2.8- responsible design Flashcards
(21 cards)
what is PET polyester made from?
recycled plastic bottles or recycled polyester fabric. This type of fabric has a carbon footprint which is 75% lower than polyester made from petrochemicals such as petrol, coal and oil.
what is Econyl?
a type of nylon manufactured using a closed-loop system (just like lyocell) from recycled fishing nets and carpet.
where is bamboo sourced from?
sustainably managed bamboo plantations
where are fairtrade beads, buttons and other components sourced from?
they are sourced from village communities in developing countries that carve the components by hand from wood
what is morphotex?
a biomimetic fibre that does not require dyeing due to its microscopic structure which reflects light as a colour.
what is hemp?
a natural plant fibre which is four times stronger than cotton, twice as resistant to abrasion, and more resistant to mildew, soiling, shrinkage and fading in the sun. Hemp plants require much less water than cotton and less agricultural chemicals, and do not deplete soil nutrients. It is also easy to harvest
what is Ahimsa?
also known as peace silk- it is produced humanely by letting the moths/silk worms hatch out of the silk cocoon before using it. The moths are not killed, but the silk is far more expensive due to the extra time allowed for the pupae to develop and hatch
what was morphotex inspired by as a biomimetic fibre?
Biomimetic fibres such as morphotex are man-made fibres which imitate nature. The inspiration for morphotex came from the studying of the wing surface structure of the blue morph butterfly- light refracted from the surface of the fabric, creating a blue/violet colour, but the fabric itself was never dyed.
what is fast fashion?
fashion clothing produced rapidly to satisfy demand for the latest trends. Production and distribution is rapid, with shop stock quickly replenished
what is cradle to cradle clothing?
garments which are designed with the entire lifecycle in mind- instead of ending up in landfill ‘cradle to grave’, these clothes are either biodegraded and returned to nature, or fully recycled into new products without creating waste.
how can fibres be reused in ‘cradle to cradle’ clothing?
- used textiles can be shredded into loose fibres and then spun into new yarns and made into new fabrics- for example this is typically used with wool fibres
- fibre blends such as polyester and cotton can make reclaiming fibres more difficult, especially when dyes need to be reclaimed
what are returnity and infinity?
100% recyclable polyester fibres. They are used in clothing designed to be zero waste,
what is infinity?
a strong and comfortable polyester fibre which is produced using 50% of water use and 20% of carbon dioxide emissions in comparison to conventional cotton.
what are some ways that consumers can support the movement of ‘slow fashion’?
- choose fashion and textile products made from organic fibres grown without toxic chemicals
- support fairtrade companies who pay their employees a living wage with reasonable working conditions and no child labour
- choose locally made products or those that have not been imported from countries across the globe to reduce ‘fashion miles’ and carbon footprint.
what are some different examples of how consumers can care for products to be more environmentally friendly?
- wash clothes only when they are dirty, using eco-friendly detergents at lower temperatures (30 degrees), and avoid tumble drying and ironing to conserve energy
- use washing machines which are energy efficient and use less water.
- wash a full load of clothes rather than multiple smaller loads
- careful storage can extend a products life spans, for example away from direct sunlight, moths and damp conditions
what is patching?
applying a small piece of fabric over a hole or damaged area of the fabric to extend the products life span
what is darning?
a stitch technique used for repairing holes or worn areas in the fabric to extend the products life span
what is a circular economy?
where the life span of the product is extended by continuously repairing and upcycling the product until it has no further use.
what are azo dyes and pigments?
bright chemical dyes used to colour textile materials which have been linked to causing cancers
how can sunlight be used to bleach natural fabrics?
sunlight can be used to bleach natural fabrics combined with natural dyes from organic sources such as plant roots, berries, bark, leaves and wood
what happens in organic cotton farming?
crop rotation maintains the nutrients in the soil, traps can be used to catch pests and cow dung is used to fertilise crops (instead of harmful chemicals and pesticides) and natural predators like birds and insects are exploited to promote cotton plant growth by controlling pests and weeds, which are competing with the cotton plants for water and soil nutrients
