Description
Technical field
The present invention relates to a kind of friction compound spinning method of type film silkization, belong to textile technology field.
Background technology
Textile fabric can by sources be divided into natural fiber and chemical fibre；Chemical fibre generally comprises regenerated fiber, synthesis
Fiber.Wherein, staple fibre refers to the natural polymer existed originally in nature, because of the length, thick of its macroscopical accumulation shape
The requirement that textile process cannot be met such as thin again through chemical method, it is necessary to be reassociated in fibre morphology, satisfaction weaving
The requirement of processing, such as regenerated celulose fibre, various viscose fibers；Synthetic fibers refer to the small molecule of petrochemical industry as former
Material, through chemical synthesis macromolecule, then is processed into chemical long filament by spinning technique.The production of chemical long filament, according to macromolecule material
Material performance can be divided into melt spinning and solution-polymerized SBR；Wherein melt spinning is directed to itself has obvious heat fusion joint, and melts
Temperature less than decomposition temperature macromolecular material, its technique for prepare spinning melt (including melt section, melt dry etc.) ---
Melt is fed into the high-temperature fusion spinning-drawing machine of twin-screw extrusion, heating is in hot melt flow-like --- heat fluid from spinneret orifice
Extrusion --- stretching and solidification --- dewing oils --- winding of melt stream；The long filament of winding shaping is generally multifilament, containing extremely
Few hundreds of threads, it is impossible to be directly used in textile process, generally require again through sub-wire --- second heat drafting forming --- false twisting or
The post-processings such as air-texturing --- winding；Gather to be similar to the linear shape long filament of cylinder through the long filament of post-processing is general, can be used for
Various composite spinnings；As can be seen that the long filament of melt spinning processing, is applied to textile fabric process complexity, required operation
Long flow path, low production efficiency.Solution-polymerized SBR is directed to itself without obvious heat fusion joint, or melt temperature is higher than decomposition temperature
Macromolecular material, its technique is that high polymer first is dissolved in into the spinning solution that appropriate solvent is made into --- by filtering, deaeration, mixes
Spinning solution is placed in the NaOH solution tank NaOH of solvent spinning machine after conjunction treatment --- through the high pressure effect of propelling, by spinning solution from spinneret orifice
Injected after middle extrusion and be frozen into strand (according to the difference of coagulating bath, being divided into two kinds of wet method and dry method) in coagulating bath, come into being
Silk --- spun filament drawn and solidification --- through washing, except attachment removal coagulation bath and solvent --- dewing oils --- wind；
The long filament of winding shaping is generally multifilament, contains at least hundreds of threads, it is impossible to be directly used in textile process, generally require and pass through again
Sub-wire --- secondary damp and hot drafting forming --- post-processing such as false twisting or air-texturing --- winding；Although the section of long filament can foundation
Shape of spinneret, is made variously-shaped strand, but it is similar cylinder that strand be generally plurality of threads after post-processing to gather
Linear shape long filament, can be used for various composite spinnings；As can be seen that the long filament of solution-polymerized SBR processing, is applied to textile fabric and adds
Work process is complicated, and required process flow is long, low production efficiency.Therefore, existing filament fiber shaping is general all using spinning head
Spinneret orifice linearly sprays shaping, and process flow is long, equipment is complicated.
Friction spun yarn is to be combined to carry out adsorption-condensation fiber with air with machinery, while adsorption-condensation fiber, by
Frictional force carries out rubbing twisting resultant yarn to yarn by revolution dust cage friction roller.Friction spun yarn is that a kind of technological process is short, equipment is simple
Easily, the Yarn spinning method of low speed high yield, low, high financial profit is required to raw fibre length, pattern etc..The Yarn spinning method is 1973
Year, applied for a patent in Austria first by Fu Leer, and with the abbreviation of inventor's name, be named as DREF spinning.1974, not
Le Er companies develop DREF-I type friction spinning machines.Improved raising, puts on display first in the frame exhibition of the 1975 Nian worlds
DREF-2 friction spinning machines, put on market for 1977.1978, Fu Leer companies developed DREF-3 friction spinning machines.Arrive
1986, DREF type friction spinning machines had been sold out 6000 bulls (three or six be a machine), throughout U.S., Britain, Germany, auspicious
More than 60 countries such as scholar, Czechoslovakia, South and North America, Europe, Asia.Friction spinning method is fine with dust cage adsorption-condensation
Dimension yarn, rubbing roller rubbing fiber strip rotate dust cage rubbing fiber strip, the twisting to fiber strip are realized, in final acquisition
Portion's fiber twists with the fingers the yarn of looping conformation in layer, and inside and outside transfer is lacked between yarn interior fiber, and cohesive force is poor between fiber, resultant yarn
It is strongly low.Therefore, when fiber bending rigidity is big, be difficult effectively to turn under rubbing roller or the afterturn effect for rotating dust cage during spinning it is bent,
Winding and twisting resultant yarn, friction spun yarn resultant yarn difficulty are big；Because fiber lacks inside and outside transfer in FRICTION SPINNING yarn yarn formation structure, embrace
Not enough with joint efforts, when high grade cotton yarn is spinned, the fibre weight being fed into friction roll resultant yarn area is few, and yarn strength is too low, it is impossible to carry out
Effectively twist resultant yarn.Therefore FRICTION SPINNING can not produce high grade cotton yarn, general to spin minimum yarn count in 90 special left and right.It is relatively low for modulus
Weak rudimentary or leftover bits and pieces fiber carry out friction spun yarn, fiber has two ways when being transported on cohesion dust cage：Vertical transport
Conveyed with inclining.When wherein using vertical transport mode conveying fiber, because fibrous raw material is very weak, fiber one end first contacts
Static suddenly during to dust cage surface, the other end will bend under inertia force effect, can cause to be transported to dust cage cohesion face
Fiber produce more crotch, loop, middle doubling, random tortuous winding etc. so that it is poor that fiber was arranged before resultant yarn,
Friction yarn strength declines, and yarn quality is poor；To solve the above problems, Britain Masterspinner friction spinning machines are by fiber
Conveying direction entered to favour one angle of yarn axis (15 ° -30 °) by vertical this, improve fiber feed status, it is ensured that
Fiber effectively into yarn length and yarn strength, significantly lifts the spinning yarn quality of fibre frictoin spinning.But it is higher for modulus
The spinning raw fibre of crudefiber crop carry out friction spun yarn, so far also without effective solution.Composite spinning technology is to solve friction
The spinning strength of spinning technique is low, cannot, elasticity big to the rigidity difficult fiber that spins high carry out high-quality resultant yarn, branch high cannot be spinned

Directly in friction roller direction, chopped fiber yarn enters combing roller through feed roller, by the fiber stream of carding assembly single-fiber shape, fiber
Stream enters in the middle of two parallel friction rollers, friction roller parallel with being fed into two under wind-force effect through fiber channel is vertical
Long filament in the middle of cylinder converges twisting resultant yarn, and wherein long filament is located at middle part, and inside and outside transfer does not occur, and chopped fiber is twisted with the fingers with layer and is wrapped over length
The periphery of silk, ultimately forms the FRICTION SPINNING complex yarn of filament core.Wrapped due to being twisted with the fingers for layer between described long filament and chopped fiber
Entanglement structure, long filament particularly used is that, through the good package form of industrialization drawing-off, sizing, winding shaping, long filament is to gather
The linear shape for being similar to cylinder is integrated, monofilament more cannot be effectively distributed in friction resultant yarn area chopped fiber stream in long filament, each
Monofilament cannot effectively be scattered compound with chopped fiber online, and long filament can be only positioned at complex yarn core, without there is inside and outside turning
Move, long filament and short fiber layers are twisted with the fingers clad and lacked and sufficiently mixs, no improvement FRICTION SPINNING yarn interior monofilament and chopped fiber it
Between cohesive force, therefore yarn strength cannot be greatly improved, cannot also solve the problem that FRICTION SPINNING produces high grade cotton yarn, Er Qiechang
The short fiber layers sth. made by twisting looping part of silk cored FRICTION SPINNING yarn is easy to wear to come off, and yarn texture stability is poor, wear-resisting grade is low.
