Embodiment Construction

[0014] figure 1 A schematic structure of a double-slit saturated steam drafting device is shown. In the figure, the double-slit saturated steam drafting device includes a casing that is fixedly connected together by an upper cover 2, a middle shell 4 and a lower cover 8 in sequence, and an upper deflector 3 and a lower deflector 7 are arranged inside the casing. , a central curved wall tube 15 is fixedly connected to the bottom of the upper section deflector 3 central hole, the tube wall of the central curved wall tube 15 is provided with micropores through which a trace amount of saturated steam passes through the silk for instantaneous heating, and the central curved wall tube 15 The lower end extends into the central hole of the lower deflector 7, and the outer side of the curved wall pipe section of the central curved wall pipe 15 is formed by a heat insulating sleeve 13 to form a steam chamber 14, and a top with a tow inlet 16 is provided in the middle of the upper end of...

Abstract

A double-slit saturated steam drafting device belongs to aftertreatment equipment for spinning formation. An upper section of guide plate and a lower section of guide plate are arranged in a shell of the steam drafting device, a central curved wall tube is fixedly connected with the lower part of a central hole in the upper section of guide plate, the lower end of the central curved wall tube extends into the central hole of the lower section of the guide plate, a steam chamber is arranged outside the curved wall tube section of the central curved wall tube, a top cap with a strand inlet is arranged in the middle of the upper end of the shell, and a strand outlet is formed in the middle of the lower end of the shell. The drafting device has two drafting slits, the first slit plays the role of guiding filaments and also has a drafting effect which belongs to cold drafting, saturated steam heats the filaments via permeating through micropores in the central curved wall tube and enters the second slit under the guiding action of the central curved wall tube, the drafting of the process belongs to hot drafting, and under the comprehensive action of two processes of drafting, a good filament drafting effect is obtained, less broken filaments are generated, and geotextile fabric finished products have high strength.

Description

technical field [0001] The invention relates to a double-slit saturated steam drafting device, which belongs to post-processing equipment for spinning and forming. Background technique [0002] After spinning, its structure is not perfect, and its physical and mechanical properties are poor, so it must be post-processed. The main processes of post-processing are drawing and heat setting. The drafting methods generally include steam bath drafting and wet drafting. The fiber is surrounded by saturated steam or superheated steam during steam bath drawing, so that the drawing stress of the fiber is greatly reduced. The traditional steam bath drafting device generally has three chambers, two steam-tight chambers on both sides, and a superheated steam chamber in the middle. The existing three-chamber steam-bath drafting device has a relatively short constant temperature zone, which fails to achieve the ideal purpose of steam drafting. The currently used drafting device consume...
