Is made by spinning a wrap of staple cotton or polyester around a continuous filament of polyester fibers. Afterwards, two or more of these single yarns are twisted together to form the thread. Core threads have fuzz on their surface giving them good lubricity characteristics and also a continuous filament core that contributes to high strength and durability. When wrapped with a cotton wrap, core threads have very good needle heat resistance. When wrapped with a polyester wrap, core threads have excellent chemical resistance and colorfastness. Core threads are used in everything from fine blouses to heavy coveralls and overalls.
Is produced from continuous filaments of nylon that have been bonded together. They have very little twist so that they look like a single cord of yarn. Because of the way these threads are made, they appear to be flat and ribbon-like, which provides a high degree of resistance to abrasion. Monocord threads are exceptionally strong for their size so they are used in the manufacturing of furniture, shoes, and other heavy duty applications.
Is made from cotton or polyester staple fibers that are spun into single yarns and then two or more of these yarns are plied to make a sewing thread. Spun threads have fuzz on their surfacing giving them a soft hand and good lubricity characteristics. Spun threads are used in everything from women’s lingerie to heavy leather gloves.
Twisted Multifilament Thread
Is made from continuous filaments of polyester or nylon that are twisted together into a cohesive bundle and then plied to make the thread. They are then dyed, stretched, and heat set to achieve the desired physical characteristics. Twisted Multifilament threads are available either soft or with an additional bond for better ply security and abrasion resistance. They are exceptionally strong for their size and they have excellent resistance and durability. These threads are used for seaming everything from bathing suits to automobile upholstery.
