Ludigol is Oxidising agent for the textile industry.
Ludigol helps to prevent any undesired reduction of dyes (e.g. of reactive and disperse dyes) and for reoxidising prints and dyeings produced with vat dyes.
When padded onto discharge grounds (“Ludigolising”) Ludigol prevents the reduction of the ground shade during the printing process and in steaming.
Lugidol Granules are non-dusting.
Usual application rate: 10 g/kg Ludigol Granules

Ludigol is a brand name for m-nitrobenzene sulfonic acid, sodium salt

Ludigol (sodium salt of m-nitrobenzene sulfonic acid) is a mild oxidising agent used in combination with textile dyes to produce intense colour.

You do not need to use Ludigol for room-temperature dyeing.
Its use is to protect fiber reactive dye from being chemically reduced, which is generally considered to be significant only at higher temperatures; its use is optional at room temperature.
Its effect, when it is truly needed, is to make dye colors brighter, improving the yield by preventing their inactivation before they can bind to the fiber.

Since monochlorotriazine dyes (Procion H type dyes) must be steam-set, Ludigol is essential with this class of dye.
Dichlorotriazine (Procion MX type) and monofluorotriazine (Cibacron F, Sabracron F) dyes can be used at room temperature, but they can also be steamed or microwaved.
If heat is used with fiber reactive dyes, Ludigol is definitely recommended, though you can get by without it.
Ludigol is “Essential for achieving very sharp edges on painted fabrics.”

Ludigol is a mild oxidizing agent that helps to prevent dyes from decomposing (being “reduced” – a chemistry teacher question) during fixation, which causes them to be duller. It is a very important ingredient when working with deep shades and is considered to be essential by some when working on silk when painting with Fiber Reactive dyes like Procion MX or Vinyl Suphon Liquid Reactive Dyes and then steaming the work.

Ludigol: Sodium Salt of M-Nitrobenzene Sulfonic Acid, also known as Ludigol .

Ludigol is a mild oxidizing agent that prevents reduction of Reactive Dyes during the curing and setting stage of printing and hand painting.

Ludigol is necessary with H dyes and optional with MX and F dyes.

Ludigol F is a mild oxidizing agent used when steam setting dyes.
Adding Ludigol F to dye encourages more vibrant colors.
Ludigol F is beneficial when working with deep shades or silk.

Ludigol is used in tie dyeing or other direct application dyeing.
Ludigol is generally not used in solid color dyeing.
Reactive type dyes slowly break down once they’re mixed with water, and over time the dye becomes less effective.
Soon the dye solution will lose all effectiveness.
Ludigol is added to the dye to keep the dye from breaking down in the water at higher rate.
Ludigol keeps the dye fresher longer, and allows more dye to react with the fabric, helping the colors to come out brighter.

Ludigol F is a mild oxidizing agent used when steam setting dyes. Adding it to dye encourages more vibrant colors. Ludigol F is beneficial when working with deep shades or silk.

Benzenesulfonic acid, or a derivative thereof, is used as a synthetic intermediate for a number of chemical families of pharmaceuticals, pesticides, dyes, pigments, fluorescent brighteners, and other organic compounds. Commercially, benzenesulfonic acid sodium salt is more common due to high deliquescence of the base material.

3-Nitrobenzenesulfonic Acid Sodium Salt is used as an intermediate for dyes and fluorescent brightening agent.

3-Nitrobenzenesulfonic Acid Sodium Salt is used as an developing agent for electroplating and auxiliary for dying fabrics.
