Transcript of Smart and technical textiles

What are smart technical textiles? As a group, discuss

- What Smart and Technical textiles are?

and

- Who uses them?

Write your findings on the paper provided

Elect one speaker from each group to present the groups ideas to the class. Aspire Challenge
- X-Static is the name of new yarn which uses silver in its production.

-Trials have shown it will eliminate 99.9% of bacteria within 1 hour, including MRSA

- Future uses could be hospital bedding and pyjamas.

- Silver technology is appearing in the highstreet now. Have you seen any? Technical Fabrics used by the armed services and police force Why do I need to learn about Smart and Technical fabrics? Smart and Technical Textiles This subject is often included in your GCSE exam. You have three minutes! - Technical textiles have been developed for their performance, and functional properties. What are smart and technical textiles? Combating MRSA in hospitals Technical textiles are all around us - The building industry
-The agricultural industry
-The medical industry
-Motor vehicle industries
-The Armed forces and the police
- Sportsmen and women
- Artists and designers Who uses them? Technical Smart -Smart textiles are designed to react to conditions around them.

-They can respond to...

-Hot or cold temperatures
-Light
-Pressure
-Power
-Time Technical Textiles Here are a few... Fire retardant used in formula 1 (and also oven gloves)



Water repellent and windproof: used in cycle jackets, outdoor wear. Nomex Gore-Tex Breathable Fabrics Stomatex Also known as CoolMax was developed for sportswear.

It transports moisture away from the body to the surface of the fabric, to keep you dry and comfortable. As well as all types of sportswear (sports bras, shirts, tracksuits) this fabric is used in the mat that fits under the saddle in horse-riding. Kevlar is used for? Reminder time... 1. Fire retardant used in formula 1 (and also oven gloves)


2. Water repellent and windproof, used in cycle jackets, outdoor wear. 3. developed for sportswear. It transports moisture away from the body to the surface of the fabric, to keep you dry and comfortable. 1. 8 times Stronger than steel on an equal weight basis. Used in bicycle tires and body armor Reminder time... technical design challenge d3o- - d3o is a revolutionary new material that is soft and flexible during normal use.


- Upon impact its molecules lock together, stiffening the material and providing superior protection! The material then softens again immediately following impact!


- This allows you to use it over and over again, unlike helmets which must be replaced after a large impact. 1. Get into groups of four

2. Brain storm ideas together

3. Start designing

4. Annotate your designs using the correct terminology

5. You must justify your ideas. You have five minutes to design a super revolutionary technical product. Smart Textiles Electronic textiles- These are becoming more common and are fast-growing part of the textiles industry. Conductive thread-

Soft switches can be incorporated into garments or products which have been woven with conductive thread.
2. Soft switches can be incorporated into garments or products which have been woven with conductive thread. Memory textiles - Temperature and pressure sensitive foam that moulds to the shape of the body and returns to normal when pressure is removed. Originally developed by NASSA

to help astronauts deal with G-Force when blasting off into space Micro- encapsulation- Chemicals/ Fragrances are captured in microscopic bubbles which are added to micro fibers. When the fibers are rubbed the bubbles slowly burst and release their content. What is this used for? 3. Chemicals/ Fragrances are captured in microscopic bubbles which are added to micro fibers. When the fibers are rubbed the content is released 1. Temperature and pressure sensitive foam that moulds to the shape of the body and returns to normal when pressure is removed. 2. Upon impact its molecules lock together, stiffening the material and providing superior protection! The material then softens again immediately following impact! Reminder time... Thermochromic dyes- Thermo chromic - is a substance that changes color due to a change in temperature.
A mood ring is an excellent example of this phenomenon,
thermo chromism also has more practical uses,

Baby bottles (changes to a different color when cool enough to drink) Phosphorescent Pigments- What is this? Write down five phosporesent products and why they are useful? Phosphorescent pigments glow in the dark.

They are able to absorb light energy and store it, this energy is released when the light changes.


Phosphorescent pigments are used in fire safety signs placed near fire extinguishers. In the event of a fire, the position of the fire extinguishers can be seen, even if the lights fail.
1. A substance that is sensitive to temperature. It change colour when they are heated up or cooled down. Reminder time... 2. Pigments that glow in the dark. They are able to absorb light energy and store it, this energy is released when the light changes. technical design challenge
•To extend and build upon your knowledge of what smart and technical fabrics are, and be able to give valid examples of their applications, advantages and disadvantages. •Yourself to understand the meanings of each smart and technical textile definition by the end of this lesson. Challenge:
Match up the soft switch images and descriptions on your tables. Our aspirations for today was... P.I.N mark Praise - What aspect of this work is outstanding?

Improvement- Literacy improvements to be made?

Next step- How could you further revolutionise this design? 8 times Stronger than steel on an equal weight basis. Body Armor The Police
Fire Fighters
The Army What other technical textile could be used to ensure complete protection? Also used in bicycle tires Did you know........ Kevlar is To extend and build upon your knowledge of what smart and technical fabrics are, and be able to give valid examples of their applications, advantages and disadvantages.
