Description
本発明は、耐摩耗性に優れた資材用布帛材料に関するものである。さらに詳しくは、本発明は、ポリエステル繊維を主たる構成成分とする織物を含み、耐摩耗性に優れ、カーシート、カバン地等のような資材用途に適した布帛材料に関するものである。 The present invention relates to a fabric material for materials having excellent wear resistance. More specifically, the present invention relates to a fabric material that includes a woven fabric mainly composed of polyester fiber, has excellent wear resistance, and is suitable for material use such as car seats and bags.
ポリエステル繊維を用いて得られる布帛材料は、耐候性および寸法安定性などにおいて満足できるものであるが耐摩耗性においては未だ不十分であるため、この点における改善が望まれている。
例えば製糸方法を工夫して寸法安定性と耐疲労性を向上させたものが提示されている(特許文献１)。しかしこういった製法で得られた糸は繊維軸方向の強度は高いが、繊維軸と直交する方向など他の方向からの外力には弱く、衣料用などに想定される全方向から摩耗が生じる場合には十分な耐摩耗性を得ることができない。
Fabric materials obtained using polyester fibers are satisfactory in terms of weather resistance, dimensional stability, etc., but are still insufficient in wear resistance, and improvements in this respect are desired.
For example, a device in which the dimensional stability and fatigue resistance are improved by devising the yarn production method has been proposed (Patent Document 1). However, although the yarn obtained by such a manufacturing method has high strength in the fiber axis direction, it is weak against external forces from other directions such as the direction orthogonal to the fiber axis, and wear occurs from all directions assumed for clothing. In some cases, sufficient wear resistance cannot be obtained.
また、耐摩耗性が良好な衣料用織物として、ポリエステルの繊度や極限粘度を規定したものが提示されている(特許文献２)。ここでは配向度や結晶化度が好ましい範囲として規定されているが、それだけではより過酷な状況が連続的に発生しうる産業資材における耐摩耗性には不十分である。
さらに、繊維引張り時の特定伸度範囲の荷伸曲線を規定し耐摩耗性を向上させるという繊維が提示されている(特許文献３)。これにより繊維を摩耗させるような外力に対しある程度の衝撃吸収能が発現される可能性はあるが、これも繊維軸方向に対する改良であり、繊維軸と直行する方向など他の方向からの外力には何ら考慮されておらず不十分である。
Moreover, what prescribed | regulated the fineness and intrinsic viscosity of polyester as a textile fabric for clothing with favorable abrasion resistance is proposed (patent document 2). Here, the degree of orientation and the degree of crystallinity are defined as preferred ranges, but that alone is insufficient for the wear resistance in industrial materials where severer situations can continuously occur.
Furthermore, a fiber has been proposed that improves the wear resistance by defining a load elongation curve in a specific elongation range during fiber tension (Patent Document 3). As a result, there is a possibility that a certain amount of shock absorbing ability can be developed for external forces that wear the fiber, but this is also an improvement to the fiber axis direction, and external forces from other directions, such as the direction perpendicular to the fiber axis. Is not considered at all.
本発明の目的は、上記従来技術を背景になされたもので、その目的は、布帛とした際に耐摩耗性に優れ、カーシートおよびカバン地等に最適な布帛材料を提供することにある。 The object of the present invention is to provide a fabric material that is excellent in abrasion resistance when used as a fabric and is optimal for car seats, bags and the like.
本発明者らは、上記の課題を解決するために鋭意検討した結果、特に、ポリエステル繊維の繊度、強度、配向度を特定範囲に制御することにより、上記目的が達成できることを究明し、本発明に到達した。 As a result of intensive studies to solve the above-mentioned problems, the present inventors have determined that the above-mentioned object can be achieved by controlling the fineness, strength, and orientation degree of the polyester fiber within a specific range, and the present invention.

以下、本発明の実施形態について詳細に説明する。
本発明の耐摩耗性に優れる資材用布帛材料は、ポリエステル繊維を主たる構成成分として含む織編物を用いて構成されている。
本発明の布帛材料用織編物におけるポリエステル繊維の含有量は、布帛全重量に対し、６０〜１００％であることが好ましく、８０〜１００重量％であることがより好ましい。ポリエステル繊維の含有量が６０重量％未満である場合、得られる布帛材料は、耐磨耗性、耐破れ性、寸法安定性などにおいて不十分になることがある。
Hereinafter, embodiments of the present invention will be described in detail.

The polyester fiber content in the woven or knitted fabric for fabric material of the present invention is preferably 60 to 100%, more preferably 80 to 100% by weight, based on the total weight of the fabric. When the content of the polyester fiber is less than 60% by weight, the obtained fabric material may be insufficient in abrasion resistance, tear resistance, dimensional stability, and the like.
本発明に用いられるポリエステルは、分子鎖中に９０モル％以上の、好ましくは９５モル％以上のエチレンテレフタレート繰り返し単位を含む重合体であり、なかでもポリエチレンテレフタレートであることが好ましい。本発明に用いられるポリエステルには、１０モル％、好ましくは５モル％未満の、他の繰り返し単位を含んでいてもよく、このような他の繰り返し単位を形成する共重合成分としては、例えばイソフタル酸、ナフタレンジカルボン酸、アジピン酸、オキシ安息香酸、ジエチレングリコール、プロピレングリコール、トリメリット酸、ペンタエリスリトールなどがあげられる。 The polyester used in the present invention is a polymer containing 90 mol% or more, preferably 95 mol% or more of ethylene terephthalate repeating units in the molecular chain, and polyethylene terephthalate is particularly preferable. The polyester used in the present invention may contain 10 mol%, preferably less than 5 mol% of other repeating units. Examples of the copolymer component forming such other repeating units include isophthalic acid. Examples thereof include acid, naphthalenedicarboxylic acid, adipic acid, oxybenzoic acid, diethylene glycol, propylene glycol, trimellitic acid, and pentaerythritol.
また、本発明に用いられるポリエステル繊維には、安定剤、着色剤、制電剤などの添加剤が含まれていても差し支えない。
カーシート、カバン地等の資材用布帛として使用される際の、耐摩耗性、耐破れ性、風合い、軽量性を考慮すると、本発明の布帛材料の目付重量は１００〜１０００ｇ／ｍ２であることが好ましく、より好ましくは２００〜５００ｇ／ｍ２である。
Further, the polyester fiber used in the present invention may contain additives such as a stabilizer, a colorant, and an antistatic agent.
In consideration of wear resistance, tear resistance, texture, and lightness when used as a fabric for materials such as car seats and bags, the fabric weight of the fabric material of the present invention is 100 to 1000 g / m 2 . It is preferably 200 to 500 g / m 2 .
また、本発明の布帛材料のマーチンデール耐摩耗試験は３．５級以上であることが必要であり、好ましくは４．０級以上である。
また、本発明の布帛材料の引裂強力は、１．０ｋｇ（シングルタング法により測定）以上であることが必要であり、それが１．０ｋｇ未満の場合には、当該布帛材料から作られた資材用布帛、例えばカバン地においては使用時に引き裂かれる可能性が高くなる。
Further, the Martindale abrasion resistance test of the fabric material of the present invention needs to be grade 3.5 or higher, preferably grade 4.0 or higher.
In addition, the tear strength of the fabric material of the present invention needs to be 1.0 kg (measured by the single tongue method) or more, and when it is less than 1.0 kg, the material made from the fabric material In fabrics such as bags, there is a high possibility of tearing during use.
本発明の布帛材料は、前記ポリエステル繊維を主成分として含む原糸より構成された織編物を含んでなるものであって、このポリエステル繊維は、下記関係式（１）〜（５）を同時に満足するものであることが肝要である。
（１）０．７≦〔η〕Ｆ≦０．９５
（２）０．５≦ＤＰＦ≦５．０
（３）ＳＴ≧５．０
（４）ＥＬ≧１５
（５）△ｎ≦０．１７５
但し、上記関係式（１）〜（５）において、〔η〕Ｆはポリエステル繊維の固有粘度を表し、ＤＰＦはポリエステル繊維の単繊維繊度（デシテックス）を表し、ＳＴはポリエステル繊維の破断強度（ｃＮ/ｄｔｅｘ）を表し、ＥＬはポリエステル繊維の破断伸度（％）を表し、△ｎはポリエステル繊維の複屈折率を示す。
The fabric material of the present invention comprises a woven or knitted fabric composed of a raw yarn containing the polyester fiber as a main component, and the polyester fiber simultaneously satisfies the following relational expressions (1) to (5). It is important to do it.
(1) 0.7 ≦ [η] F ≦ 0.95
(2) 0.5 ≦ DPF ≦ 5.0
(3) ST ≧ 5.0
(4) EL ≧ 15
(5) Δn ≦ 0.175
However, in the above relational expressions (1) to (5), [η] F represents the intrinsic viscosity of the polyester fiber, DPF represents the single fiber fineness (decitex) of the polyester fiber, and ST represents the breaking strength (cN) of the polyester fiber. / dtex), EL represents the elongation at break (%) of the polyester fiber, and Δn represents the birefringence of the polyester fiber.
すなわち、ポリエステル繊維の固有粘度〔η〕Ｆは、ポリエステル繊維の強伸度特性、タフネス、及び耐摩耗性、耐破れ性に影響を及ぼす重要な要素であり、その範囲は０．７０以上０．９５以下であることが必要であり、好ましくは０．８０以上０．９５以下である。
この〔η〕Ｆが０．７０未満の場合、得られるポリエステル系繊維の破断強伸度は、関係式（６）及び（７）を同時に満足させることが困難になるだけでなく、耐摩耗性も不十分になる。一方〔η〕Ｆが０．９５を越える場合には、製糸性が大きく低下し、糸毛羽、および糸切れ等のない糸条を製造することが難しくなる。
That is, the intrinsic viscosity [η] F of the polyester fiber is an important factor affecting the high elongation property, toughness, abrasion resistance, and tear resistance of the polyester fiber, and its range is 0.70 or more and 0.00. It is necessary to be 95 or less, preferably 0.80 or more and 0.95 or less.
When this [η] F is less than 0.70, the breaking strength and elongation of the resulting polyester fiber not only makes it difficult to satisfy the relational expressions (6) and (7) at the same time, but also wear resistance. Become insufficient. On the other hand, when [η] F exceeds 0.95, the yarn-making property is greatly deteriorated, and it becomes difficult to produce yarns having no yarn fluff or yarn breakage.
本発明に用いられるポリエステル繊維の単繊維繊度ＤＰＦは、０．５〜５．０デシテックスであることが必要である。ＤＰＦが０．５デシテックス未満の場合、この繊維から作られる布帛材料が破断しやすく、かつ摩耗しやすくなるという不都合を生じ、また、ＤＰＦが、５．０デシテックスより大きくなると、この繊維から作られた布帛材料が過度に粗剛になるという不都合を生ずる。 The single fiber fineness DPF of the polyester fiber used in the present invention is required to be 0.5 to 5.0 dtex. If the DPF is less than 0.5 dtex, the fabric material made from this fiber is easily broken and easily worn, and if the DPF is greater than 5.0 dtex, it is made from this fiber. The disadvantage is that the fabric material becomes excessively rough and stiff.
本発明に用いられるポリエステル繊維の破断強伸度はそれぞれ５．０ｃＮ／ｄｔｅｘ以上、および１５％以上であることが必要である。一般的にポリエステル繊維は強度を高くすると伸度が低くなる傾向があるが、強度が５．０ｃＮ／ｄｔｅｘ以上であっても、伸度が１５％未満の場合には、このようなポリエステル繊維含有布帛材料を用いて作られたカーシートやカバン地のような資材用布帛は、脆性が弱く生地が破断しやすくなり、製糸性も悪化する傾向である。また、強度が５．０ｃＮ／ｄｔｅｘ未満の場合、その破断伸度が１５％以上であっても、布帛の引裂強度が弱くなり、耐摩耗性も低くなってしまう。従って、上記関係式（３）および（４）を同時に満足することが好ましく、特に、ＳＴ≧５．５ｃＮ／ｄｔｅｘ、およびＥＬ≧２０％の両関係を同時に満足することがより好ましい。 The breaking strength and elongation of the polyester fiber used in the present invention must be 5.0 cN / dtex or more and 15% or more, respectively. Generally, polyester fibers tend to have low elongation when the strength is increased. However, if the elongation is less than 15% even if the strength is 5.0 cN / dtex or more, such polyester fibers are contained. Fabrics for materials such as car seats and bags made of fabric materials are weak in brittleness, tend to break the fabric, and tend to deteriorate the yarn production. Moreover, when the strength is less than 5.0 cN / dtex, even if the breaking elongation is 15% or more, the tear strength of the fabric is weakened and the wear resistance is also lowered. Therefore, it is preferable that the above relational expressions (3) and (4) are satisfied at the same time, and it is more preferable that both of the relations ST ≧ 5.5 cN / dtex and EL ≧ 20% are satisfied at the same time.
また、高強力の原糸を得るためには、一般的に低紡糸速度で得られた未延伸糸を高倍率で延伸するという技術手段が取られる。この方法により得られた原糸はその非晶部が均一に延伸されているため高い原糸強度を示すが、その原糸の耐熱性は低く、また原糸表面配向が高いため摩耗によりフィブリル化しやすいという欠点を持っている。 In order to obtain a high-strength raw yarn, a technical means is generally used in which an undrawn yarn obtained at a low spinning speed is drawn at a high magnification. The raw yarn obtained by this method shows high raw yarn strength because the amorphous part is uniformly stretched, but the heat resistance of the raw yarn is low and the surface orientation of the raw yarn is high so that it is fibrillated by abrasion. Has the disadvantage of being easy.
一方、高紡糸速度で得られた未延伸糸を延伸することで結晶サイズの大きい繊維構造を得ることができ、原糸の耐熱性を向上させ、原糸表面配向を低くすることで耐フィブリル性を向上させることが知られているが、得られた原糸の強度は低いものとなる。 On the other hand, a fiber structure with a large crystal size can be obtained by drawing an undrawn yarn obtained at a high spinning speed, improving the heat resistance of the raw yarn, and reducing the surface orientation of the raw yarn to prevent fibril resistance. It is known that the strength of the obtained yarn is low.
この原糸の高強度化と対摩耗性向上という相反する性能を両立するために鋭意検討した結果、ポリエステル原糸の配向性の代用特性である△ｎを制御することにより、優れた布帛耐磨耗性と高い布帛引裂強度を両立することのできる資材用布帛に適した原糸を得ることができることを見出した。 As a result of diligent studies to achieve the conflicting performance of increasing the strength of the yarn and improving wear resistance, excellent fabric abrasion resistance is achieved by controlling Δn, which is a substitute property of the orientation of the polyester yarn. It has been found that it is possible to obtain a raw yarn suitable for a material fabric that can achieve both wear and high fabric tear strength.
すなわち、上記関係式（３）および（４）を満たしながらも、関係式（５）を満たすことでそれが可能となる。△ｎが０．１７５を超えると原糸の配向度が高くなるため、その原糸を用いた布帛の磨耗によるフィブリル化が起きやすくなり、また耐熱性も低下し摩耗による融着現象が起きやすくなる。 That is, it is possible to satisfy the relational expression (5) while satisfying the relational expressions (3) and (4). When Δn exceeds 0.175, the degree of orientation of the raw yarn becomes high, so that fibrillation is likely to occur due to wear of the fabric using the raw yarn, and heat resistance is also reduced, so that a fusion phenomenon due to wear is likely to occur. Become.
次に本発明で好ましく用いられるポリエステル繊維を製造するための好ましい方法としては、例えば、固有粘度〔η〕Ｃ＝０．８〜１．０５程度のポリエステルチップを溶融し、口金からポリマーを吐出して溶融押出して紡糸するためにあたり、口金直下の雰囲気を積極加熱したゾーンを用い、このゾーンを経由した繊維状ポリマーメルト流を冷却し、油剤付与した後、得られた未延伸繊維を引取りローラーを経由して巻取り、次いてこれを延伸する方法あるいは前記方法において引取りローラーにより引き取られた繊維を巻き取ることなくただちに延伸する方法などを例示することができる。 Next, as a preferable method for producing the polyester fiber preferably used in the present invention, for example, a polyester chip having an intrinsic viscosity [η] C of about 0.8 to 1.05 is melted, and the polymer is discharged from the die. In order to perform melt extrusion and spinning, a zone in which the atmosphere immediately below the die is positively heated is used. After cooling the fibrous polymer melt flow passing through this zone and applying an oil agent, the resulting undrawn fiber is taken up by a roller. And a method of stretching the fiber and then stretching the fiber, or a method of stretching the fiber immediately after being wound by the take-up roller in the above method.

[Example 1]
Polyethylene terephthalate having an intrinsic viscosity of 0.90 was melted at 300 ° C., the atmosphere temperature under the die was set to 350 ° C., and the molten polymer was discharged. After the discharged yarn is cooled, it is supplied with a spinning oil, a first
The total draw ratio at this time was 1.88 times (the speed of the goded roller 4 / the speed of the hot roller 1), and the overfeed rate was 2% (the speed of the goded roller 4 / the speed of the hot roller 3). A schematic diagram of the yarn making process is shown in FIG.
The obtained polyester had a strength of 5.7 cN / dtex, an elongation of 22%, ηF: 0.80, and Δn: 0.170, and the yarn forming property was also good. The abrasion resistance evaluation and fabric tear strength of the fabric using the obtained polyester filament were good, and a material suitable for the fabric for materials was obtained.

用いる原料ポリマーの固有粘度を変更することで得られた原糸のηＦを表１の通り変更した以外は、実施例１と同様の方法にて８４ｄｔｅｘ／７２フィラメントの原糸を得た。
比較例１ではηＦが低いため、得られた原糸を用いた布帛の耐摩耗性および引裂強力が不十分であった。また、比較例２ではηＦが高すぎるためポリマー吐出部での単糸切れが起こり、製糸性が非常に悪かった。
[Comparative Examples 1 and 2]
An 84 dtex / 72 filament yarn was obtained in the same manner as in Example 1 except that the ηF of the yarn obtained by changing the intrinsic viscosity of the raw material polymer used was changed as shown in Table 1.
In Comparative Example 1, since ηF was low, the wear resistance and tear strength of the fabric using the obtained raw yarn were insufficient. Further, in Comparative Example 2, since ηF was too high, single yarn breakage occurred at the polymer discharge portion, and the yarn forming property was very poor.

[Comparative Examples 3 and 4]
An 84 dtex / 72 filament yarn was obtained in the same manner as in Example 1 except that the strength and elongation of the yarn obtained by changing the draw ratio were changed as shown in Table 1.
In Comparative Example 3, the strength of the raw yarn was low, and the wear resistance and tear strength of the fabric using the obtained raw yarn were insufficient. In Comparative Example 4, since the draw ratio was high and the elongation of the raw yarn was low, there were many yarn breaks during drawing.

原糸繊度およびフィラメントカウントを表１の通り変更し、実施例１と同様の方法にてフィラメント原糸を得た。
比較例５では原糸のＤＰＦが低すぎるため製糸性が悪く、また得られた原糸を用いた布帛の耐摩耗性および引裂強力が不十分であった。また、比較例６では原糸のＤＰＦが高すぎるため得られた原糸を用いた布帛の風合いが硬かった。
[Comparative Examples 5 and 6]
The raw yarn fineness and filament count were changed as shown in Table 1, and a filament raw yarn was obtained in the same manner as in Example 1.
In Comparative Example 5, since the DPF of the raw yarn was too low, the yarn-making property was poor, and the wear resistance and tear strength of the fabric using the obtained raw yarn were insufficient. In Comparative Example 6, since the DPF of the raw yarn was too high, the texture of the fabric using the obtained raw yarn was hard.
［比較例７］
得られた原糸の△ｎを製糸条件の変更により表１の通り変更した以外は、実施例１と同様の方法にて８４ｄｔｅｘ／７２フィラメントの原糸を得た。比較例７では原糸の△ｎが高いため、耐摩耗性が劣るという結果になった。
[Comparative Example 7]
An 84 dtex / 72 filament yarn was obtained in the same manner as in Example 1 except that Δn of the obtained yarn was changed as shown in Table 1 by changing the yarn production conditions. In Comparative Example 7, since the Δn of the raw yarn was high, the abrasion resistance was inferior.
