Is filament yarn stronger than spun yarn?

Effects of manufacturing processes

Spun yarns are less lustrous and generally softer in terms of handle than filament yarns. … Yarns made with longer fibres tend to be smoother, more lustrous and stronger than those made with shorter fibres as do yarns made with fibres that are more aligned.

What is spun yarn?

Spun yarn is made by twisting staple fibers together to make a cohesive thread. Spun yarns may contain a single type of fibre, or be a blend of various types.

What is monofilament yarn used for?

Monofilament yarns are mostly used for making fabrics for special purposes, such as polymer monofilament fabrics for filtration and metal wire fabrics for architectural decoration. The major forms of yarn are those that involve a large number of fibres in their cross-sections.
