Problems solved by technology

[0005] For full-dull nylon fiber because of its matting agent TiO 2 Due to the abnormal water content of raw materials, unreasonable temperature design of melting heating section, improper control of oil level and oil amount, rough drafting process, etc., nylon fine denier is prone to poor evenness and wool Many, poor dyeing uniformity and other defects cause inconvenience to the subsequent weaving process, and the quality of the fabric is low

Embodiment 1

[0033] A kind of production method of 20D / 24F full-dull nylon 6 full-drawing yarn, comprises the steps:

[0034] 1) Drying of slices: Slice the raw material of full-dull nylon 6 and dry it in vacuum;

[0035] 2) Extrusion melting: the dried slices are melted through a twin-screw extruder, and the melt is extruded, and then evenly distributed to each spinning box through the melt distribution pipe;

[0036] 3) Spinning forming of the spinning box: the melt in the spinning box is metered by a metering pump, and the excess monomer impurities are first extracted by a monomer suction device, and then the melt is evenly distributed to each spinning assembly by an equal-length pipeline In the process, after the melt is sheared by the metal sand in the component sand cup, it is finally sprayed out from the spinneret to form primary filaments;

[0037] 4) Cooling and oiling by side blowing: the primary tow is cooled and shaped by side blowing conditions of constant temperature and hum...

Abstract

The invention belongs to the field of synthetic fiber processing, relates to a preparation method for a nylon 6 fiber and discloses a production method for a 20D / 24F complete-extinction nylon 6 fully-drawn yarn. The production method comprises the following steps of: (1) slicing and drying until the water content is 400-600ppm; (2) extruding and melting by a twin-screw extruder; (3) extracting excessive monomer impurities by a single sucking device and performing spinneret and forming by a spinning manifold; (4) laterally blowing, cooling and oiling at constant temperature and humidity; (5) drafting and setting; and (6) winding to form a silk cake. The production method disclosed by the invention has the advantages of simple and feasible process and low processing cost as well as stable product quality, uniform evenness, low hairness ratio, favorable dyeing effect and excellent mechanical property by optimizing parameters.

Description

technical field [0001] The invention belongs to the field of synthetic fiber processing, and relates to a preparation method of nylon 6 fiber, in particular to a production method of 20D / 24F full-dull nylon 6 full-drawn yarn. Background technique [0002] With the continuous improvement of material living standards in today's society, people's requirements for clothing fabrics are not only for covering the body, being practical and durable, but also requiring novel styles, beautiful appearance, and comprehensive functions such as comfortable wearing, hygienic and convenient for sports. . [0003] At present, fabrics based on synthetic fibers are used more and more widely in the market, and their quantity is also increasing year by year. Among them, nylon dominates the market due to its excellent mechanical properties, wear resistance, elastic recovery and other advantages, and has become the first choice for high-end fabrics such as sports, outdoor and down. With the conti...
