Jacquard Acid Dye - Jet Black - 1 Lb Net Wt - Brilliant Colorfast

In this review of Jacquard Acid Dye in Jet Black, the bottom line is simple: this is a specialist dye for makers who need deep, consistent black on protein fibers. The reviewer found it especially useful for silk, wool, feathers and nylons where a highly concentrated powdered formula produces level, uniform color during immersion dyeing. If your projects demand long-lasting, intense color and professional consistency, this Jacquard dye delivers that reliable result more often than not.

Key Features

• Formulated for protein fibers: Designed specifically for silk, wool, feathers and nylons, it produces rich, even blacks on delicate fibers when used with an acid like white vinegar or citric acid.
• Highly concentrated powder: The powdered, hot water formula allows precise control of shade and is economical for dyeing larger batches like yarn or fabric.
• Consistent immersion results: The dye yields level, uniform color during immersion dyeing, which is useful when matching skeins or pieces across sessions.
• Colorfastness: Jacquard's formula resists fading and bleeding in many cases, so finished items retain their brilliance through normal washing when set properly.
• Multipurpose application: Suitable for yarn dyeing, silk projects, wool dye kits, feather art, and techniques like direct painting and steam setting for creative uses.

Who It's For

This dye is aimed at fiber artists, professional dyers and serious hobbyists who work primarily with protein-based fibers and require a dependable jet black that holds up to handling and washing when properly fixed. It's especially good for those dyeing silk garments, wool yarns for garments or accessories, and craft feathers where deep black and uniform coverage are priorities.

Casual crafters who only dye small cotton or synthetic blends should look elsewhere, as this acid dye is not formulated for plant fibers or acrylics without special mordants or different chemistry. Beginners will get results, but should follow immersion and acid addition instructions to avoid uneven shades or washout.

Frequently Asked Questions

Is this dye suitable for cotton or linen?
No. This acid dye is formulated for protein fibers like silk and wool; plant fibers require different dye types or mordants.

How is the dye fixed?
Fixation is achieved with an acid such as white vinegar or citric acid added to the hot dye bath and following recommended immersion and rinse procedures.

Will the black bleed in the wash?
When properly set and rinsed, the dye shows good colorfastness, but untested or improperly fixed items can experience some bleeding, so pre-testing is recommended.
