100% cotton, two grades. Same tag, one's half the price.
A week sorting bolts at a cotton mill warehouse. Same "100% Cotton" label on stacks priced 40% apart.
Both are cotton. One got combed after carding, an extra pass that pulls fibers under 1/2 inch and the neps with them. The other skipped it. Both legal to call 100% cotton.
The test sellers don't want you doing:
Single layer, pulled taut, held against a bare bulb. Combed blocks your hand outline, the weave reads as one plane. Carded lets the shadow through, you see thin spots and slubs scattered across. 5 seconds, no equipment, can't be faked at the bolt.
Surface fuzz is the other tell, but dye hides it. The pink swatches at the mill showed nothing. The natural and cream ones, you could see neps standing up off the weave when held sideways under the lamp.
Tag won't save you. 100% Cotton alone means carded by default. Combed gets called out, Combed, Combed Ring-Spun, or a yarn count like 40s/60s/80s. No count printed, assume the cheaper one.
Anyone here buying online, do you ask for undyed swatches before ordering, or just eat the gamble on the pink and pastel bolts?
