Jacquard Procion MX fibre-reactive dye Warm Black 454 g jar — deep, washfast colour for cotton & mixed fibres

Jacquard Procion MX Dye #128 Warm Black is a one-pound jar of fibre-reactive, cold-water dye formulated for permanent, washfast colouring of cellulosic fabrics and mixed-fibre projects.

Whether you’re dyeing yardage, handcrafting garments, or experimenting with tie-dye and shibori, this Warm Black shade offers deep, warm-toned blacks with excellent penetration. Procion MX is prized by textile artists and crafters because it chemically bonds to cellulose fibres, producing vivid, lasting colour without the need for prolonged heating—ideal for studio or outdoor dye sessions.

How will Warm Black look on different fabrics?

Warm Black yields rich, slightly brownish-black tones on cellulosic fibres like cotton and linen; results vary by fibre type, fabric weight, and preparation. On lighter natural fibres you’ll get true deep black; on protein fibres or pre-treated materials, the shade can appear muted unless you alter the process.

• Cellulosic fibres (cotton, linen, rayon): deep, even Warm Black.
• Blends: may produce charcoal or smoky blacks depending on fibre ratio.
• Protein fibres (silk, wool): use acid modification for better uptake, colour may be softer.
• Pre-washed/bleached fabrics: truer black with better saturation.

What techniques can I use with Procion MX Warm Black?

Procion MX is versatile for many dyeing methods: tie-dye, immersion, shibori, ice dyeing, batik, and screen printing all work well. Because it activates in cool water, you can set up dye stations outdoors or in a craft space without kettles or stoves.

• Tie-dye & shibori: crisp resist lines and deep blacks when properly prepped.
• Immersion dyeing: even coverage for yardage and garments.
• Batik & screen printing: reliable colorfastness with wax or printing medium compatibility.
• Ice and sprinkle dyeing: dramatic gradients when layered with other colours.

Do I need special equipment or heat to use this dye?

No. Procion MX is a cold-water, fibre-reactive dye, so most applications can be done without boiling water or stovetop equipment. You’ll still need basic supplies—protective gloves, soda ash for fixation on cellulose fibres, squeeze bottles or immersion containers, and thorough rinsing—to achieve optimal results.

• Cold-water activation: work outdoors or in sinks without heating elements.
• Soda ash: recommended for fixing colour to cotton and other cellulosics.
• Tools: bottles, brushes, screens, or buckets depending on technique.
• Rinse and wash: follow thorough washing to remove unfixed dye and improve washfastness.

Who is this for? Jacquard Procion MX Dye #128 Warm Black in a one-pound jar is intended for textile artists, small-batch garment makers, craft studios, educators, and hobbyists who need a substantial quantity of a reliable, deep black dye. It’s suited to people dyeing yardage, large projects, or running frequent workshops, and to anyone who prefers cold-water dye processes for safety and convenience.
