A kind of have dynamic solid and gather the ring spinning of Fushun function and draw yarn rubber roll

Technical field

The present invention relates to a kind of there is dynamic solid to gather the ring spinning of Fushun function and draw yarn rubber roll, belong to technical field of textile processing.

Background technology

Filoplume is one of important indicator weighing yarn qualities.Yarn filoplume not only affect woven, knitting etc. after spin the production efficiency of operation, and affect the presentation quality of final products, particularly bright and clean soft and smooth contour quality textiles produced, reduce Yarn filoplume tool and be of great significance.Because filoplume results from spinning process, so reducing fuzzy yarn is to reduce basis and the key of filoplume.In tradition ring throstle spinning process, through the sliver of drawing-off with one fixed width and after leaving front roller in a free state, it is processed to yarn the most immediately, therefore the formation region at yarn can form a spinning triangular zone, and the fiber loose due to spinning triangular zone can not well control, and a lot of fiber head ends causing yarn peripheral expose sliver surface, form Yarn filoplume, have a strong impact on resultant yarn exterior quality, reduce fiber utilization rate, deteriorate spun yarn strength and extension property.

Producing, for ring spindle yarn operation, the technical problem that filoplume is too much, scholar both domestic and external does excessive quantifier elimination.The approach generally used has two kinds, and one is to use 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 use Advanced Spinning Technologies or special elimination filoplume device to eliminate filoplume, and ring spun yarn line filoplume can be greatly lowered.Novel ring ingot spinning technology or special elimination filoplume device are the focuses of current ring spinning technical research.Novel ring ingot spinning technology represents at present is Advance of Compact Spinning Technology, such as Department of Intellectual Property of U.S. December in 1984 invention disclosed patent " Device for stretching, condensing and transporting a rove on the 18th Of fibers during a spinning operation ", patent No. US 4488397;Department of Intellectual Property of U.S. invention disclosed patent " Device on June 13rd, 2000 Condensing a drafted fiber strand ", the patent No. 6073314; Department of Intellectual Property of U.S. invention disclosed patent " Arrangement on July 4th, 2000 Condensing a drafted fiber strand ", the patent No. 6082089; Department of Intellectual Property of U.S. invention disclosed patent " Transport belt in 9 days January calendar year 2001 For transporting a fiber strand to be condensed ", patent No. US 6170126B1;Department of Intellectual Property of U.S. invention disclosed patent " Arrangement and in 24 days July calendar year 2001 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 " Apparatus in 14 days Augusts calendar year 2001 Condensing a drafted strand ", patent No. US 6272834B1;Department of Intellectual Property of U.S. invention disclosed patent " Condensing zone in 29 days Mays calendar year 2001 For a spinning machine ", patent No. US 6237317B1；China Intellectual Property Office's invention disclosed patent on April 28th, 2004 " compact spinning apparatus of ring throstle ", patent publication No. CN2613493；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 by the way of negative-pressure air-suction, strengthens controlling fiber strip edge fibers, effectively reduces spinning process fiber head end and expose, reduce Yarn filoplume, improve spinning yarn quality.But negative-pressure air-suction centralization type compact spinning process, consuming a large amount of negative-pressure gas, energy consumption is big, and operating cost is high；Negative pressure collecting grid ring easily blocks, and maintenance cost is high；Adding negative pressure collecting equipment complicated, installation cost is high, and negative-pressure type compact spinning process has become lordliness Yarn spinning method.
