fabric construction

fabric construction

the way a fabric has been made - for example, knitted or woven

warp

yarns that run along the length of fabric

weft

yarns that run across the fabric

straight grain

indicates the strength of the fabric in line with the warp yarns

seveledge

the sealed edge of the fabric

applique

stitching different shaped pieces of fabric in a particular design onto a different base fabric

function

what a product will do and how it will work

fabric specification

a list of guidlines used by designers to ensure the correct fabric is used for a product

handle

the level of comfort against the skin

absorbent

a fibre’s ability to suck up moisture

drape

how a fabric hangs, flows when handled

monomer

a molecule that can be bonded to others to form a polymer

filament

a very fine slender thread

lamination

process of joining materials together with heat or adhesive

hydrophilic membrane

ability to repel and release moisture

quilting

a process of layering three materials together and stitching through to improve its characteristics

pesticides

chemicals used to kill or suppress pests that destroy vegetation and crops

ecosystem

the natural and deliberate balance of plant life, soill and animals that live interdependent lives

insecticides

chemicals used to kill or suppress insects that destroy vegetation and crops

finite rescources

non-renewable sources that cannot be replaced in a sufficient timeframe to allow further human consumption

recyclable

a material suitable for processing using tertiary recyling methods

biodiversity

the balance of many different living creatures living side by side in a particular habitat

fast fashion

a recent trend involving quick transfer of new collections from the catwalk into stores. Fast fashion is often on trend, low quality and low in price

throw away culture

consumers do not feel the need to keep clothes any longer in fashion and happily dispose of it

biodegradable

the ability of a material, substance or object to break down naturally in the environment through the action of microorganisms, thereby avoiding polution

thermoforming fibre

a synthetic fibre that can become plastic when heated and harden on cooling - a process that can be repeated
