Industrial manufacture Flashcards
What do you look for in a quality control check?
check materials when they arrive at factory: is it the right quantity, colour, look for faults, fabric width and dimensional stability
How are quality control checks carried out?
spot or randomly check in the production process according to the manufacturing specification- look at seam allowance, stitch length, correct components and check against end sample to make sure it looks right
Define quality assurance
quality is assured through designing and planning to make sure the product is consistently the same every time it is made- use of prototyping, sampling or modelling
Mass production
towels, socks, yarns
Batch production
highstreet clothing
One off production
wedding dress, costumes etc
Pos and neg of Batch
Pos= If something goes wrong, eg. doesn't sell well or stock is lost/damaged, isn't too much of a loss Neg= Run out of stock very quickly
pos and neg of mass
pos= cheap, fast neg= can be poor quality
pos and neg of one off
pos= unique, fits perfectly neg= expensive and time consuming
Sub assembly
used to pre manufacture certain parts of a product and then join together - speeds up production process or because it requires specialist equipment like labels or machine embroidery
Just In Time
materials arrive at the factory just in time to save storage space which makes it cheaper, BUT can cause serious problems if late
why do products have a lining
makes it look luxurious, hides seams, adds texture/ warmth, prevent material from ‘sticking’ to tights for example
Iron on interfacing
Eg. Bondaweb- put in cuffs and collars to stiffen them and add stability, craft purposes like applique, makes sewing easier, make product look neater
examples of health and safety
Hair ties back, chainmail gloves on cutting equipment
Regular safeguards used in industry
regular staff training, machine maintenance, correct safety clothing

Definition of Smart fabrics
Smart CHANGES IN RESPONSE TO ITS ENVIRONMENT
Examples of smart finishes
thermochromic, photochromic and pressure (scratch and sniff) either sprayed on as a finish or added as a smart pigment to fabric paint or dye
Microencapsulation
Different micro-capsules embedded in the fibre or fabric
gives off an aromatic scent
can reduce body odour
can provide vitamins or reduce skin irritation
Examples of modern fabrics and fibres
Kevlar (bulletproof), Gpretex (rain and water proof), fastskin (mimics sharkskin)
Nanotechnology
ceramic fibres that a very strong (kevlar) and can be mixed together to make materials- so small they cannot be seen and therefore not woven
Microfibres
100X smaller than human hair and used for cleaning cloths and performance sportswear
