Description

  The present invention relates to a double raschel fabric composed of two front and back ground structures and connecting yarns connecting them, and in particular, a collar having a plurality of ridges on at least one ground structure side. This is related to a double raschel area.

  Conventionally, double raschel fabrics composed of two front and back ground structures and connecting yarns that connect them are widely used for applications such as clothing, industrial materials, and vehicle interior materials because of their cushioning and repulsive advantages. .

  In recent years, a knitted fabric having a plurality of ridge-shaped protrusions, that is, ridges on one side of the front and back sides has been proposed as a further design effect in such a double raschel fabric.

  For example, in Patent Document 1, a surface knitted fabric of a three-dimensional solid knitted fabric is formed with a strip-shaped knitted fabric portion extending in the well direction (knitting direction) by continuous stitching of stitches in a plurality of continuous wells, and adjacent to the strip-shaped knitted fabric portions. By arranging them apart from each other, a three-dimensional solid knitted fabric in which a number of protruding ridges composed of a belt-shaped knitted fabric portion and a connecting yarn are formed along the well direction, and adjacent belt-shaped knitting Positions corresponding to the region directly below the belt-like knitted fabric part that constitutes the adjacent heel part by improving the seating feeling by intermittently connecting the ground parts in the well direction. It is disclosed that the buckling is effectively prevented by connecting to the back knitted fabric.

  In Patent Document 2, in a double raschel ground composed of two ground structures on the front and back and a connecting thread that connects them, strip-shaped narrow portions are arranged side by side at an appropriate interval on the front side, and the strip-shaped narrow portions are connected. A ridge-like double raschel fabric is formed by connecting to the lining structure portion with a thread to form a ridge-like convex portion, and the connecting yarn is projected obliquely at the ridge-like convex portion, and has a trapezoidal shape in the cross section in the course direction (knitted fabric width direction) Therefore, no lateral displacement occurs with respect to the pressing force from above, and the narrow strip portion is wound inside the knitted fabric and has an elliptical shape in the cross section in the course direction, so that both air permeability and cushioning can be achieved. It is disclosed.

  In Patent Document 3, in a double raschel structure in which at least one side of the front and back is a warp structure, the structure of the warp part is composed of a chain knitting and an insertion knitting, and the chain knitting is supplied from at least two different sets of ridges. Knitting with two warps and knitting a chain knitting between adjacent warps. One warp warp forms the connecting structure with the right adjacent warp and the other warp with the left adjacent warp Thus, a double raschel fabric having a warp structure in which the stitch row of the warp portion does not converge in a string shape, the surface is flat, the appearance is good, and the ground yarn is not broken is disclosed.

  However, in Patent Document 1, since the connecting portion is formed of the same structure as the heel portion (band-shaped knitted fabric portion), the connecting portion becomes thick and mesh-like rather than warp-like. The problem that the design to be obtained is not obtained, and the connecting yarn is formed by overhanging, so that the connecting yarn is exposed between the ridges and the design is restricted, and the connecting yarn exposed by the protrusion is There is a problem that the so-called scratch resistance is deteriorated easily pulled out. In addition, since the heel part (strip-shaped knitted fabric part) is formed of a denbi knitted structure or a cord knitted structure, the heel part is tensioned and a heel part having a flat surface cannot be obtained. In some cases, only the apex of the buttocks is raised, and there is a problem that the buttocks cannot be raised uniformly.

  Regarding Patent Document 2, since the connecting thread is projected obliquely in the hook-shaped convex part and has a trapezoidal shape in the cross section in the course direction, the problem is that the connecting thread is exposed between the hook and the hook, and the design is restricted. Because there is a problem that the so-called scratch resistance is deteriorated, the connecting yarn exposed by is easily pulled out, and the heel part (band-like narrow part) is wound inside the knitted fabric and has an elliptical shape in the course direction cross section, For example, when brushing is performed, there is a problem that only the apex of the buttock is raised and the heel cannot be raised uniformly.

As for Patent Document 3, since the connecting structure is formed by moving the warp forming the buttock to the left and right, the structure forming the buttock is partially switched. There is a possibility that a step may be formed and the design properties may be affected, and the heel portion may be distorted by the tension caused by the warp moving left and right. In addition, when raising the hair, since the tissue forming the heel part is partially switched, the problem that the hair is not uniformly raised, and the connecting structure is formed by the warp of the heel part. There was a problem that not only the connecting structure part was raised.

Furthermore, by limiting the collar portion to a ground structure composed of a chain stitch row and an insertion yarn, it is possible to provide a collar-shaped double raschel fabric having a flat collar surface and good brushing properties.

  Hereinafter, the best mode for carrying out the present invention will be described in detail.

  FIG. 1 is a schematic configuration diagram of a double raschel knitting machine, and FIG. 2 is a schematic perspective view of a saddle-shaped double raschel fabric of the present invention. FIG. 3 is an explanatory diagram of a configuration form of a knitting stitch row and an insertion thread according to the present invention, FIGS. 4 (a) and 4 (b) are diagrams illustrating a tension by the insertion thread, and FIG. 5 is a scratch resistance. It is a figure explaining a measurement sample. FIG. 6 is an organization chart of Example 1, FIG. 7 is an organization chart of Example 4, and FIGS. 8 to 11 are explanatory diagrams of stitch rows and insertion yarns of the heel part of Examples 1 to 4. FIG. 12-14 is explanatory drawing of the stitch row and insertion yarn of Comparative Examples 1-3.

As shown in FIG. 2, the saddle-shaped double raschel fabric 10 of the present invention includes ground structures 1 and 2 that form two knitted fabrics on the front and back sides, and a connecting yarn 3 that connects them. A plurality of hooks 4 are formed on the side, and the insertion yarns 5 arranged at a ratio of one per hook part 4 at intervals according to the width of the hooks 4 are the width of the hooks 4. Are inserted into the ends of both sides of the collar portion 4 alternately at each end with a swinging width corresponding to the width and inserted so as to be folded back in the opposite direction. only bridged inserted ridge portions 4 of the two rows adjacent, and having a knitting engagement sealed portions in two rows of outer ends of the ridges 4 and 4 adjacent and.

  The saddle-shaped double raschel fabric 10 of the present invention has, for example, two front and rear needle rows aligned in the knitting machine width direction and spaced apart from each other as shown in FIG. Can be knitted using a double Russell machine having five ridges L1 to L5 above.

  For example, a knitting yarn A4 knitted on one of the front and back non-wrinkled ground structures 1 with a needle N1 using the knitting yarns A1 and A2 guided to the ridges L1 and L2 as a ground yarn and guided to the heels L4 and L5. , A5 is used as a ground yarn, and the other ground texture 2, that is, a so-called collar portion 4 that protrudes like a collar as described later, is knitted by the needle N2, and a knitted yarn guided to the collar L3. The yarns A3 are knitted into the fabrics 1 and 2 sequentially with the needles N1 and N2 as the connecting yarn 3, and the fabrics 1 and 2 are connected. In the figure, B1 to B5 are beams for supplying knitting yarn, G1 to G5 are guides for the ridges L1 to L5, and M1 and M2 are needle hooks.

  In knitting the cocoon-shaped double raschel fabric 10 of the present invention, the one non-cocoon-shaped ground structure 1 is knitted using the knitting yarns A1 and A2 guided to the ridges L1 and L2 as described above. The knitting structure of the ground structure 1 is not particularly limited, but from the viewpoint of strength and shape retention, a uniform and uniform structure with few irregularities and no large opening, for example, a plain structure such as a flat knitting is preferably used. It is done.

  As for the other ground texture (knot-shaped ground texture) 2, as shown in FIG. 3, a stitch row 7 in which the stitch loop 6 is continuously bound in the warp direction is formed using the knitting yarn A4 guided to the collar L4. In addition, the knitting yarn A5 guided by the heel L5 is used as a so-called insertion yarn 5 (hereinafter, referred to as an insertion yarn in the present invention) that is inserted in a horizontal direction without forming a stitch of the ground yarn. 4, a string of ridges formed by stitch rows 7 having the number of wells N, and threading appropriately at intervals according to the number of wells N of the stitch rows 7 forming the row of ridges 4. One stitch per 4 is arranged with 1 in and (N-1) out, and the stitch row at the end of the heel part 4 is alternated for each course with a predetermined swing width according to the width of the heel part 4 7 so that the knitting row 7 is folded back in the opposite direction so as to be knitted and locked. It allows to form a ridge-like foundation structure 2 constituting a row ridges 4 of the.

  At this time, in at least some of the courses, for example, as shown in the upper half of FIG. 3, the width of the insertion thread 5 arranged at a ratio of one row of the ridges 4 is set to the one row of ridges. 4 and having a swing width twice the number of wells N of the stitch row 7 that forms 4 (2N), it is bridged and inserted into two adjacent rows of collars 4, 4, and two adjacent rows of collars 4, 4 Knitted by folding back in opposite directions so as to alternately knitting and lock the stitch rows 7 and 7 at both outer end portions (end portions that are on the outer side when viewed from the bridging insertion portion).

  For example, in the case where the collar portion 4 is composed of a 4-well stitch row 7 as shown in FIG. 3, the insertion thread 5 is arranged 1-in and 3-out so as to be one for every 4 wells, as described above. Are inserted into two adjacent ridges 4 and 4 with a swinging width of 8 wells, which is twice the number of wells of the ridges 4, and knitted and locked to the stitch rows 7 at both outer ends of both ridges 4 and 4. Insert as you do. As shown in the lower half of FIG. 3, the insertion portion other than the above is knitted and locked alternately to the stitch rows 7 and 7 at both ends of the row of ridges 4 as shown in the lower half of FIG. Is inserted at the end.

  As a result, as shown in the right diagram of FIG. 3, the stitch row 7 of each heel portion 4 is bound by the tension of the insertion yarn 5 to form a so-called heel portion 4 having a shape that protrudes in a cocoon shape. The ground organization 2 is formed. In the figure, 5a represents a bridging insertion portion of the insertion yarn 5, and 5b represents a portion where the insertion yarn 5 is knitted and locked.

In the case of the knitting yarn A4 that is the ground yarn introduced to the heel L4, the stitch row 7 constituting the heel portion 4 is basically a chain knitting, and this is bound by the insertion yarn 5 to form a cocoon shape. Thread removal is unnecessary. In addition, in the case where the ground structure 2 that forms the collar part 4 is a ground structure that moves laterally, such as a denbi knitted structure, a cord knitted structure, etc., in order to separate the collar part 4 and the collar part 4 , It is necessary to remove the thread according to the number of needles moving sideways.

  As described above, the insertion yarns 5 are bridged and inserted into the two adjacent rows of collars 4, 4, whereby two rows of the insertion threads 5, 5 are adjacent to the two rows of collars 4. 4 will be folded and locked at both outer ends, and as a result, tension as shown by the arrows in FIG. 4 (a) will be applied to the stitch rows 7 forming the ridges 4 and 4, Therefore, the stitch row 7 of each heel part 4 is attracted and firmly bound as shown in the right figure of FIG. Since the ridges 4 are bound by the tension of the insertion yarn 5 in this way, the gaps between the stitch rows 7 forming the ridges 4 in each ridge 4 are reduced, and consequently the ridges have a flat surface with few irregularities. 4 can be formed, and a bowl-shaped double raschel land 10 as illustrated in FIG. 2 is obtained.

  On the other hand, as shown in FIG. 4 (b), if the insertion yarn 5 is simply inserted into the single heel part 4 while being knitted and locked so as to be folded back at the stitch row 7 at both ends. In this case, the tension due to the insertion yarn 5 is reduced, and the stitch row 7 forming the heel portion 4 cannot be sufficiently bound. Moreover, it is easy to shift | deviate to a horizontal direction and formation of the straight collar part 4 is difficult.

  As shown in FIG. 13, when a plurality of insertion yarns 5 are inserted into one collar portion 4, the tension generated when the insertion yarns 5 are knitted and locked to the collar portion 4 and folded back is offset. As a result, the stitch row 7 forming the heel portion 4 cannot be sufficiently bound. Further, when the swing width of the insertion yarn 5 is not an integral multiple of the number of wells N of the stitch row 7 forming the collar portion 4 as shown in FIG. 14, the insertion yarn 5 is formed at a portion other than the end portion of the collar portion 4. Will be folded and locked, and by the tension of the insertion yarn 5, the stitch row 7 forming the collar portion 4 will open the knitted and locked portion of the insertion yarn 5, and the collar portion 4 will be distorted. May be difficult to form the flange 4.

  As described above, when the insertion yarn 5 is inserted into the stitch row 7 that forms the collar portion 4, when inserted into two adjacent rows of collar portions 4, 4, both outer ends of each collar portion 4 are inserted. Part, that is, when the ribs 4 and 4 are inserted only into the row of stitches 7 and 7 at the end opposite to the inner end where they are close to each other, In order to bind the stitch rows 7 of the respective heel portions 4, it is necessary that the insertion yarn 5 is knitted and locked and inserted back into the stitch rows 7, 7 at both ends of 4. In addition, when it is inserted across three or more adjacent ridges, knitting becomes difficult depending on the number of wells of the stitch row 7 forming the ridge 4, which is not preferable in practice.

  In the double raschel site 10 of the present invention, the ratio of the bridging insertion portion 5a is preferably in the range of 20 to 100%, more preferably in the range of 20 to 70% (for example, FIGS. 8 to 10). When the ratio of the bridging insertion portion 5a is less than 20%, bridging between the two adjacent ridge portions 4 and 4 decreases, and the ridge portion 4 may be shifted in the course direction (knitting fabric width direction).

The ratio of the bridging insertion portion 5a in the present invention is obtained by the following formula. Further, FIG. 3 shows the number (the number of courses) A in which the insertion yarn 5 is bridged and inserted into two adjacent rows of flanges 4 and 4 in the repeating unit, and the number of courses B in the repeating unit.
Ratio of bridge insertion part (%) = A / B x 100
A: Number of portions where the insertion thread is bridged and inserted into two adjacent ridges in the repeating unit B: Number of courses in the repeating unit

  The stitch row 7 forming the heel part 4 of the present invention is not particularly limited, and a stitch row made of a conventionally known knitting structure such as a chain knitting structure, a denby knitting structure, or a cord knitting structure may be used depending on its purpose and application. It can be selected as appropriate. For example, when raising the ridge-like double raschel fabric 10, the stitch row 7 and the insertion yarn 5 made of a chain stitch structure are formed from the viewpoint that the surface of the heel portion 4 is formed flat and the raising can be performed uniformly. It is preferable to form the collar part 4 by a combination.

  Further, when the collar portion 4 is formed by the combination of the stitch row 7 made of a chain stitch structure and the insertion yarn 5, as shown in the knitting structure of FIG. 7 and the explanatory view of FIG. In the knitting of the structure 2, the insertion position of the insertion yarn 5 that is arranged at a ratio of one heel portion with respect to the stitch row 7 of the chain stitch is inserted in the well direction (knitting direction). ) At an appropriate interval (appropriately the number of courses), for example, by moving in the course direction (the knitted fabric width direction) by 1/2 N wells of the number of wells N of the stitch row 7 forming the collar 4. By changing the stitch row 7 bound with five yarns, it is also possible to form a hook-shaped double raschel fabric 10 in which the hook portion 4 has a checkered pattern as shown in FIG.

  The number of wells N of the set of stitch rows 7 forming the collar 4 of the present invention is preferably in the range of 2 to 10 wells, more preferably in the range of 3 to 7 wells. When the number of wells N in the stitch row 7 is less than 2 wells, it is difficult to form the collar portion 4 and the intended design may not be obtained. When the number N of wells of the stitch row 7 exceeds 10 wells, the tension due to the insertion thread 5 is small with respect to the stitch row, and the stitch row 7 forming the collar portion 4 cannot be sufficiently bound, and the stitch row of the collar portion 4 There is a possibility that the gap 4 of 7 becomes large or the surface does not become flat, and the collar portion 4 is distorted.

  In the cocoon-shaped double raschel fabric 10 of the present invention shown in FIG. 2 obtained as described above, the insertion thread 5 is bridged and inserted into adjacent two rows of ridges 4 and 4 at an appropriate interval. Since the portions 4 and 4 are bridged with each other by the insertion thread 5, the shift of the heel portion 4 with respect to the course direction (knitted fabric width direction) is prevented, and the straight heel portion 4 can be formed.

  Further, in the saddle-shaped double raschel fabric 10 of the present invention, the insertion yarn 5 is positioned at the lower portion (the connecting yarn 3 side) with respect to the stitch row 7 forming the collar portion 4. In the case where the design of No. 4 is not affected and the hook-shaped double raschel fabric 10 is raised, it is possible to raise only the stitch row forming the collar portion 4.

  Further, for example, even when a load is applied to the hook-shaped double raschel ground 10 in the vertical direction and the connecting yarn 3 is bent and is likely to protrude from between the hook portions 4 and 4, the bridging insertion portion 5a of the insertion yarn 5 is inserted. Since the protrusion of the connecting yarn 3 is prevented by this, the scratch resistance is good.

  Further, as described above, the bridging insertion portion 5a of the insertion yarn 5 can prevent the collar portion 4 from being displaced with respect to the course direction (the knitted fabric width direction). Therefore, the connecting yarn 3 of the collar-shaped double raschel fabric 10 of the present invention. Can connect the hook-shaped ground structure 2 and the non-hook-shaped ground structure 1 orthogonally. Thereby, it is possible to provide the hook-shaped double russell fabric 10 excellent in the design property in which the connecting yarn 3 is not exposed between the hook part 4 and the hook part 4.

  The material of the fiber used in the present invention is not particularly limited, and conventionally known fibers such as natural fibers, regenerated fibers, semi-synthetic fibers, and synthetic fibers can be appropriately selected according to the use. Synthetic fibers are preferred for reasons of excellent physical properties, and polyester is more preferred.

  The form of the yarn used in the present invention is not particularly limited, and a conventionally known form of yarn such as spun yarn, multifilament yarn, monofilament yarn, and processed yarn can be appropriately selected depending on the application. is there. Especially, as a thread | yarn which forms a collar part, a multifilament thread | yarn is preferable from the reason that it is excellent in raising property, and the multifilament thread | yarn processed by the bulky process is more preferable. On the other hand, as the connecting yarn, a monofilament yarn is preferable because of its excellent shape retention.

  Although the fineness of the yarn used in the present invention is not particularly limited, it is preferably 33 to 440 dtex. If the fineness of the yarn is less than 33 dtex, the physical properties of the double raschel fabric may not be satisfied. When the fineness of the yarn exceeds 440 dtex, there is a possibility that knitting may become difficult and the texture and touch of the double raschel fabric may be impaired.

  Further, the single yarn fineness when the yarn is a multifilament yarn is not particularly limited, but is preferably 0.5 to 3 dtex. If the single yarn fineness is less than 0.5 dtex, the physical properties of the double raschel fabric may not be satisfied. If the single yarn fineness exceeds 3 dtex, there is a risk that the texture, feel and raising of the double raschel fabric may be impaired.
