TECHNICAL FIELD OF THE INVENTION
The present invention relates to improvement of a knitted fabric at the time of producing a sheet pile fabric using a circular knitting machine or the like.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a technique described in, for example, Japanese Patent Publication No. 60-1420 has been known for producing a raised fabric such as artificial fur. This technique has a main feature of extending a seal yarn on both sides of a ground tissue and raising the seal yarn. Basically, a technique of implanting piles in the ground tissue is disclosed.
[0003]
By the way, when a pile yarn is conventionally extended by using a sheet of knitted fabric for a knitted fabric, the pile yarn is appropriately knitted into the knitted fabric by a circular knitting machine or inserted and knitted. There is a pile knitting with such a point needle. In addition, as a pile knitting with a cutting knife, attach a knife provided at the point of the point, cut the pile with a knife when the post-policy floor finishes knitting and sink, and further separate knitting with both kettles of a circular knitting machine There is a method of manufacturing piles, using pile yarns to connect the ground structures of both knitted fabrics, cutting the pile yarns with a cutting knife provided between both knitted fabrics, and obtaining two pile knitted fabrics. .
[0004]
In the conventional example described above, for example, in pile knitting using a cut knife, a cylinder needle projects from the knitted fabric, knits the pile yarn at one glance of the knitted fabric, and cuts the pile yarn with a cut knife provided on the needle. The pile yarn is knitted on the knitted fabric. FIG. 4 shows an example of this conventional technique. When knitting is performed in this manner, the pile yarn is knitted in a pine needle shape at a glance of the knitted fabric. is there. In particular, when raising the pile yarn, the pile yarn is scratched in a direction in which the pile yarn comes off, so that the pile may come off at the raising stage. In order to prevent this, it is common to apply a resin to the back of the knitted fabric (knitted fabric) and process it so that the pile does not come off. However, the knitted fabric is hardened by the application of the resin, and the drape property is inferior. There is a problem.
[0005]
In the case of circular knitting machines, cylinder needles are lined up around the cylinder of the shuttle, and the pile is hooked on the knitted fabric while moving the cylinder needle up and down at a high speed. The length of the pile is limited by the speed at which the cylinder needle moves up and down. Will be done. That is, if the knitting speed is to be increased in order to improve mass productivity, the speed at which the cylinder needle moves up and down, in other words, the reciprocating distance is limited, so the pile length is at most about 20 mm with respect to the knitted fabric. Can only be done. On the other hand, if the pile length is to be increased, the knitting speed must be reduced, which causes a problem that mass productivity is poor. In addition, if the pile length is as short as the current situation, even if it is raised, the raising density must be increased, so the pile material becomes heavier as a whole and it is not possible to manufacture a knitted fabric with a light texture . Therefore, it was difficult to obtain artificial fur with long hair feet by mass production using conventional techniques.
[0006]
An object of the present invention is to solve the above-mentioned conventional problems, and to provide a product in which the pile is longer than before and the pile is hardly removed from the knitted fabric.
[0007]
[Means for Solving the Problems]
In the present invention, in order to achieve the above object, a pile knitted fabric knitted by a circular knitting machine, wherein a plurality of wales arranged in a knitting direction in a knitted fabric are grouped, and one end of a pile yarn knitted in the knitted fabric is A pile knit extending from one outermost side of the group of wales, the other end extending from the other outermost side of the group of wales, and the one end and the other end are connected by an intermediate portion of the pile yarn. Obtained. In this knitted fabric, when the cylinder needle is moved in the vertical direction, there is more room than before in the operation of the next cylinder needle, so that the stroke of the vertical movement can be set larger. Therefore, the pile length can be made considerably longer than before. In addition, the middle part of the pile yarn whose both ends are extended from the knitted fabric is supported by the knitted fabric with a group of wale skipped, and one pile yarn is knitted at two places, as in the conventional case. Compared with the pile yarn knitted at a glance, the pile is less likely to fall off, and the amount of resin applied to the back side of the knitted fabric can be reduced.
[0008]
Furthermore, by means of raising the pile yarn after weaving, artificial fur having a long hair foot and excellent texture even when the density of pile yarn implantation is reduced is completed. Further, by configuring a group of wales with at least four wales, the density can be significantly reduced as compared with the conventional case.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a knitting structure diagram showing an example of a pile knitted fabric of the present invention, wherein 1 is a plain knitted fabric knitted by a circular knitting machine, and courses 2a, 2b to 2n are aligned in a vertical direction by weft knitting. ing. Numeral 3 is a unit in which five wales are grouped in a horizontal direction as viewed from each course. Reference numeral 4 denotes a pile yarn provided for a group of wale 3a to 3e. The pile yarn is knitted into the first wale 3a, and one end 4a is knitted on the outside thereof, and is knitted on the final wale 3e. The other end 4b extends. The intermediate portion 4c of the pile yarn 4 is designed such that when knitting the intermediate wale 3b to 3d, the cylinder needle once enters the base knitting structure as in the case of the wale 3a and 3e, but returns without catching the pile. ing. Therefore, this portion is in a free state without being entangled in the ground stitch. By knitting the pile yarn into the ground knit as described above, one pile yarn 4 is knitted at two places and the resistance is increased, so that even if a pull occurs, it does not easily fall off. In the present embodiment, the number of the wale in one group is set to five, but the present invention is not limited to this, and a smaller or larger number may be set to one unit. However, if two or three pieces are defined as one unit, the flocking density becomes high, so that four or more wales are preferably defined as one unit.
[0010]
In order to knit the pile knitted fabric of the present embodiment, pile yarns 12 are set on a large number of dial needles 11 while knitting a ground knit with a circular knitting machine as shown in FIG. By moving up and down the cylinder needle 13 provided around the cylinder, the pile yarn 12 cross-linked to the dial needle 11 is hooked and lowered, and at the same time, a roller (not shown) is attached to a cut knife 13a provided in advance to the cylinder needle 13. The pile yarn is cut by pressing. In FIG. 2, a large number of cylinder needles 13 are provided in parallel. Among them, A, C, and E perform an operation of hooking a pile yarn, and B and D rise once in the direction of the dial needle. Without returning to the bottom. The cylinder needles a to d are not operated by setting the cam in advance. By this operation, in the embodiment of FIG. 2, three piles are skipped, the pile yarn is hooked and cut. In this way, the hand can return to the return direction with sufficient time after moving in the direction of the dial hand 11 instead of repeatedly reciprocating, so that the stroke can be set longer. As a result, the pile can be lengthened. In addition, since the operation of the needle becomes slower than in the related art, accidents such as broken needles can be limited.
[0011]
FIG. 3 is an enlarged view of the organization of the wales 2 at both ends where the pile yarns 12 of the group of wale are woven.
[0012]
According to the present embodiment, for example, when the group of the wale is five, and when the cylinder needle is operated by the cam, it is possible to extend the pile yarn of about 40 mm, which is considerably longer than in the past. Therefore, the pile knitted fabric of the present invention is a pile knitted fabric with long hairy feet.
[0013]
The pile knitted fabric obtained as described above is then raised with a known raising machine or raising means. Since the pile yarns are knitted with respect to the wales at both ends of the knitted fabric and are connected to each other by the intermediate portion, even if the piles are scratched during raising, the pile yarns are less likely to fall off. Further, since the pile yarn length is long in spite of the low planting density of the pile yarn, the artificial fur is light and has a good texture after raising. In the present embodiment, the pile yarn is described on the assumption that a yarn that can be raised by a raising machine is used, but not only the raised yarn but also a monofilament or a non-raised yarn is mixed at appropriate intervals. It is needless to say that the range is freely selectable and can be selected depending on the use of the pile knitted fabric.
[0014]
【The invention's effect】
In the present invention, the composition of the pile knitted fabric is a group of a plurality of wales arranged in the knitting direction in the knitted fabric as described above, and one end of the pile yarn woven into the knitted fabric extends from one outermost side of the group of wales. At the same time, the other end extends from the other outermost side of the group of wales, and the one end and the other end are connected by an intermediate portion of the pile yarn, so that the pile yarn can hardly come off. In addition, in the case of manufacturing the product of the present invention using a circular knitting machine, the operation of the cylinder needle is smaller than in the conventional case, and the cylinder needle is not knitted in the middle wale, so that there is sufficient time margin. As a result, the cylinder needle can be moved with a long stroke. Therefore, a long pile can be knitted, and a pile knitted fabric having a long hairy foot can be provided.
[0015]
Furthermore, by adopting a configuration in which the pile yarn does not easily come off, it is possible to omit the backing of the resin on the back surface, which has been required in the past, or to reduce the amount of resin applied, so that a knitted fabric with a rich drape property or artificial fur can be used. It is possible to do.
