It has a luster and sheen that is unmatched. In Double Mercerization the knitted fabric undergoes a second Mercerization process to remove these. Double mercerized fabric feels so soft and smooth its look and feel can easily be mistaken for silk. It passes through so quickly that the yarn itself doesn't burn but the millions of fuzzies and slubs on the yarn are eliminated instantly. Mercerization also cleans the yarn and gives it a strong affinity for dye. While normal cotton yarn has no clarity or depth to it's color, Mercerized yarn accepts the dye much better and the colors come out deeper, sharper and have a very clean look.

This makes the yarn stronger. Single Mercerization is a huge step up from the quality of regular cotton shirts but Double Mercerization takes it even a step further. Since there is no fuzz on the yarn, it is held together better and can no longer unravel by itself. The fabric now looks and feels ten times better.During the knitting process some fuzzies will ultimately resurface. The fabric is placed in a chemical bath using caustic soda to once again remove any additional fuzzies or slubs and is then washed clean.. This makes the fabric even stronger Tpu Combined Fabric and makes it look and feel even better. The yarn is also less prone to shrinking because the mercerization process literally pre-shrinks the fabric.Single Mercerization is a process in which the yarn used to make a shirt is run through the middle of an open flame at a very high speed.
