what are the properties of goretex which makes it suitable for outdoor clothing
- breathable
- water proof
- windproof
- light weight
describe the apperence and characteristics of crepe fabric
- bumpy surface
- made with highly twisted yarns
- recognised for good draping qualities
- usually made from wool or silk fibres
- plain weave
- luxurious
describe the appearance and characteristics of gingham fabric
- plain weave
- 2 different coloured yarns are used
- usually characterised by checks, plaid or stripes
- usually made from cotton or polycotton
describe the appearance and characteristics of taffeta fabrics
- crisp fabric which makes a ruffling sound with movement
- has a distinctive lustre
- constructed using plain weave
- usually made from filament yarns
- colour changes when fabric moves
what is the importance of logos to a designer
- they are unique visual symbols that distinguishes a designer from the competition
- they identify a company through specific colours, shapes or fonts and create brand loyalty
- designers work can easily be recognised raising the profile of a brand
- logos can help promote a brand to increase sales
what is the importance of trademarks to a designer
- a logo or specific design can be registered as a trademark shown by TM or r symbols
- used to identify and promote a brand unique to designer
- offers designer protection from other companies copying and reproducing their work
- designers can take legal action against counterfeiters or those who create similar designs
what are the benefits of electronic point of scales for fashion manufactures and retailers
- uses electronic data interchange to communicate information directly to company
- removes need for paper documents such as invoices and product orders
- its a single system at the till point that scans barcodes and processes payments from customers by connecting electronically to different payment methods
- sales information is sent directly to manufacture so production is automatically adjusted to make more of best selling products and stop production of low sales
- stock levels are automatically updated as EPOS sends information to replenish stocks based on product sales
- facilitates JIT production minimising storage and allowing effective cash flow
- sales info is used to design future fashion collections
- keeps customer info for marketing purposes to send them discounts
- garments are manufactured to level of demand eg. sizes so retailers are not left with wasted stock
how does wool enhance the properties of a knitted jumper
- fairly strong but addition of nylon would add to strength making it more hard wearing
-naturally absorbent helping to absorb perspiration although is water repellent due to lanolin - crimp helps fabric keep its shape and makes it warm as traps air to create thermal insulation
- has soft handle
- other fibres are smooth so may counteract wools tendency to irritate skin
- amount of moisture in wool prevents it from being flammable
- short staple fibres of wool will contribute to pilling however other fibres in blend help to minimise bobbling on fabrics surface
how will nylon enhance the properties of a knitted jumper
- nylon is a synthetic non absorbent fibre which will balance with the wool to help regulate body temperature
- can be heat set, and in combination with wool and elastane, it has the ability to hold shape
- its a fairly cool fibre that does not trap air but in combination with wool will create a relatively warm fabric
- will melt in contact with extreme heat but wool prevents it from being a flammable fabric
- prone to build up of static electricity but moisture content in wool reduces this effect
- helps wools tendency to shrink enabling a quicker drying time and making it easier to care for
how do metal fibres enhance the properties of a knitted jumper
- they reflect light providing an interesting visual and colour effect to enhance the fabric
- light reflecting properties add sparkle especially in combination with wool which doesnt have a natural lustre
how will elastane enhance the properties of a knitted jumper
the addition of a small amount of elastane will provide the fabric with stretch and recovery properties
what are the points a designer will need to consider when creating a specification for childrens fancy dress clothing
- fabric enhancement: use of embroidery, dyeing or printing to add colour and pattern
- fabrics: colourful fabrics in line with theme and characters including interesting textures such as satin, lace or sheer fabrics
- novelty effects such as glitter, metallic and neon including features unique to character or theme
- components: decorative components such as trims, ribbons and fringing and functional components suitable for target market such as elastic waist band
- comfort: fabric with stretch that is easy dressing such as jersey or use of elastane
- safety: awareness of fire hazards, including warning labels and use of non flammable fabrics
- accessories: hats, bags and other items appropriate to the theme
- wash care: garment may be required for easy care or spot cleaned
- cost: low fabric cost such as polyester as children grow quickly so may only wear costume a few times
- target market: age appropriate styling
analyse and evaluate the sustainability of lyocell during sourcing
- lyocell is a cellulose based fibre sourced from wood pulp
- the pulp used to make the fibre is mainly sourced from eucalyptus and sometimes from oak and birch trees
- eucalyptus is a fast growing tree that needs no irrigation
- it can easily grow on land that is unsuitable or is not fit for food and farming
- most of raw material is sourced from managed forests where trees are replanted after they are cut down
- unlike many other fibres, lyocell does not require pesticides or fertilisers
- to be environmentally sustainable it must be sourced from managed forests
- however sourcing the material requires heavy machinery that relies on non renewable materials such as coal and oil
analyse and evaluate the sustainability of lyocell during manufacturing
- lyocell is manufactured through a wet spinning process
- the raw material is cut into small chips made into pulp and dissolved by a chemical to make the spinning solution
- the chemical used amide oxide is non toxic
- spinning solution is pushed through spinnerets to make fibre
- lyocell is made in closed loop process: solvents are recovered, purified and reused, creating minimal waste
- lyocell is biodegradable and can fully degrade in 8 days
- its processed in factories where machinery uses fossil fuels and other forms of non renewable energy
analyse and evaluate the sustainability of lyocell during transportation
- lyocell is usually made off shore, mostly in china and asia
- transporting the fibre of fabric has significant impact of environment
- packaging may be plastic or non environmentally stable
- transportation such as lorries, planes and ships use non renewable fossil fuels
- the burning of these fuels releases CO2 emissions contributing to global warming
- oil spills from ships can pollute water ways and cause harm to marine life
- transportation to warehousing and retailers from ports causes further air pollution
outline batch production
- products are made by a team of skilled workers in a factory
- many products are made at the same time in one run or several batches which can range from a few to thousands of items
- items are quality checked at certain points during manufacture
- products are identical to each other
- garments are made in a range of standard sizes
- made on production line in a factory - costs are usually in line with high street retailers
- machine made
outline bespoke production
- products are made by one highly skilled craftsman
- a singular garment or textiles product is usually made only once or as part of a small collection
- usually made with care and to high standard
- products are unique or one off
- garments are made to measure for an individual client
- expensive method of production due to labour costs and high quality materials
- often included hand sewing and finishing
what are the qualities required in fibres used in work trousers on a construction site
- synthetic fibres such as polyester and polyamide provide strength, durability are non absorbent and light weight
- natural fibres such as cotton are strong, breathable and good at absorbing moisture
- fibres such as carbon and kevlar provides strength and high abrasion resistance in areas of wear
- elastomeric fibres provide strength and recovery properties allowing easier movement
- fibre blends will provide specific properties
