Description

TECHNICAL FIELD The present invention relates to the technical field of warp knitting of knitted fabrics for clothing, and more particularly to warp knitted lace fabrics.

In the current clothing market, many warp-knitted lace fabrics with eyelash-like patterns are applied, and most of them are used for women's underwear, shorts, and outerwear.

There are two types of conventional eyelash lace knitted fabrics: warp direction eyelash lace knits and weft direction eyelash lace knits.

The eyelash part of a conventional warp-direction eyelash lace knitted fabric is knitted with base yarns in the warp direction and pattern yarns in the weft direction. Since the base thread and the pattern thread are different, eyelashes with the same pattern have different thicknesses and colors. Also, special weft pattern yarns must be used to control knitting and additional pattern yarn guide bars for trajectory control must be used. Since the pattern yarns in the weft direction are knitted into the ground pattern as inlay yarns without forming loops, the eyelashes knitted by the pattern yarns in the weft direction are not stretched after the subsequent cutting process and during handling. If you get it, it will be solved.

The eyelash part of the weft direction eyelash lace fabric is knitted with ground yarn. Therefore, the weaving direction of the eyelashes is the same as the weaving direction of the body portion of the knitted lace fabric. Since the weave direction of the eyelashes is the same as the weave direction of the lace body, it is not possible to weave the yarn in the head of the eyelashes to aid in cutting, instead the lace knit must be cut manually. There is Conventional knitting methods have certain limitations on knit performance and pattern design. Moreover, in the conventional knitting method, the pattern yarn of the main body is woven into the eyelashes, so the eyelashes have different thicknesses. If the cut direction of the lace knit is perpendicular to the knitting direction, it becomes impossible to knit the elastic yarn in the direction perpendicular to the eyelashes. In addition, the elasticity of the wefts of the knitted lace fabric prevents the knitted fabric from having elasticity in the warp knitting direction.

The present invention makes improvements based on the background art described above, and obtains an eyelash pattern entirely by chain stitching. A warp direction eyelash lace knit is obtained which has uniform eyelash distribution at the edges, uniform color of the material and non-unraveling properties while retaining the advantages of conventional methods.

In order to overcome the limitations in the performance and design of conventional eyelash warp lace knits, the present invention provides a warp having a cutting section for cutting waste yarns and having an eyelash-like yarn on at least one side edge of the lace knit. A knitted lace fabric is provided, the eyelash-like yarns extending outward and evenly distributed on the side edges and having exactly the same thickness and material. In addition, the knitted lace fabric can obtain extensibility in the warp direction.

According to one embodiment of the present invention, the warp-knitted lace fabric comprises, on at least one side edge, eyelash-like yarns extending outwardly of a constant length and uniformly distributed on the side edge in a consistent material. have. The yarns for forming the eyelashes are looped in the warp direction. Under the tension of the jacquard yarns and pattern yarns, the eyelashes formed on the side edges of the knitted lace fabric extend outward and connect to the waste yarn portion. After knitting, the eyelash-like yarn in the warp direction is cut along the waste yarn portion, and an evenly distributed eyelash pattern is formed on the side ends, and the base of the yarn constituting the eyelash is cut to the main body portion with a certain length. extends from

Preferably extensible elastic yarns are added during the knitting of the ground pattern so that the warp knitted lace knit has elasticity in the warp direction.

Preferably, each eyelash is woven with at least one looped ground thread to form a straight eyelash pattern after heat treatment. Preferably, the eyelash-like yarn is formed entirely by chain stitch.

Preferably, the roots of the threads that make up the eyelashes extend outwardly from the main body portion and connect to the waste thread portion, forming an eyelash-like pattern extending outwardly from the lace main body portion after cutting.

Preferably, the side edges of the lace knit form an undulating curvilinear profile.

The warp knitted lace according to the present invention is knitted by a warp lace knitting machine, and the warp lace knitting machine has a plurality of guide bars for knitting. At least a thread guide bar is included.

The warp knitted lace fabric of the present disclosure is capable of forming evenly distributed eyelashes with the same thickness and has a richer pattern expression than conventionally knitted weft direction eyelash lace fabrics. In addition, both the waste yarn portion and the lace main portion are warp-knitted, and continuous lace cutting can be performed by a lace cutting machine, so that the cutting efficiency is greatly improved as compared with the weft direction eyelash lace knitted fabric. Since the loop-shaped base yarn is used for knitting, the yarn extending outside does not scatter after cutting, and the yarn has good shape retention and can be straight in appearance. can. For example, by adding spandex during warp knitting, it is possible to obtain a knitted fabric that is comfortable to wear and stretches in the warp direction. Since there is no need to add additional weft direction pattern yarns to form the weft direction eyelashes, all eyelashes are formed in the same way, e.g. No color difference occurs after lash dyeing.

The following clearly and completely describes the technical solutions in the exemplary embodiments of the present invention with reference to the drawings of the present invention.

According to one embodiment of the present invention, the warp-knitted lace fabric has eyelash-like yarns uniformly distributed on at least one side edge of the warp-knitted lace extending outwardly from the side edge by a constant length. . The warp direction eyelash pattern is knitted in the warp direction by ground yarns. After knitting, the warp eyelashes are cut to form an eyelash pattern that extends to the side edges. Since the roots of the threads forming the eyelashes extend outward from the body, under the tensile force of the jacquard threads and the pattern threads, they extend outward from the ends of the body of the knitted fabric and are evenly distributed. to form an eyelash-like pattern. FIG. 5 shows an exemplary warp knitting machine embodying the invention, in which the ground yarn guide bar 1 is used to knit the ground pattern of the lace knit, the jacquard yarn guide bars 4 and 5 are combined with a mesh structure. The inlay yarn guide bar 3 is used to weave the main body of the lace fabric with the pattern yarn, and the back inlay pattern yarn guide bar 6 is used to add elastic yarn to the ground pattern. , used to achieve extensibility in knitted fabrics.

As shown in FIG. 1, the side edges of the lace knit have uniformly distributed eyelash yarns that extend outwardly at a constant length.

As shown in FIG. 2, when the warp knitting machine finishes knitting, the eyelash yarn is connected to the main body portion 1A and the waste yarn portion 1B of the knitted lace fabric.

As shown in FIG. 3, when knitting, the yarn GB-1 is knitted along the warp knitting direction in the ground pattern at the wale stitches where the eyelashes are formed according to the design requirements, and the jersey is used to form a mesh structure. By knitting the card yarns, a warp direction eyelash pattern 1zm is formed. In a conventional warp-direction eyelash lace knitted fabric, it is necessary to knit with a pattern yarn inserted in the weft direction at the highest position of the wavy side end of the lace body 1A. In the present invention, no pattern yarns inserted in the weft direction are required, and eyelashes are formed at the highest points of the waves by designing a thicker structure in the jacquard knitting process. Here, the number of course stitches of the jacquard yarn JA at the highest position is 3 to 5, realizing continuous and uniform eyelashes at the highest position. After the yarn tension is contracted, the jacquard yarn and the pattern yarn pull the chain stitch to form a wavy curve on the side edge 1a of the lace body 1A and a wavy curved portion on the waste portion 1B. The eyelash head at the lace side edge is cut along the cut contour yarn 1bb to form an outwardly extending and evenly distributed eyelash.

When knitting a warp knitted lace fabric, a ground pattern is knitted according to a specific design, which consists of looped ground yarns GB and jacquard yarns JA. As shown in FIG. 3 showing the state of threading, a looped ground thread GB is passed through a ground thread guide bar 1, and instead of the ground thread, a looped eyelash thread GB-1 is applied to the corresponding warp. It is threaded through the wale stitch where the directional eyelashes are formed. Jacquard yarn JA is completely passed through jacquard yarn guide bars 4 and 5 and spandex yarn E is completely passed through spandex yarn guide bar 6 .

When the lace knitted fabric is cut, there is a certain thickness difference between the waste yarn portion 1B and the eyelash 1zm, and it is necessary to knit a thick cut contour yarn 1bb to the side edge 1b of the waste yarn. The yarn used as the cut contour yarn 1bb is approximately 800d to 200d (denier).

The above are merely exemplary embodiments of the invention and are not intended to limit the scope of the invention. Equivalent structure or equivalent process transformations made based on the contents of the description and drawings of the present invention or directly or indirectly applied to other related technical fields shall fall within the protection scope of the present invention. .
