Polyester can be made from plastics that are marked with the recycle numbers 2, 4, or 1, so the same dyes that are used for polyester would probably be your best bet for any of these plastics. Acrylics can be dyed not only with disperse dyes , which are the best and safest choice for home use; they can also be dyed with dyes from a class called Basic Dyes , or cationic dyes.
Acrylic plastics may not be not quite the same as the acrylonitrile used in acrylic fibers, so it's possible not all acrylic plastics will dye equally well with basic dyes. Basic dyes are unpleasant to work with, unless you have a properly safety-equipped laboratory; when used at home, they tend to badly stain everything they come in contact with, and some of them are possible carcinogens which I do not like to recommend for use by people who are not trained in laboratory safety procedures.
See " Dyeing Acrylic with Basic Dye ". There are other plastics which simply cannot be dyed at home. Some plastics must be dyed while they are still in the liquid form. For example, polypropylene , marked with the recycle logo number 5, is used to make water bottles and also to make some performance sports clothing and stain-resistant carpeting and upholstery material, such as Herculon or Olefin. No matter what color your polypropylene object may be, you will not be able to dye it.
It repels water sufficiently that it is unlikely you will even be able to paint a polypropylene material, unless you use a a special paint called Krylon Fusion for Plastics. Before tackling any large or expensive project, be sure to do a small-scale test of trying to dye your plastic material with the recommended dye, to see how well your results come out. If you do not know what material your plastic is made of, you might try dyeing it as though it is nylon, first, since that is the easiest sort of plastic to dye, and proceed to try other dyes for other types of plastics if that does not work.
You also want to make sure that you clean your parts very well before their bath. Any dirt, grime or oil can cause discoloration. This is the Tamiya Clodbuster that I use as a retro monster truck racer. It looks good here, but after a season of racing it got beat up pretty good. I wanted to change to a new aftermarket chassis and color scheme. Time to break out the dye! With that said, I wrapped up the kitchen experiment and decided to change our strategy by heading out to the local fabric store to purchase some synthetic fiber dye.
Rit Dye More is blended with synthetic pigments and contains a type of dye called disperse dye. So I took a more aggressive approach this time around and mixed acetone with the newly-purchased Rit formula. I began stage 3 by filling a small container with water heated to degrees Fahrenheit. Because I used acetone as an activator for this experiment, I moved the procedure into a well-ventilated area. Pure acetone is best bought at any hardware store — larger quantities can be purchased inexpensively, and it will last much longer than a small bottle of nail polish remover bought at a retail store.
Pro tip: never add acetone to a hot water dye. Acetone has a lower boiling point than water and will explode on contact, similar to throwing water into a pot of boiling oil. We learned this the hard way and nearly peed in our pants when the liquids literally jumped out of the container.
There is no concrete setting for how much acetone it takes to dye any plastic — this part of the process is trial and error.
You need to add acetone until the part accepts the dye, but at the same time be sure that the plastic does not have a serious reaction to the acetone, which can cause it to melt. Acetone allows the dye to seep into the pores of the material. After agitating the parts in the new Dye More solution and acetone mixture for 15 minutes, the parts came out noticeably blacker in color. The parts spent a few more minutes in the chemical bath before they were removed and washed in distilled water.
Here are the newly dyed sun visor parts fresh out of the mixture. Other than the scuff marks left from the sand paper, both visor clips look like they were molded in black straight from the factory — and the best part was not a hint of white upon final inspection! Front Street Media. This helps to remove any finishes that may interfere with dye absorption. No, I'm sorry.
Polypropylene is a special case. It's simply impossible to dye an item that is made of polypropylene. Polypropylene also known under the brand names Herculon and Olefin is colored by the addition of pigments while still in liquid form, before it is extruded into a fiber.
It comes in a variety of colors that you can mix to get an infinite amount of colors. The All-Purpose Rit Dye also works on rayon and nylon, along with cotton , linen, silk, and wool. Vinyl is dyed with spray paint, so the job is more like painting furniture than dying fabric.
It takes time and care, but dying your vinyl upholstery or interior is something you can easily do at home. I can 't give you a definitive answer for every plastic , but most plastics can be safely treated with a diluted solution of household bleach no more than a tablespoon of bleach to a cup of water without ill effect.
Don't let it sit too long and rinse it thoroughly with water. Nylon turns out to be great for paint and varnish because it is a highly polar polymer. Unsurprisingly, paints specifically for plastics usually end up working the best for 3D printed parts. Usually Rust-Oleum or Krylon have a wide variety in color and application of paints that work on 3D printed plastics. The safest way to dye acrylic at home is to use a kind of dye called disperse dye , such as iDye Poly.
It's simple to use: heat water in a large cooking pot, dissolve the disperse dye in it, add the acrylic clothing or yarn that you want to dye , then heat it to a simmer, stirring constantly. What can I use to dye plastic? Category: hobbies and interests painting. Vinegar is also known as acetic acid, which helps the dye to penetrate the surface of the plastic more effectively. Give the formula a couple stirs before adding in dishwashing detergent. Can you dye black plastic?
