  • ENVIRONMENTAL FACTORS
    • TEXTILES AND THE ENVIRONMENT
      • The impact of textiles on the environment
        • have large impact because at everystage of the product's lifecycle
          • energy and resources are used
          • waste is produced
        • have a large carbon footprint
          • measure of the amout of co2 produced directly or indirectly because of an individual or product
      • manufacturing textiles
        • dying and finishing processes use lots of chemicals
          • chemical dyes
          • resins to make fabrics shrink proof
          • softners used to improve feel of fabric
            • chemical waste
              • resins to make fabrics shrink proof
              • chemical dyes
        • also require energy to drive machinery and contaminate large volumes of water
        • solutins for reducing impact
          • cold water dyes or dyes that use less energy
          • renewable energy sources
          • reducing need for dark dyes
            • require a lot of rinsing to remove excess dye
          • using natural dyes
            • plants
              • insects
          • naturally coloured yarns
            • eliminates dye process
          • develop finishing processes
            • that require less energy
          • using fabrics that already have desired properties
            • lyocell is resistant to shrinkage and wrinkling
      • sustainability
        • natural fibres must comes from a sustainable sour
          • sources that are carefully managed so plants and animals are replaced
        • collecting large amounts from the wild would deplete natural reserves
          • extinction in some cases
        • scientists exploring the possibility of producing natural materials without the use of plants an animals
          • e.g. victimless leather
            • grown from cells in lab
            • called biotechnology
      • laundry and aftercare
        • most product needs cleaning and maintaining throughout their life
          • energy used in processes of washing drying and ironing can be reduced
            • durable and easy to care for fabrics
              • longer lifespan
            • more info to consumer
              • care for product effectively
            • products that can be washed at low temps or cold water
            • avoid dry clean only fabrics
            • using fabrics that require no or little ironing
      • waste textiles
        • off cuts and other textiles often go to waste
        • how can we reuse and reuduce?
          • computerised lay platting
            • lay cutting
          • use fabric scraps
            • in automotice industry
            • e.g. emergency relief blankets
          • look at ways of using waste textiles in the manufacture of new textiles
            • Muji has a range of textile products made prom textile waste and excess yarns that would normally be thrown
      • design obsolence
        • fashion industry encourages consumers to continuously update their wardrobes with the latest trends
          • good become obsolete even though still in good condition
        • or planned obsolence
      • disposal
        • critical
        • if product is throuwn out as refuse it is put in landfill or incinerated
        • to prevent materials being wasted and safe energy
          • as less need to manufactured
          • reuse
          • recycle
    • DESIGNER RESPONSIBILITY
      • design
        • durable products
        • design reusable products
          • instead of disposable
        • source local materials
          • transportation
      • fabrics
        • consider the specification
          • organic cotton over inorganic
        • colours
        • avoid fabricsneedeing special ccare or cleaning
        • recycled materials
      • components
        • check what are made from
          • electroplated?
        • reduce number
        • recycled components
      • production
        • reusable pattern blocks
        • minimise fabric and yarn wastage
        • processes that produce less waste
        • carbon offsetting
        • explore methods of reducing greenhouse gas
        • Kyoto protocol
      • end use
        • clear aftercare instructions
        • label has info on how to recycle materials
        • donate or resell
    • RECYCLING
      • Mobius loop
      • may need processing before a product can be reused
      • three types of recycling
        • primary
          • reused in current state
          • e.g. taking clothes to charity shop
        • physical or secondary
          • torn
            • before being reused
              • melted
              • e.h. woollen garments shredded and used as stuffing or industrial felting
          • shredded
            • before being reused
              • melted
              • e.h. woollen garments shredded and used as stuffing or industrial felting
          • ground
          • chemical or tertiary
            • products are broken down and reformulated
            • e.g. PET plastic bottles are broken down into fibres then spun into polyester to make fleeces or duvets
        • importance of recycling
          • textiles products use a lot of resources so it is important to reuse them rather than let them go to waste
            • key resons are to save energy , raw materials and reduce the need to manufacture new products
          • designers try and think of new ways to recycle products
      • REYCLING AND ETHICAL GOODS
    • chemical waste
      • using biomass to produce biofuels for transportation
        • solutins for reducing impact
          • cold water dyes or dyes that use less energy
          • renewable energy sources
          • reducing need for dark dyes
            • require a lot of rinsing to remove excess dye
          • using natural dyes
            • plants
              • insects
          • naturally coloured yarns
            • eliminates dye process
          • develop finishing processes
            • that require less energy
          • using fabrics that already have desired properties
            • lyocell is resistant to shrinkage and wrinkling
