Olefin fibre
Also known as polypropylene. It is used for molded
items, sheets, films and fibres. Made from a by-product of gasoline
refining, olefin has one ingredient: propylene. Since propylene is
widely available at a comparatively lower cost than nylon base ingredients,
olefin is less expensive than nylon. Olefin does not accept aqueous-based
dyes or stains. Colour is added in the manufacturing process in the
form of pigment. Printable modifications are available but not extensively
used. Olefin is a lightweight fibre and can have good bulk and cover.
However, the polymer base creates a soft fibre which has poor resiliency,
a lower melting point and poor texture retention as compared to nylon.
The carpet fibre is available as bulked continuous filament yarn.
Only when budget is the main consideration, lower life expectancy
is anticipated, and long-term appearance retention is not a priority,
olefin can be considered.
