Problems solved by technology

In summary, according to the selvage of conventional fabrics, there will be more quality problems, resulting in low production efficiency and unable to achieve large-scale production
[0008] The denim woven fabric of this knit-like fabric has a loose overall structure, at least one elastic yarn is used for the weft yarn, the shrinkage rate of the down machine will be different from that of the conventional variety, and the reverse side has loops, and there will be a color difference in the edge during finishing. , The difference in the square meter weight between the sides and the medium density of the side is prone to creases on the cloth surface, messy loops, and advances at the same time. The weft density of this type of variety is generally high, and it is difficult to shrink the weft density in place when compared with conventional varieties. , causing warp shrinkage to exceed the standard; in addition, most of these varieties use elastic weft yarns, which are more difficult to shrink to the requirements than conventional varieties when controlling weft shrinkage, and the cloth surface is prone to unevenness, and it is easy to cause flowering and chicken scratches , affecting the practicability and aesthetics of the cloth surface, in view of this series of problems, a series of adjustments are made in the final stage to ensure the smooth production and the quality of the variety

Embodiment 1

[0031] The appearance and performance of this embodiment is like the selvedge of a woven fabric of a knitted fabric, including warp and weft. The warp and weft are interwoven with light and heavy flat or variable light and heavy flat weaves to form a selvedge, and the width of the selvage is set to 1.3cm~ 3cm, the total tightness of the selvedge is 20%~35% larger than the cloth body, the warp yarn is made of pure cotton yarn or blended cotton yarn or chemical fiber filament, and the weft yarn is made of at least one hard yarn and at least one Elastic yarns are alternately arranged according to a predetermined arrangement, wherein the special number of pure cotton yarn or blended cotton yarn is 14tex~59tex, and the denier number of chemical fiber filament is 75D~450D. The elastic yarn can be high elastic yarn or Filament core-spun yarn, the denier number is 100D~600D; the elastic yarn can also use cotton-spandex core-spun yarn or blended cotton-type spandex core-spun yarn, the d...

Embodiment 2

[0033] This embodiment is a method for producing a selvedge of a woven fabric with the appearance and performance as described in Embodiment 1. The method includes: when the number of heald frames configured by the loom is greater than 2 pages of cloth body weave cycles and When the above is above, the selvedge can be woven separately; that is, when the loom is configured with 12 heald frames or more, the weaving cycle is 10, the selvedge width is set to 1.3cm~3cm, the drawing-in method 1.1.2.2 is adopted, and the selvage is threaded The number of reed penetrations is at least 5 yarns per reed (at least 4 yarns per reed is used for the ground weave), preferably 5 yarns per reed, that is, the number of reeds at the edge of the cloth is one or more than the cloth body, and the weave adopts 4 / 4 warps or 5 / 5 warps, preferably 5 / 5 warps; when the loom is equipped with 14 pages of heald frames or more, the weaving cycle is 12, the selvedge width is set to 1.3cm~3cm, and the heald A...

Embodiment 3

[0035] This embodiment is also a method for producing a selvedge of a woven fabric having the appearance and performance as a knitted fabric as described in Embodiment 1, the method comprising:

[0036] When the number of heald frames configured on the loom is greater than 1 page of cloth body weave cycle or equal to the number of cloth body weave cycles, the independent selvage cannot be woven, and the heald frames of the cloth body need to be used to weave the selvage edge. This method includes ground weave The threading method can be adopted, and the threading method of the selvage weave can be preferentially used in the opposite or different threading method to the ground weave to form a pattern symmetrical with the cloth body to form a cross resistance. This method can not only achieve the effect of saving healds, but also It can help clear opening, facilitate weaving and effectively reduce weft shrinkage.

[0037] Such as figure 1 , the figure is the weave cycle diagram...

Abstract

The invention discloses a selvage of a woven fabric with the impression and the performance like a knitted fabric and a production method of the selvage. The selvage is prepared from warps and wefts, wherein the selvage is produced by interweaving the warps and the wefts in a light, heavy or flat manner or a varied light, heavy or flat manner, the total tightness of the selvage is larger than that of a fabric body by 20-35 percent, the warps adopt cotton yarns or synthetic filaments, the wefts adopt at least one hard yarn or at least one elastic yarn which is alternately arranged according to the preset arrangement, the count of the cotton yarns is 14-15tex, and the denier of the synthetic filaments is 75-450D. The selvage is capable of preventing the warps from loosening and slipping, improving the external force resistance of a fabric and ensuring to achieve the processing requirements for latter procedures including weaving, finishing and clothing.

Description

technical field [0001] The present invention relates to a fabric and its production method, in particular, to a selvedge of a woven fabric which has the look and feel and performance of a knitted fabric and its production method. Background technique [0002] The application number is 201180010682.9, and the patent name is woven fabric with appearance and performance like knitted fabric and its manufacturing method, which discloses a fabric with weft yarns, which includes hard yarns and elastic yarns in a predetermined arrangement, and the predetermined arrangement makes at least one one hard yarn is alternately arranged with at least one elastic yarn, said elastic yarn has a shrinkage greater than that of said hard yarn; A yarn is formed and defines a loop when passing along the back side of the warp yarn, and the upper portion is formed and defines a connecting portion when the hard yarn is passed along the front side of the warp yarn, wherein for each hard yarn , the num...
