In common spills and stains such as coffee, sodas, foodstuffs and medicines in health care environments, type 6 nylon stains more readily than type 6,6 nylon whether solution dyed or conventionally dyed with equal fiber engineering. DuPont is the major manufacturer of type 6,6 nylon. Type 6,6 nylon is hard, abrasion resistant under conditions of ground-in dirt, resilient and lightfast. Additionally, due to the unique molecular structure of type 6,6 nylon, it is more resistant to stains than any type 6 nylon. O Olefin Also known as polypropylene.
Olefins are less expensive than nylons.
Olefin is the lightest weight fiber and has good bulk and cover. However, the polymer base creates a soft fiber which has poorer resiliency than nylon and poorer texture retention. Ozone fading The fading of color from a dyed or pigmented fiber caused by atmospheric contaminants of ozone or oxides of nitrogen. P Pigment Highly colored insoluble substance used to impart color to other materials. Sometimes called the face or nap.
