Abstract
This invention relates to a method for making polyester fabric treated with a CBD powder to provide a novel CBD finish on the polyester fabric. The polyester fabric is treated with a CBD powder to provide a novel finish. The treatment process includes a washing step, wherein the treating CBD water is added to a water channel before the finishing step. Then, the polyester fabric is passed through the water channel having the treating CBD water in the ratio of 1:1000, which is one gram of CBD powder to each 1000 grams of water. The flow rate of the treating CBD water has a ratio of 5:1000, which adds 5 grams of CBD powder to each 1000 grams of water in order to apply the correct treatment of CBD water. In addition, the polyester fabric moves at a speed of approximately 20 meters per minute through the water channel, and the bathing treatment has a normal temperature of 30-35° C. The maximum temperature of the drying machine is 220° C., but has a preferred range of 170-220° C. In addition, the polyester fabric passes through the drying machine at a speed of 20 meters per minute.
