Color fastness properties of different reactive dyesAzmir Latif Beg
In knitwear industry, dyeing of cotton knitted fabrics is mostly done with reactive dyes, because of their good fastness properties and versatility of applications. The ease of application, wide shade range, high brilliancy and excellent wet fastness properties make the reactive dyes preferred choice for the dyeing of cellulosic fabrics. The most important characteristic of reactive dyes is the formation of covalent bonds with the substrate to be colored, i.e. the dye forms a chemical bond with cellulose. Fiber reactive dyes are the most permanent of all dye types. Unlike other dyes, it actually forms a covalent bond with the cellulose or protein molecule. Once the bond is formed, what you have is one molecule, as the dye molecule has become an actual part of the cellulose fiber molecule.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

12. Chemical Protection
• Protective clothing cannot be made generic for all chemical
applications, since chemicals vary in most cases and a particular
CPC can protect only against a limited number of specific
chemicals.
• Important considerations in designing chemical protective
clothing are
– The amount of chemical permeation.
– Breakthrough time for penetration.
– Liquid repellency.
– Physical properties of the CPC in specific chemical conditions.
12
13. Requirements
• Chemical Protective Clothing Should Resist :
Permeation , Degradation, Penetration.
• Durability
• Flexibility
• Temperature Resistance
• Service Life
• Clean Ability
13
14. Textile Materials
• Ordinary textile materials are generally not considered suitable for protection
against chemicals, however special non-coated textile materials are used for a
variety of applications involving particulates and light liquid spray from relatively
non-hazardous chemicals.
• Though woven textiles are not often found in chemical protective clothing, very
tightly woven, repellent-treated fabrics can provide some very low minimum
protection against liquid exposure.
• More common are nonwoven fabrics that have demonstrated barrier performance
against particles and repellency of liquids.
• Two predominant examples of non- woven fabrics are flashspun polyethylene
(Tyvek) and spunbond/ meltbown/ spunbond (SMS) polypropylene (Kleenguard).
• These textiles are used because of their relatively low cost and because the
materials provide a structure of microfibers that filter out dry particulates and
many water-based liquids.
14
15. Adsorbent-Based Materials
• These materials include adsorbents, such as
activated charcoal or other sorbent materials.
• Activated Carbon : Activated carbon in very fine
powder or granular form is useful to purify both
water and air. Activated carbon has particular
affinity to organic materials such as solvents used in
printing inks and common coatings.

The term `electrostatic' or `static electricity' refers to
the phenomenon associated with the build up of
electrical charges generated, for example, by contact
and/or rubbing of two objects. Static electricity is
generated by unbalancing the molecular configuration
of relatively non-conductive materials.
