Polypropylene is a major polymer used in nonwovens, with over 50% usedfor diapers or sanitary products where it is treated to absorb water rather than naturally repelling water. Other interesting non-woven uses include filters for air, gas, and liquids in which the fibers can be formed into sheets or webs that can be pleated to form cartridges or layers that filter in various efficiencies in the 0.5 to 30 micrometer range. Such applications could be seen in the house as water filters or air-conditioning-type filters. The high surface area and naturally oleophilic polypropylene sticker labels are ideal absorbers of oil spills with the familiar floating barriers near oil spills on rivers.

In New Zealand, in the US military, and elsewhere, polypropylene, or 'polypro', has been used for the fabrication of cold-weather base sticker labels, such as long-sleeve shirts or long underwear. Polypropylene is also used in warm-weather gear such as some Under Armor clothing, which can easily transport sweat away from the skin. Although polypropylene clothes are not easily flammable, they can melt, which may result in severe burns if the service member is involved in an explosion or fire of any kind. Polypropylene undergarments are known for retaining body odors which are then difficult to remove. The current generation of polyester does not have this disadvantage.

Thanks to its specific weight, polypropylene yarn is the lightest fiber of all synthetic and natural fibers. Producers gain economic and ecological advantages when producing fabrics and clothes out ofsticker labels. Final users gain more comfort because the garments are lighter. This enables them to give better performance during their activities and gives them the freedom of movement. For example, if they hike, they have less weight to carry. Polypropylene yarn has very good insulation properties. Its water absorption is almost nil. Fabric made of polypropylene yarn transports humidity to the outside or to another absorbent layer from where it gradually evaporates.
