Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a stockinette knitted fabric, particularly to a rubber knitted fabric that is effective for use in rubber hem knitted parts, wrist parts, etc. of clothing.

〓Prior Art〓 Conventionally, knitted fabrics made of rubber knitted tissue have been used to impart elasticity to the hem portions of clothing such as sweaters and vests, or to the perforated portions of gloves and socks. Rubber knitted fabric is created by knitting the front and back stitches in appropriate courses, so that the threads passing between the front and back stitches are
Since the wales on the front and back sides are continuous with each other in the thickness direction of the knitted fabric and the knitted fabric is bent, it can be stretched well in the wale direction.

However, due to the structure of the knitted fabric as described above, although the knitted fabric is thick and has extensibility, it is difficult to maintain a tight state. In particular, even when knitted thinly, it was difficult to obtain a tight and tight fabric, that is, a fabric in which the ridges of the rubber knitting were clearly visible.

〓Problem to be solved by the invention〓 In view of the above points, the present invention has been developed to provide a tight and elastic fabric, even if it is a thinly finished knitted fabric.
That is, the object is to obtain a knitted fabric in which the ridges of the rubber knitting are clearly visible.

〓Means for Solving the Problem〓 In the first invention, a rubber knitted structure made of base threads, in which an appropriate number of front stitch wales and an appropriate number of back stitch wales are alternately arranged, is provided with a front stitch. An appropriate number of courses were provided by tucking heat-shrinkable yarn across the loops of the stitches and the loops of the back stitches.

In the second invention, following the first course in which front stitches and back stitches are alternately present with an appropriate number of wales made of ground yarn forming the edge of the knitted fabric, only the back stitches are formed using heat-shrinkable yarn. An appropriate number of shrinkage courses are provided, and the next course is a rib knitted structure of ground yarn in which the wales of the front stitch and the wales of the back stitch are arranged alternately, and the loops of the front stitch and the loops of the back stitch are formed. An appropriate number of courses were provided by tucking heat-shrinkable threads.

〓Operation〓 In the first invention, the tack yarn made of heat-shrinkable yarn fed between the wale loops constituting the front stitch and the wale loop constituting the back stitch heat-treats the knitted fabric. When this is done, the loops of the front and back stitches are strongly taut, but since the base yarn is not contracted, the base yarn is swollen and the ridges of the rubber knitting appear prominently.

In the second invention, similar to the first invention, the ridges of the rubber knitting are clearly visible due to the shrinkage of the tuck yarn, and the courses made of heat-shrinkable fibers tighten the edges of the knitted fabric. When this knitted fabric is used for hems, openings, wrists, etc., it retains its shape.

〓Example〓 Next, as an example of the knitted fabric of the present invention, an example of an elastic hem knit 100 knitted with a 1×1 rubber knit structure will be described.

In this example, a 1×1 rubber knitted fabric is knitted into a tubular shape using a two-bed flat knitting machine having front and back needle beds.

The carriage of the knitting machine described above has a knitting lock and a transfer lock, and when the carriage runs, the transfer lock on the leading side transfers the stitches, and the knitting is performed using the knitting cam on the trailing side.

An example of knitting this knitted fabric using a two-bed flat knitting machine will be described next.

The illustrated example is an example in which a 1×1 rubber knitted fabric is knitted in a tubular shape by a knitting machine in which front bed F and back bed B, each having needles A to Z, are provided facing each other.

As is clear from the organization chart in Figure 2, knitting starts on the front bed F side, and when the knitting on the front bed F side is completed, knitting starts on the bag bed B side, and this is done counterclockwise in the example in Figure 2. The knitted fabric is knitted into a cylindrical shape by circulating in the direction of the needles. In the organization chart shown in FIG. 2, first, the drawn thread 10 of course 1
1 is fed. The pulling yarn 101 is a yarn that is knitted at the boundary with one unit of knitted fabric (not shown) that has already been knitted, and is used to pull out the yarn after knitting and separate the knitted fabric into units. It is knitted with a plain knit structure compared to a knitted fabric. The thread 101 of course 1 is the third
As shown in Figure 1, yarn is fed to every other needle A, C, ...W of the front bed F, and when the knitting by the needles of the front bed F is completed, the course is changed in the reversal movement of the carriage (not shown). 2 formations are performed. Course 2 is knitted by back bed B using every other needle X, V, . When knitting the drawn thread 101, the needles on the needle bed that are not used are lowered to the rest position and are on standby.

Remove threads 101 for each of the front and rear beds F and B.
Once the is knitted into a circular shape, the next step is to knit course 4 using the base yarn 102, but since the texture of the knitted fabric using the base yarn 102 is a rubber knit, the front and back beds must be used. To do this, every other loop that was hanging on the needles of front bed F during knitting of course 1 must be transferred to back bed B. That is, as shown in Figure 3-3, move the loops of needles C, G, ...W of front bed F to needles C, G, ...W of back bed B, and then move the loops of needles C, G, ...W of front bed F to needles A, E, ...U of front bed F. The needle and the C of the back bed B,
Knit a rubber knit using needles G, ...W (3rd
-4 figure). The knitted fabric thus formed becomes the front knitted fabric of the hem elastic 100 knitted into a cylindrical shape. The front knitted fabric and the back knitted fabric are knitted alternately to form one garment.

Subsequently, the knitted fabric of the second knitted fabric is knitted. The first course is course 6, so that the thread 101 of course 2 is followed by the ground thread 10 as in the case of course 4.
Since course 2 must be knitted with a rubber knitting structure, the inner needles of backbed B, which knitted course 2,
Loops attached to F,...V, and loops attached to needles C, G,...W of back stitch B of front knitted fabric, B, C, F, G,...V of front stitch F,
Transfer to W needle (Figure 3-5). Then, a rubber knit is knitted using needles B, F, . . . V of the front bed F and needles D, H, . . .

Next, organize course 8 using front bed F.
Course 8 is every fourth needle A of front bed F,
In order to knit with only front bed F in E,...U, needles B, C, of front bed F other than those mentioned above are used.
Transfer the loops of F, G, . . . V, W to needles B, C, F, G, . . . V, W of backbed B (Figure 3-7).
And every fourth needle A, E of front bed F,
...U is used to organize (Figure 3-8). Needle A of front bed F, which fed this loop of course 8,
E,...U take the rest position and proceed to course 24, which will be described later.
tucks the heat-shrinkable yarn 103 that rises and is fed during knitting.

Next, in back bed B, in order to knit course 10 of the back knitted fabric using the same structure as above, needles X, T,...D are required in the above knitting of back bed B.
Needles W, V, S, excluding the loop that is locked in
Move R,...C, B to front bed F (3rd -
Figure 9). And every fourth needle X of back bed B,
Organize with T,...D (Figure 3-10). The needles X, T, ...D of the backbed B, which have locked the loops of this course 10, take a rest position and rise when knitting a course 27, which will be described later, to feed the heat-shrinkable yarn 1.
Tap 03.

Next, the course 12 of the front knitted fabric is knitted. Course 12 is every other needle C, G of back bed B,
...Knitted with back stitches by W (Fig. 3-12),
After that, several courses of loops of the heat-shrinkable yarn 103 are supported. To do this, move the loops of needles B, C, F, G, ...V, W of front bed F and every second needle to back bed B, and lower front bed F to the yarn feeding position of A, E, ...U. The front knitted fabric is supported by the needles, and the front knitted fabric is back-bedded B.
The back stitches are knitted using every third needle C, G, ...W (Figure 3-12).

After knitting the above-mentioned front knitted fabric, course 14 of the back knitted fabric is knitted. Therefore, contrary to the above, the front knitted fabric hung on the needles of W, V, S, R, ...C, B of back bed B,
Transfer the loop of the back knitted fabric to the front bed F (3rd
-13). Then, the plain stitches of the back stitch are knitted using every three needles V, R, . . . B of the front bed F (Fig. 3-14).

Next, course 1 following course 12 in the front knitted fabric
Perform formation 6. From this course 16, a plurality of courses (two courses in the example shown in the second figure) of the heat-shrinkable yarn 103 having the same structure as the course 12 is fed. Therefore, in the same way as when knitting course 12, needles B, C, F, G, ... V, W of front bed F are transferred to back bed B (Fig. 3-15), and needles C, G, ... of back bed B are moved. A plain knit structure is knitted by W (Fig. 3-16).

Next, course 18 of the second knitted fabric is knitted. The course 18 has the same structure as the course 14, and uses the same needles as used in knitting the course 14. That is, move needles B, C, F, G, ...V, W of back bed B to front bed F (Fig. 3-17),
A plain knitting structure is formed by F,...V (3-1)
Figure 8).

To knit course 20 of the previous knitted fabric of the next course, move needles B, C, F, G, ... V, W of front bed F to back bed B (Fig. 3-19) in exactly the same way as knitting course 16. B's needles C, G,
...Knit a single-knit structure by W (3-20)
figure).

To knit the subsequent course 22 of the back knitted fabric, move the needles B, C, F, G, ... V, W of the back bed B to the front bed F (Fig. 3-21) in exactly the same way as when knitting the course 18. Needle B of bed F,
A plain knitting structure is formed by F,...V (3-2
Figure 2).

Course 16 to course 2 of the above front knitted fabric 104
The knitted fabrics up to 2 constitute a plain knitted fabric with wales formed by needles C, G, ...W, and the knitted fabrics of course 8, needles A, E,
...Constitutes a double knitted fabric with a portion of a plain knitted structure having wales due to U. And the former needles C, G,
...A plain knitted fabric with wales made of W is knitted using heat-shrinkable yarn, and therefore shrinks by the heat treatment described below.

In the next course 24, the tack yarn of the heat-shrinkable yarn is fed, and then the double plain knit structure portions described above are combined into a single rubber knit structure. That is, move the loops of needles B, C, F, G, ... V, W of front bed F to needles B, C, F, G, ... V, W of back bed B (Fig. 3-23), and needle A,
The heat-shrinkable yarn 103 is fed as the tack yarn of the course 24 to the needles C, G, . Next, thread 1 of the ground thread onto the above needle.
Feed yarn 02 and move needles A, E,... of front bed F.
The front side is knitted with the needles C, G, ... W of the back stitch B, and the part 107 where the tack yarn 106 is knitted into the rubber knitted fabric made of the base yarn 102 is knitted into the front knitted fabric 104 (3rd- Figure 25).

Tack yarn 10 is applied to the rubber knitted fabric made of the ground yarn 102.
The part 107 in which 6 is knitted is knitted into the back knitted fabric 105 following knitting of the front knitted fabric 104. Transfer the loops of needles B, C, F, G, ... V, W of back bed B to the front bed (Fig. 3-26), and move the loops of needles B, F, ... V of front bed F and needles D, H of back bed B. ,...Feed the heat-shrinkable yarn 103 to X as the tack yarn of course 27 (No. 3-27
figure). Next, the ground yarn 102 is fed to the above-mentioned needles, and the back side of the second knitted fabric is knitted with the needles B, F, ...V of the front bed F, and the front side of the front knitted fabric is knitted with the needles D, H, ...X of the back bed B, respectively. A portion 107 in which the tack yarn 106 is knitted into the rubber knitted fabric made of the base yarn 102 is knitted into a back knitted fabric 105 (FIG. 3-28).

Tack yarn 1 is applied to the rubber knitted fabric made of the above ground yarn 102.
The part 107 where 06 is knitted is the front and back knitted fabric 104,
105 is knitted into appropriate courses and used as hem elastic. Therefore, a predetermined number of courses are repeated from FIG. 3-23 to FIG. 3-28.

In the above portion 107, the heat-shrinkable thread 103
However, when the ground yarn 102 is knocked over, the tacked yarn 106 does not appear on the surface and is buried in the sections of the knitted fabric, making it impossible to tell that it is being used. If the heat-shrinkable yarn is contracted by heat-treating the knitted fabric, the shrinkage force will be further increased, resulting in a tight and tight fabric with sharp ridges in the rubber knitting. be made to appear.

<Effects of the Invention> In the first aspect of the present invention, a rubber knitted structure made of ground yarn is provided with a rubber knitted structure made of ground yarn, in which an appropriate number of front stitch wales and an appropriate number of back stitch wales are alternately arranged. Because an appropriate number of courses made of heat-shrinkable yarn are provided between the loops of the stitches and the loops of the back stitches, the heat spread between the wales that make up the front stitches and the wales that make up the back stitches. The tactile yarn made of shrinkable yarn strongly tensions the base yarns forming the front and back stitches, making the ridges of the rubber knitting noticeable, creating a tight knit with high stretchability. You can get land.

In the second invention, following the first course in which front stitches and back stitches are alternately present with an appropriate number of wales made of ground yarn forming the edge of the knitted fabric, only the back stitches are formed using heat-shrinkable yarn. An appropriate number of shrinkage courses are provided, and the next course 1 is a rib knitted structure of ground yarn in which wales of the front stitch and wales of the back stitch are arranged alternately, and loops of the front stitch and loops of the back stitch are formed. By providing an appropriate number of courses made by tucking heat-shrinkable yarn across the knitted fabric, a type of double-knitted structure consisting of front stitches and back stitches is formed at the edge of the knitted fabric, and the heat-shrinkable fibers in this area are The yarn course tightens the edges of the knitted fabric, and when this knitted fabric is used for the hem of clothing, the wrist part of sleeves, the ankle part of legs, the wrist part of gloves, etc., it is effective for tightening those parts. be.
