| Screen Printing with Thickened MX Procion Dye |
| You will need Frame & Screen
of 12” and a set of 16” stretcher bars or a set of 16” & a set of 20” (2 in a set) “Silk Screen”…. Well, not really silk…. Try sheer curtain material (polyester or nylon)….Or a 110 monofilament mesh screen or 10 XX multifilament. (you can order from www.gsdye.com or www.standardscreen. com) Staple Gun – to staple the screen/mesh onto the frame Duct tape – to wrap the edges of the frame and create a “ledge” around the edge of the frame. Fabric
Soda Ash (1/4 cup per 2 quarts of water – note: this is stronger solution than used for immersion dyeing) Pre-soak Prepared For Dyeing fabric for about 15 minutes then hang to dry. If you are not using PFD fabric, pre-wash and dry the fabric, then soak in soda ash solution. Some people like to iron their fabric but once it is treated with soda ash, it will scorch very easily. You will stretch and pin the fabric to a backing before printing so ironing is not necessary but if you decide to try, keep the heat on a very low setting. Sodium Alginate (to 2 cups water + 2 Tablespoons urea + 1-1/2 to 2 Tablespoons Sodium Alginate) – prepare at least 24 hours ahead. It will be lumpy when first mixed but if you stir it every couple of hours, in 24 hours it will be very smooth.
Start with 3 primary colours and black 30 gms dye + 30 gms urea + 1/2 cup water. Combine in a squirt bottle with a lid. This mixture will keep up to several weeks as long as it is not mixed with salt or soda ash. Newsprint – you can tear it or cut it in shapes Masking tape – you can tape it on your screen in grids or shapes “Contact Paper” (adhesive shelf liner) – cut and stick temporary shapes on screen – avoid clear as it is difficult to see what you have cut. Rolls are at a dollar store. Freezer Paper “stencils” cut and pressed on with warm iron (not hot) Leaves, feathers Little scraps of quilt batting or interfacing types of “mask” shapes. Mesh – like an old onion or orange bag, or large needlepoint mesh. Other Equipment 24” squares of Styrofoam insulation (e.g. 2” thick pink or blue) or some kind of base to pin your fabric onto so you can stretch it a bit and keep it from moving and distorting. Squeegee or old credit card or plaster/glue spreader to spread the thickened dye. Poly/plastic drop cloths. You place them under the fabric on top of the Styrofoam base. You then screen print your fabric and when the dye is dry to the touch, you can roll it in the poly to cure for a minimum of 48 hours. Little yogurt type containers to mix dye and alginate. Rubber gloves Old clothes or an apron “T” pins are good or straight pins with a bead-type end (easy to pull out with rubber gloves) Scissors A little cutting mat and exacto knife or box cutter type of knife. Cleanup rags Plastic spoons – about 6 Dishwashing soap and a brush to scrub the screen. Optional: Foam paintbrushes and rubber stamps to play a bit with the thickened dyes. To print: Place a plastic sheet on the Styrofoam then pin pre-treated fabric on about every 6” along the edges. Place your image (designs or leaves, or masking tape or contact paper) on the bottom of the screen and place the screen on your fabric near an edge. Combine about ½ alginate thickener and ½ dye concentrate in a cup and pour some on the duct tape ledge on your screen. With credit card or squeegee, pull thickened dye back and forth across the fabric. Lift the screen carefully and move it to the next space then continue to print fabric. Let the dry to the touch then you can roll it up or place another layer of poly and fabric on top. Pin the next layer of fabric on and do your next print. Curing: Let the fabric cure a minimum of 48 hours at about 70° F or higher: Rinsing: Rinse screen printed fabric a few times in cool water. Put a teaspoon of soap (Synthrapol, T.N.A. Dyers Soap or if you don’t have them, Dawn dishwashing liquid) in a bucket of water and soak the fabric overnight. Rinse until water runs clear. Permanent Screens VS Temporary Screens
permanent but the design is temporary. On the bottom (flat side of the screen), place masking tape or cut shapes from plastic or paper. Once you “ink” the screen, the paper or plastic sticks to the screen and can be carefully lifted and moved along the fabric. You can cut a design out of contact paper with an exacto knife and peel off the backing and stick the design on the screen. It will loosen eventually with the liquid/dye but you can get quite a few prints before it does. The contact paper stencil can be washed and allowed to air dry then stored on waxed paper or freezer paper to use again. Permanent screens are intended to be used many times. They can be made with a photo/light sensitive exposure on special film or you can order them from custom/commercial suppliers. They are used with a slightly different frame than what we are using for temporary screens. There is often a slot for the stencil to slide in. |
