Description

  The present invention relates to a continuous fabric and a knitting method thereof.

  When knitting a cylindrical (seamless) continuous fabric with a circular knitting machine, a piece knitting that repeats the knitting of the body part while forming a separation band of one to several courses at regular intervals in the longitudinal direction of the cylinder is well known. In many cases, the separation zone is knitted with hot melt yarn. In this piece knitting, it is also widely known that hem treatment is performed between the time when the separation band is knitted and the time when the body part starts to be knitted (for example, see Patent Documents 1 and 2).

  The part subjected to hem treatment (hereinafter referred to as “hem treatment part” in the present specification) is a part that becomes the hem of the garment when the garment is manufactured using this continuous fabric, and fits when the garment is worn. The main purpose is to impart the property and the prevention of elongation by washing. Hem treatment includes covering yarn such as single-covering yarn in which the outer periphery of core yarn such as polyurethane yarn is wound with a single covering yarn such as nylon yarn or double covering yarn in which coating yarn is double-wound, and cotton yarn for knitting the body part. It was normal to do this by knitting the yarn.

In the case of co-knitting, since both the covering yarn and the ground yarn appear on the surface side of the knitted fabric, the hem treatment portion is different in texture from the body portion at first glance. In addition, the covering yarn and the ground yarn appearing on the surface side as described above have a situation that a total of two or more dyeings are required due to the difference in dyeing property and the difference in the dye used.
There were also the following circumstances. For covering yarn, it is recommended that the length of the peripheral yarn is shorter than that of the ground yarn, and the stitches are made smaller (small loops). Is to be obtained. Therefore, the yarn feeder for feeding the covering yarn needs to be dedicated to the covering yarn because of the setting of the stitch (that is, it cannot be used as the yarn feeder for the ground yarn).

For example, in the case of a circular knitting machine with 16 yarn feeders, if four of the 16 yarn feeders are dedicated to covering yarn, the hem processing unit that performs knitting supports the number of yarns of covering yarn. The ground yarn is fed from the four yarn feeders, and the knitting is performed by feeding the total eight yarns, and the other eight yarn feeders are not fed during the hem processing.
In addition, when finishing the hem treatment and switching to the knitting of the body part next time, the yarn feeding was stopped (cutting the covering yarn) at the four feeding yarn dedicated yarn feeders, and then the yarn was not fed until then. The supply of the ground yarn is also started from the eight yarn feeders. That is, the body part is knitted by feeding yarns from a total of 12 yarn feeders, which is a combination of the eight yarn feeders and the four yarn feeders that supplied the ground yarn in the hem processing section. become. In other words, the covering yarn dedicated yarn feeder cannot be used during knitting of the body part.

  In a piece knitted tubular continuous fabric, the knitting of the yarn end is conspicuous at the knitting start position of the body part (boundary with the hem processing part) by switching to the knitting of the body part after knitting the hem processing part It sometimes appeared in the state. This knitting of the yarn end is often avoided by purchasers and wearers of clothing manufactured using this continuous fabric, and in some cases, the commercial value may be reduced.

  The knitting of the yarn end was largely caused by the occurrence of the tail end of the covering yarn on the fabric side due to the cutting of the covering yarn performed at the end of the knitting of the hem processing unit (the removal from the knitting point). Since the knitting of the yarn end is a phenomenon that occurs inevitably by knitting the hem treatment part before knitting the body part, the hem treatment itself can only be avoided. However, if the hem treatment is not adopted, there is a problem that it is impossible to obtain the fitting property when wearing clothes and the effect of preventing the elongation due to washing.

On the other hand, with regard to hem treatment, the use of cross-knitting has traditionally required two or more dyeings during clothing production, and the texture of the hem treatment part and body part when viewed as a whole garment. There were also problems such as different points. Furthermore, when the body part is knitted, there is a problem that the knitting efficiency is poor because the number of yarn feeders provided in the circular knitting machine cannot be utilized to the maximum extent.
The present invention has been made in view of the above circumstances, and as much as possible to prevent the yarn end knitting from appearing in a conspicuous state at the knitting start position of the body part, even when producing clothing, An object of the present invention is to provide a continuous fabric and a knitting method thereof capable of obtaining a high-quality and high-quality appearance.

  In addition, the present invention can reduce the labor of dyeing at the time of garment production, can provide a uniform feeling for the entire garment, and can improve the knitting efficiency of continuous fabrics as much as possible (maximizing the number of yarn feeders in a circular knitting machine) The object is to provide a continuous fabric and a knitting method.

In order to achieve the above object, the present invention has taken the following measures.
That is, the continuous fabric according to the present invention has a body part knitted via a separation band, and a polyurethane elastic yarn is attached to the ground yarn knitting the body part between the separation band and the body part. At least one course of the spliced yarn knitting structure portion knitted with the yarn is provided. The spliced yarn knitting is characterized by creating an appearance in which the surface of the knitted fabric is covered with a single yarn as if the metal was plated, and the so-called spliced yarn appears on the back surface of the ground yarn.

  The polyurethane elastic yarn is not particularly limited as long as it is an elastic yarn containing polyurethane, but the bare yarn (bare yarn) that is the polyurethane yarn as it is, and the single covering in which the nylon yarn is wound on the outer periphery of the core yarn made of the polyurethane yarn. Preferred are yarns, double covering yarns in which nylon yarns are double-wound, conjugate yarns in which polyurethane is the core and nylon is the sheath, and bare yarns (bare yarns) are particularly preferred.

  According to the spliced yarn knitting with the polyurethane elastic yarn that is the spliced yarn for the ground yarn, when switching to the knitting of the body part after finishing the spliced yarn, the supply of the polyurethane elastic yarn is stopped ( When cutting and removing the yarn from the knitting point, the feature that the tail end of the polyurethane elastic yarn easily enters the fabric (in the knitting structure of the ground yarn) can be advantageously used. Therefore, at the knitting switching position, the tail end of the polyurethane elastic yarn is less noticeable from the outside.

For these reasons, in this continuous fabric, it is possible to prevent as much as possible that the yarn end weaving appears conspicuously at the knitting start position of the body part. Therefore, the clothing manufactured using this continuous fabric can have a good quality and a high quality appearance.
A hem treatment section is provided over a plurality of courses between the separation band and the body part, and the above-mentioned splicing knitting (polyurethane elastic yarn is used as the ground thread) in a distributed arrangement of all the hem treatment sections or every several courses. The knitting to be added) may be knitted.

Needless to say, by providing the hem treatment portion in this way, the garment manufactured using this continuous fabric can be provided with a fit property at the time of wearing and a stretch prevention property by washing.
As described above, the heme processing part is in a state in which ground yarn mainly appears on the surface of the fabric as with the body part by performing splicing knitting, and there is almost no difference in appearance from the body part. Become. Therefore, the clothing produced using this continuous fabric is unified in the texture of the entire clothing (the body part and the hem), and the appearance is improved.

  In addition, when knitting a continuous fabric having such a configuration, the yarn feeder for feeding polyurethane elastic yarns may simply stop (cut) the polyurethane elastic yarns when knitting the body part. The yarn feeding can be continued as it is. That is, at the time of knitting the body part, the number of yarn feeders provided in the circular knitting machine can be utilized to the maximum, so that the knitting efficiency is increased as much as possible.

  Furthermore, at the time of producing clothing using this continuous fabric, the dyeing may be performed only for the body part. In other words, in the conventional hem processing section, since the knitting was performed using the covering yarn, an extra number of dyeings was required due to the difference in dyeability between the ground yarn and the covering yarn and the difference in the dye used. Since only the number of times the yarn is dyed is sufficient, there is an advantage that the production efficiency of the clothes is increased.

When a plurality of spliced yarn knittings are performed between the separation band and the body part, it is preferable that the splicing knitting is knitted so as to be in contact with the first course of the body part. Further, it is preferable that a spliced yarn is knitted on the first course following the separation band.
On the other hand, in the continuous fabric knitting method according to the present invention, a continuous continuous fabric is knitted using a circular knitting machine, and then a body portion is knitted using a ground yarn. In the knitting method, at least one course of splicing with polyurethane elastic yarn and ground yarn is performed after knitting of the separation band, and then the supply of the polyurethane elastic yarn is stopped and the body part is knitted.

  The continuous fabric and the knitting method thereof according to the present invention prevent the yarn end from appearing in a conspicuous state at the knitting start position of the body part as much as possible, and when the garment is manufactured, the quality is high and high. A quality appearance can be obtained. In addition, the labor of dyeing can be reduced during clothing production, the texture of the entire clothing can be unified, and the knitting efficiency as a continuous fabric can be increased as much as possible (maximizing the number of yarns supplied by the circular knitting machine) It becomes like this.

It is the perspective view which showed one Embodiment of the continuous fabric which concerns on this invention. It is the front view which showed an example of the clothing manufactured using the continuous fabric which concerns on this invention. It is front sectional drawing of a circular knitting machine.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an embodiment of a continuous dough 1 according to the present invention. The continuous fabric 1 is a cylindrical fabric that is seamless in the circumferential direction, and has a separation band 2 of one to several courses (the course direction corresponds to the circumferential direction of the cylindrical shape) at regular intervals in the longitudinal direction of the cylinder. It is formed and piece knitted.
The separation band 2 is knitted using hot melt yarn, and heat treatment such as spraying steam in the state of the continuous dough 1 causes the separation band 2 to be thermally fused, and the continuous dough 1 has a certain length. Can be divided into In the following description, the dough range taken out as a length excluding the separation band 2 is referred to as “piece material P”. Then, a single piece of clothing 3 as shown in FIG. 2 is produced from each piece material P thus taken out.

  In this embodiment, the piece material P has a body part 5 and a hem processing unit 6. When forming the hem of the garment 3, the hem treatment unit 6 performs hem treatment for imparting a fit property at the time of wearing and an anti-elongation property due to washing so as to obtain particularly abundant elasticity in the circumferential direction. It is the part which did. The knitting of the continuous fabric 1 is performed in the order of knitting the separation band 2, knitting the hem processing unit 6, and then knitting the body part 5.

The garment 3 illustrated in FIG. 2 is a round neck short sleeve type undershirt. The garment 3 is used as a body fabric by using the cylinder diameter of the piece material P as it is. Therefore, the continuous fabric 1 is a body size (a size that allows the cylinder diameter to be directly applied to the body cloth without cutting or sewing). ).
The hem processing unit 6 is formed by performing a splicing knitting with a polyurethane elastic yarn on a ground yarn such as a cotton yarn used for knitting the body part 5. The polyurethane elastic yarn is an elastic yarn containing polyurethane, for example, a bare yarn of the polyurethane yarn as it is, a single covering yarn in which the polyurethane yarn is a core yarn and a nylon yarn is wound around the outer periphery thereof, and the polyurethane yarn is a core yarn. And a double covering yarn in which nylon yarn is double-wrapped on the outer periphery thereof, and a conjugate yarn having polyurethane as a core and nylon as a sheath.

The hem processing unit 6 is formed by knitting a plurality of courses, and among these, the splicing knitting is knitted so as to be distributed all over the course or every several courses. In the first course following the separation band 2 (starting course of the hem processing unit 6) and the arrangement in contact with the first course of the body part 5 (final course of the hem processing unit 6), it is preferable that the splicing knitting is performed. .
In this way, when switching to knitting of the body part 5 after knitting the hem processing unit 6, even if the supply of the polyurethane elastic yarn is stopped (cut) at the end of the splicing knitting, the tail end of the polyurethane elastic yarn Has the advantage that it is easy to enter into the fabric (knitting structure of the ground yarn) and is less noticeable from outside the fabric. That is, at the knitting start position of the body part 5, it is possible to prevent as much as possible that the tail end of the polyurethane elastic yarn appears in a conspicuous state. Therefore, the clothes 3 manufactured using such a continuous fabric 1 can have a good quality and a high quality appearance.

  For knitting the continuous fabric 1, a double circular knitting machine 10 having a cylinder 11 and a dial 12 as shown in FIG. 3 is used. In this circular knitting machine 10, each needle tip portion (hook portion) of the cylinder needle 13 provided around the cylinder 11 and the dial needle 14 provided on the dial 12 is used for the integral rotation of the cylinder 11 and the dial 12. Accordingly, the knitting operation is performed while forming a plurality of knitting points (knitting points) 15 in the circumferential direction.

  Then, from a striper device (yarn supply switching device) 16 provided corresponding to each knitting point 15, a knitting is provided via a yarn feeder 17 provided corresponding to each finger portion equipped in each striper device 16. The yarn is fed to the ting point 15. Thus, the continuous fabric 1 is knitted into the cylinder 11 in response to the knitting at each knitting point 15 and wound by the winding device 18 below the cylinder 11.

Next, a knitting method for knitting the continuous fabric 1 with the circular knitting machine 10 will be described.
A case where the circular knitting machine 10 is provided with 16 yarn feeders 17 is exemplified. First, the cylinder 11 and the dial 12 are integrally rotated and discarded, and then the hot melt yarn is fed from one yarn feeder 17 to knitting the separation band 2 of one to several courses.
For example, polyurethane elastic yarn is fed corresponding to 8 yarn feeders 17 out of 16 yarn feeders 17 for feeding ground yarn. In this way, for example, the hemming section 6 of about 70 courses is formed while splicing knitting yarns are distributed and arranged every other course.

Thereafter, all the supply of polyurethane elastic yarn is stopped (cut), the yarn is removed from the knitting point 15, and the body part 5 is knitted with the ground yarn supplied from the 16 yarn feeders 17.
In this manner, the spliced yarn knitted portion is also in a state in which the ground yarn mainly appears on the surface of the fabric in the same manner as the body portion 5, and there is almost no difference in appearance from the body portion 5. Therefore, in the case where the hem processing unit 6 is formed by knitting a plurality of spliced yarns, the texture of the garment 3 as a whole is unified and the appearance is improved.

  In addition, in the yarn feeder 17 for supplying polyurethane elastic yarn when performing splicing knitting, it is only necessary to stop (cut) the polyurethane elastic yarn when knitting the body part 5, and the ground yarn is supplied as it is. You can continue. That is, when the body part 5 is knitted, the number of yarn feeders 17 provided in the circular knitting machine 10 can be utilized to the maximum, so that there is an advantage that the knitting efficiency can be increased as much as possible.

  Further, in the process of manufacturing the garment 3, the number of dyeings for the body part 5 is sufficient. That is, in the past, since the knitting using the covering yarn was performed, an extra dyeing for the covering yarn was necessary. Manufacturing efficiency can be increased.

Hereinafter, embodiments will be described in more detail using examples. The present invention is not limited to this.

In Example 1, a cotton course yarn of 50 courses was used as a ground yarn, a 56-dtex bare polyurethane yarn was added as a splicing yarn, and a 64 course spliced knitting was knitted to form a hem treatment portion.
(Example 2)
In Example 2, a 50th cotton yarn was used as a ground yarn, a 78 dtex polyurethane yarn was used as a core yarn, and a single covering yarn in which a 33 dtex nylon yarn was wound around the outer periphery was added to the ground yarn as a supplementary yarn. A spliced yarn was knitted to form a hem processing section.
(Example 3)
In Example 3, a 50th cotton yarn was used as a ground yarn, a 78 dtex polyurethane yarn was used as a core yarn, and a double covering yarn obtained by double winding a 33 dtex nylon yarn around the outer periphery was added to the ground yarn as a supplementary yarn. The knitting course yarn was knitted to form a hem processing section.
Example 4
In Example 4, a 50-course cotton yarn was used as the ground yarn, and a 56-decitex conjugate yarn with polyurethane as the core and nylon as the sheath was added to the ground yarn as a spliced yarn, and a 64 course spliced yarn was knitted to form a hem. A processing part was formed.
