Weft knitting machine & parameters of weft knitted fabricAzmir Latif Beg
Knitting is the interloping of yarn which is interlocking in various ways to form fabric. Knitting is the process of manufacturing fabric by transforming continuous strands of yarn into a series of interlocking loops, each row of such loops hanging from the one immediately preceding it. The basic element of knit fabric structure is the loop intermeshed with the loop adjacent to it on both sides and above and below it.

A Strategic Approach: GenAI in EducationPeter 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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

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.

3. CULTIVATION OF COTTON
Cotton grows from seeds
Cultivated on fields
To make it into yarn, the cotton
bolls are collected and packed tight
- Bale
4. BALE AND RAW COTTON
Cotton from the bale is unpacked for further spinning process
5. GINNING - SEED REMOVED
Ginning is the process in which
the cotton collected from field is
processed to remove the fibre and
trash (waste) separately
7. SPINNING MILL
1. BLOW ROOM
After ginning the fibres reach the spinning mill, where the fibre is
made into a yarn
Here the bale (fibres) are opened
The suction moves over the bale, and starts opening the sucked
fibres by using rush of air
OPENING – CLEANING – BLENDING – MIXING
8. 2. LAP FORMATION
The opened fibres are made into a soft roll or lap
by removing of waste particles
LAP IS SHEET OF FIBERS – WIDE IN LENGTH
9. 3. CARDING
Opened fibers are passed between
rollers with comb
Removal of trash and short fibres
Fibers drawn together are made
into a loose rope - sliver
Carded sliver
10. 4. COMBING
Additional process of combing
is done – remove short fibres
and obtain high quality – voile
& organdie
COMBED
SLIVER yarn
11. 5. DRAFTING / DRAWING
The combed/ carded
lap is reduced in
diameter
Slivers are combined –
smoothened &
stretched
12. 6. ROVING
▪ Yarn diameter is reduced to
diameter of a pencil led
▪ Bobbins are placed on roving frame
where further drawing and twisting
is done
DRAFTED YARN
15. STEPS IN SPINNING

7. SPINNING
16. YARN DEFECTSYARN DEFECTS
Yarn quality is affected
by % of yarn fault.
Analysing is important
because;
Causes breaks during
post spinning
operations.
Detract aesthetic appeal
of the fabric , if allowed
to pass
17. YARN DEFECTSYARN DEFECTS
Appearance and strength is affected by yarn quality
Spinning ability and fabric appearance is affected by yarn
quality
Yarn quality decides on acceptance/ rejection of the piece
A fault-free thread is important, because every unwanted
yarn can create a problem.
With poor yarn quality good quality fabric cannot be
made
FAULT FREE – IMPOSSIBLE, but defects can be
reduced by keeping machine clean and process control.
23. Other faults
▪Imperfection at thick and thin place
▪Oil stained yarn
▪Crackers (coils) inside the yarn
▪Kitty yarn – presence of trash in yarn
Other faults: Hairy yarn, Foreign matter,
Spun in fly, Slough off, Knots, Excessive
hard yarn , Rust stain, Low strength yarn,
Bad piecing are some of the other types of
yarn defects

26. Sewing thread is
flexible, small diameter
yarn
that is given surface
coating or lubricant
or both,
that helps in stitching
one or more pieces of
fabric/ material/ object
together
SEWING THREAD - INTRODUCTION
27. ▪ Thread should be as fine as possible depending on the
required strength of the seam.
▪ Special kind of yarn engineered to pass through the
sewing machine rapidly
▪ Most single needle lock stitch and other machines are
designed for Z twist threads
▪ S twist yarns tend to twist during stitching
SEWING THREAD
Design/ Specification
28. SEWING THREAD : PROPERTIES
Sewing thread should be uniform, knot
and fault free and should be easily able to
pass through the needle hole
Tensile/ breaking strength are important
in evaluating the quality of sewing thread
They should have good life time along
with life time of being inside the finished
product
29. ▪ Industry power operated machines
performance is based on sewing threads quality
▪ Quality of sewing thread affect the seam quality
and production cost
▪ Material to sew, sewing technique, end use
determines the sewing performance.
▪ Ability to give the required aesthetics and
serviceability are important in a sewing thread
SEWING THREAD : PROPERTIES
30. QUALITIES OF GOOD SEWING THREAD
Uniform thickness/ diameter – successful smooth sewing
Good colour fastness – good thread should sustain washing, sun drying
and still hold same colour
Good abrasion resistance – enable good sewing and high productivity
Good resistance to chemicals and perspiration (sweat)
Washing, bleaching and dry cleaning – chemicals used in that
31. SEWING THREAD
▪ Overall thickness of the thread - size of
sewing thread denoted by ticket
number/ Tex/ count
32. FIBRES USED
Natural :
Cotton is the common fibre in sewing thread and mostly used in industrial sewing
Man made:
High tenacity
High resistance to abrasion
Good resistance to chemicals
Not affected by moisture, rot and mildew – appreciable properties
Eg1: Spun polyester: Commonly used, variety of size and colour
Eg 2: Core Spun thread: core-polyester/ wound by cotton/polyester
