Description

Knitting method of knitted fabric and knitted fabric
Technical Field
The present invention relates to a knitting method of a knitted fabric using a first yarn and a second yarn, and a knitted fabric knitted by the method.
Background
In some cases, a second yarn such as an elastic yarn is knitted in addition to the first yarn made of the inelastic yarn. The second yarn is knitted into the knitted fabric by tucking, but it is hard to say that the second yarn is firmly knitted into the knitted fabric. For example, in patent document 1, when knitting a tight part (a part requiring a tightening force to a foot) of a sock, a stitch course for knitting a loop of an inelastic yarn and a stitch course for knitting a tuck of an elastic yarn are repeated. In tucking, since the elastic yarn is only temporarily fixed, the connecting yarn portion of the elastic yarn may be caught by a human body or the like and be displaced when worn.

Disclosure of Invention
The subject of the invention is:
knitting the second yarn into the knitted fabric not in a tuck-stitch forming manner but in a loop-forming manner, thereby firmly knitting the second yarn into the knitted fabric;
the second yarn is made inconspicuous on the front surface of the knitted fabric.
Tucks are inherently difficult to visualize. Therefore, making the second yarn inconspicuous is a problem associated with the formation of loops in the second yarn.
The knitting method of a knitted fabric of the present invention is a knitting method of a knitted fabric using at least a first yarn and a second yarn on a flat knitting machine,
the following steps are performed with the courses connected to each other by the connecting yarn set as course and the courses engaged with each other set as wale:
knitting a looped course of a first yarn;
knitting a looped course of a second yarn; and
a portion of the loops in the wales including the loops of the second yarn are transferred overlapping the loops of the first yarn in adjacent wales and hidden from the loops of the first yarn in adjacent wales.
The loops to be transferred can be loops of both the second yarn and the first yarn.
The knitted fabric of the present invention is a knitted fabric comprising at least a first yarn and a second yarn,
the stitch rows connected to each other by the connecting yarn are set as course rows, the stitch rows in which the stitches are hooked to each other are set as wales,
comprising courses of a first yarn and courses of a second yarn,
a portion of the loops in the wales, including the loops of the second yarn, overlap the loops of the first yarn of an adjacent wale in a manner that hides the loops of the first yarn of the adjacent wale.
In the present invention, the second yarn is knitted into the knitted fabric not by tucking but by knitting, so that the second yarn can be firmly knitted into the knitted fabric. The upper, lower, left, and right sides of the loop of the second yarn are connected to other loops, so that the loop of the second yarn can be reliably fixed to the knitted fabric. If a part of the wales including the loop of the second yarn is looped and overlapped with the loop of the first yarn of the adjacent wale, the loop after the loop is looped is hidden on the back side of the knitted fabric and is difficult to be seen from the front side of the knitted fabric. Here, in the case of transferring the loop formation of the first yarn following the loop formation of the second yarn (for example, fig. 1 of the embodiment), the loop formation of the second yarn is also hidden on the back surface of the knitted fabric together with the loop formation after the transfer.
Preferably, the loops of the first or second yarn are knitted by using the empty needles generated by the transfer, and the loops of the second yarn are formed, for example, by connecting the loops, in the wale including the loops. In this case, the wale including the loop formation of the second yarn starts with a hook and ends with an overlap loop. In this specification, a loop is formed on an empty needle by a looping operation, and the loop is included in the loop.
In designing the knitted fabric, it is preferable that wales including stitches of the second yarn and ending with overlapped stitches at the start of stitch formation are arranged a plurality of times so as to be continuous in the wale direction, in other words, so that the positions of the wales in the course direction are constant. In this way, the loops of the second yarn are regularly arranged in the same wale.
At least the second yarn includes an elastic yarn, the elastic force of the first yarn is different from the elastic force of the second yarn, and the step of knitting the knitted course of the second yarn is repeated a plurality of times while skipping at least 1 or more needles. In addition to the first yarn being a combination of a non-elastic yarn and an elastic yarn being the second yarn, the first yarn and the second yarn may both be elastic yarns, the first yarn having a relatively weak elasticity and the second yarn having a relatively strong elasticity. The elastic yarn is arranged on the back side of the knitted fabric, and when the knitted fabric is removed from the knitting machine, the elastic yarn contracts. As a result, the inelastic yarn having low stretchability swells on the front side of the knitted fabric, and the knitted fabric becomes three-dimensional. Since the knitted course of the second yarn is knitted while skipping over at least 1 needle, a connecting yarn composed of a knitted loop of the second yarn is formed between the knitted loops of the second yarn. The connecting yarn is in contact with the first yarn and the second yarn is difficult to move.
When a tubular knitted fabric such as a sock, a glove, a body protector, or a cover for a tube 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 loops of the second yarn to the number of loops of the first yarn, the ratio of wales including the second yarn to wales not including the second yarn, the number of wales skipped when forming loops of the second yarn, and the like are arbitrary.
Preferably, plating knitting is performed by the main yarn and the plating yarn using the main yarn and the plating yarn as the second yarn. In this way, various knitted fabrics can be knitted. For example, the main yarn is an elastic yarn such as a stretch yarn, and the plating yarn is a yarn thicker than the elastic yarn and having a lower stretchability. Since the elastic yarn is knitted by applying tension, when the elastic yarn is removed from the flat knitting machine, the elastic yarn contracts, and plating is performed on the back surface of the knitted fabric to cover the elastic yarn, thereby forming a knitted fabric having a substantially loop shape. The main yarn such as the elastic yarn is not good in touch but can be covered by plating. If both the main yarn and the plating yarn are elastic yarns, a knitted fabric having a strong tightening force can be knitted. The plating may be of any type, and a plurality of plating yarns may be used.

Detailed Description
The following shows preferred embodiments for practicing the invention.
[ examples ] A method for producing a compound
Example 1
Fig. 1 shows a knitting method in example 1, in which knitting is performed on a flat knitting machine having at least 2 needle beds and capable of transferring stitches. Capital letters a to O in fig. 1 to 3 indicate the positions of the needles of the rear needle bed, and lowercase letters a to O indicate the positions of the needles of the front needle bed. The black dots represent needles, the circle symbol represents looping, the V symbol represents hanging loops, and the double circle symbol represents overlapping loops. The inverted triangle symbol indicates a yarn feeder, the arrow indicates a stitch transfer direction, and the right and left arrows indicate a knitting direction.
The arrangement of the front needle bed (F.B.) and the back needle bed (b.b) is shown in fig. 1. The relationship between the front and back of the knitted fabric is also shown. The knitting is performed using a first yarn made of, for example, an inelastic yarn, except for a portion where the knitting is performed using a second yarn such as an elastic yarn. Knitting is repeated from step 1) to step 6) in the order of step 1) to step 6), and the number of needles and stitches is shown smaller than actually. The yarn feeder 1 feeds a first yarn, the yarn feeder 2 feeds a second yarn such as an elastic yarn, and the loop formation and loop hanging of the second yarn are shown with hatching. These representations are also common to fig. 2 and 3. The first yarn is used for weaving the sock into a tubular shape, and the second yarn and the first yarn are used for weaving parts needing tightening force, such as the arch of the foot, the heel and the like. Fig. 1 shows the weaving of the part requiring a tightening force. The knitted fabric is not limited to a tubular shape.
In step 1) of fig. 1, the first yarn is used for the reciprocating knitting, and in this case, the knitting of the pick-up stitches is performed on the needles a, e, C, and G. The loop is formed by advancing and retreating the empty needle in the same manner as in the formation of the loop. In step 2), the stitches of the needles c, g, a, and E (first yarns) are overlapped with the stitches of d, h, B, and F to form overlapped stitches. In step 3), loops of the second yarn are knitted on the loops (first yarn) of the needles a, e, C, G. The loop formation of the second yarn is formed by skipping 3 needles. The second yarn is, for example, an elastic yarn, but may be another elastic yarn, and the second yarn is knitted in a stretched state by applying tension, and contracts when the knitted fabric is removed from the flat knitting machine.
In steps 4) to 6), knitting is performed in the same manner as in steps 1) to 3) with the needle allocation changed. In the totality of steps 1) to 6),
knitting loops and hanging loops by a first yarn (steps 1, 4));
forming overlapping loops by moving the loop of the first yarn (steps 2, 5))
Looping of the second yarn for looping (steps 3, 6)).
In steps 3 and 6), the knitting of 1 course of the second yarn is divided into 2 times and knitted, but may be divided into 3 times or 4 times and knitted, for example. By dividing the course of the loop of the second yarn into a plurality of times and knitting, a thickness is generated in the knitted fabric, and even when the second yarn is broken, it is possible to prevent the loops from being sequentially separated in the course direction.
The second yarn may be a yarn other than the elastic yarn, for example, a yarn having a deodorizing action, a sterilizing action, or the like, a yarn of japanese paper, a mineral yarn, or the like. These yarns are different from the inelastic yarns in appearance, properties, and the like, and therefore it is sometimes preferable not to appear on the front surface of the knitted fabric. When an elastic yarn is used only for a part of a knitted fabric and a non-elastic yarn is used for the other part of the knitted fabric, it may be desirable to make only the non-elastic yarn appear on the front surface of the knitted fabric. In these cases, the second yarn needs to be hidden on the back side of the knitted fabric.
In the knitting of the second yarn (knitting with needles a, e, C, and G), the knitting of the first yarn formed next with the same needle is transferred in steps 2 and 5), and the knitted loop of the first yarn after the transfer is moved to the back side of the knitted fabric. At this time, the loop formation of the second yarn is also hidden on the back side of the knitted fabric, and is difficult to see from the front side of the knitted fabric. The overlapped stitches are formed by moving the stitches while performing the transfer, for example, 2 times, and the holes to which the marks after the stitches are moved are present in the mesh structure of the knitted fabric. In the case of a long garment product, the air permeability of the knitted fabric is increased by the mesh structure, and a slight thickness is added by overlapping stitches.
Between the loops of the second yarn there are 3 wales of connecting yarn which is difficult to deflect due to friction with the first yarn and difficult to stretch. The loop of the second yarn is cut off in the wale direction due to the transfer. That is, although the stitches of the second yarn are repeatedly formed by the needles a, e, C, G, and the like, the stitches are transferred between the upper and lower stitches of the second yarn, and the connection between the upper and lower stitches is cut. Therefore, even if the second yarn such as the elastic yarn is broken, the loops connected in the wale direction do not sequentially unravel. The elastic yarn is more likely to be broken because it is more likely to deteriorate than a normal yarn.
Example 2
Fig. 2 shows a knitting method in example 2, and is the same as in example 1 except for the following points. In step 1), 1 needle 1 skips and stitches are formed with a normal first yarn, and in 2 courses of steps 2) and 3), 3 needles 3 skips and stitches are formed with a second yarn such as an elastic yarn. And in the 2 stitch courses in the steps 4) and 5), forming loops based on the second yarns in the hanging loops. At this time, 3 needles were also skipped 3 needles and loops were formed every 4 needles. And 6), enabling the loop formation of the second yarn to be transferred and overlapped with the loop formation of the first yarn. Subsequently, the process returns to step 1), and the loop including steps 1) to 6) is repeated.
In step 6), the second yarn is looped, and therefore the loop formation and the loop hanging of the second yarn knitted in steps 2) to 5) are hidden on the reverse side of the knitted fabric. The second yarn of the same course has 3 connecting yarns between loops and between loops, and contacts with the first yarn to suppress the stretching of the second yarn. Moreover, the connection between the stitches of the second yarn in the wale direction is cut by the stitch transfer of step 6), and therefore even if the second yarn is broken, the stitches of the second yarn do not largely unravel in the wale direction.
Modification example
Fig. 3 shows a modification of example 2, in which an elastic yarn is arranged as a loop in a part of a tubular knitted fabric. Except for the aspects specifically shown, the same as in examples 1 and 2. The knitted fabric is knitted into a tubular shape using the first yarn, and the stitches are moved by the transfer in step 1), so that a mesh pattern in which holes are present in the knitted fabric is formed at the position of the empty needle. The inner side of the tube in fig. 3 is the reverse side of the knitted fabric. Loops are formed by the first yarn on the empty needles b, f, D, and H generated by the transfer (step 2)), and loops of the second yarn made of the elastic yarn are formed by 2 loops on the needles on which the loops are formed (steps 3 to 6)). Then, in step 7), the loop of the second yarn is transferred from the needles b, f, D, H to the needles c, g, E, I, overlapping the loop of the adjacent first yarn. And, repeating steps 2) to 7).
Fig. 4 shows the interior of the knitted sock in example 1. As the second yarn, a main yarn G (gray in the drawing) made of an elastic yarn and a plating yarn (black in the drawing) made of an elastic yarn having a lower stretch ratio than the elastic yarn are used, and the main yarn and the plating yarn are supplied to the same needle to plate and knit the plating region P. S is a knitted fabric knitted with only the first yarn. The yarn that is seen as gray in the plating area P is the first yarn, and the elastic yarn G is seen only in the periphery of the plating area P. This is because when the knitted sock is removed from the flat knitting machine, the elastic yarn G having a high stretch ratio contracts and is similarly hidden inside the plated elastic yarn. Although it is not desirable that the elastic yarn G directly contact the skin, the elastic yarn G does not contact the skin by covering the elastic yarn G.
Fig. 5 and 6 show a part of the sock after plating knitting with a thick yarn having a low stretch ratio as a plating yarn, the thick yarn being a main yarn of the elastic yarn. The right triangular portion (portion where the mesh exists) in fig. 5 is a tightening portion using the elastic yarn and the plating yarn, and is a position of the arch of the foot, and both the elastic yarn and the plating yarn are not visible from the front of the sock. Since plating is a thick and hard-to-stretch yarn, the knitted fabric is thick and has high cushioning properties. Fig. 6 shows the inside of the sock, in which the elastic yarn is contracted and hardly visible, and the plating is raised in a loop-like knitted fabric.
The direction of the loop approaching can be any one of left and right directions, and the directions do not need to be consistent. However, since the arrangement of the holes and the overlapping stitches in the mesh structure changes the aesthetic appearance of the knitted fabric, it is preferable to arrange them regularly. When forming the overlapping stitch, the second yarn can be reliably hidden by arranging the overlapping stitch on the reverse side of the overlapped stitch.
The knitted fabric to be knitted is not limited to tubular knitted fabrics such as socks, gloves, body protectors, and uppers, and can be used as a cover of a chair having a high cushioning property in a flat shape. 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.
