Definitions

• the present invention relates to a spliced yarn splicing method in which thin fibers are bundled by spinning and a knitted fabric including the spliced yarn.
• Fig. 4 shows a state in which the ends of different yarns are joined by forming a knot as a conventional method of yarn joining. That is, the yarn 1 and the yarn 2 are joined by forming a knot 3 at the end. The ends la and 2a of the yarns 1 and 2 protrude from the knot 3. The tip la, 2 a can be cut and shortened after the knot 3 is formed, but it is difficult to completely eliminate it.
• a knotter device is used to form the knot 3.
• the method of forming and joining the knot 3 is also widely used for ropes that do not use spinning yarn.
• Fig. 5 shows the joining state of the yarns 1 and 2 by the method of splicing without forming a knot.
• This splicing method is effective when the yarns 1 and 2 are spun yarns, and the twists of the fibers on the tip side of the two opposing yarns 1 and 2 are loosened and the forces are entangled with each other.

• the processing of the envelope 5 becomes a problem. If the envelope 5 appears to protrude outside the knitted fabric, the appearance is impaired.
• the envelope part 5 is incorporated in the knitted fabric, a part corresponding to three knitting yarns is generated together with the envelope part 5. If the envelope portion 5 can be taken into the knitted fabric and concealed, the yarns 1 and 2 connected by the envelope portion 5 can be switched without being mixed, and a pattern having a good appearance can be knitted. However, it is difficult to handle the envelope 5 well. Furthermore, in the methods shown in FIGS. 5 and 6, since different yarns 1 and 2 are entangled, if the properties of the yarns 1 and 2 are different, it may be necessary to consider the combination.

• Such knitting of the color patterns 21, 22, and 23 can be performed by using different yarn supplying members for knitting yarns having different colors. Further, different yarn supplying members are used for the patterns 20a, 20b of the knitted fabric 20 divided by the color patterns 21, 22, 23. did In order to knit the patterns 21, 22 and 23 and the patterns 20a and 20b of the knitted fabric 20, five yarn feeding members are used.

Since the knot is not formed, it is possible to eliminate the possibility that the knitting yarn will become a resistance at the time of forming the stitch, or may be caught by the knitting needle and cause yarn breakage.
