What is olefin you may ask. Polypropylene is the chemical name given to the compound we know as the textile, olefin. Chemically speaking, polypropylene sounds like a complicated process, but is in fact a greener fabric than cotton, wool, silk, or rayon. Olefin, or PP, is a synthetic based polypropylene fabric that was first created in Italy in 1957. Propylene, historically, was burnt off during oil production because it was thought to have no industrial use. Upcycling is a process used to create materials that were once thought to be waste products, but now can be chemically transformed into useful materials. Polypropylene is manufactured by polymerizing propylene compounds to get polypropylene. What does this mean? Simply put, smaller single molecules are combined and linked to form longer chain molecules with repeated structural units. The long chain molecule polypropylene, now in pellet or bead form, is then melted and ran through a machine called a spinneret to link all the molecules together into thread. During the melting process, solution-based dyes must be applied because polypropylene is chemically stain resistant. This means after the thread is made, it will not take a dye or stain if applied after thread form. That is why it is imperative to solution dye or pigment dye your olefin during the melting process. After the spinneret turns the polypropylene into thread, the thread is spun into yarn which is then woven into your desired textile application. Today, the olefin market makes up 16 % of fiber production. Olefin uses no water or land during the production and was once waste material from oil production; making it one of the greenest textiles with the lowest carbon footprint.
