Is all “SPUN” made from similar yarn construction?
The answer is No! When Murata Air Jet spun or MJS was introduced to our industry, the term quickly was shortened to “SPUN” mills and manufacturers have since blurred the lines and stretched the meaning of “spun” to cover everything from Open End Spun, Ring Spun, Blends, Filament hybrids and more. Technically yes, most are produced with some form of “spun” yarn, but not what the industry originally migrated to in the 1990’s. The term spun merely means the yarn is formed from smaller yarns (staple) and has a wrapper yarn that holds the small bundles together…the varying technologies to accomplish this are generally referred to as Open End (OE) which is the fastest and cheapest way to spin, Ring (RS) which is softer and has twice the tensile strength as OE but takes up to 5x longer. Each type has its advantages and disadvantages depending on the application.
