Kotton Fabric
Kotton Fabric (the in-game spelling; players often type “cotton”) is a reusable filter cloth worth 65 credits. It strains coarse particles, such as mushed plant matter, out of liquids, which makes it a standard step in drug chemistry. The game says it is far too coarse for water purification.

What does Kotton Fabric filter?
A filter only catches particles at least as large as its filter size. Kotton Fabric has size 150, so it catches only the coarsest items in the liquid table: Dream Cap Mush, Nightmare Cap Mush, Coffee Mush, Plant Matter and Debris (all size 200). It does not touch Physical Contaminant (100), microbes (50), minerals (30) or any dissolved extract (size 5). That is why it removes plant residue from an extract without taking the extract with it.
Each batch of caught material wears the fabric down. By the code’s default values a step uses 2 durability and removes 1 ml, so a fresh cloth should handle on the order of 500 ml of coarse matter. This is derived from defaults, not read from a tooltip.
How is it used in chemistry?
In the Dream Dust recipe it is the strain step between heating and evaporating. See the chemistry guide for the full sequence and temperatures. Skipping the strain leaves plant matter in the residue and lowers purity.
Where do I get Kotton Fabric?
- Hydroponics. The Kotton Auto Loom Hydroponic Module (200 credits) makes a grown Kotton plant yield fabric instead of Kotton Fiber, at the cost of -50% Performance and -100% Efficiency. See hydroponics.
- Starting kits. The Retired Chemist network upgrade and the Chemist specialization start include a piece.
- Visitors. The Supply Runner always has one among his goods. The Shady Farmer (75%), the Retired Chemist (75%) and the Scavenger (15%) may carry it. An Addict barter offer can give 2 pieces (8% chance when offers are generated).
- Scavenging. The materials loot table gives Kotton Fabric 12.5% of the time, which applies when the Dumping Ground roll lands on materials.
FAQ
Can I purify water with Kotton Fabric? No. Water filters use a much finer mesh (size 22). Kotton Fabric is only for coarse particles.
Does it wear out? Yes, it has 1000 durability and loses some for every strained batch.
Why does the game say “Kotton”? It is the in-game name for the fiber crop. Searching “cotton” will not find the item in menus.
