Abstract

PROBLEM TO BE SOLVED: To provide a method for felling the end of a knitted fabric, enabling to form the knitted fabric end excellent in elasticity without deteriorating the tightness of the felled end. SOLUTION: This method for felling the end of a knitted fabric comprises producing the knitted fabric by the use of a flat knitting machine having at least a pair of front and back needle beds whose one or both can laterally be slid, and subsequently subjecting the loops 7a-7d of the final course forming the final end of the knitted fabric to a run-proof treatment. The run-proof treatment comprises feeding knitting yarns 10a-10b to form the loops 9a, 9b of the edge stitch portion followed to the loops 7a-7b of the final course, superposing the loops 9a, 9b of the formed edge stitch portion on the loops 7a-7d of the adjacent final course, and subsequently repeatedly subjecting the superposed loops to knitting treatments from one end of the final coerces to the other end to fix the loops of the final course. Each of the knitting treatments comprises feeding the fed yarns 10a-10d to needles for catching the superposed loops to form the loops 9a, 9b of the edge stitch portion. Therein, after the knitting yarns 10a-10d are wound on the loops 7a-7d of the final course placed at the front position in the felling direction, the loops 9a, 9b of the edge stitch portion are formed.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of knitting a knitted fabric using a flat knitting machine and supplying a knitting yarn to the knitted fabric following a loop positioned at the end of the final course when the knitting yarn is unraveled. Forming a loop, superimposing the formed loop with an adjacent loop, supplying a knitting yarn to the superimposed loop to form a subsequent loop of the edge stitch portion, and knitting from one end to the other end of the final course The present invention relates to a bind-off processing method for preventing the loop of the final course from being unraveled by repeatedly performing the looping process.

[0002]

2. Description of the Related Art When knitting a knitted fabric with a flat knitting machine, an edge stitch portion for connecting loops of a final course is formed by knitting on the flat knitting machine to prevent unraveling, so that knitting is completed. Various bind-off treatment methods for simplifying a sewing operation have been studied.
The knitting of a knitted fabric in a flat knitting machine, for example, in the case of knitting the front part of a sweater, knitting is started from a hem rubber portion, knitting is advanced from a body portion to a shoulder direction, and finally a collar neck It is common to perform knitting in the direction of forming the part. When knitting is performed in such an order, the end of the neck becomes the end of the knitted fabric. Openings such as the neck portion are often stretched by applying force when worn, and therefore are generally knitted with a knitted structure having excellent elasticity such as a rib knitted structure.

In the above bind-off processing method, the knitting in which the loop of the edge stitch portion is overlapped with the final course to form the loop of the next course is repeated, so that the edge stitch portion is formed in a chain stitch shape that is continuous in the arrangement direction of the course. It is formed. However, in general, a knitted fabric is excellent in elasticity in a wale arrangement direction (horizontal direction toward the knitting direction), but poor in elasticity in a course arrangement direction (vertical direction toward the knitting direction). Therefore, when the final course is bind-off processed by the conventional bind-off processing method, the elongation in the arrangement direction of the wale at the end of the knitted fabric is limited by the loop of the edge stitch portion connecting the loops of the final course, and when worn, There is a problem that the knitting yarn may be cut when a force is applied to the neck portion, and that the elasticity of the neck portion is impaired. In order to solve this problem, measures have been taken to improve the elasticity, such as forming the loop of the edge stitch portion as a loop having a longer loop length than a normal loop, but this method has improved the elasticity. Also, there is a problem that the edge stitch portion remains extended and the end of the knitted fabric is no longer tightened.

[0004]

SUMMARY OF THE INVENTION The present invention solves the problems of the above-mentioned conventional bind-off processing method, and provides a stretchable material suitable for preventing unraveling at places where elongation such as a neck portion is required. An excellent new bind-off treatment method is disclosed.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a method for treating a bind-off with excellent elasticity, comprising at least one pair of front and rear needle beds, one or both of them. The knitting fabric is knitted using a flat knitting machine in which the needle bed is configured to be slidable left and right, and the knitting yarn is supplied and the final course Form a loop of the edge stitch part following the loop of
The formed loop of the edge stitch is overlapped with the loop of the adjacent final course, and a knitting yarn is supplied to a needle that locks the overlapped loop to form a loop of the subsequent edge stitch, thereby forming one end of the final course. In the bind-off processing method of unraveling the loop of the final course by repeatedly performing from the side to the other end side, the knitting yarn is wound around the loop of the final course located forward in the progress direction of the bind-off processing. The loop of the edge stitch part is formed from the above. Further, the bind-off treatment method excellent in elasticity of the present invention,
Moving the knitting yarn used for forming the loop of the edge stitch portion beyond the loop located forward in the advance direction of the bind-off processing, the loop of the final course located forward in the advance direction of the bind-off processing By transferring the knitting yarn to the needle of the opposing needle bed, the knitting yarn is held down by the transferred loop, and the knitting yarn held by the transferred loop is held by the loop of the edge stitch portion. One of the features of the present invention is to include a step of forming a loop of the next edge stitch portion by supplying the same to the needle which is being used. According to the above configuration, the loop of the edge stitch portion formed subsequent to the final course is formed after being wound around the loop located forward in the progress direction of the bind-off processing of the final course.
As a result, when a force is applied to the end of the knitted fabric, the knitting yarn wound around the final course is absorbed by the loops of the edge stitches, and the loops of the edge stitches are extended together with the final course. And the elongation of the knitted fabric end is improved.

FIG. 4 is a loop diagram showing locations. In the knitting course diagrams of FIGS. 2 to 4, uppercase letters A to J of the alphabet represent needles of the front bed, and lowercase letters a to j of the alphabet represent needles of the rear bed. In the figure, the left and right arrows indicate the direction in which the yarn feeder moves, and the up and down arrows indicate the loop transfer direction.

The knitting of the front body 1 of the sweater shown in FIG. 1 starts from the hem rubber portion 2, and the body portion 3 to the shoulder portions 4,
After the formation of the collar 5, the collar 6 is formed, and the loops 7a, 7b, 7c, 7d,... Of the final course of the collar 6 are bound off. The course 2-1 in FIG. 2 shows a state in which the knitting of the collar 6 is completed up to the point where the binding processing is started, and loops 7a, 7b, 7c, 7 of the final course of the collar 6 are shown.
are locked to the needles B to I. The yarn feeder 8 used for the bind-off processing is in a state of stopping on the left side of the needle B after forming the last loop with the needle B of the front bed. In the present embodiment, the bind-off processing is performed from the needle B to the needle I, and the direction of the bind-off processing used in the following description means the direction from the needle B to the needle I. A loop of an edge stitch portion that is continuous in this direction is formed. In the course 2-2, the loop 7a of the needle B of the front bed, which is the side end of the knitting area, is transferred to the needle b of the rear bed, and the loop 7a locked by the needle b and the loop 7a locked by the adjacent needle B Loop 7b is distributed to the needles of the front and rear needle beds. In the course 2-3, the yarn feeder 8 is moved to the right, which is the direction of the bind-off processing, to lock the knitting yarn on the needle A of the front bed, and to cross the loop distributed to the needles of the front and rear needle beds. And the knitting yarn extending from the yarn feeder 8 to the knitted fabric passes through the loop that has been sorted back and forth. Next, in course 2-4, the loop 7a locked to the needle b of the rear bed is transferred to the needle B of the front bed, and the loop 7b locked to the needle C of the front bed is changed to the needle c of the rear bed.
Transfer to As a result, the knitting yarn passed through the front and rear loops is transferred to the needle on the opposing needle bed with the front and rear loops interposed therebetween. Next, in the course 2-5, the yarn feeder 8 is moved to the left to supply the yarn to the needle B of the front bed, and the loop 9a of the edge stitch portion following the loop 7a of the final course.
a is formed. Then, in the course 2-6, the newly formed loop 9a is transferred to the needle b of the rear bed, and the course 2-7
Then, after the rear bed is racked to the right by one needle, the loop 9a locked to the needle b of the rear needle bed is transferred to the needle C of the front bed.

In the course 3-1 of FIG. 3, the yarn feeder 8 is moved in the direction of the bind-off processing, the yarn is fed to the needle B of the front bed to lock the knitting yarn, and the needle c of the rear bed is connected to the front c. The needle is passed through the loop which is distributed to the needles of the front and rear needle beds by the needle D of the bed. In the course 3-2, the loop 7b locked to the needle c of the rear bed is transferred to the needle C of the front bed, and overlaps with the loop 9a of the edge stitch portion locked to the needle C of the front bed. Then, the loop 7c locked to the needle D of the front bed is transferred to the needle d of the rear bed, and is transferred to the needle on the opposite needle bed passing above the knitting yarn. In the course 3-3, the yarn feeder 8 is moved leftward to feed the needle C of the front bed to form a loop 9b of the edge stitch portion. As a result, the number of loops locked to the needle is reduced by one from the state shown in the course 2-1.

Next, in the course 3-4, the newly formed loop 9b is transferred to the needle c of the rear bed. In the course 3-5, the rear bed is moved to the right by one needle, and then the needle of the front bed is moved. D
Transfer to In the course 3-6, the yarn feeder 8 is moved in the direction of progress of the bind-off processing, the knitting yarn is locked on the needle C of the front bed, and the yarn feeder 8 is passed over the loop distributed to the needles of the front and rear needle beds. In 3-7, the needle d on the rear bed
The loop 7c locked to the needle D of the front bed is transferred to the loop 9b of the edge stitch portion, and the loop 7d locked to the needle E of the front bed is aligned with the needle e of the rear bed. Transfer. Thereafter, the knitting shown in courses 3-3 to 3-7 is referred to as loops 7a, 7b, 7c of the final course of the knitted fabric.
7d... Are repeatedly performed in the direction of progress of the bind-off processing, so that the loop of the final course at the knitted fabric end portion is bind-off processed by the loop of the edge stitch part. Course 2-1
At the time when the binding processing of all the loops locked to the needles B to I of the front bed is completed, the courses 2-3, 3-1 and 3 as shown in the course 4-1 in FIG. -6
Thus, the knitting yarn locked by, for example, is locked by the needles A to H of the front bed. Then, in course 4-2, the bind-off processing is completed by removing the loop from the needles A to H of the front bed.

FIG. 4 shows a loop diagram of a bind-off processing portion of a knitted fabric subjected to bind-off processing in accordance with the knitting course diagram. As shown in FIG. 4, loops 9a, 9b... Of the edge stitches formed in the process of the bind-off processing are loops 7c of the final course.
After winding around 7d, loops 9b at the next edge stitch portion are formed. Therefore, when a force is applied to the end of the knitted fabric and the final course is stretched, the knitting yarns 10a, 10b,
As the loops 9a, 9b,... Are extended and the loops 9a, 9b,. Further, the knitting yarn wound on the adjacent loop is pulled back by the force contracting in the horizontal direction of the loop of the final course when no force is applied to the knitted fabric terminal end. Therefore, the tightness of the knitted fabric terminal portion is not impaired. As described above, the knitted fabric subjected to the bind-off processing by the bind-off processing method of the present invention has the knitted fabric termination portion tightened while no force is applied to the knitted fabric termination portion. When a force is applied in the stretching direction, the knitting yarn wound around the loop at the end of the knitted fabric is drawn into the loop at the edge stitch portion, the loop is extended, and the extension at the end of the knitted fabric is increased.

In the above-described embodiment, course 2
When the yarn feeder 8 is moved rightward in the course 3, the course 3-1 and the course 3-6, the knitting yarn is locked to the empty needle in the course 3-1. After locking the final course, the loop of the final course can be wound, thereby increasing the knitting yarn length of the part where the loop of the final course is wound, and forming a knitted fabric end portion with excellent elongation of the knitted fabric end portion. . In addition, since the knitted fabric is held in a state locked by the knitting needles in the entire knitting area during the bind-off processing, it is compared with the case where the bind-off processing is performed while the knitted fabric is brushed off in the area where the bind-off processing is completed. It is easy to adjust the winding tension of the knitted fabric, and the size of the loop at the edge stitch portion can be made uniform. However, it is not always necessary to lock the knitting yarn to the empty needle as shown in the above-described embodiment, and the above-described courses 2-3, 3-1 and
Only the movement of the yarn feeder 8 may be performed in the course 3-6.

In the above-described embodiment, when the knitting yarn is wound around the loop, the loop is distributed to the needles on both front and rear needle beds, and then the loop is fed over the distributed loop. The knitting yarn is wound around the loop by moving the yarn opening and transferring both loops to the needle on the opposite needle bed. For example, the yarn feeding opening is moved rightward in course 2-1. Then, the loop of the needle C of the front bed is transferred to the needle c of the rear bed, and then the yarn feeder is moved to the left to feed the needle B of the front bed to form an edge stitch. It is also possible to wind a knitting yarn around the loop of the final course. As described above, the method of winding the knitting yarn around the loop of the final course is not limited to the method described in the above embodiment.

Further, in the above-described embodiment, the case where the final course of the neck portion knitted with the flat knitting structure is subjected to the bind-off processing is described as an example. You can also. In this case, since the loop of the final course knitted with the rib knitting structure draws the loops of the final course with a stronger contraction force than the case of knitting with the flat knitting structure, the loop of the final course knitted with the flat knitting structure is also increased. Thus, it is possible to form a tight knitted fabric terminal portion. Further, in the present embodiment, the bind-off processing is performed using the knitting yarn used for knitting the front body 1 of the sweater, but the bind-off processing is different from the knitting yarn used for knitting the front body 1 of the sweater. It may be performed using a knitting yarn. Further, in the above-described embodiment, when the knitting yarn forming the loop of the edge stitch portion is wound around the loop of the final course, the loop immediately adjacent to the loop in which the loop of the edge stitch portion is newly formed is formed. It is wound around, but it is not necessary to wind it on the next loop immediately, it is possible to skip the adjacent loop and wind it on the next loop, or wind it on multiple loops including the adjacent loop And preferably a second loop including a first loop adjacent in the direction of progress of the bind-off processing or a loop further adjacent thereto. In the above-described embodiment, the case where the bind-off processing is performed on the collar neck, where the final course is the final course of the entire knitted fabric, has been described as an example. If it is the loop of the last course, the bind-off processing can be performed.

[0015]

As described above, in the bind-off processing method of the present invention having excellent stretchability, when bind-off processing is performed on the loop of the final course, the knitting yarn forming the loop of the edge stitch portion is used to form the adjacent wales. After being wound around a loop positioned forward in the progress direction of the bind-off processing in the loop of the final course, a loop of an edge stitch portion is formed. Therefore,
When a force is applied to the end of the knitted fabric, the loop of the edge stitch portion can be extended by the knitting yarn wound around the loop of the adjacent final course, so that the loop of the edge stitch portion can be extended together with the loop of the final course. The loop can also extend in the direction in which the wale is arranged, and the extension of the knitted fabric end portion increases. When no force is applied to the end of the knitted fabric, the loops of the edge stitches are attracted to each other due to the contractility of the loop of the final course, so that the end of the knitted fabric is not tightened.
