Test 3: Mapping function to different materials

Background
All materials behave differently, especially when it comes to odor, stains, and refreshing. This test mapped how Pure Effect Textile Spray works on different fabric types and in real reuse flows. The goal was to see which materials respond best to the spray, and which require other handling.

Why
If we know how different fibers react, we can optimize usage and save more garments from being unnecessarily discarded. The test contributes to building knowledge for future circular sorting and reconditioning, where clothes get a longer life instead of export or waste.

Method
The test was divided into three parts:
1. How many garments can be saved in a sorting flow using the spray?
2. How does the spray work against different types of odors on various materials?
3. How are fresh stains affected on different materials and structures?
Over 250 kg of textiles were sorted, 30 kg were sorted out due to odor or stains, of which 3 kg were treated and evaluated after repeated applications of the spray. 

Results & insights
The textile spray worked particularly well on cellulose-based materials (cotton, viscose, lyocell) when it came to odor, especially cigarette, sweat, and second-hand odors. For fresh stains, synthetic materials like polyester showed the best results: pesto, coffee, and red wine almost completely disappeared. Old or dried-in stains were more difficult but lightened over time.

Lessons Learned
The spray can make a difference in the sorting process – both for odor and appearance. However, it requires resources for application and working with the textile. With correct application, up to 1 out of 3 kg of textiles can be saved for reuse. This opens up new, circular opportunities where bacteria become part of future textile care. The main lesson is that the spray has the most impact the closer it is to the consumer and the fresher the odor or stain is.
