JP2002155403A - Cup for brassiere - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide cups for a brassiere, which are soft and excellent in air permeability when worn, capable of always keeping both of the wearer's breasts stay at the desirable positions, and moreover allowing a wearer to flexibly move. SOLUTION: These cups for a brassiere have the following structure: urethane foams 2 and 6 are layered on the inside and outside of a fabric 3 stretchable or deformable by outer stress while the fabric 3 is used as a padding, wherein a thermoforming resin liquid is sprayed on the lower or side part of the fabric 3 to subject the part to thermoforming to make inextensible portion 8.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brassiere cup used for a breast part of a women's bra, and more particularly to a brassiere cup which is formed by thermoforming and has a telescopic part and a non-telescopic part. It is.

[0002]

2. Description of the Related Art A conventional brassiere cup of this type is mainly made of a non-stretch type made by thermoforming a thick polyester nonwoven fabric and a thermoformed mainly urethane foam. Elastic type is common. Some sewing types connect a non-stretchable fabric and a stretchable fabric (see, for example, JP-A-11-1).
No. 2807).

[0003]

Among the things described in the prior art, the non-stretch type has no escape of the breast when worn,
There is a problem in wearing feeling and fitting property.

[0004] In addition, the stretchable type has a problem in that it is difficult to maintain a desired position of the breast when worn, since the stretchability extends over all parts.

[0005] In addition, the sewing type has a problem that it takes time and labor to perform three-dimensional molding, and the finished product lacks beauty.

SUMMARY OF THE INVENTION The present invention has been made to solve such problems of the prior art, and it is an object of the present invention to provide a soft and comfortable feel not worn on both the outside and inside, when worn. An object of the present invention is to provide a bra cup for producing a bra that has both good feel and a beautiful shape, always holds both breasts in a desirable beautiful position, and has good operability.

[0007]

In order to achieve the above-mentioned object, a brassiere cup according to the present invention has a cloth 3 (hereinafter referred to as cloth) which can be expanded or contracted or deformed by an external stress, and has a core inside and outside. In the structure in which the urethane foams 2 and 6 are laminated, a thermosetting resin liquid is sprayed on the portion 5 of the fabric 3 located at the portion 8 of the brassiere cup main body 1 below or to the side of the non-stretchable target, and then the urethane foam. An adhesive is sprayed on a contact surface between the fabrics 2 and 6 and the fabric 3 and thermoformed to form an upper elastic portion 7 and a non-elastic portion 8 whose extension is stopped by a lower or lateral resin.

The arrangement of the non-stretchable portions 8 and the stretchable portions 7
The stretching force and the amount of stretching can be arbitrarily set by selecting the stretching characteristics of the fabric 3 according to the type of the bra and the covering material of the bra.

The fabric 3 may be a woven fabric, a knitted fabric, a braided fabric, a nonwoven fabric, or the like. However, when a thermosetting resin liquid is sprayed and heated, the entangled portions of these fiber aggregates are fixed and the fabric is stretched. You need to choose one that converts to non-stretch. In addition, a woven fabric that expands and contracts in the bias direction is also included. Fabric 3
With respect to the composition, thermoplastic materials such as polyester and nylon which are easily thermoformed are desirable.

For the convenience of the manufacturing process, only the fabric 3 to which the thermosetting resin liquid has been sprayed may be thermoformed in advance and bonded to the urethane foam in a separate process.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. 1, 2, and 3, FIG. 1 is a front view of a brassiere cup having a non-stretchable portion on the lower side and a partially exploded view, and FIG. 2 is a cross-sectional view thereof. FIG. 3 is a front view of the brassiere cup on the left side having a non-stretchable portion from the lower side to the side. The inner urethane foam 2 has a thickness of 1.5 mm, the outer urethane foam has a thickness of 3.0 mm, and the fabric 3 is a polyester needle-punched nonwoven fabric having an elongation of about 30% and a basis weight of about 70 g / m ² . In a step before bonding each of them by thermoforming, a thermosetting resin liquid is sprayed on the lower or side portions 5 of the fabric 3 and an adhesive is sprayed on each bonding surface of the inner and outer urethane foams 2 and 6. Then, the resin is hardened by the heat at the portion of the resin non-spreading portion 4 of the fabric 3 at the stretchable portion 7 and at the portion of the resin spraying portion 5 of the fabric 3 by the thermoforming for several minutes with the fabric 3 as the core. Only the entangled portions of the fibers of the fabric 3 are fixed and bonded to the inner urethane foam 2 and the outer urethane foam 6 at the non-stretchable portion 8 having air permeability.

Although not directly related to the practice of the present invention, a flat knitted fabric or a tricot knitted fabric using stretchable polyester processing yarn may be attached to the outside and inside of the cup as necessary. Can be commercialized.

[0013]

Since the present invention is configured as described above, the following effects can be obtained.

[0014] In the bra cup according to the first aspect,
Since the lower and side parts are configured to be non-stretchable and the upper part is configured to be stretchable, it is ensured that the breast is held at the lower and side non-stretchable parts when the brassier is finished and worn. It prevents sagging or escaping to the side, so that both breasts can always be kept in the desired beautiful position.

Further, the upper elastic portion is excellent in operability since the elasticity of the fabric and the elasticity of the urethane foam are involved.

[0016] The coarser fabric is enclosed in the inner layer, and the soft urethane foam faces the skin side and the outside, so that a good feeling can be obtained.

Further, since the adhesion between the fibers of the fabric and the adhesion to the urethane foam are all partial adhesions, the air permeability is maintained.
