2.1 - 2.4 - 2.8 Flashcards
Points about ‘Functionality’ - application or use, ease of working
Property making it easy to use = machine washable
Handle: soft handle eg. Silk
Absorbancy: natural fibres = easier to dye
Insulators: wool, knitted = pockets of air =warmer
Strength: firefighter bulletproof (protecting), woven
Fibre content
Construction method
Weight: summer - lightweight
winter - not lightweight
Flammability: resistant to chemical/biological attack = natural resistance, humidity
Points about ‘environmental factors’ - recyclable/reused materials
Cotton, silk, wool
Less oil extraction
Recycling = less energy
Reuce amount of clothes going to landfill = reduce carbon footprint
CIRCULAR ECONOMY - raw material = design = retail = consumption = collection = recycling = design….. Etc. Etc
Points about ‘aesthetics’ - surface finish, texture colour
Not priority for protection
Customer appeal
Visability (firefighters)
Individuality
Points about ‘ethical factors’, purchased from ethical sources
Supporting social factors, cultural and environmental
Items not made ethical
Fair trade = fair salary
Points about ‘social factors’, social responsibility
Individuals and companies must act in the best interests of their environment and society as a whole
Safe working conditions = proper equipment usage, lighting, injury?, chemicals?
Fair wages/pay
Consumer = aesthetic, functionality, cost - having to buy cheaper clothing but it doesn’t last long
Points about ‘cultural factors’, sensitive to cultural influences
Names - language barrier? Lack of understanding Culturally appropriate clothing Colour Symbols Imagery Sound of foreign word
Points about ‘cost’, bulk buying
Unit price decreases the more units you buy
Storage issues/cost of storage space
Having too much and done have a use for it
Points about ‘availability’, ease of sourcing/purchase
Widely available =cheaper =quick to order and receive material =easy to get hold of
More specialised - take time to find supplier - more expensive
Non - standard size material - having to find a manufacturer to make your requirements - takes time to make - costs more to cover for extra time taken
What is reeling?
Unwinding threads from cocoons
What is polymerisation?
Making chemicals into polymers
What is throwing?
Twisting the filaments
What is carding?
Brushing to straighten the fibres
What is cleaning?
Removing dirt/grease
What is classing?
Grading by quality
What is degumming?
Removing the stiff gum
What is spinning?
Twisting fibres
Don’t forget shearing!!!!
Advantages of weaving
String along the grain, closer the weave = stronger the fabric
Disadvantages of weaving
Fray when cut, lack elasticity
What is the process if weaving?
- Shedding -
Seaprating the warp into upper and lower sheds - Picking -
Putting through the weft. Here using a shuttle. Other types of machines :air jet, water jet, rapier. - Beating -
Pushing new weft to the fell of the cloth - Let off-
Delivers warp to weaving area - Take off-
Winds away fabric from weaving area onto a roller
How do patterns or templates aid production?
Accuracy:
Already has refernce points
Consistency when making several
How do patterns or tan plates aid production?
Quality control:
Refernce points are in the correct place - notches and darts/Taylor tacks = for matching up
Standardised
Lay plan - economically on fabric = minimise waste = save fabric = save money = maximise profits
To check that everything is up to a standard - so you can sell it
Good quality products = good reputation = returning customers
Hwo do patterns or templates aid production?
Speed:
Not having to draft your own pattern
Not having to find dart points etc, etc…
Describe one method of ‘qualify control’ that is used when making prototype products
Use a ruler to check that the seam allowance is the same around the edge within tolerance
Checks zips and fastening are inserted correctly and work
Accuracy of cutting, or a garment won’t fit
Check it is in the grain, so it will drape properly
