Description
Technical field
Category chemical machinery field, is to be related to the process units of chemical fibre.It is exactly to be related to using dry spinning system
The device of standby meta-aramid fibers.
Background technology
The spinning of chemical fibre can be divided into melt spinning and solution-polymerized SBR, and solution-polymerized SBR can be divided into wet spinning, dry method again
Spinning and wet-dry change（Dry-jet wet-spinning）.Dry spinning and wet spinning are all to form fibre using the concentrated solution of fiber-forming polymer
Dimension.From unlike wet spinning, the spinning solution thread extruded from spinneret capillary during dry-spinning is not to enter coagulating bath, but is entered
In entering spinning shaft.By the effect of stream of hot air in path, the solvent in stoste thread is set quickly to volatilize, what is evaporated is molten
Agent steam is taken away by stream of hot air.Stoste solidifies while solvent is gradually sloughed, and is stretched in the presence of winding tension
Length attenuates and forms as-spun fibre.In the spinning stroke of dry-spinning, the removing of solvent is realized by following three step in stoste thread：
1. stoste one goes out spinneret orifice and quickly volatilizees immediately -- flash distillation；2. solvent from inside stoste thread to external diffusion；3. from thread table
Make convective mass transfer towards surrounding gas medium.Spun in journey near one section of spinning head, the mechanism of mass transfer include flash distillation, convection current and
The comprehensive function of diffusion, then pure diffusion just gradually becomes the factor of control mass transport process speed.During dry-spinning, spinning solution with week
Only heat transfer and mass transport process are enclosed between gas medium, any chemical change does not occur.Dry spinning has some with melt spinning
Similarity, the two is all to make high polymer fluid in spinning shaft（Solution or melt）Viscosity reach a certain critical value and reality
Now solidify.Unlike, process of setting is realized by means of thread temperature drop in spinning stroke during melt-spun, and dry-spinning then passes through
Solvent volatilization in stoste thread, superpolymer concentration constantly increases and solidifies.
Meta-aramid scientific name is poly, and the country is also referred to as aramid fiber 1313, and meta-aramid is current height
One of kind with fastest developing speed in performance fibers, is a kind of tec fiber of high comprehensive performance, in protective clothes, honeycomb knot

The important foundation material in the fields such as petrochemical industry, ocean development and high-performance apparel, meta-aramid fibre fibrid and chopped strand are
The basic raw material of manufacture aramid insulating paper and honeycomb paper.
Meta-aramid does not have fusing point, and when temperature exceedes to a certain degree, direct carbonization causes the meta-aramid cannot be by molten
Melt spinning to prepare；The production of meta-aramid fibers can use dry spinning, wet spinning and dry-wet spinning.Dry spinning
Speed is fast, efficiency high, and the fiber skin-core structure weak without skin-core structure or very, gained fibre machinery performance is good, be especially suitable for for
