BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail.

The present invention is a garment having a single-use breast cup without darts, and particularly, a single breast cup (a breast-shaped core material). A fiber sheet that achieves this can be formed by deep drawing, is thin, light, and can adapt well to body movements. further,
It has the characteristic that it can be dyed freely to the desired color and it is difficult to lose its shape due to long-term wearing or repeated washing.

According to the constitution of the present invention, the fibers used in the breast cup are at least polyester fibers, the degree of amorphous orientation is 0.35 or less, preferably 0.30 or less, and the apparent Young's modulus is 1960 N / mm ² or less. , Preferably 980N
/ Mm ² or less. In any case, when the value exceeds this value, followability in molding is insufficient, and uniform deep drawing cannot be performed.

The height of the cup is 40 mm or more, preferably 50 mm or more, and the width is 80 mm or more, preferably 9 mm or more.
It has a three-dimensional curved surface of a breast shape of 0 mm or more.
This indicates that uniform deep drawing that is not possible with the prior art is possible, and in a breast cup, the core material for maintaining the shape of the cup is a single piece that is not used in combination with other fabrics. It is also possible to provide a breast cup that can widely correspond to the size of the breast and that can beautifully express the shape of the breast.

As the polyester fiber referred to in the present invention, aromatic polyesters such as polyethylene terephthalate, polybutylene terephthalate, and polypropylene terephthalate can be preferably used, and polyethylene terephthalate can be particularly preferably used. Further, a copolymer in which polyethylene terephthalate is copolymerized with polyalkylene glycol or a copolymer in which polyethylene terephthalate is copolymerized with 5-sodium sulfoisophthalic acid can be preferably applied.

Further, the thickness of the cup is 0.5 to 2.0 m
m is preferably 0.8 to 1.5 mm and the thickness variation is 3
Even if the fiber sheet is as thin as 0% or less, preferably 20% or less, the difference in thickness is extremely small.

Here, the degree of amorphous orientation of the polyester fiber is a value measured by the following method.

Measurement method: polarized fluorescence method Apparatus: FOM-1 manufactured by JASCO Corporation Optical system: transmission method (excitation light wavelength: 365 nm, fluorescence wavelength:
(420 nm) Measurement system: Rotation was performed using a polarizer 偏光 analyzer and a polarizer〓analyzer to obtain an angular distribution of in-plane polarized fluorescence intensity (I‖, I〓). Here, ‖ indicates parallel, and 〓 indicates vertical. The degree of amorphous orientation was determined by a uniaxial orientation coefficient f ² from the following equation.

F ² = 3/2 [{I {(0) + 2I}}
(0)｝ / K- ／] where K = {I‖ (0) + 4I〓 (0) + 8 / 3I‖
(90)｝ I‖ (0): ‖Measured relative polarized fluorescence intensity in the axial direction I‖ (90): ‖Measured relative polarized fluorescence intensity in the orthogonal direction to the above I〓 (0): 〓Measured The relative polarized fluorescence intensity in the axial direction The apparent Young's modulus is JIS-L-1013, 7.1.
It is a value measured according to 0.

The height of the breast cup referred to in the present invention is the length (H) from the bottom to the top as shown in FIG. 1 by cutting or hollowing out only the cup portion from the formed fiber sheet. The width of the breast cup is also the shortest inner diameter (W) between the cup bottoms.

The thickness of the breast cup was measured using a thickness gauge (trade name "PEACOCK" manufactured by Ozaki Seisakusho).
The thickness at zero point was measured without bias, and the average value of the thickness and the maximum value of the thickness variation were calculated by the following formula.

Average thickness (mm) = total thickness (m
m) / number of measurements (n) Thickness variation rate = (thickness of each part / thickness average value) × 10
0 The reason why the present invention adopts a dartless breast cup will be described with reference to a bra. As shown in FIG. 2, the seam does not exist in the cup portion, the skin is not rubbed due to the unevenness of the seam portion, the breast fits well, and the feel is good. In addition, when sweating due to sports or the like is involved, the air permeability and the moisture permeability are good, and there is excellent comfort. It is also advantageous in terms of strength, and has favorable durability against large and violent movements during wearing and repeated washing.

Needless to say, the configuration of the present invention, which is a single-piece use without darts, can save labor in the sewing process and contribute to labor saving and cost reduction.

The polyester fiber constituting the breast cup may be in the form of a staple or a filament, but is preferably in the form of a filament in view of durability against repeated washing and ease of dyeing. desirable.

One preferred embodiment of the present invention is a garment having a single-use breast cup having no darts, wherein the breast cup has at least an amorphous orientation degree of 0.3.
5 or less, a polyester fiber having an apparent Young's modulus of 1960 N / mm ² or less, and an amorphous orientation degree of 0.4 or more;
As a mixed fiber with a polyester fiber having an apparent Young's modulus of 2960 or more (a polyester fiber having a high degree of amorphous orientation and high apparent Young's modulus), such as a aligned yarn, an air entangled yarn, a twisted yarn, and a twisted yarn. Use, height 40mm or more, width 80m
m or more, the thickness is 0.5 to 2.0 mm, and the thickness change rate is 30% or less.

Here, the difference from the above is that one of the polyester fibers has an amorphous orientation degree of 0.45 or more, preferably 0.55 or more, particularly preferably 0.60 or more.
Apparent Young's modulus is 2940 N / mm ² or more, preferably 3
430 N / mm ² or more, particularly preferably 3920 N / m
It is to use a mixed fiber using polyester fibers having a m ² or more in combination.

The reason for this is that by using two or more types of polyester fibers having different degrees of amorphous orientation and apparent Young's modulus, both polyester fibers are exposed on the surface of the breast cup and their coloring properties are different. This is because a high-quality hue having a natural appearance can be suppressed and a swelling is developed in the internal structure of the fiber sheet, so that a soft and comfortable breast cup can be obtained.

As for the thickness of the polyester fiber, it is preferable that all or any of the polyester fibers is an ultrafine fiber of 2 dtex or less, preferably 1 dtex or less. In particular, it is particularly preferable that the polyester fiber having a high degree of amorphous orientation and a high apparent Young's modulus is thin from the viewpoint of feeling with the skin.

Further, since the breast cup of the present invention is composed of polyester fiber, it can be dyed in full color with a disperse dye and has high dyeing fastness, which is preferable. Moreover, since two or more different polyester fibers are used, the coloring properties of the polyester fibers are different, and the disadvantages of the glossy and deep hue peculiar to the polyester fibers can be improved.

The fabric constituting the breast cup is not particularly limited, and a conventionally known fiber sheet such as a woven fabric, a knitted fabric, or a non-woven fabric is used. In particular, in order to obtain good shape retention of the breast cup material, a bulky multiple structure is preferably applied to both woven fabric and knitted fabric. As a specific example, in textiles,
Vertical double woven fabric, horizontal double woven fabric, vertical horizontal double woven fabric, etc.
For knitted fabrics, jersey fabrics, particularly double jersey fabrics, double Russell fabrics, moquette fabrics or cardboard knit fabrics are preferably applied. Here, the corrugated cardboard knit refers to a multi-layered knitted or three-dimensional knitted fabric in which a surface material and a lining are connected by a middle yarn (called a connecting yarn, a joint yarn or a connecting yarn).

The clothing having the breast cup of the present invention includes a bra, a body suit, and the like having the breast cup.
Bustier, Blatdy, Three in One, Bra Camisole, Bra Slip, Long Line Bra, Swimsuit (Figure 2
(See Fig. 11)
It is possible to provide clothing that is elegant and functional with good shape retention and is difficult to obtain with conventional techniques.

Next, a preferred method of manufacturing a garment having the breast cup of the present invention will be described below.

The polyester fiber has a birefringence Δn of 0.02 to 0.08. Preferably, Δn is 0.03-0.
A highly-oriented undrawn yarn of No. 06 and a drawn yarn of a polyethylene terephthalate ultrafine fiber filament having a single yarn fineness of 2 dtex or less are knitted into a multi-knitted fabric to produce a greige machine.

Here, the birefringence index Δn is a value measured by the Cernamon method and the compensator method using D-line color light with a Na bulb.

Then, the greige is heat-treated in a dry and / or wet atmosphere at 60 to 95 ° C., and is gently heated to 2% / sec or less, preferably 1% / sec or less, particularly preferably 0.5% / sec. 10-25% for both shrunk length and width
Shrink. As described above, it is preferable to limit the contraction so that the fiber sheet contracts while receiving the resistance. Sudden exposure to a high-temperature atmosphere or sudden shrinkage is not preferable for the characteristics of a breast cup, a smooth surface, and a flexible fiber sheet. These special processing conditions enable deep drawing with little thickness unevenness in the subsequent molding step, and are important for producing the breast cup of the present invention. This point is also completely different from the prior art.

Then, using a dyeing machine, in a disperse dye bath at a temperature of at least 55 ° C. to 70 ° C., 0.5 ° C./min or less, preferably 0.3 ° C./min or less, particularly preferably 0.2 ° C./min. / Minute at a very slow rate.
To make a fiber sheet for producing the breast cup of the present invention,
These conditions for raising the temperature of dyeing are important and are the requirements for expressing the unique characteristics of the present invention. In other words, this condition is also one of the requirements for enabling deep drawing with less thickness unevenness in the subsequent forming step. Further, in this dyeing, at least at room temperature to 50 ° C, 0.3 ° C / min or more, preferably at least 0.3 ° C / min.
Temperature is raised at a rate of 5 ° C./or more, at least 55 ° C. to 70 ° C.
0.5 ° C./min or less, preferably 0.3 ° C./min or less,
Particularly preferably, the temperature is raised at an extremely slow rate of 0.2 ° C./min or less,
A method of increasing the temperature at a rate of at least 0.5 ° C./min, preferably at least 0.5 ° C./min is preferably applied. When the heating is completed,
Stain at 130 ° C. for 10-60 minutes. Of course, conventionally known reduction washing may be performed to remove excess dye, if necessary.

Further, a functional agent such as an antistatic agent, a softening agent and an antibacterial agent may be provided to give a conventionally known finishing set.

The obtained processed fiber sheet is set in a breast cup-shaped mold and pressed at 130 to 230 ° C. with a clearance of 0 to 3.0 mm for 10 to 180 seconds.
It is made by cutting it into a cup shape and sewing it using a member suitable for clothing.

Of course, the breast cup of the present invention may be used as a core material, and a lace may be provided on the surface, or a decoration or pattern may be provided by printing.
