1.1 materials and applications Flashcards
why is choosing the right textiles materials for products complex
because of the interplay between fibre, yarn, construction method and finishing processes
what will the final choice of fabric mainly be influenced by
product function and the materials physical and aesthetic properties
what is a fibre
a fine hair like thread
what is yarn
a long continuous length of twisted fibres used in the construction of woven and knitted fabrics
what is a finishing process
an additional process to improve the appearance and/or performance of a fabric
what are aesthetics
the beauty or tastefulness of the look of a product, and how attractive it is to the consumer
what is tensile strength
the ability to resist breaking under tension
what is abrasion tension
the ability to resist surface wear caused by rubbing contact with another material
what is elasticity ( crease resistance )
the ability to be deformed and then return to the original shape when the force is removed
what is absorbency
the ability to absorb and retain liquid
what is easy care
the ability to maintain optimum appearance with the minimum effort of laundering
what is colour fastness
the ability to retain dye during the manufacturing process and when washed or exposed to sunlight
what is electrostatic charge
the ability for static electricity to develop in fibres under exceptionally dry conditions
what is thermal insulation
the ability to trap air, preventing the transfer of heat through the material
what is corrosive solvent resistance
the ability to withstand attack and decay from substances such as chlorine bleach
what is microorganism and insect resistance
the ability to withstand attack and decay from organisms such as bacteria and moths
what is flammability
the ability to burn or ignite, causing fire or combustion
what is thermoplasticity
the ability to become pliable and mouldable when heated, enabling textures and creases to be set and retained once cooled
what is formability
the ability to manipulate and deform fabrics without damaging them
what is handle
evaluates how a fabric behaves, performs or feels when touched
what is drape
the term used to describe the way a fabric hangs under its own weight
what is lustre
refers to a textile materials ability to reflect light from its surface so it appears glossy
