Warp Painting on Silk & Wool
using PRO MX Reactive Dyes

Please read directions carefully before starting

Use this method to hand paint on Silk and Wool warps. Always do test samples before working on a large project. For additional information, please visit our website at www.prochemical.com.

Supplies
PRO MX Reactive Dye
Synthrapol
Citric Acid Crystals or white distilled vinegar Urea
PRO Print Paste Mix SH
clear household ammonia

Procedure
1. Make the Acid Soak Solution. Choose one of the methods below. Measure the water from the chart below into a large plastic bucket. Dissolve the Citric Acid Crystals or white distilled vinegar in the water. Add the Synthrapol and stir thoroughly.

Method #1 - Citric Acid Crystals

Method #2 - White Distilled Vinegar

1 gallon (4 liters) 95oF (35oC) water

2 quarts (2 liters) 95oF (35oC) water

11 Tbl (193 gm) Citric Acid Crystals

2 quarts (2 liters) white distilled vinegar

2 tsp (10 ml) Synthrapol

2 tsp (10 ml) Synthrapol

2. Prepare the warp. Stretch the warp on a table covered with plastic. While wearing rubber gloves dip a large clean sponge or foam brush into the acid soak solution and liberally apply it to the warp. DO NOT rinse the warp. You can dye paint the warp while it=s damp from the acid soak solution or let it dry before painting. This acid soak solution can be kept for a couple of weeks at room temperature in a closed container and can be reused to soak more yarn.

3. Prepare the Print Paste. Measure 52 Tbl (55 gm) PRO Print Paste Mix SH into a dry container. Measure 1 cup (250 ml) of warm 110EF (44EC) water into another container. Add measured PRO Print Paste Mix to the water while stirring rapidly. Continue stirring until you obtain a smooth paste. Let paste stand 1 hour or overnight for smoothest results. Unused paste should be kept in a closed container. Store prepared print paste without dye up to six months. Discard if you detect an ammonia smell.

4. Make the Urea Water. Measure 9 Tbl (100 gm) Urea in 1 quart (1 liter) HOT 120oF (49oC) water. Allow to cool to room temperature before using.

5. Make Dye Paint. Measure the PRO MX Reactive dye powder for the shade desired, from the chart below, in a 1 cup (250 ml) container. Thoroughly dissolve the dye powder with just enough Urea Water to make a lump free paste (approximately ¼ cup or 60 ml). Thicken with prepared Print Paste, usually 1 to 2 tsp (5 to 10 ml), then add more Urea Water to make 1 cup (250 ml). Stir until thoroughly mixed. Discard dye paint after 3 to 4 days. If warp does not absorb the dye quickly, then add 3 to 4 drops of Synthrapol to the dye paint.

8 tsp (20 gm)

6. Fix the dye. Allow the warp to "cure" by covering it with plastic for a minimum of 24 hours. Room temperature must be above 70oF (22oC). The warmer the Acure@ temperature, the darker the final color.

7. Rinse the warp thoroughly in a bucket of room temperature 75o to 95oF (24oto 35oC) water. Change the rinse water 3 to 4 times. Then wash with very HOT 140oF (60oC) water adding 2 tsp. (2.5ml) Synthrapol per pound (454 gm) of yarn. Rinse the warp well. If your warp is silk, then stretch it to dry. If the warp is wool, continue through steps 8 and 9.

8. Make the After Soak for Wool. (This is not necessary for silk) Mix 2 Tbl (30 ml) of ammonia in one gallon (4 liters) of room temperature 75o to 95oF (24oC) water. While wearing rubber gloves, swish your wool around in the ammonia water for 3 to 5 minutes. Rinse in room temperature 75o to 95oF (24o to 35oC) water.

9. Neutralize the Wool. Mix 1 tsp (5 ml) of Acetic Acid 56% or 11 tsp (55 ml) white distilled vinegar in 1 gallon (4 liters) of room temperature 75o to 95o (24o to 35oC) water. Wearing rubber gloves, swish the wool around in this vinegar water as the final rinse. Squeeze out the excess water and air dry.
