Description

TECHNICAL FIELD

[0001] The present application relates to the field of textiles, in particular to a weaving method of slub yarn fabric, slub yarn fabric and a weaving device thereof. BACKGROUND

[0002] In the fabric, the braid is commonly used as a kind of belt fabric, which is generally in the form of a belt or a tube, and has a wide range of applications, such as in clothing, decoration and industry. When the braid is used in clothing and decoration, not only the physical properties such as strength and tensile are required, but also the appearance and other indicators such as softness and comfort are required.

[0003] Slub yarn, as a kind of fancy yarn, refers to a yarn whose thickness changes regularly or irregularly along its length. The slub yarn is composed of a base yarn part and a slub part. Generally, the diameter of the slub part is larger than that of the base yarn part. Due to its unique style on the fabric surface, the slub yarn is widely used in clothing, home textiles, decoration and other fields.

[0004] When the slub yarn is used in woven fabric, it is usually used as weft yarn. When the slub yarn is used as warp yarn, the change in diameter of the slub yarn will cause the slub yarn to be rubbed by the heald or reed during weaving, resulting in broken warp. When the slub yarn is used as weft yarn, the diameter of the slub yarn introduced into the shed is not consistent at different positions, which can easily cause the deviation of the weaving position and the appearance of defects and the phenomenon of sparse and dense roads due to uneven weft density.

[0005] In the prior art, the insertion of weft yarn is completed by the beating-up mechanism in the loom, such as the auxiliary cooperation of the reed. The reed is generally composed of a reed beam and reed teeth, which are fixedly installed on the reed beam. Due to the characteristics of the beating-up mechanism and the creep of warp yarn, the beating-up mechanism can cause uneven weft density, especially when the loom is started, which can easily cause the appearance of sparse and dense roads, seriously affecting the quality of the fabric surface. In order to overcome this shortcoming, the elastic beating-up mechanism has been developed, that is, the reed is an elastic reed, so that the beating-up stroke of the reed can be changed, and the beating-up force remains basically constant, thereby effectively reducing the appearance of sparse and dense roads when the loom is started.

[0006] However, when using the existing elastic beating-up mechanism to insert the slub yarn, although it can partially improve the quality of the slub yarn fabric, due to the existing elastic beating-up mechanism, the change range of each reed tooth in each stroke is the same, and it cannot completely match the change of the shed caused by the thickness change of the slub weft yarn, so when weaving with slub yarn as weft yarn, the phenomenon of uneven weft density and sparse and dense road during starting will still occur. Especially when weaving belt fabric with slub yarn as weft yarn, because the warp density of belt fabric is high and the fabric width is small, the uneven weft density phenomenon is more serious, which has a great influence on the fabric quality and appearance of the belt fabric.

[0007] Therefore, how to provide a weaving device and method for slub yarn fabric to reduce the phenomenon of uneven weft density and sparse and dense road during weaving of slub yarn fabric is a technical problem to be solved by the present application. SUMMARY

[0035] Embodiment one

[0036] The present embodiment provides a weaving method of slub yarn fabric, comprising the following steps:

[0037] Step one: using slub yarn composed of cotton staple fiber as weft yarn, introducing it into the shed of the loom through the weft insertion mechanism of the loom;

[0038] Step two: after the weft yarn is beaten up by the beating-up mechanism of the loom, it is interwoven with the warp yarn composed of twisted polyester multifilament to form a slub yarn fabric, wherein the different regions of the weft yarn are movably arranged on the reed teeth units of the reed, so that the corresponding reed teeth units and the reed beam body produce a corresponding slip in the beating-up direction. And it needs to be noted that after the twisted polyester multifilament is wound, threaded and reeded, it is interwoven with the weft yarn composed of slub yarn according to the weaving rules corresponding to the preset fabric structure during weaving.

[0039] From the above content, it can be known that through the above weaving method, when the slub yarn is used as weft yarn, the different regions of the weft yarn, that is, the different thickness sections of the slub yarn, are movably arranged on the reed teeth units of the beating-up mechanism, so that the corresponding reed teeth units and the reed beam body produce a corresponding slip in the beating-up direction, thereby realizing dynamic adjustment of the beating-up stroke, and each reed teeth unit touches and makes a corresponding displacement according to the fineness change of the shed position corresponding to each part of the slub yarn during the variable-stroke beating-up process followed by the reed beam body, so that the density distribution of the weft yarn in the formed slub yarn fabric is more uniform, and the phenomenon of density change during loom start-up can be effectively eliminated, thereby making the slub yarn fabric produced by the loom of the weaving device have the characteristics of flat surface, few defects, beautiful appearance, strong three-dimensionality, and can be used to weave patterned fabrics, and is better used in clothing and decoration fields.

[0040] In order to better illustrate the structure of each weft yarn 3 of the slub yarn entering the shed in sequence under the action of the weft insertion mechanism and the corresponding warp yarn 13 after weaving, as shown in Figure 2 , the adjacent two warp yarns 12a and 12b are interwoven with the corresponding different thickness parts in the adjacent two weft yarns 3a and 3b.

Moreover, through the cooperation of the respective sliding sleeves, sliding rods and elastic components, when the reed tooth unit is adapted to slide due to touching the weft yarn, it can be ensured that the first and second sliding sleeves 5 and 8 can drive the reed tooth unit to quickly reset under the rebounding action of the respective elastic components after the beating of the weft yarn is completed, so as to facilitate the smooth beating of the weft yarn next time.

The reed beam body includes at least the first reed beam 1 and the second reed beam 2 which are parallel to each other. The first reed beam 1 is connected to the first slide bar 7, and the second reed beam 2 is connected to the second slide bar 10.
