Description
Technical field
The utility model relates to a kind of negative pressure and guides the submissive bright and clean spinning apparatus of catching type, belongs to technical field of textile processing.
Technical background
Filoplume is one of important indicator 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, particularly high speed shuttleless loom today of generally applying, reduces Yarn filoplume tool and is of great significance.
Yarn filoplume results from the spun yarn manufacturing procedure of ring spinning.The spinning process key issue of common ring ingot spinning is: fiber strip pressure holding is flat belt-like by front roller nip, under the effect of twisting twisting resistance, there is inside and outside transfer in the fiber in flat belt-like fiber strip, when fiber a part has entered yarn body by inside and outside transfer, after now this fiber exposes the head portion disengaging front roller nip gripping effect of yarn body, cannot again enter or looping on yarn body trunk, so formed filoplume; When fiber is positioned at the most edge of flat belt-like fiber strip, attachment obvolvent active force between fiber and twisting yarn main body is weak, fiber just goes out front roller nip, very easily be subject to the negative-pressure air-suction swabbing action of flute pipe and change direction, depart from the sliver main body of twisting, after now fiber departs from front roller nip gripping effect completely, directly siphoned away by the negative pressure of flute pipe, form the fibre that falls, reduce fiber utilization rate and ring spinning quality.
For the problem of ring spindle yarn operation filoplume and yarn quality difference, scholar both domestic and external does excessive quantifier elimination.The approach of usual employing has two kinds, and one adopts 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 adopts Advanced Spinning Technologies or special elimination filoplume device to eliminate filoplume, significantly improves ring spinning quality.Novel ring ingot spinning technology or special elimination filoplume device are the focuses of current ring spinning technical research.Current Novel ring ingot spinning technology representative is 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, assemble flat belt-like fiber strip to eliminate spinning triangular zone, increase edge fibers and twisting yarn intersubjective attachment obvolvent active force, strengthen controlling fiber strip edge fibers, effective reduction spinning process fiber head end exposes and escapes, reduce Yarn filoplume and fiber loss, suppress flyings to produce.But compact spinning eliminates spinning triangular zone, not, the too straight densification of internal fiber arrangement, causes that yarn rigidity is too large, pliability severe exacerbation to the inside and outside transfer of yarn body internal fiber; Especially, by the Advance of Compact Spinning Technology of airflow concentration, need additionally to install negative-pressure ward equipment additional, energy consumption significantly increases, cause the installation of compact spinning process, operation and maintenance cost high, become lordliness spinning, run counter to the new principle that energy-saving and cost-reducing, low-carbon (LC) is produced.
The special reduction filoplume device of current use adopts jet-impingement form, be arranged between front roller and twizzle, the extra effect applying revolution air-flow is utilized 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 patent essential difference are because the difference of airflow injection device causes yam surface fiber Impact direction different, thus produce different winding effects and cause the difference of Yarn filoplume eradicating efficacy.But due to these devices can only be arranged on twist triangle zone after (because the fiber in twist triangle zone becomes bulk fibre shape substantially, the air-flow sprayed can cause fiber movement chaotic and break end), it is yarn and yam surface filoplume that its air-flow brushes object, the flow rotation effect of being bullied of brushing two objects is different, filoplume is realized to stay yam surface with the form of simply pasting volt and lax winding, cause in later process (as winder) processing, the fiber of parts friction withdrawing yarn surface structure, the filoplume of lax docile and winding reveals again, do not reach the real effect eliminating filoplume, and these special reduction filoplume devices cannot solve flat belt-like edge fibers and are easy to escape and form the key issue of fall fine and flyings.
China Intellectual Property Office's on 07 11st, 2007 invention disclosed patents " a kind of flatiron spinning method improving yarn property ", the patent No. 200610166509.9; Department of Intellectual Property of the U.S. discloses patent of invention " Method and apparatus for producing high quality yarn on a ring-spinning machine ", patent publication No. 7552580B2 on June 30th, 2009.These two application complicated legal cases together provide a kind of flatiron spinning method that can heat to improve to fiber in spinning triangular zone yarn quality.But ironing apparatus involved by the method only limits to, and reduction fiber modulus is easily reversed to improve fiber, flexible performance, improves resultant yarn fineness, flat belt-like edge fibers cannot be solved and be easy to the key issue that escape forms fall fine and flyings.Equally, ironing apparatus still brings extra energy consumption issues, and to some thermo-responsive poor fibers (as wool fibre) carry out flatiron spinning action effect poor, spinning yarn quality can not get improvement.
