Title: Textile Fiber-Forming Polymers Description: This learning object defines the basic fiber-forming unit and the reactions by which monomers react to form polymers. Bonet Aracil, MA. (2013). Textile Fiber-Forming Polymers. http://hdl.handle.net/10251/29132 Automatic description: This video, from the Department of Textile and Paper Engineering at the Polytechnic University of Valencia, explains textile fiber-forming polymers and the processes for obtaining them. It defines what a polymer is and how it is produced through polymerization reactions, highlighting its importance in the transformation of polymers into textile fibers. It illustrates that both plastic objects and textile fibers can originate from the same base material, known as chips or pellets. The characteristics of polymers and the importance of molecular weight in the creation of fibers are detailed. A distinction is made between homopolymers (chains of a single type of monomer) and copolymers (chains of different monomers), noting that they can be linear or branched, and mentioning the influence of the degree of polymerization on fiber properties. In addition, the two main polymerization reactions are addressed: polyaddition and polycondensation, explaining the process of each and the generation of byproducts such as water or carbon dioxide. Examples are offered of polymers such as cellulose, acrylic proteins, polyester, and polyamides, which give rise to fibers such as cotton, wool, acrylics, and polyester. Finally, as final considerations, the importance of raw material selection and the monomer mixing and activation processes for the formation of polymers and macromolecules that will later be transformed into fibers are emphasized. The presentation concludes by thanking the audience for their attention.
