Fabric Tensile Strength Tester(Dual Column Type)

Here are some common applications of a fabric tensile strength tester:

• Quality control testing of woven, knitted, or nonwoven fabrics: Test fabric strength at various stages of production to ensure it meets specification requirements.
• Material development: Textile manufacturers use it to test new materials and blends during product development.
• Fiber and yarn testing: It can test individual fibers, filaments, or entire yarns to determine tensile properties.
• Raw material inspection: Incoming raw materials like fibers, yarns, and fabrics are tested on receipt to verify strength matches the paperwork.
• Manufacturing process control: Fabric strength is monitored through processes like weaving, knitting, and dyeing/finishing to detect issues.
• Wear testing: Simulate effects of wear and laundering by repeated tensile tests to rate fabric durability.
• Finished product inspection: Final textile products are tested before release to avoid weakness failures in use.
• Military/industrial fabric certification: Strong fabrics for protective clothing, equipment, tarps, etc. require certification.
• Forensics: Determine if fabric failure was a product fault or caused by external factors in liability investigations.
• Research and development: Universities and textile labs use it for fabric improvement studies.

Here are some common applications of a fabric tensile strength tester:

• We test the strength of fabric at various production stages. The tests apply to woven, knitted, or nonwoven fabrics. They ensure the fabric meets specifications.

• Textile manufacturers use it to test new materials and blends. They do this during product development.

• It can test individual fibers or filaments. It can also test entire yarns. This testing finds their tensile properties.

• We inspect raw materials when they arrive. They include fibers, yarns, and fabrics. We test them to verify their strength matches the paperwork.

• Manufacturing process control monitors fabric strength. People do it through processes like weaving, knitting, and dyeing/finishing. They use them to detect issues.

• Do wear testing to simulate wear and washing. Do this by doing repeated tensile tests to rate fabric durability.

• We inspect the finished products. We test them before release to avoid weak spots.

• Certifying strong fabrics is key. They are for protective gear, tarps, etc.

• Forensics determine if fabric failed due to a fault or external factors. They do this in liability investigations.

• Research and development: Universities and textile labs use it for fabric improvement studies.

The largest load a tensile strength tester can hold varies. It depends on the specific model. Here are some typical greatest load capacities seen in commercial tensile strength testers:

• Light duty lab testers: 1 kN to 5 kN

• General purpose testers: 5 kN to 20 kN

• Heavy duty testers: 20 kN to 50 kN

• Very heavy-duty testers: Above 50 kN

The largest load capacity needs to match the intended testing applications. For example:

• You can perform fabric and yarn testing using load cells that are under 20 kN.

• Fiber testing may only need 1-5 kN loads.

• Rubber, threads, and films can be 5-20 kN.

• Steel wire rope and chains need 20-50 kN or higher loads.

Top models may offer load ranges. They use interchangeable load cells. This provides flexibility for different materials.

Load accuracy is also important, within +/-0.5% to 1% of the rating. Proper load cell selection ensures test results fall within the rated measurement range.

The largest load capacity depends on material strength and tester specifications. It ranges from 1 kN for delicate tests to over 50 kN for heavy materials.

The tester’s accuracy depends on the model. But, in general, tensile testers aim for high accuracy. Some key points about tensile tester accuracy:

• Load measurement accuracy is within ±0.5% to 1% of the rated load capacity of the load cell. For example, a 20 kN load cell would have an accuracy of ±0.1-0.2 kN.

• Displacement/extension accuracy is also very good, often ±0.5% or better of the full-scale range.

• High-end systems can achieve even higher accuracy of ±0.25% for load and ±0.1% for displacement.

• Factors like system calibration, the load cell type, and the data rate affect accuracy.

• Accuracy is usually specified and guaranteed by manufacturers in technical specifications.

• Industry standards like ASTM D638 prescribe the lowest accuracy level for reported values.

• Calibration is important to maintain the rated level of accuracy over time.

In summary, a top tensile tester can provide load accuracy within ±0.5-1%. It can also provide displacement accuracy within ±0.5%. These accuracies depend on specific product capabilities. This level ensures reliable, reproducible test data. Proper use and calibration sustain the rated level of precision.

A tensile strength tester can achieve the following range of testing speeds:

• Low-speed range: 0.1 mm/min to 50 mm/min

This low-speed range is suitable for testing very thin and delicate fabrics or films. It allows the gradual application of force to prevent tearing.

• Medium speed range: 50 mm/min to 500 mm/min

Researchers conduct most general-purpose fabric and material testing within this medium range. It’s fast enough but also prevents sudden failure of samples.

• High-speed range: 500 mm/min to 2000 mm/min

used for testing plastics, composites, rubber, and other tough materials. Also useful for production line quality checks.

• Very high speed: Above 2000 mm/min

Some advanced testers can achieve very high speeds. They use them for impact testing. They test ballistic materials and aviation composites.

The exact speed capabilities depend on the individual tensile tester model. Higher-rated loads generally mean more mechanical robustness for high speeds.

Yes, tensile strength testers are versatile machines. They can test many types of materials. Some common materials that researchers can test include:

• Fabrics – Different types of woven, knitted, or nonwoven fabrics.

• Yarns – Natural and man-made fibers, filaments, spun yarns, plied yarns.

• Films and thin sheets – Plastic films, foil laminates, paper sheets.

• Rubber and elastomers – Different grades of rubber, seals, o-rings, silicones.

• Composites – Fiberglass, carbon fiber, Kevlar composites, laminates.

• Plastics – Different polymer samples, injection molded parts.

• Metals – Wires, cables, thin metal sheets, aluminum, mild steel.

• Non-metals – Ceramics, concrete, wood, cork, leather, sealants.

• Biological tissues – Tendons, cartilage, and skin tissues from animals/humans.

• Paper and board – Cardboards, corrugated boxes, tissues.

Tensile strength testers are common. Researchers use them to conduct tensile tests. These tests follow various ASTM standards. Here are some of the key ASTM standards related to tensile testing:

• ASTM D638 – Standard test method for tensile properties of plastics. Researchers use most for testing plastics and polymers.

• ASTM D882 – Standard test method for tensile properties of thin plastic sheeting. For films, foils, and other thin flexible plastic materials.

• ASTM D5035 is the standard test for the breaking force and stretch of fabrics. Common for woven, knitted, or nonwoven fabrics.

• ASTM D792 is the standard for testing the density and specific gravity of plastics. The test uses displacement. Calculates properties of polymer materials.

• ASTM D822 – Standard practice for preparing cork composites for test purposes. For testing cork and cork composites.

• ASTM D885 – Standard test method for tensile properties of fiber-reinforced plastics. Used for fiber-reinforced plastics like composites.

• ASTM D2834 is the standard test method for the transition temperatures of fabrics.

• ASTM D2240 – Standard test method for rubber property-durometer hardness. For characterizing the hardness of rubber materials.

Following standardized protocols ensures consistent testing methods and compatibility/comparison of data globally. Instrument calibration is also against reference standards.
