A kind of directional stretch cooperates with the device of softening winding yarn filoplume

Technical field

The present invention relates to the device that a kind of directional stretch cooperates with softening winding yarn filoplume, belong to textile process technology neck Domain.

Technical background

Filoplume is one of important indicator of measurement yarn qualities.Yarn filoplume not only influences the rear operation such as woven, knitting Production efficiency, and influence final products presentation quality, 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 is acted on, it is impossible to is again introduced into or is wrapped on yarn body trunk, forms filoplume.Filoplume increases in winder and warping Operation, its basic reason is：Yam surface filoplume is more, structural relaxation, in the yarn high-speed cruising operation such as winder, warping, Yarn is subjected to fierce friction through parts such as yarn guide member, tension parts, 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 that yarn is smoothly weaved, textile enterprise It is general that sizing treatment is all carried out to yarn after warping, Yarn filoplume is attached, stretched, increased wear-resisting while carrying out enhancing guarantor to yarn Property.But warping generally uses piece yarn starching, and it is inter-adhesive, it is necessary to wet, dry leasing, yarn leasing that piece yarn starching may result in yarn When mutually tear destruction yarn body surface starch adhesive film, produce secondary filoplume.As can be seen here, Yarn filoplume is eliminated, increases 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 for generally using has two kinds, one kind It is that common ring spinning process is optimized using conventional method, the method can only to a certain extent reduce Yarn filoplume, action effect It is 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.It is new at present It is Advance of Compact Spinning Technology that type ring spinning technology is represented, such as Department of Intellectual Property of the U.S. invention disclosed patent of 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 the U.S. invention disclosed of on June 13rd, 2000 is special Sharp " Device for condensing a drafted fiber strand ", the patent No. 6073314；Department of Intellectual Property of the U.S. The invention disclosed patent of on June 13rd, 2000 " Device for condensing a drafted fiber strand ", specially Profit number 6073314；Department of Intellectual Property of U.S. invention disclosed patent " the Arrangement for of on July 4th, 2000 Condensing a drafted fiber strand ", the patent No. 6082089；Department of Intellectual Property of the U.S. public affairs of on January 9th, 2001 The patent of invention " Transport belt for transporting a fiber strand to be condensed " opened, Patent No. US 6170126B1；Department of Intellectual Property of U.S. invention disclosed patent " the Arrangement and of on July 24th, 2001 method for condensing a drafted fiber strand and method for making yarn Thereform ", the patent No. US 6263656B1；Department of Intellectual Property of the U.S. invention disclosed patent on the 14th of August in 2001 " Apparatus for condensing a drafted strand ", patent No. US 6272834B1；Department of Intellectual Property of the U.S. The invention disclosed patent of on May 29th, 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, compact spinning trigonum Fiber strip, strengthens controlling fiber strip edge fibers, effectively reduces spinning process fiber head end and exposes, and reduces yarn hair Plumage；But compact spinning eliminates spinning triangular zone, the inside and outside transfer of yarn body internal fiber is inadequate, and cohesive force is not enough, and outer layer still has filoplume to reveal Go out, filoplume still increases severely after yarn body undergoes friction；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.

At present the special reduction filoplume device that uses be using jet-impingement form, installed in front roller and twizzle it Between, make established filoplume patch volt in yam surface, such as Department of Intellectual Property of the U.S. public affairs of on April 10th, 1979 using the revolution of air-flow The patent of invention " method and apparatus yarn treatment " opened, the patent No. 41481779, U.S.'s intellectual property Office's August in 1989 invention disclosed patent " method and apparatus for modifying spun textile on the 22nd Yarn ", the patent No. 5263311.These researchs are main difference is that because the difference of airflow injection device causes yam surface fine Dimension Impact direction is different, so as to produce different winding effects and cause the difference of Yarn filoplume eradicating efficacy.But due to this A little devices can be only installed at behind twist triangle zone (because the fiber in twist triangle zone is basic into staple in bulk shape, the air-flow of injection Fiber movement can be caused chaotic and breaked end), its air-flow brushes object for yarn and yam surface filoplume, brushes being bullied for two objects Flow rotation effect is different, realizes for filoplume staying in yam surface in the form of simple patch volt and lax winding；In later process (such as Winder) in processing, parts rub the fiber of withdrawing yarn surface structure, and the filoplume of lax docile and winding is revealed again, The real effect for eliminating filoplume is not reached.

For winding procedure high-speed friction, yam surface structural damage, filoplume is caused largely to increase, strength declines, it is desirable to The problems such as supporting sizing operation, increase starching difficulty and sizing cost, filoplume flattening device is set in winding procedure, suppresses filoplume Generation, to later process produce and improve end product quality tool be of great significance.The reduction studied at present The method of resultant yarn filoplume is concentrated mainly on reduction Winding yarn filoplume device；Although Patents documents have a lot, use General principle is identical, i.e., being used on bobbin-winding machine in yarn carries out backtwisting-twisting mode to advancing yarn, makes yam surface Filoplume reaches the purpose for reducing filoplume wound on yam surface.Representational patent document has：European patent number is EP 0 866 014 A2, publication date 1998 year 09 month 23 days, invention and created name is Auto Winder, and this application complicated legal case uses winding process The mechanism of navel is turned round in flow, makes wandering fibre along the sth. made by twisting of yarn to coming with patch volt to yarn, to reduce yarn hair Plumage；The B1 of U.S. Patent No. US 6 374 588, publication date 2002 year 04 month 23 days, invention and created name is Hairiness Controlling device and winder, this application complicated legal case is using the machinery work that navel is turned round in winding process flow With, make 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, publication date on October 17th, 2001, 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 is analyzed from principle, only according to the looping effect of air-flow, its covered effect is bad；Europe The A2 of patent No. EP 1 013 803, publication date 2000 year 06 month 28 days, invention and created name is Hairiness Suppressing device for automatic winder, this application complicated legal case equally uses air vortex flow tube, by air-flow Yarn is rotated, when the yarn of rotation is by control panel (regulating plate), fiber is wrapped over yarn, to subtract Few filoplume；China Patent No. be ZL 99127507.1, publication date 2000 year 07 month 05 day, invention and created name is automatic winding The filoplume flattening device of machine, this application complicated legal case equally uses air vortex flow tube, and yarn is rotated by air-flow, but the patent is logical Cross and install controller additional at device two ends, to ensure that yarn produces false twist effect along own axes revolution, improve and reduce Yarn filoplume Efficiency.In addition, China Patent No. is ZL 200710052991.8, publication date 2008 year 01 month 23 days, innovation and creation name Referred to as a kind of method for reducing resultant yarn filoplume, this application complicated legal case provides a kind of by the way of false twisting flatiron, to winder and knitting The yarn of process carries out online attaching and is involved in yarn body, realizes winder or knitting process with wrap yarn filoplume, few part filoplume It is middle to suppress the mesh that Yarn filoplume increases.The method and apparatus of above-mentioned reduction yam surface filoplume, have in common that Yarn filoplume Lodged by air-flow or mechanical type, be wrapped over again yarn it is dry on；But during whole filoplume flattening, again looping, all do not have Actively effectively gripping effect, again filoplume flattening, looping are loosely organized, and yarn top layer densification degree does not improve, and reduces Filoplume undergo friction and be easy to rebound again；When filoplume is wound into yarn body simultaneously, because of fibril aggregation, the yarn reduced after filoplume is thick The yarn defect such as section, cotton knot is significantly increased.

Above-mentioned as can be seen here that the yarn such as winder, warping, knitting is controlled using the Yarn filoplume of process, existing method is common Put and be：In the case where non-positive grips filoplume head end, false twisting is carried out to yarn or air-flow brushes looping, yarn table will be stretched out Most filoplumes in face are wound in loosely form, docile cannot be formed between yarn face, filoplume fiber and yarn body Fine and close structural nexus, only visually realizes that filoplume is reduced；For in the form of backtwisting-twisting, filoplume process is attached In, the yarn part twist is subject to dynamic transfer and redistribution, the weaker position of the twist occurs, is easily stretched by yarn tension and deteriorated The yarn body trunk uniformity.More it is essential that in later process, as yarn is rubbed by parts, these lax winding, patches The fiber taken in yam surface is easy to stretch out yam surface formation filoplume again, processing and final product to yarn later process The quality (especially knitting product quality) of product improves without essence.
