SUMMARY OF THE INVENTION

PROBLEM

In the knitting yarn fixing method of Patent Document 1, the yarn guide needs to be knocked back several times, and the stitches must be transferred several times between the setbacks. Thus, if there are a large number of fixing portions of a knitting yarn in a knit fabric, the time until completion of the knitting becomes long. In recent years, a rapid provision of a knitwear while diversifying the customer's needs is increasingly demanded, so that there is a need for a method of efficiently fixing the knitting yarn in the basic mesh row.

The present invention relates to the above-described situation, and it is an object of the present invention to provide a method of fixing a knitting thread which can efficiently fix the knitting thread in the base mesh row.

TROUBLESHOOTING

• [Prozess I] Kontinuierliches Stricken eines Paars von Haltemaschen in Bezug auf ein Paar von spezifischen Maschen, die ein Teil der Basismaschenreihe sind und nebeneinander in einer Strickbreitenrichtung angeordnet sind, unter Verwendung des Strickfadens, und Bilden einer Verbreiterungsmasche auf einer leeren Nadel in Nachbarschaft zu den spezifischen Maschen.
• [Prozess II] Überlappen der Haltemaschen, um eine doppelte Masche zu bilden, und Umhängen der Verbreiterungsmasche zu einer Position zum Füllen eines in der Basismaschenreihe während eines Durchlaufs zum Bilden der doppelten Masche gebildeten Lochs.

A method for fixing a knitting yarn of the present invention is a method of fixing a knitting yarn in a flat knitting machine having a needle bed and another needle bed disposed opposite to each other in a front-rear direction, the method comprising feeding a knitting yarn to the needle beds from a state where a base mesh row is held on the one needle bed and fixing the knitting yarn in the base mesh row, and further includes the following processes.

• [Process I] Continuously knitting a pair of holding stitches with respect to a pair of specific stitches which are a part of the base mesh row and arranged side by side in a knitting width direction, using the knitting yarn, and forming a widening stitch on an empty needle adjacent to specific stitches.
• [Process II] Overlapping the holding stitches to form a double stitch, and hanging the widening stitch to a position to fill a hole formed in the base stitch row during one pass to form the double stitch.
• [Process III] Knitting a new base mesh row with fixation meshes therein following the wale direction of the double mesh and the widening mesh.

The widening mesh is provided to fill a hole formed in the base mesh row during the formation of the double mesh, and thus is formed at a position not far from the specific meshes. The position for forming the widening mesh is preferably a position not more than three stitches away in the knitting width direction, and can be determined by those skilled in the art in consideration of the thickness of the knitting yarn, the type of the flat knitting machine, the state of formation of the knitted fabric and so on.

According to one aspect of the method of fixing the knitting yarn of the present invention, one of the pair of holding stitches is a left-hand stitch and the other stitch is a right-hand stitch.

According to another aspect of the method for fixing the knitting yarn according to the present invention, the broadening stitch is formed by performing split knitting on one of the pair of specific stitches. Here, the split knitting is a knitting operation in which a stitch P held on the knitting needle X is transferred to a knitting needle Y opposite the knitting needle X, and a new stitch Q is formed which is pulled out of the stitch P on the knitting needle X (see FIG eg the Japanese Patent Publication No. 2604653 etc.). In this case, the loop P transferred to the knitting needle Y becomes the broadening stitch.

According to another aspect of the method of fixing the knitting yarn of the present invention, the knitting yarn can be fixed to a plurality of different fixing portions in a knitting width direction of the basic mesh row. In this case, all the knitting operations of the process I are performed in the same knitting pass with respect to all the fixing areas, and all the knitting operations of the process II are performed in the same knitting pass with respect to all the fixing areas. The knitting processes of the process I are knitting the pair of holding stitches and knitting the broadening stitch. The knitting processes of the process II are the wrapping for forming the double stitch and the wrapping of the widening mesh.

According to another aspect of the method for fixing the knitting thread of the present invention, a shrinkable thread may be used as the base knitting thread for the base mesh row or as the knitting thread. The shrinkable thread includes a heat-shrinkable thread, an elastic thread or the like.

EFFECTS OF THE INVENTION

In the method of fixing the knitting thread of the present invention, the knitting thread can be firmly fixed in the base mesh row by simply knitting a pair of retaining stitches, overlapping the retaining stitches, and knitting a new stitch on the double stitch, thereby improving the knitting efficiency as compared to the prior art Prior art is improved. Furthermore, in the method for fixing the knitting yarn of the present invention, the hole formed by forming the double stitch in fixing the knitting yarn can be filled, thereby preventing the hole in the fabric from being visible.

By knitting the retaining stitches as a right-hand stitch and a left-hand stitch, the length of a cross-over thread connecting the retaining stitches can be made longer than if the retaining stitches are knitted only as right-hand stitches or as left-hand stitches, causing the thread to break when the retaining stitches are transferred can be suppressed for forming the double mesh in the process II. And if, as in 2 For the embodiment described below, where the cross stitching thread connecting the holding stitches is long in the process of deforming the retaining stitches and entangling the basic strip row knitting yarn, the retaining stitches can easily be deformed and the knitting yarn can be easily entangled with the base mesh string.

Because the widening mesh is formed simultaneously with the knitting of the retaining stitches by performing the split-knitting for forming the widening mesh, the knitting efficiency of the knitted fabric can be improved.

In the conventional process for fixing the knitting yarn, when a plurality of fixing portions of the knitting yarn are provided in a basic pile row, first, one of the fixing portions must be processed, and then the other fixing portions are successively processed. On the other hand, in the method of fixing the knitted fabric of the present invention, the processing of all the fixation areas can be performed simultaneously. Thus, in the method for fixing the knitting thread of the present invention, the knitting thread can be fixed much more efficiently in the base stitch row than in the conventional method for fixing the knitting thread.

An innovative three-dimensional knit can be knitted by using a shrinkable thread as the base knitting thread or the knitting thread to be fixed in the base stitch row. For example, if the base mesh row is configured with the shrinkable thread, a knit with a looped knitting thread as in FIG 4 (A) knit shown. When an insert thread for making an inserting knitting is formed by the shrinkable thread, a pleated three-dimensional knitted fabric as in FIG 4 (B) knit shown.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

<First Embodiment>

For forming a pattern in a knit fabric, there is known an inserting knit in which stitches of a base stitch row of the knit fabric are assigned to front and back needle beds, and a knitting thread (inlay yarn) different from a base knit base knit yarn is inserted between the assigned stitches ( eg from the unaudited Japanese Patent Publication No. 2007-277738 ). In the insertion knitting, the pattern is formed by an exposed part where the lay-in thread is exposed to an area of the base mesh row. However, in a tubular knit such as a sweater, it is difficult to form the pattern with the insertion knitting. Because the suture is merely interposed between the stitches of the base mesh row, the suture may be able to disengage from the base mesh row in a chain reaction as a single area of the suture thread breaks. In order to eliminate this problem, both ends of the exposed portion may be individually fixed in the base mesh row, but a considerable time is required for fixing the large number of exposed portions with the conventional method for fixing the knitting thread. Thus, an efficiency in fixing the exposed portion is realized by fixing the exposed portion of the laying yarn by the method of fixing the knitting yarn of the present invention. An example of the method for fixing the knitting thread of the present invention will be described below with reference to the knitting process diagram of FIG 1 described.

In this embodiment, a four-bed flat knitting machine is used which includes a lower front needle bed (hereinafter referred to as FD) and a lower rear needle bed (hereinafter referred to as BD) extending in a transverse direction and opposite each other in a front-rear position. Direction, and an upper front needle bed (hereinafter referred to as FU) and an upper rear needle bed (hereinafter referred to as BU) which are respectively disposed above the FD and the BD and in which a large number of knitting needles are arranged in a row are arranged at the same distance as in the lower needle beds includes. In the flat knitting machine, stitches can be transferred between the front and back needle beds, and the BD and BU arranged in the flat knitting machine can be displaced left and right.

"S + number" in the left column of 1 indicates the number of the knitting process, and the right column indicates a knitting state of the needle bed in each knitting process. Uppercase letters in the right column indicate the positions of the knitting needles, and the arrow indicates the direction of the transfer. A pentagonal marker indicates a thread guide 80 which feeds a base yarn Y8, and a yarn guide 90 feeding a Y9 inlay yarn on.

In S1, from a state in which a front side knit part and a back side knit part of a tubular knit are held on the knitting needles A to L of the FD and the knitting needles A to L of the BD, respectively, the yarn guide 80 , which feeds the base knitting yarn, moves to the right side in the drawing plane to a base stitch row 10 Knitting (back side knitted part). The stitches of the knitting needles C, D (I, J) of the BD in the base stitch row 10 are specific meshes 1 . 2 in the method for fixing the knitting thread of the present invention and are adjacent in a knitting width direction.

In S2, the thread guide 80 is moved to the left to knit a row of the front side knitting part, and the stitches of the knitting needles C, F, G, H, I, L of the BD are transferred to the knitting needles C, F, G, H, I, L of the FU , Such stitching of meshes is a preparation for arranging and fixing the laying yarn Y9 (see S3) in the base mesh row 10 , The purpose of the specific mesh transferring 1 consists of a left-hand stitch (see the retaining flap 3 from S3) in the weft direction of the specific mesh 1 to knit. The wrapping of the specific mesh 1 is not required if the retaining mesh 3 to knit as a right-hand stitch.

In S3, the thread guide 90 , which feeds the inlay thread Y9, moves to the right to the held loop 3 knitting at the knitting needle C (I) of the FU, and split knitting is performed with the knitting needle D (J) of the BD (in accordance with the process I of the present invention). A state in which the specific stitch held on the knitting needle D (J) of the BD in S2 2 to the knitting needle D (J) of the FU is hung, and one of the specific mesh 2 pulled out retaining flap 4 , which is a new loop held on the knitting needle D (J) of the BD, is obtained by performing the split knitting with the knitting needle D (J) of the BD. The retaining stitches 3 . 4 are a pair of stitches that are continuous by a movement of the thread guide 90 be knitted, with the retaining mesh 3 and the retaining pocket 4 be connected directly by means of a sinker handle. The specific loop transferred to the FU by split-knitting 2 becomes as a broadening mesh in a following process 5 used. That is, in S3, the knitting of the pair of retaining tabs 3 . 4 and knitting the broadening mesh 5 in the same knitting pass with respect to all of the plurality of fixing stitches.

Here, the widening mesh 5 be formed by the split-knitting on the specific stitch 1 is carried out. The broadening mesh 5 may be a picking stitch formed on an empty needle. For example, a gripping mesh (broadening mesh 5 ) at the knitting needle D (J) of the FU against the specific stitch 2 of S2 or the adjacent knitting needle E (K) are formed. Alternatively, the gripping mesh (broadening mesh) 5 at the knitting needle C (I) of the BD against the specific stitch 1 of S2, the knitting needle B of the FU (knitting needle H of the BD) or the like are formed.

In S4, the broadening mesh held on the knitting needle D (J) of the FU becomes 5 to the knitting needle C (I) of the BD in the same knitting process (part of the process II). This hanger is an operation performed to reduce the number of stitches in the knitting width direction of the basic mesh row 10 during the formation of the double mesh 7 to fill in the hole formed in the next step S5. This means that in S4 the widening mesh 5 is transferred to the knitting needle C (I) of the BD containing an empty needle in the row to form the double stitch 7 within the knitting needles C, D (I, J) of the BD at which the specific stitches 1 . 2 to be held in S1 will.

In S5, the holding stitch formed on the knitting needle C (I) of the FU in the course of split-knitting becomes S3 3 and the retaining stitch formed on the knitting needle D (J) of the BD 4 overlapped with each other to the double stitch 7 to form at the knitting needle D (J) of the BD in the same knitting pass (a part of process II).

In S6, the stitches of the knitting needles F, G, H and L of the FU are transferred to the knitting needles F, G, H and L of the BD. A state in which the insertion yarn Y9 intervenes between the stitches of the base mesh row 10 is inserted is obtained in S6.

In S7, the thread guide 80 moved to the right to get a new base mesh row 11 Knitting at the knitting needles A to L of the BD (corresponds to the process III of the present invention). The base mesh row 11 contains fixation meshes 8th . 9 , the double-mesh wale direction 7 and the broadening mesh 5 follow in S6, where the in the base stitch row 10 arranged Einlegefaden through the base mesh row 11 is fixed.

In the knitting process described above, the formation of the holding stitches 3 . 4 and the broadening mesh 5 at two fixing portions of the loading yarn Y9 in the same knitting pass as shown in S3. The wrapping of the widening mesh 5 in both fixation areas is performed in the same knitting pass as shown in S4, and the wrapping of the retaining flap 3 for making double stitch 7 at both fixation areas is performed in the same knitting pass as shown in S5. In the above-described knitting configuration, therefore, the insert yarn Y9 in the basic mesh row can be used 10 be fixed more efficiently than in the conventional configuration in which the knitting yarn is sequentially fixed to each fixation region.

When the inlay yarn Y9 is placed in the front side knit part held on the FD after S7, knitting is to be performed similarly as in S1 to S7 using the FD and the BU, the FD serving as the one needle bed of the present invention. When the inlay yarn Y9 is in the base mesh row 11 are arranged and fixed, S2 to perform S6, where the base mesh row 11 as the base mesh row 10 of S1 serves.

Hereinafter, a mechanism for strongly fixing the laying yarn Y9 in the base mesh row will be described 10 by performing the knitting process described above based on the loop diagrams of FIG 2 described. The loop diagrams of 2 show that on the BD of S7 in 1 held back side knitted part from the outside of the hose knit and a temporal change of the stitches in the back side knitting part of 2 (A) to 2 (D) ,

If the insertion thread Y9 from the in 2 (A) shown state is pulled to the left and right, the retaining tabs 3 . 4 deformed to like in 2 B) and 2 (C) to be shown united. The retaining stitches 3 . 4 are overlapped with each other to make a double stitch 7 to become, and be through one on the double stitch 7 following fixation mesh 8th fixed so that the retaining tabs 3 . 4 can not be unified, and the insertion thread Y9 is around the trunk (position of the platinum handle) of the fixing mesh 8th wound. Furthermore, in the deformation of the retaining tabs 3 . 4 the specific mesh 1 in one of the fixation mesh 8th deforming direction and is the inlay Y9 in the base mesh row 10 fixed.

As in 2 (D) is shown, the widening mesh 5 at a position for filling the hole of the base mesh row 10 arranged so that through the widening mesh 5 prevents a hole in the fabric is visible.

A knit such as a sweater with an inlay pattern like in 3 (A) can be knitted, for example, by using the above-described method for fixing the knitting thread. The pattern of 3 (A) forming white part is the exposed part where the inlay thread is exposed to the front of the knit (the part across to the knitting needles E to I of the BD in S6 of FIG 1 , etc.). Both ends of each exposed part are securely fixed by the above-described method for fixing the strands, so that even if a single exposed part breaks, the other exposed parts will not be affected and thus the insert thread will not be pulled out of the base mesh. Using the Einlegefadens so a hose knit can be provided with different patterns.

Thanks to the configuration for individually fixing the exposed part of the laying thread, the exposed part can be intentionally cut. In this way, as in 3 (B) a knitted fabric can be obtained in which the inlay thread (the white part) is raised. Such a knit fabric can be produced because the lay-in thread does not come off the base stitch row even if the exposed part is cut because both ends of the exposed part are securely fixed in the base stitch row.

And, by knitting the base mesh string with a heat-shrinkable thread and using a non-heat-shrinkable thread as the laid-in thread, when thermal processing is performed on the finished fabric, the non-shrunken inserting yarn protrudes outward to a pile shape when the base-mesh row is shrunk. As a result, as in 4 (A) shown a knitted part can be produced with an exposed part formed into a pile mold (see the curved, black part).

And, by knitting the base mesh row with a non-heat-shrinkable thread and using a heat-shrinkable thread as the laid-in thread, when carrying out thermal processing on the finished fabric, the base mesh row is pulled away from the laid-in thread as the lay-up thread is shrunk. In this way, as in 4 (B) shown a three-dimensional knitted fabric with fold-like elevations are generated.

<Variation>

Instead of the knit yarn Y9 between the right and left stitches of the base stitch row as in the first embodiment 10 The knitting yarn Y9 may be inserted along one surface side or the other surface side of the base mesh row 10 can be designed and the knitting yarn Y9 then at a plurality of fixing areas in the base mesh row 10 be fixed. For example, the whole knitting yarn Y9 is arranged on the inside of the hose knit by performing knitting similar to S3 to S5 to knit the yarn Y9 without transferring the stitches of the knitting needles F, G, H, L in S2 of FIG 1 to fix. A tubular knit in which an elongation in the knitting width direction is suppressed by the knitting yarn Y9 is realized by using a knitting yarn less prone to stretch than the knitting yarn Y9.

<Second Embodiment>

The method of fixing the knitting yarn of the first embodiment may also be used to prevent the yarn from being severed during yarn introduction and yarn feeding. For example, when knitting a sweater having a horizontal stripe pattern, another knit part is knit following the wale direction of the knit part knitted with a first knitting thread, and the other knit part is knitted with a second knitting thread of a different color from the first knitting thread. In this case, the threading of the first knitting thread and the thread insertion of the second knitting thread are performed. The method of fixing the knitting yarn of the first embodiment may be used to fix the redundant ends of the knitting yarns so that the redundant ends can be securely fixed. In addition, the method for fixing the knitting yarn of the First embodiment also be used to fix the knitting thread of an Intarsia pattern.
