But players usually swap it with their opponents at a full-time RIP George Floyd Black Lives Matter I can’t breathe shirt. What you are seeing means that the excess blue dye particles were not rinsed out completely. It is a fault in the creation of the cloth. When the cloth is dyed some dye particles stick to the cloth and stay there. The other dye particles don’t stick and should be rinsed away before the cloth is made into a shirt. The dye that sticks will stay stuck more or less forever, fading only very slowly. It takes many many liters of water to properly rinse dyed cotton. It’s wasteful of water and it’s very common to sell under-rinsed fabric. The fabric looks brighter than it really is due to the loose dye. I am guessing there is blue cloth sewed onto white cloth? Wash your shirt by hand in very cold hot water, separately.
If you can get hold of dyer’s soap, that will help mop up the excess loose dye before it can resettle on the white part of the shirt RIP George Floyd Black Lives Matter I can’t breathe shirt. We have a soap called Synthrapol which is designed for this purpose. Maybe you can find something like that? Probably it will be difficult. Synthrapol is recommended with hot water. Whichever soap you decide to try, you need to keep washing and rinsing until the water runs clear, no matter how long that takes. The manufacturer should have done this for you before sewing it to something white. Yes, it will be faded, but the color was not fast to start with. Better to wash it away completely than to have it move to the white on its own later. Swish, squeeze, and rinse. Swish, squeeze, and rinse. Don’t twist or wring the fabric or you will ruin the shape of the shirt.
