Short definition
A continuous filament, texturised thread is produced by permanently crimping continuous filaments using a process known as false twisting. Usually made from polyester or polyamide, the resulting construction is bulky, voluminous, soft and highly elastic, with a matt rather than smooth, shiny appearance.
Due to its special properties, typical areas of application include serging and flatlock seams in the lingerie and clothing sector, as well as edge covering on carpets.

FAQ
-
A texturised continuous filament thread is made from endless filaments that are permanently crimped using a process called false twisting. This creates a bulky and elastic yarn structure.
-
False twisting is a process in which continuous filaments are mechanically crimped and heat-set, giving the yarn permanent bulk and elasticity.
-
Due to the crimped structure, the yarn becomes voluminous and soft, creating a bulkier appearance compared to smooth continuous filaments.
-
Texturised filaments are usually made from polyester or polyamide.
-
Texturising increases elasticity, softness and volume. It also creates a matt appearance compared to smooth filament threads.
-
Yes. The crimped structure provides high elasticity and flexibility, making them suitable for stretch applications.
-
It has a soft feel and a matt, textile-like appearance rather than a smooth, glossy surface.
-
Typical applications include serging and flatlock seams in lingerie and apparel, as well as edge covering on carpets.
-
Their softness and elasticity improve seam comfort, especially in garments worn close to the body.
-
It combines the strength of continuous filaments with increased elasticity, softness and seam comfort.
