What is a smart fabric? | It is a fabric that can react to outside conditions without human intervention. |
Define a smart fabric. | In simple terms, smart textiles can sense electrical, thermal, chemical, magnetic, or other physical responses from the environment, and adapt or respond to them. |
What do smart fabrics do? | Smart materials sense the conditions around them, and react in some way. |
What does hydrochromic mean? | Changes colour in contact with water. |
What is the name of a fabric that changes colour with temperature? | Thermochromic. |
What does photochromic mean? | Responds to light by changing colour. |
What are conductive fabrics? | Conductive fabrics have metal fibres or conductive printing inks/coatings on the surface. GORIX is a carbonising fibre that is conductive used in heated car seats and for motorbike clothing. SOFT SWITCH has conductive fibres that have pressure sensor use |
What sort of fabric is gore-tex? | This is a laminated fabric, made up of different layers that have different functions. Gore-tex is widely used for outdoor wear.. |
Name a biomimetic fabric and explain why it is biomimetic. | Fastskin, developed by Speedo, mimicks sharkskin so it channels water away from the body making the swimmer more aerodynamic. |
What is microencapsulation? | Micro-encapsulation allows fibres and fabrics to be impregnated with microscopic bubbles of perfumes, anti bacterial properties, anti-allergenic properties, insect repellents, and carbon digesters to absorb smells. |
What is an alginate dressing? | These are highly absorbent, biodegradable dressings derived from seaweed. They promote healing of tissues and prevent bacterial infection. They are used on wounds that are really weeping, |
What is nanotechnology? | Thin layers of nanoparticles (very tiny particles of a substance) can be attached to common fibres and fabrics. The layers are so thin that they don’t change the feel of the fabric. |
What are microfibres? | 60 times finer than human hair Made from polyester or polyamide Very strong Water-repellent Absorbent Breathable Very good |
What are microfibres used for? | Hosiery Sportswear Water- repellent outdoor wear Cleaning cloths |
What is Nomex? | Nomex– very resistant to fire and so used in firefighter uniforms and racing driver |
