Description

[Detailed description of the invention] The present invention relates to a novel weft knitted fabric.

As shown in Figure 1, in conventional weft knitted fabrics, the knitting yarns are deformed in a certain direction and have strain and internal stress in a certain direction, so the knitted fabric tends to curl, causing many problems in handling. I'm here.

This tendency is particularly noticeable when the knitted fabric is stretched in the warp direction, causing troubles such as so-called ear wrapping, which becomes a major obstacle in handling.

Here, FIG. 1A is a front view of a conventional weft knitted fabric seen from the front side, and FIG. 1B is a sectional view taken along the line X-X' in FIG. 1A.

An object of the present invention is to improve the above-mentioned drawbacks of conventional knitted fabrics and to propose a new weft knitted fabric that has a woven-like appearance.

That is, the present invention provides a weft knitted fabric substantially consisting of a combination of knit knitting and welt knitting, in which the weft yarns of the welt knitting part are
The weft knitted fabric is characterized in that it has a structure arranged on the face side of the knit stitch loop so as to be located outside the stitch loop.

The present invention will be explained in detail below.

In the present invention, knitting means a normal knitting method knitting in a weft knitted fabric as shown in Fig. 1, and the front side of a stitch loop is a knitting method in which knitting yarns are mainly arranged in the warp direction. This refers to the side that looks like this.

That is, as shown in FIG. 1A, a new stitch loop is formed by passing the knitting yarn that will become the new loop through the loop that has already been knitted, but at this time, the new loop is drawn out from the old loop. (In FIG. 1A, the new loop is pulled out from the back side of the page to the front side, so the front side of the page becomes the front side of the stitch loop.)

In addition, welt knitting refers to a knitting method in which a knitting error occurs, and even if new yarn is supplied, the needle does not form a stitch loop, and therefore this yarn is arranged in the weft direction of the knitted fabric, and in the present invention, the needle does not form a stitch loop. It forms the so-called "weft yarns of the welt knitting section."

Hereinafter, the weft knitted fabric of the present invention will be explained with reference to the drawings.

FIG. 2 is a diagram showing a weft knitted fabric according to an embodiment of the present invention,
Figure 2A is its plan view, Figure 2B is Y-Y of Figure 2A.
FIG.

The knitted fabric shown in Fig. 2 is knitted by repeating welt knitting and knitting in each course and each well. The figure shows a knitted fabric that is arranged and intertwined on the surface side of the formed stitch loop so as to be above the stitch loop.

That is, when welting in the (i) course of the (i) wale, the weft yarn 1 of the welt knitting section is in the (i) wale to which the welt section belongs, and the loop formed by knitting in the (i) course. It is knitted so that it is placed on the front side of No. 2.

Since the weft knitted fabric of the present invention is knitted in such a structure,
As shown in Figure 2B, the bending of the threads 1 constituting the knitting from the front side to the back side and the bending in the opposite direction can be made approximately the same, so the internal stress is balanced. It maintains properties similar to those of a woven fabric, and does not cause deformation of the knitted fabric, especially curling of the knitted fabric, which makes the fabric extremely easy to handle. Even when added, the phenomenon of ear wrapping does not occur, and the processability is extremely good from the viewpoint of the structure.

From the above-mentioned point of view, it is preferable that the knitted fabric of the present invention has approximately the same number of knit stitches and welt stitches, and that they are uniformly dispersed.

For example, as shown in Figure 2, the welt knitting and knitting knitting are repeated in the weal and course, and this is abbreviated as (number of knit repeats) - (number of welt repeats).
-1, or 2-2, 3-3, 4-4
. . . or a combination of these may be used.

In addition, the balance between the number of knit stitches and the number of welt stitches may be locally disturbed in order to add a pattern or pattern, or a tack may be incorporated as the case requires.

Next, to illustrate the method of obtaining the knitted fabric of the present invention, Fig. 2A
When knitting a welt knitted section, in the i-wale to which the welted knitted section belongs, the previous course (in the figure, the stitch loop formed by knitting at (ii)) 2 is held at the yarn feeder on the back stitch side from the tuyere of the needle bed, knitted in a welt, and then knitted in a usual manner to form a stitch loop by knitting.

In this method, in order to grasp the stitch loop 2 on the back stitch side, it is possible to transfer the stitch loop 2 with a transfer needle and grasp it, or to use a double bed such as a purl knitting machine with a single-head, single-crochet needle (one with a beard needle head or a flat needle head). When forming stitch loops in knit knitting, knit as usual at the head, and when knitting in welt knitting, knit in the previous course. Examples include a method of knitting by hooking the knitted stitch loop onto the hook at the other end and moving the needle to another needle bed.

Since the knitted fabric of the present invention has the above-mentioned structure, thirdly, as shown in the figure, it has a special appearance and feel as a woven-like weft knitted fabric in which interlacing of warp and warp yarns can be seen. Moreover, it does not cause any curling (ear wrapping) phenomenon and has extremely good fabric handling properties.Furthermore, because it has many tissue points, it has excellent dimensional stability and good stretch back, and also has excellent post-processing properties such as raising. It is a knitted fabric with
