No, not "ponies". (And get your mind out of the gutter, too.)
Poonies (or punis) are cotton prepared for spinning by carding it and then rolling it tightly into thin cigar shapes. I've been meaning for a while to experiment with dyeing some prior to spinning. I've seen some commercially dyed poonies and they look nice but the prices are just too high. So tonight I took a 100g bundle of Indian poonies and divided them into smaller groups, loosely tying each with pieces of yarn. Then I soaked them in a solution of warm water and sodium carbonate (washing soda.)
I used Procion MX fiber reactive dyes (bright yellow and navy blue) to prepare two small cups of stock solution (50 ml of warm water and about 3 ml of dye powder for each color.)
When the poonies were soaked through, I squeezed them out gently and set them aside while I prepared the first color bath by adding the yellow stock solution to 1.5l of warm water into which 10g of ordinary salt and 5g of the washing soda had been dissolved. The pale yellow stock solution blossomed into a brilliant orange yellow. I stood the poonies on end in this solution, sloshing them up and down gently then letting them rest for about 20 minutes with one end in the dye, and the other in the air, so that the dye only soaked up through about 2/3 of their length, leaving the top ends still natural colored.
When the yellow seemed intense enough, I rinsed them in running water until the water ran clear and squeezed them gently again.
Then I prepared the blue dye solution from the same proportions as the yellow, and repeated the process, but dipped the undyed ends into the blue dye. The end result after rinsing and washing out with mild detergent was poonies that varied in color from bright yellow at one end through green and then to sea blue with white flecks at the other end. This was more or less what I'd hoped for. Now if they dry out without being so matted that I can't spin them, I will be able to make cotton yarn in "bright beach" colors: yellow sun, green foliage, natural creamy sand and foam, and shades of blue for water and sky. I'll photograph the dyed poonies tomorrow when they've dried a bit.
