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.

*State Level Single Window Clearance Authority Approves 10 Industrial Projects*

*Projects worth INR 1923.6 cr got clearance at one go Employment generation is likely to be more than 5000*

*Bhubaneswar, 8th October 2022:* State Level Single Window Clearance Authority (SLSWCA) of the Govt of Odisha today held its 113th meeting under the chairpersonship of the Chief Secretary of Odisha, Suresh Chandra Mahapatra (IAS). The committee approved 10 industrial projects worth Rs 1923.60 crores that would generate employment opportunities for over 5,170 people in the state.

The projects approved in the meeting belonged to diverse sectors like Power & Renewable Energy, Chemicals, IT&ESDM, Food Processing, Oil & Gas, Metal downstream, Technical Textiles, Tourism and Infrastructure. The approved projects will be set up across Odisha with 4 of the projects being set up in Khordha, and 1 each in Puri, Jagatsinghpur, Kendrapada, Balasore, Keonjhar and Angul.

The SLSWCA approved the proposal of M/s Luminous Power Technologies Private Limited to set up a manufacturing unit of new technology eco-friendly Batteries Fuel Cell, Advanced Chemistry Cell (ACC batteries), and Power storage & Solar batteries in the Angul Aluminium Park with a proposed investment of Rs 481 Crores generating employment for over 1,150 people in the state.

The committee gave a nod to the proposal of M/s Silox India Private Limited to set up a chemical manufacturing unit in the Paradeep Industrial Area. The unit is expected to produce 25000 MTPA Sodium Formaldehyde Sulphoxylate, 2000 MTPA Zinc Formaldehyde Sulphoxylate & 15000 MTP Metal Salts of Cobalt, Nickel, Magnesium, Lithium, and Zinc. The unit is being set up with an investment of Rs 500 crore and is expected to generate employment opportunities for over 800 people in the state.

The committee also approved the investment of Rs 265 crore of M/s Happiest Minds Technologies Limited in setting up a software development centre facility offering IT services at O-Hub in Info-valley SEZ, Bhubaneswar. The project is expected to create over 1500 highly skilled job opportunities in the state.

In the Hospitality sector, the committee approved M/s MGM Resorts Pvt. Ltd.’s 5-star Hotel Hyatt Regency with an investment of Rs 180 Crores. The project will be coming up in the New Marine Drive Road, Puri. The committee also approved M/s Oil India Limited’s Oil and Gas exploration units with an installed capacity of 10KLPD each in Astaranga, Puri and Patkura, Kendrapada. OIL will be investing over Rs 108 crores in the state creating employment opportunities for over 115 people in these two locations.

In the agro and food processing sector, the Rs 150 crore worth aqua feed manufacturing facility with an annual capacity of 1,80,000 MT proposed by M/s IFB Agro Industries Limited was also approved by the committee. The project will be set up in the Somanathpur Industrial Estate, Balasore with an estimated employment potential of over 270.

The Government of Odisha has been keen on broad-basing the industrial outlook of the state along with bringing in investments in employment-intensive sectors. These approved projects in the 113th SLSWCA belong to a diverse set of employment-intensive sectors and highlight the success of the government in pursuing broad-based industrialization in the state. While Odisha has always been a destination of choice for the mineral and metallurgy sector, the stable and progressive governance over the last two decades along with factors like fast technology adoption by the state and a highly skilled workforce are contributing to the development of Odisha as an Industrial Hub in Eastern India and possibly, a fulcrum for industrial and trade-related activities in the East and South-East Asian region.
