Description

A kind of device of gradient wrap yarn filoplume
Technical field
The present invention relates to a kind of device of gradient wrap yarn filoplume, belong to technical field of textile processing.
Technical background
Filoplume is to weigh one of important indicator of yarn qualities.Yarn filoplume not only affects the rear operation such as woven, knitting Production efficiency, and affect the presentation quality of final products, particularly high speed shuttleless loom commonly used today, reduce yarn Filoplume tool is of great significance.
Yarn filoplume results from spun yarn manufacturing procedure, its mechanism be inside and outside transfer fiber head end expose yarn body after, take off Gripping from jaw acts on it is impossible to being again introduced into or being wrapped on yarn body trunk, forms filoplume.Filoplume increases in winder and warping Operation, its basic reason is: yam surface filoplume is many, structural relaxation, in the yarn high-speed cruising operation such as winder, warping, Yarn, through parts such as yarn guide member, tension parts, is rubbed by fierceness, causes fiber head end serious withdrawing in portion's in yarn body to be free on Yarn body surface face, filoplume increases severely, surface structure heavy damage.In order to reduce Yarn filoplume, realize yarn and smoothly weave, textile enterprise General all yarn after warping is carried out with sizing process, attach Yarn filoplume, yarn is carried out strengthening simultaneously guarantor stretch, increase wear-resisting Property.But warping generally adopts piece yarn starching, and it is inter-adhesive that piece yarn starching may result in yarn, needs wet, dry leasing, yarn leasing When mutually tear destruction yarn body surface starch adhesive film, produce secondary filoplume.As can be seen here, eliminate Yarn filoplume, increase yarn top layer knot Structure consistency should be carried out before starching.
For ring spindle yarn operation, scholar both domestic and external does excessive quantifier elimination.The approach generally adopting has two kinds, a kind of It is that common ring spinning process is optimized using conventional method, the method can only reduce Yarn filoplume, action effect to a certain extent Limited;Another kind is to eliminate filoplume using Advanced Spinning Technologies or special elimination filoplume device, and ring spun yarn can be greatly lowered Line filoplume.New ring spinning technology or special elimination filoplume device are the focuses of current ring spinning technical research.New at present It is Advance of Compact Spinning Technology that type ring spinning technology represents, such as Department of Intellectual Property of the U.S. on December 18th, 1984 invention disclosed patent “device for stretching,condensing and transporting a rove of fibers during a Spinning operation ", patent No. us 4488397;Department of Intellectual Property of the U.S. on June 13rd, 2000 invention disclosed is special Sharp " device for condensing a drafted fiber strand ", the patent No. 6073314;Department of Intellectual Property of the U.S. On June 13rd, 2000 invention disclosed patent " device for condensing a drafted fiber strand ", specially Profit number 6073314;Department of Intellectual Property of the U.S. on July 4th, 2000 invention disclosed patent " arrangement for Condensing a drafted fiber strand ", the patent No. 6082089;On Department of Intellectual Property of U.S. January calendar year 2001 9 is public The patent of invention " transport belt for transporting a fiber strand to be condensed " opened, Patent No. us 6170126b1;24 days Department of Intellectual Property of U.S. July calendar year 2001 invention disclosed patent " arrangement and method for condensing a drafted fiber strand and method for making yarn Thereform ", patent No. us 6263656b1;Department of Intellectual Property of U.S. calendar year 2001 August invention disclosed patent on the 14th " apparatus for condensing a drafted strand ", patent No. us 6272834b1;Department of Intellectual Property of the U.S. May 29 calendar year 2001 invention disclosed patent " condensing zone for a spinning machine ", patent No. us 6237317b1.The central principle of above-mentioned Advance of Compact Spinning Technology patent complicated legal case is all needle ring ingot spinning process, compact spinning trigonum Fiber strip, strengthens fiber strip edge fibers are controlled, and effectively reduces spinning process fiber head end and exposes, reduces yarn hair Plumage;But compact spinning eliminates spinning triangular zone, not, cohesive force is not enough for the inside and outside transfer of yarn body internal fiber, and outer layer still has filoplume to reveal Go out, after yarn body stands friction, filoplume still increases severely;Particularly at present by the Advance of Compact Spinning Technology of airflow concentration, only to high grade cotton yarn Filoplume reducing effect is substantially, poor to thick spy's Yarn filoplume reducing effect.
The special reduction filoplume device using at present is using jet-impingement form, be arranged on front roller and twizzle it Between, make established filoplume patch volt in yam surface using the revolution of air-flow, such as Department of Intellectual Property of the U.S. on April 10th, 1979 is public The patent of invention " method and apparatus yarn treatment " opened, the patent No. 41481779, U.S.'s intellectual property Office August in 1989 invention disclosed patent " method and apparatus for modifying spun textile on the 22nd Yarn ", the patent No. 5263311.These researchs main difference is that and lead to yam surface fine due to the difference of airflow injection device Dimension Impact direction is different, thus producing different winding effects and leading to the difference of Yarn filoplume eradicating efficacy.But due to this A little devices can be only installed at twist triangle zone after (because the fiber in twist triangle zone becomes staple in bulk shape, the air-flow of injection substantially Fiber movement can be led to chaotic and break end), it is yarn and yam surface filoplume that its air-flow brushes object, brushes being bullied of two objects Flow rotation effect difference, realizes for filoplume staying yam surface in the form of simple patch volt and lax winding;In later process (such as Winder) processing in, parts rub withdrawing yarn surface structure fiber, lax docile and be wound around filoplume again reveal, Do not reach the real effect eliminating filoplume.
For winding procedure high-speed friction, cause yam surface structural damage, filoplume increases in a large number, strength decline it is desirable to Supporting sizing operation, increases the problems such as starching difficulty and sizing cost, arranges filoplume flattening device in winding procedure, suppresses filoplume Generation, to later process produce and improve end product quality tool be of great significance.The minimizing studied at present The method of resultant yarn filoplume is concentrated mainly on minimizing Winding yarn filoplume device;Although Patents documents have a lot, adopt General principle is identical, carries out backtwisting-twisting mode using to advancing yarn in yarn on bobbin-winding machine, makes yam surface Filoplume, wound on yam surface, reaches the purpose reducing filoplume.Representational patent document has: european patent number is ep 0 866 014 a2, publication date on 09 23rd, 1998, invention and created name is auto winder, and this application complicated legal case adopts winding process Turn round the mechanism of navel in flow process, make wandering fibre along the sth. made by twisting of yarn to patch volt to next with yarn, to reduce yarn hair Plumage;U.S. Patent No. us 6 374 588 b1, publication date on 04 23rd, 2002, invention and created name is hairiness Controlling device and winder, this application complicated legal case adopts the machinery work of revolution navel in winding process flow process With making wandering fibre along the sth. made by twisting of yarn to patch volt on yarn body trunk, to reduce Yarn filoplume;European patent number is ep 1 146 002 a2, on publication date October calendar year 2001 17, invention and created name is automatic winder and hairiness Suppressing device, this application complicated legal case utilizes air vortex flow tube, by the mechanical function of swirling eddy, makes filoplume again It is coated to yarn, to reduce filoplume, but analyzes from principle, only according to the looping effect of air-flow, its covered effect is bad;Europe Patent No. ep 1 013 803 a2, publication date on 06 28th, 2000, invention and created name is hairiness Suppressing device for automatic winder, this application complicated legal case equally using air vortex flow tube, by air-flow So that yarn is rotated, when the yarn of rotation is when control panel (regulating plate), so that fiber is wrapped over yarn, to subtract Few filoplume;China Patent No. is zl 99127507.1, publication date on 07 05th, 2000, and invention and created name is automatic winding The filoplume flattening device of machine, this application complicated legal case equally using air vortex flow tube, makes yarn rotate by air-flow, but this patent is led to Cross and install controller additional at device two ends, produce false twist effect to ensure that yarn turns round along own axes, improve and reduce Yarn filoplume Efficiency.In addition, China Patent No. is zl 200710052991.8, publication date on 01 23rd, 2008, innovation and creation name Referred to as a kind of method reducing resultant yarn filoplume, by the way of this application complicated legal case provides a kind of flatiron using false twisting, to winder and knitting The yarn of process is attached and wrap yarn filoplume online, and few part filoplume is involved in yarn body, realizes winder or knitting process The mesh that middle suppression Yarn filoplume increases.The method and apparatus of above-mentioned minimizing yam surface filoplume, has in common that Yarn filoplume By air-flow or mechanical type lodging, be again wrapped over yarn do on;But during whole filoplume flattening, again looping, all do not have Actively gripping effect effectively, filoplume flattening, again looping are loosely organized, and yarn top layer densification degree does not improve, and reduces Filoplume stand friction and be easy to rebound again;When filoplume is wound into yarn body simultaneously, because of fibril aggregation, the yarn reducing after filoplume is thick The yarn defect such as section, cotton knot is significantly increased.
Above-mentioned as can be seen here use the Yarn filoplume of process to control on winder, warping, the yarn such as knitting, existing method is common Point is: in the case that non-positive grips filoplume head end, yarn is carried out with false twisting or air-flow brushes looping, will stretch out yarn table Most filoplumes in face are wound with loosely form, docile cannot be formed between yarn face, filoplume fiber and yarn body Fine and close structural nexus, only visually realizes filoplume and reduces;For in the form of backtwisting-twisting, attach filoplume process In, the yarn local twist is subject to dynamic transfer and redistribution, the weaker position of the twist, deteriorated by yarn tension stretching The yarn body trunk uniformity.More it is essential that in later process, being rubbed by parts with yarn, these lax winding, patches Clothes are easy to stretch out yam surface formation filoplume, the processing to yarn later process and final product again in the fiber of yam surface The quality (especially knitting product quality) of product does not have essence improvement.
For the problems referred to above, China Patent No. is zl 201410204503.0, publication date on 05 15th, 2014, invention Create a kind of rotary method improving yarn surface structure of entitled positive gripping, this application complicated legal case provides one kind to adopt negative pressure Absorption grips yarn top layer filoplume, rotatably winds around gripping filoplume on yarn trunk simultaneously;But this negative-pressure ward There is following technical problem in the method gripping rotation looping filoplume: first, because taper gripping surface upper all had along the whole week Have negative pressure gripping act on, to more thick and stiff, simultaneously filoplume with compare fragile easily short Yarn filoplume at yarn body Truck Connection, process During often block mesh on taper gripping surface because of the thick and stiff fiber of fracture, along with workshop flyings docile is on mesh, Fiber on mesh for these dociles cannot be centrifuged and throw away and remove, and cause taper gripping surface that the gripping of yam surface is acted on big Weaken greatly, even lose it is impossible to meet the effect of the gripping wrap yarn surface hairiness of continuous and effective;Second, filoplume is wound into During yarn body, at winding in the way of perpendicular to yarn trunk high-speed rotation be wound into yarn do on, not only filoplume is failed with relatively Big pitch is wrapped on yarn body, cannot greatly improve yarn strength, and Yarn filoplume is often because of the gathering winding on yarn body, The yarn defect such as yarn slubbing, cotton knot is caused to be significantly increased, corresponding appearance of fabrics fault also increases;3rd, taper gripping surface rotates One week, filoplume can only being wound around on yarn body a circle, if improving filoplume looping efficiency, needing taper gripping surface rotation is substantially improved Rotary speed, increases energy consumption and rotary part abrasion, does not still enable the efficient winding yarn filoplume work(under low rotary part effect Energy;4th, due to the taper gripping surface using single negative pressure and rotary speed, yam surface filoplume is carried out with negative pressure and grips bag Twine, tightness identical disposable filoplume looping can only be carried out to filoplume it is impossible to realize the skill of the laddering complete looping of tightness gradient Art effect.

rotation, and heat setting device is heated by external power supply so that pressing yarn bath temperature degree liter To 135 DEG C, the taper between the upper end cone wall 12 of hollow out cone 11 and the lower end cone wall 14 place conical surface and quill shaft 15 cross section is 3:1, upper end cone wall 12 wall wide is 20 millimeters, and outer convex cone wall 13 width is 15 millimeters, 10 millimeters of lower end cone wall 14 wall wide, all cones The grid through-hole diameter of the grid through hole on wall and quill shaft 15 upper end wall is 2 millimeters, and the outlet side 3 of orientation aspiration channel is external Negative pressure air exhauster, the grid through hole on all cone walls to hollow out cone 11, the grid through hole of quill shaft 15 upper end wall implement negative pressure Suction.In 25 DEG C of environment, using plasma atomising device implements atomization to the aqueous solution containing 5% cationic softener, right Ne60 English props up cotton yarn and carries out damp state process so that the cotton yarn regain after processing is more than 15%, softening yarn fiber;Chao Taichu When cotton yarn after reason carries out warping, ne60sMany filoplumes cotton yarn (z sth. made by twisting) is with 600 ms/min of speed from being placed in bobbin cradle Package unwinds, with tensioning state successively through tensioner, yarn guide member, via the first yarn guiding wheel of yarn gatherer 17th, the second yarn guiding wheel 21, is run, cotton yarn runs in the way of guide-roller type low friction in the hollow out cone 11 of funneling rubbing device To before the internal face of the lower end cone wall 14 of hollow out cone 11, in the grid through hole negative pressure draft effect of quill shaft 15 upper end wall Under, cotton yarn surface hairiness obtains directional stretch, promotes Yarn filoplume to be oriented direction of extension with yarn traffic direction in about 45 angles, the cotton yarn of surface hairiness directional stretch runs to the lower end cone wall 14 of the hollow out cone 11 of high-speed rotation, wall at this The effect of grid through hole negative-pressure ward makes filoplume be gripped, and cotton yarn trunk is under lower end cone wall 14 rubbing action of high-speed rotation Rotated, promote cotton yarn surface hairiness orientation to be wrapped on cotton yarn trunk, prevent filoplume at random or vertical wrap is to yarn master Tangle into cotton knot when dry, it is to avoid fibril aggregation, efficiently solve and produce the yarn defect such as yarn slubbing, cotton knot because of fibril aggregation significantly Increased technical barrier;The cotton yarn that filoplume orients looping runs to outer convex cone wall 13 notch, by outer convex cone wall 13 surface mesh Under lattice through hole negative pressure draft effect, the filoplume of the incomplete looping in cotton yarn surface obtains directional stretch, filoplume directional stretch side again To in about 45 ° of angles, the cotton yarn of looping filoplume directional stretch completely does not run engraving to high-speed rotation with yarn traffic direction At the upper end cone wall 12 of sky cone 11, at this, wall effectively grips the cotton of the incomplete looping of directional stretch under negative-pressure ward effect Yarn hair plumage, cotton yarn trunk is rotated under upper end cone wall 12 rubbing action of high-speed rotation, promotes the incomplete looping of cotton yarn Filoplume is completely wound around on cotton yarn trunk, because the linear velocity at upper end cone wall 12 is noticeably greater than the linear speed at lower end cone wall 14 Degree, slewing rate and great efforts that the rubbing action of upper end cone wall 12 produces to cotton yarn trunk, the suffered bag of cotton yarn surface residual filoplume Twine great efforts, looping more abundant, it is achieved thereby that the laddering gradient complete looping effect of cotton yarn surface hairiness;Due to hollow out cone 11 rotate a circle, and Yarn filoplume rotation looping many weeks are it is achieved that the effect of high-speed and high-efficiency complete wrap yarn filoplume.Through hollow out cone Yarn after the complete looping filoplume of 11 laddering gradients, the flatiron entering heat setting device immediately is walked in yarn groove, is squeezed by slot type Pressure and high temperature heat setting action, increase Yarn filoplume looping structural stability and structural compactness further, solve conventional fall In filoplume technology, yarn top layer filoplume winding arrangement relaxes, the technical problem of Yarn filoplume bounce-back in postorder process.Cotton yarn Walk yarn groove through flatiron to carry out, after structure thermal finalization process, being exported by the 3rd yarn guiding wheel 5 of yarn let-off gear(stand), then successively through stretching Contracting button, cord roller, are finally wound up on warp beam.Contrast test result shows: using the cotton yarn hair after the inventive method warping Plumage total amount reduced rate is 96.1%.
