Production Methods and Main Application of Full Dull Yarn

Polyester yarn is one of the most frequently utilized synthetic fibers used in textile and apparel production. Polyester has many advantages over natural fibers like cotton or wool, such as high tenacity, low shrinkage, and increased heat resistance. Producing yarn can be harmful to the environment, so efforts have been undertaken to create more eco-friendly alternatives like Full Dull Yarn with its matte, non-shiny appearance. This type of yarn is created by adding a specific chemical to polyester during production, creating a rough surface that scatters light instead of reflecting at it and thus giving the yarn an overall muted appearance.
Full Dull Yarn is a type of polyester filament yarn that features a subdued luster. Produced by using special chemicals during spinning that create rough surface bumps on its yarn threads to avoid reflecting light onto them, full dull yarn provides a subdued look ideal for certain garments and fabrics, in addition to being very durable and abrasion resistant making it suitable for various applications.
Nylon POY (Polyolefin Olefin Yarn) is the original form of Nylon yarn produced directly from Nylon chips, spun into yarn by spinning. From there it can be further twisted and drawn to create Drawn Textured Yarn (DTY). DTY yarn can then be combined with other yarns to create fabric of various types and specifications; its surface finishes may range from semi-dull to full-dull and Bright, making this an excellent base yarn with which to dye fabrics with specific color combinations.
The production method of the present invention achieves the following technical results: the full-dull polyester filament produced is functional and of consistent quality, featuring a line density of 124dtex, fracture strength of 2.29cN/dtex fracture resistance, 126.5 percent elongation at break and unevenness rate of 1.52% in yarn production. Furthermore, this filament features soft handling characteristics suitable for various textile and apparel uses.
Polyester FDY yarns are used extensively for weaving, knitting, braiding, and narrow weaving applications as well as technical applications. Made of Polyethylene Terephthalate Acid (PTA) combined with Mono Ethylene Glycol (MEG), Barmag Wings FDY lines extrude speed directly from the chip into filament yarns at high speed ensuring maximum quality and speed. Polyester FDY comes in three lusters: Bright, Semi-Dull, and Full-Dull with round being the most commonly seen cross-section; other cross-sections include flat and trilobal shapes as well. Finally, all our Polyester FDY yarns can be dyed to various shades!
