A&E is committed to ethically-manufacturing its products. D-Core Core Dyed® Eco is a responsible sustainable, sewing thread choice, engineered to meet the garment overdyeing requirements. In this thread, the polyester core is dyed in final garment color and the cotton wrap is left undyed. During the garment dyeing process, the cotton wrap will pick up the garment color. A&E‘s D-Core Core Dyed® Eco is a sustainable, core spun sewing thread constructed with a continuous filament polyester core and cotton staple wrap. Allowing for the use of smaller thread sizes to minimize puckering or needle cutting, D-Core Core Dyed® Eco’s construction provides a sewing thread with higher strength over traditional, staple spun products. This thread’s cotton wrap delivers superior needle heat resistance and an excellent sewing performance on manual & automatic, multidirectional sewing machines with superior loop formation and fewer skipped stitches.
