• Dyeing conditions: Dye selection is crucial as individual dye behaviour is quite different from PET dyeing PLA can be dyed with disperse dye at 110-115c for 15-30 minutes at PH4 5-5 • Dye uptake: Diffusion coefficient in PLA fibre was much higher than that in the PET Dye uptake for PET fibre increases in proportion to the dye bath
Jul 13 2016Rit Dye More is blended with synthetic pigments and contains a type of dye called disperse dye This newly released formula can dye polyester acrylic acetate nylon and polyester/cotton blend fabrics as well as other synthetic materials So I took a more aggressive approach this time around and mixed acetone with the newly-purchased Rit formula
Dyes can form chelates with different mordants to develop various shades with superior wash fastness Na 2 Cr 2 O 7 and K 2 Cr 2 O 7 are the commonly used mordants for wool because of the presence of reducing thiol groups absence of such reducing groups in silk can be overcome by using basic salts of chromium to form dye–chromium complex
Direct dyes are developed to produce a different shade or to improve washfastness or lightfastness Azo Dyes Dyes characterized by the presence of an azo group (-N=N-) as the chromophore Azo dyes are found in many of the synthetic dye classes Aniline Dyes Dyes derived chemically from aniline or other coal tar derivatives Anthraquinone Dyes
After PET part dyeing cool to 80c for proper levelling then add NaOH Na2S2O 4 + dyeing 15min + cooling to 60c + dyeing for 30 min for better exhaustion Rinse with cold water + oxidation with H2O2 for 15min at 50c + Rinsing with cold water + Soap at 95 C for 25 min using 2 g/l Lissapol D + Hot and cold rinse and then final wash off
Dyes are a large and important group of chemicals among the different pollutants of the aquatic ecosystem They are widely used in industry to colour products such as textile paper rubber plastic cosmetic etc The dyes are invariably left in the industrial wastewater which are subsequently discharged mostly into surface water resources

Jan 15 2014Polyester requires the use of disperse dyes Other types of dyes leave the color of polyester almost entirely unchanged While novices happily charge into dyeing with acid dyes (for wool or nylon) and fiber reactive dyes (for cotton and rayon) often with excellent results the immersion dyeing of polyester is a different story
phase anchor to functionalize polyolefins with dyes This is illustrated by preparing PIB-bound metallophthalocyanine dyes in a series of reactions starting with 4-nitro phthalonitrile The non-polar solvent solubility of these dyes allowed their use in dyeing commercial polyethylene and polypropylene

Jun 01 2014In this investigation the sheath-core polyester/co-polypropylene composite fibers (PET/co-PP fibers) were annealed at 150 C for 1 h and dyed with three types of disperse dyes using scCO 2 at the various dyeing temperatures and pressures Optical and scanning electron microscopes (SEM) were used to examine the cross section of the fibers
