JP4510775B2 - Bottom wear - Google Patents

Description

  The present invention relates to bottom wear mainly knitted by a circular knitting machine, and particularly to bottom wear used as underwear for sports.

In recent years, various types of sports bottom wear have been proposed in which the leg muscles are partially pressed to increase mobility.
As an example, as described in Patent Document 1, resin or rubber is attached to a knitted fabric portion that presses a muscle, or a knitted fabric portion reinforced by a cut boss is formed. The thing (patent document 2) is known.

  However, in the case where a resin or rubber is applied to the knitted fabric portion that presses the muscle, the resin or rubber is attached to the work, which reduces productivity and increases the cost. There was a problem that the rubber sticking on the surface was unsatisfactory and the product value was low.

On the other hand, in the case where the knitted fabric portion reinforced by the cut boss is formed, not only the labor for cutting the crossover yarn portion is required, but the productivity is lowered and expensive, and the cut crossover yarn portion is not limited. There was a problem that the yarn was wasted and the yield was poor.

  The present invention, as bottom wear for sports, such as bottom wear, can provide high-commodity bottom wear that is easy and inexpensive to enhance the mobility by partially pressing the leg muscles. The purpose is to be able to.

In order to achieve the above object, a bottomware manufacturing method according to the present invention is a bottomware manufacturing method in which left and right legs are formed and integrated by sewing on a cylindrical knitted fabric knitted by a circular knitting machine. In forming the stretch-suppressing knitted fabric portion on a part of the bottom wear, the knitted fabric portion is knitted at the time of knitting at least a portion of the knitted fabric excluding the joint knitted fabric on the side that extends during bending and stretching movements . A crimped yarn that appears on the front side, an elastic yarn such as FTY that appears on the back side, and a hot-melt adhesive yarn that is inserted inside the knitting needle, and a crimped yarn that appears on the front side and an elastic yarn such as FTY that appears on the back side. Furthermore, after forming the stitches of the stretch-suppressing knitted fabric portion with a hot-melt adhesive yarn on the inside and knitting into a cylindrical shape, before forming the cylindrical knitted fabric into bottom wear by sewing, or the cylindrical knitted fabric The bottom wear by sewing By heat treatment after molding, the structure of the knitted fabric formed by the elastic yarn that melts the hot-melt adhesive yarn to form the knitted fabric of the part is consolidated to form the stretch-suppressed knitted fabric portion This is the main feature.

The bottom wear according to the present invention is a bottom wear in which the left and right legs are formed by a cylindrical knitted fabric knitted by a circular knitting machine and integrated by sewing , and a stretch-suppressing knitted fabric portion is part of the bottom wear. The stretch-suppressing knitted fabric portion is composed of a crimped yarn that appears on the front side and an FTY that appears on the back side when knitting at least a portion of the knitted fabric excluding the knitted fabric of the joint portion that becomes the side that stretches during bending and stretching movements, etc. The knitted yarn made of elastic yarn and the hot melt adhesive yarn inserted inside the knitting yarn in addition to the knitting yarn form a stitch of the knitted fabric portion, and the hot melt adhesive yarn located inside the cylindrical knitted fabric is heat treated. The structure of the tubular knitted fabric knitted by the crimped yarn appearing on the front side and the elastic yarn such as FTY appearing on the back side is consolidated to form the stretch-suppressing knitted fabric portion. It is the main feature.

According to the present invention, at the time of knitting at least a portion of the knitted fabric excluding the knitted fabric of the joint portion on the side that extends when the bottom wear is formed by integrating the tubular knitted fabric by sewing, together with the elastic yarn for knitting knitted fabric After inserting the hot-melt adhesive yarn and knitting into a tubular shape, before forming the tubular knitted fabric into bottom wear by sewing, or by heat-treating after forming the tubular knitted fabric into bottom wear by sewing The knitted fabric made of elastic yarn that melts the hot-melt adhesive yarn to form the knitted fabric of the relevant part is consolidated to maintain the balance between the abdominal and back muscles and ensure blood circulation from the Achilles tendon For example, the bottom wear is a bottom wear for sports (underwear), while maintaining the balance between the abdominal muscles and the back muscles. Tendons, it is possible to ensure circulation of the calf portion.
Thereby, when the blood flow in the calf portion is stagnated and swollen, blood circulation is further deteriorated, and the conventional problem that the mobility of the foot is further impaired can be solved.

  In addition, when knitting a knitted fabric in a region where it is necessary to press muscles, the hot-melt adhesive yarn inserted during the yarn feeding is melted by heat treatment, and the knitting yarn in the vicinity thereof is bonded and fixed. There is also an advantage that the resin and rubber adhered to the knitted fabric portion that presses the knitting muscles like those of No. 1 does not appear and has a good appearance and high commercial value.

  Furthermore, unlike the conventional knitted fabric part reinforced with cut bosses, the hot-melt adhesive yarn inserted in the yarn supply is melted by heat treatment, and the adjacent knitting yarn is bonded and fixed. This makes it possible to easily and inexpensively provide bottomware with a high commercial value and a high-quality product without increasing the work required to cut the crossover portion.

  In order to achieve the above object, preferred embodiments of bottom wear according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view of underwear (so-called tights), which is bottomwear for sports according to the present invention, FIG. 2 is a rear view of the underwear, and reference numeral 1 generally indicates the underwear.
The underwear 1 includes three members, left and right leg parts 2a and 2b, and a gusset part 3 interposed in the crotch part where the leg parts 2a and 2b are combined.

Each of the leg parts 2a and 2b is formed in a cylindrical shape by a circular knitting machine, and the circular knitting machine in this example has a yarn feeder (yarn feeder) 5 with respect to the rotating cylinder 4 as shown in FIG. 4 pieces are provided, which is highly productive so that four courses can be knitted with one rotation of the cylinder. In the vicinity of each yarn feeder 5, a cut end portion of a hot-melt adhesive yarn described later is sucked and held. A holding portion 6 is provided.

Each of the leg parts 2a and 2b includes a knitted fabric portion A that is restrained from stretching to press the muscle, and a joint portion 7 that is on the side that stretches during, for example, bending and stretching, and a portion that does not require pressing of the muscle. When the knitted fabric part B such as 8 is freely stretched and is knitted from the ankle part 9 toward the waist part 10, first, the end of the ankle part 9 is knitted with a predetermined number of stitches. It is knitted while forming the tightening portion C.
In the calf portion 11, the number of stitches is increased gradually or stepwise to increase the diameter of the tubular knitted fabric of the leg parts 2 a and 2 b, and the waist portion that ends the knitting from the knee joint portion 12 through the hip joint portion 13 (Mouth) Up to 10 is formed in a cylindrical shape.
The knitted fabric of the waist portion 10 at the end of knitting is pearl knitting (garter knitting), and the end edge of the knitted fabric is sewn to the inner surface of the tubular knitted fabric, so that the cross-section of the string threaded portion ( Belt part) 14 is formed.

As shown in FIG. 4A, the knitted needle portion B of the cylinder 4 is a knitted fabric portion B such as the joint portion 7 that becomes the side that extends when the leg parts 2 a and 2 b formed into a cylindrical shape are bent and stretched as described above. 15, the knitting yarn 16 appearing on the front side and the knitting yarn 17 appearing on the back side (inward side of the tubular knitted fabric) are supplied and knitted. As the knitting yarns 16 and 17 appearing on the front side or the back side, a knitting yarn made of elastic yarn such as crimped yarn or FTY is used.
The knitting yarn knitting the knitted fabric portion A whose elongation is suppressed to press the muscle is a knitting yarn 16 made of an elastic yarn such as crimped yarn or FTY appearing on the front side or the back side as shown in FIG. 4B. In addition to 17, a hot melt adhesive yarn 18 is added.
It goes without saying that the insertion density of the hot melt bonding yarn 18 may be inserted continuously or at predetermined intervals.
An example of the hot melt adhesive yarn 18 is Toray Industries, Inc. trade name “Elder (registered trademark) yarn”.

When the knitting becomes a knitted fabric portion B that is free to expand and contract, such as the joint portion 7 that extends from the knitted fabric portion A, which is restrained to stretch due to pressing the muscles, and the portion 8 that does not require muscle pressing. The hot melt adhesive yarn 18 is cut by a cutting means (not shown), and its end is sucked and held by the holding portion 6.
When the cylindrical knitted fabric of the leg parts 2a and 2b knitted into a cylindrical shape is removed from the circular knitting machine and heated for molding, it is made of elastic yarn such as crimped yarn or FTY that appears on the front side or the back side. The hot-melt adhesive yarn 18 fed together with the knitting yarns 16 and 17 is melted, and the structure of the knitted fabric knitted with the elastic yarns 16 and 17 such as crimped yarn and FTY appearing on the front side or the back side is bonded. Fix it.

Thus, the melted hot-melt adhesive yarn 18 does not appear inside or outside the cylindrical knitted fabric of the leg parts 2a and 2b, and the structure of the knitted fabric made of elastic yarn such as crimped yarn or FTY is a hot-melt adhesive yarn. Since it is firmly fixed by the melting of 18, the knitted fabric with a beautiful appearance and high commercial value.
After that, in a state in which one side portion of the tubular knitted fabric of the two leg part parts 2a and 2b is cut open, the cut open portions face each other, and the knitted fabric for the gusset portion 3 is interposed at the lower end portion. When the sewing is performed, underwear (so-called tights) 1 which is sports bottom wear is completed.

In the above embodiment, the hot-melt adhesive yarn 18 is melted at the time of molding after the tubular knitted fabric of the leg parts 2a and 2b is knitted, and the knitted fabric structure of the portion is bonded and fixed. However, the present invention is not limited to this, and the hot melt adhesive yarn 18 is melted at the time of heat setting after sewing, and the knitted fabric structure of the part is adhered and fixed. Of course, the knitted fabric structure may be bonded and fixed by melting 18.
Of course, the present invention is not limited to sports bottom wear, and can be applied to underwear for correction.
