简体中文Polyester fabric is a synthetic fabric made from polyester fibers, which are derived from petroleum. The production process for polyester fabric involves several steps, including:
Polymerization: The first step in producing polyester fabric is to create the raw material, polyester polymer. This is done through a process called polymerization, where the polyester monomers are chemically bonded together to form long chains.
Melt spinning: The next step is to melt the polyester polymer and extrude it through spinnerets, which are tiny holes in a metal plate. The extruded fibers are then cooled and solidified into filaments.
Drawing: The filaments are then drawn through a series of heated rollers to stretch them and align their molecular structure, which increases their strength and durability.
Texturizing: The filaments may also be texturized, which involves crimping and twisting the fibers to give them a more natural, fabric-like appearance.
Weaving or knitting: The filaments are then woven or knitted into fabric using machines. Weaving involves interlacing the fibers in a perpendicular pattern, while knitting involves interlocking loops of yarn.
Finishing: The final step in the production process is to finish the fabric. This may involve processes such as dyeing, printing, or coating the fabric with chemicals to enhance its properties, such as water resistance or flame retardancy.
