What do you need to know about continuous filament threads?
In continuous filament threads, the single yarns are made from continuous fibres (filaments). In some cases, up to 200 individual filaments are combined to form a yarn (multifilament). The raw materials are mainly polyester and polyamide, but aramids, polyethylene, polytrimethylene terephthalate, polypropylene and polyether ether ketone are also used for technical applications. While the coarser thicknesses are usually 3-ply constructions, the finer qualities are predominantly 2-ply constructions.
Due to their construction, continuous filaments have a smooth, shiny surface and a uniform twisted character. They are also characterised by very high tear resistance and abrasion resistance. Continuous filament yarns are mainly used for shoes and accessories, home interiors and technical textiles.
Well-known AMANN products include Serafil (polyester continuous filament) and Onyx (polyamide continuous filament), as well as Nc-tech, Kc-tech, C-tech, I-tech and Zyex in the Techtex range.
In the clothing sector, only the finest thicknesses are generally used. The main areas of application are overlock seams for cut edges and blindstitch seams.
In the field of embroidery threads in particular, the classic construction type is continuous filament made from trilobal polyester. The trilobal filament shape increases the light-reflecting surface area of the material and ensures the impressive, important shine of embroidery.
FAQ
-
A continuous filament thread consists of endless fibres (filaments). These filaments are combined to form a single yarn, often as a multifilament construction.
-
A multifilament yarn is made up of many individual continuous filaments — in some cases up to 200 — bundled together to form a single yarn.
-
Common raw materials include polyester and polyamide. For technical applications, aramids, polyethylene, polytrimethylene terephthalate, polypropylene and PEEK may also be used.
-
Because they consist of uninterrupted filaments, they offer very high tear resistance and abrasion resistance compared to staple fibre constructions.
-
Continuous filament threads have a smooth, shiny surface and a uniform twisted character.
-
Coarser thicknesses are typically 3-ply constructions, while finer qualities are usually 2-ply constructions.
-
They are widely used in footwear, leather goods, accessories, home interiors and technical textiles.
-
Yes, but generally only in finer thicknesses. Typical applications include overlock seams for cut edges and blindstitch seams.
-
In embroidery, trilobal polyester continuous filaments are commonly used. The trilobal cross-section increases light reflection and creates a high-gloss effect.
-
Key advantages include high strength, excellent abrasion resistance, smooth surface, uniform appearance and reliable sewing performance.
