Abstract
The present invention discloses a kind of processing method for conjugate yarn. The first fiber rove is fed in from back roller group and the difference of rotation velocity between the front and back roller groups enables the first fiber rove to be drawn into the first fiber tassel ribbon; the second fiber rove is fed in from the middle roller group and the difference of rotation velocity between the front and the middle roller groups enables the second fiber rove to be drawn into the second fiber tassel ribbon. The ring twisting enables the first fiber tassel ribbon exported from the front roller group and the second fiber tassel ribbon to be amalgamated and intertwined into a conjugate yarn. A roller drawing mechanism consists of front roller group, middle roller group and back roller group while the middle roller group consists of middle roller and middle leather roller corresponding to the middle roller; both the middle leather roller and the middle roller have at least one upward ring groove for each. The first fiber rove is placed in one flank of the ring groove. The first fiber rove and the second fiber rove can be different in fiber length one from the other. Adjusting the rotation velocity of the back roller group or the middle roller group can spin changeable conjugate yarns.
Description
Technical field
The present invention relates to a kind of preparation method and roller drafting mechanism of combination yarn.
Background technology
In the prior art, roller drafting mechanism comprises the front roller group, the middle roller group, the rear roller group, described middle roller group comprises middle roller, the medium rubber roller of relative pressure with described middle roller, during combination yarn that production is made up of two kinds of yarns, usually two kinds of rove are fed the rear roller group simultaneously, by the middle roller group simultaneously with described two kinds of rove preliminary drafts, again two kinds of rove are fed described front roller group simultaneously subsequently, the velocity of rotation of described front roller group is faster than described middle roller group, this moment, described two kinds of rove all were drawn as the yarn of flat narrow shape, by described front roller group output, the twisting of ring ingot makes two kinds of yarns merge mutually, after the merging, described two kinds of yarns twine the formation combination yarn mutually.The processing method of this combination yarn and equipment make that two kinds of yarns must be with long fiber, and because the drawing-off ratio of two kinds of yarns of output is the same, therefore the line weight of spun combination yarn is even, does not have variation, thereby has influenced the development of combination yarn and even dress ornament.
