False Twist Texturing Machinery
category
False twist texturing machines impart a high twist to thermoplastic filament yarn between a yarn feed and delivery system using a rotating friction disc or pin spindle, simultaneously setting the twisted configuration by heat in a primary heater, untwisting the yarn to zero net twist after the twist zone while retaining the helical crimp geometry set by heat, producing a bulked, crimped yarn whose false twist processing conditions determine bulk, stretch, and elastic recovery.
Role
Produces the dominant textured yarn type globally for polyester and nylon apparel, hosiery, and home textile applications by creating the helical filament crimp that provides bulk, stretch, and cover equivalent to spun yarn at synthetic fibre cost and performance levels, with false twist texturing being the most widely installed texturing technology from its combination of high production speed, process versatility, and ability to produce draw-textured yarn in a single integrated process.
