Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a narrow width knitting tape having a variable width and a method for manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, as a narrow tape used for shoulder straps of women's underwear, the width of the central portion has been changed so as to reduce the bite into the shoulder portion. Various proposals have been made. However, in the conventional proposal, whether it is woven or knitted, the width is changed by utilizing the high elasticity (high elasticity) of the warp direction yarn and the weft direction yarn used as the basic design of the tape. (For example, JP-A-6-27)
2103 and JP-A-7-48753).
As described above, in the structure using the highly elastic yarn, the expansion and contraction becomes unstable depending on the structure with other yarns, it is very difficult to adjust the width dimension, and variations in weaving or knitting are likely to occur. It was troublesome.

For this reason, the narrow width knitting tape of the present invention has been developed after intensive research so that the width of the narrow width tape can be changed without using any highly elastic yarn as the basic structure. is there.

[0004]

A narrow-width knitting tape having a width change according to the present invention is a warp-knitted narrow-width knitting tape having a width change, as described in claim 1. A wide knitted portion and a narrowly knitted portion are provided with a transitional portion gradually changing in width between the two portions,
It is characterized in that these portions are formed by changing both or one of the tension and the yarn amount with respect to the yarn.

The narrow width knitting tape having the width change according to the above-mentioned structure does not depend on the high elasticity (high elasticity) of the yarn itself, and changes in the tension and / or the yarn amount (the yarn supply amount) with respect to the yarn. Since the part where the width is wide and the part where the width is narrow are formed through the transitional part where the width changes gradually between both parts, it does not depend on the warp elongation and the weft elongation. Instability does not occur, it is very stable as a knitting structure, and it is possible to provide a narrow knitting tape with desired width changes, which is suitable not only for shoulder straps for women's underwear but also for various purposes. A narrow knitting tape can be provided.

In the method for manufacturing the narrow width knitting tape having the width change, as described in claim 2, as the portion for wide knitting, is the tension increased for the yarn in the warp direction? Knitting with a small amount of yarn, weakening the tension for yarns in the weft direction or increasing the amount of yarns, and knitting with a narrow width Knit with a weaker or larger amount of yarn, and with a higher tension for the weft direction yarn or with a smaller amount of yarn, between the part where the width is wide and the part where the width is narrow The knitting is characterized in that the width is changed by the required length through the transition portion.

According to such a manufacturing method, even if the high elasticity (high elasticity) of the yarn is not used, the width of the knitting is wide depending on the strength of the warp knitting device and the yarn amount (yarn supply amount). And knitting can be done easily through the transitional part where the width changes gradually, knitting with a stable dimension can be realized, and the dimensional ratio of the wide knitting width and the narrow knitting width Is also a method that makes it easy to adjust various dimensions.
It becomes easy to provide a narrow knitting tape having various width changes.

Further, as described in claim 3, as a portion for wide knitting, a large number of stitches per fixed length are knitted, and for a portion of narrow width, a stitch per constant length is knitted. Using a method for manufacturing a narrow width knitting tape, which is characterized by knitting a small number of pieces and knitting them by providing a degree change with a width change by a required length through a transitional portion that gradually changes between both parts. According to the second aspect, it is possible to easily manufacture the narrow tape having the width change.

Incidentally, knitting in which the wide portion and the narrow portion have the same number of stitches (the number of stitches within a fixed length) can of course be handled by the function of the warp knitting machine.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described below with reference to the drawings. First, in FIG. 1 showing an outline of a narrow width knitting tape 1 having a width change, A indicates a wide knitted portion, B indicates a transitional portion where the width changes gradually, and C indicates a narrow knitted portion. ing.

2 and 3 are organization charts shown as an example of the knitting organization in each portion of FIG. However, in FIG. 3, the number of yarns is omitted to facilitate understanding of the knitting structure, and the width is not changed for convenience sake. FIG. 4 shows the knitting structure of each yarn. 2 to 4, 10 is a chain stitch yarn in which chain stitches are formed for each course and positioned in each wale and knitted in a stuffed manner. 11 is a 4 stitch wale and is woven while hanging on the chain stitch yarn 10. An insert yarn in a weft direction, and 12 is an insert yarn in the weft direction, which is made to meander while flying by 3 wales each and hanging on the chain stitch yarn 10. The insertion yarns 11 and 12 increase the density of the narrow knitting tape 1 to give a feeling of thickness due to the mutual overlapping of the yarns. 13 is 5 per 1 wale
The yarn is inserted in the warp direction while flying over the course and being hung on the chain stitch yarn 10 to be a reinforcing yarn in terms of knitting structure.

Each of the above-mentioned yarns is a normal non-stretchable yarn which is not called a highly elastic yarn (high elastic yarn), and is made of, for example, polyester yarn or nylon yarn. The narrow width knitting tape 1 having the width change is provided with a transition portion B having a gradually changing width between a portion A having a wide width and a portion C having a narrow width and both portions AC. Since it is knitted by warp knitting and uses a non-stretchable yarn as described above, the tension (pull-in strength) and the amount of yarn (the amount of yarn supplied) to the yarn do not depend on the expansion and contraction of the yarn.
It has a great feature in that it is formed by the change of both or one of the above.

The narrow tape 1 having the above characteristics is
The knitting structure and the number of yarns described above are not limited.
An embodiment of the invention for producing the narrow-width knitting tape 1 of the present invention having the above-described structure using a warp knitting machine will be described below with reference to the organization chart of FIG.

First, as the part A for wide knitting,
The chain stitch yarn 10 which is the warp direction yarn and the warp direction insertion yarn 13 which serves as the reinforcing yarn are knitted by increasing the tension or decreasing the yarn amount. For the two types of insertion yarns 11 and 12 which are weft direction yarns, on the contrary, the tension is weakened or the yarn amount is increased to knit. Next, as the portion C to be knitted with a narrow width, a chain stitch yarn 10 which is a warp direction yarn and a warp direction insertion yarn 13 are formed.
On the other hand, knit with a lower tension or a larger amount of yarn. In addition, two types of insertion yarns 11 which are weft direction yarns,
On the other hand, with respect to No. 12, the knitting may be performed by increasing the tension or reducing the yarn amount. At the transition portion, the tension or the yarn amount gradually changes, but the knitting is wide. At the transition portion B from the portion A to the narrowly knitted portion C, and conversely, at the transition portion B from the narrowly knitted portion C to the wide knitted portion A, the change in the tension or the yarn amount is completely reverse. Doing is a natural embodiment.

In the case of FIG. 2 described above, the portion A to be knitted with a wider width in terms of the manufacturing method is knitted with a large number of stitches per fixed length to form a dense knitting portion, and the knitting with a narrow width is performed. The portion C is knitted with a small number of stitches per fixed length to form a coarse knitting portion, and a transitional portion B that gradually changes between both portions AC is provided with a stitch change for each required length along with a width change. Since the knitting is performed by knitting, the knitting can be performed in the same embodiment by changing the stitch adjusting function of the device of the warp knitting machine.

In the second change of FIG. 2, the transitional portion B from the wide knitted portion to the narrow knitted portion C is changed.
It is also a matter of course that the degree change is completely opposite in the transition portion B in the opposite direction. Further, a modified example of the embodiment will be described with reference to the organization charts of FIGS. However, in FIG. 5, the number of yarns to be included in the knitting width is omitted for the sake of clarity, and FIG.
Similarly, the number of yarns is omitted in order to make the knitting structure easy to understand, and the width is not changed for convenience sake.

In the case of the modified example shown in FIGS. 5 to 7, three insertion yarns 14, 15, 16 in the warp direction are added to the basic knitting structure of FIGS. 2 to 4 described above. In a modified form, only one piece is shown for convenience of illustration, but it is sequentially inserted into a wale that can be inserted within the width of the narrow knitting tape 1, and the insertion yarn 14 is a wide knitted portion. In A, there is no change to the adjacent wales, but in the part C where the width is narrowly knitted, it is changed to every adjacent course especially to the adjacent wales, and when the part C where the width is knitted becomes coarse It is designed to be strong and durable. Each of the insertion threads 14, 15 and 16 is made of a non-stretchable thread such as a polyester thread or a nylon thread, and the insertion thread 15 in the warp direction is a highly stretchable thread such as a polyurethane thread. Case and other insert thread 1
It is also possible to knit with respect to No. 4 by using the same highly elastic yarn. Further, as the insertion yarn 16, a pile yarn partially protruding on the surface is suitable. However, the basic design of the portion A for wide knitting, the portion C for narrow knitting, and the transition portion B between the two portions is knitted with non-stretchable yarns without depending on the stretching of the yarns. The effect of the warp-direction insertion yarn added to the basic knitting can be easily grasped, and a knitting structure having a high density can be easily provided.

Furthermore, various known knitting structures can be carried out, for example, insertion yarns in the weft direction can be added and the knitting structure can be carried out. Also, known knitting structures having different thicknesses at the width center and the width end are known. A knitting structure may be adopted and implemented.

[0019]

According to the narrow width knitting tape according to the first aspect of the present invention described above, a wide knitted portion and a narrow knitted portion are knitted without depending on the expansion and contraction of the yarn. The part and the part are provided with a transitional part having a gradually changing width between the parts, and these parts are formed by changing the tension and / or the amount of the yarn with respect to the yarn, or one of them, and therefore, it is basically the same as in the prior art. It is possible to eliminate variations in width dimension due to unstable stretch when a highly stretchable yarn is used in the structure, and it is possible to provide a narrow width knitting tape in which the width dimension to be changed is stable.

Further, it is used for various purposes such as shoulder straps for women's underwear, camera straps, belts, suspenders, straps for goggles and the like. Further, according to the method for manufacturing a narrow width knitting tape having a width change according to the present invention, the wide knitting portion and the narrow knitting portion are provided with respect to the warp direction yarn and the weft direction yarn. The size of the yarn is stable compared to the conventional knitting method that tends to become unstable due to the high elasticity of the yarn itself because it can be knitted in a state in which the width changes reasonably depending on the tension applied or the amount of yarn. It is possible to mass-produce thin and narrow knitting tapes with varying widths easily and with a unique effect that is suitable for producing various kinds of wide knitting parts and narrow knitting parts with different dimensional ratios. I can give you.
