decoloured)
• relevant textile and application context, plus existing stripping-method recipes as a technical benchmark
• objective measurement of fibre integrity and decolouration using established textile test methods
• textile and process expertise for joint development

The PoC focuses on:

• validating effective dye removal on reactive-dyed cotton
• measuring that fibre strength is preserved (gentleness)
• assessing process cost, temperature, cycle time and equipment compatibility

5. Rollout Evaluation & Next Steps

Based on PoC results, CHT Group evaluates:

• continuation or adjustment of the process
• joint development toward a market-ready product
• commercial model (supply, licensing) and scaling options, including exclusivity

A successful PoC can directly lead to an extended development partnership.
