Problems solved by technology

[0004] The surface of the synthetic fiber processed by the spout is smooth and the diameter is high, and the multi-bundle fiber is twisted to form a textile primary product for spinning. Because the surface of the synthetic fiber is smooth, the degree of cohesion of the synthetic fiber after twisting is not high. After daily wear and tear, it is easy to break and fluff, and because of the flat and solid internal structure of synthetic fibers, the air retention rate after spinning is not high, which means that the thermal insulation performance of synthetic fibers is not good

Embodiment Construction

[0018] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0019] In this example, see figure 1 with figure 2 , the fuse air tunnel generating nozzle includes a spinneret 100, the spinneret 100 is rotatably connected to an extrusion support 110, the inner wall of the nozzle section of the spinneret 100 is provided with rifling 120 and ribs 130, The rifling 120 and the rib 130 are adjacent to each other.

[0020] refer to figure 1 with image 3 , the depth of the rifling 120 is greater than the width of the rib 130, the depth of the rifling 120 determines the length of the melt passing through the rifling 120, and the length of the melt finally covers the melt formed by the extrusion of the rib 130 Depression, so the length of the melt is greater than the width of the depression to be able to cover the depression.

[0021] The above-mentioned fuse air tunnel generates a nozzle, and the bottom of the nozzle of the spi...

Abstract

The invention provides a fuse wire air tunnel generation sprayer. The fuse wire tunnel generation sprayer comprises a spinning jet, wherein the spinning jet is rotationally connected to an extrusion support; the inner wall of a nozzle section of the spinning jet is provided with riflings and beads which are arranged in adjacency. According to the invention, the riflings and the beads are respectively formed before fuse is sprayed out of the spinning jet, so that covers and sags are formed on the surface of the fuse; after the fuse is sprayed out, because of the rotation of the use, the cover at the outermost layer is tightened by screwing because of relatively long diameter, and the sags are gradually covered, so than an air tunnel is formed in a synthesis fiber by cooling the fuse, and the air content of the synthesis fiber is improved.

Description

[0001] Technical field [0002] The invention relates to the field of synthetic spinning equipment, in particular, to a spinning nozzle for controlling the air content of fused filaments. Background technique [0003] One of the main forming methods of melt spinning chemical fibers, referred to as melt spinning. The main varieties of synthetic fibers such as polyester, nylon and polypropylene are produced by melt spinning. The main features of melt spinning are high winding speed, no need for solvents and precipitants, simple equipment, and short process flow. Fiber-forming polymers that have a melting point below their decomposition temperature and can be melted to form a thermally stable melt can be formed by this method. Melt spinning is referred to as melt spinning, which is to heat and melt the polymer. The fiber-forming polymer is heated and melted in the screw extruder. The strips are oiled and wound, stretched and thinned to form fibers. [0004] The surface of the...
