Abstract

When (LC) is defined as compression characteristic linearity and (RC) is defined as compression resilience, a pad material (14) is configured from a urethane material satisfying (LC) ≤ 1 and (RC) ≥ 80. With a garment (1) having cup sections in which pads (11) configured from said pad material (14) are disposed at least in the lower cup sections, compression exerted on the lower sections of the bust by the lower cup sections is limited, making it possible to effectively reduce the total amount of compression exerted on the bust. Pliability, feeling of lightweightness, and feeling of fluffiness of the cup sections (2) are also increased, making it possible to have both bust shape-ability and wearing comfort.

Description

Pad material, cup material, and clothing with cup

The present invention relates to a pad material, a cup part material, and a garment with a cup part.

A garment with a cup part represented by a brassiere is, for example, a cup part for covering a bust, a base part supporting the lower edge part of the cup part, a back part extending from the base part to the back side, and a strap connected to the cup part It is configured with parts. One of the main functions of such a garment with a cup part is bust molding. For example, in the brassiere described in Patent Document 1, a cup portion is formed by a cup body and a cover that covers the surface of the cup body, and thick fabric pieces are stitched together by vertical seams to form a cup shape, The lower edge is sewn to the lower edge of the cup body.

On the other hand, there is a very high need for the comfort of clothing with cups. As a result of an investigation of brassieres frequently used by 500 applicants between the ages of 16 and 64, the percentage of consumers who answered that the emphasis is on comfort is close to 60%. Is obtained. Many consumers answered that they place importance on items related to comfort, such as fit to the body and comfort, and it can be seen that not only the formability of the bust but also the comfort is emphasized.

FIG. 10 is a diagram showing the relationship between the strength of the existing product of the clothing with a cup part and the formability. In the figure, the horizontal axis represents the strength of the wearing feeling and the vertical axis represents the formability (cup pressure), and the relationship between the wearing feeling strength and the formability of the existing products A to I is plotted. As shown in FIG. 10, in the existing products A to I, the strength of the wearing feeling and the formability are generally in a proportional relationship.

It is curved to be convex downward to fit the line.

Further, a wire portion 6 is provided on the lower edge portion 2c side of the cup portion 2. The wire portion 6 is configured by, for example, enclosing a wire member serving as a core material in a bias tape. For example, metal or plastic is used as the wire member, and a soft material such as woven fabric or knitted fabric is used as the bias tape.

The base 3 is lined with a non- (hard) stretchable material such as marquisette on a surface fabric formed of a material such as a woven fabric or a knitted fabric having a stretchability (especially a stretchability in the left-right direction) such as a bear tengu. It has non- (hard) stretchability as a whole. The upper side 3 a of the base 3 is curved in a concave shape along the lower edge 2 c of the cup 2 and is sewn to the lower edge 2 c of the cup 2. The lower side 3b of the base 3 may be provided with a terminal portion made of a material having particularly high elasticity in the longitudinal direction for the purpose of enhancing elasticity and restoration. Examples of the material used for the starting and closing parts include a stretch tape.

The back portion 4 is made of a stretchable material such as a power net. The base end side of the back part 4 is continuous from the side part of the base part 3 and extends in a band shape toward the back side. A hook 7 is provided at the back end of the back portion 4. The hooks 7 allow the left and right back portions 4 to be engaged and disengaged from each other.

The strap portion 5 is formed, for example, by forming and sewing a fabric such as a woven fabric into a string shape. A material such as a woven fabric used for the strap portion 5 preferably has stretchability in the longitudinal direction. The strap part 5 is spanned between the cup part 2 and the back part 4, and comprises what is called a shoulder strap. One end of the strap portion 5 is connected to the upper side edge of the cup portion 2, and the other end of the strap portion 5 is connected to the upper edge portion of the back portion 4.

Next, the configuration of the cup part 2 described above will be described in more detail.

FIG. 2 is an enlarged view of a main part showing the cup part 2 from the back side. As shown in the figure, a pocket 12 for detachably mounting the pad 11 is provided on the skin side of the cup portion 2. The pocket 12 is formed, for example, by sewing a fabric having good touch such as tricot on the skin side of the cup portion 2.

The pocket 12 of this embodiment is provided corresponding to the lower side (lower cup part) of the cup part 2, the lower edge part 12 a along the upper side part 3 a of the base part 3, and the front center of the lower edge part 12 a An upper edge portion 12b extending from the end on the A side to the lower side of the upper edge portion 2a of the cup portion 2 toward the side edge portion 2b, a side side of the lower edge portion 12a, and a side side of the upper edge portion 12b And a side edge portion 12c that connects the two in a straight line. The lower edge portion 12 a is sewn to the upper side portion 3 a of the base portion 3, and the upper edge portion 12 b is sewn to a position below the upper edge portion 2 a in the cup portion 2. The side edge portion 12 c is in a non-sewn state, and the pad 11 can be attached and detached from the side side of the cup portion 2.

The pad 11 has a substantially elliptical main body 13 as shown in FIG. Both ends in the major axis direction of the main body 13 have a tapered shape (a bowl shape). The main body portion 13 is configured by wrapping an elastic core material with a thin fabric having a good touch such as a tengu or a milling cutter. The thickness of the main body 13 is appropriately designed according to the required bust formability.

The core material used for the main body 13 is formed of a pad material 14. The pad material 14 is made of, for example, a foaming urethane material. FIG. 4 is a diagram showing the compression characteristics of the pad material. As shown in the figure, the compression characteristics of the pad material are indicated by the relationship between thickness and pressure.

Here, the characteristic values of the pad material include linearity LC of compression characteristics, compression work (compression energy per 1 cm ² ) WC, and compression resilience RC. The linearity LC of the compression characteristic is a parameter indicating the ease of compression at the initial stage of compression, and the smaller the value, the easier the material is compressed at the initial stage of compression. The compression work is a parameter indicating overall compressibility, and the larger the value, the easier the compression. The compression resilience is a parameter indicating recoverability after compression, and is a material whose shape is more easily recovered as the value is larger. Other parameters, the pressure _{^{P 0 (= 0.5gf / cm 2}} ) thickness _{T 0} in the addition, the pressure _{^{P m (= 50gf / cm 2}} )
The thickness T _m of a time added the like.

The linearity LC of the compression characteristic is represented by the following formula (1).

The compression work WC is expressed by the following formula (2).

The compression resilience RC is represented by the following formula (3).

The characteristic value of the urethane material constituting the pad material 14 of the present embodiment satisfies the linearity LC ≦ 1 of the compression characteristic and the compression resilience RC ≧ 80. Further, the compression work WC ≧ 6 is satisfied. Each characteristic value of the urethane material can be measured using, for example, an automated compression tester (KESFB3-AUTO-A) manufactured by Kato Tech Co., Ltd. The air permeability of the urethane material constituting the pad material 14 is preferably 250 cm ³ / cm ² · sec or more when measured by the A method (Fragile method) based on JIS L-1096. Further, the water absorption of the urethane material constituting the pad material 14 is preferably 5 seconds or less when measured by a dropping method based on JIS L1907.

The urethane material constituting the pad material 14 of the present embodiment is obtained, for example, by reacting and curing a polyol and an isocyanate (non-yellowing isocyanate). The density (foam specific gravity) of the urethane material was 35 kg / m ³ or 45 kg / m ³ .

Subsequently, the function and effect of the pad material 14 will be described.

FIG. 5 is a diagram illustrating an example of characteristic values of the pad material according to the example and the comparative example. As shown in the figure, Examples 1 to 3 are all urethane materials satisfying LC ≦ 1, RC ≧ 80, and WC ≦ 6. Example 3 is obtained by laminating a fabric made of a knitted fabric or a woven fabric such as a tengu, a milling cutter, or a tricot on the urethane material.

The characteristic values of Example 1 are LC = 0.618, WC = 6.045 (gf / cm ² ), RC = 87.77 (%), T ₀ = 4.853 (mm), TM = 0.941. (Mm). The characteristic values of Example 2 are LC = 0.695, WC = 11.850 (gf / cm ² ), RC = 89.97 (%), T ₀ = 8.230 (mm), TM = 1.409. (Mm). The characteristic values of Example 3 are LC = 0.844, WC = 13.738 (gf / cm ² ), RC = 83.54 (%), T ₀ = 8.450 (mm), TM = 1.943. (Mm).

Comparative Examples 1 and 2 are conventional materials in which LC> 1 and RC <80, and WC> 6. Comparative Example 1 is a urethane material, and Comparative Example 2 is a non-woven fabric laminated with a fabric made of knitted fabric or woven fabric such as a tengu, a milling cutter, or a tricot. The characteristic values of Comparative Example 1 are LC = 1.820, WC = 8.719 (gf / cm ² ), RC = 49.24 (%), T ₀ = 5.352 (mm), TM = 3.434. (Mm). The characteristic values of Comparative Example 2 are LC = 1.504, WC = 1.775 (gf / cm ² ), RC = 77.02 (%), T ₀ = 5.182 (mm), TM = 4.508 (Mm).

FIG. 6 is a diagram schematically showing a difference in compression characteristics between the pad material according to the example and the pad material according to the comparative example. In the example shown in the figure, the compression characteristic of Comparative Example 1 is indicated by X1, and the compression characteristic of Comparative Example 2 is indicated by X2. The compression characteristics of Examples 1 to 3 are indicated by Y.

When these compression characteristics are analyzed, the conventional urethane material of Comparative Example 1 has a relatively high overall compressibility, but there is a tendency that both the compressibility with respect to initial compression and the recoverability after compression tend to be low. I understand. Moreover, although the nonwoven fabric of the comparative example 2 has high compressibility with respect to initial compression and the recoverability after compression compared with the comparative example 1, it turns out that there exists a tendency for the whole compressibility to be low. On the other hand, in the urethane materials of Examples 1 to 3, the ease of compression with respect to the initial compression is sufficiently higher than those of Comparative Examples 1 and 2, and the overall ease of compression is equal to or higher than that of Comparative Example 1. Further, the recoverability after compression was equal to or higher than that of Comparative Example 2.

As described above, in the pad material 14, when the urethane material satisfying LC ≦ 1 and RC ≧ 80 is used, the compressibility is easily applied when the compression load is applied, and the compression load is released. Both resilience and recovery are ensured. Therefore, in the garment with a cup part 1 in which the pad 11 constituted by the pad material 14 is arranged at least in the lower cup part, the pressure applied from the lower cup part to the lower part of the bust is suppressed, and the total amount of pressure applied to the bust is effective. Can be reduced. In addition, by ensuring the compressibility and recoverability of the pad 11, the flexibility, lightness, and softness of the cup portion 2 are enhanced, and both the bust formability and the comfort can be achieved. Furthermore, the pad material 14 uses a urethane material that further satisfies WC ≧ 6. For this reason, the ease of compression when a compressive load is applied is further improved, and the pressure applied from the lower cup portion to the lower portion of the bust can be more suitably suppressed.

FIG. 7 is a diagram showing the analysis result of the contact pressure of the cup part to which the cup part material is applied. In the analysis shown in the figure, the entire cup part is made of a sample A, the upper cup part is made of the same material as the pad material 14, and the lower cup part is made of a non-woven cloth. For each of Sample C, which is formed of a non-woven fabric and whose lower cup portion is formed of the same material as the pad material 14, and Sample D, in which the entire cup portion is formed of the same material as the pad material 14, from the lower cup portion. This is a measurement of the pressure applied to the bust.

As shown in FIG. 7, in the case of sample A and sample B, as shown in FIG. 7, the pressure applied to the bust from the lower cup (the points B, C, and D in FIG. 11A). Whereas the total value) was 5.5 kPa or more, in the case of Sample C and Sample D, the pressure applied to the bust from the lower cup (the points B, C, and D in FIG. 11A) The total pressure) was 3.0 kPa or less. Therefore, by applying the cup part material according to one aspect of the present invention to at least the lower cup part, the pressure applied from the lower cup part to the lower part of the bust is suppressed to about half, and the total amount of the pressure applied to the bust is effective. It was concluded that it can be reduced.

Further, FIG. 8 is a diagram showing the monitoring test results of the cup part to which the cup part material is applied. In the monitor test shown in the figure, for each of the samples A to D shown in FIG. 7, the subjective comfort of the garment with the cup portion is evaluated by a plurality of monitors. The evaluation items for wearing comfort were three items: flexibility, lightness, and softness. Each item was evaluated on a five-point scale (+2, +1, 0, -1, -2), and the average value of responses from each monitor was defined as the subjective value. The higher the subjective value (the more toward the + side), the softer, lighter, and softer the feeling of wear. The smaller the subjective value (toward the-side), the harder, heavier, and the more worn feeling Show.

As a result, in Sample A and Sample B, the subjective values were negative in all three items, but in Sample C and Sample D, the subjective values were positive in all three items. That is, Sample A and Sample B in which the cup part material according to one aspect of the present invention is not applied to the lower cup part, and Sample C and Sample D in which the cup part material according to the present invention is applied to at least the lower cup part. And, it was found that there was a significant difference in the evaluation of wearing comfort.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the pad 11 is formed using the pad material 14 and the cup portion 2 of the type in which the pad 11 is applied to the pocket 12 of the cup portion 2 is shown. However, as shown in FIG. You may comprise the cup part 2 with the pad side skin side fabric 22 which arrange | positions the cup part raw material 24 which has a compression characteristic equivalent to the raw material 14 inside.

In this embodiment, the padded skin side fabric 22 is lower than the lower edge portion 22a along the upper side portion 3a of the base portion 3 and the end portion on the front center A side of the lower edge portion 22a than the upper edge portion 2a of the cup portion 2. It has an upper edge portion 22b that extends downward and faces the side edge portion 2b, and a side edge portion 22c that extends along the side edge portion 2b of the cup portion 2. The pad side skin 22 incorporates a cup part material 24 so as to have substantially the same shape as the pad 11 shown in FIG. 3, and the cup part material 24 is positioned in the lower cup part. 2 is arranged on the skin side. The lower edge portion 22a is sewn to the upper side portion 3a, the upper edge portion 22b is sewn to a position below the upper edge portion 2a in the cup portion 2, and the side edge portion 22c is sewn to the side edge of the cup portion 2. It is sewn to the part 2b.

Also in such a form, similarly to the above embodiment, the pressure applied from the lower cup part to the lower part of the bust is suppressed, and the total amount of pressure applied to the bust can be effectively reduced. Moreover, the softness | flexibility of a cup part 2, a lightweight feeling, and a soft feeling are raised, and it can be compatible with the modeling property and wearing comfort of a bust.

Further, for example, in the above embodiment, a brassiere is illustrated as a garment with a cup part, but as a garment with a cup part to which the present invention is applied, in addition to a brassiere, a foundation garment such as a bra slip, a bra camisole, a body suit, and a swimsuit And leotard. The features of the present invention are also applicable to all types of brassieres, such as full cup brassiere, 3/4 cup brassiere, and 1/2 cup brassiere. The sewing of the cup part can take various forms such as 1 dart contact, 2 dart contact, 2 sheet contact, 3 sheet contact, gathers only, no sewing (molded cup).
