She's talking about dyeing cotton. If you're gonna come in hot like some kind of expert, read the OP and follow the thread. |
Incorrect. Here's a blog (not mine) showing tea dyeing poly well beyond "off white" https://www.sewhistorically.com/black-tea-dye-on-polyester-lace-and-fabric/ and here's the science of how/why it works: https://pmc.ncbi.nlm.nih.gov/articles/PMC10948525/ Tannins can achieve lightfast and washfast results on cottons just fine, and can penetrate poly perfectly well. If you're that worried about it, buy a higher-quality shirt. There's plenty of cotton thread in the world, and higher-quality garments aren't usually made with poly unless it's a specific feature. |
No, you don't need scalding water to dye cotton. Stick to silks, because the rest of this sounds like you asked AI and got the results you deserved.

Sure. But maybe people could also consider wasting less, buying less, and learning how to adjust what they have to suit their needs and wants. Your gran probably knew how to solve this problem, and you don't because there's an entire industry that profits from your ignorance. |
You don't appeae to have much understanding about fabric dyes or fiber content I dye fabric weekly. Her threads are going to be different colors than her cotton fabric. Cotton and poly do not take dye in the same way. The two fibers require different temperatures, techniques, dyes, acidity, and amount of time in the dye bath to achieve similar color saturation. |
You do not know what you are talking about. I do this professionally, for over 3 decades, and am very skilled and educated in dyeing technique. If she is dyeing a new, unwashed cotton garment, it will shrink in the dye bath. That part is not rocket science and to claim otherwise is just foolish. And unless she is doing a summer camp tie dye project where uneven color is just fine, the dye wash needs to be hot, preferably a low simmer becsuse the heat binds the dye to the fabric fiber. Again, this is very, very basic stuff. |
You don't sound like a professional at all. Maybe you should update your dye practices. Start here: https://prociondye.com/ When you're finished, go back and look at the research articles cited above. Tannic dyes do not require boiling, and an actual professional would know that. Your (seemingly limited) experience dyeing silks doesn't translate to cotton. Silks are protein fibers and take an entirely different class of dyes. Any pro knows this, but feel free to continue showcasing your arrogance and your whole ass. |

Good point. It also won't necessarily dye evenly. It will appear "antiqued" but will not give a nice, even cream color. |
I agree. It takes some finesse to get an even dye finish when you are dyeing finished clothing pieces. |
If she wants cream, she needs yellow pigments not brown. That being said, the other poster is correct. It is simpler to buy a new shirt rather than trying to tint an existing shirt. |
Are you wealthy? Ralph Lauren has some beautiful options, but they are $$$$$ |
Bloomingdales has a few too, that are not quite es expensive as good old Ralph. |
