Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming a picot of a scalloped portion in a warp-knit narrow lace fabric used as a border decoration for women's underwear, outer clothing, etc.

Traditionally, this type of warp-knitted narrow lace fabric has been knitted using a Raschel knitting machine, but it is usually knitted over the full width of the needle installation, so-called all-over lace, and after knitting, this is knitted into thin units one by one. The product is separated into wide lace fabrics.

This separation can be done in two ways: using a cutter, manually or mechanically to separate the threads, and separating the knitted threads by pulling them out after processing.

However, among the former methods using a cutter, manual separation is not only inefficient, but also difficult to finish so that the lace ends follow the curved shape of the scalloped part, and the thread ends remain at the cut end. , the lace end cannot be formed neatly.

Also, when using mechanical equipment, there are almost the same drawbacks as when using manual equipment, except for efficiency.

Moreover, in the case of a tissue obtained by such a separation method, even if the scalloped portion could be formed into a curved shape, it was impossible to make the picot appear so as to protrude from the scalloped portion (see FIG. 5).

In addition, in the case of the latter type of texture, the lace edges are usually only close to a straight line, and the picots can only be made to appear close to this straight line (see Figure 6), resulting in a curved selvage. It was not possible to form a structure in which the picot protruded beyond the scalloped part exhibiting .

This invention has been made to eliminate these drawbacks, and provides a method for making a scalloped part appear in a curved shape in a narrow warp-knitted lace fabric, and also forming a picot that clearly protrudes from the scalloped part. This is what we are trying to provide.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a tissue chart showing an example of knitting a narrow lace fabric, in which A shows the ground texture, that is, the pattern forming part, B shows the scalloped part, C shows the knitting positions of the picot part, and N shows the needle position.

Reference numerals 1 and 2 denote warp yarns for forming the base fabric arranged in the base texture A, which are insoluble yarns, such as nylon filament yarns.

Then, the warp yarn 1 forms a stitch row in the wale direction while knitting a chain loop in each course, and the warp yarn 2 is inserted into the stitch row of the same wale for 3 courses, and then moves to the adjacent needle and forms 3 stitch rows in the wale direction. After a course is inserted, the knitting process is repeated by returning to the original needle and inserting 3 courses into the stitch row of that wale to form a square-grained ground texture.
It is not limited to this organization.

3 is a scallop-forming yarn placed in the scalloped part B at the edge of the ground weave A, which is placed over several wales (for nine needles in the figure), and is wrapped around each needle in a predetermined course. It is knitted so as to be transferred to the adjacent wale and follow the curved shape of the scalloped portion B.

That is, each scalloped yarn 3 has a shape shown at the bottom of the figure.
A chain stitch is formed over several courses in the wales of , and then sequentially transferred to a plurality of adjacent wales b = i in one direction (to the left in the case of the figure), and a chain stitch is knitted in each wale, Next, a plurality of adjacent wales j = in the opposite direction (in the case of the figure, to the right).

A chain stitch is knitted in each wale by sequentially moving to the knitting process, and by repeating such knitting, a curved scalloped part B is knitted at the edge of the ground weave.

In the case of the illustrated embodiment, the scalloped portion B is knitted as described above and is indented in the left direction in a dogleg shape. overlaps with ground organization A.

4 is the hemming thread arranged on the scalloped part B, in the case of the figure,
Two needles are attached to the outer end of the scalloped portion B, and one needle is attached to the inner end thereof, and the needles are wrapped around the needle so as to follow the curved shape of the scalloped portion B, and are inserted while being knitted into the stitch row in an appropriate course.

When a plurality of hemming threads 4 are interleaved in this manner, the structure of the scalloped portion B can be further reinforced.

Reference numeral 5 denotes a picot-revealing warp arranged adjacent to the outer edge of the scalloped portion B, which is threaded through the same reed as the warp 1, and is made of soluble yarn, for example, water-soluble vinylon yarn.
It is arranged for the needle between the wales located from the wale located 1 gage outward from the most curved outer end of the edge of the scalloped portion B to the wale located 2 gage outward from the most protruding outer end (as shown in the figure). (displayed for 10 needles), chain loops are knitted in every course, similar to warp yarn 1 (chain loops are omitted at locations where they overlap with scalloped yarn 3)
.

6 is a picot forming yarn, and while knitting it to the scalloped part B, it is swung horizontally by 2 gauges every predetermined course.
After the stitches are made to protrude more and are knitted into a stitch row consisting of chain loops of the warp threads 5, they are turned back and knitted to the scalloped part B, and the knitting is repeated to make the knitting protrude into a U-shape.

After knitting in this way, this fabric is immersed in water to dissolve the warp threads 5, which are soluble threads, so that the curved scalloped portion and the picot P protruding from this scalloped portion are clearly exposed. (Figures 2 and 3).

FIG. 4 is a knitting organization chart showing another embodiment of the present invention. The difference from the organization shown in FIG. 1 is that the warp threads 5', which are soluble yarns,
It is knitted along the curved shape of the scalloped part.

When knitting in this way, the warp 5' can be knitted by placing it in the wale between d, that is, in the five needles.
The amount of warp yarns 5' consumed is small, making it very economical.

After knitting in this manner, by dissolving the warp threads 5' which are soluble threads, the scalloped portion and picot can be exposed in the same manner as described above.

In the above-mentioned knitting, pattern yarns are appropriately arranged and knitted, but the explanation is omitted because it is not directly related to this invention.

Furthermore, in the above knitting, explanation has been given on the knitting of one unit of narrow lace fabric, but multiple lace fabrics are knitted simultaneously over the entire width of the needle, and after knitting, the soluble yarn is dissolved to create narrow lace fabrics one unit at a time. It may be separated into different width lace fabrics.

As described above, according to the present invention, the scallop-forming yarn is knitted along the curved shape of the scalloped portion, and the picot-forming yarn is laterally swung for each predetermined course to protrude from the scalloped portion. After knitting, the soluble threads are knitted into a row of stitches, and the hikot is revealed by dissolving the soluble threads, which not only makes it extremely easy to form the hikot, but also creates a clearly curved scalloped part. In addition, each picot protrudes separately from this scalloped portion, resulting in a series of picots also being arranged in a curved shape, and each picot having a distinct structure.

Furthermore, the indented portion of the scalloped portion overlaps with the ground structure, thereby making it possible to obtain a planar scalloped portion.

Moreover, according to this invention, there is no need to use a cutter or to remove the sutures when forming the picot, so it is possible to form a scalloped part in a curved shape with large undulations and form the picot to protrude from this scalloped part. Not only that, but it also makes it extremely easy to make the picots of any desired protrusion length or to set the length of the picots in stages, making warp-knitted narrow lace fabric for edge decorations with excellent commercial value available at low cost. It becomes possible to manufacture
