Our Polyester Yarn Stock
There are both low shrink and normal shrinkage polyester 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.
There are also regular tenacity items such as Dtex 330 dope dyed black available in our stock. SageZander can also provide a wide range of other polyester yarn stock including Tairyfil Carbon fibre yarn, Tintoria Sala, TAY and more!
Where We Supply Polyester Yarn
Our High Tenacity Polyester Yarns are sourced both within Europe and from the Asian market. The partners that we select to buy from and work with in these markets are reliable. Please contact us for specification sheets, pricing and availability.
SageZander can supply Dyed FR (flame retardant) continuous filament textured and flat twisted polyester yarns and regular polyester suitable for weavers in counts starting at Dtex 56 up to Dtex 900. These are suited towards upholstery, curtain label and tie weavers.
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.
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 grammes 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 uses industrial polyester yarns the elongation of the yarn can be a crucial factor in processing and also 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.
Compared to regular polyester yarns which are more apparel focussed 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 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 the spinnerets, and cools upon hitting 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).
