Description

A kind of method that down-like difficulty spins the compound resultant yarn of fiber short route

Technical field

The present invention relates to a kind of methods that down-like difficulty spins the compound resultant yarn of fiber short route, belong to textile technology field.

Background technology

It can be divided into three categories for the textile fabric of clothes：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 through viscous by textile fabric 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 has plain weave, twill, satin weave and hands over the group that is formed of phase change by above-mentioned three kinds of elementary organizations and by it It knits.Knitting fabric is yarn or long filament to be formed 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 process as needed for staple in bulk is processed into yarn 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, it is wide to spin size range, but spins by factors such as fibre length, rigidity, number of fiber Restriction, particularly 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, into 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 long, various free end high-speed spinning technologies are come into being.Whirlpool Stream spinning is using fixed vortex spinning spool, the rotor of revolution at a high speed and Yarn-spinning spindle, wire loop to be replaced to carry out A kind of spinning method of spinning.Due to replacing the parts of mechanical twisting and cohesion without revolution with vortex, 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 non-hold in free end and spins, 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 twisting resultant yarn is carried out to yarn by revolution dust cage friction roller by frictional force.But FRICTION SPINNING yarn twists with the fingers looping knot for layer Yarn is formed, 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, into Yarn quality is low.Rotor spinning is raw materials used for the thick item of fiber, different from ring spinning when rove used, be not required to thin by multiple tracks The drawing-off and combing of cause carry out rotor spinning, and rotor spinning rotor spinning rotor spinning with regard to that can be fed directly into rotor spinning machine 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 free in sliver for fiber End resultant yarn in a manner of overlapping, 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 to fiber gripping forming control ability that cup spins, and is not suitable for the fibre that obvolvent force difference, length is short, rigidity is big, has bending fluffy 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 It is still longer, and free end Spinning principle determines that resultant yarn cohesive force is insufficient, yarn strength is low, and obvolvent force difference, length are short, rigidity Greatly, have and be bent fluffy difficult spinning fiber with cannot carrying out continuous effective high-quality open-end-spinning.

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 A kind of entitled positioning spinning method of embedded system is created, embedded spin disclosed in the complicated legal case is with a determining deviation by two root long silks 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 of opposite side, forms structure again More complicated complex yarn；The embedded yarn formation zone spun forms the resultant yarn of big symmetry acute triangle shape for long filament 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 for 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 above-mentioned technology still using 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 is used for the spinning unit for efficiently clamping embedded fiber, is 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 uses the methods of mechanical, hot sticky or chemical to reinforce into non-woven fabrics；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 using 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 by high pressure fine water flow jet to one or more layers web, and fiber is made mutually to become entangled in one It rises, has certain strength so as to which fibre web be enable 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, suitable for producing 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 using high velocity, hot air to die head spinneret orifice 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：-- -- fiber is formed, and -- cloth is reinforced into fiber cooling -- networking -- for melting extrusion for polymer feeding.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, continuous filament yarn is formed, the then networking on solidifying lace curtaining, and being 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 should Hot subject.Nanofiber diameter is in the range 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 mainly includes 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, mainly including method of electrostatic spinning, two-component composite spinning method, meltblown With laser pulling method etc..Wherein laser ultrasonic pulling method is to heat fiber, while in Ultrasonic Conditions using laser irradiation 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 Sharp " controllable screening electrostatic spinning nano fiber film of multiple response and preparation method thereof ", number of patent application ZL201611005678.4, this application complicated legal case provide a kind of by Thermo-sensitive and PH responsive polymers solution merging electrostatic spinning Instrument, the method for forming nano fibrous membrane through electrostatic spinning machine injection placed.The critical issue of Static Spinning is that electrostatic spinning belongs to Non-positive grab tensile spinning, electrostatic jet stream form taylor cone in filamentation process, and jet stream fiber is difficult to carry out effective high power Drawing-off, drawing-off deficiency cause in nanofiber that macromolecular oriented degree is poor, nanofiber fineness needs further to be refined, strength Too low and scale needs further to be refined；In addition the filamentation process of taylor cone form causes fiber obtained by Static Spinning that cannot be indulged To orderly row's placed, it is difficult to spun fiber linearly be collected and be gathered, mainly for the production of micro/nano fibrous membrane material.China A kind of on 08 29th, 2016 invention disclosed patents " coaxial eccentricity device for spinning and method " of Department of Intellectual Property, number of patent application ZL201610753443.7, this application complicated legal case provide a kind of by multilayer syringe needle inside and outside being set on coaxial eccentricity pipe, realization The centrifugal spinning method of high speed rotation coaxial eccentricity pipe progress large-scale production superfine fibre, even nanofiber；Chinese knowledge " a kind of titanium dioxide/Kynoar is micro-/receives tunica fibrosa and its centrifugation to property right office invention disclosed patent on December 14th, 2016 Electrospinning method for preparing ", number of patent application ZL201611154055.3, this application complicated legal case provide a kind of by homemade Detitanium-ore-type Both TiO2 and Kynoar (PVDF) mix the centrifugal spinning solution produced, and centrifugal spinning is carried out on centrifugal box-spinning machine, The method of micro-nano fiber film is made.The critical issue that centrifugation is spun is that, by high speed rotation centrifugal action spinneret, that is sprayed penetrates Silk is flowed into correspondingly in circular ring type placed into silk, it is difficult to spun fiber is subjected to longitudinal ordered arrangement, linear collect and gather, master It is used to produce micro/nano fibrous membrane material；During centrifugal spinning, non-positive grab tensile spinning is also belonged to, centrifuges jet stream drawing-off Power is restricted by factors such as rotating speed, air drag, and the drawing-off for leading to spinning is insufficient, and drawing-off deficiency causes macromolecular in nanofiber to arrange The row degree of orientation is poor, nanofiber fineness needs further to be refined, and strength is too low and scale needs further to be refined.But nanofiber Diameter is too small, causes nanofiber absolutely strength too low, easy to wear, comes off coated in fabric surface is easy to wear, there is coating and spin Fabric products function persistence is poor, causes nanofiber that can only carry out lapping on a small quantity and is processed into nano fibrous membrane, and can not carry out often The drawing-off of rule, twisting resultant yarn, the serious industrial applications for restricting nanofiber.Nanofiber is such as processed into macroscopic view, can be adopted The products such as medical types of functionality, function clothes, industrial fabric are produced with modern textile means, traditional textile products will be broken through It can and be worth, have a extensive future.Therefore, drawing-off deficiency causes macromolecular oriented in nanofiber in nanometer spinning production Poor, the nanofiber fineness of degree needs further to be refined, strength is too low and scale need further to be refined cause again adherency with it is durable Property it is poor, coated in fabric surface it is easy to wear come off, be unable to conventional spinning processing, cause nanofiber textile industry metaplasia produce In, non-woven fabrics or nanometer film can only be processed into, high speed short route textile process can not be carried out, the serious weaving for restricting nanofiber Industrial applications.It can be seen that not only process flow is very short for the non-woven networking of nonwoven or film-forming process, and be particularly easy to by Various superbhort fibers, high rigidity fragile fibre, the high difficult difficult raw material that spins such as raw material that spins such as super fluffy fiber, pulverulent material that springs back are made Meet the planar or scale aggregate of intensity needed for postorder processed and applied, assign the higher intensity of product, fluffy degree, flexibility, Gas permeability and hydrophily.But nano fiber non-woven film, there are following defects for conventional fineness fiber non-woven cloth：1) non-woven fabrics is strong Degree and durability are poor, can not compare favourably with traditional textile cloth, it is impossible to be used instead of traditional textile dress-goods；It 2) cannot be as it He equally cleans cloth, it is difficult to for garment material；3) fiber arranges, easily splits from right angle orientation in certain direction.Therefore By superweak (nanofiber etc.), ultrashort (short flannel), high rigidity brittleness (carbon fibre, glass, quartz fibre etc.), the high super bulkiness of rebound The hardly possible woven material system such as (down-like fiber), powdery (fibrous crystal palpus, carbon nanotube, graphene, various nanoparticles, nano-particle) Into the planar or scale aggregate of nonwoven film or non-woven cloth, then planar or scale aggregate are quickly converted to and spun with tradition Fabric increases fabric intensity and durability, while retains the performances such as fluffy, ventilative, the soft, antibacterial of nonwoven film, non-woven cloth, is Solve nonwoven film, Nonwovens In Technology shortcoming, the key for expanding non-woven products that application field.

For the key problem in technology, China Patent Publication No. CN202247124U, publication date on May 30th, 2012, invention wound Make a kind of non-woven fabrics flat bar flame of entitled two-way cladding, the yarn by a non-woven fabrics flat bar as heart yarn, two The two-way cladding heart yarn of monofilament, wherein non-woven fabrics flat bar do not twist obvolvent, only external sheath long filament, are substantially a kind of fancy Line, it is totally different with tradition twisting obvolvent yarn texture；China Patent Publication No. CN2670389Y, publication date on 01 12nd, 2005, Invention and created name is a kind of bulky yarn made from nno-weavon fabrics, which is the flat-shaped pressure of continous way that the hot pressing of non-woven fabrics longitudinal direction is formed Item, this presses against item fiber itself and tends to longitudinal arrangement, and hot pressing softening is binded into dense state, and presses against two outside of item and have There is the fluffy fiber hair not pressed against.Obviously, although LINEAR CONTINUOUS spy of the yarn with certain strength that above two complicated legal case provides Sign, but yarn shape structure is flat bar state, lacks fiber twisting cohesion style cylindrical structure, it is widely different with conventional textile yarn texture It is different, it is not suitable with conventional textile equipment and walks yarn and yarn-guiding duct, it is impossible to veritably incorporate conventional batch yarn weaving equipment and life Production. art does not solve superweak (nanofiber etc.), ultrashort (short flannel), high rigidity brittleness (carbon fibre, glass, quartz fibre Deng), high spring back that super bulkiness (down-like fiber), powdery (carbon nanotube, graphene, various nanoparticles, receive by fibrous crystal palpus Rice corpuscles) etc. difficult woven material the technical issues of how being spinned, being weaved, therefore superbhort fiber is generally used for papermaking at present Industry, the strengthening filler of composite material, flocking products exploitation.
