Tear Strength Measurements in Ripstop Nylon When it comes to tear strength, the difference between the measured value and the test result can vary.
The coating of ripstop nylon fabric is widely used in outdoor gear due to the durability of its waterproofness and water resistance. Another key consideration when selecting ripstop nylon fabric is tear resistance. Tear strength indicates the degree to which the fabric can withstand tearing when force is applied. Ripstop nylon fabric's tear strength is quoted in pounds of force or newtons. The higher the tear strength would be the more durable and long lasting the fabric.
Methods for testing the tear resistance of ripstop nylon are:
Ripstop nylon testing There are a few testing techniques that are commonly used to determine the tear resistance of ripstop waterproof nylon fabric. One typical method is the Elmendorf tear test, which measures the force needed to tear through a sample of fabric that has been severed in half. Another approach is the so-called trapezoid tear test—where a fabric sample with a pre-cut trapezoid shape is tested for the tensile force required to cause it to tear.
What contributes to tear strength in waterproof ripstop nylon:
There are a number of issues that could affect the tear strength of the ripstop waterproof nylon fabric. One consideration is the heaviness of the material. Heavier fabrics, however, generally exhibit higher tear strength than lighter weight fabrics. Another consideration is the tightness of the weave. Cloth with a tighter weave is stronger than cloth with a looser weave. Tear strength can also be influenced by the particular finish on the cloth. Heavy weight fabrics with a solid water resistance are usually stronger, by strike through”.
Importance of tear strength in waterproof material of outdoor gears:
Tear resistance is the another point to consider when selecting the waterproof fabric for outdoor gear. When you own outdoor gear you put it through quite a bit - rough trails, life at the crag or on the wall, the hours in-between when your equipment is crammed in the car. Not all fabrics can endure these conditions, some with a greater level of tear strength can survive for a long period that are good for outdoor activities. Plus, the higher the tear strength, the less likely a tear or rip is to develop in the fabric, which can undermine the gear’s performance and longevity.
How to improve tear resistance of ripstop nylon:
Ripstop waterproof nylon fabric’s tear resistance can be improved in a number of ways. One trick is to opt for a fabric with a higher denier. Denier indicates the thread thickness and, as a general rule, the higher the points, the higher the tear strength. Another suggestion is picking a fabric with a close-knit weave. The closer together the yarn, the less space left over that the yarn is not taking up, the tighter the weave, the lesser the chance of the fabric tearing. also, make the fabric more tear resistant by putting a strong waterproof coating on it. Following these hacks you can make your outdoor gears with ripstop nylon never to get damaged soon.
