The speed ratio (D/Y) is the key to determine the bulkiness, elasticity and feel of the processed yarn. The greater the false twist, the greater the crimping force, the more thin and more crimping, the fuller the appearance of the yarn after untwisting, a......

Stretch Ratio of Texturing MachineThe draw ratio is generally determined by the remaining draw ratio of POY, which directly affects the fineness, strength and elongation of the filament. As the draw ratio increases, the strength of the filament increases,......

Texturing machine winding parameter settingAs a craftsman, we all know that the winding processor system of the texturing machine is composed of an electronic control device and a winding processing control program. The stroke correction motor is controll......

Under normal production conditions, as the wire speed increases, the contact pressure between the wire and the friction disc increases, the slippage is small, and the false twist effect is good. However, as the wire speed increases, the deformation and co......

Polyester low elastic yarn (abbreviated as DTY) is a type of textured polyester filament yarn. It uses polyester chips as raw material to spin polyester pre-oriented yarn (POY) at high speed, and then stretches through false twisting and stretching. made.......

With the increase of wire speed, the deformation and cooling time are reduced, the thermoplasticity of the yarn is reduced, and the false twist tension is increased.When stretching and deforming POY, the remaining stretching ratio of the filament should b......

Texturing Machine, Hot Box TemperatureThe temperature of the hot box mainly affects the crimp elongation, color fastness and dyeability of the filament. Different temperatures have a great influence on the various indicators of the fiber. At lower tempera......

False twist tension control in DTY processWith the increase of wire speed, the deformation and cooling time are reduced, the thermoplasticity of the yarn is reduced, and the false twist tension is increased.When stretching and deforming POY, the remaining......

How to Grasp the Control of Residual Torque in DTY ProductionWith the increase of the number of working disks of the false twister, the increase of D/Y ratio and the temperature of the first hot box, the degree of false twist increases, the deformation ef......

Rotor spinning processThe fiber raw materials are prepared before processing (such as ginning of raw cotton, scouring and carbonization of wool, degumming of silk and hemp), and then are opened, mixed, removed, and carded to form fiber strips, which are m......

Rotor Spinning Machine Operating ProceduresImpurities left in the coagulation groove of the rotor will destroy the cohesion of the strands and the transfer of twist, causing the spun yarn to have periodic unevenness, the wavelength is about the circumfere......

Rotor Spinning Machine PrincipleThe fed fiber slivers are opened into single fibers by the rotary carding roller covered with card clothing, transported to the inner wall of the high-speed rotating cup with the airflow, and form yarn tails in the condensa......
