Why the Same Dye Recipe Gives Different Results | Virgin PET, Recycled PET & Nylon 66 | S1 E6C

Why can fabrics with the same nominal specification produce different shade, shrinkage, handle and drape? Series 1, Episode 6C explains the upstream RFT evidence chain: requirements, representative sampling, yarn identity, denier per filament, PET intrinsic viscosity, Nylon 66 relative viscosity and amino end groups, moisture, virgin versus recycled PET, crystallinity, accessible amorphous regions, molecular orientation, microvoids and heat-setting history. Presented by Chiata Suni (賈達蘇尼), Textile Chemistry Right First Time System Engineer | Technical Author. 👍 Like | 🔔 Subscribe | ↗️ Share
