Description
Technical field
The invention belongs to production of chemical fibre field, it is related to the cooling means of chemical fibre, and in particular to ring blows cooling side
Method.
Background technology
In the present invention, term " chemical fibre " is the abbreviation of chemical fibre.Chemical fibre is to use natural polymer or people
The high-molecular compound of work synthesis is raw material, has weaving made from the processes such as spinning solution, spinning and post processing by preparing
The fiber of performance.Chemical fibre is divided into two major class of staple fibre and synthetic fibers again：1. staple fibre, with natural polymer chemical combination
Thing (such as cellulose) chemical fibre made of raw material, such as viscose rayon, acetate fiber.2. synthetic fibers, with artificial synthesized
High-molecular compound is chemical fibre made of raw material, such as polyester fiber, poly- phthalein amine fiber, poly internal olefins nitrile fiber.Chemical fibre
Have the advantages that intensity is high, wear-resisting, density is small, elasticity is good, it is not mouldy, be not afraid of and damage by worms, is quick-drying washable, but the drawback is that dyeability
It is poor, electrostatic is big, fast light and weatherability is poor, water imbibition is poor.
Staple fibre mainly has viscose rayon, nitric acid ester fiber, acetate fiber, cuprammonium rayon and Azlon etc.,
Its towel viscose rayon point common viscose fiber and has New Viscose Fibre (such as high-wet-modulus fibres, superpower viscous of outstanding properties again
Glue fiber and permanent curl viscose rayon etc.).
Synthetic fibers mainly have daiamid-6 fiber, and poly internal olefins nitrile fiber is poly- to match somebody with somebody fiber, poly internal olefins fiber, polyvinyl alcohol contracting
Formaldehyde fibers and special fibre.The 1950s carries out the study on the modification of synthetic fibers, mainly with physically or chemically side
Method improves the properties such as the moisture absorptions of synthetic fibers, dyeing, antistatic, fire-resistant, anti-pollution, anti pilling, while also add chemical fibre
Kind.
The preparation of chemical fibre, is typically that spinning melt first is made in natural or synthesis polymer substance or inorganic matter
Or solution, liquid thread is then extruded as by spinning head (plate) by filtering, metering, then solidification forms fiber.At this time
Fiber is known as as-spun fibre, its mechanical property is very poor, it is necessary to by a series of post-processing processes could accord with textile process and
Requirement.Post-processing is stretched mainly for fiber and heat setting, to improve the mechanical property of fiber and dimensional stability：
Stretching is macromolecular or construction unit in as-spun fibre is orientated along fiber axis, and heat setting mainly makes internal stress pine in fiber
Relax.During spinning filament yarn, cylinder can be wound into through above-mentioned operation；The processes such as curling, cut-out and packing must also be increased during staple fiber processed.
During dry spinning, spinning solution is transported to spinning head by metering pump, and the spinning solution extruded from spinneret capillary is thin
Stream is contacted into spinning shaft with thermal medium (air or nitrogen), by the effect of thermal medium in path, is made in solution thread
Solvent quickly volatilizees, and is taken away by thermal medium stream.
In process of the present invention is realized, inventor find dry spinning head bore number it is few more than wet spinning, itself main reason is that
Spinning solution thread slow curing, the easy adhesion of strand, seriously affects spinning quality before curing.
