Melt Spinning process of Polyester fiber

Melt spinning process

Melt spinning process of yarn manufacturing is a short term. Its a part of man made yarn preparation from fiber. From polyester chips to yarn preparation is one of the melt spinning process . Melt spinning could be a technique used for fast cooling of liquids. A wheel is cooled internally, typically by water or atomic number 7, and revolved. a skinny stream of liquid is then dripped onto the wheel and cooled, inflicting fast action. this system is employed to develop materials that need very high cooling rates so as to create, like metallic  glasses. The cooling rates doable by melt-spinning square measure on the order of 10⁴ to 10⁷ kelvins per second (K/s).

Polyester chips obtained from reacted chemical combinations are melted and then pumped through spinneret into an air chamber. The extruded stream cools and solidifies into continuous filaments which are then drawn out from chamber twisted or processed or subsequently wounded onto spoons.
