Background
The polyester fiber is generally a fiber prepared by melt spinning polyethylene terephthalate (PET), and is a first major variety of the current synthetic fiber with the domestic trade name of terylene. The polyester fiber has higher modulus, is more suitable for blending with cotton and wool in a short fiber form, and the prepared fabric is superior to a pure spinning fiber product in certain aspects. Polyester filaments have also been rapidly developed and differentiated varieties, such as alkali dyeable, anti-pilling and high shrinkage fibres, have begun to be put on the market. Polyester fibers are most widely used in all synthetic fibers and are the most productive fiber varieties due to their superior raw material costs compared to other fiber raw materials (e.g., polyamide, etc.). The polyester fiber has excellent tensile properties, elasticity, light resistance, friction resistance and chemical resistance.
In the production of polyester fibers, a draw false twist texturing machine is one of the most important production equipments. The draw false twist texturing machine, also known as draw texturing machine, stretch texturing machine and texturing machine, is a main equipment for processing polyester fiber filament textured yarn, and it depends on the mechanical action of false twisting (twisting first and untwisting later) to endow thermoplastic synthetic fibers, such as POY and FDY, with elasticity (high elasticity and low elasticity), air permeability, extensibility and high bulkiness, so that the fibers have good weaving performance. Because synthetic fibers have thermal plasticity, after the processes of thermal deformation, cooling, twisting, untwisting, heat setting and the like, single fibers (DTY) solidify the spiral curling characteristic, so the synthetic fibers are called stretch yarns and also called textured yarns.
The texturing hot box is one of important components of the stretching false-twisting texturing machine, and plays a role in heating the protofilament before false twisting.
