Difference between reactive dye and disperse dye on fabricAzmir Latif Beg
We are introducing about reactive dye and disperse dye on fabric. At present reactive dye and disperse dyes is not a single word globally now it achieved vast sector in dyeing sector. I just try to make a different reactive dye and disperse dye on fabric application based.
Lab dip is a process by which buyers supplied swatch is matched with the varying dyes percentage in the laboratory with or without help of “DATA COLOR”
Lab dip plays an important role in shade matching & and detaching the characteristics of the dyes and chemicals are to be used in the large scale of production. So this is an important task before bulk production.

Scope of Dyeing Polyester Cotton (PC) Blended Fabric in Single Bath Process f...iosrjce
Dyeing of fabric blends such as Polyester/Cotton (P/C) is presently done with two
chemically different classes of dyes namely disperse for polyester and reactive for cotton, in
two bath process. Experimental work was carried out on finding the possibility of dyeing the
P/C blends in one bath process without drain the liquor after polyester part dyeing. All the
existing chemical and conventional temperature range were applied in this study. The result
indicates that, the using of one bath method in the polyester cotton dyeing can slightly change
the fastness properties than the conventional method. The one bath dyeing method showed
level dyeing having good fastness properties and offers the option of cost effective and ecofriendly
dyeing process.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

14. 1. Hot reactive dyes
Reactive dyes which have low reactivity ( monochlorotriazin
faction )
Example of : Procion HE type ( ICI ) , Begative HE type
( Colorindo )
2. Cool reactive dyes
Reactive dyes which have high reactivity ( dichlorotriazin faction )
Example : Procion MX type ( ICI )
Based on its reactivity , reactive dye divided 2 faction :
19. Side Reaction
•Hydrolysis of dichlorotriazine
1.Results in wasted dye
2.Economic and environmental concern
•Typically fixation of around 60% is obtained
20. Dyeing Conditions
Time allowed for diffusion of dye into substrate
‰ Concentration of dye in fiber is up to 500 times greater than in solution
Acidity difference creates ~25-fold excess cellulose anion
21. Leaving Groups
Variation of substituents = variations in fixation
‰ “Cold” dyes = fixation temperature of 30-40°C
‰ “Warm” dyes = fixation temperature of 50-80°C
‰ “Hot” dyes = fixation temperature of >80°C

REACTIVE DYES
This is an entirely class of dye
introduced to the market in 1956.
They react chemically with the fibre
being dyed & if correctly applied,
cannot be removed by washing or
boiling.

REACTIVE DYES
The main feature of
the dyestuff is its low
affinity to cellulose;
therefore large
amounts of salt are
required to force its
deposition on he
fabric.
24. 2004
24
REACTIVE DYES
After this has been
achieved, addition of
alkali causes the
deposited dyes to react
with the fibre.
Only a successfully
concluded reaction
guarantees a fast
dyeing.
Basically there are two
types of reactive dyes:
the cold dyeing & hot
dyeing types.
25. 2004
25
REACTIVE DYES - USE:
Reactive dyes are used where
bright dyeing with high light &
wash fastness is required.
Cold dyeing is used extensively
in batik work.
Although some reactive
dyestuffs have been specially
modified to dye wool, their main
usage is in dyeing cotton linen &
viscose rayon.

REACTIVE DYES Cold water fibre reactive
dyes, suitable for dyeing on
cotton, silk, jute, rayon &
hessian.
Cannot be used on
synthetics or fabric that
has been coated with resin
or drip-dry finish.

DISPERSE DYES
The introduction of a new regenerated
cellulose acetate fibre in 1920 led to the
necessity to develop an entirely new range of
dyes.
It was found that acetate (or Celanese) fibre
had hardly any affinity for water-soluble dyes.
A new dyeing principle was introduced: dyeing
with water dispersed coloured organic
substances.
These finely coloured particles are applied in
aqueous dispersion to the acetate material &
actually dissolved in the fibres.
32. 2004
32
DISPERSE DYES - USE:
Basically developed for dyeing of
acetate fibres, Disperse dyes are also
used for dyeing of polyamide (Nylon)
& acrylic (Orlon & Acrylan) fibres.
With the addition of 'carriers' or
swelling agents these dyes are also
used in dyeing of Polyester (Terylene,
Dacron, etc.)

40. Dyeing of polyester/cotton blend
Three well known exhaust dyeing procedures :
(1) a conventional two bath procedure
(2) a reverse two bath procedure
(3) a one bath, multi step procedure
41. (1) The conventional two bath procedure
1. first dyed with a disperse dye at pH 5-7 at 120°-140° C to dye the
polyester.
2. removed from this first dye bath and transferred to a second dye
bath containing a fiber reactive dye, electrolyte and alkali.
(2)The reverse two bath procedure
1.first dyeing the cotton with the fiber reactive dye
2. dyed the polyester with the disperse dye in separate dye baths.
42. (3) In the one bath multi-step procedure
1. a single dye bath is prepared and the cotton portion of the blend is
dyed alkaline conditions low temperature the presence of
electrolyte.
2.The dye bath is then acidified to lower the pH and a disperse dye is
added
the polyester portion of the blend is dyed at 120° C. to 130° C.
