Combing removes some shorter fibers during yarn preparation. “Combed” or “carded” describes part of the yarn process; neither label alone proves how soft, durable or pill-resistant a finished sock will be.
Check the specification first. Ask for the fiber percentages, yarn count and twist, elastic-fiber content, knitting gauge or structure, and cuff and sole construction for each sample. Separate the cotton yarn description from the composition of the whole sock. Organic, recycled or other certification claims need documents tied to the actual material and order.
Compare samples under the same conditions. Where possible, use the same size, knit construction and care procedure. Record initial hand feel, measurements, appearance after washing and wearer feedback. If pilling, shrinkage or colorfastness matters, agree on a test method and acceptance limit before relying on results. Do not infer a test outcome from the yarn label.
Compare total cost. Request quotes using the same quantity, size mix, packaging and delivery term, and confirm material availability and repeat-order consistency. Combed cotton is not automatically right for every program; carded cotton is not automatically low quality. Decide from the price target, physical samples and written specification together.
For a brand order, use the private-label socks page and OEM process page to prepare sample and quotation questions.
