and performing a compact spinning section color yarn machine process and a winding process on the first rough yarn and the second rough yarn after transformation to obtain the slubby yarn.
In the production method of the slub yarn, the first fiber is selected from one or more of natural fiber, regenerated cellulose fiber, synthetic fiber and the like. The first fiber is selected from natural fiber, preferably cotton fiber, the cotton fiber is porous substance, and many hydrophilic genes (-OH) exist on cellulose macromolecules, so that the hygroscopicity is better.
In the production method of the slub yarn, the second fiber is selected from one or more of natural fiber, regenerated cellulose fiber and synthetic fiber. The second fibers are selected from synthetic fibers, preferably from polyester, more preferably from moisture wicking polyester.
The first roving and the second roving are selected from any color known to those skilled in the art.
The fiber raw materials and/or the color of first roving and second roving are different, and the fiber raw materials and the color of first roving and second roving can not be the same simultaneously, and are specific:
when the first and second fibers are different in composition, the first and second rovings are different in color;
when the composition of the first fiber and the second fiber is the same, the first roving and the second roving are different in color;
when the first roving and the second roving are the same in color, the first fiber for preparing the first roving is different from the second fiber for preparing the second roving, for example, when the slub yarn is made of a white blank yarn, the composition of the first roving is different from that of the second roving.
According to the production method of the slub yarn, the first roving is processed by a compact spinning segment color yarn machine to form the base yarn of the slub yarn, a plurality of slubs are arranged on the base yarn, the slub node length is 30mm-50mm, and the pitch length is 50 mm-1000 mm. The slub pitch length refers to a linear distance from the starting end of one slub on the base yarn to the tail end of the slub along the length direction of the base yarn, and the pitch refers to a distance between two slubs on the base yarn, specifically to a linear distance from the tail end of one slub to the starting end of another slub. The part outside the slub is called a non-slub part of the base yarn, and the slub of the base yarn is called a slub of the base yarn.
In the method for producing the slub yarn, the second roving is processed by a compact spinning segment color yarn machine to form the additional slub yarn of the slub yarn, and the additional slub yarn is superposed on each slub part of the base yarn (shown in figure 1b) or is independently knotted on the non-slub part of the base yarn (shown in figure 1 c).
In the production method of the slub yarn provided by the invention, in a section of slub, the additional slub yarn superposed on the slub part of the base yarn accounts for 10-100 wt% of the slub part of the slub base yarn.
In the production method of the slub yarn provided by the invention, the slub multiplying power of the base yarn is 1-2 times, and the composite slub multiplying power of the slub yarn is less than or equal to 3 times. The multiplying power refers to the weight ratio of slubs to base yarns or slubs.
The yarn produced by the method for producing slub yarn provided by the invention is white blank yarn or colored spun yarn.
In the production method of the bunchy yarn provided by the invention, the improved compact spinning segment color yarn machine process comprises one or more of the following characteristics:

the drafting multiple of the spinning process is 15-35 times;
the twist of the spinning process is 283-860T/m;
the spindle speed of the spinning frame is 9000-14000 r/min.

The compact spinning frame can realize the complementary motion of the first yarn and the second yarn of the two pieces of thick yarns of the section color yarn under the control of the stepped leather collar.
When the spinning frame of the equipment for tightly spinning the section-color yarns is adopted, the first roving is the main yarn and is only controlled by the middle roller, the second roving is the auxiliary yarn and is only controlled by the rear roller, the respective movement between the two rovings is regulated and controlled by controlling the rotation and the rotating speed of the two servo motors, the respective movement of the first roving and the second roving of the two rovings of the slub yarns under the control of the stepped leather collar is realized, because the first roving and the second roving are respectively controlled by the middle roller and comprise the coaxial stepped rough leather collar section and the fine leather collar section, the movement is relatively independent, the second roving generates slipping at the fine leather collar section, the second roving is not controlled by the middle roller and is only controlled by the rear roller, and therefore, the uniformity and the quality stability of slub of the slub yarns are controlled.

For example, when a first roving needs to form a 1.3-time bamboo joint, the motor controlling the middle roller accelerates, the middle roller accelerates 1.3 times, the first roving generates a 1.3-time bamboo joint, but the rear roller also accelerates, but the acceleration is 2 times, so that the second roving controlled by the rear roller is controlled by the stepped apron to slide, and the first roving and the second roving move independently; thus, the 1.3 times base yarn slub of the first roving and the 2 times additional slub of the second roving form a 2.3 times composite slub together at the front jaw.

Figure 8 is a photographic representation of fabrics woven from yarns obtained in example 7 (right panel) of the present invention and comparative example 1 (left panel).
The bunchy yarn produced by the embodiments 1-8 has stable process and less defective yarn. The fabric woven by the slub yarn has good air permeability and unique moisture absorption and sweat releasing functions, for example, moisture absorption and sweat releasing terylene at the slub part of the fabric woven by the yarn in the embodiment 7 directly contacts with skin, and the moisture absorption and sweat releasing terylene increases the capillary effect and the specific surface area of the fiber by changing the cross section shape of the fiber. This polyester fiber utilizes the surperficial micro groove, with skin top layer moisture through the wicking, the diffusion, the conduction effect, carry hydrophilic cotton fiber fast and absorb water, thereby keep the dry and comfortable sense of human skin, especially when the human body is perspired in a large number, the sweat is absorbed by hydrophilic cotton, the clothes is very moist, but the human bamboo joint part of contact is the dacron composition, it is very low because of the moisture regain of dacron, embody dry and comfortable effect, therefore this human can be very comfortable, simultaneously because the convex-concave structure of bamboo joint surface fabric, accelerate the flow of air, the effect of fast drying again.
The production method can lead the bunchy yarn to show the characteristics of a node upper node or an additional node; combining the color change of the colored spun yarns, and creating colored additional slub yarns, namely slub parts have different structures and colors; and the characteristics of the fiber are combined, the difference of the structures and the components of the slub part and the base yarn part is created, so that the slub yarn is finally prepared.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
