Types Of Polyester Yarns

Polyester Filament Yarns (PFY) or filament polyester yarn, are highly sought-after yarns derived from PET polyester on the global market. Polyethylene Terephthalate is another name for PET Polyester. In the modern fiber manufacturing industry, these yarns are widely used. PFY is powerful and captivating.

Both multifilament and monofilament versions are available. PFY offers a variety of qualities. Light textiles such as organdie and voile are made with high tenacity PFY, while ordinary tenacity PFY is utilized for heavier materials. The high tenacity or duller type of PFY is used to produce lingerie, whereas the low tenacity or duller version is used to make blouses and shirts.

Spun yarns are a popular Polyester yarn type made from PCDT or chopped PET. Spun yarns are made by spinning polyester fibres together. Knitting and weaving are two of the most common uses for such yarns. Consumer fabrics, embroideries, and home furnishings are all made with spun yarn.

Polyester POY is twisted and drawn to make textured yarns. The PET multifilament was utilized to make it.

Our Polyester Yarn Stock

There are both low shrink and normal shrinkage polyester and nylon yarns starting at Dtex 78 running through Dtex 140, 225, 280, 420, 550, 830, 1100, 1670, 2200. Some counts are available in dope dyed black. We can also do dope dyed yarns in specific clients’ own shades, with 1 tonne minimum order quantities in various counts.

Difference between High Tenacity Polyester and Regular Polyester Filament Yarns

Polyester is the most used man-made textile fibre worldwide. It is generally inexpensive and can be adapted in processing to change different aspects. It can be texturised to create bulk. It can be extruded as a dull or as a bright fibre. 

It can be extruded with additives included in the extrusion mix, i.e. anti static masterbatch components or masterbatch colour components for example. High tenacity yarns are a specific refinement which moves polyester yarn into technical industrial application areas.

High-Tenacity Polyester Yarn

To produce high tenacity polyester yarn starts with melting the polyester polymer at around 265 degrees centigrade and then spinning to produce continuous filaments. In the case of a Decitex 1100/192 high tenacity polyester yarn, this means 192 filaments are produced at the same time. 

The Decitex 1100 refers to the weight of the yarn (decitex = weight in grams of 10,000 metres) so every 1.1 kilos of weight produced is 10 kilometres in yarn length. It is the cooling process and the stretching methods used during this process that determine the orientation and crystallisation of the polymer chains. 

The manipulation of stretching and cooling can lead to higher properties in tenacity. For example, the breaking strength of a typical Dtex 1100 high tenacity polyester yarn is around 75 to 90 newtons, but as in all textile processes we often need other things and there are trade-offs. For many textile processes that use industrial polyester yarns, the elongation of the yarn can be a crucial factor in processing, in addition to the amount of shrinkage in the yarn.

Hot air shrinkage is normally measured for 2 minutes at 180 degrees centigrade and levels can range from as low as 1-3% suitable for hoses where stability is required, to around 12-15% where shrinking the fabric to condense it has benefits, such as sailcloth where condensing the fabric makes it less easy for air to pass through the sail.

The elongation of the yarn can also be an important point. The elongation is a consideration in processing but also important in end uses such as slings and ropes. Normally, specification sheets for high tenacity polyester yarn will reference the elongation at break figure (normally between 10 and 20%) but for many processes the elongation at a specific load amount can be more relevant.

High Tenacity Polyester Yarn, a premium offering at SageZander, embodies the pinnacle of textile innovation. Known for its exceptional strength and durability, this yarn is expertly engineered to endure the most demanding applications. Our high tenacity polyester yarn stands out for its remarkable tensile strength, ensuring longevity and reliability in various industries, including automotive, marine, and outdoor fabrics. Its resistance to abrasion and UV damage makes it an ideal choice for products that face harsh environmental conditions. At SageZander, we are committed to providing our clients with yarns that not only meet but exceed industry standards, ensuring that every product made with our high tenacity polyester yarn delivers unparalleled performance and quality.

Regular Polyester Filament Yarns

Compared to regular polyester yarns, which are more apparel focused, high tenacity yarns are generally suited toward various uses. Nets and nettings for sport, cargo and fishing generally use the higher dtex yarns like Dtex 1100 and Dtex 2200. Tie down straps in narrow fabrics, strapping can be anywhere in the range Dtex 280 to Dtex 4400 generally.

Conveyor belt fabrics, hoses for high pressure hoses and hose reinforcement, geotextile and geogrid fabrics can range between Dtex 5500 to Dtex 1670. Ropes generally use the heavier counts and our solution dyed also known as dope dyed coloured high tenacity polyester yarns are used here. 

Rubber reinforced fabrics and dipped cords often need special finishes on the yarn to get good adhesion and use yarns in the Dtex 1100 to Dtex 2200 area. Other areas include slings for lifting, tarpaulin fabrics and fabrics for coating, sail cloths, seat belts, fabrics for filtration and harnesses. Sewing thread manufacturing can often use lower Dtex yarn down to Dtex 78, often 2 or 3 plied.

Frequently Asked Questions

Polyester Yarn is one of the finest and most common synthetic yarns that are used for various purposes.  Synthetic fibers using polyester have high water, wind and environmental resistance compared to plant-derived fibers. They are less fire-resistant and can melt when ignited. Natural polyesters could have played a significant role in the origins of life.

There are three types of Polyester yarns:

  • Polyester Filament Yarns
  • Spun Yarns
  • Textured Yarns

Polyester (polyethylene terephthalate) is derived from a chemical reaction involving petroleum, air, and water. This artificial fiber is comprised of purified terephthalic acid (PTA) and monotheluene glycol (MEG). 

Polyester is a “melt spun” fiber, which means that it is heated, extruded through spinnerets, and cooled upon contact with the air. From there it is loosely wound around cylinders. The fibers are then hot stretched until they are about five times their original length in order to decrease their width. The fiber is then wound onto cones as filaments or is crimped and then is cut into staple lengths.

Polyester filament yarns are used in knitting & weaving to make polyester fabrics such as consumer fabrics and home furnishing like curtains, bed sheets, bed spreads and draperies. Polyester high tenacity industrial yarns can be used to make ropes, conveyor belts, safety belts & tire fabric. Polyester Staple Fiber is mainly used as fiber fills to stuff pillows, cushion, sofa & beddings. 

Polyester Fiber has a melting point of around 295°C (482°F).
