Synthesis and Investigation of Polypropylene Random Copolymers Yarn with High Flexibility and Changeable Length

Structure of yarn has been investigated and base textures have been presented. Yarns have been improved by adding propylene to it. Propylene has many properties. Propylene yarn has good tensile strength and flexibility. Polypropylene random copolymers hardness and temperature stability. Here flexibility of polypropylene random copolymer has been investigated. Also, Commercial grades are available in a variety of molecular weight distributions, and co-monomer types as well as contents and additives. Enhanced physical properties allow polypropylene to be the core material in most demanding applications such as films, fibers, tapes, sheets, thermoforming, injections, and blow molding.
