PRODUCTION
1. spandex covered yarn: rewinding - rewinding truck -spandex -spandex band machine - Inspection - packing - coming out
2. The spandex filament is led out from the core filament supply bobbin by the core filament input roller, and then passes through the hollow spindle. The hollow spindle rotates driven by the Dragon belt.The wrapped polyester filament wrapped on it is led out and twisted due to its rotation, and coated on the spandex core filament penetrated from the hollow spindle to form a polyester spandex covered yarn. The covered yarn is pulled and wound on the winding bobbin by the wire guide shaft.
Polyester spandex covered yarn is an elastic composite yarn formed by taking spandex filament with a certain drafting multiple as the core and wrapping the polyester filament spirally outside the core filament through the covering process. The composite yarn not only has the characteristics of wrapped polyester, but also has the good elasticity and recovery performance of spandex, which makes up for the defect of single component filament.
3.The mechanicallyspandex covered yarn is that the outer fiber filament is continuously rotated and wound on the core spandex drawn at a uniform speed. It is twisted and has a twist. Its main feature is that the fabric style is flat and neat.
In the rewinding workshop, the large DTY is first transformed into a small DTY through the rewinding step, which is convenient for use in the wrapping workshop. In the wrapping workshop, the small DTY is placed on the machine, the spandex at the bottom is used as the core wire, and the DTY filament is wound on the spandex to finally form the spandex covered yarn.
