Exploring the distinct physico-mechanical characteristics of bio-polymer based chambray fabric

Denim is known for its strength and longevity whereas chambray is softer, more comfortable and often used for trendy garments. This research work compares the physical and mechanical properties of bio-polymer based organic cotton (100 %) denim and organic cotton (100 %) chambray fabric. While the both fabrics had identical warp and weft counts, denim had a higher ends per inch (EPI) and picks per inch (PPI) despite having a comparable construction. Denim has a higher (5.65 %) grams per square meter (GSM) than chambray which in turn allows for greater dye absorption. While chambray had a lower tensile and bursting strength than bio-polymer based 100 % cotton denim in the warp direction, the weft direction showed the reverse. Additionally, denim performed much better in the tear strength test (6.29 %). Chambray fabric, on the other hand exhibited less pilling behaviour. The abrasion resistance test yielded excellent results for chambray fabric. The results show that denim is stronger, more compact and more durable, making it better suited for tough conditions. In contrast, chambray offers a softer feel, better breathability and greater comfort in summer, along with a distinct look for coloration.
