What Is a Tensometer Used for in Material Testing?
When you manufacture technical garments, PPE, sportswear, or other products where seams must perform under pressure, visual inspection alone isn't enough. You need to know how the material behaves when pulled, stretched or subjected to force.
This is where a tensometer machine can play an important role.
At Ardmel Automation, we work with manufacturers who need seam sealing tapes, seam sealing machines and testing equipment to develop products that perform consistently. A tensometer provides measurable data about the strength and behaviour of materials, helping manufacturers make better decisions during product development and quality control.
But what exactly does a tensometer test, and why is it relevant when working with Seam Sealing Tape?
What Is a Tensometer Machine?
A tensometer is a type of material testing machine used to measure the force required to break, tear or deform a material.
During a typical test, a sample is securely held between clamps while a controlled pulling force is applied. The machine measures the force exerted on the sample until it reaches a defined failure point.
This allows manufacturers to understand characteristics such as:
- Breaking force
- Tearing force
- Material strength
- Stretch and deformation
- Failure points
- Comparative performance between materials
A tensometer can therefore provide information that cannot be obtained from simply looking at a finished product.
For textile manufacturers, this is particularly useful when assessing fabrics, seams and bonded constructions. A tensometer is often used alongside other fabric testing equipment to build a clearer picture of how a material will perform in its intended application.
What Is a Tensometer Used for in Material Testing?
The main purpose of a tensometer is to determine how much force a material can withstand before it tears, breaks or otherwise fails.
For example, a manufacturer developing a technical garment may need to compare two different fabrics. Both may look and feel suitable, but tensile testing could reveal that one withstands considerably more force than the other.
The same principle applies to seams and bonded areas.
Testing can help manufacturers investigate:
Tensile Strength
Tensile testing determines how much pulling force a material can withstand before failure.
For fabrics, this can provide useful information about durability and suitability for demanding applications. Tensile testing is commonly used in textile quality control and material characterisation.
Seam Strength
A seam can be one of the most vulnerable areas of a garment or textile product. Testing a finished seam can help determine whether the fabric, stitching or bonded construction is likely to withstand forces it endures during use.
For products manufactured using Seam Sealing Tape, this is relevant because the tape needs to remain securely bonded to the material.
Tearing and Breaking Forces
A tensometer can measure the force required to tear or break a sample. Ardmel's TE-10 Tensometer measures breaking and tearing forces up to 980 N.
This can be useful when comparing different fabrics, construction methods or finished samples during product development.
Why Is Tensometer Testing Important for Seam Sealing Tape?
A good seam sealing process involves more than simply selecting a tape and applying it to a seam.
The tape, fabric and application process all need to work together.
Seam Sealing Tape is commonly used on technical outerwear, waterproof garments, mountaineering tents, sportswear, PPE and other products where controlling water or moisture through seams is important.
When developing a new product, manufacturers may need to establish whether a particular tape provides the required adhesion and durability on a specific material.
Tensometer testing can help provide measurable evidence.
For example, a manufacturer can prepare samples using a selected fabric and seam tape, apply the tape using a seam sealing process and then test the finished construction. If the sample fails at a low force, the manufacturer has to investigate the cause before moving into full-scale production.
The issue could relate to:
- Tape and fabric compatibility
- Insufficient bonding
- Incorrect temperature
- Incorrect pressure
- Machine speed
- Material characteristics
- Tape selection
This makes material testing a valuable part of the development process rather than something that only happens after a problem has occurred.
How Does a Tensometer Test a Material?
The process is relatively straightforward.
First, a representative sample is prepared. Depending on the purpose of the test, this could be a piece of fabric, a seam, a bonded section or another material construction.
The sample is then positioned securely in the machine's clamping system.
Once the test begins, force is applied progressively. The tensometer measures the force required to stretch, tear or break the sample, providing an objective result for comparison.
Testing several samples can provide a more useful understanding of consistency than relying on a single test.
At Ardmel, our TE-10 Tensometer is developed with a portable design, simple clamping system and digital interface. It can measure breaking and tearing forces up to 980 N and is suitable for textile and garment manufacturing, quality control and research and development applications.
Can a Tensometer Help With Seam Sealing Machine Settings?
Yes, testing can also support optimisation of a seam sealing process.
A seam sealing machine uses controlled heat, pressure and speed to activate and apply the tape to the chosen material. The correct settings can vary depending on the fabric and tape being used.
If a finished sample does not provide the required performance, testing can help manufacturers investigate and adjust the process.
For example, a manufacturer may test samples produced using different combinations of:
- Seam sealing tape
- Temperature
- Pressure
- Machine speed
- Fabric type
The resulting test data can then help identify a suitable production setup.
This approach is particularly useful during new product development, where manufacturers may be working with unfamiliar fabrics or developing bespoke products.
What Industries Use Tensometer Testing?
Tensometer and fabric testing equipment can be useful across a wide range of industries where material performance matters.
These include:
- Technical outerwear
- Sportswear
- PPE
- Medical textiles
- Automotive interiors
- Industrial textiles
- Outdoor equipment
- Protective clothing
At Ardmel, our seam sealing technology is used across applications including technical clothing, sportswear, medical products and automotive components. We also provide testing equipment designed for garment and textile applications.
Why Combine Material Testing With Seam Sealing?
Choosing the right Seam Sealing Tape is only one part of creating a reliable finished product.
The fabric, tape, adhesive and application process need to work together. A seam sealing machine must also apply the tape consistently under the appropriate conditions.
This is why we take a complete approach at Ardmel.
Alongside our range of seam sealing machines, we manufacture seam sealing tapes and adhesives and provide testing equipment for textile applications. Our technical team can also work with manufacturers to identify suitable tape and adhesive solutions for specific materials and applications.
For more specialised requirements, our Ardmel CREATE service can help develop bespoke seam sealing tape solutions around a customer's particular material and production requirements.
Choose the Right Testing and Seam Sealing Solution
A tensometer machine gives manufacturers something extremely useful during material development: measurable information.
Rather than relying solely on appearance or assumptions, tensile and tearing tests can help establish how materials and finished constructions respond to force. When combined with the right Seam Sealing Tape and seam sealing machine, this can support a more consistent and reliable manufacturing process.
At Ardmel Automation, we have been developing specialist machinery and seam sealing technology for decades. From seam sealing tapes and machines to textile testing equipment, we can help you find a solution suited to your application.
