Why Do Designers Analyse Sales Figures?
To find out:
- What is selling well,
- To show seasonal differences,
- To assist with fabric choices,
- To plan new designs.
- To review patterns/styles and colour choices
What Areas Do Designers Look At When Researching N
Designers Look at:
- Product shape and size,
- The different fabrics used,
- What decorative techniques have been used,
- Tried and tested methods of construction
- Types and hems used
Applique is a Suitable Technique Because:
It is strong and adds strength to the fabric base
You can easily colour large areas,
It adds texture,
It can be produced automatically using CAM,
The imagery used can be stylistic.
Why Blend Fibres? (Fibre Type Polyester/Cotton)
Polyester is strong but not absorbent,
It does not crease,
When blended with cotton it reduces the overall absorbency so it makes it quicker to dry and less likely to shrink,
Polyester adds strength and allows the fabric to be heat set meaning pleats can be added,
Poly/Cotton is versatile, lightweight, durable, wrinkle resistant and retains coolness.
Computers Can Be Used To Help Manufacturing - How?
Pattern pieces can be layed out to minimise waste, and save time
The pattern layout can be saved so it can be re-used, or modified at a later date
Automated Lazer/cutter is more accurate than cutting by hand,
Using a computer is safe and quicker than doing it manually,
What is TQM?
TQM is Total Quality Management.
- It is used in in the planning process
- Used in quality systems to make sure a textile product fulfils agreed standards.
- TQM is used constantly and continuously to improve the manufacture and make things better
Why do designers create a prototype?
- test accuracy of size / shape of product,
- find out how shaping might be achieved,
- check on methods of manufacture,
- consider a range of materials which will help achieve shape,
- iron out (work out) potential (possible) manufacturing problems,
- help plan bulk manufacture in terms of equipment, labour requirements, costings
What is a prototype?
A prototype is a trail of a product – a sample or a mock up.
It is a model of a design in a 3D format.
You can prototype aspects (parts) of products such as sleeves, seams/hems and even techniques to evaluate the usefulness of the construction/technique
Why is sub assembly used in industrial manufacture
- specialist machines / workers may be used,
- checked for faults,
- cost effective, lspecialist components available.
What are the dangers of using an industrial sewing
- Stitching fingers,
- Needle breakage and being hit/flicked in the eye,
- Bumped, bruised or cut by the sewing machine screw as the needle is moving up and down,
- Burns by the light bulb
- and inhalation of textile dust.
How can these dangers be reduced or elimated (got rid of) ?
- use of guards on machines,
- dust extractors,
- training of staff,
- regular safety and maintenance checks,
- emergency stop buttons,
- regular breaks so concentration is not lost.
What are smart materials?
Smart materials respond to differences in temperature or light and change in some way. They are called “smart” because they sense conditions in their environment and respond to those conditions. Smart materials appear to ‘think’ and some have ‘memory’ as they revert back to their original state.
Developments of smart materials have been made to create to develop a sense of wellbeing. They have anti-stress or calm inducing properties. Smart materials are also used in medical use. Fabrics can be encapsulated with substances required by the body or antiseptics.
Some people suffer with allergies so Allergy control fabrics have been created these are clothing, linens, towels and carpets.
Many synthetic fibres have moisture management properties. Softswitch technology is currently under development to produce wearable electronics.
FASTSKIN (speedo) is an example of a smart material
What is JIT and how is it used in Textile manufact
JIT standrads for "Just in Time"
Manufacturers use ICT to help plan ordering of materials and components.
JIT ensures they arrive "Just in Time" for production.
Its a complex system and requires careful planning between suppliers and manufacturers.
JIT is often used in QRM (Quick Response Manufacturing) where goods are made quickly to exact quanties needed to meet demand.
Why is JIT used in Combination with QRM?
JIT is used in combination with QRM because:
- it reduces stockpiles of raw materials waiting to be used
- it is less likely that stock can be damaged in storage or lost
- it reduces the space needed for keeping stock
- it reduces the levels of finished goods put into stock waiting to be sold
- it cuts the cost of money in stock.
QRM - what is this?
QRM stands for Quick Response Manufacturing.
- it is a method of production
- uses self organised and multi skilled teams of employees, who are reponsible for QUALITY and Quantity of output.
- QRM is used in Batch production, where quick reponse is needed to demand
- QRM is developed through ICT
- QRM enables fast electronic links between retailers and manufacturers
- product sale information is collected via the EPOS (Electronic Point of Sales)
- It can collect/calculate stock levels
- orders can be sent to the manufacturer for quick delivery of fast selling items
- it highlights fast selling items - so manufacturers can produce batches of products that responds to consumers needs and demand.
Nano Technology – what is it?
Nano-fibres are very fine fibres (about 1% of the width of a human hair) which can be engineered for different end uses.
These fibres are extremely lightweight, smooth and fine, but also very strong.
They are typically produced from carbon or ceramic materials, spun and collected in non-woven felt-like sheets.
They can be added to a base of other fibres such as cotton, wool, polyester.
Potential uses include self-cleaning fabrics used for underwear, work clothing, sportswear, fabrics used for catering and hospital applications, military applications such as lightweight bullet proof clothing, energy saving applications such as panels for computer displays, and a variety of filters.
Nano technology continued......
It is possible to spray a nano-fibre on to the body to give a seamless skin covering.
Because these fibres are so fine, a large area of fabric can be folded so it takes up a very small space. The sheets of nano-fibre can be used as breathable membranes which allow body moisture and air to pass through but prevent larger water molecules and other particles from passing through, hence their potential use in sportswear and protective wear.
- Use ICT in QRM enables JIT (Just in Time) ordering
QRM is cost effective because
- uses effiecient multi skilled workforce toincrease productivity
- reduces the levels of finished goods put into stock. ie. waiting to be sold
- reduces space needed for keeping goods
- cuts cost of tying money up in stock
