Understanding Twine Strength

When you choose twine for any task, understanding its strength is very important. The strength of twine tells you how much force it can handle before it breaks. This knowledge helps you pick the right type for safety and effectiveness.

Tensile Strength Explained

Tensile strength is a key measure for twine. You also know it as breaking strength. This value tells you the amount of weight, tension, or force needed to break the twine. Manufacturers measure tensile strength in pounds or kilograms. For twine, it specifically means the Kilogram Force (Kgf) that a single, unknotted length of twine can withstand before it breaks.

Testing methods vary depending on the type of fiber. For multi-filament thread, technicians use rope grips. They measure how much the thread stretches with an optical long-travel system. This follows Standard DIN EN ISO 2062. If you test monofilaments, you follow ISO 11566. Testers use spring-loaded grips with a paper frame because monofilaments are small and sensitive. When testing rovings, they use 270° capstan grips until the material breaks. The results appear in a force-displacement diagram. Double capstan grips create a two-step force gradient. This ensures the specimen breaks at the correct length without slipping. A force-strain diagram shows these results. Aramid yarn tensile tests follow DIN EN 12562. These tests also use capstan grips, and results show in a force-strain diagram. For two-ply thread, pneumatic capstan grips are used according to EN ISO 2062. They measure elongation by how far the crosshead travels.

Factors Affecting Twine Strength

Many things influence the overall twine strength. The material it comes from plays a big role. Twine can be made from natural materials like linen, hemp, cotton, and jute. It can also come from synthetic materials such as polyester and polypropylene. Polypropylene twine, for example, offers great strength and durability. It has minimal stretch and resists rot, mildew, and moisture well.

Manufacturers can add special ingredients to twine. These additives improve its strength and durability. They can make it more resistant to rubbing and wear. UV inhibitors protect the twine from sunlight. This stops it from breaking down too soon. The way manufacturers make and wind the twine onto a spool also matters. The first few meters might look uneven or kinked. This is normal. The twine straightens out when you pull it tight. It also gets tensioned through spring clamps and twine brakes before it reaches the knotter. You just need to make sure these brakes are set correctly.

Tying a knot in twine reduces its overall strength. The type of knot you use changes how much strength you lose. A Cormick knot keeps 75% of the twine’s original strength. A Deering knot, however, only saves 55%. The thickness of the twine also affects how well it forms secure knots. Thicker twine, especially older types, might struggle to make long-tailed, secure knots. This can cause the knot to open after a bale is ejected. Other factors like alloying elements, impurities, and how fine the grain size is (improved by heat treatments) can also change a material’s tensile strength.

Breaking vs. Working Load

You need to understand the difference between breaking strength and working load limit (WLL). These terms are crucial for safe use of any twine.

Breaking strength is the point where a new piece of twine breaks in perfect lab conditions. You should never use twine at or near its maximum breaking strength, except in extreme emergencies. If you subject a product to forces near its breaking strength, you should retire it. Even if you see no damage, it is designed to withstand such force only once. When you choose gear, pick a product with a breaking strength much higher than the force you expect.

The Working Load Limit (WLL) is different. It is the maximum safe load your twine should carry in real-world use. The WLL is a deliberately conservative number for your safety. You can repeatedly use products at their WLL. This is the true value you should consider for regular use. It ensures reliability and longevity. The WLL is a fraction of the breaking strength. A ‘safety factor’ determines this fraction, and it changes based on the material. This safety factor accounts for wear, bending, knots, shock loads, and environmental factors.
