Description

The present invention, various underwear, in particular a circular knitting fabric suitable for use in inner products such as ladies' underwear, inner product consisting of the circular knitting fabric, and those related to organizing how the circular knit fabric is there.

  Conventionally, circular knitted fabrics used for various inner products such as women's underwear, such as shirts with sleeves and camisole, and five-minute spats and other various inner products, A piece knitting method is incorporated into the machine, and the body knitting part such as the body and sleeves of the product and the mouth knitting part such as the cuffs and cuffs are automatically knitted on the same knitting machine by changing the organization automatically. Often, knitting is performed by using a so-called molded circular knitting machine (circular knitting garment machine) in which a product is provided with a yarn removal course for each product, and after knitting, the product is separated into each product by the yarn. ).

  When the circular knitted fabric for this molded inner product is molded and knitted with a double cylinder type circular garment machine, if the body part such as the body and sleeves is made into a single knitting structure, There is a great difference in the knitting length of the yarn between the knitting structure of the hem and cuffs such as the rib knitting and the double knitting structure. For this reason, the yarn feeding method based on the negative feed is inevitably adopted as the yarn feeding method for knitting.

  Furthermore, even in the knitting structure of the knitted portion such as the hem and the cuff, in order to show an aesthetic edge, for example, two types of thread knitting lengths such as a rib knitting structure and a bag knitting structure are different. It is often composed of a knitting structure. Therefore, it is necessary to adopt a negative feed method in the knitting of the mouth knitting part. The yarn feeding method had to be adopted.

  Therefore, the fabric standard of the knitting part is actually forced to select a fabric in a range that does not cause a problem in quality even with the yarn feeding method by negative feed, and many are described in Patent Document 1 as well. As you can see, it is a double-knitted structure with double-ended needles. For example, in the case of knitting a reversible circular knitted fabric having different functions on the front and back sides, there is no choice but to adopt a double knitting structure. As a result, it has to be thick.

  By the way, in recent years, consumer preferences of women's underwear such as fashionable innerwear for women, and molded inner products such as general underwear are shifting to thin land without thickening, especially women. In an inner product for use, a thin knitted fabric by single knitting is often required. In addition, this circular knitted fabric for inner products is required to have a reversible function that can use the front and back functions in addition to the stretch function that gives a moderate tightening feeling to the background, although it varies depending on the application. It is also demanded that the fabric is made of a molded knitting (garment knitting).

Conventional thin inner products are often knitted with circular knitting (sink knitting), warp knitting cuts, or circular knitted barrel-shaped sewing products, or similar molding knitting machines, such as hems and cuffs. For the knitting part, it is common to sew materials with different functions or to fold back, so that the outer knitting line of the inner product appears through the outer garment, etc. There is a need to eliminate this effect.

It is possible to provide a circular inner knitted fabric and a molded inner product such as a ladies' underwear using the fabric.

In addition, according to the knitting method of the circular knitted fabric of the present invention, in the forming knitting by the double cylinder type circular knitting garment machine, the body knitting part is a structure such as a single knitted bear tengu knitting, each hem and cuffs, etc. The knitted portion can be knitted integrally with a structure such as a double knitted rib without any problem, and the circular knitted fabric can be knitted and produced efficiently. In particular, the mouth knitted portion is reluctant feed, only knitted part by knitting by feeding yarn positively feeding the knitting of circular knit fabric becomes possible without problems, further, in each of the yarn feed unit, three A circular knitting with a reversible function that can be knitted to form a three-layer structure with a bare tentacle knitting structure using the three types of yarns by using a yarn path component that can feed yarns while maintaining a constant yarn arrangement The fabric can be knitted.

  Next, embodiments of the present invention will be described based on examples shown in the drawings.

  FIG. 1A is a schematic plan view of a continuous knitted fabric in a state in which a circular knitted fabric A as a single product is continuously knitted by a double cylinder (upper and lower hook) type circular knitting garment machine. b) is a schematic plan view of a circular knitted fabric A as a single product separated by a drawn yarn after the knitting, for example, after finishing such as dyeing. FIG. 2 is a schematic enlarged view of a part of the stitches of the bear tengu knitting structure. FIG. 3 is an enlarged view of one loop of the above. FIG. 4 is a structure diagram showing the rib knitting structure (a) and the bag knitting structure (b).

  The single-piece circular knitted fabric A of the present invention is molded and knitted by a circular yarn garment machine of a thread separation type, particularly a double cylinder type circular knitting garment machine having two sets of upper and lower needles, which is also called a lynx / lynx machine. The body knitting part 1 such as the body and sleeves of the product is a single knitting structure with the needle of the lower cylinder (bottom hook), in particular, the bare knitting structure shown in FIG. Mouth knitted portions 2 such as cuffs, shoulders and feet are knitted integrally with a double knitted structure with double-ended needles of upper and lower cylinders (upper and lower hooks), for example, a rib knitted structure (rubber knitted structure) in FIG. Become. Usually, a single circular knitted fabric A composed of the body knitting portion 1 and the knitting knitted portion 2 has several dozen or more sheets through a take-off yarn course 3 for separation as shown in FIG. A large number of sheets (for example, 50 to 100 sheets) are continuously knitted, and after being subjected to finishing processing such as dyeing and washing in this continuous state, the single circle of FIG. Separated into knitted fabric A.

  As shown in FIG. 3, the body knitting part 1 of the circular knitted fabric A includes a front yarn Y1 and a back yarn Y3 made of substantially non-stretchable fibers, and elastic yarn such as a bare yarn having a stretch property, ie, a polyurethane yarn. A reversible knitted fabric that is knitted with the above-mentioned bare yarn knitting structure so as to form a three-layer structure with three types of yarns including the middle yarn Y2 and that differs depending on the material of the front yarn Y1 and the back yarn Y3 that appear on the front and back sides. It is organized to exhibit the effect as. In particular, the front yarn Y1 and the back yarn Y3 are knitted using yarns of different materials. In addition, when a bare tentacle knitting structure is knitted with two kinds of yarns including elastic yarns such as polyurethane yarns, for example, the surface yarns and elastic yarns, the fabric may be twisted. By weaving the back yarn Y3 that acts as a reverse torque at the same time, the twist of the fabric can be suppressed, the plating property can be improved, and the breaking strength can also be improved.

  The knitting part 2 is based on the three types of yarns Y1, Y2 and Y3, and has an elasticity obtained by winding a thin nylon yarn with a polyurethane elastic yarn as a core yarn once every other course or by winding it twice or double. For example, the rib knitting structure is knitted by four types of yarns to which a covered yarn (not shown) is further added, so that the expansion and contraction function is enhanced and the knitted fabric structure is stabilized. In the neck knitting portion 2, in order to improve the finish of the edge after separation, several courses on the knitting start side, for example, two courses are knitted with the bag knitting structure shown in FIG. It shall be knitted with a rib knitting structure of double knitting.

  The knitting method of the circular knitted fabric A will be described together with a part of the improved configuration of the knitting machine (double cylinder type circular knitting garment machine) to be used.

  First, for the yarn used, among the three types of yarn used for knitting of the body knitting portion 1, as the front yarn Y1 and the back yarn Y3, a long fiber type yarn such as polyester, nylon, rayon, or acrylic, Choose from polyester, rayon, cotton, hemp, wool and other short fiber type yarns, various other synthetic fiber yarns and natural fiber yarns, or blended yarns of these, depending on the product to be knitted. Can be used. Also, the thickness of the yarn varies depending on the use of the product made of circular knitted fabric, but it is 22 to 550 dtex yarn for the long fiber type, and 100/1 to 10/10 on the cotton count display for the single fiber type. As an elastic yarn such as No. 1 yarn or polyurethane yarn, a yarn of 11 to 220 dtex is used, and as the covered yarn as the fourth yarn, a yarn of 55 to 550 dtex is preferably used. However, depending on the product, a yarn outside the above range may be used.

  For example, a 60/1 (cotton count) rayon spun yarn (Z-twist) called Modal Microsoft (manufactured by Shikibo Co., Ltd.) is used as the front yarn Y1, and a 33 dtex wooly is used as the back yarn Y3. A nylon-processed yarn (Z-twisted) is used, and a 22 dtex polyurethane elastic yarn (so-called bear yarn) is used as the middle yarn Y2. Further, as the covered yarn which is the fourth yarn used for knitting the knitted knitted portion 2, a covered yarn having a total fineness of 77 dtex in which 22 dtex polyurethane elastic yarn is used as a core yarn and 55 dtex nylon fiber yarn is wound once is used. .

  When the circular knitted fabric A of the present invention is knitted by a double cylinder type circular knitting garment machine, the knitting is usually started from the side of the knitted portion 2 such as the hem and the cuff, and knitted in the direction of the arrow in FIG. When the knitting part 2 is finished knitting, the knitting is carried out by knitting the body part 1 such as the body and sleeves. Further, when the knitting part 1 is finished, one or several courses 3 for the drawn yarn are formed. Thus, the knitting from the knitting part 2 to the body knitting part 1 is repeated, and the circular knitted fabric A as a single product is knitted continuously as shown in FIG.

  Specifically, in the knitting of the knitted knitted portion 2, a double-knitted knitting structure, for example, several courses from the beginning of knitting, is basically performed using the double-ended needles of the upper and lower cylinders (upper and lower hooks) of the circular knitting garment machine. Preferably, two courses are knitted with the bag knitting structure of FIG. 4B, and thereafter knitted with the rib knitting structure of FIG. 4A. Since the yarn length of the rib knitting structure is longer than the yarn length of the bag knitting structure, and there is a difference of about three times between the yarn lengths of the two structures, the yarn feeding method inevitably needs to be fed with a negative feed. . In other words, the knitting part 2 knitted by feeding each yarn with a negative feed.

  In the knitting of the knitting knitted portion 2, the material is basically made different by the yarn path constituting member described later disposed in each yarn feeding port of even numbered ports such as 4 ports and 6 ports provided in the knitting machine. The front yarn Y1, the back yarn Y3, and the middle yarn Y2 are fed in a predetermined arrangement, and at any one of the odd-numbered and even-numbered yarn feeders, the knitting of the knitting portion 2 is performed. In this case, the covered yarn as the fourth yarn is knitted in addition to the three types of yarns, and the covered yarn is knitted every other course of the rib knitting structure. To do.

When the knitting part 2 of the predetermined length (predetermined course) is finished, the transition is made from the rib knitting structure by the double knitting using the upper and lower cylinders to the knitting of the bare knitting structure by the single knitting using only the lower cylinder. The body knitting portion 1 is knitted continuously and integrally.

  In particular, when knitting the body knitting portion 1, three kinds of yarns, that is, the front yarn Y1, the middle yarn Y2 of the bear yarn, and the back yarn Y3 are supplied from the respective yarn feeders provided in the knitting machine, as will be described later. Thus, the yarn is fed to the knitting needle portion of the lower cylinder so as to maintain a fixed position, and the above-mentioned bare tentacle knitting structure is knitted to form a three-layer structure.

  In addition, each of the three types of yarns, the front yarn Y1, the middle yarn Y2, and the back yarn Y3, has different knitting tensions due to the difference in material, so the yarn feeding method is to actively feed each yarn individually. It is indispensable condition for knitting to feed yarns with Therefore, in the knitting of the body knitting portion 1, for example, yarn is fed by positive feeding using a yarn feeding device described later and knitted. In this way, by knitting each yarn of different materials with positive feed, the three types of yarns Y1, Y2, and Y3 can be knitted without any problem so as to form a three-layer structure while maintaining the arrangement. Become.

  When the body knitting portion 1 has finished knitting, the process proceeds to the knitting of the course for yarn removal, and after knitting several courses for the yarn removal, the knitting of the mouth knitting portion 2 and the body knitting portion 1 as described above is performed. The circular knitted fabric A that is a product obtained by integrally knitting the body knitting portion 1 and the mouth knitting portion 2 is successively knitted in a continuous manner through a yarn removal course 3 for separation. The continuous knitted fabric is subjected to finishing processing such as dyeing and washing, and then separated into a single circular knitted fabric A shown in FIG.

  In the knitting described above, when the body knitting portion 1 is knitted, each yarn is positively fed due to the difference in tension between the three types of yarns. Since each yarn is fed with a negative feed due to the difference in length, the circular garment machine used for knitting the circular knitted fabric A is fed with each yarn to each yarn feeder set in the knitting machine. In the middle, a yarn feeding device capable of switching between positive feeding and negative feeding is provided.

  5 and 6 show an example of the yarn feeding device 10 that enables switching between positive feeding and negative feeding. This yarn feeder 10 is based on the configuration of a Rosen type (AIRO type) yarn feeder, and a feed pulley 11 for controlling the feed by winding the yarn Y to be fed, and the outer periphery of the pulley 11. A pressing tape 12 that presses the yarn Y that is wound around the pulley 11 and fed. The feed pulley 11 rotates in synchronization with the operation of the knitting machine.

  In particular, the pressing tape 12 is provided so as to be in contact with the pulley 11 except for a part in the width direction on the outer periphery of the pulley 11, for example, a substantially half portion. A flipper 14 with a yarn introduction hole 13 for selectively guiding the yarn Y wound around the outer periphery of the pulley 11 to the portion 11a of the pressing tape 12 and the portion 11b other than the pressing tape 12 is provided. ing. The flipper 14 is pivotally supported at the end opposite to the side having the yarn introduction hole 13 so as to be swingable in the width direction of the pulley 11 (vertical direction in the figure), and the flipper 14 An output shaft 15a of advancing / retreating drive means 15 such as a cylinder is connected to be oscillated and displaced by the advancing / retreating operation of the advancing / retreating drive means 15, and by this oscillating displacement, a thread is passed through the yarn introduction hole 13. The formed yarn Y is provided so as to be selectively guided to the portion 11 a of the pressing tape 12 and the portion 11 b other than the pressing tape 12. That is, by the operation of the advance / retreat driving means 15, it is possible to select positive feeding in which the yarn Y passes through the portion 11 a of the pressing tape 12 and depolarization feeding in which the yarn Y passes through the portion 11 b other than the pressing tape 12. It is configured as follows.

  Reference numeral 16 in the drawing denotes a shaft support portion of the flipper 14. As the advance / retreat driving means 15, an air cylinder that can be operated instantaneously is preferably used. However, the present invention is not limited to this, and other cylinder devices or solenoids can also be used.

  Therefore, in the circular knitting garment machine for knitting the circular knitted fabric A of the present invention, the yarn knitting part 2 is knitted by using the yarn feeder 10 in the middle of feeding each yarn used for the knitting. In addition, the yarn feeding method can be switched according to the knitting of the body knitting portion 1.

  For example, when knitting the knitted knitted portion 2 composed of a bag knitting structure and a rib knitting structure having different yarn lengths, the yarns Y threaded through the yarn introduction holes 13 of the flippers 14 of the yarn feeding devices 10 are The yarn can be fed by depolarization feeding while keeping the portion 11b other than the pressing tape 12 on the outer periphery of the feeding pulley 11 passing therethrough. Then, at the time of tissue switching from the knitting part 2 to the knitting of the body knitting part 1, the flipper 14 is oscillated and displaced by the operation of the advancing / retreating drive means 15 such as the air cylinder. Each yarn Y passed through the yarn introduction hole 13 of the flipper 14 can be instantaneously switched to a state in which the portion 11a of the pressing tape 12 on the outer periphery of the feeding pulley 11 is passed. As a result, the body knitting portion 1 using three types of yarns of different materials can be knitted without any problem with a single knitted bare sheet knitting structure while actively feeding each yarn. This also makes it possible to make the tension of each yarn uniform and to improve the uniformity of the size of the stitches during knitting and the stability of the arrangement of the three types of yarns Y1, Y2, and Y3.

  Further, in the knitting of the bare tentacle knitting structure of the body knitting part 1, the three kinds of yarns of the front yarn Y1 and the back yarn Y3 and the elastic yarn middle yarn Y2, which are made of different materials, are maintained at a fixed position. Thus, it is necessary to feed the knitting needle portion of the lower cylinder. For this reason, the circular knitting garment machine used for knitting the circular knitted fabric A has at least three yarn paths as the yarn path constituting member disposed in the vicinity of the knitting needle row of the cylinder rotating at each yarn feeder. In addition, the three types of yarns Y1, Y2 and Y3 passing through the respective yarn paths must be held in a fixed arrangement and supplied.

Therefore, in the circular knitting garment machine for knitting the circular knitted fabric of the present invention , the yarn path constituting member 20 or 20a illustrated in FIG. 7 to FIG. 9 or FIG. 10 is used.

  The yarn path component 20 shown in FIGS. 7 to 9 has the following configuration. On the outer surface of the thick plate-shaped main body 21, that is, the surface opposite to the side facing the knitting needle row N of the cylinder, from the substantially central portion to the tip in the cylinder rotation direction (the direction of the white arrow in the figure) A yarn guide groove 22 that extends and opens at the tip is formed. The bottom portion of the guide groove 22 has a substantially V shape capable of keeping the yarn guided to the guide groove 22 in a certain arrangement state. A first yarn path R1 penetrating in the thickness direction (cylinder radial direction) from the outer surface to the inner surface (side surface facing the knitting needle row) is formed near the end of the guide groove 22 on the rear side in the cylinder rotation direction. Has been. A second yarn path R2 and a third yarn path R3 penetrating from the upper and lower surfaces of the main body 21 to the guide groove 22 are formed with their positions shifted in the cylinder rotation direction and the thickness direction. The two yarns passing through the second and third yarn paths R2 and R3 and exiting from the guide groove 22 to the knitting needle row N can be maintained at a certain position. Yes. That is, the second yarn path R2 is opened in the cylinder rotating direction from the third yarn path R3 and deeper than the third thread path R3 with respect to the guide groove 22. The yarn passing through the second yarn path R2 and passing through the guide groove 22 is always at a position inside the yarn passing through the third yarn path R3 and passing through the guide groove 22, that is, the guide groove 22 The yarn is guided through the bottom position of the V shape. As a result, the yarns guided through the first, second, and third yarn paths R1, R2, and R3 are moved from the first to the third to the knitting needle row N of the rotating cylinder. The yarn paths R1, R2, and R3 are fed in order and are locked to the knitting needles n while maintaining the arrangement state.

  Accordingly, in the knitting of the circular knitted fabric A according to the present invention, for example, the front yarn Y1 among the three types of yarns fed by positive feed by the above-described yarn feeder is used as the elastic yarn for the first yarn path R1. By feeding the middle yarn Y2 through the second yarn path R2 and the back yarn Y3 through the third yarn path R3 to the knitting needle portion, the yarns Y1, Y2 and Y3 are arranged in a fixed arrangement. The knitting needles n can be held while being kept in a state, and the knitting of the body knitting portion 1 can be knitted so as to form a three-layer structure with a bare tentacle knitting structure as described above. Reference numeral 24 in the figure denotes a support portion for the yarn path constituting member 20.

  In the knitting of the knitted knitted portion 2 of the circular knitted fabric A of the present invention, in addition to the three types of yarns Y1, Y2, Y3, the fourth yarn is the fourth yarn every other course of the rib knitting structure. Since there is a case where a covered yarn is added and knitted, in order to make this possible, out of the yarn feeders set in the knitting machine, every other one of the odd-numbered and even-numbered yarn feeders, For example, a yarn path constituting member 20a as shown in FIG. 10 capable of supplying the covered yarn can be used.

  In the yarn path constituting member 20a shown in FIG. 10, the thick plate-like main body 21 is elongated in the cylinder rotation direction (the direction of the white arrow in the figure). Basically, the same guideway 22 for the yarn path as that of the above-described yarn path constituting member 20 is formed on the outer surface, and the first thread path R1 is arranged in the same arrangement as that of the yarn path constituting member 20. A second yarn path R2 and a third yarn path R3 are formed.

  Therefore, when knitting the body knitting portion 1, the front yarn Y1 of the three types of yarn is used as the first yarn path R1, the middle yarn Y2 of the elastic yarn is used as the second yarn path R2, and By feeding the back yarn Y3 through the third yarn path R3 to the knitting needle portion, as described above, the yarns Y1, Y2, and Y3 can be guided to the knitting needles n while maintaining a constant arrangement state. It can be knitted to form a three-layer structure with a bare tengu knitting structure.

  In addition to the three yarn paths R1, R2, and R3, the yarn path constituting member 20a has an elongated hole extending in the cylinder rotation direction between the first yarn path R1 and the support portion 24. And a fourth hole R4 also serving as a yarn path through which a yarn catcher for catching the covered yarn Y4, which is the fourth yarn, can be protruded. A vacuum type yarn catcher (not shown) provided on the side protrudes from the elongated hole R4 and catches the covered yarn Y4 which is brought close to the elongated hole R4 by a yarn guide 25 such as a pipe as shown in FIG. The covered yarn Y4 can be fed through the elongated hole R4 by being drawn into the knitting needle portion. Accordingly, the covered yarn Y4 can be knitted together with the three types of yarns at every other yarn feeder, that is, every other course.

  As shown in FIG. 11, the yarn guide 25 for causing the covered yarn Y4 to project into the long hole R4 is made to approach the portion of the long hole R4 by a cylinder device 26 such as an air cylinder when the yarn guide 25 is caught by the yarn catcher. In this way, it should be easy to catch. Further, when the knitting portion 2 is finished knitting and the knitting of the body knitting portion 1 is started, as shown in FIGS. 11 and 12, the yarn guide 25 is moved instantaneously by the operation of the cylinder device 26. When the covered yarn Y4 is cut off and separated by a cutting device 27 such as a cutter operated by a cylinder device 28 such as an air cylinder between the yarn guide 25 and the yarn path constituent member 20a, apart from the constituent member 20a. Good. 27a and 27b in the figure show a scissors-type cutting blade that opens and closes with the shaft support 29 as a fulcrum. Each operation of the yarn catcher, the yarn guide 25, the cutting device 27 and the like for supplying the covered yarn Y4 can be instantaneously performed using the mechanical means and the electric means as described above. Set it.

Thus, the feeding course of the yarn to each yarn feeder, comprising a above-mentioned negative feeding and actively feed yarn feeding device switchable is possible, circular knitting with a yarn path components described above in further respective feeder By using a garment machine, the body knitting part 1 having a three-layer structure with a single knitted bare sheeting knitting structure and the mouth knitting part 2 consisting of a double knitting rib knitting structure and a bag knitting are stably knitted together. The present invention can be carried out satisfactorily.

  In the knitting of the circular knitted fabric A, the circular knitted fabric A knitted into a cylindrical shape is flattened while being flattened while being pulled through three winding rollers at the winding portion while being pulled. If you take it up or roll it down, there is a risk that a raw crease will remain on the circular knitted fabric. Is preferred. Further, it is preferable to control the contact pressure by forming a groove in a portion corresponding to the ear portion of one of the two rollers.
