Description
Technical field
The present invention relates to a kind of methods of high rigidity fragile fibre short route double twisting resultant yarn, belong to textile technology field.
Background technology
Textile fabric for clothes can be divided into three categories：Woven (tatting), knitting and non-woven fabric.Woven and knitting
Fabric is made by yarn or long filament by weaving process；Non-woven fabric (also known as non-woven fabrics) is by textile fabric through viscous
It closes, fusion or other machinery, chemical method are process.Woven fabric is that warp thread is mutually perpendicular to weave in weft yarn and is formed
Fabric, fabric tissue have plain weave, twill, satin weave and by above-mentioned three kinds of elementary organizations and by its hand over phase change be formed by group
It knits.Knitting fabric is yarn or long filament to be constituted coil, then coil is mutually gone here and there and is covered, since the loop construction of knitted fabric is special
It levies, yarn storage amount is more in unit length, therefore has good elasticity mostly.Woven and knitting belongs to traditional textile processing model
Farmland, traditional textile are using first spinning, rear weaver's sequence, specific woven step：Staple in bulk shredding removal of impurities, mixing, combing, combing, one
Road drafting, rove, spun yarn, winder, warping, sizing, wears tying-in, weft preparing, weaving at two draftings；Specific weft-knitting step
Suddenly it is：Staple in bulk shredding removal of impurities, mixing, combing, combing, one of drafting, two draftings, rove, spun yarn, winder, thermal finalization, latitude
Needle is knitted.In traditional textile processing, there are three big technical problems：Traditional ring spinning is processed into process needed for yarn by staple in bulk first
More, long flow path, recruitment are more, time-consuming more, of high cost, and efficient matter short route spinning is the basis for solving to shorten textile flow；Second,
It spins the weaving preparation after spinning process and weaving process flow is longer, the speed of service is high, to yarn abrasion, intensity, filoplume etc.
Quality requirements are higher, and Yarn filoplume easily causes hosiery yarns around crochet hook broken needle more or woven opening is unclear so that wefting insertion efficiency drops
Low, yarn abrasion and intensity is low leads to that woven warp end break frequency is high, weaving efficiency is low, end product quality is poor；Third, although
Traditional ring spinning yarn resultant yarn cohesive force is high, spun size range is wide, but spins by factors such as fibre length, rigidity, number of fiber
Restriction, especially fibre length is too short (length be less than 20 millimeters), during resultant yarn the inside and outside transfer cohesive force of fiber it is insufficient, at
Yarn strength is low, breakage is frequent, can not continuous spinning.
To solve the problems, such as that traditional ring spinning yarn process flow is grown, various free end high-speed spinning technologies are come into being.Whirlpool
Stream spinning is to utilize fixed vortex spinning spool, and the rotor and Yarn-spinning spindle, wire loop to replace revolution at a high speed carry out
A kind of spinning method of spinning.Due to vortex replace machinery twisting and cohesion without revolution parts,
Thus there are the advantages such as speed is fast, yield is high, technological process is short, row yielding is high.But air-jet eddy-current spinning is pushed by being vortexed
Free end yarn tail is made annular revolution at a high speed and is twisted and resultant yarn, belongs to the non-gripping spinning in free end, causes in spinning process to fiber
Curable grip it is insufficient, metastasis degree is low inside and outside fiber, and fiber obvolvent degree is poor, and spinning strength is relatively low, therefore obvolvent force difference, length
Short, rigidity can not all carry out vortex spun yarn greatly, with the fluffy fiber of bending.Friction spun yarn is that a kind of technological process is short, sets
Standby simple, low speed high yield Yarn spinning method, is combined with air with machinery and carrys out adsorption-condensation fiber, in the same of adsorption-condensation fiber
When, rubbing is carried out to yarn by revolution dust cage friction roller by frictional force and twists resultant yarn.But FRICTION SPINNING yarn is that layer twists looping knot
Yarn is constituted, lacks inside and outside transfer between yarn interior fiber, obvolvent force difference between fiber, yarn strength is low.Therefore, when fiber is curved
When stiffness is big, length is too short, dust cage afterturn can not effectively turn bent, winding and twisting resultant yarn, friction spun yarn resultant yarn difficulty is big, at
Yarn quality is low.Raw materials used rotor spinning is the thick item of fiber, is different from rove used when ring spinning, is not required to thin by multiple tracks
The drawing-off and combing of cause can be fed directly into rotor spinning machine and carry out rotor spinning, and rotor spinning rotor spinning rotor spinning
Twisting separates progress with winding, and spinning speed is not influenced by yarn package, and revolving cup velocity of rotation is high, therefore rotor spinning has
Spinning speed is high, big, at low cost, the advantages such as low to ingredient requirement are wrapped.But rotor spinning mechanism is that fiber is free in sliver
End resultant yarn in such a way that overlapped, easily causes that be overlapped on the control force that the fiber of yarn volume surrounding is subject in spinning process small, causes to turn
It is poor that cup spinning holds forming control ability to fiber, be not suitable for obvolvent force difference, length is short, rigidity is big, with the fluffy fibre of bending
Dimension spinning.In conclusion compared with traditional ring spinning yarn technology, each open-end-spinning greatly improves spinning speed, by taking
Roving Frames disappear to shorten flow；But open-end-spinning can not still be avoided being combed into the conventional processes such as item, combing, drafting, flow
Still longer, and free end Spinning principle determines that resultant yarn cohesive force is insufficient, yarn strength is low, obvolvent force difference, length is short, rigidity
Greatly, with fluffy difficult spinning fiber with cannot the carrying out continuous effective high-quality open-end-spinning of bending.
During solving traditional ring spinning, open-end-spinning, fibre length is too short (length is less than 20 millimeters), resultant yarn mistake
The inside and outside transfer cohesive force of fiber is insufficient in journey, yarn strength is low, breakage is frequent, can not continuous spinning the technical issues of, often
Using long filament, the compound resultant yarn method of staple fiber.China Patent Publication No. CN101492843B, publication date on May 12nd, 2010, invention
Create a kind of entitled positioning spinning method of embedded system, embedded spin is by two root long silks with a determining deviation disclosed in the complicated legal case
Front roller is fed, two root items are symmetrically fed into front roller with a determining deviation respectively, forms long filament and the side of side
Then the first pre- looping of staple fiber yarn carries out converging twisting with the complex yarn yarn after the pre- looping in the other side, forms structure again
More complicated complex yarn；The embedded yarn formation zone spun is the resultant yarn that long filament forms big symmetry acute triangle shape
Area, two root items are fed into the resultant yarn area of the acute triangle of long filament composition so that long filament can have staple fiber yarn
Automatic contact of effect winds with catching type, extends fiber-spinnable type, yarn count range, realizes that difficult spinning fiber strip can
It is smoothed out RING SPINNING resultant yarn.China Patent Publication No. CN103215700B, publication date on 01 06th, 2016, innovation and creation name
Referred to as a kind of vortex compound spinning method producing fancy yarn substantially discloses a kind of carrier long filament and is clamped with staple fiber
Formula air vortex spinning, effectively captures staple fiber so that the fiber of short length can be effectively spun into yarn body, and it is short to realize difficult spinning
Fiber strip can be smoothed out vortex spun yarn.Although it is above-mentioned can solve to a certain degree it is difficult spin fiber can not resultant yarn ask
Topic, but above-mentioned technology does not obtain large area use, key is that above-mentioned technology still uses ribbon or rove as correspondence
Process raw material, exactly superbhort fiber, high rigidity fragile fibre, high spring back that super fluffy fiber, pulverulent material etc. are difficult to spin raw material hardly possible
To produce ribbon or rove.It can be seen that by superbhort fiber, high rigidity fragile fibre, the super fluffy fiber of high rebound, powdery
The cylindric cohesion style linear body that the difficult spinning raw material such as difficult spinning raw material such as material is directly prepared into longitudinal ordered arrangement is extremely difficult, therefore
Short route produces superbhort fiber, high rigidity fragile fibre, the high hardly possible such as super fluffy fiber, pulverulent material that springs back and spins the continuous of raw material
Linear body, the spinning unit for embedded fiber is efficiently clamped use, and are the key that solve the difficult raw material that spins smoothly to spin.
It is non-woven no longer to need spinning, woven fabric process, only fiber or long filament are oriented or random alignment, formation are fine
Then web frame forms non-woven fabrics using the methods of mechanical, hot sticky or chemical reinforce；Yarns interwoven, woollen yarn knitting with one one
The traditional textile processing for forming fabric together is compared, and non-woven cloth is usually that one-step method is completed (as used polypropylene granules
For raw material, batch continuous one-step through high-temperature fusion, spinneret, paving guiding principle, hot pressing and produce polypropylene non-woven fabric), breach biography
System weaving principle, has the advantages such as technological process is short, throughput rate is fast, and yield is high, at low cost, purposes is wide, raw material sources are more.Root
According to non-woven key technology method difference, it is broadly divided into：Spun lacing method, needle point method, meltblown, spun-bond process, calendar bonding process, loop bonding
Method, composite algorithm etc..Spun lacing method is so that fiber is mutually become entangled in one by high pressure fine water flow jet to one or more layers web
It rises, has certain strength to enable fibre web to reinforce, it is different according to the product quality requirement processed, it is divided into two kinds of techniques
Route：A. fibrous raw material → shredding mixing → combing → lapping → drawing-off → prewet (water process cycle) → positive and negative spun lacing is (at water
Reason cycle) → final finishing → drying → winding；B. fibrous raw material → shredding mixes → combs disordered wet forming → prewetting, (water process is followed
Ring) → positive and negative spun lacing (water process cycle) → final finishing → drying → winding.Flow A to fibre web vertically and horizontally strength ratio adjusting compared with
It is good, it is suitable for production spunlaced synthetic leather substrates；Flow B is suitable for production spun lacing and defends material.Needle point method is the one of dry method nonwoven forming
Kind, it is to be acted on using the puncture of pricker, fluffy fibre web is reinforced into cloth.Meltblown is in extruded polymer method nonwovens process
One kind, technique original is that the polymer melt stream squeezed out to die head spinneret orifice using high velocity, hot air carries out drawing-off, thus
It forms superfine fibre and condenses upon on solidifying lace curtaining or roller, and rely on and itself be bonded as non-woven cloth, specific embodiment
For：Polymer is fed, and -- -- fiber is formed, and -- fiber cooling -- networking -- is reinforced into cloth for melting extrusion.Spun-bond process is also that melting is spun
Silk networking method belongs to one-step method into cloth nonwoven techniques, it is the method using chemical fibre spinning, in polymer spinning technique
The melt filament of extrusion is cooled down by the air of quenching in the process, filament is made to be stretched air-flow work in cooling procedure
With, formation continuous filament yarn, the then networking on solidifying lace curtaining, and be laid in on lace curtaining, then formed and spun after consolidation device is handled
Bonding non-woven cloth.To realize multigroup part, various nonwoven fabric composite performances, frequently with composite algorithm nonwoven techniques, such as：SM、
(S represents that spun-bond process is non-woven, M represents melt blown nonwoven, C represents hot calendering bonding to the complex forms such as SMS, SMSMS, CS, CSC
Method is non-woven).As fibrous material is in the continuous development of each field application technology, nano-fiber material becomes research and function is answered
Hot subject.Nanofiber diameter is within the scope of 1nm-100nm, has porosity height, large specific surface area, draw ratio
Greatly, surface energy and the high performance advantage of activity, embody the functions such as excellent enhancing, antibacterial, water repellent, filtering, apply and detaching
Each field such as filtering, biologic medical, energy and material, enhancing by polymer, photoelectric sensing.With the extension of nanofiber application field
And demand, the forming technology of preparing of nanofiber have also obtained further exploitation and innovation；Up to the present, the system of nanofiber
Preparation Method includes mainly chemical method, phase separation method, self-assembly method and spinning processing method etc..And spinning processing method is considered as scale
Change prepares the most promising method of high polymer nano fiber, includes mainly method of electrostatic spinning, two-component composite spinning method, meltblown
With laser pulling method etc..Wherein laser ultrasonic pulling method is to heat fiber using laser irradiation, while in Ultrasonic Conditions
Under it is stretched, generate about 105 times of draw ratio, prepare nanofibers, belong to a kind of conventional filament post-processing
Method；In addition to this, other nanometer spinning process are also all directly related to spinning head, have in common that：It is assisted using spinneret
It is acted on drawing-off so that fibre diameter reaches nanoscale.China Intellectual Property Office's invention disclosed on November 11st, 2016 is special
