Embodiment

[0017] A kind of production method of nylon 6 semi-dull fine denier high orientation filament, comprises the following steps:

[0018] (1) Melting: The nylon 6 semi-dull chip raw material is introduced into the screw extruder through the feed bin and melted, so that the raw material is molten and becomes a spinning melt; the melting temperature in the above screw extruder is 255-275 ° C.

[0019] (2) Spinning: the above-mentioned spinning melt is input into the spinning box, and after metering, it is pressed into the assembly to form a tow; the temperature of the above-mentioned spinning box is 256-274°C, and the spinning speed is 4800-5100m / min .

[0020] (3) Cooling: the above-mentioned tow is cooled through side blowing, oil nozzle and tunnel;

[0021] (4) Forming: the above-mentioned cooled tow is subjected to pre-entanglement, intertwining treatment, traction treatment, and winding forming to form nylon 6 semi-dull fine denier high-oriented filaments. The above-mentione...

Abstract

The invention discloses a nylon 6 half extinction thin denier high orienting filament producing method, which comprises the following steps: (1) fusion, leading raw material of nylon 6 half extinction section into screw extruder through bin to melt, making raw material to present molten state into spinning flux; (2) spinning, putting spinning flux in spinning box; compressing in component part to form fiber group after measuring; (3) cooling, cooling fibre group through cross air blasting, bean and chimney; (4) modeling, making cooled fibre group to cool and form with the treatment of pre-whirling, cold drawing, heat setting, whirling and drawing. The invention simplifies the producing method, which reduces the cost.

Description

technical field [0001] The invention relates to a production method of nylon highly oriented filaments. Background technique [0002] With people's urgent demand for high-grade, thinner, and transparent clothing fabrics, the market demand for semi-dull fine-denier high-oriented filaments is increasing. The types of high-oriented filaments produced by existing processes are single, and the winding time Long, after the slice is melted, it stays in the screw and spinning box for a long time, the viscosity loss is large, there are many broken ends, the spinning tension is small, the spinning is difficult, the woven fabric lacks softness, poor formability, and dyeing performance Difference. Contents of the invention [0003] The object of the present invention is to overcome the shortcoming of prior art, provide a kind of production method of nylon 6 semi-dull fine denier high orientation filament, this production method is simple and convenient, easy to operate, low productio...
