Abstract
A kind of device of multifilament textile of handing over comprises fuselage (1,2), and this fuselage has the path of a continuous yarn path as multifilament textile (M).This yarn path determines to have at least a nozzle (9) side direction to terminate in this yarn path by first wall (7) and second wall (8) in first wall, second wall is positioned at the opposite of nozzle (9) outlet.At least one is along the buckling of yarn path in two walls.Therefore, the distance between two walls increases towards the two ends, yarn path gradually from the minimum of a value in nozzle (9) exit.This moving gaseouse medium speed that causes flowing into and flow to the two ends, yarn path from nozzle (9) outlet reduces gradually.
Description
The present invention relates to a kind of device of intermingling yarns.
The objective of the invention is to, this device is designed to such structure, with the device of routine by comparison, it can make multifilament textile produce more uniform entwining, especially front and back link to each other entwine a little between distance more even, and the higher density of entwining is arranged, and this density is entwined to count with every meter and is measured.In addition, can also be as requested in every meter, form many well-regulated entwining by force a little, perhaps in every meter, form and manyly entwine a little a little less than well-regulated.
Reached this purpose according to device of the present invention, by making a bending in symmetrical plane in two walls at least, thereby the distance between two walls measuring in this symmetrical plane increases to the two ends of yarn path gradually from the minimum of a value at the nozzle mouth.
In the interlacing apparatus of routine, the energy of fluid, (in most applications is air, send into and the discharge of warp yarn passage by nozzle), jet expanded yarn there is adverse influence, for example its can a little reopen weak entwining, thereby make and entwine irregularly, also reduce the density entwine simultaneously.Also have by the line tension in the yarn line segment of nozzle mouth, because fluid is to the flowing of two ends, yarn path, and extra increasing, this makes the difficulty more of entwining.
In device of the present invention, if the width of yarn path keeps constant substantially in the mode of optimizing, then increase by the terminal direction of the distance between wall to the yarn path, make the cross section of yarn path towards the corresponding increase of terminal.Interlacing apparatus is usually designed to like this, makes near the pressure ratio device of nozzle mouth atmospheric pressure on every side only higher slightly.The energy ladder that only in this way just can effectively utilize in the device becomes.Therefore in device of the present invention, because the cross section of yarn path increases towards the terminal direction, fall so in fact no longer have pressure, according to the Bernoulli continuity equation, the speed of discharging medium must reduce; This is because the cross section of yarn path increases gradually towards the terminal direction, thereby air-flow can not break away from the wall of yarn path.At energy theorem E=1/2 mv
2In, square being directly proportional of speed with energy.When the speed that flows out from the yarn path when fluid reduces, for example drop to half, so You Hai energy just drops to 1/4th.
As mentioned above, at the yarn path width that measures perpendicular to symmetrical plane, be preferably in the whole length of yarn path and remain unchanged substantially.In order to improve the quality of entwining,, should keep optimum yarn path width especially for the high density of entwining.The air-flow that is blown into is divided into two approximately equalised fibre bundles in the moment that impacts second wall with fibre bundle, and this two bundle fiber only with a certain distance from the place of nozzle, just can merge into the knot of entwining that forms in nozzle mouth both sides again.One can the yarn path of degree of broadening towards each terminal in, the further expansion of two bundle fibers can make the formation of the knot of entwining further from nozzle.This will reduce the density of entwining, and increases the distance between entwining a little.
