Difference between High Tenacity and Regular Nylon Yarns
Nylon / Polyamide Yarn
Nylon is widely used all over the world. It was developed by DuPont’s laboratories in the 1930’s. It 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.
There are various types of nylons. The main ones used in textiles tend to be PA6 PA66 types. These can be used and interchanged freely in some application areas but generally there are advantages to each type if we look at specific application areas.
High tenacity yarns are a specific refinement which moves nylon yarn into technical industrial application areas.
Producing High Tenacity Yarns
To produce high tenacity nylon yarn starts with melting the polyester polymer at around 220 degrees centigrade in the case of PA6 and around 265 degrees centigrade in the case of PA66 then spinning to produce continuous filaments. In the case of a Decitex 940/140 high tenacity nylon yarn this means 140 filaments are produced at the same time. The Decitex 940 refers to the weight of the yarn (decitex = weight in grammes of 10,000 metres) so every 0.94 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 typical PA6 and PA66 Dtex 940 high tenacity polyester yarn is generally around 70- to 80 newtons.
As in all textile processes we often need other things and there are trade offs. For many textile processes using industrial nylon 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 3% suitable where stability to higher levels. For some applications such as airbags, nets, ropes, this is a key consideration in the choice of yarn
The elongation of the yarn can also be an important point. The elongation is a consideration in processing but also important in some end uses. Normally specification sheets for high tenacity nylon yarn will reference the elongation at break figure (normally standard yarns are between 20 to 25%) but for many processes the elongation at a specific load amount can be more relevant.
Nylon Yarn Differences and Examples
Compared to regular nylon yarns which are more apparel focussed high tenacity nylon yarns are generally suited toward various uses. PA6 and PA66 yarns are both good on abrasion and wear resistance. They insulate well electrically. Both can be prone to water ingress but PA6 performs better generally on this point. PA6 is better at ageing under heat conditions and less expensive than PA66 normally. PA66 is better at higher temperatures and in general the lower shrinkage nylon yarns are more easily produced in PA66. PA6 is generally slightly stiffer having a slightly higher modulus but some PA66 yarns can be made with the same characteristics. Generally PA66 has a slightly better resistance to most chemicals.
Nets and nettings for sport, cargo and fish and fish farming generally use the Higher Dtex yarns like Dtex 940 and Dtex 1880. PA6 is often chosen here because it has advantages with knot strength and abrasion properties and cost price. Ropes using PA6 yarn are also used in the paper carrier rope and marine industry often plied up into heavier counts. Tyre cord fabrics are manufactured using PA6 (and PA66). Our Dtex 940 nylon high tenacity yarn can be used as it is or plied up to heavier counts for use in these areas or we can also provide Dtex 940 solution, dope dyed nylon yarn where a coloured yarn is preferred.
PA66 is used in parachutes, airbags and sewing threads where it’s better tenacity and lower shrinkage can be advantageous. Narrow fabrics and conveyor belt fabrics are also manufactured using PA66.
