When sourcing Cotton Khaki Fabric, the primary focus should be on yarn count and density, which determine the fabric's weight and durability. For high-quality apparel, look for a yarn count of 21s, 32s, or 40s. The weight (GSM - Grams per Square Meter) is critical; standard khaki usually ranges from 180 GSM to 300 GSM. Additionally, verify the weaving method, typically a twill weave (2/1 or 3/1), which provides the characteristic diagonal ribbing and superior abrasion resistance. Ensure the fabric has undergone mercerization to improve luster, strength, and dye affinity.
