Two groups of fibers are fed into a drawing mechanism of a spinning frame in parallel through being kept with a certain interval between each other; the fibers in each group comprise short fiber fringings, filaments and at least one of the short fiber fringings and the filaments; the short fiber fringings in the fibers in each group are fed from a back roller and fed to a front roller via a middle roller; filaments corresponds to short fiber fringings in the same group, the filaments in the fibers in the same group are fed from the backside of the front roller; the two groups of fibers fed in parallel are output in the same drawing jaw line position under the control of two groups of front rollers; the speeds of the front rollers in the two groups are different from each other; the lengths of the two groups of fibers output within a unit time are different from each other; and the method of the front rollers for controlling difference between output speeds of the two groups of fibers has a continuous form or a sectional alternating form.
Description
Technical field
The invention belongs to spinning shaping manufacture field, relate to a kind of many components composite spinning drafter.
Background technology
The principle of Siro-spun yarn is: on ring throstle, corresponding to same ingot position, adopt two groups of rove with the rear roller feeding of certain spacing from drafter, two groups of rove fiber strips are in parastate by the while drawing-off in the drawing-off zone, two bundle fiber yarns in the past roller nip out keep forming certain distance afterwards, these two fibre bundles are at the rotary action of ring throstle spindle, twisting polymerization resultant yarn, it is bright and clean that siro-spinning yarn has advantages of that surface fiber marshalling, filoplume reach outward appearance less.
The principle of RING SPINNING filament short-fiber composite spinning is: on ring throstle, corresponding to same ingot position, one group of rove is from the rear roller feeding of drafter, one group leader's silk is from the front roller feeding of drafter, staple fibre yarn after the drafter drawing-off is with in the past roller nip output of long filament, at the gyroscopic action of spindle, twisted becomes composite yarn, makes yarn have both some characteristics of long filament and short fiber.
In the Modern Spinning Process technology, often can adopt to change fiber combinations mode, the arrangement mode of fiber, the means such as twisted mode of fiber in the yarn, change the structure of resultant yarn, to reach change, to improve the performance purpose of fabric.
Summary of the invention
One object of the present invention is to provide a kind of many components of AB differentiation composite spinning device, changes the structure of resultant yarn, to reach change, to improve the performance purpose of fabric.
A kind of many components of AB differentiation composite spinning device, formed by drafter and long filament feed mechanism, described drafter is made of front roller, middle roller, rear roller and each roller corresponding top-roller leather roller, apron, and described long filament feed mechanism is made of thread-tension adjuster, long filament positioning guide wheel.
Preferably, drafter can adopt two kinds of structures: the front roller of mechanism is two groups and rotates the independent rollers controlled, section variable of speed and form, or the front roller of mechanism, middle roller, rear roller are two groups of roller groups of rotating independent controlled, the section variable of speed.
The front roller of described drafter is that two groups of independent rollers controlled, section variable of rotation speed form, the front roller that it is characterized in that mechanism is coaxial pair of roller, front roller is by the front roller axle, fixedly front roller, kink front roller form, fixedly front roller, kink front roller respectively by the servomotor drive, speed is controlled, section variable.
The front roller of described drafter, middle roller, rear roller are two groups of roller groups of rotating independent controlled, the section variable of speed, front roller, middle roller, the rear roller that it is characterized in that mechanism all is coaxial pair of rollers, roller group, two groups of rollers are all by the servomotor drive before, during and after having two groups corresponding to each ingot position, the front and back district draw ratio of two roller groups is by the servomotor of each roller shaft of Computerized controller control transmission or by the control of front and back roller gear ratio, the speed segmentation of two roller groups is controlled, adjustable.
The beneficial effect that the present invention realizes:
Two groups of fiber speed differences that many components of differentiation composite spinning drafter utilizes front roller to export simultaneously, and the segmentation of speed alternately changes, change the structure of yarn, can make long filament, staple fibre realize the mutual looping of multiple various combination, hold, reach the properity that changes yarn.
