Technical knowledge
for fabric development.

Practical guides for performance apparel brands navigating fabric selection, construction decisions, and material sourcing.

01

China+1 Apparel Sourcing and Fabric Development: Why the Factory Moved but the Fabric Didn't

Why the China+1 sourcing strategy shifted garment assembly but not fabric supply — and what that means for performance fabric development, supplier relationships, and tariffs.

02

Does Water-Repellent Finishing Make Performance Fabric Less Breathable?

Whether durable water-repellent (DWR) finishing reduces breathability in performance fabric, what PFAS-free DWR changes, and how to brief the tradeoff.

03

Why Some Fabrics Feel Cooler Than Others, and Why It's Not Just About Wicking Speed

How evaporative cooling efficiency is measured in performance fabric, why polyester and cotton cool the body differently, and what it means for fabric selection.

04

Engineering Merino Wool for Performance: How Blends Work and Why They Matter

How merino wool blends with nylon, spandex, and other fibers for performance apparel. What each blend achieves and how to choose for your product.

05

Nylon-Spandex vs. Polyester-Spandex: How to Choose the Right Stretch Fabric for Performance Apparel

Compare nylon-spandex and polyester-spandex for activewear: hand feel, moisture wicking, stretch recovery, durability, and cost. A practical sourcing guide.

06

Single Jersey vs. Interlock: Choosing the Right Knit Structure for Performance Apparel

A practical comparison of single jersey and interlock knit structures for activewear. Understand weight, stretch, stability, and which fits your product brief.

07

Why One Test Number Can't Tell You How Well a Fabric System Breathes

Why relying on a single lab metric like total heat loss can misrepresent real-world breathability, and what a more rigorous testing approach looks like.

08

Why Activewear Fabric Clings When You Sweat, and How to Design Around It

Why sweaty activewear clings to skin, what the research shows about which fabrics cling least, and how to specify low-wet-cling performance knits.
