Production method of chinlon 66 high-strength fiber and chinlon 66 high-strength fiber

Abstract

The invention belongs to the technical field of spinning chemical fiber production and particularly relates to a production method of a chinlon 66 high-strength fiber and the chinlon 66 high-strengthfiber. The production method comprises the following steps: drying and tackifying common chinlon 66 pieces by using a drying and tackifying device; melting and compressing the common chinlon 66 piecesafter drying and tackifying in a screw extruder, and melting the common chinlon 66 pieces into spinning melt; quantitatively compressing the spinning melt into a spinning component, and ejecting fiber beams from the spinning component; cooling the fiber beams by using a slow cooling device, drawing single parts by using a single part drawing device, and forming a primary fiber; cooling the primary fiber by using a side air blowing device and a channel in sequence; carrying out oiling treatment on the cooled fiber beams by using an oiling device, and carrying out tension and shaping by using atraction component; coiling the fiber beams after traction and shaping by using a coiling machine, so as to obtain fiber cakes. The production method is capable of making up technical schemes that inthe prior art a chinlon 66 high-strength fiber less than the specification of 150de is produced through one-step method spinning and traction shaping, and has very good popularization prospects.

Description

technical field [0001] The invention belongs to the technical field of textile chemical fiber production, and in particular relates to a production method of nylon 66 high-strength fiber and nylon 66 high-strength fiber. Background technique [0002] Nylon 66 high-strength fiber is a commonly used synthetic fiber. It has a wicking effect, and the softer it feels, it has good comfort and hygiene. The fabric woven with this fiber is very suitable for making mountaineering and hiking. Sportswear for outdoor activities, has the characteristics of wear resistance and high color fastness. [0003] In the prior art, nylon 66 high-strength fibers with specifications below 150 de are usually produced by a two-step process, that is, spinning first, winding into rolls after spinning, and then stretching, deformation and winding. [0004] The nylon 66 high-strength fiber produced by the two-step method has the following disadvantages: [0005] It occupies a large area, requires a lot ...
