Fios de poliéster
Polyest Wire is an important variety in synthetic fibers, which is the name of polyester fiber trade. It is the fiber polymer based on pure terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) as raw materials by esterification or ester exchange and polycondensation reaction — polyethylene terephthalate (PET).It means it is fibers made by spinning and post-treatment. Moreover, Ningbo Judin Special Monofilament Co., Ltd uses high quality raw materials from world famous suppliers in order to produce stronger products, such as DuPont (the USA), Honeywell (the USA), Mitsubishi (Japan), Basf (Germany) and CPCC (China).
According to Polyest Wire, you can cut a ray of artificial silk to do the test, pulling hard, then relaxing and finding the embroidery line will not shrink. In addition, after pulling the polyester silk, once relaxed, it will return to the original length. By this way, it sometimes leads to wrinkles. So in line tension adjustment aspect, it needs more accurately.
There are two important strategies of Polyest Wire:
DTY Draw texturing yarn is also known as polyester low elastic yarn. It is a kind of finished yarn in a machine for continuous or simultaneous stretching and deformation .
FDY Fully drawn yarn has nothing to do with production process, but widely circulated. It is a one-step process code of spinning craftwork, which can use low-speed spinning, high-speed stretch winding. These two processes are completed in a spinning stretch joint machine. This production line production costs low, and the finished products have stable quality , less hair loss, dyeing uniformity.
