Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a tape yarn used as a warp, a weft, a knitting yarn, a pile yarn, an embroidery yarn, a handicraft yarn, a decorative yarn, etc. It is related to.

[Conventional technology]

Tape yarns used for warps, wefts, knitting yarns, etc. include plastic films cut into 2-511A widths and narrow woven fabrics with a weaving width of 2-5A, and these are also called ribbon yarns.

[Problem that the invention seeks to solve]

The commonly used tape yarn has both edges that are dense and continuous in a straight line, does not have the same fuzz that spun yarn has, and the woven or knitted fabrics made from it do not have a soft texture.

In particular, plastic tape yarns do not absorb moisture at all, and the fabrics made from them are completely unsuitable for clothing, and are used exclusively as industrial materials, such as the base fabric of tufted cloth, bag fabrics such as tonglos, or packaging materials.

On the other hand, although woven tape yarn absorbs moisture, it is extremely expensive because it is produced by driving the weft yarns with a single shuttle like general wide woven fabrics, and the resulting fabric has a poor texture as mentioned above. Woven tape yarn is coarse and hard, and although it is used for handicraft threads and embroidery threads, it is unsuitable for general clothing.

Of course, it is possible to cut a non-woven fabric into a tape shape according to the manufacturing method of plastic tape yarn and make a tape yarn with moisture absorption properties at a low cost, but the tape yarn made of the non-woven fabric obtained in this way has a weak tensile strength and is not suitable for plastic tape. It is not possible to make and weave with strong tension similar to that of yarn.

(Purpose of the Invention) Therefore, the present invention provides a plastic tape yarn that can be knitted and woven using a knitting machine or a loom that causes yarn breakage, has hygroscopicity similar to woven tape yarn, and has the same tensile strength as spun yarn. The purpose of the present invention is to obtain a tape yarn having strength, abrasion resistance, and excellent tactile feel at a low cost.

[Structure of the invention]

That is, the tape yarn 15 according to the present invention has a sewing thread 12 along the length direction of the central part of the tape 14 obtained by cutting the sheet 11.
This feature is characterized in that a seam 13 is formed by sewing.

The sheet 11 is made of paper such as woven fabric, knitted fabric, non-woven fabric, or plastic film. If the sheet 11 is a woven fabric, it is also possible to add seams 13 in the diagonal direction of the warp (weft) so that all the warp threads 16 and weft threads 17 intersect at the seam 13. In that case, the seams 12 can be glued It is also possible to adhere the tape 14 and the seam 13 using the sewing thread 12 which carries the agent 34 or is made of heat-fusible fibers 27, or the left and right edges 18 of the tape 14 are raised at the same time as cutting. You can also do that.

In order to raise the left and right edges 18 of the tape 14 at the same time as cutting, a large number of sewing threads 12 are simultaneously sewn into the seams 1-11 using a quilting machine or a knitting machine such as Arakune or Marimo. The seams 13 are made parallel, and a cutter and a napping tool are applied between the seams 13 and 13', 13' and 13'', etc., thereby forming the edge 18. A large number of raised tape yarns 15 can be made simultaneously.

When sewing heat-fusible thread, it is heated in front of the cutter to fuse it to the sheet.

As shown in the embodiment, two or a combination of two or more sewing threads, the heat-fusible thread 27 and the non-heat-fusible thread 12, can also be used.

〔Effect of the invention〕

As mentioned above, even if the tape 14 itself is made of nonwoven fabric or paper with low tensile strength, it is reinforced by the seams 13 that are continuous in the length direction, and its both edges 18 are raised, so that it can be used as a conventional tape. Even if the texture is softer than that of yarn, and the seam 13 is chain stitched which easily frays, the tape 1
Since the stitches 13 are glued to the tape 14, the sewing thread 12 will not be continuously pulled out of the tape due to fraying of the stitches. It is now possible to sew using chain stitch without using the sewing machine.

In this way, by chain stitching without a bobbin thread, the spaces between stitches 13 and 13', 13' and 13'', etc. are narrowed, and multiple threads of tape yarn 15 are continuous at the same time. You can make it.

As described above, according to the present invention, it has excellent tensile strength and abrasion resistance,
This is advantageous because tape yarn, which is fluffy like spun yarn, has a soft texture, and is hygroscopic, can be obtained efficiently and at a low cost.

〔Example〕

FIG. 1 shows a sheet 1 being sent out at a constant speed to a delivery roll 19.
A large number of sewing threads 12 are sewn onto the thread 1 with a large number of needles 20 to form a large number of stitches 13, and these stitches 13 and 13'
, 13' and 13'1, . The mass production process is illustrated, and the sewing thread 12 is chain-stitched.

2 to 5 illustrate the chain stitching process, in which a pair of hooks 26 and 25 are reciprocating back and forth toward the needle operating line o-0'.

When the needle 20 is inserted into the sheet 11 and pulled back, the loop 24 created by the sewing thread 12 is caught by the hook 26 (Fig. 3), and when the needle 20 rises further above the hook 26, The temporary locking hook 25 is inserted into the loop 24 that is locked by the hook 26 (FIG. 4), and as the hook 26 retreats, the receiver picks up the loop 24 that has come off from it and moves further forward.
Lay down parallel to the seat 11 (Fig. 5).

When the needle 20 is pulled out, the sheet 11 moves in the direction shown by the arrow, so the next needle 20 to be inserted passes through the fallen loop 24 and creates a new loop 24' again. Figure 2).

At the time when the needle 20 passes through the previous loop 24, the temporary locking hook 25 is in the backward position S3 (Fig. 2), and as the needle 20 moves backward, the previous loop 24 comes off from the temporary locking hook 25, and a chain stitch is formed. A continuous seam 13 is created (FIG. 3), and thus a continuous seam 13 is sewn.

Here, in addition to the sewing thread 12 to be chain-stitched, a heat-fusible thread 27 is used.
is used.

This heat-fusible yarn 27 is pulled out from the shift guide 28 of the shifter 35, which vibrates from side to side every time the needle 20 approaches the needle 20 and is pulled out from the sheet 11, and thus sticks the needle 20 into the sheet 11. 12 threads per
The sheet 11 is pressed down and continues along the seam 13 so as to crawl along the surface of the sheet 11.

The sheet 11 with the seams 13 passes between a roll 29 whose surface is wrapped with a heat insulating material and a heater 30;
At this time, the heat-fusible thread 27 melts, so that the sheet 11 and the sewing thread 12 are bonded together by the heat-fusible thread 27.

Incidentally, the heater 30 automatically rises and separates from the seat 11 when the seat 11 stops.

A large number of sharp protrusions 32 are protruded from the rear side surface of the cutting edge 31 of the movable blade 21, and when the movable blade 21 moves up and down, these protrusions 32 cut the edge 1 of the cut tape 14.
8 is rubbed and raised, thus creating a tape yarn 15 that firmly adheres to the seam 13 and tape 14 and has fluffy edges 18 on both ends.

In this embodiment, a two-blade cutting device consisting of a movable blade 21 and a fixed blade 22 is used to cut the sheet 11, but a circle cutter can also be used instead. In that case, move the edge of the circle cutter closer to the protrusion 32.
to protrude. A rotating circular saw or thin grinder can also be used as a cutting device, in which case the protrusion 32
It is not necessary to provide a special protrusion.

Further, in order to adhere the sheet 11 and the seam 13, a normal thread 27' is used instead of the heat-fusible thread 27, adhesive 34 is put into the shifter 35, and the thread 27' is bonded to the seam 13. It is also possible to draw the thread 27' through the adhesive bath 33 and make the thread 27' carry the adhesive 34 and apply it between the sheet 11 and the seam 13, thereby bonding the sheet 11 and the seam 13 together.
