This book highlights the innovations in textile fibres, that is the starting point of the supply chain. There are numerous innovations made in terms of making the existing fibres sustainable and also to discover new sustainable fibres. This book . This review describes the immense impact of reactive dyes on the textile industry. Their use on cellulosic fibres is especially important, but their growing popularity on polyamide .
MIXTURE DYES: Disperse/wool dye mixture- available since , suitable for PET/wool Advantages: *simplified selection, reduced weighing/handling of dyes * good reproducibility (from batch to batch or bulk scale) * tone and tone dyeings 5/5(2). Process for producing dyeing of constant color with mixtures of substantive reactive dyes on substrates of natural or modified fiber materials containing hydroxyl groups .

For dyeing of cotton fabrics with reactive dyes, dye fixation rate and the treatment of dyeing effluent are still the important determinant of environmental impacts and dyeing cost (Biolchi et Cited by: Environmental responsibility is best achieved in cold pad batch application since little or no electrolyte is required, dye fixation is at ambient temperature, and fixation is high.
Cited by: 2. Ultra sonication was also able to reduce the dyeing time of cotton fabric using reactive dyes in cold pad batch dyeing process where the dyeing time was reduced to 8 h compared to the. A hydrolysed dye is not able to react with cotton and is removed through washing-off.
A dye fixation efficiency of up to 99% is sometimes claimed for some reactive dyes with pad-batch Cited by: Two types of reactive dyes (CI Reactive red and CI Reactive yellow ) were doped with different amounts (,and mol) of TiO2 nano-sol by sol–gel method and.
The fabric is first padded in a padding mangle with reactive dye in presence of an alkali. The padded fabric is rolled in a batch and the batches are wrapped by polyethylene sheets and. Ciba-Geigy has developed a new generation of bifunctional reactive dyes having a new aliphatic vinyl sulfone group combined with either a monofluorotriazine group or an aromatic vinyl.
Orco Reactive BF-Series™ reactive dyes are comprised of vinyl sulfone and monochlorotriazine linking groups offering benefits of both the Orco Reactive R-Series™ and ORCO Reactive I-Series™ reactive dyes, respectively.
These are more stable to temperature, liquor-ratio, salt, and pH variations, thus providing excellent reproducibility. COLD PAD BATCH dyeing is a more environmentally sound and higher quality dyeing method for woven and knitted cotton/viscose fibers.
The process removes salt from the eﬄuent, reduces the use of water, energy, reduces the volume of eﬄuent and occupies less bifunctional reactive dyes for CPB dyeing reproducibility File Size: 1MB.
