Combed cotton refers to the yarn produced by using high-quality cotton fibers as raw materials and increasing the combing process compared to conventional combing during spinning. This involves smoothing out the cotton fibers, removing impurities and short fibers from the fibers, leaving only long fibers. Therefore, the yarn it spins is of good quality, with a clean surface and a soft feel. The price is moderate. BAIJIAN provides authoritative and effective testing reports, mainly covering food, agricultural products, environmental soil, environmental protection, industry standard training, retail services, etc., providing convenient testing services for you. If you need it, you can contact us. Testing items include quality, content, tension, count, defects, breakage (single yarn breaking strength and elongation at break), density (linear density, bulk density), strength, moisture content, oil content, twist, color fastness, etc p>
