What type of yarn do you need for your round sling?
There are two main types of yarn to choose from when producing a round sling – high performance round sling yarns and commodity round sling yarns. The type you choose will depend on several factors. These include the intended use of the sling, load capacity requirements, and the desired level of durability and strength.
Below you will find some examples of the types of yarns that are commonly used for different types of round slings:
Polyester is a synthetic fiber that is commonly used in the production of round slings. The benefits are clear. It is strong, lightweight, and has a high resistance to stretching, making it an ideal choice for lighter lifting applications. Polyester round slings are also resistant to UV rays and abrasion, which makes them suitable for outdoor use.
High Modulus Polyethylene (HMPE)
High Modulus Polyethylene or HMPE yarns such as Dyneema, Spectra and, Titan, are long chain Polymers that have very high linear density. HMPE is often used in the production of round slings for high-capacity lifting applications. An HMPE round sling has a very high strength-to-weight ratio, excellent fiber fatigue properties, and low elongation.
Vectran is a high-performance type of yarn used to produce round slings. It is spun from liquid crystal polymer (LCP). The fiber is five times stronger than steel and has high heat resistance, good chemical stability, stiffness, and great linear strength. Its UV stability is limited, but coatings and finishes can mitigate these effects.
Aramid is an abbreviation of aromatic polyamide. Aramids are another type of high-performance yarn that are popular for their broad range of potential applications. They have a high strength-to-weight ratio and dimensional stability. Furthermore, aramids are effective over an extremely wide temperature range, have low flammability and a well-defined lifespan.
Overall, the type of yarn used in the production of a round sling will depend on the specific lifting application and load capacity requirements. It’s vital to consult with a reputable round sling manufacturer or yarn supplier to determine the most appropriate yarn for your specific lifting application.
