Indigo or slasher dyeing

Mar 15 2014Indigo or slasher dyeing 1 "PRODUCTION OF DENIM FABRIC BY THE USE OF SLASHER DYEING" 2 DEPARTMENT OF TEXTILE ENGINEERING Project Report On "PRODUCTION OF DENIM FABRIC BY THE USE OF SLASHER DYEING" 3 IntroductionIntroduction 4 Denim is the oldest most widely used most fashionable and most versatile fabric of the world

The yarn of Denim fabric is dyed with Indigo dye using slasher dyeing (sheet dyeing) or ball dyeing (rope dyeing) technique During dyeing preferably a ring dyeing is followed in which the dye remains mostly on the outer layer of fibre After air oxidation dyeings are washed through specific technique to remove the excess of color to develop

Mar 10 2009Dyeing: The unique feature in the manufacturing of denim fabric is the dyeing of the warp yarn through a long chain Indigo Dye Range The logs of yarns from the warping process called ball warps are loaded at the entry end of the range and are processed through a series of boxes which contain dye to build the shade and through boxes that rinse the yarn of excess dye

Jan 01 2015Many dyeing techniques such as rope dyeing slasher dyeing and loop dyeing were developed and applied in order to improve the performances of the indigo dyeing process In the early 1990s the pre-reduced indigo (alkaline leuco indigo solution) was prepared by catalytic hydrogenation using Raney nickel as a catalyst and was commercially

[n loop dyeing problems associated with slasher and rope dyeing were solved through the development of a new dyeing technique known as Ioopdye 1 for 6 by Eckhardt Theodor Godau In comparison with other indigo dyeing methods with six colour troughs in loop dyeing there is only one brief indigo dyebath with one squeezing unit

The indigo dye Rope dyeing is the latest dyeing technology in Denim Rope dyeing is considered a superior dyeing technology where the dyeing uniformity is achieved better than other Indigo dyeing technologies like slasher dyeing The technical features of dyeing of sulphur dye are given as follows

Jul 17 2020Indigo dyes are insoluble in water diluted alkalis and acids As they have intra and intermolecular hydrogen bonds indigo dyes have low solubility They have a minimal affinity towards the cotton fabric Schematic diagrams of slasher dyeing are given below –

PRODYE Slasher Indigo Dyeing Machine The perfection solution combined with the best indigo dye tecnhlogy PRODYE is a computer-controlled dye and chemical preparation with a dosing system which enables precise dosing and a uniform stock solution via online ultrasonic indigo preparation

Jan 09 2010In the slasher dyeing method denim yarns in the form of a warpsheet are pre-treated with chemicals and followed by (multiple) dip dyeing in indigo The sheet is then after-treated by washing drying and sizing and a last dry cycle completes the process It is a low-cast alternative to the rope dyeing method One of []

However the indigo dyeing process is widely criticized for poor sustainability 1 An alternative method is called slasher dyeing This method is different only in that beams of parallel yarns are dyed instead of ropes Page 3 of 7 Objectives and Procedures

What is Natural Indigo Dyeing Machine

Jul 19 2017Continuous dyeing of cotton yarn with Indigo Dyeing Machine Indigo denim dyeing: The "Mult-dip" process is by far the only continuous method adopted for indigo yarn dyeing The dyeing machineries used for yarn dyeing are divided into two categories namely the rope dyeing range and the slasher dyeing range Processing Stages Rope Dyeing

In continuous slasher / sheet dyeing and sizing machine direct warping beams are used instead of ball warping logs in case of Indigo rope dyeing system The Slasher Dyeing machine is capable of handling Ne count form 9/s to 30/s (OE and Slub both) At the back end of the slasher / sheet dyeing

This product is a special indigo fixing agents which also inhibits environmental influences such as yellowing caused by corrosive exhaust gases Fixation of indigo dyestuff on jeans and denim garments with PERFIXAN F 5000 lowers bleeding staining and diminishes environmental yellowing

On sheet dyeing ranges (slasher) with process and layout modifications coatings including DyStar Indigo Coat Cassulfon Remazol /Levafix and Imperon dyes can be applied by spray dyeing as well The spray application of fixing agents and oxidation chemicals can be integrated into sheet dyeing (slasher) as well as rope dyeing machines

Until 1915 most Indigo dyeing was conducted in skein machines for cotton or loose fiber dyeing for wool Skein dyeing of Indigo is still the best method for dyeing Indigo on very fine yarns for the delicate high-fashion fabrics In 1915 the first rope dyeing machine appeared and only in the 1970's was sheet dyeing introduced

Sep 02 2015Slasher or sheet dyeing combines dyeing and sizing into a single process Warp yarns are repeatedly passed in warp beam form through several baths of indigo dye before being sized and wound for weaving Slasher dyeing is considered to be lower quality than rope dyeing – the dye does not penetrate well and the color tends to be uneven
