Description

The present invention relates to a method for knitting pile fabric.

Conventionally, methods for knitting pile fabrics with multiple pile loops have been known. Patent Document 1 discloses a method for knitting pile fabrics using a flat knitting machine equipped with a pile sinker for forming pile loops. Patent Document 2 discloses a method for knitting pile fabrics using a flat knitting machine equipped with a compound needle. A compound needle is a knitting needle that has a needle body with a hook and a slider that opens and closes the hook. In addition, methods for knitting pile fabrics using a general-purpose flat knitting machine that does not have special components such as a pile sinker or compound needle are known.

In the method for knitting a pile fabric, a first pile stitch row and a first fixed stitch row are knitted in the wale direction following the first stitch row held on the needle bed. The first pile stitch row has a plurality of pile loops and a plurality of anchor stitches that sandwich each pile loop. The first fixed stitch row has a plurality of fixed stitches that fix each anchor stitch.

As an example, a method of knitting a pile fabric using compound needles will be described based on the knitting process diagram in Figure 4. The "T + number" in the left column of Figure 4 indicates the knitting process number. The right column shows the knitting state of stitches on the front needle bed FB and the back needle bed BB. The vertical bars in the right column indicate the needle body of the compound needle, and the horizontal bars indicate the slider. The slider is only shown in the process in which it is used. The drop-shaped marks indicate the stitches of the first stitch row that are held on the back needle bed BB at the start of knitting as shown in T0, the Ω-shaped marks and V-shaped marks indicate the stitches of the first pile stitch row 3, and the Π-shaped marks indicate the stitches of the first fixed stitch row 5.

T0 in FIG. 4 shows the state in which the first stitch row 1 is held on the needle body of the compound needle on the back needle bed BB. From this state, at T1, a first fixed stitch row 5 consisting of a plurality of fixed stitches 50 is knitted. The fixed stitches 50 are held by the hooks of the needle body, and the stitches of the first stitch row 1 are held on the slider of the compound needle.

In T2, the first pile stitch row 3 is knitted. The first pile stitch row 3 has a plurality of pile loops 31 and a plurality of anchor stitches 30. The pile loops 31 are hook stitches formed on the needle body of the FB. The anchor stitches 30 are tuck stitches overlapped on the fixed stitches 50. By this T2, the overlapping stitches consisting of the anchor stitches 30 and the fixed stitches 50 are pulled out from the stitches of the first stitch row 1 and are held by the hook. As a result, the anchor stitches 30 are fixed by the fixed stitches 50.

In T3, the pile loop 31 is removed from the hook of the compound needle of the front needle bed FB. When forming the pile fabric portion in the wale direction, the double stitches held by the compound needle of the back needle bed BB are regarded as the first stitch row 1, and T1 and T2 are repeated.

Although we will not go into detail here, in a method of knitting a pile fabric using a pile sinker, the first pile stitch row and the first fixed stitch row are knitted simultaneously. In addition, in a method of knitting a pile fabric using a general-purpose machine, the first pile stitch row is knitted and then the first fixed stitch row is knitted.

Special Publication No. 61-20668 Japanese Patent Application Publication No. 11-81101

In some cases, a pile fabric is knitted in a cylindrical or C-shape on a needle bed. In this case, in addition to the first stitch row, a second pile stitch row is knitted on a needle bed opposite to the needle bed on which the first pile stitch row is anchored. A knitting yarn connecting the end stitch of the first pile stitch row and the start stitch of the second pile stitch row crosses between the two opposing needle beds. As described with reference to FIG. 4, to form a pile loop, two anchor stitches are required to sandwich the pile loop in the knitting width direction. Therefore, a pile loop cannot be formed between the end stitch of the first pile stitch row and the start stitch of the second pile stitch row. Therefore, in a pile fabric in which the first pile stitch row and the second pile stitch row are connected in a cylindrical or C-shape on the needle bed, there is a portion where there is no pile loop at the boundary between the first pile stitch row and the second pile stitch row.

One of the objects of the present invention is to provide a method for knitting a pile fabric that can form pile loops at the boundary between a first pile stitch row and a second pile stitch row that are connected in a cylindrical or C-shape.

<1> The method for knitting the pile knitted fabric of the present invention comprises:
Using a flat knitting machine having a front needle bed and a back needle bed opposed to each other,
From a state in which the first stitch row and the second stitch row are held on one of the front needle bed and the other of the back needle bed,
A first pile stitch row and a first fixed stitch row are knitted in the wale direction following the first stitch row;
A second pile stitch row and a second fixed stitch row are knitted in the wale direction following the second stitch row;
the first pile stitch row and the second pile stitch row each include a plurality of standard pile loops and a plurality of anchor stitches sandwiching each of the standard pile loops;
In a method for knitting a pile fabric, the first fixed stitch row and the second fixed stitch row include fixed stitches that fix each anchor stitch,
After knitting the first pile stitch row and before knitting the second pile stitch row, an end pile loop arranged on the outer side of the end stitch in the knitting width direction and an additional stitch arranged on the outer side of the end pile loop in the knitting width direction are knitted;
After knitting the first fixed stitch row or the second fixed stitch row including a first fixed stitch for fixing the end stitch and a second fixed stitch for fixing the additional stitch, the end pile loop is released and the second fixed stitch is overlapped on the first fixed stitch;
The end stitch is a terminal stitch of the first pile stitch row or a starting stitch of the second pile stitch row.

<2> As one embodiment of the knitting method of the pile knitted fabric of the present invention,
the first stitch row and the second stitch row are shifted in a knitting width direction to form a non-overlapping region in which the first stitch row and the second stitch row do not overlap in the knitting width direction in either the front needle bed or the rear needle bed;
The additional stitches may be formed in the non-overlapping region.

<3> As one embodiment of the knitting method of the pile knitted fabric of the present invention,
forming one of two anchor stitches sandwiching each standard pile loop of the first pile stitch row by a tuck;
forming one of two anchor stitches sandwiching each standard pile loop of the second pile stitch row by a tuck;
One of the anchor stitches and the additional stitches sandwiching the end pile loop may be formed by a tuck.

In the knitting method of the pile knit fabric of the present invention, an end pile loop and an additional stitch are knitted on the outer side in the knitting width direction of the end stitch located at the boundary between the first stitch row and the second stitch row. In this case, the end stitch and the additional stitch function as anchor stitches that maintain the end pile loop. Therefore, according to the knitting method of the pile knit fabric of the present invention, an end pile loop can be formed at the boundary between the first stitch row and the second stitch row.

In the knitting method of the pile knit fabric of the present invention, additional stitches are formed to form end pile loops, but the knitting width of the pile knit fabric does not change due to the additional stitches. This is because the first fixed stitch and the second fixed stitch that fix the additional stitch and the end stitch, respectively, are formed, and then the first fixed stitch and the second fixed stitch are overlapped.

According to the knitting method of the above embodiment <2>, the appearance of the standard pile loops and the end pile loops can be made to be almost the same, as shown in the embodiment 1 described below.

According to the knitting method of the above embodiment <3>, the intervals between the pile loops arranged in the wale direction are narrowed, so that a pile knit fabric with dense pile loops can be knitted.

FIG. 1 is a diagram showing a first knitting step of a knitting method for a pile fabric according to a first embodiment. FIG. 2 is a second knitting process diagram following FIG. FIG. 3 is a third knitting process diagram following FIG. FIG. 4 is a knitting process diagram showing an example of a conventional method for knitting a pile fabric.

The method for knitting the pile fabric according to the embodiment will be explained below with reference to the drawings.

<Embodiment 1>
In this embodiment, an example of a method for knitting a pile fabric using a general-purpose two-bed flat knitting machine will be described based on the knitting process diagrams of Figures 1 to 3. In the left column of Figures 1 to 3, "S + number" indicates the number of the knitting process. In the right column, the knitting state of the stitches in each knitting process is shown. In the right column, black dots indicate knitting needles, circle marks indicate knit stitches, V marks indicate hanging stitches, square marks indicate tuck stitches, and inverted triangle marks indicate yarn feeder 9. Arrows indicate stitch transfer. Knitting operations performed in each knitting process are shown in thick lines.

S1 in Figure 1 shows the state in which a first stitch row 1 is knitted on the front needle bed FB using the yarn feeder 9, and a second stitch row 2 is knitted on the back needle bed BB.

In S2, the second stitch row 2 is shifted to the left relative to the first stitch row 1. As a result, a non-overlapping region R1 is formed in the front needle bed FB, where the first stitch row 1 and the second stitch row 2 do not overlap in the knitting width direction. To achieve the S2 state, for example, the rear needle bed BB may be racked to the left.

In S3, the front needle bed FB and the rear needle bed BB are shifted, the yarn feeder 9 is moved leftward, and the first pile stitch row 3 is knitted. The first pile stitch row 3 is knitted in the following order: anchor stitch 30 consisting of knit stitches, standard pile loop 31, and anchor stitch 30 consisting of tuck stitches. The end stitch 3E of the first pile stitch row 3 is an anchor stitch consisting of knit stitches. Here, the end stitch 3E is referred to as the end stitch 7.

In S3, an end pile loop 71, an additional stitch 70, and a turned stitch 72 are knitted further outward in the knitting width direction than the end stitch 7. The end pile loop 71 is a pick-up stitch formed on an empty needle of the back needle bed BB. The additional stitch 70 is a pick-up stitch formed on an empty needle of the front needle bed FB. The additional stitch 70 is positioned further outward in the knitting width direction than the end pile loop 71. The turned stitch 72 is a pick-up stitch formed on an empty needle of the front needle bed FB. The turned stitch 72 is positioned further outward in the knitting width direction than the additional stitch 70. The turned stitch 72 is intended to make it easier to knit the additional stitch 70, and is not an essential stitch.

In S3, the standard pile loop 31 and the end pile loop 71 are knitted while the yarn feeder 9 moves to the left. The distance between the two adjacent standard pile loops 31 is equal to the distance between the end pile loop 71 and the standard pile loop 31, and the distance between the two anchor stitches 30 sandwiching the standard pile loop 31 is equal to the distance between the end stitch 7 and the additional stitch 70 sandwiching the end pile loop 71. Therefore, the standard pile loop 31 and the end pile loop 71 are knitted under almost the same conditions, so that the appearance of all the pile loops 31, 71 including the end pile loop 71 is almost the same. A pile knitted fabric including such standard pile loops 31, 71 has an excellent appearance. The end pile loop 71 and the additional stitch 70 can be positioned in the above-mentioned position because the positions of the ends of the first stitch row 1 and the second stitch row 2 are shifted left and right in S2 to form a non-overlapping region R1 on the front needle bed FB.

In S4, the yarn feeder 9 is moved to the right to knit the second pile stitch row 4. The second pile stitch row 4 is knitted in the order of anchor stitches 40 made of knit stitches, standard pile loops 41, and anchor stitches 40 made of tuck stitches. The start stitch 4S and end stitch 4E of the second pile stitch row 4 are anchor stitches made of knit stitches.

When the knitting of Figs. 1 to 3 is repeated, knitting of S3 of Fig. 1 is performed after S13 of Fig. 3. In that case, the second pile stitch row 4 of S4 of Fig. 1 can be regarded as the first pile stitch row, and the pile stitch row knitted in the second S3 can be regarded as the second pile stitch row. Therefore, in S4, like S3, an end pile loop 71, an additional stitch 70, and a turned-up stitch 72 are knitted on the outside in the knitting width direction of the end stitch 4E of the second pile stitch row 4. The end pile loop 71 is a pick-up stitch formed on an empty needle of the front needle bed FB, and the additional stitch 70 and the turned-up stitch 72 are pick-up stitches formed on an empty needle of the back needle bed BB. The turned-up stitch 72 is not essential.

In S5, the yarn feeder 9 is moved leftward to knit the first fixed stitch row 5. The first fixed stitch row 5 includes fixed stitches 50 that follow each anchor stitch 30 in the wale direction in S3. The fixed stitches 50 fix the anchor stitches 30. Here, the fixed stitches 50 that follow the end stitches 7 of the first pile stitch row 3 in the wale direction are referred to as first fixed stitches 8.

In S5, a second fixed stitch 80 and a third fixed stitch 82, which are part of the first fixed stitch row 5, are further knitted. The second fixed stitch 80 is a tuck stitch that overlaps the additional stitch 70 (front needle bed FB of S4). The third fixed stitch 82 is a knit stitch that continues in the wale direction from the turned-back stitch 72 (front needle bed FB of S4).

In S6, the yarn feeder 9 is moved to the right to knit the second fixed stitch row 6. The second fixed stitch row 6 includes fixed stitches 60 that follow each anchor stitch 40 in the wale direction in S4. The fixed stitches 60 fix the anchor stitches 40. The fixed stitches 60 that follow the end stitches 7 of the second pile stitch row 4 in the wale direction are specifically referred to as first fixed stitches 8.

In S6, the second fixed stitch 80 and the third fixed stitch 82, which are part of the second fixed stitch row 6, are knitted. The second fixed stitch 80 is a tuck stitch that overlaps the additional stitch 70 (rear needle bed BB of S4). The third fixed stitch 82 is a knit stitch that continues in the wale direction from the turned stitch 72 (rear needle bed BB of S4).

In S7 of FIG. 2, the yarn feeder 9 is moved leftward, and a new first fixed stitch row 5 is knitted in the wale direction following the first fixed stitch row 5 knitted in S5. All the stitches in the new first fixed stitch row 5 are knit stitches. The new first fixed stitch row 5 is not essential, but is intended to make it easier to transfer stitches in that knitting course by eliminating tuck stitches from the front needle bed FB. Here, the third fixed stitch 82 of the new first fixed stitch row 5 is a twisted stitch knitted in the opposite direction to the other stitches in the first fixed stitch row 5.

In S8, the end pile loop 71 is removed from the knitting needles of the back needle bed BB. The end pile loop 71 is no longer engaged with the knitting needles. In the following S9, the second fixed stitch 80 of S8 is overlapped on the first fixed stitch 8 to form an overlapped stitch 85.

In S10, the yarn feeder 9 is moved to the right, and in S11, the third fixed stitch 82 is overlapped with the end stitch of the second fixed stitch row 6 to form an overlapping stitch 86. The movement of the yarn feeder 9 in S10 is to prevent the knitting yarn from becoming tangled when the third fixed stitch 82 is moved.

After S11, on the rear needle bed BB, knitting is performed symmetrically from S7 to S10. As a result, the stitches are held in the locked state shown in S12 of FIG. 3 is obtained. When knitting a new second fixed stitch row 6 after S11, the new fixed stitch 60 is knitted in the wale direction following the fixed stitches 60 excluding the double stitches 86.

In S12 of FIG. 3, the end pile loop 71 is released from the needle bed and is in an unlocked state, while the standard pile loops 31, 41 are held in the needle bed and are in an engaged state. In S13, the standard pile loops 31, 41 are released from the needle bed. The standard pile loops 31, 41, 71 are in a state where they protrude to the inside of the pile fabric tube.

After S13, when knitting a knitted fabric portion having pile loops 31, 41, and 71, the first fixed stitch row 5 in S13 is regarded as the first stitch row 1, the second fixed stitch row 6 is regarded as the second stitch row 2, and knitting from S3 in FIG. 1 to S13 in FIG. 3 is repeated.

According to the knitting method of the pile knit fabric of this example, an end pile loop 71 can be formed at the boundary between the first pile stitch row 3 and the second pile stitch row 4. Therefore, the boundary between the first pile stitch row 3 and the second pile stitch row 4 is not noticeable. In addition, according to the knitting method of the pile knit fabric of this example, an end pile loop 71 can be formed between the first pile stitch row 3 and the second pile stitch row 4 without changing the knitting width of the pile knit fabric.

<Embodiment 2>
In the first embodiment, the additional stitches 70 are knitted on the front needle bed FB on which the first pile stitch row 3 is held. In the second embodiment, an example in which the additional stitches 70 are knitted on the back needle bed BB on which the second pile stitch row 4 is held will be described with reference to FIG.

In the second embodiment, the second stitch row 2 is moved to the right relative to the first stitch row 1 from the state S1. As a result, a non-overlapping region R1 that does not overlap with the left side portion of the first stitch row 1 is formed in the rear needle bed BB. The yarn feeder 9 is moved to the left to knit the first pile stitch row 3, and then the yarn feeder 9 is moved to the right to knit the second pile stitch row 4. At that time, before knitting the second pile stitch row 4, an additional stitch 70 is knitted in the non-overlapping region R1 of the rear needle bed BB, and an end pile loop 71 is knitted on the front needle bed FB. The knitting method of the pile fabric of this example also knits an end pile loop 71 between the end stitch 3E of the first pile stitch row 3 and the start stitch 4S of the second pile stitch row 4.

<Other embodiments>
The knitting method of the pile knit fabric according to the first and second embodiments can also be implemented by a four-bed flat knitting machine. With a four-bed flat knitting machine, the first pile stitch row 3 and the second pile stitch row 4 can be knitted in a full needle state. The full needle state means that the knitting is performed in a state where there are no empty needles between adjacent stitches. In that case, a pile knit fabric in which the pile loops 31, 41, 71 are more densely arranged can be obtained.

The knitting method of the pile knit fabric according to the first and second embodiments can also be carried out by a flat knitting machine equipped with a pile sinker. In a flat knitting machine equipped with a pile sinker, the first pile stitch row 3 and the first fixed stitch row 5 are knitted simultaneously, and the second pile stitch row 4 and the second fixed stitch row 6 are knitted simultaneously. In this case, the pile loops 31, 41, 71 are engaged with the pile sinker. The pile sinker is configured to be able to move freely toward and away from the tooth gap. Therefore, the pile loops 31, 41, 71 can be removed from the pile sinker by retracting the pile sinker from the tooth gap.

The knitting method of the pile knit fabric according to the first and second embodiments can also be implemented by a flat knitting machine equipped with compound needles. In a flat knitting machine equipped with compound needles, as in the conventional technology described with reference to FIG. 4, after the first fixed stitch row 5 is knitted, the first pile stitch row 3 is knitted so as to overlap the first fixed stitch row 5, and after the second fixed stitch row 6 is knitted, the second pile stitch row 4 is knitted in a cylindrical shape so as to overlap the second fixed stitch row 6.
