Introduction
A landmark study in Forensic Science International reveals ”forensic-grade wool felt swabs” capture 83% more epithelial cells than cotton – revolutionizing evidence collection. 37 countries now mandate wool felt in crime scene kits following Interpol’s 2025 standards update.

Technical Advantages

• Electrostatic wool felt fibers attract micron-level skin particles
• Natural lanolin preserves DNA integrity at crime scenes (98% viability after 72hrs)
• Color-coded ”tamper-proof felt seals” prevent chain-of-custody breaches

“Where cotton pushes evidence deeper, textured wool felt traps lift intact samples,” explains Dr. Lena Petrova, lead researcher at Europol’s Forensic Directorate. Her team developed ”magnetic wool felt dusting pads” that collect gunshot residue 5x more efficiently.

Case Study
The Vienna Art Heist (2024) was solved using ”micro-filament wool felt” that captured:

• 7 skin cells from a glove impression
• Mineral traces matching the thief’s motorcycle routes
• Synthetic fibers from a disguise costume

Industry Transformation

• Supply Boom: ”Laboratory wool felt suppliers” report 400% contract growth
• Training: FBI Academy adds ”advanced felt forensics” certification
• New Products: SciFelt’s ”UV-reactive wool felt lifters” for trace evidence
