It is often included in yarns to add additional strength, elasticity, and durability but can be spun and put into 100% nylon yarns as well.
Nylon is much stronger than Polyester yarn (strength to linear density ratio - Tenacity) and has better abrasion resistance. However, it elongates by 3.5% and absorbs up to 4% of its weight in water, making it less suitable for use outside.

High Elasticity
Nylon yarn is an extremely durable material that possesses excellent strength and elasticity. These features make it an ideal choice for use in a wide range of applications, from fishing nets to sports apparel. In addition, its ability to regain shape after washing is one of the key factors that drive growth in the global nylon market.
Nylon is a polyamide fiber that has been around for decades. This material is typically used in novelty elastic yarns, and is also added to polyester and other man-made fibers to increase their strength, elasticity, and durability.
The tensile strength of nylon yarns can be significantly increased with the addition of an elastane component. In this case, the elastane will be wrapped around the yarn, which will allow for an increase in tensile strength while maintaining the elasticity and durability of the fabric.
Additionally, a high percentage of elastane will enhance the breaking strength of the yarn and thereby improve its performance. In addition, the elasticity of the yarn will be enhanced, which can increase wearability and provide additional support during activity.
Moreover, the elongation at break of these fabrics will also be improved by increasing the percentage of elastane. In fact, elongation at break values for these fabrics will be much higher than those of the non-elastane knitted fabrics.
These properties are further influenced by the construction of the fabric. Loose fabrics are breathable and less sweat-absorbent, while dense fabrics are more stable and provide greater protection against UV radiation and climatic changes. The warp and weft count of the fabrics also have a significant influence on these properties.
As a result, it is essential to choose the right type of yarn for each application. Nylon has a significantly higher tensile strength than polyester, which means that it can withstand a greater tensile load per unit length of yarn. However, this can reduce the weight of the fabric, so it is important to consider this when choosing a yarn.
In addition to this, the elasticity of the yarn will be affected by the spinning technology used. Twisting, plying and cabling are all different ways of enhancing the elasticity of a polyester or nylon yarn. These techniques are not standardized, so they will vary with the specific polyester or nylon yarn that you’re using.

High Tensile Strength
High tensile strength is one of the most important and widely measured properties of materials that are used in structural applications. It is defined as the maximum stress a material can withstand without breaking when it is pulled or stretched. Some materials break sharply, called a brittle failure; others deform before fracture occurs.
High elastic nylon yarn is a synthetic fiber with high tensile strength. It can also resist abrasion and flexing and is often used in thin, light, and flexible woven or knitted fabrics.
It can be dyed and is easy to form, making it a popular choice for fabric manufacturers. It can be used in a variety of textile applications, including sports apparels, fishing nets, and hats.
Some types of nylon are even able to absorb water. These include Nylon 6 and Nylon 66. These types of nylon yarn have a higher tensile strength and elasticity than other synthetic fibers.
Nylon is a semi-crystalline polyamide that has high tensile strength, elasticity, and good resistance to abrasion. It is an excellent material for hoses and tubes, crankcases, and oil containers.
In addition, it can resist heat, abrasion, and water absorption. These properties make it a popular material for insulating cables, motors, and switches.
Nylon has a low melting point, making it easy to produce. It can also be molded, allowing for a faster processing cycle.
It can be formulated to meet specific performance requirements, such as heat stability, electrical insulation, and chemical resistance. It can also be modified to provide added benefits, such as high UV radiation and ozone resistance.
The tensile strength of nylon is measured in pascals (Pa), a unit of force per square metre. It can also be measured in newtons per square metre (N/m2).
There are different ways to measure tensile strength, depending on the type of material. The most common is to use a tension gauge, which will measure the amount of pressure exerted on the sample by pulling it with a specified force.
Some other methods may be used to measure tensile strength, such as bending and shear testing. In these tests, a piece of the material is bent at a specified angle.
High Abrasion Resistance
High abrasion resistance is one of the most important features for a fabric. It allows you to enjoy outdoor activities without worrying about damage to your clothing and equipment. The abrasion resistance of the fabric depends on several factors, including the fibre type and the cohesion of the yarns.
When it comes to abrasion resistance, nylon is one of the best choices. It offers excellent abrasion resistance because it is durable, flexible, and lightweight. It also withstands water and most chemicals, so it is suitable for many different types of clothing.
Nylon 6.6 is a strong and sturdy fibre that provides abrasion resistance to your clothing. It also has a tough water repellent and water pressure PU coating, which makes it perfect for outdoor wear.
Abrasion resistance can be achieved by using a variety of techniques and materials, but the most common way is by weaving. This technique uses a special type of thread that consists of an elastomeric core fiber and another type of nylon yarn wrapped together.
The abrasion resistance of this yarn is significantly higher than other types of thread. This is because it is woven rather than knitted, which helps to protect the fibres.
Moreover, this yarn is also very durable and flexible. It withstands water and most chemicals, so there is no need for it to be washed frequently. It is also comfortable to wear, and it has a good grip.
This type of yarn is used to make abrasion resistant jackets and other pieces of equipment that are worn by heavy machinery. It is ideal for use on cranes and stacker reclaimers, as it helps to prevent damage to the gears.
In addition, this type of material is useful for cable applications that require high abrasion resistance. It is also used for sandblast curtains and bumpers.
When it comes to sandblasting, the material used is important because it determines how quickly the abrasion wears down the part. A softer elastomer could wear out faster than a harder one, so it is crucial to choose the right one.
Water Absorption
The high elastic nylon yarn elongates rapidly when it is in contact with water. This enables it to absorb up to 4% of its weight in water, which is a significant advantage over polyester color yarn. This also means that it is more suitable for use outdoors, as it will weather the elements.
When used in disposable diapers, the yarn must be able to absorb the urinary fluid or body fluid discharged by users in a timely manner. This is the reason why it is essential that the yarn retains a sufficient degree of rubber-like elasticity and strength after water absorption and shrinkage.
Until now, a water-absorbing shrinkable material which meets all the four requirements has been difficult to be found in the market. This is because, in order to meet the above four requirements, a water-absorbing shrinkable yarn must be high in rate of shrinkage upon absorption of water, high in rate of appearance of shrinkage stress and high in strength after water absorption and shrinkage, and must exhibit rubber-like elasticity after water absorption and shrinkage.
Furthermore, the tensile strength of water-absorbing shrinkable yarns depends on how they are processed after their manufacture and on which fiber is used in them. In particular, it is important that a water-absorbing shrinkable yarn be able to maintain a sufficient degree of strength when the fabric is woven or knitted and when the yarns are subjected to harsh conditions such as those associated with violent movements by users (e.g., when the users are in an agitated state such as when they urinate while lying on their side or when they discharge diarrheal stool violently).
For this purpose, a check experiment was conducted on a mix-twisted yarn made of a fiber capable of shrinking upon absorption of water and a fiber substantially incapable of shrinking upon absorption of water. The result was that, while the fiber of the yarn could shrink to a considerable extent upon absorption of water at 35deg C., the rate of shrinkage stress appearance on water absorption was too rapid to allow the yarn to retain rubber-like elasticity and strength after water absorbtion and shrinkage.
