Problems solved by technology

[0007] Segment colored yarn is spun by coaxial double rear rollers, and the two groups of fibers are segmented, equal in amount, and unequal in proportion to combine into yarn. When the group fibers are changed rapidly or with shorter lengths alternately, the drafting multiple of the front area of ​​the general roller drafting mechanism is larger, and the transition length of the two groups of fibers in the composite structure of A and B is longer between the lengths of the two single components. , cannot be exchanged quickly and short-distance, nor can it accurately control the distribution of the segment color on the length

Embodiment 1

[0025] Such as figure 1 and figure 2 As shown, the present invention is a method for segmented color spinning in the front section of a spinning frame. The fiber strips of groups A and B are respectively fed from the rear roller through the yarn guide bar (11) and the double-hole bell mouth (12). The back fixed roller (22) and the back looper roller (23) on the roller shaft (21) are clamped respectively, and through the double-channel yarn guide (13), the corresponding middle fixed roller ( 42) and the middle looper roller (43), which are elastically gripped by the middle roller lower apron (421, 431) and the middle roller upper apron (521, 531) and transported forward to the front roller (6), in the front drafting area , the speeds of the middle rollers in the two groups are different, the drafting multiples of the front area of ​​the two groups of fiber strands are different, and vary with the speed of the middle rollers, the second group of fiber strands after being draft...

Embodiment 2

[0032] Such as Figure 6 As shown, a segmented color spinning yarn drafting mechanism in the front area of ​​the spinning frame can be combined with the filament feeding device. The filament tension device (101) is installed on the cradle, and the filament positioning guide wheel (102) is installed on the Above the front roller, the filament (c) passes through the filament tension device (101) and the filament positioning guide wheel (102), and is positioned and fed behind the front roller, that is, it has the function of composite processing of filament, and can produce long and short fiber composite segment color Yarn or multi-component functional yarn.

Abstract

The invention discloses a method for spinning segment color yarn by front area segmentation and a drawing mechanism. The method comprises the following steps of: drawing and feeding a group A and a group B of fiber whiskers of which the linear density tex is Ta and Tb by a rear fixed roller and a rear loose roller which are arranged on the same rear roller shaft into a rear drawing area respectively, and keeping the drawing multiples of the rear area constant and the same, wherein in a front drawing area, the two groups of fibers are different in feeding speed and drawing multiple, and variable in segmentation; outputting by a front roller, adsorbing the group A and the group B of the drawn fiber whiskers to a mesh ring which is sleeved on a negative pressure special-shaped pipe; guiding and conveying by the mesh ring; allowing the fibers to pass through a Y-shaped or V-shaped air groove on the surface of the negative pressure special-shaped pipe; gathering and combining under the air flow adsorption action at the Y-shaped or V-shaped groove; and outputting and twisting by a yarn guide rubber roller to form fine yarn of which combination of different lengths and component ratios or combination of different colors are distributed in the length direction of the yarn.

Description

technical field [0001] The invention belongs to the field of spinning and forming processing, and relates to a segmented color spinning yarn forming method in the front area of ​​a spinning frame, and a device suitable for the yarn forming method of the invention. Background technique [0002] Segment colored yarn is a yarn in which the yarn color is intermittently distributed in the longitudinal direction of the yarn. At present, the color combination and yarn structure of segment colored yarn produced by existing production technology are quite different because of their different production and processing methods. [0003] For segment-colored yarn produced by skein or single-yarn segment dyeing, the fibers in each segment of the segment-colored yarn are basically the same color, and the segment-colored yarn is dull in color and prone to heavy regularity. [0004] Segment-colored yarn produced by blending and re-dying of fibers with different coloring properties has few c...
