Problems to be solved by the invention

[0004] However, in the garment described in Patent Document 1, the degree of elongation of the greaves imparted to the fabric (hereinafter referred to as "greaves") has not been sufficiently studied. That is, when the garment described in Patent Document 1 is stretched and contracted by closely contacting the fat portion with the body, it is insufficient to cause the fat portion to follow the movement of the body and sufficient tightening force cannot be obtained. There is. Therefore, in the garment described in Patent Document 1, there is still room for improvement in the binding force and power of the grease part.

[0005] Also, in the garment described in Patent Document 1 above, the air permeability before and after the application of rosin has not been fully studied, and if the air permeability is insufficient, particularly in bottom clothing. , The feeling of wearing may be inferior due to the skin becoming wet.

[0006] Therefore, the present invention provides a stretchable fabric, clothing, clothing, a method for producing the stretchable fabric, and a method for producing the clothing that can achieve sufficient body restraining force and power and realize an excellent wearing feeling. It aims to provide a method.

(1) The clothing shall have a tightening part, and the tightening part shall have a tightening force (no body restraint or power) that can correct the posture of the wearer.

(2) Since clothing stretches and contracts in close contact with the body, it has sufficient elongation to follow its movement, and tightening force is not lost even after repeated stretching.

(3) Since clothing is used in close contact with the body, the fabric has good air permeability and the air permeability of the tightening portion is not lost.

[0008] That is, the present invention is a stretchable fabric having a tightening portion on at least a part of the fabric, wherein the tightening portion has a resin portion made of elastic resin, and the fabric is pulled in the warp direction. Provided is a stretchable fabric having an elongation of 100 to 200% and an elastic resin having a breaking elongation of 500% or more and a 200% modulus of 5NZmm ² or less.

[0009] Here, the tightening portion refers to a portion that can be stimulated by directly applying a load to the body. The tensile elongation in the warp direction of the fabric means the elongation at the load assumed at the time of wearing, and in this specification, it was measured by applying a load of 22.1 N to a sample with a width of 2.5 cm. It is indicated by the elongation (%). The warp direction of the fabric refers to the knitting direction of the fabric. The elongation at break refers to the elongation at break when a load is applied to the resin film, and represents the ease and strength of the resin. 200% modulus refers to the resin stress when stretched by 200% and represents the softness of the resin.

[0010] When the elastic fabric is used as a garment, the tightening portion is provided in a portion that is in close contact with the wearer's body. Can follow and directly stimulate the wearer's body (especially muscles). In addition, by arranging the above-mentioned elastic resin portion in a proper position in the fabric structure, the tightening portion provided with the above-described resin portion and the fabric has sufficient air permeability and exhibits sufficient tightening force. be able to.

[0012] Further, the tensile elongation in the warp direction of the stretchable fabric and the elongation at break of the resin portion are determined. By setting the amount within the above range, in the garment using the stretchable fabric, the tightening portion can reliably follow the movement of the garment body and can maintain the stretchability even after repeated stretches. Therefore, according to the stretchable fabric of the present invention, it is possible to correct or shape the wearer's body shape, correct the posture, and improve the motor functionality.

[0013] In the stretchable fabric of the present invention, the thickness of the greave portion is preferably 75 μm or less, more preferably 30 m or less. In the present invention, the thickness of the greave portion refers to a value expressed by a value obtained by dividing the thickness of the fabric having the greave portion. FIG. 3 is a cross-sectional view schematically showing an example of the stretchable fabric of the present invention. The stretchable fabric 10 shown in FIG. 3 is configured to include a fabric 12 and a greave portion 15, and a part of the greave portion 15, that is, a part of the cocoon liquor penetrates into the fabric 12. Yes. For example, in such a stretchable material 10, the thickness of the resin portion means a.

[0014] By setting the thickness of the oil-repellent portion to 75 μm or less, it is possible to reduce unevenness and oiliness in the tactile sensation and improve slipperiness.

Is preferably provided with the above-mentioned rosin portion so that it is within 30%. Here, the degree of penetration of the elastic resin into the fabric is determined from the thickness of the hydrophilic resin that has penetrated into the fabric based on a cross-sectional photograph of the stretch fabric cut in the thickness direction. For example, in the stretchable fabric 10 shown in FIG. 3, the thickness of the cocoon resin penetrating the fabric is b, and the thickness of the fabric is c. In this case, the penetrability of the cocoa butter into the dough is a value obtained by the formula [penetration (%) = bZc X 100].

[0016] In the stretchable fabric of the present invention, from the viewpoint of sufficiently maintaining the tightness and followability of the tightening portion and sufficiently maintaining the air permeability of the fabric, the yarn of the fabric is not completely filled between the fabric structures. It is preferable that the said grease part is provided so that an entanglement part may be restrained.

[0017] The stretchable fabric of the present invention preferably has a partial force of 0.5 ml / cm ² 's or more having a greave portion in the tightened portion. Here, the air permeability is measured by JIS L 1096 (7-radial method) and refers to the degree to which the gas phase inside and outside the clothes can travel through the fabric. In addition, the higher the air permeability value, the more effective the suppression of stuffiness. [0018] In the stretchable fabric of the present invention, from the viewpoint of more surely exerting sufficient body restraining force, the portion having the rib portion of the tightening portion has a tightening force four times or more that of the fabric. It is preferable that Here, the tension force means the stress at the time of contraction in expansion and contraction, and in the present invention, the value at the time of 10% extension is!

[0019] In the stretchable fabric of the present invention, from the viewpoint of more surely exerting sufficient body restraint force, the portion having the oil-absorbing portion of the tightening portion has a stretch force that is four times or more that of the fabric. It is preferable that Here, the term “extension force” refers to the stress at the time of extension in expansion and contraction, and in the present invention, the value at the time of 10% extension!

[0020] In the stretchable fabric of the present invention, from the viewpoint of suppressing a decrease in body restraining force when repeatedly worn, the hysteresis of the portion having the bulge portion of the tightening portion may be 0 to 80 cN. preferable. Here, the hysteresis means a difference between the extension force and the tension force. In the present invention, hysteresis is a value obtained from the equation [hysteresis = 10% stretching force-10% tension]. A hysteresis close to 0 provides a stable body restraint and an excellent wearing feeling.

[0021] Further, in the stretchable fabric of the present invention, the thickness of the rosin portion is 75 μm or less, the penetration of the elastic greaves into the fabric is within 50% based on the thickness of the fabric, and the fabric It is preferable that a greave portion is provided so as to constrain the yarn entanglement portion of the fabric without completely filling the space between the two. In this case, the effect of the present invention can be further achieved. That is, the tightening portion comprising the above-described elastic resin, the thickness on the fabric and the degree of penetration within the above-mentioned ranges, and being arranged at appropriate positions in the fabric structure, the tightening portion including the strong grease and fabric is provided. In addition to having sufficient ventilation, it is possible to ensure that sufficient tightening force is exhibited.

[0022] Further, in the stretchable fabric of the present invention, the partial force having the greave portion of the tightening portion is 0.

It is preferable that it has a breathability of 5 mlZcm ² 's or more, has a tension force of 4 times or more to the fabric, and has a hysteresis of 0 to 80 cN. In this case, the effect of the present invention can be further exhibited. That is, according to the stretchable fabric that is strong, the body restraint force, the long-term stability of the body restraint force, and the feeling of wearing can be maintained at a high level and in a well-balanced manner.

[0023] In the stretchable fabric of the present invention, the fabric is preferably a knitted fabric containing polyurethane elastic yarn. In this case, the garment can follow the movement of the wearer's body. In addition, even when the expansion and contraction is repeated, the stretchability can be further maintained.

[0024] In the stretchable fabric of the present invention, it is preferable that the oil-absorbing portion is formed by arranging oil-absorbing dots two-dimensionally. The tightening portion having the above-mentioned grease portion can weaken the tightening force as compared with the case where the entire surface of the tightening portion is a grease portion. For example, when a tightening part is provided in a part where the body movement of the wearer is large, the body is difficult to move while exerting a tightening force that can correct posture by weakening the tightening part of the tightening part. It is possible to suppress the occurrence of this.

[0025] In this case, the tightening portion can cause the tightening portion to follow the movement of the body regardless of the directionality.

[0026] Further, in the stretchable fabric of the present invention, it is preferable that the greave portion is formed by arranging a plurality of grease lines along a certain direction. The tightening portion having the above-mentioned grease portion can exert a tightening force particularly in the line direction. In other words, if the direction of the line is the vertical direction, the tightening force can be exhibited particularly in the vertical direction, and the tightening force can be weakened in the lateral direction. Therefore, from the viewpoint of wearing feeling, it is preferable to provide the above-described tightening portion according to the body part when it is desired to apply the tightening force only in one direction.

[0027] The present invention provides a garment made of the above-described stretchable cloth according to the present invention. The garment of the present invention is preferably a bottom garment.

[0028] Further, the present invention provides a garment in which the garment is a girdle or shorts. In this case, the tightening portion having a predetermined shape formed on the part where the lower body of the wearer is in close contact with each other can exert a tightening force on the quadriceps muscles and the like. As a result, the quadriceps muscle is stimulated and the gluteal muscle is used. Therefore, by wearing the girdle or shorts, a beauty and a hip line can be easily formed.

[0029] The method for producing a stretchable fabric of the present invention has a tensile elongation in the warp direction of 100 to 200%, a predetermined elongation on a surface of the fabric, a breaking elongation of 500% or more, and a 200% modulus. the榭脂portion made of an elastic榭脂is force NZmm ² or less, thickness after printing is below 75 mu m, penetration of the elastic榭脂to the thickness of the fabric is within 50%, and the elastic榭脂live It is characterized in that it is formed by screen printing or rotary printing so as to constrain the yarn entanglement portion without completely filling the ground structure. [0030] By using screen printing or rotary printing as a method for imparting greaves to the fabric, the shape and thickness of the greave portion can be adjusted. In addition, the method for producing a stretchable fabric of the present invention is excellent in productivity because mass production is possible by providing the above-mentioned shape on a screen printing plate or a rotary printing plate.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings as necessary. In the drawings, the same elements are denoted by the same reference numerals, and duplicate descriptions are omitted. Further, the dimensional ratios in the drawings are not limited to the illustrated ratios.

FIG. 1 is a view showing a girdle which is an embodiment of the present invention. Fig. 1 (a) shows the front side of the girdle, and Fig. 1 (b) shows the rear side of the girdle. The girdle 1 shown in Fig. 1 is a bottom garment for hip tray jung. The girdle 1 is provided on the main body 2 and a part of the main body 2 Consists of tightening portions 3a, 3b and 3c. In the following, the tightening portion 3a, the tightening portion 3b, the tightening portion 3c, and the tightening portion 3d are referred to as the tightening portion 3 when it is not necessary to distinguish between them.

[0037] In Figs. 1 (a) and (b), the tightening portion 3 is formed at a position where the girdle 1 is in close contact with the wearer's body. In other words, the tightening portion 3a is formed in a band shape at the upper end of the waist of the girdle 1, and the ends are separated from each other on the front side of the upper end of the waist. The tightening portion 3b is formed in the form of a belt on the front side of the thigh and the thigh inner force is directed toward the outer side of the thigh, and intersects each other in the vicinity of the center of the thigh. A tightening portion 3c is formed at the intersecting portion. The tightening portion 3d extends from the rupture side to both sides along the ridge groove portion. Further, the tightening portion 3c has a tapered shape as the cracking portion force is separated.

[0038] When the girdle 1 of the present embodiment is worn, the tightening portion 3a comes into contact with the iliac crest of the human body, so that it is possible to apply a tightening force to this portion. As a result, the girdle 1 can be prevented from sliding down and the waist can be tightened.

[0039] In addition, the tightening portion 3c exhibits a tightening force stronger than that of the tightening portion 3b, and is in contact with a portion corresponding to an intermediate point between the intestinal spine point of the human body and the center point of the patella. It is possible to exert a strong tightening force against the quadriceps. This stimulates the quadriceps muscles, so when the wearer walks, the leg will naturally be kicked far behind and the greater gluteus muscle will be used. Therefore, in this case, a beautiful hip line can be easily formed.

[0040] The tightening portion 3b has a tightening force weaker than that of the tightening portion 3c, and is formed so as to intersect at the portion corresponding to the intermediate point. Therefore, the tightening portion 3b stimulates the thigh muscle. While added, it has a structure that does not hinder the work of muscles.

[0041] Since the tightening portion 3d abuts against the heel groove portion, it is possible to apply a tightening force to the greater gluteal muscle located in this portion. This makes it easy to form beauty and hip lines. In addition, the tightening part 3d has a tapered shape as it moves away from the rupture side, so that the tension of the tightening force is adjusted to prevent the feeling of wearing especially when standing or sitting it can.

[0042] Since the tightening portion 3 includes a grease portion, when the tightening portion 3 is provided on the girdle 1, The girdle 1 has a shape in which the tightening portion 3 protrudes. Therefore, in the present embodiment, the tightening portion 3 is provided on the outer side (opposite to the body) with respect to the girdle 1. Therefore, the guardle 1 can be excellent in wearing feeling.

[0043] In the present embodiment, the main body 2 is made of a fabric, and the tightening portions 3a, 3b, and 3c have a configuration in which a grease portion is provided on the fabric.

[0044] Examples of the fabric include natural fibers, rayon, polyester, nylon, and cellulosic fibers. These may be used alone or in combination. Further, these materials may be a composite of elastic yarn such as polyurethane.

[0045] Among these, the fabric is preferably made of nylon and polyurethane elastic yarn. In this case, there is a 禾 IJ point that it is easy to obtain physical properties, texture, and dyeing fastness that are suitable for clothes that are soft to the touch.

[0046] The fabric structure is preferably stretchable, such as warp knitted fabric, weft knitted fabric or stretch fabric, and the elongation is limited. Of these, warp knitted fabric is more preferred. In this case, the shape of the dough is stabilized and it is possible to suppress the unraveling. In addition, the garment in this case can follow the movement of the wearer's body and can retain more stretchability even after repeated stretching.

[0047] In addition, it is preferable to use a fabric whose power has been switched, even though it is preferable to use a stretchable material. The end part is an unnecessary material for sewing, and by changing the number and thickness of elastic yarns or changing the knitting structure, it is possible to make a difference in power strength. Furthermore, in this case, it is possible to exert a stronger power by providing the greave portion.

[0048] In the present embodiment, the tensile elongation in the warp direction of the fabric is 100 to 200%, preferably 140 to 180%. When the tensile elongation of the fabric is less than 100%, the wearer tends to be difficult to move, and when the tensile elongation of the fabric exceeds 200%, the adhesion to the body and the fit tend to decrease. The tensile elongation in the warp direction of the fabric is indicated by the elongation (%) when measured with a load of 22.1N on a sample with a width of 2.5 cm.

[0049] For the present embodiment, the rupture elongation of the above-described hydrophilic resin is preferably 500% or more, preferably Is 700-1500%. When the breaking elongation of the cocoon resin is less than 500%, when the tightened part is stretched, the cocoon part tends to be damaged and the stretching force and the tightening force tend to be impaired. On the other hand, when the elongation at break of the elastic resin exceeds 1500%, sufficient stretching force and tension force tend to be obtained.

[0050] In the present embodiment, the 200% modulus of the cocoon resin is 5 NZmm ² or less, preferably 2.5 NZmm ² or less. When 200% modulus exceeds 5NZmm ^2, together with the texture of the tightening portion is significantly harder,榭脂is separated ease no longer when the tightening portion is extended, stretch force, tends to radial load is impaired. Further, the 200% modulus of the elastic resin is preferably 0.5 NZmm ² or more.

[0051] In this embodiment, by setting the breaking elongation and the tensile elongation of the fabric in the above ranges, it is possible to follow the movement of the body and maintain the elasticity even after repeated expansion and contraction. Can. Therefore, according to the girdle 1 of the present embodiment, it is possible to correct or shape the wearer's body shape, correct the posture, and improve motor functionality.

[0052] The thickness of the rosin portion is preferably 75 µm or less, more preferably 30 µm or less. If the thickness of the cocoon part exceeds 75 m, the greaves tend to fill the space between the fabrics and the air permeability tends to decrease. In addition, when the thickness of the resin portion exceeds 75 m, a feeling of unevenness occurs, the feeling of touch and the oiliness increase, and the slipperiness tends to be poor.

[0053] The permeability of the greave portion to the dough is 50% or less, preferably 30% or less, with respect to the thickness of the dough. When the penetration of the fat is 50% or more, the texture becomes remarkably hard, and the back leakage of the fat on the skin side occurs, which tends to be difficult to wear.

[0054] The area occupied by the resin portion in the tightening portion is preferably 30% or more. When the area occupied by the resin part is less than 30%, the tightening force tends to be insufficient as compared with the case where the area occupied by the resin part is in the above range. Note that the tightening force increases as the percentage of effort increases.

[0055] Silicone, urethane, acrylic, or nylon resin is used for the hydrophilic resin constituting the resin part, but is not particularly limited. In this way, the fat portion is composed of the elastic resin, and by setting the thickness of the strong fat portion to be in the above range, the tightening portion can be tightened to a degree that can correct posture (body restraining force). (And power) wear.

[0056] When the elastic resin constituting the resin part is urethane, it can be excellent in adhesion to the fabric, flexibility and strength. The polyurethane preferably has an ether bond or a carbonate bond in the molecule. In this case, the resin itself can be prevented from being discolored or deteriorated.

[0057] In the present embodiment, the tightening portion 3 includes the fabric and the grease portion. Of frettage clamping unit 3, and more preferably portion breathable with榭脂portion is 0. 5mlZcm ² 'Sig 2MlZcm ² is preferred that s or greater' s or more. When the air permeability is 0.5 mlZcm ² s or more, it is possible to suppress the occurrence of a situation such as swelling of the skin when worn, and the wear feeling is excellent. In the tightening portion 3, the “portion having the grease portion” means a portion where the fabric is covered with the grease portion, and the values of the air permeability and the stretching force are the same for the fabric. It is a value obtained by measuring the covered part.

Here, the tightening force (body restraining force or power) will be described. The strength of the tightening force can be expressed by the tightening force and the stretching force.

[0059] In the present invention, it is preferable that the tightening force of the tightened portion having the oil-filled portion is 100 to 150 cN. Here, the tension force means the stress at the time of contraction in expansion and contraction, and in the present invention, it means the value at the time of 10% extension. When the tightening force is less than lOOcN, the body restraining force tends to decrease compared to the case where the tightening force is in the above range, and there is a tendency that the originally required function does not exist. When the tightening force exceeds 150 cN, Compared to the case where the tightening force is in the above range, the body restraint force is too strong, and it tends to be compressed when worn and inferior in wearing feeling.

[0060] Further, it is preferable that the tension force is four times or more than the tension force of the fabric. Further, the tension force is preferably 10 times or less than the tension force of the fabric. If the tightening force of the tightening part is less than 4 times the tightening force of the fabric, the body restraining force will be reduced compared to the above range, which is essential. There is a tendency to have no function. On the other hand, if the tightening force of the tightened part that has the oil-absorbing part exceeds 10 times that of the fabric, the body restraint force is too strong compared to the range described above, and it is compressed when worn. It tends to be inferior in wearing feeling.

[0061] It is preferable that the extension force of the portion having the grease portion in the tightening portion is 150 to 200 cN . Here, the term “extension force” refers to the stress at the time of expansion / contraction, and in the present invention, the value at the time of 10% expansion. When the stretching force is less than 150 cN, the body restraining force tends to be lower than when the stretching force is in the above range. When the stretching force exceeds 200 cN, the stretching force is within the above range. In addition, the body restraint force is too strong, and it tends to be inferior in wearing feeling because it is pressed when worn.

[0062] Further, it is preferable that the stretch force of the portion having the grease in the tightening portion is four times or more than the stretch force of the fabric. In addition, it is preferable that the stretching force of the portion having the grease in the tightening portion is not more than 10 times the stretch tension of the fabric. If the stretch tension of the tightened part is less than 4 times the stretch force of the fabric, the body restraining force will be reduced compared to the above range, which is essential There is a tendency to have no function. On the other hand, if the tensile force of the part of the tightening part that has the grease part exceeds 10 times the tensile force of the fabric, the body restraining force is too strong compared to the above range, and “Inclined I mouth that is pressed and inferior in wear”.

[0063] It is preferred that the hysteresis of the portion having the grease portion in the tightening portion is 0 to 80 cN.

Here, hysteresis refers to the difference between the stretching force and the tension force. In particular,

Hysteresis = 10% extension force 10% tension

Is required. If the hysteresis exceeds 80 cN, compared to the case where the hysteresis is in the above range, it is difficult to obtain a stable body restraint at the time of wearing, and there is a tendency for the wearing feeling to be lowered.

[0064] When the tightening force, the stretching force, the hysteresis force, and the deviation are within the above ranges, the tightening portion can more reliably exert a sufficient tightening force.

[0065] Here, the shape of the grease portion 5 in the tightening portion 3 will be described with reference to FIG. The shape of the resin portion 5 in the tightening portion is not particularly limited, but for example, the shape shown in FIGS. 2 (a) to (f) is preferable.

[0066] In the tightening portion shown in Fig. 2 (a) (hereinafter referred to as "first tightening portion" for convenience), all of the fabric is covered with the grease portion. However, the greaves do not completely fill the space between the fabrics. The first tightening portion having a strong shape can exhibit a particularly strong tightening force. Note that the shape force of the tightening portion 3c of the girdle 1 shown in FIG. 1 corresponds to the shape of the first tightening portion. [0067] The tightening portion shown in Fig. 2 (b) (hereinafter referred to as "second tightening portion" for convenience), and the tightening portion shown in Fig. 2 (c) (hereinafter referred to as "third tightening portion" for convenience). 2) and the tightening portion shown in FIG. 2 (d) (hereinafter referred to as “fourth tightening portion” for the sake of convenience) are formed by providing the grease portions 5 on the fabric in a lattice shape. Yes. Here, in the second tightening portion, the adjacent lattice interval is the narrowest compared to the third tightening portion and the fourth tightening portion, and the fourth tightening portion is the widest. Therefore, the second tightening portion can exert a tightening force stronger than the third tightening portion and the fourth tightening portion, which are weaker than the first tightening portion. It can exert a tightening force stronger than 4 tightening parts. The shape of the tightening portion 3c of the girdle 1 shown in FIG. 1 corresponds to the shape of the second tightening portion, and the shape force of the tightening portion 3d of the girdle 1 shown in FIG. 1 becomes the shape of the third tightening portion. Corresponding to the shape force of the tightening portion 3a of the girdle 1 shown in FIG. 1, this corresponds to the shape of the fourth tightening portion.

[0068] The grease part 5 in the fastening part shown in FIG. 2 (e) (hereinafter referred to as "fifth fastening part" for convenience) has a two-dimensional form of the grease dots made of the above-mentioned elastic grease on the fabric. It is arranged and arranged. In this case, the fifth tightening portion can be weaker than the first to fourth tightening portions. Therefore, for example, when the tightening portion is provided in a portion where the body movement of the wearer is large, it is possible to suppress a situation in which the body is difficult to move by weakening the tightening force of the tightening portion.

[0069] The first to fifth tightening portions can be made to follow the body movement regardless of the directionality.

[0070] The tightening portion shown in Fig. 2 (f) (hereinafter referred to as "sixth tightening portion" for convenience) and the tightening portion shown in Fig. 2 (g) (hereinafter referred to as "seventh tightening portion" for convenience). )), The resin part 5 is configured by arranging a plurality of resin lines made of the elastic resin on the fabric along a certain direction. In this case, the tightening portion can exert a tightening force particularly in the direction of the grease line. That is, when the direction of the resin line is the vertical direction, the tightening force can be exhibited particularly in the vertical direction, and the tightening force can be weakened in the lateral direction. Therefore, especially when it is desired to apply tightening force in one direction, such as a feeling of wearing, tightening portions can be provided according to the body part. In addition, in the sixth tightening portion, the interval between the adjacent grease lines is narrower than that in the seventh tightening portion. Therefore, the 6th tightening part is more than the 7th tightening part. Strong tightening force can be demonstrated. Note that the sixth and seventh tightening portions can cause the tightening portion to follow the movement of the body.

[0071] As shown in Figs. 2 (a) to (d), (f), and (g), it is preferable that the greaves are continuous. The tightening portion in this case can exert not only the pressing force but also the tightening force in the fabric direction on the contraction of the muscle.

[0072] In this way, the tightening portion can change the direction in which the tightening force acts depending on the position and shape of the provided grease portion. Therefore, a desired tightening portion can be used in accordance with the movement of the muscles and the feeling of wearing. By using an elastic fabric having such a tightening portion, sufficient body restraining force and power can be obtained, and a garment having a good wearing feeling can be provided.

[0073] Next, a method for producing the stretchable fabric of the present invention, and a method for producing clothes and clothing will be described.

In the method for producing a stretchable fabric of the present embodiment, first, a fabric is prepared. The raw material should have a tensile elongation in the warp direction of 100 to 200%. Here, the tensile elongation in the warp direction of the fabric refers to the value indicated by the elongation (%) when a load of 22.1 N is applied to a 2.5 cm wide sample. Then, at a predetermined position on one surface of the fabric, elongation at break strength 100% or more, and 200% modulus of elasticity榭脂form available-for榭脂solution is 5NZmm ² or less, on the fabric 75 m More preferably, it is applied so that it remains in a thickness of 30 m or less, has a penetrability of 50% or less with respect to the thickness of the base material, and constrains the yarn entangled portion without completely filling the structure. As the above-mentioned resin solution, a component that forms an elastic resin, for example, a resin in which a resin, a crosslinking agent, a catalyst, and the like as a main ingredient are dispersed or dissolved in water or a solvent is used. As the resin, it is particularly preferable to use an aqueous dispersion type resin. In this case, the work can be performed safely and the working environment is excellent. After applying the grease solution, dry at high temperature. Specifically, it is preferable to dry at a high temperature of 150 ° C or higher. In this case, the film property of the cocoa resin is improved and the adhesion can be further improved. In addition, the rosin liquid may contain a thickener as appropriate in order to adjust the thickness of the greave portion and the degree of penetration of the elastic greaves into the dough.

[0075] The method of applying the above-mentioned rosin liquid includes spraying, transfer, gravure printing, screen printing. Forces such as dyeing and rotary printing It is preferable to print by screen printing or rotary printing. Spray tends to make it difficult to apply evenly, and transfer tends to deteriorate the breathability of clothing.

[0076] By using screen printing or rotary printing as the method of applying the rosin liquid to the dough, the shape and thickness of the rosin portion can be easily adjusted. That is, in screen printing or rotary printing, it is possible to form a resin portion having a pattern such as a surface, a line, and a dot by providing a predetermined shape on the screen printing plate or the rotary printing plate to be used. Furthermore, since it can be applied continuously, mass production is possible and the productivity is excellent. Therefore, the garment in which the tightening portion is formed by screen printing or rotary printing can obtain a sufficient body restraint force and power, and has an excellent wearing feeling.

[0077] In the method for producing a stretchable fabric of this embodiment, the elongation at break is 500% or more at a predetermined position on one surface of the fabric having a tensile elongation in the warp direction of 100 to 200%, and 200 % Of modulus of 5 NZmm ² or less, and the thickness after printing is 75 m or less, and the penetration into the fabric is within 50% based on the thickness of the fabric. It is preferable to form by screen printing or rotary printing so that the resin does not completely fill the space between the fabrics and binds the yarn entangled portions.

[0078] A garment can be produced by sewing the fabric provided with the tightening portion so that the grease portion of the tightening portion is on the outside (opposite side to the body). When the garment described above is a garment with crotch, it is preferable to use a highly stretchable material for the crotch portion of the crotch garment. This is because when the garment is worn while walking in this embodiment, the stride increases, so that the operation of increasing the stride is not hindered.

[0079] While preferred embodiments of the present invention have been described above, the present invention is not necessarily limited to these.

[0080] For example, as described in the above embodiment using a girdle, the garment of the present invention is preferably a bottom garment. In addition to girdle, as bottom clothing, bra, girdle, shorts, spats, men's spats, swimwear, tights, supporters, stockings, sports tights, leotards, body suits, men's pants Applicable to clothing such as waist nippers.

[0081] Further, in the above embodiment, the shape of the tightening portion is not limited to a belt shape, and may be any shape as long as sufficient body restraining force and power can be obtained. Examples of the shape of the tightening portion include a band shape, a rhombus shape, and an oval shape.

[0082] Further, in the above embodiment, the grease dots of the tightening portion shown in FIG. 2 (e) may be a square force circle or an ellipse.
