Description
Technical field
The utility model relates to the rotary device that improves yarn surface structure of a kind of positive gripping, belongs to technical field of textile processing.
Technical background
Filoplume is one of important indicator of weighing yarn qualities.Yarn filoplume not only affects the production efficiency of the rear operation such as woven, knitting, and affects the presentation quality of final products, today that particularly high speed shuttleless loom is generally applied, reduces Yarn filoplume tool and is of great significance.
Yarn filoplume results from spun yarn manufacturing procedure, and its mechanism is after the fiber head end of inside and outside transfer exposes yarn body, departs from the gripping effect of jaw, cannot again enter or looping on yarn body trunk, form filoplume.Filoplume increases in winder and warping process, its basic reason is: yam surface filoplume is many, structural relaxation, in the yarn such as winder, warping high-speed cruising operation, yarn is through the parts such as yarn guide member, tension part, suffer fierce friction, cause the serious withdrawing of yarn body internal fiber head end to be free on yarn surface, filoplume increases severely, surface structure heavy damage.In order to reduce Yarn filoplume, realize yarn and weave smoothly, textile enterprise generally all carries out sizing processing to yarn after warping, attaches Yarn filoplume, yarn is strengthened to guarantor simultaneously and stretch, increase ABRASION RESISTANCE.But warping adopts the starching of sheet yarn conventionally, the starching of sheet yarn will cause yarn inter-adhesive, needs wet, dry leasing, mutually tears and destroys yarn surface serous coat, produces secondary filoplume when yarn leasing.As can be seen here, eliminate Yarn filoplume, increasing yarn surface structure density should carry out before starching.
For ring spindle yarn operation, scholar both domestic and external did a large amount of research.Conventionally the approach adopting has two kinds, and one is to adopt conventional method to optimize common ring spinning process, and the method can only reduce Yarn filoplume to a certain extent, and action effect is limited; Another kind is to adopt Advanced Spinning Technologies or special elimination filoplume device to eliminate filoplume, can significantly reduce ring spun yarn line filoplume.Novel ring ingot spinning technology or special elimination filoplume device are the focuses of current ring spinning technical research.Novel ring ingot spinning technology representative is at present Advance of Compact Spinning Technology; as Department of Intellectual Property of U.S. invention disclosed patent on December 18th, 1984 " Device for stretching; condensing and transporting a rove of fibers during a spinning operation ", patent No. US 4488397; Department of Intellectual Property of U.S. invention disclosed patent on June 13rd, 2000 " Device for condensing a drafted fiber strand ", the patent No. 6073314; Department of Intellectual Property of U.S. invention disclosed patent on June 13rd, 2000 " Device for condensing a drafted fiber strand ", the patent No. 6073314; Department of Intellectual Property of U.S. invention disclosed patent on July 4th, 2000 " Arrangement for condensing a drafted fiber strand ", the patent No. 6082089; Department of Intellectual Property of U.S. invention disclosed patent in 9 days January calendar year 2001 " Transport belt for transporting a fiber strand to be condensed ", patent No. US 6170126B1; Department of Intellectual Property of U.S. invention disclosed patent in 24 days July calendar year 2001 " 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. invention disclosed patent in 14 days Augusts calendar year 2001 " Apparatus for condensing a drafted strand ", patent No. US 6272834B1; Department of Intellectual Property of U.S. invention disclosed patent in 29 days Mays calendar year 2001 " 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, and compact spinning trigonum fiber strip is strengthened the fiber control of fiber strip edge, effectively reduces spinning process fiber head end and exposes, and reduces Yarn filoplume; But compact spinning is eliminated spinning triangular zone, yarn body internal fiber is inside and outside to be shifted not, cohesive force deficiency, and skin still has filoplume to expose, and after yarn body stands to rub, filoplume still increases severely; Particularly, at present by the Advance of Compact Spinning Technology of airflow concentration, only high grade yarn filoplume is reduced to successful, thick special Yarn filoplume is reduced to weak effect.
The special reduction filoplume device using is at present to adopt jet-impingement form, be arranged between front roller and twizzle, utilize the revolution of air-flow to make established filoplume paste volt in yam surface, as Department of Intellectual Property of U.S. invention disclosed patent on April 10th, 1979 " method and apparatus yarn treatment ", the patent No. 41481779, Department of Intellectual Property of U.S. invention disclosed patent on August 22nd, 1989 " method and apparatus for modifying spun textile yarn ", the patent No. 5263311.These are studied main difference and are to be subject to force direction difference because the difference of jet-impingement device causes yam surface fiber, thereby produce different coiling effects and cause the difference of Yarn filoplume eradicating efficacy.But due to can only being arranged on behind twist triangle zone (because the fiber in twist triangle zone becomes bulk fibre shape substantially of these devices, the air-flow spraying can cause the fiber movement chaotic and break end), it is yarn and yam surface filoplume that its air-flow brushes object, brush the flow rotation effect difference of being bullied of two objects, realize filoplume is stayed to yam surface with the form of simply pasting volt and lax winding; In later process (as winder) processing, the fiber of parts friction withdrawing yarn surface structure, the filoplume of lax docile and winding reveals again, does not reach the effect of real elimination filoplume.
For winding procedure high-speed friction, cause yam surface structural damage, filoplume dramatic growth, powerful decline, require supporting sizing operation, increase the problems such as starching difficulty and sizing cost, at winding procedure, hairiness suppressing device is set, suppress the generation of filoplume, later process production and raising end product quality tool are of great significance.The method of current reducing resultant yarn filoplume after deliberation mainly concentrates on and reduces Winding yarn filoplume device; Although Patents document has a lot, the general principle adopting is identical, on bobbin winder, adopts advancing yarn is carried out to backtwisting-twisting mode at yarn, makes yam surface filoplume be wound on yam surface, reaches the object that reduces filoplume.Representational patent documentation has: european patent number is EP 0 866 014 A2, open day on 09 23rd, 1998, invention and created name is Auto Winder, this application complicated legal case adopts the mechanism of turning round navel in winding process flow process, wandering fibre is come, to reduce Yarn filoplume with it to yarn to pasting volt along the sth. made by twisting of yarn; U.S. Patent number is US 6 374 588 B1, open day on 04 23rd, 2002, invention and created name is Hairiness controlling device and winder, this application complicated legal case adopts the mechanism of turning round navel in winding process flow process, wandering fibre is lied prostrate to yarn body trunk, to reduce Yarn filoplume to pasting along the sth. made by twisting of yarn; European patent number is EP 1 146 002 A2; open day October 17 calendar year 2001; invention and created name is Automatic winder and hairiness suppressing device; this application complicated legal case is utilized air-swirl pipe, by the mechanical function of swirling eddy, filoplume is coated to it yarn again; to reduce filoplume; but analyze from principle, only according to the looping effect of air-flow, its covered effect is bad; European patent number EP 1 013 803 A2, open day on 06 28th, 2000, invention and created name is Hairiness suppressing device for automatic winder, this application complicated legal case is used air-swirl pipe equally, make yarn rotation by air-flow, in the time that the yarn of rotation passes through control panel (regulating plate), make fiber looping with it yarn, to reduce filoplume; China Patent No. is ZL 99127507.1, open day on 07 05th, 2000, invention and created name is the hairiness suppressing device of automatic winder, this application complicated legal case is used air-swirl pipe equally, make yarn rotation by air-flow, but this patent is by adding cartridge controller at device two ends, to ensure that yarn, along self axis revolution generation false twist effect, improves the efficiency that reduces Yarn filoplume.In addition, China Patent No. is ZL 200710052991.8, open day on 01 23rd, 2008, invention and created name is a kind of method of reducing resultant yarn filoplume, this application complicated legal case provides a kind of mode that adopts false twisting flatiron, the yarn of winder and knitting process is carried out to online attaching and wrap yarn filoplume, and few part filoplume is involved in yarn body, realizes the order that suppresses Yarn filoplume growth in winder or knitting process.The method and apparatus of above-mentioned minimizing yam surface filoplume, common ground be by Yarn filoplume by the lodging of air-flow or mechanical type, again looping on yarn is dry; But whole filoplume flattening, again in looping process, all there is no actively gripping effect effectively, filoplume flattening, looping is loosely organized again, and yarn top layer densification degree does not improve, and the filoplume of reduction stands friction and is easy to again rebound.
