What’s your favorite color?

This recent addition to our collection is Diazo dyestuffs on rayon discharged with Rongalite C. It’s one folded sheet that pulls out to reveal 6 pages with dye samples of gorgeous colors. While this dye sample sheet is only from approximately 1930-1950, it’s amazing that these colors held up so well!

Reductive Discharge Ink-Jet Printing of Pre-Dyed Textile Fabrics

Abstract

Bleached cotton fabrics have been dyed with Remazol (sulphatoethylsulphone (Dystar)), Procion MX (dichloro-s-triazine (Dystar)) and Procion HE (bis-monochloro-s-triazine (Dystar)) reactive dyes to yield suitable coloured backgrounds for subsequent reductive discharge ink-jet printing. Silk fabric has also been dyed with an acid dye to provide an alternative substrate for subsequent discharge printing. Suitable white discharge inks have been formulated using either Decrolin (zinc sulphoxylate formaldehyde (BASF)) or Rongalit C (sodium sulphoxylate formaldehyde (BASF)), whilst coloured illuminating inks have been formulated using either vat or solubilised vat dyes. Inks containing both a discharging agent and an illuminating colour have also been developed. A process has been developed in which the free aromatic amine groups present in the discharged areas of white prints are diazotised and coupled to a suitable aromatic amine, phenol or naphthol derivative to provide an illuminated print

Introduction

Discharge printing is a technique that is widely used in the textile industry and involves the local discharge of dye on a ground shade using a suitable chemical in a print paste [1]. Such discharge agents include oxidants, such as per-acids, or reductants, such as sodium or zinc sulphoxylate formaldehyde, the latter being more usually used. Coloured prints are also desired and so illuminated discharge pastes that contain a discharge agent and either an oxidation or reduction-resistant dye, such as a vat or sulphur dye, are extremely important.

Conclusion

Discharge inks containing either Decrolin or Rongalit C can be prepared and readily ink-jet printed on pre-dyed background fabrics using an office ink-jet printer. The printed fabrics can then be steamed to produce white images on a coloured background. The images achieved using Decrolin appeared whiter than the corresponding images obtained using Rongalit C; both sets of prints gradually yellowing on storage. The cartridges containing the discharge agents were repeatedly used over several weeks without any loss of performance or evidence of print head blocking. Coloured discharge inks can be formulated which contain both a discharge agent and a solubilised or leuco vat dye; such inks enabling the production of coloured images on a coloured background. Rongalit C appeared to be the most suitable discharge agent as it enables water soluble inks to be readily formulated. If Decrolin was added to the coloured ink formulation, then the zinc ions present either caused the immediate precipitation of the vat dye present or resulted in an ink of short storage stability. As an alternative to vat dyes, solubilised Sulphur dyes may also be used as illuminating colors in discharge ink formulations. Illuminated images may also be achieved via a two-step process in which the background dye is initially printed with a white discharge ink formulation and then over-printed with an ink formulation containing either a solubilised vat or Sulphur dye. Such a process would enable both Decrolin and Rongalit C to be present in the discharge ink formulation.

Ink-jet cartridges containing solubilised vat dyes were found to suffer from print head blockage problems after several days due to the dye on the print head surface gradually oxidizing back to its water insoluble form on air exposure. Illuminated prints achieved using a colored discharge formulation exhibited haloing effects in which a white discharged area was found to encircle the colored area. By pre-treatment of the fabric with a suitable thickening agent, such effects could be eliminated and an improvement in print definition and clarity achieved. Single colored prints under a dark background of a different colour can be produced by diazotising the covalently bound primary aromatic residues present in the discharge area and coupling them to a suitable aromatic amine, phenol or naphthol derivative. In the case of solubilised vat dyes, ISO 3 wash-fastness tests carried out on illuminated discharge prints indicated that some loss of dye from the illuminated area had occurred; the tests also indicating that significant staining of adjacent nylon 6,6 and secondary cellulose acetate had occurred. However, in the case where colour was developed by diazotising and coupling, excellent wash-fastness properties were exhibited.
