When it comes to sportswear, fabric quality matters for performance, comfort, and durability. To ensure top-notch quality, manufacturers rely on five key tests:
- Abrasion Testing: Measures resistance to wear and tear from friction.
- Strength Testing: Assesses how much stress fabrics can handle before tearing.
- Pilling Testing: Checks if the fabric resists forming annoying fiber balls.
- Color Testing: Ensures colors stay vibrant after washing, sweat, and sunlight exposure.
- Shape Testing: Confirms fabrics maintain their fit and elasticity over time.
These tests guarantee that your sportswear holds up during intense workouts, stays comfortable, and looks good after repeated use. Keep reading to learn how these tests work and why they’re essential for high-performance athletic wear.
Performance Testing for Garments, Apparel & Footwear
1. Abrasion Testing
Abrasion testing assesses how well a fabric holds up against repeated friction, giving insight into its durability. Two primary methods are widely used to simulate wear and tear under controlled conditions: the Martindale test and the Wyzenbeek test.
The Martindale test, commonly used worldwide, involves a circular motion pattern. The fabric is placed on a platform, while worsted wool or wire mesh discs rub against it in a way that mimics real-life movements.
On the other hand, the Wyzenbeek test, a standard in North America, employs a back-and-forth motion. The fabric is tightly secured, and cotton duck or wire mesh is moved across its surface in "double rubs", testing both the warp and weft of the material.
Key performance indicators for these tests include signs of thread breakage, visible wear, color fading, coating damage, and loss of strength. Testing is conducted under strict conditions, factoring in pressure, humidity, temperature, and the type of abrasive material used. For high-performance sportswear, fabrics are often expected to endure 100,000 cycles or more without significant deterioration. Meeting this benchmark signals outstanding resistance to wear.
The results of these tests can vary based on the fabric’s hardness, elasticity, toughness, and texture. These rigorous evaluations ensure that sportswear fabrics can reliably withstand intense and demanding use.
2. Strength Testing
Strength testing is essential for evaluating how well sportswear fabrics can handle stress and tension during intense physical activities. In the industry, two primary testing methods are commonly used: the strip test (ASTM D5035) and the grab test (ASTM D5034).
The strip test uses wide-jaw clamps to grip the entire width of a fabric sample. This method provides a clear picture of the fabric’s overall tensile strength. On the other hand, the grab test employs narrower clamps that grip only the center of the fabric, mimicking the localized stress that occurs during athletic movements. Together, these tests provide a thorough assessment of both overall and localized fabric strength.
During testing, tensile machines apply increasing force to the fabric until it breaks. The tensile strength is calculated as the maximum force applied divided by the cross-sectional area of the fabric. To ensure accuracy, these tests are conducted under standardized environmental conditions, as factors like humidity can significantly affect results.
Key Performance Factors:
- Nylon can stretch up to 40% of its length without breaking.
- Spandex can expand to five times its original size while retaining its shape.
- Fabrics with plain weave patterns tend to be stronger than twill weaves due to the denser arrangement of threads in both warp and weft directions.
Environmental conditions also have a noticeable impact on fabric strength. Exposure to wind, sunlight, and moisture can gradually weaken both tensile and tear strength. Interestingly, wet cotton yarn is stronger than dry cotton yarn. However, synthetic materials, such as polyester and nylon, generally outperform natural fibers in durability, making them ideal for sportswear.
| Test Type | Application Method | Standard Reference |
|---|---|---|
| Strip Test | Full-width grip | ASTM D5035 |
| Grab Test | Center-only grip | ASTM D5034 |
| Tear Strength | Individual yarn resistance | Multiple standards |
To enhance fabric strength, modern manufacturers often blend different fibers. For example, polyester is known for its excellent wear resistance, while nylon offers outstanding durability. These testing methods ensure that sportswear is built to endure the physical demands of athletic performance while maintaining its structure and reliability.
3. Pilling Testing
Pilling plays a key role in evaluating the durability of sportswear fabrics, much like abrasion and tensile strength. This test measures how well fabrics resist the formation of those pesky little fiber balls – commonly known as pills – that can form on the surface during use. These pills not only affect the look of sports uniforms and gear but can also impact their performance.
The testing process mimics real-life friction caused by activities and washing. Manufacturers rely on standardized methods to measure pilling resistance, which helps determine the fabric’s overall durability and quality.
Testing Methods and Equipment
Different methods are used to test pilling resistance, depending on the type of fabric. Here’s a quick breakdown:
| Method | Application | Best For |
|---|---|---|
| Martindale | Circular rubbing motion | Knitted fabrics |
| Random Tumble | Tumbling action | Woven fabrics |
| Circular Locus | Rotary motion | Most knitted materials |
| Pilling Box | Contained tumbling | Dense woven fabrics |
These tests are performed under controlled conditions, using continuous friction cycles. Once the cycles are complete, experts grade the fabric’s pilling level against standardized visual scales.
Factors That Influence Pilling
Several factors affect how prone a fabric is to pilling:
- Fiber properties: Shorter and finer fibers are more likely to pill.
- Yarn twist: Looser yarns tend to pill more than tightly twisted ones.
- Fabric type: Knitted fabrics generally pill more than woven fabrics due to their looser structure.
- Material composition: Synthetic blends, especially those with polyester, are more prone to forming stubborn pills compared to natural fibers.
Insights from Testing
Knitted fabrics, widely used in athletic wear for their comfort and flexibility, are particularly vulnerable to pilling because of their open structure. Additionally, fabrics made from short-staple yarns are more prone to pilling than those made with filament yarns. These insights are crucial for developing strategies to reduce pilling.
How Manufacturers Fight Pilling
To combat pilling, manufacturers can:
- Use longer fibers in fabric production.
- Increase yarn twist for tighter holds.
- Apply anti-pilling finishes.
- Optimize surface treatments for smoother textures.
Modern testing has shown that these techniques, especially tighter yarn construction and smoother surfaces, can significantly improve a fabric’s resistance to pilling. These efforts are vital for ensuring that sportswear maintains its appearance and performance over time.
