2. Description of the Related Art Conventionally, girdles, body suits, body shapers, waist nippers, etc. have been widely used as underwear for manipulating the body of a wearer.
Of these, for girdles and bodysuits,
For example, as shown in FIGS. 5 and 6, a strong net cloth using a thick wire such as nylon or polyurethane for adjusting the body shapes of the lower abdomen (A), waist (I) and buttocks (U). It is known that a mold is molded using a mold, and this is sewn to a predetermined part of a piece of underwear to have a manipulative function. In addition, as shown in FIG. 7, the body shaper is provided with a manipulative function in the same manner as the girdle or bodysuit as described above for body shape correction of the lower abdomen (a) and waist (a). There is something.
Further, as for the waist nipper, as shown in FIG. 8, normally 6 to 8 metallic reinforcing members called bones (d) are vertically attached to adjust the body shape of the waist portion (a). .

[0003]

However, for example, in the case of the girdle, body suit and body shaper shown in FIGS. 5 to 7, the strength of the dough is used to hold down a part of the body. Therefore, as long as fibers such as nylon and polyurethane are used, the tensile strength is strong, but the strength is weak and insufficient to retain the three-dimensional shape of the fabric itself, and it is difficult to adjust to a beautiful figure. There is a drawback.

Further, in the case of the waist nipper as illustrated in FIG. 8, the waist portion (a) is clamped in the circumferential direction by utilizing the tensile strength of the cloth, and is restrained by the bone (d). There was a problem that it lacked the manipulative function to prepare a beautiful three-dimensional figure. The present invention has been made in view of the circumstances as described above, and it is possible to eliminate the drawbacks of the conventional underwear for manipulative treatment, improve the comfort, and also improve the manipulative treatment function for adjusting the wearer's body shape. , An object is to provide a new underwear for manipulative treatment using a shape memory alloy.

[0005]

Means for Solving the Problems The present invention is to solve the above problems by subjecting a woven or knitted NiTi-based shape memory alloy wire to a shape of a part of underwear by shape memory heat treatment,
Provided is an underwear for manipulative treatment, which is characterized in that a transformation temperature is adjusted so that an austenite phase appears at a temperature at the time of wearing and is attached to the underwear to hold a part of the shape of the underwear.

Further, according to the present invention, when a net-like or cloth-like woven or knitted material is made of NiTi-based shape memory alloy wire, a metal wire of stainless steel, titanium, tan alloy, or amorphous alloy, or a melting point of 250 ° C. or more. It also includes a combination of one or more types of synthetic fiber yarns such as polyester, acrylic and nylon. Thus, a woven or knitted fabric produced by NiTi-based shape memory alloy wire alone or in combination with other metal wires or yarns of synthetic fiber is used in a part of the shape of underwear, that is, in the case of girdle and body suit, for example. Is a lower abdomen (1), a waist (2) and a buttocks (3) as illustrated in FIGS. 1 and 2, and in the case of a body shaper, a lower abdomen is illustrated as illustrated in FIG. (1) and waist (2),
Further, in the case of a waist nipper, as illustrated in FIG. 4, shape memory heat treatment is performed to a shape corresponding to each of the waist portion (2) and the portion (4) corresponding to the bone of the conventional waist nipper, Adjust the transformation temperature so that the austenite phase appears at the temperature of wearing, and attach it to underwear.

The austenite phase of the NiTi alloy is in a superelastic state, has a low elastic modulus as compared with other metal wire rods such as steel, and has a wide range of deformation that maintains elasticity and is supple. ing. This NiTi-based alloy wire is heat-treated in advance so that the shape of the body is memorized so as to correspond to the shape of a part of the body shaping underwear as described above, and the wearer's body shape can be beautifully adjusted without losing the shape, The wearing comfort can be improved. In particular, in the case of the waist nipper illustrated in FIG. 4, the hard reinforcing member made of metal, which is conventionally attached, such as a hard bone, is unnecessary, and the waist portion (2) does not have a feeling of pressure. Also, the line of the waist part (2) becomes clean.

[0008]

In the manipulative undergarment of the present invention, the net-like or cloth-like woven or knitted material of NiTi-based shape memory alloy is used as a part of the manipulative undergarment to maintain the three-dimensional shape and strength, and While taking advantage of the suppleness, it is possible to eliminate the discomfort at the time of wearing and smoothly adjust the wearer's body shape.
