【発明の属する技術分野】
本発明はポリトリメチレンテレフタレート繊維を用いた裏地に関するものであって、風合いが柔軟で、且つ縫製時の取り扱い性に優れたポリエステル系100%裏地に関するものである。
【0002】
【従来の技術】
従来、ポリエチレンテレフタレート繊維100%からなる裏地は、再生セルロース繊維100%からなる裏地に比べて、安価で、引っ張り・屈曲・摩耗に対する強度も強く、且つ洗濯による寸法安定性に優れ、外観変化の少ない特性を有しているという理由で衣服の裏地の代表素材として普及している。特に、婦人用途に於いては、軽くて薄く柔軟な平織物裏地が最も普及している。
一方、婦人用途の表地は、素材の多様な組み合わせや染色仕上げ加工機の発展、加工方法の改良に伴って風合を非常に柔軟化した表地が流行となっている。
【0003】
そのようなファッション動向の中で、ポリエチレンテレフタレート繊維100%の裏地についても表地と同様に、風合いを柔軟化した裏地が高級裏地として定着してきている。風合い柔軟化の手法としては、織物設計密度ダウン、経緯糸に使用するマルチフィラメント単糸の細デニール化、染色仕上げ加工時に高濃度の苛性ソーダ液を用いて繊維を減量加工する方法が採られているが、中でも減量加工によって風合いを柔軟化した商品が殆どである。
【0004】
減量加工を施した商品の中でも特に減量率が10〜15%程度の高減量商品は、非常に柔軟で価格も高く高級差別化裏地として用いられている。
減量加工による風合い柔軟化の機構は、ポリエチレンテレフタレート繊維表面を高濃度苛性ソーダ液によって加水分解し繊維を細化する事によって起こるが、同時に織物を構成する経糸と緯糸間に隙間が形成され、又経緯糸を構成するマルチフィラメント間にも隙間が出来ることにより達成出来る。
【0005】
しかし、高減量加工を施したこの様な裏地は、風合いが柔軟である反面経糸と緯糸間に隙間が形成されている為、小さな応力で動き易い性質を持っている。
この動きやすい性質は、曲げ剛性及びせん断剛性として定量化できるが、減量加工による風合い柔軟化は、上記機構より必然的に曲げ剛性とせん断剛性の低下が起こる。
この様に小さな応力で動き易い性質は、衣服を工業的規模で生産する場合に問題となって来ている。
【0006】
具体的には、縫製準備工程での延反・裁断時に裏地がせん断方向に変形しやすいと、延反時に地の目がずれたり、重ねた時両耳部が整然と揃わなかったりするため、作業効率が非常に悪く人手をかけて、低速で慎重な作業を余儀なくされている。この延反・裁断工程は出来上がりの衣服の品質を左右する最も重要な工程であり特に注意を必要とする作業になる。
延反後の裁断に於いてもナイフ切断時、裏地が変形しやすいため裁断不良を引き起こすという問題も有している。パーツ縫製の段階においてもパーツとパーツを縫い合わせる時、パーツの端部同士を揃えるのに時間を要しているのが現状である。
【0007】
【発明が解決しようとする課題】
すなわち本発明の目的は、ポリエステル系繊維100%からなる裏地の利点、引っ張り・摩耗・屈強等にたいする強さ及び洗濯による寸法安定性等の裏地機能を有し、かつ上述した縫製時の取り扱い性を著しく改善し得る風合いの柔軟なポリエステル系繊維100%より成る裏地を提供することである。
【0008】
【課題を解決するための手段】
本発明者らは、上記の課題について種々検討した結果、裏地を構成する経糸及び/又は緯糸としてポリトリメチレンテレフタレート繊維を用い、且つ裏地の曲げ剛性とせん断剛性をある範囲にした裏地が縫製時の取り扱い性を著しく改善し、且つ柔軟な表地のシルエットを阻害しない裏地となる事を見出し、本発明を完成するに至った。特に、縫製時の取り扱い性を向上させるため、本発明者らはせん断剛性Gとの関係について実験を重ねた結果Gが0.35以下の場合延反性が悪くなる事をつきとめると同時に、柔軟な風合いを満足する為にはGが0.45以下で且つ曲げ剛性がある一定範囲にある必要があることを突き止めた。
すなわち本発明は、経糸及び/又は緯糸がポリトリメチレンテレフタレート繊維で構成された平織物裏地であって、KES−FBによる曲げ剛性Bが0.01〜0.03gf・ cm2 /cmで、且つせん断剛性Gが0.35〜0.45gf/cm・deg.の範囲である事を特徴とする裏地である。
【0009】
以下本発明について詳述する。
本発明で用いるポリトリメチレンテレフタレート繊維とは、トリメチレンテレフタレート単位を主たる繰り返し単位とするポリエステル繊維をいい、トリメチレンテレフタレート単位を約50モル%以上、好ましくは70モル%以上、さらには80モル%以上、さらに好ましくは90モル%以上のものをいう。したがって、第三成分として他の酸成分及び/又はグリコール成分の合計量が約50モル%以下、好ましくは30モル%以下、さらには20モル%以下、さらに好ましくは10モル%以下の範囲で含有されたポリトリメチレンテレフタレートを包含する。
【0010】
ポリトリメチレンテレフタレートは、テレフタル酸又はその機能的誘導体と、トリメチレングリコール又はその機能的誘導体とを、触媒の存在下で、適当な反応条件下に縮合せしめることにより合成される。この合成過程において、適当な一種又は二種以上の第三成分を添加して共重合ポリエステルとしてもよいし、又、ポリエチレンテレフタレート等のポリトリメチレンテレフタレート以外のポリエステルとポリトリメチレンテレフタレートを別個に合成した後、ブレンドしたり、複合紡糸(鞘芯、サイドバイサイド等)してもよい。
【0011】
添加する第三成分としては、脂肪族ジカルボン酸(シュウ酸、アジピン酸等)、脂環族ジカルボン酸(シクロヘキサンジカルボン酸等)、芳香族ジカルボン酸(イソフタル酸、ソジウムスルホイソフタル酸等)、脂肪族グリコール(エチレングリコール、1,2−プロピレングリコール、テトラメチレングリコール等)、脂環族グリコール(シクロヘキサンジメタノール等)、芳香族を含む脂肪族グリコール(1,4−ビス(β−ヒドロキシエトキシ)ベンゼン等)、ポリエーテルグリコール(ポリエチレングリコール、ポリプロピレングリコール等)、脂肪族オキシカルボン酸(ω−オキシカプロン酸等)、芳香族オキシカルボン酸(P−オキシ安息香酸等)等が挙げられる。又、1個又は3個以上のエステル形成性官能基を有する化合物(安息香酸等又はグリセリン等)も重合体が実質的に線状である範囲内で使用出来る。
【0012】
さらに二酸化チタン等の艶消剤、リン酸等の安定剤、ヒドロキシベンゾフェノン誘導体等の紫外線吸収剤、タルク等の結晶化核剤、アエロジル等の易滑剤、ヒンダードフェノール誘導体等の抗酸化剤、難燃剤、制電剤、顔料、蛍光増白剤、赤外線吸収剤、消泡剤等が含有されていてもよい。
本発明におけるポリトリメチレンテレフタレート繊維の紡糸については、1500m/分程度の巻取り速度で未延伸糸を得た後、2〜3.5倍程度で延撚する方法、紡糸−延撚工程を直結した直延法(スピンドロー法)、巻取り速度5000m/分以上の高速紡糸法(スピンテイクアップ法)などの何れを採用しても良い。
【0013】
又、繊維の形態は、長繊維でも短繊維でもよいが裏地機能としての重要な滑り性を満足する為には、マルチフィラメントであることが好ましい。繊維の太さ、断面形状については特に制限されることはなく、長さ方向に均一なものや太細のあるものでもよく、断面においても丸型、三角、L型、T型、Y型、W型、八葉型、偏平、ドッグボーン型等の多角形型、多葉型、中空型や不定形なものでもよい。
【0014】
一般的に裏地として用いられる繊維のトータルデニールは50〜100d、好ましくは50〜75dの範囲であり、単糸デニールでは0.5〜5d、好ましくは1〜3dの範囲である。
さらに糸条の形態としては、マルチフィラメント原糸(極細糸を含む)、甘撚糸〜強撚糸、混繊糸、仮撚糸(POYの延伸仮撚糸を含む)、いわゆるタスラン加工糸等の流体噴射加工糸等があるが、マルチフィラメント原糸を用いる事が本発明に於いては好ましい。
【0015】
経糸及び/又は緯糸がポリトリメチレンテレフタレート繊維で構成されてなる平織物裏地とは次のものをいう。
ケース1:経糸および緯糸ともポリトリメチレンテレフタレート繊維を用いる場合。
ケース2:経糸にポリトリメチレンテレフタレート繊維を用い、緯糸にポリエチレンテレフタレート繊維を用いる場合。
ケース3:経糸にポリエチレンテレフタレート繊維を用い、緯糸にポリトリメチレンテレフタレート繊維を用いる場合。
ケース4:経糸にポリトリメチレンテレフタレート繊維を用い、緯糸にポリブチレンテレフタレート繊維を用いる場合。
ケース5:経糸にポリブチレンテレフタレート繊維を用い、緯糸にポリトリメチレンテレフタレート繊維を用いる場合。
【0016】
ここで、曲げ剛性Bとせん断剛性Gとは、KES−FB計測システム(Kawabata's Evaluation System for Fabric )によって測定される値のことである。KES−FB計測システムは布帛の風合いに影響を与える力学的特性を4機種(引張り・せん断、純曲げ、圧縮、表面特性)を用いて計測できるシステムになっている。
【0017】
曲げ剛性B、せん断剛性Gともカトーテック(株)製、KES−FB1(引張り・せん断試験機)、KES−FB2(純曲げ試験機)を用いて下記測定条件にて測定する事によって得られる経方向と緯方向の平均値を言う。
【0018】
ケース1〜5の裏地において、ケース1の裏地の場合は高濃度の苛性ソーダ液を用いての減量加工を施す事なしに、本発明の曲げ剛性Bが0.01〜0.03gf・ cm2 /cmで、且つせん断剛性Gが0.35〜0.45gf/cm・deg.の範囲の裏地を得る事が出来る。
ケース2〜5の裏地の場合は、織物の重量を基準として、2〜5%程度の減量率で減量するとBとGが本発明の範囲のものとなる。これはケース2〜3の場合ポリエチレンテレフタレート繊維がポリトリメチレンテレフタレート繊維よりも減量され易い為、5%を越える減量率では、ポリエチレンテレフタレート繊維の減量率が大きくなる為、織物組織交点の隙間が大きくなりせん断剛性が本発明の範囲をはずれ、せん断方向に変形しやすい裏地となってしまう。
【0019】
又、ケース4〜5の場合も、ポリブチレンテレフタレート繊維がポリトリメチレンテレフタレート繊維よりも減量され易い為、5%を越える減量率では、ポリブチレンテレフタレート繊維の減量率が大きくなる為、織物組織交点の隙間が大きくなりせん断剛性が本発明の範囲をはずれ、せん断方向に変形しやすい裏地となってしまう。
ケース1〜5の裏地において制電性を向上させる目的で経糸又は緯糸に制電剤を含有した制電糸を用いる事が、裏地機能を満足させる為にも好ましい。

以上詳述した様に本発明の裏地は、風合いが柔軟で、且つ縫製時の取り扱い性を著しく改善し得るポリエステル系繊維100%より成る裏地を提供することが出来る。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a backing using a polytrimethylene terephthalate fiber, and relates to a polyester-based 100% backing that has a soft texture and excellent handling properties during sewing.
[0002]
[Prior art]
Conventionally, a lining made of 100% polyethylene terephthalate fiber is less expensive than lining made of 100% regenerated cellulose fiber, has high strength against tension, bending, and abrasion, has excellent dimensional stability by washing, and has little change in appearance. It is popular as a representative material for clothing lining because of its characteristics. In particular, for women's use, a light, thin and flexible plain fabric lining is most popular.
On the other hand, dressing materials for women are becoming popular with various combinations of materials, the development of dyeing and finishing machines, and improved processing methods.
[0003]
In such fashion trends, as for the lining of 100% polyethylene terephthalate fiber, the lining with a softened texture has become established as a high-quality lining. As a method for softening the texture, a method is adopted in which the design density of the fabric is reduced, the multifilament single yarn used for the warp and weft is finely denier, and the fiber is processed with a high concentration of caustic soda at the time of dyeing finishing. However, most of the products have a softened texture by weight reduction.
[0004]
Among the products subjected to weight loss processing, particularly high weight loss products having a weight loss rate of about 10 to 15% are used as a high-class differentiation lining because they are very flexible and expensive.
The mechanism of softening the texture by weight reduction processing occurs by hydrolyzing the polyethylene terephthalate fiber surface with high-concentration caustic soda solution and thinning the fiber, but at the same time a gap is formed between the warp and weft constituting the fabric, and the weft This can be achieved by forming a gap between the multifilaments constituting the yarn.
[0005]
However, such a lining which has been subjected to high weight reduction processing has a soft texture, but has a property of being easily moved with a small stress because a gap is formed between the warp and the weft.
This easy-to-move property can be quantified as bending stiffness and shear stiffness, but softening of the texture by weight reduction processing inevitably results in lower bending stiffness and shear stiffness than the above mechanism.
Such a property of being easily moved by a small stress has become a problem when clothes are produced on an industrial scale.
[0006]
Specifically, if the lining is easily deformed in the shearing direction at the time of stretching or cutting in the sewing preparation process, the ground will be displaced at the time of stretching, or both ears may not be orderly aligned when stacked. It is very inefficient and manpowered to be slow and careful. This spreading / cutting process is the most important process that influences the quality of the finished clothes, and requires special attention.
Even in the cutting after spreading, there is also a problem that the lining is easily deformed when the knife is cut, causing a cutting failure. Even at the part sewing stage, when sewing parts together, it takes time to align the ends of the parts.
[0007]
[Problems to be solved by the invention]
That is, the object of the present invention is to provide the lining function such as the advantage of the lining made of 100% polyester fiber, the strength against tensile, abrasion, and bending strength and the dimensional stability by washing, and the above-described handling at the time of sewing. It is to provide a backing made of 100% flexible polyester fiber with a texture that can be significantly improved.
[0008]
[Means for Solving the Problems]
As a result of various studies on the above problems, the present inventors have used polytrimethylene terephthalate fibers as warps and / or wefts constituting the lining, and a lining having a bending rigidity and shear rigidity of the lining within a certain range is sewn. As a result, the present invention has been completed. In particular, in order to improve the handleability at the time of sewing, the present inventors have conducted experiments on the relationship with the shear rigidity G. As a result, when G is 0.35 or less, it has been found that the rebound property deteriorates, and at the same time, the flexibility In order to satisfy the desired texture, it was found that G must be 0.45 or less and the bending rigidity must be within a certain range.
That is, the present invention is a plain fabric lining in which the warp and / or the weft is composed of polytrimethylene terephthalate fiber, the flexural rigidity B by KES-FB is 0.01 to 0.03 gf · cm 2 / cm, and Shear rigidity G is 0.35-0.45 gf / cm · deg. The lining is characterized by being in the range.
[0009]
The present invention is described in detail below.
The polytrimethylene terephthalate fiber used in the present invention refers to a polyester fiber having a trimethylene terephthalate unit as a main repeating unit. The trimethylene terephthalate unit is about 50 mol% or more, preferably 70 mol% or more, and more preferably 80 mol%. More preferably, it is 90 mol% or more. Therefore, the total amount of the other acid component and / or glycol component as the third component is about 50 mol% or less, preferably 30 mol% or less, more preferably 20 mol% or less, more preferably 10 mol% or less. Polytrimethylene terephthalate prepared.
[0010]
Polytrimethylene terephthalate is synthesized by condensing terephthalic acid or a functional derivative thereof with trimethylene glycol or a functional derivative thereof in the presence of a catalyst under suitable reaction conditions. In this synthesis process, it may be used as the appropriate one or more additives to the copolyester a third component, also separately polytrimethylene terephthalate other polyester Le polytrimethylene terephthalate such as polyethylene terephthalate After synthesis, they may be blended or compositely spun (sheath core, side-by-side, etc.).
[0011]
The third component to be added includes aliphatic dicarboxylic acids (oxalic acid, adipic acid, etc.), alicyclic dicarboxylic acids (cyclohexanedicarboxylic acid, etc.), aromatic dicarboxylic acids (isophthalic acid, sodium sulfoisophthalic acid, etc.), fat Aliphatic glycols (ethylene glycol, 1,2-propylene glycol, tetramethylene glycol, etc.), alicyclic glycols (cyclohexanedimethanol, etc.), aliphatic glycols containing aromatics (1,4-bis (β-hydroxyethoxy) benzene Etc.), polyether glycol (polyethylene glycol, polypropylene glycol etc.), aliphatic oxycarboxylic acid (ω-oxycaproic acid etc.), aromatic oxycarboxylic acid (P-oxybenzoic acid etc.) and the like. A compound having one or three or more ester-forming functional groups (such as benzoic acid or glycerin) can also be used within the range where the polymer is substantially linear.
[0012]
In addition, matting agents such as titanium dioxide, stabilizers such as phosphoric acid, ultraviolet absorbers such as hydroxybenzophenone derivatives, crystallization nucleating agents such as talc, easy lubricants such as aerosil, antioxidants such as hindered phenol derivatives, difficulty A flame retardant, antistatic agent, pigment, fluorescent whitening agent, infrared absorber, antifoaming agent, and the like may be contained.
Regarding the spinning of polytrimethylene terephthalate fiber in the present invention, after obtaining an undrawn yarn at a take-up speed of about 1500 m / min, a method of drawing about 2 to 3.5 times, and a spinning-twisting step are directly connected. Any of the straight rolling method (spin draw method), a high-speed spinning method (spin take-up method) with a winding speed of 5000 m / min or more, and the like may be employed.
[0013]
The fiber may be either a long fiber or a short fiber, but a multifilament is preferable in order to satisfy important slipperiness as a backing function. The thickness and cross-sectional shape of the fiber are not particularly limited, and may be uniform or thick in the length direction. Also in the cross section, round, triangular, L-shaped, T-shaped, Y-shaped, It may be a polygonal type such as a W type, an eight-leaf type, a flat shape, or a dogbone type, a multi-leaf type, a hollow type, or an indeterminate type.
[0014]
Generally, the total denier of fibers used as a backing is in the range of 50 to 100d, preferably 50 to 75d, and in the case of single yarn denier, it is in the range of 0.5 to 5d, preferably 1 to 3d.
Furthermore, as the form of the yarn, fluid injection processing such as multifilament raw yarn (including extra fine yarn), sweet twisted yarn to strong twisted yarn, mixed yarn, false twisted yarn (including POY drawn false twisted yarn), so-called taslan processed yarn, etc. Although there are yarns and the like, it is preferable in the present invention to use a multifilament yarn.
[0015]
The plain fabric lining in which the warp and / or the weft is composed of polytrimethylene terephthalate fibers refers to the following.
Case 1: When using polytrimethylene terephthalate fiber for both warp and weft.
Case 2: When polytrimethylene terephthalate fiber is used for the warp and polyethylene terephthalate fiber is used for the weft.
Case 3: When polyethylene terephthalate fiber is used for the warp and polytrimethylene terephthalate fiber is used for the weft.
Case 4: When polytrimethylene terephthalate fiber is used for the warp and polybutylene terephthalate fiber is used for the weft.
Case 5: When polybutylene terephthalate fiber is used for the warp and polytrimethylene terephthalate fiber is used for the weft.
[0016]
Here, the bending stiffness B and the shear stiffness G are values measured by a KES-FB measurement system (Kawabata's Evaluation System for Fabric). The KES-FB measurement system is a system that can measure the mechanical characteristics that affect the texture of the fabric using four types (tensile / shear, pure bending, compression, surface characteristics).
[0017]
Both bending stiffness B and shear stiffness G are obtained by measuring under the following measurement conditions using KES-FB1 (tensile / shear tester), KES-FB2 (pure bending tester) manufactured by Kato Tech Co., Ltd. The average value of direction and latitude.
[0018]
In the case 1-5 lining, in the case 1 case lining, the bending rigidity B of the present invention is 0.01-0.03 gf · cm 2 / cm without performing weight reduction using high-concentration caustic soda solution. cm and the shear rigidity G is 0.35 to 0.45 gf / cm · deg. The lining of the range can be obtained.
In the case of the linings of cases 2 to 5, B and G fall within the scope of the present invention when the weight is reduced at a weight loss rate of about 2 to 5% based on the weight of the fabric. This is because in cases 2 to 3, polyethylene terephthalate fibers are more easily reduced than polytrimethylene terephthalate fibers. Therefore, when the weight loss rate exceeds 5%, the weight loss rate of polyethylene terephthalate fibers increases, and the gap between the fabric tissue intersections is large. Therefore, the shear rigidity is out of the range of the present invention, and it becomes a lining which is easily deformed in the shear direction.
[0019]
Also in cases 4 to 5, since the polybutylene terephthalate fiber is more easily reduced than the polytrimethylene terephthalate fiber, the weight loss rate exceeding 5% increases the weight loss rate of the polybutylene terephthalate fiber. The gap becomes larger and the shear rigidity is out of the range of the present invention, so that it becomes a lining which is easily deformed in the shear direction.
In order to improve antistatic properties in the lining of cases 1 to 5, it is preferable to use antistatic yarns containing an antistatic agent in the warp or weft to satisfy the lining function.
The density of the warp and weft of the plain woven fabric lining of the present invention is 90 to 130 yarns / 吋 in the case of a warp fineness of 50 to 75 denier, and the weft density of 70 to 70 in the case of a weft fineness of 50 to 75 denier. What is necessary is just to set according to the cases 1-5 of the said thread | yarn combination, or the kind of use in the range of 110 pieces / 吋.
[0020]
The method for dyeing and finishing the lining of the present invention is not particularly limited, and the lining of cases 1 to 5 is not different from the lining processing method using a conventional polyethylene terephthalate fiber. A general dyeing finishing process is a process of scouring desizing, presetting, alkali weight reduction processing, dyeing and finishing.
The alkali weight reduction process is not different from the conventionally used method, and it is sufficient that the weight loss rate in the fabric weight can be controlled to 2 to 5%. As the alkali weight reduction processing method, any of batch method (suspension method, liquid flow method, etc.), continuous method (pad steam method, pad dry method, etc.), and semi-continuous method (pad roll method, etc.) may be used. .
[0021]
