Description

The present invention relates to a method of knitting a knitted fabric using a first yarn and a second yarn, and a knitted fabric.

In addition to the first yarn made of inelastic yarn, a second yarn such as elastic yarn may be knitted into the knitted fabric. The second thread is knitted into the knitted fabric by tack, but it cannot be said that it is firmly knitted into the knitted fabric. For example, in Patent Document 1, when knitting a sock tightening portion (a portion requiring a tightening force on a foot), a course for knitting knit stitches of inelastic yarn and a course for knitting tack stitches of elastic yarn are provided. repeat. Since the elastic thread is only temporarily fixed in the tack, the crossover thread part of the elastic thread may be caught by the human body or the like when worn.

Patent No. 4919522

The subject of this invention is
-By knitting the second yarn into the knitted fabric so as to form knit stitches instead of tack stitches, the second yarn is firmly knitted into the knitted fabric.
-The second thread is to make it inconspicuous on the surface of the knitted fabric. The tack eyes are originally inconspicuous. Therefore, making the second yarn inconspicuous is a problem that arises with the formation of the knit stitch of the second yarn.

The method for knitting a knitted fabric of the present invention is a method of knitting a knitted fabric with at least a first yarn and a second yarn with a flat knitting machine.
The stitches connected to each other by the crossover thread are used as the course, and the stitches in which the stitches are locked to each other are used as the wales.
The steps to knit the knitted course of the first thread,
The steps to organize the course of the knit stitch of the second thread,
It is characterized by performing a step of transferring a part of the knit stitch on the wales including the knit stitch of the second thread so as to overlap and hide the knit stitch of the first thread of the adjacent wales. do. The knit stitch to be transferred may be the knit stitch of the second thread or the knit stitch of the first thread.

The knitted fabric of the present invention is a knitted fabric composed of at least a first yarn and a second yarn.
The stitches connected to each other by the crossover thread are used as the course, and the stitches in which the stitches are locked to each other are used as the wales.
The course of the knit stitch of the first thread and
With a second thread knit course,
A part of the knit stitch on the wales including the knit stitch of the second thread is overlapped so as to be hidden by the knit stitch of the first thread of the adjacent wales.

In the present invention, since the second yarn is knitted into the knitted fabric with knit stitches instead of tack stitches, the second yarn can be firmly knitted into the knitted fabric. Further, the knit stitches of the second thread are connected to the other knit stitches on the top, bottom, left and right, and can be reliably fixed to the knitted fabric. Also, when a part of the knit stitches on the wales including the knit stitches of the second thread are transferred and overlapped with the knit stitches of the first thread of the adjacent wales, the transferred knit stitches are hidden behind the knitted fabric. , It becomes difficult to see from the surface of the knitted fabric. Here, even when the knit stitch of the first thread following the knit stitch of the second thread is transferred (for example, FIG. 1 of the embodiment), the knit stitch of the second thread is also transferred together with the knit stitch of the knitted fabric. Hide on the back.

Preferably, the empty needle generated by the stitch transfer is used to knit the hook of the first thread or the second thread, and a knit stitch of the second thread is formed on the wale containing the hook, for example, following the hook. In this case, the wales containing the knit stitches of the second yarn start with a hook and end with a lap stitch. In this specification, the hook is formed into an empty needle by the knit operation, and the hook is included in the knit stitch.

In addition, in the design of the knitted fabric, the wales that include the knit stitch of the second thread and start with the hook stitch and end with the lap stitch are continued multiple times in the wales direction, in other words, the position of the wales in the course direction is constant. It is preferable to arrange them so as to be. In this way, the knit stitches of the second yarn are regularly arranged on the same wales.

At least the second yarn contains an elastic yarn, the first yarn has a different elastic force than the second yarn, and at least one needle is skipped in the step of knitting the knitted course of the second yarn. Repeat knitting the knit stitches multiple times. In addition to the combination of the first thread as an inelastic thread and the second thread as an elastic thread, both the first thread and the second thread are elastic threads, and the first thread has relatively weak elasticity and the second thread. The thread may be such that the elasticity is relatively strong. The elastic yarn is arranged on the back side of the knitted fabric and contracts when the knitted fabric is removed from the knitting machine. As a result, the inelastic yarn having low elasticity swells on the surface side of the knitted fabric, and the knitted fabric becomes three-dimensional. Further, since at least one needle is skipped to form the course of the knit stitch of the second thread, the knit stitch of the second thread and the knit stitch are crossed threads consisting of mistaken stitches. This crossover thread comes into contact with the first thread, and the second thread becomes difficult to move.

Further, when a tubular knitted fabric such as socks, gloves, supporters, and pipe covers is knitted by the method of the present invention, a tightening force can be applied to the knitted fabric by the elastic yarn.

The ratio of the number of knit stitches of the second thread to the number of knit stitches of the first thread, the ratio of the wales containing the second thread and the wales not containing the second thread, and when forming the knit stitches of the second thread. In addition, the number of wales to fly is arbitrary.

Preferably, a main yarn and a splicing yarn are used as the second yarn, and the main yarn and the splicing yarn are plated and knitted. In this way, various knitted fabrics can be knitted. For example, the main thread is an elastic thread such as a rubber thread, and the additional thread is a thread that is thicker than the elastic thread and has low elasticity. Since the elastic yarn is knitted by applying tension, the elastic yarn contracts when it is removed from the weft knitting machine, and the yarn covers the elastic yarn on the back surface of the knitted fabric, resulting in a pseudo-pile-like knitted fabric. In addition, although some main yarns such as elastic yarns are not soft to the touch, the main yarns can be covered with a splicing yarn. Further, if both the main yarn and the auxiliary yarn are elastic yarns, a knitted fabric having a strong tightening force can be knitted. The type of thread to be added is arbitrary, and a plurality of threads may be used as the thread to be added.

The following are the optimum examples for carrying out the invention.

Example 1
FIG. 1 shows the knitting method according to the first embodiment, and the knitting is performed by a flat knitting machine provided with at least two needle beds and the stitches can be freely transferred. The uppercase letters A to O in FIGS. 1 to 3 indicate the positions of the needles on the rear needle bed, and the lowercase letters a to o indicate the positions of the needles on the front needle bed. Black dots indicate needles, circle marks indicate knit stitches, V marks indicate hook stitches, and double circle marks indicate overlapping stitches. The inverted triangle mark indicates the yarn feeding port, the arrow indicates the stitch transfer direction, and the left and right arrows indicate the knitting direction.

FIG. 1 shows the arrangement of the front needle bed (F.B.) and the rear needle bed (B.B.). The relationship between the front and back of the knitted fabric is also shown. Except for the place where the knitting using the second yarn such as the elastic yarn is performed, for example, the first yarn made of the inelastic yarn is used for knitting. For knitting, repeat steps 1) to 6) in the order from step 1) to step 6), and display the number of needles and stitches less than the actual number. Further, the yarn feeder 1 is fed with a first yarn, the yarn feeder 2 is fed with a second yarn such as an elastic yarn, and the knit stitches and hooks of the second yarn are shown with hatching. These displays are also common to FIGS. 2 and 3. The sock is knitted into a cylindrical shape with the first thread, and the arch, the heel, and other parts requiring a tightening force are knitted with the second thread and the first thread. FIG. 1 shows the knitting of a portion that requires a tightening force. The knitted fabric to be knitted is not limited to a cylindrical shape.

In step 1) of FIG. 1, the first thread is used for reciprocating knitting, and at this time, the hooks are knitted on the hands a, e, C, and G. The hook is formed by advancing and retreating the empty needle in the same manner as when forming the knit stitch. In step 2), the knit stitches (first thread) of the needles c, g, A, and E are overlapped with the knit stitches of d, h, B, and F to form a lap stitch. In step 3), the knit stitches of the second thread are knitted on the hooks (first thread) of the needles a, e, C and G. The knit stitch of the second thread is formed by skipping three stitches. The second yarn is, for example, a rubber yarn, but other elastic yarns may be used and knitted in a state of being stretched by applying tension, and when the knitted fabric is removed from the flat knitting machine, the second yarn contracts.

In steps 4) to 6), the same knitting as in steps 1) to 3) is performed by shifting the needle allocation. In the whole of steps 1) to 6)
・ Knit and hook stitches are knitted with the first thread (steps 1 and 4).
-Move the knit stitch of the first thread to form a lap stitch (steps 2 and 5)).
-Knit the knit stitch of the second thread with respect to the hook stitch (steps 3 and 6)).
In steps 3 and 6), the knit stitches of one course of the second thread are knitted in two steps, but may be knitted in three or four steps, for example. By knitting the knit stitch course of the second thread in multiple times, the knitted fabric becomes thicker, and even if the second thread breaks, the knit stitches are solved one after another along the course direction. Can be prevented.

The second thread may be a thread other than the elastic thread, for example, a thread having a deodorizing action, a bactericidal action, or the like, a Japanese paper thread, a mineral thread, or the like. Since these yarns are different in appearance, properties and the like from inelastic yarns, it is preferable that they do not appear on the surface of the knitted fabric. Further, when elastic yarn is used only for a part of the knitted fabric and the other part of the knitted fabric is knitted with the inelastic yarn, it may be desired that only the inelastic yarn appears on the surface of the knitted fabric. In these cases, it is necessary to hide the second thread on the back surface of the knitted fabric.

Regarding the knit stitch of the second thread (knitted with needles a, e, C, G), the knit stitch of the first thread formed next with the same needle is transferred in steps 2) and 5), and the stitch is transferred. The knit stitch of the first yarn is moved to the back surface of the knitted fabric. At this time, the knit stitches of the second thread are also hidden behind the knitted fabric, making it difficult to see from the surface of the knitted fabric. Further, by performing the stitch transfer, for example, twice and moving the stitches to form a layered stitch, a mesh structure is imparted in which the holes of the traces of the stitches being moved are in the knitted fabric. In the case of apparel products, the mesh structure increases the breathability of the knitted fabric, and the layering adds some thickness.

There is a crossover yarn for 3 wales between the knit stitches of the second yarn, and the crossover yarn is less likely to shift due to friction with the first yarn, and the second yarn is less likely to stretch. Further, the knit stitch of the second thread is cut off from the connection along the wale direction by the stitch transfer. That is, the knit stitches of the second thread are repeatedly formed by the needles a, e, C, G, etc., but the stitches are transferred between the upper and lower knit stitches of the second thread, and the connection between the upper and lower knit stitches is established. Cut off. Therefore, even if the second thread such as the elastic thread is broken, the knit stitches connected in the wale direction are not unraveled one after another. It should be noted that elastic yarns are more likely to deteriorate than ordinary yarns and are therefore more likely to break.

Example 2
FIG. 2 shows the knitting method in the second embodiment, and is the same as the first embodiment except for the points described below. In step 1), skip one stitch at a time to knit the knit stitch with the normal first thread, and in the two courses of steps 2) and 3), skip three stitches at a time to hook the stitches with the second thread such as elastic thread. Form. In the two courses of steps 4) and 5), a knit stitch is formed by the second thread on the hook. Also at this time, the knit stitches are skipped by 3 stitches and formed every 4 stitches. In step 6), the knit stitches of the second thread are transferred and overlapped with the knit stitches of the first thread. Next, return to step 1) and repeat the cycle consisting of steps 1) to 6).

Since the knit stitches of the second thread are transferred in step 6), the knit stitches and hooks of the second thread knitted in steps 2) to 5) are hidden behind the knitted fabric. In addition, there are three stitches of crossover thread between the knit stitches and the hook stitches of the second thread of the same course, and they come into contact with the first thread to stretch the second thread. Suppress. Further, the connection between the knit stitches of the second thread along the wales direction is cut by the transfer in step 6), so even if the second thread is broken, the knit stitches of the second thread are wales. There is no unraveling in large numbers along the direction.

Modification Example FIG. 3 shows the modification of the second embodiment, and is an example in which a rubber thread is arranged as a knit stitch on a part of a tubular knitted fabric. The same applies to Examples 1 and 2 except for the points particularly shown. The knitted fabric is knitted into a cylindrical shape using the first thread, and the stitches are moved by stitch transfer in step 1) to form a mesh pattern having holes in the knitted fabric at the position of an empty needle. The inside of the cylinder in FIG. 3 is the back side of the knitted fabric. The empty needles b, f, D, and H generated by the transfer are hooked with the first thread (step 2)), and the knit stitch of the second thread made of the elastic thread is formed on the needle having the hook formed by the second thread. (Steps 3) to 6)). Then, in step 7), the knit stitches of the second thread are transferred from the needles b, f, D, H to the needles cg, E, I, and are overlapped with the knit stitches of the adjacent first thread. Then, steps 2) to 7) are repeated.

FIG. 4 shows the inside of the sock knitted in the first embodiment. As the second thread, a main thread G made of rubber thread (looks gray in the figure) and a needle thread made of elastic thread having a lower expansion / contraction rate than the rubber thread (looks black in the figure) are used. Was fed to the same needle, and the plating area P was plated. S is a knitted fabric knitted only with the first thread. The gray thread visible in the plating area P is the first thread, and the rubber thread G is slightly visible around the plating area P. This is because when the knitted socks are removed from the flat knitting machine, the rubber thread G having a high expansion / contraction rate contracts and is hidden behind the elastic thread of the thread. It may be disliked that the rubber thread G comes into direct contact with the skin, but the elastic thread covers the rubber thread G and the rubber thread G does not come into contact with the skin.

5 and 6 show a part of socks plated and knitted using a rubber thread as a main thread and a thread having a low expansion / contraction rate and a thick thread as a thread. The triangular portion (the portion with the mesh) on the right side of FIG. 5 is the position of the arch at the tightening portion using the rubber thread and the thread, and neither the rubber thread nor the thread is visible from the surface of the sock. In addition, because the thread is thick and difficult to stretch, the knitted fabric is thick and has high cushioning properties. FIG. 6 shows the inside of the sock, the rubber thread is contracted and hardly visible, and the thread is swelled like a pile knitted fabric.

It should be noted that the direction in which the knit stitches are brought together may be either left or right, and it is not necessary to align the directions. However, since the appearance of the knitted fabric changes depending on the arrangement of the holes and the layers in the mesh structure, it is preferable to arrange them regularly. Further, when forming the lap stitch, by arranging the lap stitch on the back side of the lap stitch, the second thread can be surely hidden.

The knitted fabric to be knitted is not limited to a tubular knitted fabric such as socks, gloves, supporters, and shoe uppers, but can also be used for a flat chair cover or the like having a high cushioning property. Further, if a heat insulating yarn, a high-strength yarn, or the like is used instead of the elastic yarn, a heat-insulating knitted fabric, a high-strength protective knitted fabric, or the like can be knitted.
