Question 3
Question
Twill weave is the simplest weave
Question 4
Question
With Twill weave the weft yarn goes over four or more warp threads and under one.
Question 5

Plain weave is the cheapest weave to produce and is used to make lots of fabrics especially cotton based ones.
Question 6
Question
Non woven fabrics are layers of fibres held together by bonding or felting.
Question 7
Question
Non woven fibres fray and there is a lot of waste when cutting
Question 8
Question
Bonded fabrics are made by combining pressure, moisture and heat to interlock a mat of fibres.
Question 9
Question
Felted fabrics are made by combining pressure, moisture and heat to interlock a mat of fibres.
Question 10
Question
Non woven fabrics are very strong and have good stretch
Question 11
Question
Twill weave is stronger and drapes better than plain weave.
Question 12
Question

Question 13
Question
Weft knitted fabrics have yarns that run up the fabric
Question 14
