Message: hi, i have recently purchased a cardigan in a charity shop which id like to dye, it is 57% acrylic, 30% nylon and 13% mohair, it is baby pink in colour and id like it to be dark brown, how could i go about doing this or will it not work?

The problem is that you cannot reasonably dye the 57% of the fiber that is acrylic. The only dyes that will dye acrylic to a dark shade are a type of dye called basic dye, which unfortunately is too toxic and/or carcinogenic to be truly suitable for use in your home. You'd certainly have to buy a large non-aluminum cooking pot to use with dye only, since it is very bad to use a cooking pot for food after using it with this dye, but the cooking pot would cost more than a new sweater.

You can dye both the nylon and the mohair with a type of dye called acid dye, but if you do, only 43% of the fiber will take the dark brown color. The acrylic will stay baby pink. Here is a link to one of the few acid dyeing recipes which do not require high water temperatures that will shrink the mohair.
