process in order to orient the molecular structure fully and optimise the
yarn’s tensile properties.
PET:
Pick:
Pill, pilling:
PLA:
Polyamide:
Polylactic acid:
Polymer:
polyethylene terephthalate, the most common form of polyester.
a single weft thread in a woven fabric.
the entangling of fibres during washing, dry cleaning, testing or in wear to
form balls or pills which stand proud of the surface of a fabric and which are
of such density that light will not pass through them (so that they cast a
shadow).
polylactic acid, a synthetic polymer formed from plant-based material and
used as the starting material for a new range of melt spun synthetic fibres,
including Ingeo from Cargill Dow.
another word for nylon.
see PLA.
a long molecule made up from many smaller repeat molecules; the following
polymers are the main ones used to make synthetic fibres:

polyacrylic;
polyamide (nylon);

polyurethane.
Polymerisation:
POY:
Prepolymer:
Push-pull fabrics:

Retention:
Rip stop:
the process of linking small chemical units together to form larger molecules.
see partially oriented yarn.
a polymer of relatively low molecular weight—usually intermediate between
that of the monomer and the final polymer or resin—which may be mixed
with compounding additives and which is capable of being hardened by
further polymerisation during or after a forming process.
bicomponent fabrics composed of a non-absorbent hydrophobic material,
usually polyester, on the inside (worn next to the skin) and an absorbent
hydrophilic material, usually nylon, on the outside.
a term used to describe fibres made from regenerated cellulose (see also
viscose, modal and acetate).
one of three types of production process used to make elastane (the other two
being dry spinning and wet spinning) in which fibres are formed through
a chemical reaction, and polymerisation and formation of filaments occur
simultaneously as the prepolymer is extruded in a reagent bath.
the weight of fluid remaining after a freely swollen fibre, yarn or fabric is
subjected to a pressure of 0.5 lb/in 2 .
a lightweight woven fabric containing corded yarns spaced at regular
