Description

  The present invention relates to a tubular fabric part and an underwear production method for producing an undergarment such as pants and girdle using the tubular fabric part.

Underwear type underwear such as girdle and shorts is made by sewing fabric parts cut into various required shapes and making them together (implementing a so-called “cut-and-sew” manufacturing method) Is common.
However, the underwear produced by this method has various sewn lines, causing problems such as touching the skin among people with sensitive skin, and the sewn line resonating with the outer and making it look bad. There is. Furthermore, above all, problems such as the cutting and sewing of fabric parts requiring man-hours and the need for skill in these operations have been pointed out, and it was difficult to reduce the production cost.

Therefore, using a cylindrical fabric as the material, one opening is made to correspond to the waist part, and the other opening is sewn in the front and back of the center part, and the two small openings generated on both sides of this sewn part are leg holes. Thus, it has been proposed to produce underwear such as a girdle (see Patent Document 1).
Japanese Utility Model Publication No. 5-62510

Even in a conventionally known method (Patent Document 1) for producing underwear such as a girdle using a tubular fabric as a raw material, the sewing work is indispensable in the end. For this reason, contact obstacles caused by the sewing line, adverse effects on the outerwear, increased production costs due to difficulty in production, etc. have not yet been resolved.
The present invention has been made in view of the above circumstances, and when manufacturing underwear, it is possible to eliminate and remove contact obstacles caused by the sewing line and adverse effects on the outer part with certainty. An object of the present invention is to provide a tubular fabric part and an underwear manufacturing method that can reduce the manufacturing cost.

In order to achieve the above object, the present invention has taken the following measures.
That is, the cylindrical fabric part according to the present invention has an opening at each end on both sides, and the cylindrical main body is formed in a state where the both ends are connected in a continuous cylindrical shape. The standard knitting portion serving as a reference for the stitches and the stitching knitting portions knitted with the stitches in the cylinder axis direction as compared with the standard knitting portions are arranged in a circumferential direction.
In the cylindrical fabric parts having such a configuration, the standard knitted portion side is longer and the knitted knitted portion side is shorter than the standard knitted portion, because the knitted portion is clogged in the cylinder axis direction. The whole is curved.

With this tubular fabric part, for example, by simply forming a central opening in the standard knitted portion of the tubular main body, a lower garment type underwear is produced with the central opening as the waist and the openings at both ends as the hem. be able to. In this case, the stitched knitting portion forms a crotch portion.
In this way, it is possible to produce a garment type undergarment without requiring sewing. That is, since the sewing is unnecessary, it is possible to almost certainly eliminate and eliminate the contact failure caused by the sewing line and the adverse effect on the outer. In addition, since the manufacturing is easy, the manufacturing cost can be reduced. In addition, when this manufacturing method is carried out, there are advantages that sewing thread chips are not generated, and that fabric cutting scraps are eliminated or minimized.

In addition, since the knitted part is an area that is knitted with the same degree, the fabric volume is increased compared to the standard knitted part, and the feeling of touch becomes softer, and the movement of the wearer is flexibly followed. Therefore, it is also provided with moderate stretchability (stretchability suppressed to some extent than the standard knitted portion). Absorbency and heat retention are also abundant. Therefore, this knitted knitted portion is convenient for forming the crotch part.
The tubular fabric parts according to the present invention are not limited in use as an undergarment-type undergarment producing action. For example, when producing underwear for an upper garment (such as a shirt), it can be attached to the shoulder portion of the body to form a cuff.

The knitted portion may be knitted by repeating a welt or a plurality of times of tucking over a plurality of courses across a loop. Further, the knitted knitted portion can be arranged in a strip shape that is long in the cylindrical axis direction with respect to the cylindrical main body portion, or can be arranged in a partial arrangement in the cylindrical axis direction with respect to the cylindrical main body portion.
Furthermore, it is only necessary to provide a terminal processing unit that is endless around the opening at both ends of the cylindrical main body. The knitting structure in the terminal processing unit is not particularly limited.
Any of these configurations can be provided by a knitting method that can be adopted during the knitting process of the cylindrical fabric parts by the circular knitting machine. That is, it is possible to provide an additional configuration of the cylindrical fabric part without requiring any further labor. These additional configurations further facilitate the manufacture of the undergarment-type underwear using the cylindrical fabric parts and increase the degree of completion as a product.

On the other hand, in the underwear manufacturing method according to the present invention, the cylindrical main body is formed in a state in which there is an opening at each end on both sides and the two end portions are connected in a continuous cylindrical shape. A cylindrical fabric part, in which the standard knitting part that is the reference for the stitches and the knitted stitching part that is knitted with the stitches in the cylinder axis direction compared to the standard knitting parts, are separated in the circumferential direction. By knitting with a knitting machine and providing a central opening in the standard knitting part with respect to the cylindrical main body part of this cylindrical fabric part, the central opening is made a waist part, and the openings at both ends are made hems, Produce underwear type underwear.
Thus, since the undergarment type undergarment can be manufactured without the need for sewing, it is possible to almost certainly eliminate and eliminate the contact obstruction caused by the sewing line and the adverse effect on the outer. In addition, since the manufacturing is easy, the manufacturing cost can be reduced. In addition, there is an advantage that sewing thread chips are not generated, and that there is no or minimal fabric cutting waste.

A waist band may be attached along the periphery of the opening to the central opening for waist formed in the standard knitted portion of the cylindrical main body.
When knitting a cylindrical fabric part, it is preferable to perform a terminal treatment along the opening peripheral portions of both ends of the cylindrical main body portion.
As a result, the production of the underwear-type undergarment becomes easier and the degree of completion as a product is enhanced.

  With the tubular fabric parts and the underwear manufacturing method according to the present invention, when the underwear is manufactured, it is possible to almost certainly eliminate and eliminate the contact obstacles caused by the sewing line and the adverse effects on the outer. The cost can be reduced.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
3 and 4 show a first embodiment of a tubular fabric part 1 according to the present invention, and FIGS. 1 and 2 are lower garment types (FIG. 1) produced using this tubular fabric part 1. The example shows underwear 2 of shorts).
As shown in FIG. 3, the cylindrical dough part 1 according to the present invention has an opening 5a at each end portion 5 on both sides, and the cylindrical main body portion 6 is connected in a continuous cylindrical shape between the both end portions 5. It has been formed. The cylindrical main body 6 is in a state in which the cylindrical axis direction is curved unless a load is applied to pull the both ends 5 in the cylindrical axis direction. At this time, the both ends 5 are not parallel.

The tubular main body 6 is knitted using a circular knitting machine so that the entire tubular body has an integrated structure (seamless configuration in the circumferential direction) without sewing or adhesion. Further, in the circumferential direction of the cylindrical main body portion 6, the standard knitting portion 7 and the stitched knitting portion 8 are arranged separately from each other by different knitting methods.
The standard knitting portion 7 is an area knitted as a general knitted fabric such as a flat knitted fabric or a rubber knitted fabric, and when the undergarment 2 is produced using the tubular fabric part 1, It is used to form a reference area (area occupying most).

On the other hand, the stitched knitted portion 8 is an area knitted with a degree in the cylinder axis direction as compared with the standard knitted portion 7, and is stretchable, water-absorbing, and heat-retaining in the body fabric. It is used to form a region that enhances the function.
For example, as shown in FIG. 1 and FIG. 2, when the undergarment type underwear 2 such as a girdle or shorts is manufactured using the tubular fabric part 1, the crotch portion 8 is formed by the stuffed knitting portion 8, The region is formed by the standard knitting portion 7.
In this case, the knitted knitted portion 8 is formed in a band-like arrangement that is long in the cylindrical axis direction at one circumferential position (for example, about 60 °) in the cylindrical main body portion 6 and is formed by a standard knitted portion in which other regions are continuous. What should be done.

As a specific knitting method of the knitted knitted portion 8, as shown in FIG. 4, for example, welt is performed several times (FIG. 4 illustrates a knitted structure that is repeatedly welded twice in the course direction. It is preferable to weld 3 to 20 times, etc.) to repeat a loop over a plurality of courses. In this embodiment, knit after 15 welts in the course direction is repeated over 3 wales, and in the next wale, a knitted structure knit on all courses (4 wales and 16 course repeats), and good results are obtained. ing.
In multi-time welts, loops formed across multiple courses produce an anti-stretching action that limits the stretchability in the wale direction (the direction perpendicular to the course direction) and a tightening action that shrinks the wale direction. Let These expansion and contraction suppressing actions and tightening actions serve to shorten the length in the cylinder axis direction of the knitted knitted portion 8 (see arrow X in FIGS. 3 and 4). The cylindrical main body 6 is curved as a whole as described above, because the knitted knitted portion 8 is arranged in a strip shape in this way, and the knitted knitted portion 8 has an effect of shortening the length in the cylinder axial direction. The main reason is that it is generated.

If it is repeated three times or less in the course direction, the effect of clogging is low, and it is difficult to form the curved shape of the tubular fabric part 1. In addition, if it is repeated 20 times or more, the strength of the yarn may be lost due to the tension of the clogging, and the yarn may break or the knitting may become difficult.
In addition, it is only necessary to provide endless terminal processing portions 10 in the circumferential direction at both end portions 5 of the cylindrical main body portion 6 so as to prevent fraying around the opening 5a and to improve the feel and appearance. . The terminal processing unit 10 may be a so-called makeup process in which a bag knitting part is provided at the beginning of knitting or at the end of knitting when batch manufacturing (a method in which a manufacturing process is repeated for each product) is performed. Alternatively, a fraying prevention function may be imparted by weaving molten yarn and then fusing it.

The cylindrical fabric part 1 having such a configuration is knitted by a circular knitting machine using, for example, SCY or the like using a 20 denier polyurethane yarn as a core and a 50 denier nylon as a sheath. When knitting 8, the needle selector is operated so that the knitting needle is held in the welt position.
The thread type to be used is not limited to the above, and a single material thread such as synthetic fiber (polyester, nylon, etc.), semi-synthetic fiber (rayon, etc.), natural fiber (cotton, wool, silk, etc.) may be used. However, in order to form a knitted portion by welting a plurality of times, it is necessary to form a knitted fabric including elastic yarn at least in the knitted portion, such as polyurethane yarn and spliced knitting.

In order to manufacture the undergarment-type undergarment 2 after the knitting of the tubular fabric part 1, a central opening 12 is formed in the standard knitted portion 7 of the tubular main body portion 6 as shown in FIG. The central opening 12 is used as a waist portion. That is, simply by providing the central opening 12, the underwear 2 having the openings 5a at both ends 5 of the cylindrical main body 6 as the hem and the cuffed knitting 8 as the crotch can be easily manufactured.
In the circumferential direction of the cylindrical main body 6, the relative positional relationship between the central opening 12 and the stitched knitted portion 8 is such that the central opening 12 is slightly biased forward from the center of the stitched knitted portion 8 ( α °> β °) is preferable.

If necessary, a waistband 13 formed of a lace fabric or a rubber material may be attached along the periphery of the central opening 12. The waistband 13 may be attached by sewing or adhering (welding, bonding, etc.).
Of course, the attachment of the waist band 13 is not limited, and the central opening 12 can be used as a waist part as it is. In this case, at the stage where the tubular fabric part 1 is knitted, the formation planned position of the central opening 12 may be knitted as a knitted fabric or a melted yarn may be knitted.

  Since the undergarment 2 can be produced without the need for sewing in this way, the produced undergarment 2 can almost certainly eliminate and eliminate contact obstructions caused by the sewing line and adverse effects on the outerwear. It can be done. Further, since the manufacturing becomes extremely easy, the manufacturing cost can be reduced. In addition, even if there is a case where sewing is adopted for the attachment of the waistband 13, the sewing location is limited to an extremely small range as compared with the case where all production of the underwear 2 is performed by sewing, It can be said that the removal and removal of various problems caused by the sewing line can be sufficiently obtained.

In addition, when this manufacturing method is carried out, there is an advantage that sewing thread chips are not generated, and fabric cutting scraps can be minimized. In addition, since the stitched knitting portion 8 is an area knitted with knitted stitches, the fabric volume is increased compared to the standard knitting portion 7, and the touch feeling becomes softer and the movement of the wearer is flexible. It is also provided with moderate stretchability (stretchability suppressed to some extent than the standard knitted portion) that can follow. In addition, since the knitted knitted portion 8 is rich in water absorption and heat retaining properties, it is convenient for forming the crotch part.
By the way, as shown in FIG. 6, the hem extension fabric 15 may be attached to both end portions 5 of the cylindrical main body portion 6.

Instead of “attaching” the hem extension fabric 15, the hems from both ends of the cylindrical main body 6 may be extended by knitting. Thereby, the trouble of retrofitting can be eliminated. In this case, since the overall length of the cylindrical main body portion 6 is long, the knitted knitted portion 8 is a partial arrangement in the cylindrical axis direction with respect to the cylindrical main body portion 6.
[Second Embodiment]
FIG. 7 shows a second embodiment of the tubular fabric part 1 according to the present invention, and FIG. 8 shows the manufacture of an upper garment type (shirt example) undergarment 2 using the tubular fabric part 1. The process is shown.

The cylindrical dough part 1 of the second embodiment is formed so that the length in the cylindrical axis direction of the cylindrical main body portion 6 exceeds the shoulder width. Two places and the knitting part 8 are provided. Almost all other regions in the cylindrical main body 6 are standard knitted portions 7. That is, in the second embodiment as well, the tubular main body 6 has a long overall length, and the places where the stitched knitting portions 8 are required are dispersed. On the other hand, it is a partial arrangement in the cylinder axis direction.
In order to manufacture the upper garment-type undergarment 2 using the tubular fabric part 1 having such a configuration, a lower opening 20 is provided at the center between the knitted knitted parts 8, and the lower opening 20 is in the circumferential direction. An upper opening 21 is provided at a position on the opposite side. The lower opening 20 is used for connection to a body cloth 22 formed of a tubular cloth or the like, and the upper opening 21 is used as a neckline as an undergarment 2.

The method for forming the lower opening 20 and the upper opening 21 is the same as the method for forming the central opening 12 described in the first embodiment. The method for connecting the body cloth 22 to the lower opening 20 is the same as the method for attaching the waistband 13 described in the first embodiment.
[Third Embodiment]
FIG. 9 shows a second embodiment of the tubular fabric part 1 according to the present invention, and an underwear 2 of an upper garment type (illustration is a shirt) manufactured using the tubular fabric part 1.
The cylindrical fabric part 1 of the third embodiment is unprocessed on the assumption that one end portion 5 of the cylindrical main body 6 is attached to the body fabric 25 (the terminal processing unit 10 is replaced with a non-processed portion). Not provided). Others are the same as the first embodiment. An upper garment type undergarment 2 is manufactured by attaching the cylindrical fabric part 1 having such a configuration to both shoulder sleeves of the body fabric 25.
[Others]
The present invention is not limited to the above-described embodiments, and can be appropriately changed according to the embodiments.

  For example, as a knitting method of the knitted knitting portion 8, as shown in FIG. 10, a plurality of times of tucking (FIG. 10 illustrates a case of tucking twice) etc. You may make it let it.
