Description

  The present invention relates to a tubular knitted fabric in which a part in a circumferential direction is made thicker than others and a knitting method thereof.

  Using a flat knitting machine, the knitted fabric of the front side and the rear side is suspended in a layered manner below the needle bed, and the knitting yarn is alternately fed to the front side, the rear side, the front side, ... By doing so, a tubular knitted fabric in which the front side portion and the rear side portion are connected at both ends of the knitting width can be knitted. Conventionally, a tubular knitted fabric in which a part of the tubular knitted fabric in the circumferential direction is thicker than the others is knitted by a flat knitting machine. The part of the tubular knitted fabric here is a part of the tubular knitted fabric straddling either the front side portion or the rear side portion, or straddling both the front side portion and the rear side portion.

  Traditionally, intarsia technology has been used to obtain this type of knitted fabric. In other words, a unique yarn feeder is assigned to each of the thickening portion and the other portions, and the knitting is performed. In this case, the knitting of each part is performed by folding back knitting, and the knitted fabric is integrated by connecting the boundary portions with tacks. Reference 1 relates to protective gloves. The knitted fabric of this part is knitted by knitting the thumb and index finger pouches and the vicinity of the crotch part with yarn having higher abrasion resistance than other parts. Discloses a method of producing protective gloves that are thicker than the above part and have cut-resistant wounds at low cost. It is described that an aramid fiber can be used as a yarn having a large cut resistance, and a cotton yarn or a polyester fiber can be used as a yarn for knitting other portions.

In addition, Document 2 has a total thickness from the fingertip of the glove to the center of the palm to obtain a working glove suitable for a work requiring a fine hand such as assembly of a precision machine, as compared with other parts that remain. The present invention relates to a work glove in which a thin protective part of a knitted hand is provided with a film-like protective part made of rubber or synthetic resin. The way to make the thick and small parts is to change the number of yarns used at the time of knitting, to make the thin part and the thick part continuously, or to make the part you want to reduce the thickness of, for example, warm water It is disclosed that a method of dissolving a yarn made of PVA by knitting with a yarn made of PVA that dissolves in the yarn and a yarn that doesn't dissolve in warm water and soaking the knitted gloves in warm water after knitting can be adopted.

  Although literature 1 and literature 2 do not clearly describe the use of the intarsia technique, it can be estimated that gloves are knitted on the assumption of the intarsia technique. However, according to such a knitting method, the boundary portions of the respective portions are connected by tuck knitting, so that the strength of the boundary portions is inevitably weakened, or it becomes a cause of stiffness and tension. In addition, the connection is conspicuous, and the appearance of the knitted fabric is impaired.

  An object of the present invention is to provide a tubular knitted fabric in which a part of the circumferential direction of the tubular knitted fabric is thicker than the other without being connected by an intarsia technique, and a knitting method for obtaining the same.

  Another object of the present invention is to obtain a commercial knitted fabric by applying the tubular knitted fabric having such a structure to knitting knitwear such as sweaters, gloves and socks.

In the present invention, at least the first yarn feeder for supplying the first knitting yarn and the second yarn feeder for supplying the second knitting yarn are used to connect the front side portion and the rear side portion at both ends of the knitting width. A method for knitting a tubular knitted fabric with a flat knitting machine for making a part of the circumferential direction of the tubular knitted fabric thicker than others, comprising the following steps;
a) plating the thickening portion of the tubular knitted fabric from one end of the thickening portion to the other end using both the first yarn feeder and the second yarn feeder;
b) knitting the other part adjacent to the part to be thickened using the second yarn feeder from one end to the other end;
c) tuck knitting the thickened portion from the other end to the one end using the first yarn feeder;
d) A step of repeating the steps a) to c).

  Preferably, the plating knitting in step a) is performed using the first knitting yarn as the upper yarn.

  Preferably, in step c), the knitting needles that are tucked each time are changed so that the tack appears in a 1 × 1 canopy shape.

  The first knitting yarn and the second knitting yarn are the same type of knitting yarn.

  The first knitting yarn and the second knitting yarn are different knitting yarns.

  Preferably, the first knitting yarn is thicker than the second knitting yarn.

  A tubular knitted fabric is knitted as knitwear such as sweaters, gloves and socks.

  Preferably, the tubular knitted fabric is a glove, and either one of the palm side and the back side of five fingers, four torso and five torso is knitted thicker than the other.

  Preferably, the tubular knitted fabric is a glove, and the thumb and index finger pouches and the vicinity of the crotch are knitted with a large knitting yarn with cut resistance.

  Further, in the tubular knitted fabric of the present invention, either a front side portion or a rear side portion is connected to a tubular knitted fabric in which a front side portion and a rear side portion are connected at both ends of a knitting width using a flat knitting machine, or Part of the tubular knitted fabric straddling both the front side portion and the rear side portion is a first knitted fabric portion of the tubular knitted fabric, and the second knitted fabric has the first knitted fabric portion as another portion of the tubular knitted fabric. A tubular knitted fabric knitted as being thicker than the ground portion, wherein the first knitted fabric portion of the tubular knitted fabric is both the first knitted yarn and the second knitted yarn, and one of the first knitted fabric portions. The second knitted fabric portion following the first knitted fabric portion is knitted with the second knitting yarn from one end of the second knitted fabric portion toward the other end. While being knitted, the first knitting yarn is tuck-knitted from the other end of the first knitted fabric portion toward one end.

  Preferably, the knitting of the first knitted fabric portion by both the first knitting yarn and the second knitting yarn is plated with the first yarn as the upper yarn and the second yarn as the lower yarn.

  The tubular knitted fabric is knitwear such as sweaters, gloves and socks.

  Preferably, the tubular knitted fabric is a glove, and either one of the palm side and the back side of five fingers, four torso and five torso is thicker than the other.

  More preferably, it is a coated glove having a thick upper side and a coating on the palm side.

  Preferably, the tubular knitted fabric is a glove, and the thumb and forefinger finger bags and the vicinity of these crotch portions are knitted with a large knitting yarn having cut resistance.

  According to the present invention, the thickened portion in the circumferential direction of the tubular knitted fabric is plated with both the first knitting yarn and the second knitting yarn, and the first knitting yarn is not used for the knitting of other portions. Since only the second knitting yarn is used, a knitted fabric having a partially different thickness can be obtained. Further, since the thickened portion is tack knitted with the first knitting yarn, the thickness can be further increased accordingly. Furthermore, since the circular course of the tubular knitted fabric is continuously formed by the second knitting yarn, the boundary between the thickened portion and the other portion may be tucked together as in the case of intarsia. And intarsia-specific problems do not occur.

  Since the first knitting yarn is plated with the upper knitting yarn and the second knitting yarn as the lower yarn, the first knitting yarn can be represented on the outer side (front side) of the tubular knitted fabric.

  Further, even if the first knitting yarn and the second knitting yarn are the same type of knitting yarn, the portion where the loop is formed by both the first knitting yarn and the second knitting yarn can be formed thick. It is not necessary to prepare different kinds of yarns having different thicknesses in advance.

  By using different knitting yarns for the first knitting yarn and the second knitting yarn, and appropriately using the knitting yarn of the material, a tubular knitted fabric corresponding to the application and performance can be obtained.

  Further, if the first knitting yarn is thicker than the second knitting yarn, the thickness of the thickened portion can be further increased.

<Example 1>
As a preferred embodiment of the present invention, an embodiment in which a part of the circumferential direction of a cylindrical knitted fabric composed of a front side part and a rear side part is knitted thicker than other parts will be described below with reference to the drawings. FIG. 1 shows a tubular knitted fabric 1 of the present embodiment. The boundary between the front side portion 3 and the rear side portion 5 of the tubular knitted fabric 1 coincides with the boundary of the knitted fabric that is different, and the left boundary is indicated by EL and the right boundary is indicated by ER. In this embodiment, the rear side portion 5 is knitted thicker than the front side portion 3. FIG. 2 shows the knitting steps of the tubular knitted fabric.

  For the knitting of the tubular knitted fabric 1, two yarn yarn feeding first yarn feeders (hereinafter referred to as Y1) and second yarn feeders (hereinafter referred to as Y2) are used. The knitting yarns assigned to Y1 and Y2 are of the same type, but they may be of different types. As the different types, any material may be used as long as the texture of the yarn is different, such as the difference in thread thickness, color, and material. The left and right arrows in the figure indicate the knitting direction. FB represents the front needle bed, BB represents the rear needle bed, A to J represent the knitting needles of the front needle bed, and a to j represent the knitting needles of the rear needle bed. The front side portion 3 constituting the tubular knitted fabric 1 is knitted with a knitting needle on the front needle bed, and the rear side portion 5 is knitted with a knitting needle on the rear needle bed. For convenience of explanation, the number of stitches used for knitting is less than the actual number of stitches. As the flat knitting machine used in each embodiment, a full jacquard needle selection and a flat knitting machine having a function capable of switching color yarns at an arbitrary position can be used. Y1 and Y2 are set on the left side of the tubular knitted fabric at the start of knitting, but FIG. 2 shows the positions of Y1 and Y2 when the step is completed.

  Details of the organization will be described below. First, in step 1, the knitting needles a to j on the rear needle bed are fed to perform the course knitting of the rear side portion 5 of the tubular knitted fabric 1. Here, the same course knit loop is formed by the respective knitting yarns by plating knitting in which Y1 and Y2 are simultaneously assigned to the same knitting cam (not shown) of the carriage. The Y1 knitting yarn is plated as the upper yarn (front yarn), and the Y2 knitting yarn is plated as the lower yarn (back yarn).

  In the subsequent step 2, the knitting loop of the front side portion 3 of the tubular knitted fabric 1 is formed by supplying yarns to the knitting needles J to A of the front needle bed using Y1. Step 3 feeds yarns to every other knitting needles i, g, e, c on the rear needle bed at Y2 to form a tack loop. Note that the knitting of step 2 and step 3 may be performed after step 3 is performed. In the case of a flat knitting machine having a plurality of knitting cams in the carriage, steps 2 and 3 can be performed by one traverse of the carriage, but in the case of a flat knitting machine having only one knitting cam. Then, a course knitting for one round of the tubular knitted fabric is performed by inserting a right-facing empty course between each step.

  Next, Steps 4 to 6 show course knitting for one round following the tubular knitted fabric 1. Here, the knitting needles used for the tuck knitting in step 6 are the same as those in steps 1 to 3 except that they are different from those in step 3. Therefore, only the different parts will be described below. In step 6, a tuck loop is formed by feeding yarns to every other knitting needles h, f, d, and b on the rear needle bed that were not used for knitting in step 3.

  The course for two rounds of the front side part 3 and the rear side part 5 which comprise the cylindrical knitted fabric 1 by the said knitting is formed. The tubular knitted fabric 1 shown in FIG. 1 can be obtained by repeating these knittings a desired number of times. The rear side portion 5 of the tubular knitted fabric 1 is thicker than the front side portion 3 by the amount of knitting yarn. Further, since a tack loop is formed, the thickness is increased accordingly. Since the tuck loop is formed in the shape of a canopy, the rear side portion 5 can be formed with a uniform thickness as a whole. Of course, the tack knitting is not limited to a canopy shape, and may be changed as appropriate.

<Example 2>
Next, a tubular knitted fabric according to the second embodiment will be described. The tubular knitted fabric according to this example is applied to the gloves 11 as knitwear. Since the method of seamlessly knitting gloves using a flat knitting machine is well known, its details are omitted here.

  FIG. 3 shows a glove 11 according to this embodiment. The palm side of the glove including the finger bags 13 to 17 is knitted thinly with respect to the back side of the glove including the finger bags 13 to 17. In the case of gloves, the knitting of the above-described embodiment may be applied to the knitting of five finger bags, the cylindrical knitting forming the four barrels 18, and the five coppers 19. Although not shown, the same applies to the case where three cylinders are provided. In the case of mittens gloves, the four fingers 13 to 16 from the little finger to the index finger may be considered as one tubular knitted fabric.

  For example, if the knitting yarn is prepared so that the back side has a normal thickness when the glove is completed, the palm side can be formed so thin. Since only the palm side can be thinned, a more preferable one than the original hand of the coated glove described in Reference 2 can be obtained. In this case, it is preferable to use a knitting machine having a gauge of 15 gauge or more. For example, a single yarn of No. 30 twin yarn (30/2) is assigned to Y1 and Y2 and knitted. Since the palm side of the glove including each finger bag is knitted thinly, it is easy to perform fine work, and the upper side can be made to function as a cold protection because it is thick. In addition, if the coating is applied only to the thin part and the thickness of the coating film added at that time is the same as the thickness on the back side of the glove, the glove should have a uniform thickness as a whole. You can also.

  Of course, processing other than coating may be performed or the product may be left unprocessed. In any case, the knitting yarn used for knitting is arbitrary regardless of whether it is the same or different, and the knitting yarn may be appropriately determined according to the use. Of course, contrary to the above, if all or part of the palm side of the glove is made thicker than usual, a function such as shock absorption can be added to the glove.

<Example 3>
Next, the tubular knitted fabric according to the third embodiment will be described. In this example, it is applied to protective gloves. FIG. 4 shows the protective glove 21 of the present embodiment. In the above-described embodiments, the front side portion 3 and the rear side portion 5 of the tubular knitted fabric 1 have different thicknesses. However, in this embodiment, the cylinder straddling both the front side portion 3 and the rear side portion 5. It is a glove in which a part of the knitted fabric is formed thick. Specifically, the finger bag of the thumb 24 and the index finger 23 and the vicinity of the crotch portion are formed thickly using a knitting yarn having a large cut resistance to form the reinforcing portion 22. In particular, the portion following the four torso 25 of the index finger and the portion following the five torso 26 of the thumb are portions straddling both the front side portion 3 and the rear side portion 5 of the tubular knitted fabric. FIG. 5 shows the structure of the cylindrical body of the line XX of the five cylinders of the glove 21 of FIG. 5 indicates a boundary line between the front side portion 3 and the rear side portion 5, and a front side boundary between the reinforcing portion 22 and the ground knitting portion 27 is indicated by EF, and a rear side boundary is indicated by EB.

  FIG. 6 shows the knitting steps in the five cylinders 26 of FIG. 5, which is a modification of the knitting steps of FIG. 2, and the basic idea is the same. The same applies to the knitting with the four cylinders 25. A flat knitting machine having two or more knitting cams was used as the flat knitting machine used for knitting, and the knitting was performed so as to increase productivity by eliminating an empty course. As the knitting yarn forming the reinforcing portion 22, an aramid fiber having a high wear resistance is used. As an example, a commercially available thread such as Kepler or Spectra is used. These aramid knitting yarns are used for Y1, and are knitted as upper yarns during plating knitting.

  Details of the organization will be described below. First, in Step 1 and Step 2, the knitting of the reinforcing portion 22 is performed by performing plating knitting with Y1 and Y2. Step 1 feeds the knitting needles J to A of the front needle bed to form a knit loop of the reinforcing portion 22 in the front side portion 3. In step 2, the knitting needles a to j of the rear needle bed are fed to perform the course knitting of the reinforcing portion 22 in the rear side portion 5 in the same manner.

  In Step 3, Y1 is used to feed the needles i, g, e, c, and a of the rear needle bed to the left to form a tuck loop every other in the reinforcing portion 22 in the rear side portion 5, and Y2 is Move to a position beyond the knitting needle k for subsequent knitting. In step 4, Y2 feeds the knitting needles k to r on the rear needle bed to perform course knitting of the ground knitting portion 27 of the five cylinders, and Y1 feeds the knitting needles B, D, F, and H on the front needle bed. Then, every other tuck loop is formed in the reinforcing portion 22 in the front side portion 3. In the next step 5, Y2 feeds the knitting needles RK of the front needle bed to perform the course knitting of the ground knitting portion 27 of the front side portion 3 following the rear side portion 5 and before that, Y1 becomes an obstacle to knitting by Y2. It moves to the left of the knitting needle K so that it may not become. By these knitting, a course of one round of the five cylinders 26 is formed. Step 6 shows a state where Y1 and Y2 are moved to the right side of the knitting needle J in order to perform the course knitting of the subsequent second course.

  Although not shown in FIG. 6, the knitting needle for performing the tuck knitting of the reinforcing portion 22 in the second course is the knitting needle in which the tuck loop is formed in steps 3 and 4 in order to form a tack loop in a canopy shape as in FIG. Use alternate knitting needles that are different from. When the steps 1 to 6 are repeatedly performed, the reinforcing portions 22 in the five cylinders 26 are formed while changing the needles used for tack knitting each time as described above.

  In the above embodiment, an example of a glove is shown as a tubular knitted fabric, but it goes without saying that it can be applied to socks, sweaters and the like. Moreover, it can be set as knitwear which has the effect completely different from a coating and a protective glove by selecting suitably the knitting yarn allocated to Y1, Y2 according to a use.

[0006]
A knit loop of the same course is formed with each knitting yarn by plating knitting assigned to the same knitting cam (not shown) of the wedge. The Y1 knitting yarn is plated as the upper yarn (front yarn), and the Y2 knitting yarn is plated as the lower yarn (back yarn).
[0036]
In the subsequent step 2, the knitting loop of the front side portion 3 of the tubular knitted fabric 1 is formed by supplying yarns to the knitting needles J to A of the front needle bed using Y2. In step 3, Y1 feeds yarns to every other knitting needle i, g, e, c on the rear needle bed to form a tack loop. Note that the knitting of step 2 and step 3 may be performed after step 3 is performed. In the case of a flat knitting machine having a plurality of knitting cams in the carriage, steps 2 and 3 can be performed by one traverse of the carriage, but in the case of a flat knitting machine having only one knitting cam. Then, a course knitting for one round of the tubular knitted fabric is performed by inserting a right-facing empty course between each step.
[0037]
Next, Steps 4 to 6 show course knitting for one round following the tubular knitted fabric 1. Here, the knitting needles used for the tuck knitting in step 6 are the same as those in steps 1 to 3 except that they are different from those in step 3. Therefore, only the different parts will be described below. In step 6, a tuck loop is formed by feeding yarns to every other knitting needles h, f, d, and b on the rear needle bed that were not used for knitting in step 3.
[0038]
The course for two rounds of the front side part 3 and the rear side part 5 which comprise the cylindrical knitted fabric 1 by the said knitting is formed. The tubular knitted fabric 1 shown in FIG. 1 can be obtained by repeating these knittings a desired number of times. The rear side portion 5 of the tubular knitted fabric 1 is thicker than the front side portion 3 by the amount of knitting yarn. Further, since a tack loop is formed, the thickness is increased accordingly. Since the tuck loop is formed in the shape of a canopy, the rear side portion 5 can be formed with a uniform thickness as a whole. Of course, the tack knitting is not limited to a canopy shape, and may be changed as appropriate.
[0039]
<Example 2>
Next, a tubular knitted fabric according to the second embodiment will be described. The tubular knitted fabric according to this example is applied to the gloves 11 as knitwear. Since the method of seamlessly knitting gloves using a flat knitting machine is well known, its details are omitted here.
[0040]
FIG. 3 shows a glove 11 according to this embodiment. The palm side of the glove including the finger bags 13 to 17 is knitted thinly with respect to the back side of the glove including the finger bags 13 to 17. In the case of gloves, the knitting of each finger bag of five fingers is the same as that of the above embodiment for the tubular knitting that forms the four barrels 18 and the five copper 19
