Description

本発明は部分的に異なる通気度を有する布帛であって、衣類として用いた場合望むべき部分の通気度を適宜設定することが可能となり、また更に伸縮性差を付与することにより、部分的に着圧差を持たせることで体型補正機能又は筋肉サポート機能を有する使用快適性に優れた衣類に用いられる布帛およびその製造方法、これを用いた衣類に関するものである。   The present invention is a fabric having partially different air permeability, and when used as clothing, it is possible to appropriately set the air permeability of a portion that is desired, and further by providing a difference in stretchability, The present invention relates to a fabric used for a garment that has a body shape correcting function or a muscle support function by giving a pressure difference and is excellent in use comfort, a manufacturing method thereof, and a garment using the fabric.

従来、衣類に部分的に異なる通気度を付与する為には、通気度の高いメッシュ組織や開口組織、絡み織り組織、模紗組織等の組織を有する布帛を、通気度の低い布帛の一部分に用いる方法や、これらの組織をジャガード機構やドビー機構で布帛の一部分に形成する手法が用いられてきた。   Conventionally, in order to impart a partially different air permeability to a garment, a cloth having a highly air-permeable mesh structure, an opening structure, an entangled weave structure, an imitation structure, or the like is used as a part of a cloth having a low air permeability. The method used and the method of forming these structures on a part of the fabric by the jacquard mechanism or the dobby mechanism have been used.

特許文献1には、開口部を設けない手法として太糸、細糸を用い、どちらか一方の糸がニットされた度目において、他方の糸がミス又はタックした組織を取る組織変更手法により異なる通気度を付与することが開示されている。
しかしながら、製織製編の段階で製品に使用する部位を想定した組織を決定して布帛を作成しなければならず、通気度の変更や、デザインの変更に対する生産のリードタイムが長く柔軟性に劣るものであった。
In Patent Document 1, a thick yarn and a fine yarn are used as a method of not providing an opening, and each time one of the yarns is knitted, the ventilation changes depending on the tissue change method in which the other yarn is missed or tacked. Giving a degree is disclosed.
However, it is necessary to create a fabric by determining a structure that assumes the part to be used in the product in the weaving and knitting stage, and the production lead time for the change in air permeability and the design is long and the flexibility is inferior. It was a thing.

さらに特許文献2には、ガードル等において裏側から弾力性ある比較的幅広のテープ状布帛を重ねて縫製する方法、弾力性ある樹脂を部分的に塗布する方法が記載されている。
しかしながら、布帛を重ね縫製する場合は、生産性が低く、かつ重ね縫製した部位は肉厚となる為、通気度が著しく低下し、着用時の蒸れ感が高いものであった。また、布帛に段差が生じるために、アウターを着用しても段差が外観上に現れ、着用者の不満感が出るものであった。
さらに、樹脂剤の塗布を行う方法では、風合いが劣ると共に、布帛の織編目が閉塞し、通気度が著しく低下、蒸れ感が高いものであった。
Further, Patent Document 2 describes a method of laminating and sewing a relatively wide tape-like fabric having elasticity from the back side in a girdle or the like, and a method of partially applying an elastic resin.
However, when fabrics are lap stitched, productivity is low and the lap stitched portions are thick, so the air permeability is remarkably reduced and the feeling of stuffiness when worn is high. Moreover, since a level | step difference arises in the fabric, even if the outer was worn, a level | step difference appeared on the external appearance and the wearer's dissatisfaction feeling came out.
Further, in the method of applying the resin agent, the texture is inferior, the woven stitches of the fabric are blocked, the air permeability is remarkably lowered, and the feeling of stuffiness is high.

更に特許文献3には、ジャガード機構を用いた編機を使用し、部分的に編組織の変更、挿入する弾性糸の本数や太さを変化させることで部分的に着圧(伸長力、緊迫力)に差を持たせる事が開示されている。
メッシュ部位の開口部を大きくし、通気度を得る場合、肌の露出度が高くなり、着用者が心理的不快になりやすいものである。またジャガード機構が付属した特殊な編機を使用する必要があり、また製品型やサイズ毎に所定の編組織パターンの生地を製造する必要があるため、生産の柔軟性にかけるものであった。
Further, in Patent Document 3, a knitting machine using a jacquard mechanism is used, and the knitting structure is partially changed, and the number and thickness of elastic yarns to be inserted are partially changed so that the pressure (extension force, tightness) is partially increased. It is disclosed that there is a difference in power.
When the opening part of a mesh site | part is enlarged and air permeability is obtained, the exposure degree of skin becomes high and a wearer tends to become psychologically unpleasant. In addition, it is necessary to use a special knitting machine with a jacquard mechanism, and it is necessary to manufacture a fabric having a predetermined knitting structure pattern for each product type and size, which is a factor in production flexibility.

さらに、特許文献4には、変性ポリエステル繊維、ナイロン繊維並びに弾性繊維を含む布帛に抜蝕加工を行う方法が記載されているが、抜蝕部において、通気度が向上する事やストレッチ性が増すこと、布帛構成する繊維にてストレッチ性をコントロールするといった記載はなく、これらの繊維は単なる意匠(装飾)効果を上げるものとして用いられている。

Furthermore, Patent Document 4 describes a method of performing a discharging process on a fabric containing modified polyester fiber, nylon fiber, and elastic fiber. However, in the extracted part, the air permeability is improved and the stretch property is increased. In addition, there is no description that the stretchability is controlled by the fibers constituting the fabric, and these fibers are used merely to increase the design (decoration) effect.

本発明はこのような従来技術における肉厚感、蒸れ感といった問題点を解決するものであり、製品の望む部位へ通気度を付与した布帛である。   The present invention solves such problems of thickness and stuffiness in the prior art, and is a fabric in which air permeability is imparted to a desired part of a product.

本発明の第1の要旨は、部分的に異なる通気度を有する布帛であって、高通気度部位の通気度が低通気度部位の通気度の1.3倍以上、高通気度部位の布帛強度が150kpa以上である布帛にある。   The first gist of the present invention is a fabric having partially different air permeability, wherein the air permeability at the high air permeability portion is 1.3 times or more than the air permeability at the low air permeability portion, and the fabric at the high air permeability portion. The fabric has a strength of 150 kpa or more.

本発明の第2の要旨は、本発明の布帛を用いた、ガードル、ボディスーツ、レオタード、ショーツ、ブラジャー、スパッツ、スポーツ用タイツ、スポーツ用インナー、靴下、水着から選ばれた衣類にある。   The second gist of the present invention is a garment selected from the girdle, body suit, leotard, shorts, bra, spats, sports tights, sports inner, socks and swimsuit using the fabric of the present invention.

本発明の第3の要旨は、1)〜4)を満たすストレッチ性ベース布帛の任意の箇所に抜蝕促進剤を含む抜蝕糊を印捺する工程1と、抜蝕剤により印捺部の抜蝕性繊維aの一部または全部を除去する抜蝕加工工程2を施すことを含む、部分的に異なる通気度を有する布帛の製造方法にある。1)ストレッチ性ベース布帛は抜蝕性繊維aと、非抜蝕性繊維bと、非抜蝕性繊維cとで構成され、2)抜蝕性繊維aは、抜蝕剤により溶解するポリマーにて少なくともその一部が構成され、3)非抜蝕性繊維bは、前記抜蝕剤には溶解せず、かつ伸縮性を有し、4)非抜蝕性繊維cは、前記抜蝕剤には溶解せず、かつ非伸縮性である。   The third gist of the present invention is the step 1 of printing the discharge paste containing the discharge accelerator on any part of the stretchable base fabric satisfying 1) to 4), and the printing part by using the discharge agent. The present invention resides in a method for manufacturing a fabric having partially different air permeability, including performing an extraction process step 2 for removing part or all of the extractable fibers a. 1) Stretchable base fabric is composed of extractable fibers a, nonextractable fibers b, and nonextractable fibers c. 2) The extractable fibers a are made of a polymer that is dissolved by the extractant. And 3) the non-extractable fiber b does not dissolve in the extractant and has elasticity, and 4) the nonextractable fiber c is the extractant. Does not dissolve in and is non-stretchable.

本発明によれば、任意の箇所の通気度に差を持たせた布帛が得られ、更に異なる伸縮性も付与した布帛を得る事が可能となる。例えば前記布帛を、体型補正機能を有するインナーに用いた場合、低伸縮性の補正部において肉厚感が少なく、また体型に追従する高伸縮性の部位では着用時の不快感の原因となる蒸れ感等が解消された衣類とすることが出来る。また筋肉の動きを阻害しない(筋肉サポート)機能を必要とする、いわゆる第2のスキン型とされるインナーに用いられた場合、発汗しやすい部分(例えば、脇の下部、背中部、胸部等)に通気度を向上させた快適な衣類とすることが出来る。   According to the present invention, it is possible to obtain a fabric having a difference in air permeability at an arbitrary location, and to obtain a fabric having different elasticity. For example, when the fabric is used as an inner having a body shape correcting function, the low stretchable correction portion has less thickness, and the highly stretchable portion that follows the body shape causes stuffiness that causes discomfort during wearing. It can be set as clothing in which the feeling is eliminated. In addition, when it is used for the so-called second skin-type inner that requires a function that does not inhibit muscle movement (muscle support), it can be applied to areas that are prone to sweat (eg, underarms, back, chest, etc.) Comfortable clothing with improved air permeability.

また特殊な機構を備えた編機を使用することなく、抜蝕加工の型を変更するだけで、布帛強度の低下を抑制しながら、布帛の任意の箇所に、所望とする形状に部分的に通気度の高い部分を形成すると共に、ストレッチ性のより高い部分を形成させることが可能となるものであり、生産効率良く得ることができるものである。   Also, without using a knitting machine equipped with a special mechanism, it is possible to partially change the shape of the desired shape at any location on the fabric while suppressing a decrease in fabric strength by simply changing the die of the removal process. While forming a part with high air permeability, it becomes possible to form a part with higher stretchability, and can be obtained with high production efficiency.

以下、本発明の好適な実施の形態について具体的に説明する。   Hereinafter, preferred embodiments of the present invention will be specifically described.

本発明の布帛は、部分的に異なる通気度を有する布帛であって、高通気度部位の通気度が低通気度部位の通気度の1.3倍以上である布帛であることが必要であり、1.5倍以上であることが好ましい。 The fabric of the present invention is a fabric having partially different air permeability, and it is necessary that the air permeability of the high air permeability portion is 1.3 times or more than the air permeability of the low air permeability portion. , 1.5 times or more is preferable.

高通気度部位の通気度が低通気度部位の通気度の1.3倍未満では、前記部位における高通気度を体感することができにくい。ガードル等製品とした際、パーツの大きさやデザインへの制約を少なくする為には、1.5倍以上あれば前記部位の面積を小さくすることが可能となることから好ましいものである。   When the air permeability at the high air permeability portion is less than 1.3 times the air permeability at the low air permeability portion, it is difficult to experience the high air permeability at the portion. When a product such as a girdle is used, in order to reduce restrictions on the size and design of the part, it is preferable that the area is 1.5 times or more because the area of the part can be reduced.

なお、本発明における通気度は、布帛を25℃、湿度65%条件の環境可変室で12時間調整し、JIS L1018一般試験方法(フラジール形試験)に従って、テクステスト社製、通気度試験機FX3300で測定をおこない、通気度(cm3/cm2/sec)を求めた。   The air permeability in the present invention is adjusted for 12 hours in an environment variable room under conditions of 25 ° C. and 65% humidity, and according to JIS L1018 general test method (fragile type test), manufactured by Tex Test Co., Ltd., air permeability tester FX3300 The air permeability (cm3 / cm2 / sec) was determined.

また高通気度部位の布帛強度は、150kPa以上有することが必要である。更に190kpa以上が好ましい。150kPa未満では、薄地のストレッチ布帛の場合では、30%を超えるような伸長時に布帛が裂けやすくなってしまう。   The fabric strength at the high air permeability portion must be 150 kPa or more. Furthermore, 190 kpa or more is preferable. If it is less than 150 kPa, in the case of a thin stretch fabric, the fabric tends to tear when stretched to exceed 30%.

本発明の布帛は、高通気度部位が、低通気度部位に対し、高い伸縮性を有し、少なくとも布帛の経緯方向のいずれか一方の、低通気度部位に対する高通気度部位の伸長率比が1.1〜5.5倍、低通気度部位に対する高通気度部位の30%伸長時応力比が0.05〜0.9倍の伸縮性差を有することが好ましい。   In the fabric of the present invention, the high air permeability portion has high stretchability with respect to the low air permeability portion, and the elongation ratio of the high air permeability portion to the low air permeability portion in at least one of the weft directions of the fabric. Is preferably 1.1 to 5.5 times, and the stress ratio at 30% elongation of the high air permeability portion with respect to the low air permeability portion is 0.05 to 0.9 times.

低通気度部位に対する高通気度部位の伸長率比は、1.5〜5.0の範囲であることがさらに好ましい。この比率が1.1倍未満であると、筋肉サポート機能を有する衣類に用いた場合に部分的に十分な着圧差を付与できない。また、5.5倍を超えると布帛強度が著しく低下し、伸びの戻りが悪く好ましくない。   The elongation ratio of the high air permeability portion to the low air permeability portion is more preferably in the range of 1.5 to 5.0. When this ratio is less than 1.1 times, a sufficient wearing pressure difference cannot be imparted partially when used for clothing having a muscle support function. On the other hand, if it exceeds 5.5 times, the fabric strength is remarkably lowered, and the return of elongation is not preferable.

低通気度部位に対する高通気度部位の30%伸長時応力比は、0.1〜0.06の範囲であることがさらに好ましい。この比率が0.05倍未満であると、高通気度部位の布帛強度が著しく低下し、好ましくない。また、高通気度部位の30%伸長時応力比が0.90倍を超えると、衣類として着用した際サポート感、締め付け感の差を体感し難くなり好ましくない。   The stress ratio at 30% elongation of the high air permeability portion with respect to the low air permeability portion is more preferably in the range of 0.1 to 0.06. When this ratio is less than 0.05 times, the fabric strength at the high air permeability portion is remarkably lowered, which is not preferable. Further, if the stress ratio at 30% elongation of the high air permeability portion exceeds 0.90 times, it is difficult to experience the difference between the feeling of support and the feeling of tightening when worn as clothing, which is not preferable.

一般に織編物は、織編物の種類及び組織、構成する糸の種類、配列等によって、経緯の伸縮特性に差が有るものであるが、本発明の布帛は、高通気度部位と低通気度部位である基布部の伸縮特性により大きく差が発現する方向についての伸縮特性について規定するものである。   In general, a woven or knitted fabric has a difference in the expansion and contraction characteristics of the background depending on the type and structure of the woven or knitted fabric, the type and arrangement of yarns, and the fabric of the present invention has a high air permeability portion and a low air permeability portion. It defines the expansion / contraction characteristics in the direction in which a large difference is caused by the expansion / contraction characteristics of the base fabric portion.

本発明の伸長率の比率とは、測定に用いる試料(巾2.5cm×長さ3cm)当り14.7N(1.5kgf)時の伸長率を織編物の経及び緯方向について高通気度部位と低通気度部位である基布部の伸長率を測定し、同方向での伸長率の比が大きい方向の数値で規定する。   The ratio of the elongation rate of the present invention means the elongation rate at 14.7 N (1.5 kgf) per sample (width 2.5 cm × length 3 cm) used for the measurement, and the high air permeability portion in the warp and weft directions of the woven or knitted fabric And the elongation rate of the base fabric part which is a low air permeability part is measured, and it prescribes | regulates with the numerical value of the direction where the ratio of the elongation rate in the same direction is large.

また30%伸長時応力の比率とは、布帛の経及び緯方向についてサンプル巾2.5cm当りの30%伸長時における伸長応力を、高通気度部位と低通気度部位である基布部で測定し、同方向での比が小さい方向の数値で規定する。   The ratio of the stress at 30% elongation is the measurement of the elongation stress at 30% elongation per 2.5 cm sample width in the warp and weft directions of the fabric at the base fabric part which is the high air permeability part and the low air permeability part. However, it is defined by a numerical value in a direction where the ratio in the same direction is small.

さらに本発明の布帛は、製品着用時を想定した伸長状態においての通気度差が更に向上する事が好ましい。布帛の種類及び組織、構成する糸の種類、配列等によって、布帛の経緯の伸縮特性に差が有るものであるが、経かつ緯方向に15%伸長させた状態を木枠で固定し着用時の伸長状態として規定し、通気度を測定した。   Furthermore, it is preferable that the fabric of the present invention further improves the difference in air permeability in the extended state when the product is worn. Depending on the type and structure of the fabric, the type of yarn, the arrangement, etc., there are differences in the warp and stretch properties of the fabric, but when worn with a wooden frame fixed in the warp and weft direction by 15% The air permeability was measured.

経かつ緯方向に15%伸長させた状態での高通気度部位の通気度が、経かつ緯方向に15%伸長させた状態での低通気度部位の1.5倍以上有するが好ましく、2〜5倍の範囲であることがさらに好ましい。   Preferably, the air permeability of the high air permeability portion in the state extended by 15% in the warp and weft direction is 1.5 times or more than the low air permeability portion in the state extended by 15% in the warp and weft direction. More preferably, it is in the range of 5 times.

また、通気度の比が、1.5倍未満であると製品を着用した場合においては、通気度が更に向上したとは言い難く、更に2倍以上あれば蒸れ感の軽減を更に体感することが可能となる。 In addition, when the product is worn when the air permeability ratio is less than 1.5 times, it is difficult to say that the air permeability is further improved. Is possible.

さらに本発明の布帛は、高通気度部位が、ストレッチ性を有する繊維とストレッチ性を有さない繊維からなる抜蝕加工を施された部位であり、低通気度部位の伸長率よりも大きいことが好ましい。   Further, in the fabric of the present invention, the high air permeability portion is a portion subjected to a discharge process composed of fibers having stretch properties and fibers having no stretch properties, and is larger than the elongation rate of the low air permeability portions. Is preferred.

さらに本発明の布帛は、アルカリ金属スルホン酸基を有する第三成分により変性されたポリエステル繊維を含むことが好ましい。アルカリ金属スルホン酸基を有する第三成分により変性されたポリエステル繊維を用いることで、低通気度部位にソフトな風合いを付与し、また鮮明度の高いカチオン染料染色が可能となる。   Furthermore, the fabric of the present invention preferably contains a polyester fiber modified with a third component having an alkali metal sulfonic acid group. By using a polyester fiber modified with a third component having an alkali metal sulfonic acid group, a soft texture can be imparted to a low air permeability portion, and a cationic dye can be dyed with high definition.

本発明の布帛は、製品として使用した際、部位によって通気度に差が必要とされる衣類に用いられ、好ましくはガードル、ボディスーツ、レオタード、ショーツ、ブラジャー、スパッツ、スポーツ用タイツ、スポーツ用インナー、靴下、水着から選ばれた衣類に用いることが望ましい。   The fabric of the present invention is used for clothing that requires a difference in air permeability depending on the part when used as a product, and preferably girdle, body suit, leotard, shorts, bra, spats, sports tights, sports inners. It is desirable to use for clothing selected from socks and swimwear.

次に本発明の布帛の製造方法について説明する。 Next, the manufacturing method of the fabric of this invention is demonstrated.

本発明の部分的に異なる通気度差を有する布帛は、1)〜4)を満たすストレッチ性ベース布帛の任意の箇所に抜蝕促進剤を含む抜蝕糊を印捺する工程1と、抜蝕剤により印捺部の抜蝕性繊維aの一部または全部を除去する抜蝕加工工程2を施すことを含む、部分的に異なる通気度を有する布帛の製造方法により得られる。1)ストレッチ性ベース布帛は抜蝕性繊維aと、非抜蝕性繊維bと、非抜蝕性繊維cとで構成され、2)抜蝕性繊維aは、抜蝕剤により溶解するポリマーで構成され、3)非抜蝕性繊維bは、前記抜蝕剤には溶解しないポリマーで構成され、かつ伸縮性を有し、4)非抜蝕性繊維cは、前記抜蝕剤には溶解しないポリマーで構成され、かつ非伸縮性である
本発明における布帛のベース布帛は、抜蝕剤により溶解するポリマーにて少なくともその一部が構成された抜蝕性繊維aと、前記抜蝕剤には溶解しないポリマーであり、かつ伸縮性の非抜蝕性繊維bと、前記抜蝕剤には溶解しないポリマーであり、かつの非伸縮性の非抜蝕性繊維cとで構成されることが必要である。
A fabric having a partially different air permeability difference according to the present invention includes a step 1 of printing a discharge paste containing a discharge accelerator on an arbitrary portion of a stretch base fabric satisfying 1) to 4), and a discharge It is obtained by a method for producing a fabric having partially different air permeability, which includes performing an erosion process 2 in which a part or all of the erodible fibers a in the printed part is removed with an agent. 1) The stretchable base fabric is composed of an extractable fiber a, a non-extractable fiber b, and a nonextractable fiber c. 2) The extractable fiber a is a polymer that is dissolved by an extractant. 3) The non-extractable fiber b is composed of a polymer that does not dissolve in the extractant and has elasticity, and 4) the nonextractable fiber c is dissolved in the extractant. The base fabric of the fabric according to the present invention is composed of a non-stretchable polymer, and the extractable fiber a, at least part of which is composed of a polymer dissolved by the extractant, and the extractant Is a non-dissolvable polymer and stretchable non-extractable fiber b, and a non-stretchable non-extractable fiber c that is a polymer that does not dissolve in the above-mentioned extractant. is necessary.

ベース布帛を構成する抜蝕性繊維aは、抜蝕加工に使用する抜蝕剤により溶解するポリマーにて少なくともその一部が構成された繊維であり、また抜蝕剤により溶解するポリマーと前記抜蝕剤によっては溶解しない非抜蝕性ポリマーとからなる複合繊維等の繊維であってもよい。   The extractable fiber a constituting the base fabric is a fiber that is at least partly composed of a polymer that is dissolved by an extractant used for the removal process. It may be a fiber such as a composite fiber composed of a non-extractable polymer that does not dissolve depending on the erosive agent.

また、抜蝕促進剤を含む抜蝕糊を印捺する工程で用いる抜蝕促進剤としては、ジエタノールアミン、トリエタノールアミン等のアミン、多価アルコールにエチレンオキシドを2モル以上付加した多価アルコールエチレンオキシド付加物、多価アルコールエチレンオキシド付加物と第四級アンモニウム塩の併用等が挙げられ、これらの抜蝕促進剤を使用し、かつ抜蝕剤として水酸化ナトリウム等を熱水状態のアルカリ水溶液として使用する場合は、抜蝕性繊維aとして、通常のポリエステル繊維よりも高溶解性を有する抜蝕性の繊維としてアルカリ金属スルホン酸基を有する第三成分により変性されたポリエステル繊維を用いることが好ましく、アルカリ金属スルホン酸基を有する第三成分により変性されたポリエステル繊維を用いることで、印捺部と非印捺部との抜蝕度合の差を大きくすることができる。   In addition, as an extraction accelerator used in the process of printing an extraction paste containing an extraction accelerator, an amine such as diethanolamine or triethanolamine, a polyhydric alcohol ethylene oxide addition in which 2 mol or more of ethylene oxide is added to a polyhydric alcohol Products, polyhydric alcohol ethylene oxide adducts and quaternary ammonium salts are used in combination, and these removal accelerators are used, and sodium hydroxide or the like is used as a hot water alkaline aqueous solution as a removal agent. In this case, it is preferable to use a polyester fiber modified with a third component having an alkali metal sulfonic acid group as an extractable fiber a having higher solubility than a normal polyester fiber as the extractable fiber a. By using a polyester fiber modified with a third component having a metal sulfonic acid group, The difference in the fiber-decomposed degree of 捺部 and Hishirushi 捺部 can be increased.

従って、例えば、抜蝕性繊維aとして、レーヨンとアルカリ金属スルホン酸基を有する第三成分により変性されたポリエステル繊維を併用した場合、抜蝕性繊維aに応じて、抜蝕剤を部分的に印捺する工程と、抜蝕剤により抜蝕性繊維aを溶解除去する工程とを、抜蝕剤を変えて繰り返して施すことができる。   Thus, for example, when the polyester fiber modified with rayon and the third component having an alkali metal sulfonic acid group is used as the extractable fiber a, the extractant is partially applied depending on the extractable fiber a. The step of printing and the step of dissolving and removing the extractable fibers a with the extractant can be repeated by changing the extractant.

本発明においては、特に、抜蝕性繊維aとして、アルカリ金属スルホン酸基を有する第三成分により変性されたポリエステル繊維が好ましいものとして挙げられ、この変性ポリエステル繊維は、アルカリ金属スルホン酸基を有する第三成分により変性されたポリエステルポリマーのみからなる繊維であってもよいし、アルカリ金属スルホン酸基を有する第三成分により変性されたポリエステルポリマーと、抜蝕剤には溶解しない非抜蝕性ポリマーとの複合構造の複合繊維であってもよい。複合繊維の複合構造は、アルカリ金属スルホン酸基を有する第三成分により変性されたポリエステルポリマーが繊維表面に露出して存在する複合構造であることが好ましく、複合構造の繊維は、抜蝕加工後に抜蝕剤には不溶解の非抜蝕性ポリマーが細繊維として残存することによって布帛の強度保持に寄与する点からより好ましいものである。   In the present invention, polyester fiber modified with a third component having an alkali metal sulfonic acid group is particularly preferred as the extractable fiber a, and the modified polyester fiber has an alkali metal sulfonic acid group. It may be a fiber composed only of a polyester polymer modified by a third component, or a polyester polymer modified by a third component having an alkali metal sulfonic acid group, and a non-exhaustable polymer that does not dissolve in an extractant.

ベース布帛は、抜蝕性繊維aと、伸縮性の非抜蝕性繊維bと、非伸縮性の非抜蝕性繊維cとから構成される織物或いは編物であるが、明瞭に異なるストレッチ性を付与するうえでストレッチ性の差を大きくすることが望ましく、ストレッチ性の差を大きくするためには、被加工布帛であるベース布帛自体が組織構造上ストレッチ性を発揮し易いという点から、編物であることが好ましく、この場合、高伸縮性部位における通気度も高くなる。編物としては、経編地であるラッセル編地、トリコット編地、緯編地である丸編地、横編地等が挙げられ、他にジャガード機構を備えた編機によった柄を有する編地、多層構造編地、レース基布編地等が挙げられる。   The base fabric is a woven or knitted fabric composed of the extractable fiber a, the stretchable non-exhaustable fiber b, and the non-stretchable non-exhaustable fiber c. When applying, it is desirable to increase the difference in stretchability, and in order to increase the difference in stretchability, the base fabric itself, which is the fabric to be processed, is easy to exert stretchability in terms of tissue structure. In this case, the air permeability at the highly stretchable part is also high. Examples of the knitted fabric include a raschel knitted fabric that is a warp knitted fabric, a tricot knitted fabric, a circular knitted fabric that is a weft knitted fabric, a flat knitted fabric, and a knitted fabric having a pattern by a knitting machine equipped with a jacquard mechanism. Examples thereof include a ground, a multilayered knitted fabric, and a lace base fabric knitted fabric.

ベース布帛における抜蝕性繊維a、伸縮性の非抜蝕性繊維b、非伸縮性の非抜蝕性繊維cの繊維形態は、それぞれの機能を発揮させる点からフィラメント糸であることが好ましく、各繊維の繊度、構成比率は、任意に選択され、特に制限はない。好ましく用いられる編物においては、各繊維は編組織によってそれぞれの組織を構成する糸として用いられるが、伸縮性の非抜蝕性繊維bを編物のストレッチ性により支配的に寄与させるため、伸縮性の非抜蝕性繊維bは、挿入糸として、抜蝕性繊維aと非伸縮性の非抜蝕性繊維cは、地編の構成糸として、それぞれ用いることが好ましい。   The fiber form of the extractable fiber a, the stretchable non-extractable fiber b, and the non-stretchable non-extractable fiber c in the base fabric is preferably a filament yarn from the viewpoint of exerting the respective functions. The fineness and composition ratio of each fiber are arbitrarily selected and are not particularly limited. In the knitted fabric that is preferably used, each fiber is used as a yarn constituting the respective structure by the knitted structure, but in order to make the stretchable non-exhaustable fiber b dominantly contribute to the stretchability of the knitted fabric, The non-extractable fibers b are preferably used as insertion yarns, and the non-extractable fibers a and the non-stretchable non-extractable fibers c are preferably used as constituent yarns of the ground fabric.

前記ストレッチ性ベース布帛に施す抜蝕加工には、抜蝕促進剤を含む抜蝕糊を部分的に印捺する工程と、抜蝕剤により印捺部の抜蝕性繊維aの一部または全部を溶解除去する工程とを含む一般的に使用されている公知の方法が使用される。抜蝕促進剤を含む抜蝕糊を印捺する工程では、抜蝕促進剤を糊剤に含有させて抜蝕糊として印捺する。抜蝕促進剤としては前述したとおりであり、抜蝕糊に用いる糊剤としては、特に限定はなく、公知の糊剤が用いられ、例えば小麦澱粉、トラガントガム、ローカストビーンガム、グアガム、ポリビニルアルコール、ポリアクリル酸ソーダ等の糊剤が単独または2種以上組み合わせて用いられる。   For the discharging process applied to the stretchable base fabric, a step of partially printing the discharging paste containing the discharging accelerator, and a part or all of the discharging fibers a of the printing portion by the discharging agent. In general, a well-known method including a step of dissolving and removing the lysate is used. In the step of printing the discharge paste containing the discharge accelerator, the discharge accelerator is included in the paste and printed as the discharge paste. The extraction accelerator is as described above, and the paste used for the extraction paste is not particularly limited, and known pastes are used, such as wheat starch, tragacanth gum, locust bean gum, guar gum, polyvinyl alcohol, A paste such as sodium polyacrylate is used alone or in combination of two or more.

抜蝕糊の印捺には、型を用いて部分的に印捺するのがよく、ストレッチ性に差を付けようとするストレッチ性ベース布帛の任意の箇所に、抜蝕部の大きさ、抜蝕部の柄の形、抜蝕部の数、非抜蝕部に対する抜蝕部の面積比に応じ、適宜型を変更することによって印捺する。例えば比較的広領域の大きな柄からドットのような小さな柄まで任意の柄に対して型を変更することによって任意に得ることができる。この抜蝕剤を印捺する工程には、抜蝕糊の印捺後、乾燥或いはさらに加熱処理等を含んでもよい。また、抜蝕性繊維aを除去する工程は、抜蝕剤によって抜蝕性繊維aを構成するポリマー(但し、抜蝕剤により溶解するポリマー)を全て溶解することにより、抜蝕性繊維aの一部または全部を除去するものであり、抜蝕性繊維aを除去する工程では、抜蝕剤の作用を活性状態にして抜蝕性繊維aを除去するが、蒸気、熱水等での湿熱処理、水洗、乾燥等を含んでもよい。また、湿熱抜蝕処理の前処理として、他の抜蝕促進剤を用いて抜蝕性繊維aの除去を促進或いは加速させることもできる。   It is good to print a part of the discharge paste using a mold, and the size of the part to be removed and the part to be removed can be applied to any part of the stretchable base fabric that will make a difference in stretchability. Printing is performed by appropriately changing the mold according to the shape of the pattern of the etched portion, the number of the removed portions, and the area ratio of the removed portion to the non-exposed portions. For example, it can be obtained arbitrarily by changing the pattern for an arbitrary pattern from a large pattern having a relatively wide area to a small pattern such as a dot. The step of printing the discharge agent may include drying or further heat treatment after printing the discharge paste. Further, the step of removing the extractable fiber a is performed by dissolving all the polymers constituting the extractable fiber a (however, the polymer dissolved by the extractant) with the extractant. In the step of removing part or all of the extractable fiber a, the action of the extractant is activated to remove the extractable fiber a. Heat treatment, washing with water, drying and the like may be included. Further, as a pretreatment of the wet heat removal treatment, the removal of the extractable fibers a can be promoted or accelerated by using another removal promotion agent.

かかる抜蝕加工を施してなる布帛における抜蝕部は、ストレッチ性ベース布帛を構成していた抜蝕性繊維aの全部が除去され、また一部が除去されないときには細繊維として存在するため、織編密度が低下し、繊維間に空隙ができ、通気度が向上すると共に、伸縮性の非抜蝕性繊維bと非伸縮性の非抜蝕性繊維cとの存在比率が相対的に高くなり、抜蝕部位での通気度が、非抜蝕部位より高くなる。また同時に、伸縮性の非抜蝕性繊維bに対する拘束力が低下し、伸縮性の非抜蝕性繊維bの動く自由度が増して、伸縮性の非抜蝕性繊維bがより伸びやすく、より縮みやすい状態が形成され、抜蝕部でのストレッチ性が非抜蝕部のストレッチ性より高くなり、抜蝕部と非抜蝕部ではストレッチ性に差が生ずる。   The erosion portion in the fabric formed by the erosion process is a woven fabric because all of the erosion fibers a constituting the stretch base fabric are removed, and when some of them are not removed, they are present as fine fibers. The knitting density is reduced, voids are formed between the fibers, the air permeability is improved, and the abundance ratio of the stretchable non-extractable fibers b and the non-stretchable nonextractable fibers c is relatively high. The air permeability at the extraction site is higher than that at the non-extraction site. At the same time, the restraining force on the stretchable non-exhaustable fiber b is reduced, the freedom of movement of the stretchable non-exhaustable fiber b is increased, and the stretchable non-exhaustable fiber b is more easily stretched. A more easily shrinkable state is formed, the stretchability at the extracted portion becomes higher than the stretch property at the non-extracted portion, and there is a difference in stretch properties between the extracted portion and the non-extracted portion.

得られた本発明の布帛は、ストレッチ性ベース布帛が本来有する通気度が低く、ストレッチ性の低い部分と、ストレッチ性ベース布帛より通気度が高く、ストレッチ性の高い部分を有する。通気度が高く、ストレッチ性が高くなる抜蝕部の部分は、抜蝕加工を施してなる布帛を衣類としたときに、非抜蝕部の部分より通気度が高く、着圧が低くなることから、部分的に通気度差と着圧差が生じる衣類となる。   The obtained fabric of the present invention has a portion having a low breathability inherent in the stretchable base fabric and a portion having a low stretchability and a portion having a higher breathability and a higher stretchability than the stretchable base fabric. The part of the extracted part where the air permeability is high and the stretchability is high, when the cloth formed by the discharge process is used as clothing, the air permeability is higher than the part of the non-extracted part and the pressure is lower. Therefore, the garment has a difference in air permeability and pressure difference partially.

本発明においては、衣類としたときに部分的に通気度差と着圧差が生じさせるため、抜蝕加工を施すことにより、好ましくは、少なくとも布帛の経緯方向のいずれか一方の、非抜蝕部と抜蝕部との間に、抜蝕部に対する抜蝕部の伸長率比が1.1〜5.5倍、非抜蝕部に対する抜蝕部の30%伸長時応力比が0.9〜0.05倍のストレッチ性差を付与する。   In the present invention, when the garment is used, a difference in air permeability and a pressure difference is caused in part. Therefore, by performing a discharge process, it is preferable that at least one of the non-exhaust parts in the weft direction of the fabric. The elongation ratio of the extracted portion relative to the extracted portion is 1.1 to 5.5 times between the exposed portion and the extracted portion, and the 30% elongation stress ratio of the extracted portion relative to the non-extracted portion is 0.9 to Gives a stretch difference of 0.05 times.

本発明において、特に好ましい態様の例を挙げると、抜蝕性繊維aがアルカリ金属スルホン酸基を有する第三成分により変性されたポリエステル繊維、伸縮性の非抜蝕性繊維bがポリウレタン繊維、非伸縮性の非抜蝕性繊維cがポリアミド繊維であり、アルカリ金属スルホン酸基を有する第三成分により変性されたポリエステル繊維がカチオン染料に対する可染性、ポリアミド繊維が酸性染料、反応性染料に対する可染性をそれぞれ示すことから、これらの繊維の組み合わせのときには、染料の組み合わせによって、抜蝕加工後に染色加工を施したときに異色染めを可能にし、ベース布帛に、部分的に通気度差と、ストレッチ性の差を付与するとともに、抜蝕加工での透かし効果に加え、部分的な異色効果を付与し、得られる布帛の意匠性効果を高める。この染色加工には、特に制限はなく、通常の方式、例えば浸染が用いられる。   In the present invention, examples of particularly preferred embodiments include polyester fibers in which the extractable fiber a is modified with a third component having an alkali metal sulfonic acid group, stretchable non-exhaustable fibers b are polyurethane fibers, non-extractable fibers The stretchable non-exhaustable fiber c is a polyamide fiber, the polyester fiber modified with a third component having an alkali metal sulfonic acid group is dyeable with a cationic dye, the polyamide fiber is dyeable with an acid dye and a reactive dye. Since each of the dyeing properties is shown, when the combination of these fibers is used, the combination of the dyes enables different color dyeing when the dyeing process is performed after the discharge process, and the base fabric partially has a difference in air permeability, In addition to providing a difference in stretchability, in addition to the watermark effect in the removal process, it also provides a partial discoloration effect. Increased. There is no restriction | limiting in particular in this dyeing process, A normal system, for example, dip dyeing, is used.

また、好ましく用いられる前記のアルカリ金属スルホン酸基を有する第三成分により変性されたポリエステル繊維は、抜蝕剤である水酸化ナトリウム等の熱水状態のアルカリ水溶液に対して良好な抜蝕性を呈し、抜蝕促進剤を含む抜蝕糊の印捺部で繊維を構成する溶解性ポリマーである変性ポリエステルポリマーのより完全な溶解除去が行われる。また、アルカリ金属スルホン酸基を有する第三成分により変性されたポリエステル繊維が抜蝕性繊維aとして含まれる布帛では、水酸化ナトリウム等の熱水状態のアルカリ水溶液によって、抜蝕促進剤を含む抜蝕糊の印捺部では変性されたポリエステル繊維が溶解除去され、また非印捺部では通常の未変性のポリエステル繊維に適用されると同様の減量加工が行われることになる。従い、非抜蝕性繊維cとして通常の未変性のポリエステル繊維が含まれる布帛では、印捺部での変性ポリエステル繊維の除去工程と減量加工と兼ねて行うことができ、風合い的にも多様な効果を付加することができる。   In addition, the polyester fiber modified with the third component having an alkali metal sulfonic acid group preferably used has good pitting properties with respect to a hot water alkaline aqueous solution such as sodium hydroxide as a pitting agent. The modified polyester polymer, which is a soluble polymer constituting the fiber, is printed and removed at the printing portion of the removal paste containing the removal accelerator. Moreover, in the fabric in which the polyester fiber modified with the third component having an alkali metal sulfonic acid group is included as the extractable fiber a, the extraction fiber containing the extractant is removed by a hot water alkaline aqueous solution such as sodium hydroxide. The modified polyester fiber is dissolved and removed in the printing portion of the adhesive paste, and the same weight reduction processing is performed in the non-printed portion when applied to a normal unmodified polyester fiber. Therefore, in the cloth containing normal unmodified polyester fiber as the non-exhaustable fiber c, it can be performed in combination with the removal process and weight reduction processing of the modified polyester fiber in the printing section, and various textures can be used. An effect can be added.

本発明においては抜蝕加工で抜蝕糊の印捺の際、抜蝕促進剤には影響されない染料を抜蝕糊に加え、抜蝕加工と同時に着色も可能であるが、抜蝕加工後に、染色加工を施すこともできる。また、本発明において、抜蝕加工を施し、必要により染色加工を施した後、布帛の非抜蝕部の一部に樹脂加工を施し、非抜蝕部のなかに部分的にストレッチ性差を付与することができる。樹脂加工は、樹脂をペースト状或いは液状となして塗布または含浸することによって付与し固着させる。樹脂加工に用いられる樹脂としては、仕上げ加工用の樹脂、例えば、ポリエステル系ウレタン重合体や、ポリエーテル系重合体、ポリアクリル酸系重合体、アミノ酸変性ウレタン系重合体、シリコンゴム系重合体等が挙げられ、これらのペースト状物或いは液状物をロータリースクリーン機やグラビア塗工機等によって付与後、乾燥させ固着させる。衣類とした場合、製品の外表面に樹脂加工することが、肌への好ましくない接触感を避けるうえでは好ましいが、製品外観を重視する場合には、製品の裏面への樹脂加工することもできる。また樹脂加工によって一般的に、不快な接触感や、通気度の低下が生じる傾向にあるが、この樹脂加工を全面塗布ではなく、ドット柄等の非連続な樹脂付着部の集合体とすることで、これらのデメリットを改善することもできる。   In the present invention, at the time of printing of the discharge paste in the discharge process, a dye that is not affected by the discharge accelerator is added to the discharge paste, and coloring can be performed simultaneously with the discharge process, but after the discharge process, It can also be dyed. Also, in the present invention, after performing a draining process and, if necessary, a dyeing process, a part of the non-excavated portion of the fabric is subjected to resin processing, and a difference in stretch properties is partially given in the non-excavated portion. can do. Resin processing is applied and fixed by applying or impregnating the resin in a paste or liquid form. Resins used for resin processing include finish processing resins such as polyester-based urethane polymers, polyether-based polymers, polyacrylic acid-based polymers, amino acid-modified urethane-based polymers, silicon rubber-based polymers, etc. These paste-like substances or liquid substances are applied by a rotary screen machine, a gravure coating machine or the like, and then dried and fixed. In the case of clothing, it is preferable to process the resin on the outer surface of the product in order to avoid unpleasant contact with the skin. However, if the product appearance is important, the resin can be processed on the back of the product. . Also, resin processing generally tends to cause an unpleasant contact feeling and a decrease in air permeability, but this resin processing should not be applied to the entire surface, but should be a collection of discontinuous resin adhesion parts such as dot patterns. These disadvantages can be improved.

樹脂加工が施された非抜蝕部の部分は、固着樹脂によって繊維の拘束力が増大して繊維の動きが抑制され、樹脂加工が施されていない非抜蝕部の部分に比べ、ストレッチ性が低いか若しくは極めて低い部分となる。したがい、樹脂加工を施して得られた本発明の布帛は、ストレッチ性ベース布帛が本来有する通気度が低く、ストレッチ性の低い部分、ストレッチ性ベース布帛より通気度が高く、ストレッチ性が高い部分、ストレッチ性ベース布帛より通気度が低く、ストレッチ性が低い部分を有する。また、通気度が低く、ストレッチ性が低くなる樹脂加工部分は、得られた布帛を衣類としたときに、非抜蝕部の樹脂加工を施していない部分より通気度が低下し、着圧が高くなることから、部分的に多段階の通気度差、および着圧差が生じる衣類となる。   The part of the non-exhaust part that has been subjected to resin processing is more stretchable than the part of the non-exhaust part that has not been subjected to resin processing, because the binding force of the fiber increases and the movement of the fiber is suppressed by the fixing resin. Is low or extremely low. Therefore, the fabric of the present invention obtained by applying the resin processing has a low breathability inherent in the stretchable base fabric, a portion having a low stretchability, a portion having a higher breathability and a higher stretchability than the stretchable base fabric, It has a portion having lower air permeability and lower stretchability than the stretchable base fabric. In addition, the resin-processed portion where the air permeability is low and the stretchability is low, when the obtained fabric is used as a garment, the air-permeability is lower than the portion where the non-exhaust portion is not subjected to resin processing, and the pressure is reduced. Since it becomes high, it becomes a garment in which a multi-stage air permeability difference and a pressure difference are partially produced.

以下、実施例により本発明を具体的に説明する。なお、本発明において、布帛のストレッチ性の評価、布帛強度等の測定は、以下の方法によった。   Hereinafter, the present invention will be described specifically by way of examples. In the present invention, the evaluation of the stretchability of the fabric, the measurement of the fabric strength, and the like were based on the following methods.

なお加工布帛や製品からの試験片のサンプリングに対して、高通気度部位とは、測定に用いる試料部位全てが抜蝕加工されている部位はもちろんであるが、伸縮性レベルのコントロール及び意匠性をも得る為に抜蝕処理部と非抜蝕部を例えば小花やドットのような小柄が分散せしめた部位も含み、低通気度部位とは、測定に用いる試料部位全てが抜蝕加工されていない部位はもちろんであるが、製品から測定試料を得る場合、試料として得られる全面非抜蝕部位が無い場合、最も抜蝕加工処理された場所が少ない部位を非抜蝕部として測定に用いることとする。この場合、目安として試料の80%以上、更に好ましくは90%以上の面積で非抜蝕部である基布部が存在する事が望ましい。またベース基布に対して抜蝕加工のみならず更に樹脂プリントが付与された製品の場合、前記樹脂プリント部を含む部分を低通気度部とする。   For sampling of test pieces from processed fabrics and products, the high air permeability part is not only the part where all the sample parts used for measurement are removed, but the control of the stretch level and the design. In order to obtain a low-air permeability part, the part of the sample used for measurement is also subjected to the removal process. Of course, there is no part, but when obtaining a measurement sample from the product, if there is no whole non-exhausted part obtained as a sample, use the part with the fewest areas that have been subjected to the removal process as the non-exhaust part And In this case, as a guideline, it is desirable that a base fabric portion which is a non-exhaust portion exists in an area of 80% or more, more preferably 90% or more of the sample. In addition, in the case of a product in which not only a discharge process but also a resin print is applied to the base fabric, a portion including the resin print portion is set as a low air permeability portion.

(通気度)
布帛を25℃、湿度65%条件の環境可変室で12時間調整し、JIS L1018一般試験方法(フラジール形試験)に従って、テクステスト社製、通気度試験機FX3300で測定をおこない、通気度(cm3/cm2/sec)を求めた。
(Air permeability)
The fabric was adjusted for 12 hours in an environment variable room at 25 ° C. and a humidity of 65%, and measured according to JIS L1018 general test method (fragile type test) with Tex Test Corp., air permeability tester FX3300, and the air permeability (cm 3 / Cm2 / sec).

(15%伸長時の通気性)
布帛を経かつ緯方向に15%伸長させた状態で、木枠に固定し、通気性評価の方法で通気度を求めた。
(Breathability at 15% elongation)
The fabric was warped and stretched 15% in the weft direction, fixed to a wooden frame, and the air permeability was determined by a method for evaluating air permeability.

(伸長率、伸長率比)
本発明における伸長率は、測定に用いる試料を準備するため、巾3cm×長さ6cmのカット反を経緯方向にそれぞれ3枚ずつ採取し、繊維方向の目を揃え巾2.5cmに調整して測定試料とする。この試料を定速伸長引張り試験機につかみ間隔3cmとしてつかみ具で滑らないように固定する。1分間当たりつかみ間隔の100%の3cm/分引張り速度で荷重伸長曲線を描かせ、14.7N(1.5kgf)時の伸長率Eを次式で求める。
(Elongation rate, Ratio of elongation rate)
In order to prepare a sample used for measurement, the elongation rate in the present invention was obtained by collecting 3 sheets each of cuts of 3 cm in width × 6 cm in length in the weft direction, aligning the eyes in the fiber direction and adjusting the width to 2.5 cm. A measurement sample is used. This sample is fixed to a constant speed extension tensile tester so that it does not slide with a gripper with a grip interval of 3 cm. A load elongation curve is drawn at a tensile rate of 3 cm / min, which is 100% of the grip interval per minute, and an elongation rate E at 14.7 N (1.5 kgf) is obtained by the following equation.

伸長率E(%)=[(L1−L0)/L0]×100
L0:元の試料の長さ(3cm)
L1:14.7N(1.5kgf)時の試料の長さ(cm)
伸長率比は、布帛の経及び緯方向について抜蝕加工による抜蝕部と非抜蝕部のそれぞれの部分の伸長率を測定し、同方向での抜蝕部の伸長率と非抜蝕部の伸長率の比率を求める。
Elongation rate E (%) = [(L1-L0) / L0] × 100
L0: Length of original sample (3 cm)
L1: Length of sample (cm) at 14.7 N (1.5 kgf)
Elongation rate ratio is determined by measuring the elongation rate of each part of the unextracted part and the non-extracted part by the removal process in the warp and weft directions of the fabric. The ratio of the elongation rate is obtained.

伸長率比(倍)=抜蝕部伸長率(%)/非抜蝕部伸長率(%)
(30%伸長時応力、30%伸長時応力比)
30%伸長時応力は、前記の伸長率の測定時に、30%伸長したときに測定した応力(cN/gf)であり、荷重伸長曲線からも読み取れる。30%伸長時応力は、伸びた際の抵抗を示すもので、着用時を想定した30%伸びた状態での身体に対する締め付け感を表す指標である。同じ伸長率にあって、応力が異なると身体に対する圧迫感が異なり、低応力では低圧迫感、高応力では高圧迫感を呈する。
Elongation rate ratio (times) = Elongation portion elongation rate (%) / Non-extraction portion elongation rate (%)
(30% elongation stress, 30% elongation stress ratio)
The stress at 30% elongation is the stress (cN / gf) measured when the elongation rate is measured at the time of 30% elongation, and can be read from the load elongation curve. The stress at the time of 30% elongation indicates the resistance when stretched, and is an index that represents a feeling of tightening with respect to the body in a stretched state by 30% assuming wearing. At the same elongation rate, when the stress is different, the feeling of pressure on the body is different. At low stress, the feeling of pressure is low, and at high stress, the pressure is high.

30%伸長時応力比は、同方向での抜蝕部の30%伸長時応力と非抜蝕部の30%伸長時応力の比率を求める。 The 30% elongation stress ratio is the ratio of the 30% elongation stress of the extracted portion and the 30% elongation stress of the non-extracted portion in the same direction.

30%伸長時応力比(倍)=抜蝕部30%伸長時応力(cN/gf)/非抜蝕部30%伸長時応力(cN/gf)
この30%伸長時応力比が小さいことは、ストレッチ性の差が大きくなり、圧迫感にも差が付与することができることを意味する。
Stress ratio at 30% elongation (times) = 30% stress at elongation (cN / gf) / 30% elongation at non-excavated portion (cN / gf)
The small stress ratio at 30% elongation means that the difference in stretchability is large and that a difference can be imparted to the feeling of pressure.

(Comparative Example 2)
Instead of using 66 nylon 44 dtex 20 filament, which is a non-extractable fiber having no stretch property, modified with a third component having an alkali metal sulfonic acid group, which is the same extractable fiber as in Example 1, in place of the tissue. A raschel knitted fabric as a base fabric was obtained in the same manner as in Example 1 except that the untwisted yarn of the polyester fiber 33 dtex 36 filament was used. This woven or knitted fabric had a course of 45 pcs, a well of 50 pcs, and a basis weight of 250 g / m2.

前記織編物に実施例1と同様抜蝕加工を施し、比較例の伸縮性差を有する織編物を得た。この比較例の部分的に得られたラッセル編地の通気度は、測定部位全面が抜蝕加工した部位に於いて通気度200(cm3/cm2/sec)、全面非抜蝕部位の通気度45(cm3/cm2/sec)、小花のモチーフ部位の通気度100(cm3/cm2/sec)であった。抜蝕部である高通気度部位の通気度が非抜蝕部である低通気度部位の通気度の比率は4.4倍であった。   The woven or knitted fabric was subjected to a discharging process in the same manner as in Example 1 to obtain a woven or knitted fabric having a difference in stretchability of the comparative example. The air permeability of a partially obtained raschel knitted fabric of this comparative example is as follows: air permeability of 200 (cm 3 / cm 2 / sec) at the site where the entire measurement site was removed, and air permeability of 45 at the entire non-exhausted site. The air permeability of the floret motif site was 100 (cm3 / cm2 / sec). The ratio of the air permeability of the low air permeability portion where the air permeability of the high air permeability portion which is the extracted portion is non-exhausted portion was 4.4 times.

伸縮性は、測定部位全面が抜蝕加工した部位の伸長率は経210%×緯350%、30%伸長時応力は、経40cN/gf×緯20cN/gfであり、全面非抜蝕部位の伸長率は経160%×緯60%、30%伸長時応力は、経140cN/gf×緯250cN/gfであった。伸長率の比率は緯5.8であり、30%伸長時応力の比率は緯0.08であった。   The stretchability is 210% x 350% latitude and 30% elongation at the site where the entire surface of the measurement site was etched, and the stress at the time of elongation is 40 cN / gf x 20 cN / gf.

この部分的に伸縮性を有するラッセル編地を裁断し、一例としてガードルを得た。製品には所定部位に通気度、着圧に差があるものの、抜蝕部分はストレッチ性を有する非抜蝕性繊維のみであることから、伸縮性が非常に高すぎ、30%伸長時応力も低い為、部分的にサポート感の少ない、望ましい着圧差を有した製品にはならなかった。   This partially stretchable raschel knitted fabric was cut to obtain a girdle as an example. Although there is a difference in air permeability and pressure at the specified part of the product, the part to be removed is only non-extractable fiber with stretchability, so the stretchability is very high and the stress at 30% elongation is also Because it was low, it did not become a product with a desired pressure difference, with a partial feeling of support.

The area ratio of the resin processed portion was set to about 15% of the remaining portion of the base base fabric that is a non-exhaust portion. In addition to the polyurethane fiber, the polyethylene terephthalate at the core of the extractable fiber a remains as a fine fiber (corresponding to the non-extractable fiber c) of about 20 dtex / 24 f in the extracted portion of the knitted fabric obtained. The fine fibers contributed to maintaining strength and controlling stretchability at the extracted portion in an inconspicuous state.
