Textile Fiber Reference

Use When

• You need to identify a woven synthetic fiber from lab clues (burn, DSC, density, FTIR, solubility)
• You need to match a fiber to its compatible dye class and recommended process window
• You need to compare cost and energy profiles across dyeing/finishing pathways

Files

File	Description
fiber-identification-quick-reference.md	Lookup table for identifying PA6, PA66, PET, PBT, CDP, PTT, and spandex from burn behavior, DSC peaks, density, FTIR bands, and solubility tests
fiber-dye-matching-and-process-windows.md	Maps each fiber family to compatible dye classes (disperse, acid, reactive) with indicative temperature, pH, time windows and auxiliary requirements
cost-and-energy-structure-reference.md	Comparative cost and energy data for common dyeing and finishing process pathways — use when evaluating commercial burden trade-offs

Reading Rules

• Treat all numeric values as indicative ranges, not guaranteed setpoints.
• DSC and density values are for oriented fiber; amorphous or drawn variants may shift by 5-15 units.
• Dye process windows assume standard atmospheric or HT jet equipment; beam or pad routes may differ.
• Cost data are relative indexes, not absolute prices — use for ranking, not quoting.
• When multiple fibers match a clue, use the elimination logic described in the identification reference rather than picking the first match.
