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.
- an “I” shaped seam 4 is formed.
- the ends la and 2a of the yarns 1 and 2 remain slightly untwisted.
- Yarn splicing by the formation of the seam 4 can be performed quickly by jetting compressed air or the like (see, for example, Japanese Patent Publication No. 60-39767).
- FIG. 6 shows another method of splicing without forming a knot.
- This method is also thread 1, 2 This is effective when is a spun yarn.
- the yarns 1 and 2 are arranged with their tips directed in the same direction, and the tips are entangled to form an envelope portion 5 (see, for example, JP-A-2004-27463).
- the envelope part 5 by this method is “T” -shaped in appearance, and the part corresponding to the vertical line of the “ ⁇ ” character is radially outward of the part corresponding to the horizontal line of the “ ⁇ ” character by the yarns 1 and 2. Protrusively.
- the tips la, 2a of the yarns 1, 2 protrude in an untwisted state.
- Japanese Laid-Open Patent Publication No. 2004-149941 also uses this yarn splicing method! RU
- a knot 3 as shown in Fig. 4 is formed by a knotter device or the like and applied to a knitting yarn, the knot 3 has a diameter several times the thickness of the yarns 1 and 2, so the stitch There is a risk of resistance during formation or catching on the knitting needle and causing thread breakage.
- the seam 4 formed by intertwining two yarns 1 and 2 as shown in Fig. 5 if the colors of the yarns 1 and 2 are different, color mixing occurs and the color boundary becomes unclear.
- color mixing occurs at the joint 4 where the yarns 1 and 2 of different colors are joined, an unintended color portion will be generated and the appearance of the knitted fabric will be impaired.
- 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.
- An object of the present invention is to provide a spun yarn splicing method and a knitting including a spliced yarn that do not form a knot at the time of splicing, eliminate color mixing and protrusion of the end yarn, and improve quality and appearance. Is to provide the ground.

- FIG. 6 is a simplified diagram showing another method for piecing without forming a knot according to the prior art.
- 1A and 1B show an embodiment of the present invention and show the shape of the joint portion to be spliced. Show.
- the ends of the two spun yarns 11 and 12 are joined together.
- the spun yarns 11 and 12 are opposed to each other in opposite directions so that the front end sides 11a and 12a are abutted.
- the front end sides 11a and 12a of the spun yarns 11 and 12 are turned back to the base end side.
- the folded portions l ib and 12b are joined and joined together. That is, the folded portion 12b of the spun yarn 12 passes through the folded portion 1 lb of the spun yarn 11, and the folded portion l ib of the spun yarn 11 passes through the folded portion 12b of the spun yarn 12.
- the front ends 11a and 12a of the spun yarns 11 and 12 are untwisted and joined by being entangled with the base end sides 11c and 12c of the folded portions l ib and 12b, that is, the two spun yarns 11 and 12
- the spun yarns 11 and 12 are folded back in a so-called "J" shape on the leading ends 11a and 12a.
- the leading ends 1 la and 12a of the spun yarns 11 and 12 are intertwined with the proximal ends 11c and 12c of the folded portions l ib and 12b to join them.
- the ends 11a and 12a of the spun yarns 11 and 12 are folded back and faced so that the folded portions l ib and 12b are coupled to each other, the ends can be subjected to yarn splicing.
- the leading ends 11a and 12a of the spun yarns 11 and 12 are intertwined with the base end sides 11c and 12c of the folded portions l ib and 12b and joined to each other, so that the leading ends 11a and 12a of the spun yarns 11 and 12 are
- the fold portions l ib and 12b are intertwined with the base end sides 11c and 12c of the turn-back portions l ib and 12b so that the yarn can be reliably spliced by entanglement with itself.
- knots are not formed, it is possible to suppress the possibility that the knitting yarn will become a resistance during formation of the stitch or may be caught on the knitting needle and cause yarn breakage. Since the yarns are connected to each other at the turn-back portions l ib and 12b, the quality and appearance can be improved without being mixed even if the colors are different. Since the distal end sides 11a and 12a are intertwined with the proximal end sides 11c and 12c, the leading edge lid and 12d can be suppressed to the extent that they become fluffy.
- FIG. 2 shows a simplified knitted fabric 20 that is knitted while forming the spliced portion 10 shown in FIGS. 1A and 1B.
- the knitted fabric 20 is provided with color patterns 21, 22, 23 force S formed by intarsia knitting or the like. For this reason, it is necessary to switch between the knitting yarn for knitting the pattern of the knitted fabric 20 and the knitting yarn for knitting the color patterns 21, 22, 23.
- 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.
- the knitting patterns 21, 22, 23 are knitted by switching a plurality of knitting yarns with one yarn feeding member.
- the boundary of the color patterns 21, 22, 2 3 can be joined by the yarn joining part 10.
- the color can be switched without color mixing.
- FIG. 3 shows a schematic procedure for forming the spliced portion 10 as shown in FIGS. 1A and 1B.
- the piecing is performed in the supply path.
- the length of knitting yarn consumed by knitting of the knitted fabric 20 is calculated based on data such as loop length, based on knitting data. It is possible to measure the amount of knitting yarn supplied.
- start step sO force piecing If the knitting yarn supplied before piecing still remains, cut it.
- step si the two spun yarns are opposed to each other so that the leading end side of the knitting yarn to be spliced is opposed to the tail end of the cut knitting yarn.
- step s2 the ends of the two spun yarns are folded back and the folded portions are joined together.
- the joint is untwisted with a compressed air flow and enveloped.
- a device having the same principle as the device can also be used. However, it is necessary to join on both sides and make the set to the equipment different.
- step s3 the distal end side and the proximal end side of the folded portion are joined, and the procedure is terminated in step s4.
- step s2 the ends 11a and 12a of the two spun yarns 11 and 12 are folded and joined simultaneously, and in step s3, the ends 11a and 12a are joined to the base ends 11c and 12c at the same time.
- the leading end side 11a of one thread 11 is first joined to the proximal end side 11c of the folded portion l ib. Since the folded portion l ib has a ring shape, the distal end side 12a of the other thread 12 is inserted into the annular shape to fold back to form a folded portion 12b, and the distal end side 12a serves as the base end of the folded portion 12b.
- the side 12c should be joined together. Since one side is joined to each other, JP 2004-149941 A, JP-B 60-397 This can be achieved by directly using the devices disclosed in 67 and JP 2004-27463.
- the two spun yarns 11 and 12 that are switched by forming the yarn splicing portion 10 can have an effect that the boundary is clear if the appearance is different such as color and other appearance.
- the boundary between the knitted fabric that changes the thickness of the knitting yarn and the knitted fabric that changes the fluff of the knitting yarn, etc. It is possible to perform knitting with improved quality and appearance by performing piecing without forming a knot.
- the switching of the knitting yarn is not limited by the number of yarn supply members that can be used, etc., so knitting a knitted fabric with an increased commercial value by using or separating many colors. You can also.
- the ends of the spun yarns are folded back so that the folded portions are opposed to each other. Since the tip of the tangle is entangled with the base end side of the folded portion and entangled with itself, the yarn can be reliably spliced regardless of the partner to be joined. Even opponents with different material properties or thickness can be easily inherited. 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. Since the yarns are connected to each other at the folded portion, they do not mix even if the colors are different!
- two spun yarns having different appearances such as color, thickness, and shape can be joined without forming knots and mixed color portions.
- two spun yarns can be spliced quickly and efficiently.
- Color patterns can be knitted by switching a plurality of knitting yarns with the yarn supplying member.
- Knitted fabric in a knitted fabric that forms a colored pattern, a knot and a mixed color part are not formed in the knitting of the pattern switching part, and the piecing is performed, and the quality and appearance are improved. Knitted fabric can be knitted.
