Physical Characteristics + Working Properties

Question 1

What does it mean when a fibre is allergenic?

Physical

Answer 1

some fibres can cause minor allergic reactions - due to chemical makeup or applied finishes

Physical

Question 2

How does texture differ between fibres?

Physical

Question 3

How does density of fibres differ?

Physical

Answer 3

• fibres spun ino yarn will have different thicknesses
• fibres woven into cloth will have different densities
• depends on how tightly they’re woven/knitted

Physical

Question 4

Define tensile strength
Example

Working P

Answer 4
