Da algo de color al poliester pero no merece la pena

Lo he utilizado para renovar el rojo de una antigua chaqueta slam de mi marido que había perdido mucho color y estaba muy desgastada. Lo he hecho en la lavadora según las instrucciones (eso sí, las busqué en la web. La cual puedes poner en castellano). Ha quedado PERFECTA, color totalmente uniforme. Acabo de comprar otro bote igual esta vez para otra slam, la de mi hijo. Lo recomiendo. Ah! Y al terminar el proceso a la lavadora le hice lavado con lejía y un poco de mistol/fairi y está perfecta, ni rastro. Lo que parecía que había tenido la goma de la puerta, desapareció.

I used this to brighten up some red clothes that had gone to almost pink. The red color is not quite the "true red" that I would have liked, but it did an OK job. I chose the washing machine method, followed by a cycle of color stay fixatative. The HE washing machine needed some attentive cleanup in the soap compartment, but otherwise did the job. To be extra safe, I washed a few loads of "sacrificial" towels. I followed the Rit YouTube videos for the instructions. I opted for the added salt water for effective dying. The combination of the dye and fixatative seems to have a good longevity. The clothes have been washed several times with no sign of fading.

Ottimo colorante a 70^. Usare un recipiente sufficientemente grande da contenere tutto l'oggetto che si vuole colorare per poterlo girare altrimenti la colorazione non diventa uniforme

Good product and easy to use

My job requires its employees to wear red tops, and I didn't want to spend a lot of money for a red sweatshirt, so I bought this to dye a heather grey hoodie I already had.Dying the garment was really fun. I followed the directions for the material I had and did the dying in the kitchen sink. It was easy to do, but I would definitely recommend wearing gloves. I used tongs to move the hoodie in the water so it would dye evenly, but you have to rinse the garment in cold water until the water runs clear, and that was too hard to do with the tongs. My hands ended up being red for two days. Oops.The problem that I have is that the dye isn't really 'set'. You don't get dying instructions with the dye, you have to go to RIT's website for instructions. In the "Dye 101" section it makes no mention of future washing instructions. In the "Tips for Successful Dying" section, the NINETEENTH "tip" is: "CARING FOR DYED ITEMS. For the first two or three times, wash your dyed item by itself in cool water with a small amount of non-bleaching detergent. Always wash your dyed clothing with similar colors in cool water with mild detergent. Dry cleaning silks and special fabrics is recommended."That would have been helpful to know - and yes, in retrospect I'm kicking myself, because maybe it's obvious now, but I managed to dye a whole load of colored clothes pink. My khaki pants are a disconcerting shade of salmon now...and the hoodie has faded from red to some very weird color that falls in the red family, but really isn't red at all. :(All that said, I'm considering buying another bottle of red and retrying. First, starting with a light red jacket and using a full bottle might get me a darker, truer red. I'd add some boiling water to my mix and wash it alone forever. But $4 for another bottle of dye is better than $30 for a hoodie that I'd only wear to work.
