"6 MONTHS & 3 ROUNDS OF DEVELOPMENT TO GET ONLY THE FABRIC RIGHT"
From Idea to Outcome: The Problems, Tradeoffs, and Final Result
PURCHASE,WEAR SAMPLES & NOTE COMMENTS
"Zara" - Heavyweight T-Shirt
Fabric has good weight. Spandex unravels easily. Sizing = good
"Marco Polo" - Heavyweight T-Shirt
Fabric turns rough after washing 10x. Ribbed collar is interesting
"Uniqlo "- Airism Oversized T-Shirt
Fabric includes polyester on the skin side = Not for the winter season
"COS" - Mock Neck Heavy T-Shirt
Fabric fades after 10 washes. Ribbed mock neck looks overly formal
"ICON" Amsterdam - Heavy Weight T-Shirt
Fabric deforms & fades after washing 5x. Sizing = too informal
CONCLUSION
- Fabric fading prematurely = major issue
- No fabric weartested has truly exceptional softness = potential point of differentiation
- Seams become sloppy after 2 dozen washes = problem to solve
NEXT STEPS
- Start Fabric Development Trial 1
- Start techpack creation
- Decide on garment manufacturing partner
COMMERCIAL REQUIREMENTS/NOTES
- Maximize longetivity of color = Long Staple Fibers
- Reduce pilling effect = Long Staple Fibers
- Some stretch for everyday comfort = 5% Spandex
- Structured Drape For Semi-formal aestethic + Suitable for Cold Climates = 250+ gsm
- Increase skin-side wearing comfort = Double-faced fabric
- Maximize softness = **Redacted** (confidential)
FABRIC MILL SPEC REQUIREMENTS v1
- Raw Material = Supima Cotton
- Material Composition = 95% Cotton & 5% Spandex
- Weight = 270 gsm
- Construction = Doubleknit
- Yarn = **Redacted** (confidential)
WEAR TEST CONCLUSION
- Tester responded postively to "Softness"
- Fabric color is too grey not black enough
- Fabric looks too structured. Not enough drape
NEXT STEPS
- Discuss with mill darken the black color
- Reduce weigth of fabric to increase drape
Heavyweight Fabric Spec
COMMERCIAL REQUIREMENTS/NOTES
- Fabric must be "Super Black"
- Reduce weight of fabric to address drape issues + reduce propensity of seams to rub
- Implement "Blind Preference Testing" on new sample vs Competitor Sample **Redacted**
FABRIC MILL SPEC REQUIREMENTS v2
- Raw Material = Supima Cotton (No change)
- Material Composition = 95% Cotton & 5% Spandex (No Change)
- Weight = 260 gsm (update)
- Construction = Doubleknit (no change)

- Fabric structure is much better. Weartester find it appealing
80% of weartester prefered sample vs competitor garment
NEXT STEPS
- Can we make the black color even blacker
- Seams are still an issue after dozen washes start to fade
COMMERCIAL REQUIREMENTS/NOTES
- Fabric must be "Super Black"
- New sample to be made with "Flatseams" to address seam fading issues
FABRIC MILL SPEC REQUIREMENTS v2
- Raw Material = Supima Cotton (No change)
- Material Composition = 95% Cotton & 5% Spandex (No Change)
- Weight = 260 gsm (Update)
- Construction = Doubleknit (no change)
