Nomex is a synthetic aromatic polyamide fiber created by DuPont in the 1960s. It is heat and flame resistant and will not melt or burn. Nomex is used in protective clothing for firefighters, race car drivers, and military personnel. It has excellent chemical resistance, temperature resistance, and strength. However, it is not biodegradable and can cause lung damage or eye irritation if mishandled.
Aramid fiber are one of the high thermal high performance(HT-HP) modern fibers that are potentially of interest in civil, defence, automobile industries, and Technical textile fields. Being characterized by high strength, high stiffness, low creep and resistance to corrosion un-like carbon or glass fiber. However the aramid fiber are frequently used with out resin impregnation to resistance of fire.
Eg.- Kevlar, Nomex, Twaron, and Technora are commercial name of aramid fiber.
H.P. fibres are the fibres which have which have high strength, temperature resistance, good flexibility, light weight, fine diameter & durability etc. Qualities are used mainly for technical textile purpose.

Technical fiber or High functional fibers
High functional fibers are those, which have high technical properties based on the end uses. The properties are high tensile strength, high modulus, good chemical resistance, high dimensional stability, low thermal resistance.

The design, manufacture and applications of fibre composites in space and aerospace has become one of the most predominant aspects in present-day textiles.
The applications of fibre composites in
space suits for launch and space walks
require zero defect performance.
They are made from PBI non-flammable
high performance fibres, which require
air purifying, cooling and pressurising
systems, so that the suit should be
thermal resistant and thermal insulated
Unifrax is a leading producer of high-temperature insulation products providing innovative heat management solutions and energy savings for a broad range of industries.
Our well-known Fiberfrax® ceramic fiber products, Insulfrax® and Isofrax® soluble fiber products and other high performance insulation products provide substantial improvement in thermal performance, save thousands of dollars in energy costs and can help reduce your operations environmental footprint.
Unifrax also maintains a leadership role regarding industry health and safe handling of products through our Product Stewardship Program (PSP) which serves as a model for the industry.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
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.

3. Nomex was first created back in the early 1960s but would be marketed in 1967. Dr. Wilfred
Sweeney created it in the now world-renowned DuPont laboratory. Nomex’s technical name
is ‘Synthetic Aromatic Polyamide Polymer’.
In early 1966 Competition Press and Auto week reported: "During the past season, experimental
driving suits were worn by Walt Hansgen, Masten Gregory, Marvin Panch and Group 44's Bob Tullius.
4. The properties of Nomex include great electrical insulation properties at high temperatures.
The general properties of Nomex are listed below.

6. The chemical name of Nomex is poly (m-phenylenediamine isophthalamide), which is
produced from the reaction of m-phenylenediamine and isophthaloyl chloride whose
structures are shown below :
8. Abrasion
Chemical resistance
