The Difference And Connection Between The Number Of Strands Of Elastic Yarn

High elastic yarn is a type of yarn that has a high degree of stretch and recovery. It is often used for knitting garments that need to fit closely and comfortably, such as sportswear, underwear, and swimwear. High elastic yarn can be made from different fibers, such as spandex, elastane, or rubber. The number of plies in a high elastic yarn affects its strength, thickness, and appearance.

Ply refers to the number of strands that are twisted together to make a yarn. For example, a 2-ply yarn has two strands, a 4-ply yarn has four strands, and so on. The number of plies in a high elastic yarn can influence its durability and smoothness. Durability is the ability of a fabric to resist wear and tear, while smoothness is the ability of a fabric to have a fine and even surface.

Generally speaking, more plies and more twist make a yarn stronger and smoother, while fewer plies and less twist make a yarn weaker and coarser. This is because more plies and more twist add more tension and stability to the yarn, making it more resistant to breaking and pilling. Fewer plies and less twist reduce the tension and stability of the yarn, making it more prone to snapping and fuzzing.

However, this is not always the case, as other factors such as the type of fiber, the spinning method, and the knitting gauge can also affect the strength and smoothness of a yarn. For example, a 2-ply yarn made from spandex can be stronger and smoother than a 4-ply yarn made from rubber. A combed spun yarn can be finer and more even than a carded spun yarn. A tight gauge can create more tension than a loose gauge.

Therefore, when choosing a high elastic yarn for your project, you should consider not only the number of plies, but also the other characteristics of the yarn. You can also swatch different yarns and compare their strength and smoothness before you start knitting. You can find some helpful tips on how to choose a high elastic yarn in this article.
