What are the man made fibres
Regeharated and synthetic
3 of 36
What is a filament fibre
One long continuous length (all synthetic and silk)
4 of 36
what is a staple fibre
It is short and has to be spun together to make a yarn (these are from natural fibres)
5 of 36
Issues to include:
Social, cultural, ethical, environmental
6 of 36
What is a blended fibre?
A combination of two or more different fibres spun together when the yarn is made An example of this is Cotton and Polyester This is because it would be lightweight, poor absorber, elastic, quick drying and crease resistant
7 of 36
What is a mixed fibre?
A mixed fibre is where one type of yarn is mixed with at least one other in the fabric production A common example is the mix of cotton yarns with lycra to give extra strength and comfort
8 of 36
What are the main reasons for blended and mixed fibres?
To improve the appearance of a fabric To improve the quality of a fabric so that it is more durable stronger and easy to care for To improve the handle of a fabric so that drapes better, is easier to sew and can keeps its shape well

Blended = combination of fibres
10 of 36
mixed = combination of yarns
11 of 36
What are the three main types of fabric constructions?
Woven Knitted Non-woven (made directly from fibres, glued, bonded, needle punched)
12 of 36
Warp yarns run vertically Weft yarns run horizontally The selvedge is the side that doesn’t fray Computer aided manufacture
13 of 36
Key characteristics of weaving?
Edges don’t fray unless cut Strongest along the straight grain of fabric Don’t stretch unless cut on bias or elastain has been woven in
14 of 36
What are the two ways of producing non- wovens?
felted, bonded
15 of 36
What types of fibres are used in felting?
Short staple fibres
16 of 36
What are the three methods of making bonded fabrics?
Dry laid Wet laid Direct spun
17 of 36
What are felted and bonded fabrics used for?
hats, jackets, coats, Cover of snooker table
18 of 36
What are the properties of felted and bonded fabrics?
Not strong, Do not fray, Cheap to produce, Weaker when wet
19 of 36
What are laminated fabrics?
They are made by bonding two or more fabrics together.
20 of 36
What are the features of wool felt?
Good insulators, Good crease resistant, Has no grain
21 of 36
What are the features of needle felt?
Does not fray, Light weight, More elastic
22 of 36
What is knitting?
Is made from the interlocking of loops using one or more yarns
23 of 36
Why are knitted fabrics warm?
The yarns loops trap air to provide insulation

32 of 36
What is Anthropometrics?
The study of body sizes; there are standards for men, women, children, hands, feet and heads
33 of 36
What is the bias?
The weave of the fabric which is parallel to the selvedge. The straight grain can also follow the weft threads.
34 of 36
What are the responsibility's of health and safety officers?
Display warning notices, Carry out risk assessments, Organise safety training , Ensure that machinery, equipment and tools are stored safely, Check that the environment is safe with clean and tidy work areas
