Olefin Fiber to Ozone Fading

Oo

Olefin Fiber
A fiber made from a by-product of gasoline refining, consisting of 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 water-based dyes or stains. Color is added in the manufacturing process in the form of pigment. Olefin is a lightweight fiber and can have good bulk and cover. However, the polymer base creates a soft fiber which has poor resiliency, a lower melting point and poor texture retention as compared to nylon. The carpet fiber 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.

Optimum Twist
The term used to describe the amount of twist that gives the maximum breaking strength or the maximum bulk of a carpet.

Ozone Fading
The fading of color from a dyed or pigmented fiber caused by atmospheric contaminants of ozone.
