Description

A selvedge of a woven fabric that looks and behaves like a knitted fabric

technical field

The utility model relates to a fabric and a production method thereof, in particular to a selvedge of a woven fabric with the appearance and performance as knitted.

Background technique

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 number of warp yarns passed by the loops is at least 6, and the elastic yarns form alternately arranged lower and upper portions with respect to the warp yarns in a tighter weave than hard yarns.

The fabric disclosed in the patent application number 201180010682.9 has no selvage, and the weaving method of the selvedge is not disclosed. However, the selvedge is an important part of the fabric, and the selvedge design includes the selvedge, the overlock and the waste edge. The basic function of the selvedge is to protect the fabric body, fix the warp yarns on the side of the fabric to prevent loosening and slipping, increase the resistance of the fabric to external forces, and ensure that the processing requirements of the subsequent processes such as weaving, finishing, and garment making are met; the function of the seam is to use The overlock warp yarn interweaves the free ends of the weft yarns of the fabric firmly to form a stable edge structure; the function of the waste edge is to hold the weft yarn through the interweaving of the waste edge yarn and the weft yarn, and maintain a certain tension on the weft yarn to prevent weft shrinkage.

In particular, the fabric structure characteristic disclosed in the patent application number 201180010682.9 is that the weft yarn is woven according to a certain rule by at least one elastic yarn and at least one hard yarn, and the weft float length of the reverse side of the woven fabric is at least 6 , which means that there are no more warp yarns interlaced with the weft yarns of the reverse weave to form a better fixing effect, and the use of this weave and yarn count combination is prone to weft shrinkage and inconsistent loops on the bottom surface. That is to say that when weaving the fabric disclosed by the patent of 201180010682.9, if there is no selvedge, weaving or production work is difficult to carry out, especially mass production is just impossible, and it can only be used for small sample experiments.

In order to form a fabric with a hand feel similar to that disclosed in the patent application number 201180010682.9, reorganization is usually used, that is, the law of ups and downs of two adjacent weft yarns passing through the warp yarns is the same, so that the cloth body after the first weft has no other warp yarns with it. Interlacing, at this time mainly rely on selvedge, waste edge, lock edge to fix this weft yarn.

It has been explained above that selvedge, waste edge and overlock have more important effects on the fabric disclosed in the patent application number 201180010682.9 than general woven fabrics.

The fabric structure characteristic disclosed in the patent application number 201180010682.9 is that the weft yarn is woven by at least one elastic yarn and at least one hard yarn according to certain rules. More warp yarns and the weft yarns of the reverse weave are interlaced to form a better fixing effect, but weaving is prone to weft shrinkage when weaving with this weave structure and yarn count combination, and inconsistent weft yarn tension causes different lengths of bottom piles; in addition, due to loose structure, In order to keep the cloth surface smooth and the width stable and consistent, a certain tension will be applied after finishing. If the selvedge of conventional fabrics is not easy to form a stable selvage, the cloth body is not uniformly stressed, and it is easy to cause color difference in the middle edge and edge centering. The weight deviation per square meter; the weft yarn of this woven fabric contains elastic yarn, which causes the front and back sides to shrink inconsistently, and it is easy to form curling. Excessive curling will cause serious creases on the fabric surface. At the same time, in order to form a reverse texture similar to that of knitted fabrics, reorganization is usually used, that is, two adjacent weft yarns pass through the warp yarns with the same ups and downs, so that after the first weft is drawn, there are no other warp yarns interlaced with it. At this time, it mainly depends on the fabric. The selvedge secures this weft yarn. To sum up, according to the selvage of conventional fabrics, there will be more quality problems, resulting in low production efficiency and unable to realize large-scale production.

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 , Affect the practicability and aesthetics of the cloth surface. In response to 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.

For the production method of the selvedge of woven fabrics such as the above-mentioned appearance and performance, when the number of heald frames configured on the loom is greater than 2 pages or more of the cloth body weave cycle, the selvage hedging can adopt 1.1.2.2 For the method of threading, the width of the selvedge is set to 1.3cm~3cm. The number of reeds is one or more than the cloth body, and the weave structure is re-flattened or changed.

As in the above-mentioned method for producing selvedges of woven fabrics such as knitted fabrics in terms of appearance and performance, when the number of heald frames configured on the loom is greater than 1 page of cloth body weave cycles or equal to the number of cloth body weave cycles, it cannot weave independent For selvage, it is necessary to use the heald frame of the cloth body to weave the selvage. This method includes that the ground weave can adopt the threading method and the heald of the selvage weave is preferentially used in the opposite or different way to the cloth body. Symmetrical textures form cross resistance. Using this method can not only achieve the effect of saving healds, but also facilitate the clear opening, which is convenient for weaving and can effectively reduce weft shrinkage.

As a further improvement of the technical solution of the utility model, at least 4 yarns per reed are used for the ground weave, and at least 5 yarns per reed are used for the selvedge weave.

The selvage of the utility model can protect the fabric body, keep the cloth surface smooth and the width is stable and consistent, after finishing, a certain tension will be applied, and the selvage of the fabric can easily form a stable selvage, so that the warp yarn on the side of the fabric is not easy Loose and slippery, increase the resistance of the fabric to external forces; it can make the cloth body evenly stressed, and it is not easy to form a color difference in the middle edge and a small deviation per square meter in the middle edge, ensuring that the processing requirements of the subsequent processes such as weaving, finishing, and garment making are met.
