Textiles Applications Development & Technical Service Labs

Before Eastman Naia™ Cellulosic Yarn becomes a fashion statement, it’s a renewable wood pulp sourced from sustainably managed forests. Using world-class technology, Eastman’s scientists chemically alter the pulp to ultimately create a fiber.

Inside Eastman’s Textiles Applications Development & Technical Service Labs, that fiber goes through three labs – Knitting; Dyeing and Finishing; and Physical and Mechanical Testing – before the yarn products are sold to buyers to become fabric products.

In the Knitting Lab, yarn products made by Eastman, including Eastman Naia™ Cellulosic Yarn and Eastman Avra™ Performance Fibers, are converted to fabric concepts.

In the Dyeing and Finishing Lab, the fabric is prepared for dyeing. Often, a wicking treatment, a softening treatment, or a wrinkle resistant treatment is applied to the fabric.

The Physical and Mechanical Testing Lab is considered the “proving grounds,” where the fabric is evaluated for strength, durability, and comfort. Here, a fabric can be tested for standard methods such as burst, tear, or tensile strength; moisture wicking or drying rate; stiffness; cool/warm touch sensation; thermal or water vapor resistance; and pilling and abrasion. Fabric will also undergo a range of dye fastness or colorfastness tests.
