Inks, phthalates and PFAS on prints
RSL versus MRSL, phthalate plasticisers, azo dyes and fluorinated DWRs — what a heat-transfer or screen ink must not bring onto the garment.

Wash and stretch of heat transfers
Adhesion, rub fastness, elongation on elastane and what a lab actually measures on a pressed motif.

Antimicrobial and other functional claims
Antibacterial, antistatic and graphene-finish stories on trims — test methods, wash life, and what not to print on a hangtag.

High-visibility apparel trims
EN ISO 20471 classes, fluorescent ground versus retroreflective bands, and why a silver tape does not make a Class 3 vest.

Fibre content and origin on labels
US FTC and EU fibre-name rules at a practical level — tolerances, permanent labels, and why the mill’s verbal is not a test.

Reading eco-marks on trims
GRS, GOTS, OEKO-TEX STANDARD 100 and bluesign — private schemes, what each ticket covers, and what a hangtag icon cannot claim.
