First of all, sherpa fabric and polar fleece are both types of fleece, sherpa fabric is woven by high-speed warp knitting machine, and polar fleece is woven by circular knitting machine.
Although they all have to be processed by dyeing, brushing, carding, shearing and other processes after they are woven into grey fabrics, polar fleece will have more polar finishing processes than sherpa fabric and ordinary fleece, and the fluff will be more fluffy and dense. It is not easy to lose hair and pilling, the back side is sparse and well-proportioned, and the fluffy elasticity is very good.
However, even though there are many advantages, there are many reasons that have always damaged the wind evaluation of lamb wool and polar fleece, such as the static electricity generated when dry synthetic fibers rub against the skin and clothing, and the lack of wind resistance.
In general, the appearance of smoothness is in order: polar fleece > sherpa fabric
Sherpa fabric fibers have the highest bulkiness and curvature, are long and dense, and feel the most abundant; the fluff of polar fleece is relatively short and uniform, and the weave texture is more obvious;
Usually, the longer the plush fiber and the heavier the fabric, the higher the warmth retention of the clothes. Now there are many long-staple fleece and lamb-like fleece with windproof function.
