How to identify cotton socks?


During the inspection of socks, we sometimes identify whether the socks are pure cotton at the inspection site according to the requirements of the client. Generally, we have the following four methods for identification:
Touch - Pure cotton fabric feels full and thick, and looks the same thickness of fabric, pure cotton feels stronger and more resilient.
Observation - pure cotton fabric is not reflective, with two hands to flatten the fabric and add a certain tension, the fabric and the body down at a 45 degree Angle, to the light source to see if there is a bright light, if there is, it contains chemical fiber material.
Tips: This requires a certain amount of experience, because generally, nylon, spandex, polyester, nylon and other fibers are added to the bottom yarn of pure cotton socks to enhance the elasticity of pure cotton socks. However, acrylic and other fibers are added less, and cotton components are more. Such socks have soft hand feel, good moisture absorption and comfortable wearing.
Kneading -- cotton kneading after obvious folds, fold the fabric in half with nail scraping, unfolded after a clear fold line, and chemical fiber fabric kneading after there is no fold.
Burning -- cotton fiber near the flame will not melt or shorten, contact fire immediately burning, burning when the smell of burning paper, after burning out into a fine and soft gray, black and white flocculent gray, will not produce hard.
Tips: The correct way to determine if a sock is pure cotton is to identify the veil thread, which is the thread on the front of the sock (except for the decorative pattern), rather than pick up a random pile of thread inside the sock and burn it together. That, along with the bottom yarn, will burn into a lump.
Cotton socks will burn quickly when lit and last for some time. Cotton has very little powder ash and no particles or lumps when pinched by hand. The burnt ashes of synthetic socks condense into particles or clumps. And pure cotton socks for high carbon plant fiber, after burning issued paper-like smell, and chemical fiber burning smell is very different.
