Description

The present invention relates to a bag-shaped warp knitted fabric and a method for producing the same. In particular, the knitted fabric structure on one side of the bag shape is basically a flat and smooth knitted fabric (hereinafter referred to as “ flat knitted fabric ”. Also referred to as “flat knitted fabric” and “flat knitted fabric”). As for the knitted fabric organization of the other side, it is related with the bag-shaped warp knitted fabric which gave the design which has a net-like knitted fabric, and its manufacturing method.

Using a warp knitting machine having two rows of needle beds and two rows of jacquard guide bars, it is known to form pants, shirts, pantyhose and the like by forming a tubular knitting.
In Patent Document 1, the front and back ground structures are knitted, and both ears (ends) of a certain dimension are knitted in a tubular shape or bag shape to a finished size while being connected with a connecting thread in the course direction. The technique which cut | disconnects the ground structure called and saves the effort of a sewing work is disclosed.

In the prior art, a knitted fabric having a design property is knitted by combining a structure having an opening such as a floral pattern, a small pattern, or a wavy pattern on both front and back surfaces of a tubular knitted fabric.
The current knitting machine has the same number of loops in the front and back fabric, and the balance between the front and back of the yarn length necessary for the knitted fabric can be determined by using a tissue with an opening (net-like knitted fabric) Knitted as a uniform knitted fabric on the front and back sides by controlling the expansion and contraction of the knitted fabric on the front and back with patterns (patterns) such as small patterns and wave patterns.
In this case, by giving a structure having an opening to the front and back knitted fabric structures, the background of the knitted fabric is stretched. However, in a clothing product having a net-like knitted fabric on the front and back, there are wrinkles, distortions, etc. Even if it does not appear to be a defect in the knitted fabric, it becomes a product with a design.

International Publication No. 2006/106975

However, in daily-use cover products such as bag-like seat covers, mattress covers, and sheets, the knitted fabric structure on one side is a flat knitted fabric having no opening, and the knitted fabric structure on the other side is There is a demand for a knitted fabric in which a design is applied to the knitted fabric textured surface by providing an underwrap between one or two stitches of jacquard, which is provided with a pattern in combination with a knitted fabric having an opening. In addition, in a garment product, a knitted fabric structure on one surface is required to be a flat knitted fabric, and a knitted fabric structure on the other surface is required to have a design having a net-shaped knitted fabric.
In such a case, it becomes a bag-like knitted fabric having a difference between the knitted fabric structures on the front and back sides. That is, the flat knitted fabric on one side is knitted with a uniform knitted fabric structure both in terms of expansion and contraction, but the knitted fabric on the other side is in the warp direction having an opening to provide a design. After the same knitting yarn as the ground texture can be moved at intervals, the knitted fabric that underlaps between one or two stitches is frequently used, or the knitted fabric to which the design is applied with jacquard is underwrapped between one or two stitches Since the knitted fabric is knitted, the composition of the knitted fabric is different between the front and back sides.
As a result, in the knitted fabric on the other side to which the design has been applied, wrinkles, distortion, etc. are likely to occur. There was a problem that it was a bad product, and it was difficult to finish wrinkles and suppress distortion etc. even after the finishing process, and it was difficult to obtain a clean product with good appearance.

  The present invention has been made in view of such a problem, and is a bag-shaped warp knitted fabric in which the ground structure on one surface and the other surface is connected along the outer line of the pattern, and the knitting on the other surface. A net-like knitted fabric that shows through, and a flat knitted fabric that forms a pattern in it, while providing an excellent design, a wrinkle-like warp knitted fabric that has less wrinkles and distortion, and a method for producing the same The purpose is to provide.

In order to achieve the above object, the bag-shaped warp knitted fabric according to the present invention is:
An integrally knitted bag-shaped warp knitted fabric having a knitted fabric on one side and a knitted fabric on the other side,
The knitted fabric on the other surface is composed of a net-like knitted fabric having an opening and a flat and smooth knitted fabric underwrapped between two needles not having an opening,
A flat smooth knitted fabric underwrapped between the two needles forms a pattern in the net-like knitted fabric,
The area ratio of the flat and smooth knitted fabric under-wrapped between the two stitches on the other surface and the net-like knitted fabric is 30% to 70% for the flat and smooth knitted fabric under-wrapped between the two stitches , The net-like knitted fabric is 30% to 70%,
The knitted fabric on the one side is composed of a flat and smooth knitted fabric underwrapped between two needles having no opening,
80% to 100% of the knitted fabric constituting the opening of the net-shaped knitted fabric is knitted by bundling 2 to 10 well knitting yarns.

It is preferable that 100% of the knitted fabric constituting the opening of the net-shaped knitted fabric is knitted by bundling knitting yarns of 2 to 8 wells.

Of the knitted fabric constituting the opening of the net-shaped knitted fabric, it is preferable that the periphery of the pattern is knitted by bundling 1-well knitting yarn.

Fineness of the knitting yarn is preferably in the range der Rukoto of 33Dtex～550dtex.

The finished density of the knitted fabric is preferably in the range of 18 to 80 courses and 16 to 60 wells .

In order to achieve the above object, a method for producing a bag-shaped warp knitted fabric according to the present invention includes:
A manufacturing method of a bag-shaped warp knitted fabric that is integrally knitted having a knitted fabric on one side and a knitted fabric on the other side,
The knitted fabric on the other surface is composed of a net-like knitted fabric having an opening and a flat and smooth knitted fabric underwrapped between two needles not having an opening,
A flat smooth knitted fabric underwrapped between the two needles forms a pattern in the net-like knitted fabric,
The area ratio of the flat and smooth knitted fabric under-wrapped between the two stitches on the other surface and the net-like knitted fabric is 30% to 70% for the flat and smooth knitted fabric under-wrapped between the two stitches , The net-like knitted fabric is 30% to 70%,
The knitted fabric on the one side is composed of a flat and smooth knitted fabric underwrapped between two needles having no opening,

The bag-shaped warp knitted fabric of the present invention comprises a net-like knitted fabric having an opening on the other side and a flat and smooth knitted fabric ( flat knitted fabric ) having no opening. The proportion of the other side of the knitted fabric is 30% to 70%, and the proportion of the net-like knitted fabric to the knitted fabric of the other side is 30% to 70 %. Excellent design properties can be obtained by the flat knitted fabric forming a pattern therein. In addition, since a large amount of knitting yarn is consumed in the flat knitted fabric portion, the excess knitting yarn length can be absorbed (adjusted) in the net knitted fabric portion that consumes little knitting yarn. Wrinkles, distortion, etc. can be prevented. In addition, since the knitted fabric on one side is made of a flat and smooth knitted fabric that is underwrapped between two stitches that do not have an opening, the knitted fabric has little expansion and contraction, is excellent in shape stability, and is applied to the design portion on the surface. The impact is reduced. Furthermore, 80% to 100% of the knitted fabric constituting the opening of the net-shaped knitted fabric is knitted by bundling 2 to 10 well knitting yarns, so that the opening of the net-shaped knitted fabric is tightened, The effect of preventing knitting and distortion of the knitted fabric is further enhanced, and an excellent design is obtained and a bag-like warp knitted fabric having a good appearance is obtained.

It is the knitting | organization organization chart which shows the connection organization | tissue of the front and back body of the bag-shaped warp knitted fabric which concerns on embodiment of this invention.

  When a design is applied to a bag-shaped warp knitted fabric, a flat underwrapped between one and two stitches on the base of an underlap structure of one or two stitches of a net-like knitted fabric having an opening in the knitted fabric It is generally performed to give a pattern such as a floral pattern, a small pattern, a wave pattern or a leaf pattern on a knitted fabric. The ratio of the net knitted fabric having an opening underwrapped between two stitches is 30% to 70% of the entire knitted fabric, and the ratio of the flat knitted fabric underwrapped between two stitches is 30% to The ratio of the net knitted fabric having an opening between one needle and the flat knitted fabric between one needle is preferably less than 20%.

If the ratio of the opening between the two stitches on the design surface exceeds 70%, the connection of the knitted fabric surface becomes weak, and the design knitted fabric is unstable and easy to move with respect to the ground structure. It tends to occur. In addition, if the ratio of the opening between the two stitches on the design surface is less than 30%, the knitted fabric surface is difficult to move, but it becomes difficult to balance the elongation of the background and the opening is difficult to see and the design is reduced. .
If the ratio of the flat structure underwrapping between the two needles constituting the pattern is less than 30%, the entire surface of the knitted fabric may be loosened, and the knitted fabric may be wrinkled or distorted. The yarn length is large, and it has the function of taking in the loose yarn length at the opening. The knitted fabric is less loose and the knitted fabric is firm, but the unevenness of appearance is small and the pattern becomes difficult to see.

  By knitting the design so that the ratio of the opening between one stitch and the flat knitted fabric between one stitch is less than 20%, loosening of the entire knitted fabric can be reduced. If it is 20% or more, the entire knitted fabric tends to be loosened, and the surface of the knitted fabric may be wrinkled or distorted.

  The ratio between the opening between one needle and the flat knitted fabric between one needle is preferably 10% to 20%, and is preferably arranged near the flat knitted fabric between two needles. If the knitted fabric between the two stitches is used appropriately in the design, the degree of elongation and looseness of the entire knitted fabric can be adjusted, and a design with a good appearance with a sense of unevenness that makes the pattern appear on the surface of the knitted fabric is possible. Become.

  In the knitting of the ground structure of the flat knitted fabric, the chain knitting may be appropriately arranged within the above range. When the ground structure is a denvi knitting or a double den knitting, the knitting yarn is knitted with the arrangement and ratio of the knitting yarn of the above design. It is preferable. When the base structure is Denbi knitting or double denvi knitting, it has the function of absorbing the looseness of the knitting yarn with the yarn of other ground structure, so there is less loosening of the knitted fabric even in the range outside the pattern ratio than the chain knitted fabric Become.

It is preferable to give the pattern by making the interval of the number of underlaps in the warp direction of the knitting yarn having the opening portion 1 to 8 courses and repeating the underwrap in the well direction. If it is less than 1 course, there is no opening, and design is not given. If it exceeds 8 courses, the knitting yarn knitting the opening tends to loosen, which may cause loosening, wrinkling, and distortion of the entire knitted fabric. .
If the back surface texture is a flat knitted fabric, the knitted fabric having an opening for applying a design to the other knitted fabric, after repeating underwrapping and overlapping the knitting yarn in the warp direction of 1-4 courses, It is preferable to underwrap the knitting yarn in the well direction in accordance with an appropriate design.

  Since the number of loops on the front and back sides is the same, how the yarn length of the knitted fabric can be adjusted with the configuration when the design is applied is a factor that reduces wrinkles, distortion, and the like.

  The ratio of the net-like knitted fabric having an opening between one or two stitches is less than 20%. If it is less than 20%, the knitted fabric to which the design is applied to the front knitted fabric is not easily affected by the knitted fabric on the back surface, the distortion is small, and the pattern shape is kept stable. If it is 20% or more, the entire knitted fabric is loosened, the finished shape becomes unstable, and the appearance may be deteriorated. In use, the knitted fabric is weakly connected, so that the strength is insufficient, and a bag-shaped warp knitted fabric with a risk of unraveling and tearing is obtained.

  What is necessary is just to select the thread | yarn used for this embodiment suitably in the range of 33 dtex-550 dtex. If it is less than 33 dtex, depending on the product (product) application, there is a concern that the strength, tearing, and wear will be insufficient in terms of performance. Further, if it exceeds 550 dtex, the strength, wear and other performance of the knitted fabric tend to improve, but the product itself becomes thicker, heavier, less flexible, difficult to handle, and there is a concern about the texture. is there.

  The knitting machine of this embodiment is in a range of 16 gauge to 30 gauge, and may be appropriately selected according to the application.

  The quality of the knitted fabric of the present embodiment is in the range of 18 to 80 courses, the finished well is in the range of 16 to 60 wells, and the yarn to be used may be appropriately selected depending on the application. If the finished course is less than 18 courses, the loop tends to elongate easily, the knitted fabric becomes loose, the appearance of the product and the amount of finish are likely to be uneven, and the strength such as tearing is low, making it difficult to use practically. There is a tendency. If it exceeds 80 courses, the knitted fabric becomes heavy and hard, so when used on the skin side, the texture is hard and not only feels uncomfortable, but also difficult to handle in use.

  The knitting yarn used in the present embodiment is not particularly limited, and may be appropriately selected according to usage such as nylon, polyester, rayon spun yarn, cotton yarn, natural yarn, functional yarn.

  The well (number of knitting yarns) constituting the net is preferably composed of 2 wells (2 knitting yarns) to 10 wells (10 knitting yarns). In the knitting of the net-like knitted fabric occupying the surface, if it is composed of one well (one knitting yarn), the required yarn length is small, but wrinkles, distortion and knitted fabric floating of the net-like knitted fabric increase. , There is a risk that it looks bad. This is because all the yarn lengths supplied are the same, and the knitted fabric that does not require the yarn length becomes loose, causing wrinkles and distortion on the surface of the knitted fabric.

  If it is 2 wells (2 knitting yarns) or more, if the two knitting yarns are under-wrapped between two stitches with jacquard yarn, the yarn length increases and the feeling of tightening increases, so that the knitted fabric loosens and wrinkles. , Good for distortion. The net well (number of knitting yarns) may be selected within the range of design and function, and may be appropriately selected between 2 wells and 10 wells.

  When the back surface texture is underwrapped between the chain stitch and the two stitches, the stretch of the knitted fabric is small, the shape stability is excellent, and the influence on the design portion of the surface is small.

  In the surface structure of the surface design, the net-like knitted fabric part is made by creating a design at a certain interval in the weft direction, and then knitting an underlap flat knitted fabric part between two stitches in a line of weft. The excess yarn length can be absorbed (adjusted) at the net-shaped knitted fabric, and wrinkles, distortion, and lifting can be eliminated. Further, the flat knitted fabric portion is preferably knitted with a width of about 2 to 10 cm in a line in the weft direction so as not to obstruct the design. The flat knitted fabric portion can be expected to have an effect of suppressing wrinkles, distortion, and lifting by knitting in the weft direction or diagonal line shape. In the case of a large bag-shaped product, by connecting the front and back at a predetermined interval, a small bag can be formed and wrinkles of the knitted fabric can be eliminated. Furthermore, it can be made into a small bag-like and quilted bag-like product, and by connecting the front and back, a lot of yarn length is consumed, and a bag-like knitted fabric having a good wrinkle and distortion is obtained.

  The knitting is easy if the design of the jacquard yarn is considered to be a stretchable processed yarn. Among them, it is preferable to use a polyurethane yarn covering yarn.

  The bag-shaped warp knitted fabric according to the embodiment of the present invention will be described in more detail with reference to the drawings.

  As shown in FIG. 1, a double raschel knitting machine DR for knitting a warp knitted fabric 10 including a bag-shaped warp knitted fabric according to the present embodiment includes a large number of front and rear needles arranged in parallel in the knitting machine width direction. N1 and N2. The double raschel knitting machine DR also has front and rear needle hooks (trick plates) T1, T2. The double raschel knitting machine DR has guide bars (バ ー) L1, L2, L3, L4, L5, and L6 used for knitting, and two of them are jacquard guide bars (Jacquard 筬) L3 and L4. It is. Guide bars L1, L2, and L3 are used for knitting the front knitted fabric 2a, and guide bars L4, L5, and L6 are used for knitting the back knitted fabric 2b. The knitting yarns Y1, Y2, Y3, Y4, Y5, and Y6 are threaded through the guide portions G1, G2, G3, G4, G5, and G6 of the guide bars L1 to L6, respectively. Extracted from beams B1, B2, B3, B4, B5, and B6, respectively. Thus, the warp knitted fabric 10 including the bag-shaped warp knitted fabric according to the present embodiment is manufactured by knitting the front knitted fabric 2a and the back knitted fabric 2b using the double raschel knitting machine DR. The

  As shown in FIG. 2, in the method for manufacturing a bag-shaped warp knitted fabric according to this embodiment, two types of warp knitted fabrics 10a and 10b for different products are arranged in the knitting width direction, and the warp knitted fabric 10 is knitted simultaneously. Knit in the vertical direction. Here, the ground textures of the surface knitted fabrics 2aa and 2ba are net-shaped knitted fabrics having openings. On the other hand, the ground structures of the back knitted fabrics 2ab and 2bb shown by partially breaking the front knitted fabrics 2aa and 2ba are flat knitted fabrics having no openings. The back knitted fabrics 2ab and 2bb of the front and back knitted fabric portions of the warp knitted fabric 10 are knitted mainly with a heel that is underwrapped between two stitches to form a flat and smooth ground texture (flat knitted fabric). On the other hand, in the surface knitted fabrics 2aa and 2ba, a net-like ground structure (net-shaped knitted fabric) knitted between one and two stitches and a flat knitted fabric under-wrapped between one or two stitches (Design 3a, 3b) is combined and the design is expressed on the surface of the knitted fabric.

  Patterns 3a and 3b made of flat knitted fabric are arranged almost evenly on the ground texture of the surface knitted fabrics 2aa and 2ba of the net knitted fabric. The ratio of the area of the pattern 3a, 3b made of a flat knitted fabric to the surface surrounded by the outer lines (bridging lines and cut lines) 4a, 4b of the pattern that divides the product is 30% to 70%. On the other hand, the ratio of the area occupied by the ground structure of the surface knitted fabrics 2aa and 2ba made of a net-shaped knitted fabric to the surface surrounded by the outer lines 4a and 4b of the pattern dividing the product is 30% to 70%. The warp knitted fabric 10 is knitted in the arrow direction (knitting longitudinal direction) while forming the ear tissue 5 and the knitted fabric 6 instead of the pattern together with the front knitted fabrics 2aa and 2ba and the back knitted fabrics 2ab and 2bb. When the warp knitted fabric 10 is knitted by a predetermined length, the warp knitted fabric 10 is removed from the double raschel knitting machine DR and subjected to a processing step such as dyeing. Thereafter, the knitted fabric outside the outer lines 4a and 4b of the pattern is cut along the outer lines 4a and 4b of the pattern.

  A bag-like warp knitted fabric according to this embodiment in which the outer knitted fabric of the outer lines 4a and 4b is cut is shown in FIGS. As shown in FIG. 3, an example of the bag-like warp knitted fabric according to this embodiment is a T-shirt 1a. Other clothing products such as pants and inners can be produced in the same manner. In the T-shirt 1a, the ground structure of the surface knitted fabric 2aa is formed of a net-shaped knitted fabric, and the pattern portion 3a of the surface knitted fabric 2aa is formed of a flat knitted fabric. And all the back surface knitted fabrics 2ab consist of flat knitted fabrics. The proportion of the flat knitted fabric (pattern 3a) in the surface knitted fabric 2aa is 40%, and the proportion of the net knitted fabric (ground texture) in the surface knitted fabric 2aa is 60%.

Here, the ratio of the area occupied by the flat knitted fabric (pattern 3a) to the surface knitted fabric 2aa is preferably within a range of 30% to 70%, and the net knitted fabric (ground texture) is formed on the surface knitted fabric 2aa. The ratio of the occupied area is preferably in the range of 30% to 70%.
When the ratio of the area occupied by the flat knitted fabric to the surface knitted fabric 2aa is less than 30%, the effect of absorbing the knitting yarn length by consuming a large amount of knitting yarn at the flat knitted fabric portion as will be described later. May not be sufficiently obtained. On the other hand, if the proportion of the area occupied by the flat knitted fabric in the surface knitted fabric 2aa exceeds 70%, the proportion of the net-shaped knitted fabric may be reduced, and an excellent design property may not be obtained.
If the ratio of the area occupied by the net-like knitted fabric to the surface knitted fabric 2aa is less than 30%, the ratio of the net-like knitted fabric decreases, and there is a possibility that excellent design properties cannot be obtained. On the other hand, when the ratio of the area of the net knitted fabric to the surface knitted fabric 2aa exceeds 70%, the knitting yarn length is absorbed by consuming a long amount of knitting yarn in a flat knitted fabric portion as described later. The (adjustment) effect may not be sufficiently obtained.

  In the T-shirt 1a, excellent design properties are obtained by the net-like knitted fabric portion that can be seen through and the flat knitted fabric portion that forms the pattern 3a therein. Further, since the knitting yarn is consumed in a long and large amount in the flat knitted fabric portion, the excess knitting yarn length can be absorbed (adjusted) in the net knitted fabric portion which consumes little knitting yarn, and the wrinkle of the knitted fabric is reduced. , Can prevent distortion.

  Furthermore, in the T-shirt 1a according to this embodiment, the knitted fabric at the opening of the net-shaped knitted fabric portion is knitted by bundling 2-well knitting yarns. The net structure of the bag-shaped warp knitted fabric according to the present embodiment will be described with reference to FIGS.

  As shown in FIG. 6, in the case of a net constructed by bundling only one-well knitting yarn (hereinafter referred to as “one-well net”), the knitting yarn Ya is bundled into only one around the opening 12a. It is organized. For this reason, when the net-like knitted fabric is knitted only with the net structure of one well net, the opening portion 12a is easy to expand, and the knitting yarn bundled with the knitting yarn Ya is not consumed, so that the knitting yarn is easily left and wrinkles of the knitted fabric are eliminated. Cause distortion.

  On the other hand, as shown in FIG. 7, in the case of a net configured by bundling 2-well knitting yarns, two knitting yarns Yb are knitted around the opening 12b. Therefore, the opening 12b is tightened and is difficult to spread, and the knitting yarn for bundling the two knitting yarns Yb is consumed for a long time, so that the remainder of the knitting yarn is reduced, and wrinkling, distortion, etc. of the knitted fabric can be prevented. As shown in FIG. 8, in the case of a net configured by bundling 3-well knitting yarns, three knitting yarns Yc are knitted around the opening 12c. Therefore, the tightening effect of the opening 12c and the effect of consuming the knitting yarn surplus by bundling three knitting yarns Yc are further improved, and wrinkling and distortion of the knitted fabric can be more reliably prevented.

  In this way, a garment product of the T-shirt 1a can be manufactured as a bag-shaped warp knitted fabric that achieves both excellent design properties and good appearance without wrinkles, distortion, looseness, swelling and sagging.

  In the present embodiment, the back knitted fabric 2ab is all made of a flat knitted fabric. However, the present invention is not limited to this, and a net knitted fabric in which a part of the back knitted fabric 2ab has an opening. It is also possible to organize it as follows. In this case, the ratio of the area occupied by the net-shaped knitted fabric portion in the back knitted fabric is preferably less than 20%. In the present embodiment, the knitted fabric at the opening of the net-shaped knitted fabric is all knitted by bundling 2-well knitting yarns, but within a range of 20% or less of the net-shaped knitted fabric area, You may mix the network organization of 1 well net. In particular, since only the periphery of the pattern 3a has a 1-well net structure, the pattern 3a appears to be more lifted, so that more excellent design can be imparted.

  As shown in FIG.4 and FIG.5, the other example of the bag-shaped warp knitted fabric which concerns on this embodiment is the bag-shaped cover 1b. Other cover products such as sheets, sheets and mattresses can be produced in the same manner. In the bag-shaped cover 1b, as shown in FIG. 4, the ground structure of the surface knitted fabric 2ba is made of a net-like knitted fabric, and the pattern portion 3b of the surface knitted fabric 2ba is made of a flat knitted fabric. And as shown in FIG. 5, all back surface knitted fabrics 2bb consist of flat knitted fabrics. The proportion of the flat knitted fabric (pattern portion 3b) in the surface knitted fabric 2ba is 50%, and the proportion of the net knitted fabric (ground texture) in the surface knitted fabric 2ba is 50%. In the bag-like cover 1b, excellent design is obtained by the net-like knitted fabric that can be seen through and the flat knitted fabric that forms the pattern 3b therein. In addition, since a large amount of knitting yarn is consumed in the flat knitted fabric portion, the excess knitting yarn length can be absorbed in the net knitted fabric portion that consumes little knitting yarn. Distortion can be prevented.

  Furthermore, in the bag-like cover 1b according to the present embodiment, the knitted fabric at the opening of the net-shaped knitted fabric is knitted by bundling three-well knitting yarns. As shown in FIG. 8, in the case of a net configured by bundling 3-well knitting yarns, three knitting yarns Yc are knitted around the opening 12c. Accordingly, the tightening effect of the opening 12c and the knitting yarn consumption effect by bundling three knitting yarns Yc are more excellent, and wrinkling and distortion of the knitted fabric can be more reliably prevented.

  In this manner, a cover product such as the bag-shaped cover 1b can be manufactured as a bag-shaped warp knitted fabric that has excellent design properties and is compatible with good appearance without wrinkles, distortion, slackness, and swelling.

  In the present embodiment, the back knitted fabric 2bb is made of a flat knitted fabric. However, the present invention is not limited to this. A net knitted fabric in which a part of the back knitted fabric 2bb has an opening. It is also possible to organize it as follows. In this case, the ratio of the area occupied by the net-shaped knitted fabric portion in the back knitted fabric is preferably less than 20%. In the present embodiment, the knitted fabric at the opening of the net-shaped knitted fabric is all knitted by bundling three-well knitting yarns, but within a range of 20% or less of the net-shaped knitted fabric area. One well net organization may be mixed. In particular, since only the periphery of the pattern 3b has a one-well net structure, the pattern 3b appears to be more lifted, and thus more excellent design can be imparted.

  Next, a basic knitting structure of the tissue part of the bag-shaped warp knitted fabric according to the present embodiment will be described with reference to FIGS. 9 to 11. FIG. 9 is a knitting organization diagram showing a basic knitting organization of the organization part of the bag-shaped warp knitted fabric according to the present embodiment. FIG. 10 is a knitting organization diagram showing a basic knitting organization of the front and back bodies of the bag-shaped warp knitted fabric according to the present embodiment. FIG. 11 is a knitting structure diagram showing a basic connected structure of the front and back bodies of the bag-shaped warp knitted fabric according to the present embodiment.

  The organization 1 to organization 4 shown in FIG. 9 represent a basic organization chart of the organization part. The organization 1 and the organization 2 represent knitting of a flat knitted fabric. The organization 3 and the organization 4 represent knitting of a net-like knitted fabric having an opening. In the case of a net-like knitted fabric having an opening, after knitting at a desired interval in the warp direction, the opening is knitted by underwrapping the knitting yarn between one and two stitches at a certain interval. If the underlap is not always made between one and two stitches, the yarn length becomes short and short, and there is a possibility that problems such as wrinkles and distortion may occur due to the remaining knitting yarn.

  In the structure 1 shown in FIG. 9, the knitting yarn constituting the ground structure is a knitted fabric underlaid between one stitch, and the structure 2 is a knitting where the knitting yarn constituting the ground structure is underwrapped between two needles. It is the earth. In the ground structure of the structure 2, since the knitting yarn is underwrapped between two stitches, the yarn length is long and many, but the knitted fabric is thick and becomes a firm knitted fabric. In the case of a product having a large shape such as a cylinder, a bag, or a cover, or a product that requires strength, a knitted fabric that is underwrapped between two stitches is often used. When the knitted fabric is knitted with the ground structure such as the structure 1 and the structure 2, the loop of the knitted fabric is uniform and the movement of the sinker loop is constant, so that the yarn length to be fed and the yarn tension are also constant. The ground texture is a flat texture with uniform loops.

The organization 3 and the organization 4 shown in FIG. 9 are basic organizations that organize the opening. The size of the opening is reduced by knitting at short intervals in the warp direction, increasing the number of underlaps in the well direction, or increasing the number of underlaps. The yarn length varies greatly depending on the size of the opening and the length of the underwrap in the warp direction of the knitting yarn.
When underwrapping is performed between two needles as in the structure 4, the yarn length increases and the knitted fabric at the opening becomes a firm knitted fabric. Also, underlap between two or more stitches tends to draw in the loop of the background, and there is a tendency for the space between the opening and the opening to widen, but in the case of a large cylindrical or bag-like cover, the knitted fabric itself Due to the large size, the product tends to be heavy.
It is only necessary to appropriately adopt an underlap between one stitch as in the structure 3, but if many are used, the knitted fabric such as a large cylindrical or bag-like cover is easily deformed due to the weight of the knitted fabric. It tends to be a product that is easy to use, has low strength, and remains a concern for appearance and security.

  In the present embodiment, in a knitted fabric for producing a product having a large size such as a cylindrical or bag-shaped cover, the ground structure on one of the front and back surfaces is a flat knitted fabric and the other surface is open. The present inventors have found a knitting method in which a knitted fabric having a design and an underlap between one or two stitches is knitted so that the product has a good appearance with few wrinkles and distortions.

  For example, either one of the front and back surfaces is a flat knitted fabric of the structure 2 and is knitted into a long (1 m or more) bag shape underlapped between two needles and a weft (1 m or more) bag shape, The design of the surface is imparted with design, and when the knitted structure 2 and the structure 3 or the structure 2 and the structure 4 are combined, the yarn length to be supplied is different. The flat knitted fabric 2 is combined in consideration of the ratio of fastening to the entire knitted fabric of the organization 2, the organization 3, and the organization 4 constituting the knitted fabric of the design imparting surface.

  As shown in FIG. 10, in the basic knitting structure of the front and back bodies of the bag-shaped warp knitted fabric in the present embodiment, the guide bar (バ ー) L1 to L6 of the double raschel knitting machine DR shown in FIG. Only the bars L2, L3, L4, L5 are used for knitting. Two of these are jacquard guide bars (Jacquard baskets) L3 and L4. As shown in FIG. 10, chain knitting is performed on the guide bars L2 and L5, and knitting is performed on the jacquard guide bars L3 and L4 so as to underlap between one stitch.

  As shown in FIG. 11, in the basic connected structure of the front and back bodies of the bag-shaped warp knitted fabric in the present embodiment, guides (guides) L1 to L6 of the double raschel knitting machine DR shown in FIG. Only the bars L2, L3, L4, L5 are used for knitting. Two of these are jacquard guide bars (Jacquard baskets) L3 and L4. As shown in FIG. 11, chain knitting is performed on the guide bars L2 and L5, and knitting is performed on the jacquard guide bars L3 and L4 so as to underlap between one stitch.
