[Field of the Invention]
TECHNICAL FIELD The present invention relates to a fluff yarn used as a raw material for making a knitted fabric or a woven fabric, and more particularly to a warp knitted fluff yarn having elasticity obtained by cutting a warp knitted fabric.
[0002]
[Prior art]
When making fabrics, in addition to producing knitted fabrics and fabrics using synthetic filament yarns such as polyester and spun yarns such as cotton, surface effects such as fluffing, soft feeling, unevenness, etc. I have a feeling.
Thereby, a knitted fabric or a woven fabric having functions such as unique function and heat retention can be obtained.
[0003]
Examples of the fluff yarn include chenille yarn obtained by cutting once a woven fabric or warp knitted fabric.
Above all, warp knitted wool yarn obtained by cutting warp knitted fabric such as tricot is not only good texture, delicate and fashionable, but also warp knitted wool yarn itself. This has the advantage that the productivity of the product is extremely improved, and is often used.
[0004]
As for the warp knitted wool yarn, a method of knitting a wide warp knitted fabric with a tricot machine or a raschel machine and cutting the knitted fabric on the machine is the mainstream.
That is, as shown in FIG. 1, chain knitting S is knitted at an appropriate interval, and at the same time, these chain knitting S are connected by the connecting yarn R to obtain a warp knitted fabric T.
And this warp knitted fabric T is cut | disconnected by the cutter CT installed on the machine.
One cutter CT is installed between the chain stitch S and the chain stitch S, and the warp knitted fabric T, which is knitted in the direction of arrow A, is cut and separated in the wale W direction to obtain a number of warp knitted wool yarns. TY is manufactured at the same time.
The connecting yarn R includes a connecting portion K that connects the connecting yarn R to the chain stitch S, and a spanning portion B that is spanned between the chain stitches S and S, and includes the connecting portion K and the spanning portion B. As the connected tissue RK to be performed, there is a knitted tissue or the like shown in FIG. 3 in addition to the insertion tissue shown in FIG. 1 as an example.
[0005]
Further, as the material of the warp knitted wool yarn TY, synthetic yarns such as nylon yarn and polyester yarn for the chain knitting S, wooly nylon yarn and wooly polyester yarn subjected to wooly processing are mainly used.
Further, as the connecting yarn R, silk or the like is mainly used in addition to rayon yarn, acetate yarn, acrylic yarn, and this becomes the fluff yarn F.
[0006]
[Problems to be solved by the invention]
As described above, the manufacturing means and the materials used for the conventional warp knitted wool yarn TY have been described. Recently, however, there is a strong demand for imparting a stretchable function to the warp knitted wool yarn TY. Here, normally, in a wide warp knitted fabric, an elastic yarn such as a polyurethane yarn is used as means for imparting stretchability.
Among them, a method using a covered yarn in which an elastic yarn is used as a core yarn and a cover yarn such as a wooly nylon yarn is wound around the elastic yarn is mainly used.
[0007]
As shown in FIG. 5, the covered yarn CY takes a form in which a cover yarn Y2 is wound around a core yarn Y1 in a spiral shape.
Therefore, when tension is applied to the covered yarn CY, it can be expanded and contracted within the range until the spiral of the cover yarn Y2 is fully extended.
If the number of turns of the cover yarn Y2 is increased, the winding length becomes longer, so the range of extension becomes larger, and the number of turns becomes smaller if the number of turns is small.
Thus, the covered yarn CY can control the range of elongation by the number of turns of the cover yarn Y2.
By using this covered yarn CY for the chain knitting S, it is possible to obtain a chain knitting S that is freely stretchable and that can suppress the elongation within a certain range.
[0008]
However, when a wide warp knitted fabric T is knitted on the chain knitting S using the covered yarn CY, and this is cut to obtain a warp knitted fluff yarn TY, many problems arise.
When an insertion tissue is used for the connecting portion K, as shown in FIG. 1, since the cutter CT hits the spanning portion B of the connecting yarn R in a state of being almost orthogonal as shown in FIG. It has the advantage of being done.
However, when such warp knitted fluff yarn TY is tensioned in use, the chain stitch S is stretched to form a gap G as shown in FIG. 2, and the fluff yarn F (the connected yarn is cut) is formed. The gripping force is reduced, fluffing occurs, and the product has a defect.
[0009]
Therefore, in order to prevent fluff coming off, as shown in FIG. 3, if the warp knitted fluff yarn TY is manufactured using a knitted structure in the connecting portion K, the connecting portion K becomes a loop KL as shown in FIG. And is knitted into the chain stitch S.
Therefore, there is an advantage that no fluff is generated even if the chain knitting S is stretched and stretched during use.
However, when the knitted structure KL is used for the connecting portion K, as can be understood from FIG. 3, the connecting yarn R inevitably has a chain knitting S from one chain knitting S due to the principle of warp knitting. As a result, the connecting portion R of the connecting yarn R is slanted against the cutter CT.
As a result, when cutting, there is a problem that a slip phenomenon occurs between the connecting yarn R and the cutter CT, the cut portions are shifted, and the fluff lengths are uneven, or the chain stitch itself is sometimes cut.
[0010]
By the way, if the chain knitting S is not a large stretchable yarn such as polyurethane yarn but nylon or polyester, each chain knitting S is densely knitted and has little stretchability, and the knitting machine winding device Since it is strongly pulled downward, even if the connecting part K is a knitted structure KL, the bridging part B is firmly fixed by the chain stitches S, S on both sides, and the cut portion due to the sliding phenomenon at the time of cutting is fixed. The shift does not occur so much and does not become a big problem.
However, when the chain knitting S is formed by the stretchable covered yarn CY (see FIG. 5), the chain knitting S is not stretched and stabilized. In particular, when the sharpness of the cutter CT deteriorates even a little, the cutting portion is not fixed. Therefore, the problem that the fluff length becomes uneven occurs.
[0011]
As described above, when using the covered yarn CY to obtain the warp knitted fluff yarn TY having elasticity, there are problems when the connecting yarn R is cut, fluff length irregularities, and fluff problems. There were many issues to be solved, and we could not provide a satisfactory product for consumers.
[0012]
[Means for Solving the Problems]
Therefore, in the present invention, in order to solve the above problems, when connecting the chain stitch S with the connecting yarn R, the advantages of the inserted tissue, that is, the cutting is reliable and easy, the advantages of the braided tissue, In other words, a connected structure having the advantages of two points that fuzz is not generated is adopted, thereby connecting the chain stitch S knitted with the covered yarn CY having the elastic yarn as the core yarn Y1, and By reliably cutting the spanning part B, it is possible to provide a warp knitted fluff yarn TY having a uniform length and uniform fluff yarn F, having elasticity, and at the same time, having no fluff loss.

[0022]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
In the present invention, the warp knitted fabric T is knitted using a tricot machine.
That is, as shown in FIG. 6, a large number of chain stitches S are knitted, and at the same time, these chain stitches S are connected by the connecting yarn R to obtain a warp knitted fabric T.
The connected structure RK of the connecting yarn R is indicated by a bold line.
While the warp knitted fabric T is wound in the direction of arrow A, the connecting yarn R is cut in the wale W direction by the cutter CT installed on the machine, and the chain knitting S is separated in the vertical direction.
[0023]
One cutter CT is installed between each of the chain stitches S and S in the vicinity of the winding portion of the tricot machine.
As for the cutting mechanism and the cutter shape, there are a method in which a large number of round blades are passed through a rotating shaft and rotated all at once, a method in which a cutter is reciprocated and cut, and any of them may be used.
As shown in FIG. 7, the separated chain knitting S becomes a fluff yarn F and protrudes from the surface in a state of being almost orthogonal to the chain knitting S. Knitted wool yarn TY.
[0024]
The connection structure RK of the connection yarn R will be described in detail with only one connection yarn R shown in FIG.
The chain stitch S is not described here in order to avoid complication of the figure, and only its position is shown.
The connecting yarn R connects the chain stitches S and S with a connected structure RK composed of a connecting portion K formed on the chain stitch S and a spanning portion B spanned between the chain stitches S and S.
The connecting yarn R is connected to the chain knitting S by a connecting portion K composed of an upper end insertion structure TL, an intermediate structure ML having at least one knitting structure KL, and a lower end insertion structure BL. B is spanned between the same position courses C and C of the chain stitches S and S adjacent to each other.
[0025]
Here, since the connecting yarn R is stretched between the adjacent chain stitches S, S in the same position course C, C with an insertion tissue (upper end insertion tissue TL, lower end insertion tissue BL), it is maintained in a substantially horizontal state. It hits in a state orthogonal to the cutter CT, and is cut without causing a slip phenomenon.
Regarding the spanning between the chain stitches S, S of the connecting yarn R, it is important to span between the same position courses C, C of the adjacent chain stitches S, S.
[0026]
On the other hand, as shown in FIG. 9, for the chain stitches S1 and S2 knitted with the structure “10-01” by the oscillating L2, the connecting yarn R is connected by the knitting L1 to the linking structure RK “55-22-00”. -10-00-33-55-54 ", the bridging part B is indeed chained from the upper end insertion tissue TL to the lower end insertion tissue BL, although it is spanned by the insertion tissue. The course C1 of the knitting S1 is slanted over the course C2 of the chain knitting S2 by one course upward, and the bridging portion B does not become horizontal, but the knitting shown in FIG. Similar to the connection in the tissue, the spanning portion B is slanted, a slip phenomenon occurs when the cutter CT is cut, and there is no effect of using the inserted tissue.
[0027]
As for the connection structure RK of the connection yarn R, in addition to one series of connection structures RK that can be knitted with one sheet as shown in FIG. 6, two sheets (L1, L2) of ribs as shown in FIG. A multi-line connected organization RK organized by
The difference in the connected organization RK in this figure is due to the course deviation in which the knitting is performed by shifting by two courses.
In this way, instead of adopting a completely different connected organization RK, two series and three series can be achieved by knitting one series of connected organizations RK with course deviation.
By making the connected tissue RK into a multi-series, the number of fluff can be increased or the fluff density can be changed, and a warp knitted fluff yarn TY rich in change can be obtained.
[0028]
Further, in addition to the case where one chain Y is reciprocally coupled between two adjacent chain stitches S, S, as shown in FIG. 11, three chain stitches S1, S2, S3 (structure) Of course, it is possible to reciprocately connect between them (not shown) or to reciprocately connect between the chain stitches S.
[0029]
As for the connecting portion K of the connecting yarn R, the intermediate structure ML of the structure in which two knitted structures KL are continuous as shown in FIG. 12, and the knitted structure KL from the upper and lower sides as shown in FIG. Naturally, an intermediate tissue ML of the sandwiched tissue is possible.
[0030]
The warp knitted wool yarn TY produced in this way has no problem in cutting, and when used as the warp knitted fluff yarn TY, the connecting portion R in which the fluff yarn F has at least one knitted structure KL. Since it is connected to the chain knitting S, fluff does not occur even if it is strongly pulled during use.
Therefore, a knitted fabric (warp knitted fabric, flat knitted fabric, circular knitted fabric, etc.) or a fabric knitted using such a warp knitted fluff is extremely useful.
[0031]
Hereinafter, embodiments of the present invention will be described in more detail with reference to the examples. A warp knitted fabric T shown in FIG. 14 is knitted by a 28 gauge tricot machine according to the organization chart shown in FIG. 10 and using three lumps L3, L2, and L1.
Specifically, the covered yarn CY is threaded through Osa L3 in a 1-in-3-out manner, whereby a plurality of chain stitches S (only the positions are shown in FIG. 14) are formed with the chain stitch structure “10-01”. Organize.
Here, the 1-in-3-out threading means that after one covered yarn CY is threaded through the guide G of the boss L3, the thread is not threaded through the next three guides.
In other words, one knitting needle of the tricot machine is used and three are not used.
[0032]
Further, the connecting yarns R2 and R1 are also threaded through the cords L2 and L1 in a 1-in-3-out manner, respectively, and the connected structures (Osa L2 “00-55-54-55-00-10”, Osa L1 “00- 10-00-55-54-55 "), the chain stitches S and S are connected.
In FIG. 14, in order to clearly show the difference between the connected structures RK, each of the connecting yarns R1 and R2 is indicated by a thick line.
Each connected organization RK knitted by OSA L2 and OSA L1 has the same pattern and is only shifted by two courses.
The warp knitted fabric T (FIG. 14) knitted in this way is cut and separated in the wale W direction by a cutter CT provided on the machine to obtain a warp knitted wool yarn TY.
[0033]
The covered yarn CY used in this example uses a polyurethane yarn (22 dtex) for the core yarn Y1, a 66 wooly nylon yarn (33 dtex) for the wound yarn, and a twist number of 600 T / M.
For the connecting yarn R, rayon, Bemberg, acrylic, silk, acetate, or the like is used.
As the connecting yarn R, both Losa and L1 may be used by mixing, for example, using rayon or acetate for only one type, as well as rayon for L2 and acrylic for L1.
Furthermore, the thicknesses of the connecting yarns R1 and R2 can be one type, or can be used by mixing yarns of various thicknesses.
[0034]
Although the details of the present invention have been described above, it goes without saying that the warp knitted wool yarn TY is not limited to these embodiments, and other modifications and combinations are possible without departing from the essence thereof. Yes.
For example, the structure of the chain knitting S may be any of an opening, a closing stitch, or a combination of these, and the number of stitches is not limited, and may be 4 or 5 depending on the type of warp knitting machine. Good to use a lot.
Also, the knitting yarn to be used can be developed in various ways according to the purpose.
Furthermore, it goes without saying that the thread passing through the knitting for knitting the chain stitch is not limited to 1 in 3 out, but various types such as 1 in 2 out and 1 in 4 out are possible.
[0035]
