DACSOFT - TWISTED MULTIFILAMENT POLYESTER - SOFT
DACFUSE - TWISTED MULTIFILAMENT POLYESTER - BONDED

Multifilament Threads Construction: Refers to a thread construction made from continuous filaments of polyester, which 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 exceptional strong for their size and they have excellent resistance and durability. These threads are used for seaming everything from bathing suits and intimate apparel to automobile upholstery.
