How To Make Saffron Dye
Name: Donna
Message: Hi- I am collecting walnuts, goldenrod, sassafras and poke weed to use on 100% cotton (white and natural) petite canvas numberless. The handles are polyester so they will probably non have the dye. We are going to sell these to raise funds for our local animal protection agency. What is the best way to obtain the colors from these natural materials and what is the all-time style to fix the color into the material. I was told 2 different things- apply urea or utilize soda ash. What practice you recommend? Thanks for you lot help !!!
—ADVERTISEMENTS—
Please don't sell annihilation you make until subsequently you lot take tested it for washfastness! Brand admittedly certain certain that dye does non rub off when dry, nor drain when moisture, before selling anything. Every bit a general rule, natural dyeing requires a lot of experience; the application of natural dyes is much more demanding and labor-intensive than that of constructed dyes. A beginner'southward first experiments with natural dyeing do not unremarkably result in professional person-quality goods that are suitable for sale.
Neither urea nor soda ash will fix your natural dye! Urea is a humectant used to retain wet during reactions of synthetic dyes. Soda ash, which is the main ingredient in washing soda, merely increases the pH, which is essential for using synthetic fiber reactive dyes on cotton, but will non assist in setting natural dyes. Whoever told you to use urea or soda ash to fix natural dyes is non an expert in the dyeing process.
In order to gear up natural dyes in your cotton, you must pre-mordant information technology. I recommend that yous acquire a copy of Dagmar Klos'south book, The Dyer'due south Companion, which contains detailed recipes for mordanting cotton and other fibers. The Art and Arts and crafts of Natural Dyeing, past J.N. Liles, contains recipes for mordanting cotton, as well, but it is not as piece of cake for a beginning dyer to empathise. Use the alum-tannin-alum method of mordanting for best results. Boil your (prewashed) cotton bags for the indicated fourth dimension in the indicated forcefulness of alum. Next, repeat the procedure with tannin. For your tertiary step, repeat the alum treatment over again. Only after this three-step premordanting process has been completed can you apply the dyestuffs. Yous will need to find a expert recipe for dyeing cotton wool with each of your natural dyes, as well. Most natural dyeing books comprise recipes just for wool, which is vastly easier to dye than cotton; wool recipes cannot exist used for cotton. As a full general dominion, you will need one to two pounds of natural dyestuff for every pound of fabric, and, in most cases, you will need to boil or simmer the dyestuff for some fourth dimension. Weigh your canvas numberless so that you have an idea of how much you will need. If your stack of bags weighs v pounds, in general you should collect ten to 15 pounds of dyestuff to utilise on them. It is simply dye extracts and constructed dyes that can be used in smaller quantities than the weight of any fabric you are planning to dye.
Walnuts are probably the all-time and strongest of the dyes that y'all propose to apply. Because of the tannins in the walnuts, you can omit the tannin stride in mordanting cotton fiber to be dyed with walnuts, though the alum is still important. I accept seen recipes that call for grinding the hulls of green walnuts and letting them rot for a week earlier using them in dyeing. Lile'due south book The Fine art and Craft of Natural Dyeing contains recipes for dyeing cotton and linen with walnuts, but warns that pokeberry gives but non-lightfast results, and that simply on wool, not cotton. This book includes a recipe that says that a half-pound of goldenrod flowers is sufficient for i pound of cotton, mordanted with alum/tannin/alum.
Interestingly, when my son used turmeric to dye various fibers for a science fair project, the polyester which had been mordanted with alum did have the dye, a squeamish yellow. (He boiled the fiber in the alum so in the turmeric, I recall for half an hour each.) If you try turmeric, which is a rather easy-to-utilize natural dye—only a few spoonfuls are needed—be sure to label your goods with a alarm that the dye is not lightfast and will fade with time. Dissimilar nearly other natural dyes, turmeric can dye unmordanted cotton wool, which makes for a much simpler procedure.
The thought of natural dyes is very appealing, just, equally you can see, this is no beginner's project that you have undertaken. You lot should obtain recipes in a trusted dyeing volume in order to have any hope of success, and yous volition need to allow enough of time for trial and fault as y'all learn to correctly use mordants and natural dyes.
