Tensile Strength Tester for Fabrics: Why It Matters in QC
Every day living includes many things for us as individuals, the most important after food is clothing. Proper clothing style and material show an individuals choice and thought process. Every colour speaks for itself, and every fabric justifies the colour, that what is called a good clothing fabric. Such fabrics are expensive but are worth it. But is it that simple to decide on a fabric? Well, its not, every fabric goes through many processes from being a single strand thread to a full, fledged clothing fabric. There are many testing instruments its expected to pass through, ensuring the quality is enhanced and built to withstand the long run.
What are the instruments used for testing a Fabric?
Testing Instrument | Usefulness of the Instrument |
| Tensile Testing Machine | It helps to determine the degree to which a fabric will be ruptured or will tear. |
| Abrasion and Pilling Testing Machine | The fabric is rubbed against each other and then fixed on a grinding platform to determine the degree of damage the clothing will withstand. |
| Moisture Management Testing Machine | Used to determine the absorption, drying, and moisture-holding capacity. |
| Hydrostatic Pressure Machine | This method helps in determining the fabrics capacity to hold water capacity. This method is primarily used in testing outdoor clothing like sportswear and rainwear. |
| Sweat Guarding Testing Machine | This method helps to understand the comfort of the fabric and how the fabric will react with the bodys heat and temperature. |
| Flame Testing Machine | A sample fabric is burnt to check the fabric’s capacity and burning rate with time to determine its reaction to any combustion. |
| Air Permeability Testing Machine | This method of testing fabric helps to understand the breathability of the fabric and also helps in understanding the fabrics resistance under high air pressure. |
| Lab Dyeing Machine | The best method to discover the fabrics capacity to be dyed and washed. Various types of fabrics can be tested in this machine. Most prominently used by the chemical and dye industries. |
How is Tensile Strength measured or calculated?
The Tensile Strength method is also known as the Ultimate Tensile Strength. The name itself justifies that the whole focus is to stress the material to determine the longitude of the product. The Tensile strength testing method is popularly and universally used in many industries, not only the Textile industry but also Plastics and Rubber Industries, Wood, Aerospace and Automation, the Petroleum industry, Medical Equipment, Metal, Paper and Packaging, and Electronics as well.
The Tensile strength is measured using two most common measuring units, which are against the cross-sectional area, are (PSI) and (MPa) (Megapascals and Pound Square Per Inch)
Tensile Strength is formulated and calculated as Tensile Strength (S) = Force Required to Break the material (P) divided by the original cross-sectional area of testing or ground of testing (A), i.e., S=P/A, P/A. This formula helps to discover the ultimate stress exposed on a material that a material can withstand, but also its ultimate breaking point.
Here are 3 simple steps that need to be followed while calculating the Tensile Strength:
1. Prepare a sample that needs to be tested
2. Place the sample on the Tensile Strength Tester
3. Once the sample is placed, its pulled by the grippers, and the digital screen displays the Tensile strength of the material.
Every material has a different tensile strength range; record the same in accordance with the material tested.
Why the Tensile Strength tester is so important for the Fabric Industry? Why does it matter in Quality Control?
Tensile Strength comes into the picture when a fabrics durability is to be determined. This durability explains how the fabric will sustain in the long run. The fibre strands in the fabric are essential and responsible for the fabric’s strength and flexibility. The more reliable the fabric is, the more confidence a buyer shows while purchasing the fabric from the textile manufacturers. Every fabric is expected to continue for a longer period of time than expected.
This stress test on the fabric helps to discover the capacity of the fabric. A fabric needs to be more durable, breathable, and comfortable to be marketed. This tensile strength test is the most prominent method used to maintain quality control, helping manufacturers to produce better fabric, promising long, durable years. This quality control brings in a revolutionary change in the manufacturing of fabric, where good, comfortable, and affordable fabric is manufactured.
The fabric tensile strength tester uses certain common standards, that is, ASTM D5034 and ISO 13934. Every fabric tested under the tensile testing method has two types of testing methods: The Strip fabric method and the Grab fabric method.
The Tensile Strength Testing comes with two types of column testing methods:
1. Single Column Tensile Strength Tester: This method is considered to be cost-effective and applies less force. Mostly used by the Textile laboratories as a lab instrument.
2. Dual / Double Column Testing Strength Tester: This is exactly the opposite of a single column tensile testing machine; its expensive and requires a large space, while the vibrations are less while applying force than the single column tensile testing machine.
Is the only Tensile Tester method used for the Steel Industry?
Before any real-time project, every engineering industry has to use the Tensile Strength Tester on the steel materials they are going to use. While only the tensile tester method is not viable for the steel industry. Tensile Strength is different and varies from material to material. The tensile strength range for fabric is very different from the tensile strength range for steel. There are two different methods used to determine the strength of steel.
1. Tensile Strength Test for Steel: Tensile Strength is the stress applied to determine the maximum stress steel can handle when under stress, either the steel is drawn out or it stretches to its maximum limit until it breaks down. The whole idea of Tensile Testing for a steel sample is to recognise its form being changed from an elastic position to a permanent position or deformed structure. When a steel sample is tested under a Tensile Strength Tester, two outcomes occur when failure in the testing appears, namely;
2. The Ductile Failure Outcome: The very first stage, where the steel takes less time to deform.
3. The Brittle / Rigid Failure Outcome: The last or final stage, where the tensile strength is measured.
4. Yield Strength Test for Steel: This method is slightly reliable for the steel industry and varies a bit from the traditional tensile method. This method also uses maximum stress on the material, and the final result of this method is permanent deformation of the material. In this method, the original shape or elasticity of the product changes to a permanent or deformed shape, and there is no reversal if the same.
It is very important to understand that once a steel sample changes its shape, it is irreversible, and no method can bring it back to its original shape.
