Oksigol RS granül (Ludigol)
Dispers ve reaktif boyanın redüksiyonunu önleyen,
vat boyanın oksidasyonunu sağlayan madde

 

Kimyasal Yapısı : MNBS ,Resist salt

Teknik Bilgiler

Görünüşü : Açık sarı- Ekru renkli granül

Çözünürlük : Su ile düşük sıcaklıkta bile her oranda çözülür, Baskı patlarına ilavesinde kısa süreli karıştırmalar yeterlidir.

pH Aralığı :6 - 6,5 %1'lik çözeltide

Özellikleri :

- Dispers ve reaktif boyanın; sıcaklık, buhar, boyama süresi, sıcak hava gibi uygun olmayan veya değişken şartlardan kaynaklanan redüksiyonunu önler.

- Polyester aşındırma baskıda polyester üzerindeki boyanın korunması için redoks tamponu olarak kullanılır.

-Aşındırma baskıda redüksiyon yardımcılarından dolayı aşınan yüzeydeki renk değişimi, baskıdan önce boyanmış kumaşa Oksigol RS verilerek önlenebilir.

- Özellikle viskon ve viskon türevlerinin baskısında ve boyamasında; viskon elyafın üretiminden kaynaklanan ve yeterli olmayan ön işlem ile elyaftan uzaklaştırılamayan redüktif potansiyeli yüksek kükürt bileşiklerinin boyarmaddeyi indirgemesini önler.

- Vat aşındırma baskıda; baskının yapılacağı boyalı kumaşın, baskı öncesi Oksigol RS ile fularlanması, baskı ve buharlama sırasında ortaya çıkabilecek stampa ve sürtme sorunlarını en aza indirir.

- Oksigol RS; tozuşmayan formda granül bir ürün olduğu için çalışan ve çalışılan ortamın sağlığı açısından sorunsuz bir üründür.

- Çektirme ve kontinü sistemlerine uygundur.

 

Uygulama :

 

Baskı İçin Oksigol RS Kullanım Miktarları:

· Reaktif ve dispers baskıda redüksiyon önleyici olarak 10 g/l

· Aşındırma baskıda redüksiyon yardımcılarından dolayı renk değişimini önlemek için baskıdan önce boyanmış kumaşa fularda 8-10 g/l

· Vat baskıda oksidasyon maddesi olarak 60-70 oC, 10-15 g/l

· Vat boyalı ve baskılı kumaşlarda mukavemeti arttırmak için 5-20g/kg Oksigol RS kullanılır.

Boyama İçin Oksigol RS Kullanım Miktarları :

· Reaktif boyamada redüksiyonu önlemek için: 1-2 g/l Oksigol RS kullanılır.

· Vat boyamada oksidasyon :

Taze banyo ile oksidasyon : Boyama sonunda banyo boşaltılır. Koyu bir renk ise durulama yapılarak, açık renk ise durulama yapılmadan yeni banyo alınır. Oksigol RS ile 60 oC'de oksidasyon yapılır. Rengin derinliğine göre 1-8 g/l arasında Oksigol RS kullanılır. Peroksit kullanılarak yapılan oksidasyon ile aynı renk tonu elde edilir.

Seyreltilmiş banyo ile oksidasyon : Oksidasyon için ikinci yöntem ise boyama sonunda banyonun bir kısmı boşaltılarak taze su alınır. 2-4 g/l Oksigol RS ilave edilerek 60-70 oC, 10-20 dakika oksidasyon yapılır. Bu yöntem ile zaman ve su tasarrufu sağlanır.

Oksidasyon öncesinde kumaş üzerinde kalan hidrosülfit miktarının minumum olmasına dikkat etmek gerekir. Bu durumda, boya tamamen küplenmiş durumdadır.

 

Oksigol RS ile seyreltilmiş banyoda yapılan oksidasyondaki renk tonu ile vat boyanın peroksit ile oksidasyonu sonu oluşan renk tonu aynıdır. Fark olduğu durumlarda reçete kontrolü yapılmalıdır.

US2011014121 MODULATORS OF CXCR7 2011-01-20 Ludigol is a brand name for m-nitrobenzene sulfonic acid, sodium salt. (Thanks to Doug Wilson's wonderful Dyes and Dyeing Glossary for this definition.) It is sold by PRO Chemical & Dye as Chem Flakes, as Ludigal F by Dharma Trading Company, and and as Ludigol F by Jacquard Products (Rupert Gibbon & Spider).

 

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, PROchem says that Ludigol is essential with this class of dye. Dichlorotriazine (Procion MX type) and monofluorotriazine (Cibacron F, sold by PROchem as 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. G&S Dye says that Ludigol is "Essential for achieving very sharp edges on painted fabrics."

The only time I've ever used Ludigol myself was after someone at one of the smaller dyehouses told me it could be used as a preservative so that Procion MX would stay 'good' in solution longer, which would mean that somehow it would quit reacting with the water molecules to become inactivated by hydrolysis. I immediately bought some, and ran some tests of my own. To my sorrow, it turned out to be completely untrue. Ludigol did not extend the lifespan of Procion MX in solution; if anything, it slightly accelerated the breakdown. To keep Procion MX dyes in solution for up to a few weeks, you can only refrigerate the dye mixtures, but for much use of stock solutions (which are handy for avoiding exposure to potentially allergenic dye powder), you need to switch to less reactive dyes, such as Cibacron F (Sabracron F), Drimarene K, or Remazol (vinyl sulfone) dyes, or steam-set dyes such as Procion H.

I've been thinking I should use Ludigol when microwaving Procion MX type dyes, ever since hearing of Phil Jones's great results, but, as of this writing, I've never gotten around to it. My results have been satisfactory without it.

PROchem, interestingly, suggests using Ludigol in low water immersion dyeing if you live in a smoggy environment. I don't know which pollutant they are concerned about, in this case, nor how significant an impact it may have.

Jacquard Products recommends using 1 US tablespoon (15 ml) per quart (1 liter) of dye solution. PROchem's LWI recipe calls for 1 level teaspoon (5 ml or 2 grams) of Ludigol per quart (liter).

Ludigol F Instructions

 

GENERAL INFORMATION AND USE
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.

 

Add 1 Tbs. per quart of dye/chemical water mixture.

 

Urea, Ludigol and Water Softener
Urea is used in tie dyeing, or other direct application dyeing. It is generally not used in solid color dyeing. Moisture is an important component of the chemical reaction process with these dyes. Urea helps draw moisture to the chemical reaction, helping the dye penetrate the fabric. Urea also helps large amounts of dye dissolve in small amounts of water. We estimate that one pound of Urea will prepare enough chemical water to tie-dye about 16 to 18 t-shirts. 5 pounds will therefore prepare enough for about 80 shirts. Ludigol is used in tie dyeing or other direct application dyeing. It 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. We estimate that two ounces of ludigol will prepare enough chemical water to tie-dye about 60 t-shirts. Therefore, an eight ounce bag will prepare enough for around 240 t-shirts. Water Softener is used in both tie-dye and solid color dyeing. Dyes simply work better in soft water. One eight ounce bag of water softener will tie dye approximately 160 t-shirts.Product Description

Ludigol: Sodium Salt of M-Nitrobenzene Sulfonic Acid, also known as Ludigol . A mild oxidizing agent that prevents reduction of Reactive Dyes during the curing and setting stage of printing and hand painting. It is necessary with H dyes and optional with MX and F dyes.Ludigol
Useful when hand painting with Procion MX: helps prevent dyes from decomposing during fixation - important ingredient when working with deep shades of colour; essential when working on silk. Would need to finish with steam or microwave.Ludigol F
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.JACQUARD LUDIGOL F - DYE BATH OXIDISING ADDITIVE - FOR NATURAL FABRICS - CHOOSE SIZELudigol is also known as resist salt or Matexil PAL. Add to Procion MX fibre reactive dyes as a colour enhancer when steam setting for brightest, most vibrant colour results as there is a tendency for procion dyes to go weaker and duller because of the reducing action caused by the heat from steam. Adding a small quantity to print paste will help prevent loss of colour. Use 30ml per litre of water and 3ml per 100ml in printing paste.
