Description
本発明は、不織布製造用繊維処理剤、ポリエステル短繊維、不織布および不織布の製造方法に関する。詳細には、不織布の製造に用いるポリエステル短繊維に処理する不織布製造用繊維処理剤、該繊維処理剤を処理して得られるポリエステル短繊維、該短繊維を含有する不織布、該短繊維を用いた不織布の製造方法に関する。 The present invention relates to a fiber treatment agent for producing a nonwoven fabric, polyester short fibers, a nonwoven fabric, and a method for producing the nonwoven fabric. In detail, the fiber treatment agent for nonwoven fabric manufacture processed into the polyester short fiber used for manufacture of a nonwoven fabric, the polyester short fiber obtained by processing this fiber treatment agent, the nonwoven fabric containing this short fiber, and this short fiber were used. The present invention relates to a method for manufacturing a nonwoven fabric.
従来から、おしぼりや手拭等の不織布の製造方法として、高圧水流絡合法が用いられており、ポリエステル短繊維（以下、単に短繊維ということがある。）に対してこの方法を適用しようという試みがなされている。そのためには、ポリエステル繊維は一般に疎水性繊維であるため繊維処理剤処理などの方法で親水性を付与する必要がある。 Conventionally, a high-pressure water entanglement method has been used as a method for producing nonwoven fabrics such as hand towels and hand towels, and attempts have been made to apply this method to polyester short fibers (hereinafter sometimes simply referred to as short fibers). Has been made. For this purpose, polyester fibers are generally hydrophobic fibers, and therefore it is necessary to impart hydrophilicity by a method such as treatment with a fiber treatment agent.
親水性を付与する方法としては、短繊維製造工程時において、繊維処理剤により親水性を付与する方法がある。この方法は、短繊維製造時にのみ繊維処理剤を付与すればよく、低コストで生産効率が良いというメリットがある。しかしながら、繊維処理剤が高圧水流絡合処理によって洗い流されてしまい、おしぼりや手拭として使用するために必要な親水性が不足するという問題がある。従って、高圧水流による処理後でも親水性が保持される特性（耐久親水性）を有した処理剤が開発されることが強く望まれている。 As a method for imparting hydrophilicity, there is a method for imparting hydrophilicity with a fiber treatment agent in the short fiber manufacturing process. This method has the advantage that the fiber treatment agent only needs to be applied at the time of short fiber production, and the production efficiency is low and low. However, the fiber treatment agent is washed away by the high-pressure water entanglement treatment, and there is a problem that the hydrophilicity necessary for use as a wet towel or hand towel is insufficient. Therefore, it is strongly desired to develop a treatment agent having a characteristic (durable hydrophilicity) that maintains hydrophilicity even after treatment with a high-pressure water stream.
一方で、ポリエステル短繊維を高圧水流絡合処理する前工程として、ウェブ作製工程が
ある。ウェブ作製工程で、カード通過時に静電気発生量が多いと、ウェブが均一でなくなり、不織布の厚さに斑が生じる。このため、繊維処理剤には、静電気発生の抑制（制電性）および良好なカード通過性が要求され、一般的に界面活性剤を主体にした繊維処理剤が使用される。しかしながら、界面活性剤は起泡する性質が通常あり、高圧水流絡合時において脱落した繊維処理剤による起泡によって、ウェブが乱れ、不織布の厚さに斑が生じ、不織布の品質が低下するという問題がある。
On the other hand, there exists a web preparation process as a pre-process which carries out the high pressure hydroentanglement process of the polyester short fiber. If a large amount of static electricity is generated at the time of passing the card in the web production process, the web is not uniform and unevenness occurs in the thickness of the nonwoven fabric. For this reason, the fiber treatment agent is required to suppress the generation of static electricity (antistatic property) and to have good card passage properties, and generally a fiber treatment agent mainly composed of a surfactant is used. However, the surfactant usually has a foaming property, and the foaming by the fiber treatment agent dropped during the high-pressure water entanglement causes the web to be disturbed, causing unevenness in the thickness of the nonwoven fabric, and the quality of the nonwoven fabric is reduced. There's a problem.
ポリエステル繊維に耐久親水性を付与する例として、特許文献１には、ポリエステル共重合体と、アルキルリン酸エステル塩からなる混合物をポリエステル短繊維に付与する例が開示されている。また、起泡性の問題を解決する例として、特許文献２には、二塩基酸とジオールからなるエステル化合物およびアルキルリン酸エステルを含む繊維処理剤をポリエステル繊維に使用する例が開示されている。 As an example of imparting durable hydrophilicity to a polyester fiber, Patent Document 1 discloses an example in which a mixture comprising a polyester copolymer and an alkyl phosphate ester salt is imparted to a polyester short fiber. In addition, as an example for solving the problem of foamability, Patent Document 2 discloses an example in which a fiber treatment agent containing an ester compound composed of a dibasic acid and a diol and an alkyl phosphate is used for polyester fibers. .
最近になって、再利用の考え方から、何度洗濯等しても親水性が保持され（耐久洗濯性）、繰り返し使用できるおしぼりや手拭等の不織布が脚光を浴び始めている。これまで、高圧水流絡合処理後でも一定の親水性が保持される、つまり耐久親水性を有する繊維処理剤は開発されてきているが、そのような処理剤であっても洗濯等で容易に脱落してしまい、耐久洗濯性を満足できるものはなかった。例えば、特許文献１の例では、高圧水流絡合処理後でも一定の親水性は保持されているが、洗濯等で繊維処理剤が容易に脱落してしまい、耐久洗濯性を満足できるものではない。特許文献２の例では、耐久親水性は不十分であり、耐久洗濯性に至ってはほとんど有しない。 Recently, from the viewpoint of reuse, hydrophilicity is maintained even after many washings (durable washability), and nonwoven fabrics such as hand towels and hand towels that can be used repeatedly have begun to attract attention. Up to now, fiber treatment agents that maintain a certain hydrophilicity even after high-pressure hydroentanglement treatment, that is, durable hydrophilic properties have been developed, but even such treatment agents can be easily washed. None of them fell off and could satisfy the durable washability. For example, in the example of Patent Document 1, a certain hydrophilicity is maintained even after the high-pressure water-entanglement treatment, but the fiber treatment agent easily falls off due to washing or the like, and the durable washability cannot be satisfied. . In the example of patent document 2, durable hydrophilicity is inadequate and has almost no durable washability.
このように、制電性、低起泡性、高圧水流絡合処理後における耐久親水性を満足した上で、さらに耐久洗濯性を満足する繊維処理剤が見出されていないのが現状であり、これらの物性を満足する繊維処理剤の開発が望まれている。
本発明の目的は、不織布製造用繊維に対して、良好な制電性、低起泡性、耐久親水性を付与できる上に、さらに優れた耐久洗濯性を付与できる不織布製造用繊維処理剤、該処理剤を処理して得られるポリエステル短繊維、該短繊維を含有する不織布、該短繊維を用いた不織布の製造方法を提供することにある。
As described above, there is no fiber treatment agent that satisfies the antistatic property, the low foaming property, the durable hydrophilic property after the high-pressure water entanglement treatment, and further satisfies the durable washing property. Therefore, development of a fiber treatment agent satisfying these physical properties is desired.
An object of the present invention is to provide a nonwoven fabric-producing fiber treatment agent that can impart good antistaticity, low foaming property, durable hydrophilicity to the nonwoven fabric-producing fiber, and further impart excellent durability washing properties, An object of the present invention is to provide a polyester staple fiber obtained by treating the treatment agent, a nonwoven fabric containing the staple fiber, and a method for producing a nonwoven fabric using the staple fiber.

本発明の不織布製造用繊維処理剤（以下、繊維処理剤ということがある）は、特定のＡ成分とＢ成分とを特定量含むものである。以下、詳細に説明する。 The fiber treatment agent for producing a nonwoven fabric of the present invention (hereinafter sometimes referred to as a fiber treatment agent) contains a specific amount of a specific A component and a B component. Details will be described below.
[Ａ成分]
Ａ成分は、平均重合度が５００〜３０００であるポリビニルアルコール（以下ポリビニルアルコールをＰＶＡと略すことがある）および／またはその誘導体である。Ａ成分は、後述のＢ成分と併用されることによって、耐久洗濯性を飛躍的に向上させることができる。また、不織布製造用繊維に対して、良好な制電性、低起泡性、耐久親水性を付与できる。Ａ成分単独では、これらの効果、特に耐久洗濯性の効果は発揮されない。
[Component A]
The component A is polyvinyl alcohol having an average degree of polymerization of 500 to 3000 (hereinafter, polyvinyl alcohol may be abbreviated as PVA) and / or a derivative thereof. The A component can drastically improve the durable washability by being used in combination with the B component described later. Moreover, favorable antistaticity, low foaming property, and durable hydrophilicity can be imparted to the nonwoven fabric-producing fiber. A component A alone does not exhibit these effects, particularly the effect of durable washability.
ＰＶＡは、酢酸ビニルを重合して得られるポリ酢酸ビニルを鹸化することにより得られ、下記一般式（１）で表される。また、本発明のＰＶＡは、完全鹸化ＰＶＡ（鹸化度１００モル％）、準完全鹸化ＰＶＡ（鹸化度９０モル％以上１００モル％未満）および部分鹸化ＰＶＡ（鹸化度９０モル％未満）を含む。ＰＶＡの誘導体としては、ＰＶＡの水酸基をハロゲン化アルキル、アルキレンオキシド等によってエーテル化したものや、酢酸ビニルと、塩化ビニル、スチレン等の他の単量体を重合したものを鹸化したもの等が挙げられる。成分Ａとしては、１種または２種以上を併用してもよい。 PVA is obtained by saponifying polyvinyl acetate obtained by polymerizing vinyl acetate, and is represented by the following general formula (1). The PVA of the present invention includes fully saponified PVA (saponification degree 100 mol%), semi-fully saponified PVA (saponification degree 90 mol% or more and less than 100 mol%) and partially saponified PVA (saponification degree 90 mol% or less). Derivatives of PVA include those in which the hydroxyl group of PVA is etherified with an alkyl halide, alkylene oxide or the like, or those obtained by polymerizing other monomers such as vinyl acetate and vinyl chloride or styrene. It is done. Component A may be used alone or in combination of two or more.
（式中、Ｒ１は炭化水素基であり、通常はＲ１＝ＣＨ３である。また、ａ、ｂは負でない数であり、ａ＋ｂは重合度を、（ａ／（ａ＋ｂ））×１００は鹸化度（モル％）を表わす。また、ＯＨ基（ａの部分）とＯＣＯＲ基（ｂの部分）の結合順序は特に問わず、ブロック体、ランダム体いずれでもよい。） (In the formula, R 1 is a hydrocarbon group, usually R 1 = CH 3 , a and b are non-negative numbers, a + b is the degree of polymerization, (a / (a + b)) × 100 Represents the degree of saponification (mol%), and the bonding order of the OH group (part a) and the OCOR group (part b) is not particularly limited, and may be either block or random.)
ＰＶＡの平均重合度は５００〜３０００であり、５００〜２６００が好ましく、１０００〜２０００がさらに好ましい。重合度が５００未満の場合、高圧水流絡合処理後の不織布に一定の耐久親水性を保持させることはできるが、洗濯等により繊維処理剤が容易に脱落し、耐久洗濯性を満足できない。また、高圧水流絡合工程時の発泡の程度が高くなり、得られた不織布の地合が乱れる。一方、重合度が３０００超の場合、制電性が悪くなり、ウェブ作製工程で、カード通過時ウェブが不均一になる場合がある。また、繊維処理剤の水性液の粘度が高くなり、取り扱い難くなる。なお、本発明のＰＶＡの平均重合度は、ＪＩＳ Ｋ６７２６に準拠して測定される値をいう。 The average degree of polymerization of PVA is 500 to 3000, preferably 500 to 2600, and more preferably 1000 to 2000. When the degree of polymerization is less than 500, the non-woven fabric after the high-pressure water entanglement treatment can maintain a certain durability hydrophilicity, but the fiber treatment agent easily falls off due to washing or the like, and the durability washability cannot be satisfied. Moreover, the degree of foaming at the time of the high-pressure water entanglement process becomes high, and the formation of the obtained nonwoven fabric is disturbed. On the other hand, when the degree of polymerization exceeds 3000, the antistatic property is deteriorated, and the web may be non-uniform when passing through the card in the web production process. Moreover, the viscosity of the aqueous liquid of a fiber treatment agent becomes high, and handling becomes difficult. In addition, the average degree of polymerization of PVA of this invention says the value measured based on JISK6726.
また、ＰＶＡの鹸化度は、７０モル％以上が好ましく、７０〜９８モル％がより好ましく、7２〜９６モル％がさらに好ましく、７４〜９２モル％が特に好ましい。鹸化度が７０モル％未満の場合、高圧水流絡合処理後の不織布に一定の耐久親水性を保持させることはできるが、洗濯等により繊維処理剤が脱落し、耐久洗濯性が不十分になることがある。また、ＰＶＡの水溶性が劣り、取り扱い難くなる。なお、本発明のＰＶＡの鹸化度は、ＪＩＳ Ｋ６７２６に準拠して測定される値をいう。 The saponification degree of PVA is preferably 70 mol% or more, more preferably 70 to 98 mol%, further preferably 72 to 96 mol%, particularly preferably 74 to 92 mol%. When the degree of saponification is less than 70 mol%, the nonwoven fabric after the high-pressure water-entanglement treatment can maintain a certain durability hydrophilicity, but the fiber treatment agent falls off due to washing or the like, and the durability washing property becomes insufficient. Sometimes. Moreover, the water solubility of PVA is inferior and handling becomes difficult. In addition, the saponification degree of PVA of this invention says the value measured based on JISK6726.
[Ｂ成分]
Ｂ成分は、炭素数が６〜２２のアルキル基を有するジアルキルスルホサクシネート塩である。Ｂ成分は、前述のＡ成分と併用されることによって、耐久洗濯性を飛躍的に向上させることができる。また、不織布製造用繊維に対して、良好な制電性、低起泡性、耐久親水性を付与できる。Ｂ成分単独では、これらの効果、特に耐久洗濯性の効果は発揮されない。耐久洗濯性を飛躍的に向上させることができる作用は明確にはわからないが、次のように推測される。繊維処理剤が乾燥する過程で、Ｂ成分により、繊維処理剤の表面親水性をコントロールすることができ、Ａ成分中の親水性基がＢ成分の親水性基に引き寄せられることで高い親水性が得られ、さらには、Ａ成分の造膜性により高い耐久洗濯性が得られると推測する。
[B component]
The B component is a dialkyl sulfosuccinate salt having an alkyl group having 6 to 22 carbon atoms. B component can improve durability washability drastically by using together with the above-mentioned A component. Moreover, favorable antistaticity, low foaming property, and durable hydrophilicity can be imparted to the nonwoven fabric-producing fiber. The B component alone does not exhibit these effects, particularly the durable washability effect. Although the action that can dramatically improve the durability of washing is not clearly understood, it is presumed as follows. In the process of drying the fiber treatment agent, the surface hydrophilicity of the fiber treatment agent can be controlled by the B component, and the hydrophilic group in the A component is attracted to the hydrophilic group of the B component, resulting in high hydrophilicity. Further, it is presumed that a high durability washability is obtained by the film forming property of the component A.
Ｂ成分は、炭素数６〜２２のアルキル基を有するものであるが、炭素数８〜１８のアルキル基を有すると好ましく、炭素数１０〜１８のアルキル基を有するとさらに好ましく、炭素数１０〜１６のアルキル基を有すると特に好ましい。アルキル基としては、直鎖、分岐のいずれでもよく、２個のアルキル基は同一であっても異なっていてもよい。アルキル基の炭素数が６未満では、高圧水流絡合処理後の不織布に一定の耐久親水性を保持させることはできるが、洗濯等により繊維処理剤が容易に脱落し、耐久洗濯性を満足できない。一方、アルキル基の炭素数が２２を超えると、不織布製造用繊維に対して、親水性を付与することができなくなる。 The component B has an alkyl group having 6 to 22 carbon atoms, preferably having an alkyl group having 8 to 18 carbon atoms, more preferably having an alkyl group having 10 to 18 carbon atoms, and 10 to 10 carbon atoms. It is particularly preferred to have 16 alkyl groups. The alkyl group may be linear or branched, and the two alkyl groups may be the same or different.

[Polyester short fiber, non-woven fabric and production method thereof]
The polyester staple fiber of the present invention is a fiber obtained by treating a polyester staple fiber body with the above-described fiber treatment agent. The manufacturing method of the polyester staple fiber of this invention includes the process of processing a polyester staple fiber main body with said fiber processing agent.
ポリエステル短繊維本体は、エチレンテレフタレート単位を主体とするポリエステルからなることが好ましく、ポリエチレンテレフタレートであるとさらに好ましい。ポリエステルは、酸成分としてテレフタル酸が５０重量％以上で、それ以外にイソフタル酸、ジフェニルスルホンジカルボン酸、３，５−ジカルボキシベンゼンスルホン酸ナトリウム、ナフタレンジカルボン酸等を１種類または２種類以上を共重合したポリエステルが好ましい。また、グリコール成分としてエチレングリコールが７０重量％以上で、それ以外にジエチレングリコール、ブタンジオール、シクロヘキサンジメタノール、ネオペンチルグリコール等を１種類または２種類以上共重合したポリエステルから構成されるものが好ましい。ポリエステル短繊維本体は、上述したポリエステルを溶融紡糸して製造され、カット長と捲縮は用途により選択される。これらのポリエステル繊維の断面形状は、丸、中空丸、異形、中空異形等いずれの形状であってもよい。 The polyester short fiber main body is preferably made of polyester mainly composed of ethylene terephthalate units, and more preferably polyethylene terephthalate. Polyester has 50% by weight or more of terephthalic acid as an acid component. In addition, isophthalic acid, diphenylsulfone dicarboxylic acid, sodium 3,5-dicarboxybenzene sulfonate, naphthalenedicarboxylic acid, etc. are used in combination. Polymerized polyester is preferred. Moreover, what is comprised from the polyester which copolymerized ethylene glycol 70 weight% or more as a glycol component, and diethylene glycol, butanediol, cyclohexane dimethanol, neopentyl glycol, etc. in addition to that other than that is preferable. The polyester short fiber body is manufactured by melt spinning the above-described polyester, and the cut length and crimp are selected depending on the application.

本発明のポリエステル短繊維において、本発明の繊維処理剤に含まれる不揮発分の付着割合は、ポリエステル短繊維本体に対して、０．０５〜２重量％が好ましく、０．１〜１重量％がさらに好ましい。ポリエステル短繊維本体に対する不揮発分の付着割合が０．０５重量％未満では、耐久洗濯性が低下し、制電性や耐久親水性も低下することがある。一方、不揮発分の付着割合が２重量％を超えると、繊維をカード処理する時に巻付き増加や高圧水流絡合処理の発泡が多くなり生産性が大幅に低下することがある。本発明のポリエステル短繊維の製造方法では、繊維処理剤に含まれる不揮発分の付着割合が上記範囲になるように制御されるとよい。 In the polyester short fiber of the present invention, the adhesion ratio of the nonvolatile content contained in the fiber treatment agent of the present invention is preferably 0.05 to 2% by weight, and 0.1 to 1% by weight with respect to the polyester short fiber main body. Further preferred. When the non-volatile component adhesion ratio to the polyester short fiber body is less than 0.05% by weight, the durable washability is lowered, and the antistatic property and the durable hydrophilic property may be lowered. On the other hand, if the adhesion ratio of the non-volatile component exceeds 2% by weight, when the fiber is carded, the winding increases and the foaming of the high-pressure water entanglement process increases, and the productivity may be significantly reduced. In the manufacturing method of the polyester staple fiber of this invention, it is good to control so that the adhesion rate of the non volatile matter contained in a fiber processing agent may become the said range.

It is desirable that the fiber treatment agent stock solution or diluent is uniformly dispersed during the treatment, and the temperature is usually about 40 ° C to 60 ° C.

本発明の不織布は、本発明のポリエステル短繊維を含有しており、たとえば、高圧水流絡合法等の公知の方法で、ポリエステル短繊維の繊維間を絡合させることによって得られる。以下、本発明の不織布の製造方法の一例として、ポリエステル短繊維を集積させて繊維ウェブを作製し、該繊維ウェブを高圧水流絡合法で処理（高圧水流絡合処理という）する工程を含む、不織布の製造方法について詳しく説明する。 The nonwoven fabric of the present invention contains the polyester short fibers of the present invention, and can be obtained, for example, by entanglement between the fibers of the polyester short fibers by a known method such as a high-pressure hydroentanglement method. Hereinafter, as an example of the method for producing a nonwoven fabric of the present invention, a nonwoven fabric comprising steps of accumulating polyester short fibers to produce a fiber web and treating the fiber web with a high-pressure water entanglement method (referred to as high-pressure water entanglement treatment). The manufacturing method will be described in detail.
まず、本発明のポリエステル短繊維を集積させて繊維ウェブを作製する。繊維ウェブを作製するには、繊維をカード機に供給し、カード機から排出されるフリースを適宜積層すればよい。カード機としては、フリース中の繊維がほぼ一方向に配列するパラレルカード機、フリース中の繊維が無配向となるランダムカード機、前二者の中間程度の配向となるセミランダムカード機、従来綿繊維の開繊に最も一般的に使用されているフラットカード機等を使用することができる。カード機から排出されたフリースを、そのまま多数枚重ねて、一方向に繊維が配列したウェブまたは繊維が無配向となっている繊維ウェブとしてもよい。また、一方向に繊維が配列したフリースを、各フリースの繊維が交差する状態で多数枚重ねて、縦・横均一な繊維ウェブとしてもよい。本発明においては、縦・横の引張強度が同等である方が好ましいので、繊維ウェブとしても、繊維が無配向となっている繊維ウェブまたは各フリース間の繊維が直交している繊維ウェブを採用することが好ましい。 First, a polyester web of the present invention is accumulated to produce a fiber web. In order to fabricate the fiber web, the fibers are supplied to the card machine, and the fleece discharged from the card machine may be appropriately laminated. The card machine includes a parallel card machine in which the fibers in the fleece are arranged in almost one direction, a random card machine in which the fibers in the fleece are non-oriented, a semi-random card machine in which the former two are oriented in the middle, and conventional cotton A flat card machine or the like that is most commonly used for fiber opening can be used. A large number of fleeces discharged from the card machine may be stacked as they are to form a web in which fibers are arranged in one direction or a fiber web in which fibers are not oriented. Alternatively, a plurality of fleeces in which fibers are arranged in one direction may be stacked in a state where the fibers of each fleece intersect to form a uniform longitudinal and lateral fiber web. In the present invention, since it is preferable that the longitudinal and lateral tensile strengths are equal, a fiber web in which fibers are non-oriented or fibers between each fleece are orthogonal is used as the fiber web. It is preferable to do.
このようにして得られた繊維ウェブは、本発明のポリエステル短繊維のみで構成されていてもよいし、他種繊維とともに構成されていてもよい。繊維ウェブ中に含有される他種繊維としては、従来公知の天然繊維、再生繊維、合成繊維等が用いられる。これらの繊維を１ 種または２ 種以上併用してもよい。天然繊維としては、たとえば、綿や羊毛や絹等が挙げられる。再生繊維としては、たとえば、レーヨン繊維等が挙げられる。合成繊維としては、たとえば、ポリアミド系繊維、ポリオレフィン系繊維、ポリアクリル系繊維、ポリビニルアルコール系繊維等が挙げられる。合成繊維は、一般に使用されている非複合型繊維であってもよいし、異種重合体の組み合わせよりなる芯−鞘型複合繊維やサイドバイサイド型複合繊維でもよい。また、このような他種繊維は、ポリエステル短繊維と同様に、短繊維であるのが好ましい。これは、ポリエステル短繊維と他種繊維とが均一に混合しやすくなるからである。 Thus, the obtained fiber web may be comprised only with the polyester staple fiber of this invention, and may be comprised with the other kind fiber. As other kinds of fibers contained in the fiber web, conventionally known natural fibers, regenerated fibers, synthetic fibers and the like are used. These fibers may be used alone or in combination of two or more. Examples of natural fibers include cotton, wool, and silk. Examples of the recycled fiber include rayon fiber. Examples of synthetic fibers include polyamide fibers, polyolefin fibers, polyacrylic fibers, and polyvinyl alcohol fibers. The synthetic fiber may be a commonly used non-composite fiber, or a core-sheath composite fiber or a side-by-side composite fiber made of a combination of different polymers. Moreover, it is preferable that such other fiber is a short fiber like a polyester short fiber. This is because the polyester short fibers and other types of fibers can be easily mixed uniformly.
繊維ウェブの重量（目付） は、１０〜１５０ｇ／ｍ２程度であるのが好ましい。目付が１０ｇ／ｍ２未満であると、繊維密度が小さくなって、三次元的絡合が不十分になる傾向が生じる。一方、目付が１５０ｇ／ｍ２を超える場合も、単位面積当りの繊維量が多すぎて、全ての繊維に高圧水流絡合処理によるエネルギーを与えにくくなり、三次元的絡合が不十分になる傾向が生じる。 The weight (weight per unit area) of the fiber web is preferably about 10 to 150 g / m 2 . When the basis weight is less than 10 g / m 2 , the fiber density becomes small, and the three-dimensional entanglement tends to be insufficient. On the other hand, when the basis weight exceeds 150 g / m 2 , the amount of fibers per unit area is too large, and it becomes difficult to give all fibers energy by high-pressure water entanglement treatment, resulting in insufficient three-dimensional entanglement. A trend arises.
高圧水流絡合処理については、二段階またはそれ以上に別けて施すのが好ましい。すなわち、第一段階の高圧水流絡合処理においては、高圧水流の噴射圧力を低くして、繊維に与える運動量を少なくし、繊維ウェブの地合が乱れるのを防止しながら、繊維相互間にある程度の予備的な三次元的絡合を与える。この第一段階における噴射圧力としては、５〜３０ｋｇ／ｃｍ２・Ｇ程度であるのが好ましい。噴射圧力が５ｋｇ／ｃｍ２・Ｇ未満であると、繊維相互間に三次元的絡合が殆ど生じないおそれがある。また、噴射圧力が３０ｋｇ／ｃｍ２・Ｇを超えると、繊維ウェブの地合が乱れるおそれがある。このような第一段階の高圧水流絡合処理によって、繊維に絡合が与えられ、ある程度、繊維が拘束された状態で、第二段階の高圧水流絡合処理を施す。この際の噴射圧力は、第一段階の噴射圧力よりも高くして、繊維に大きな運動量を与え、繊維相互間の三次元的絡合をさらに進行させるのである。第二段階における噴射圧力は、４０〜１５０ｋｇ／ｃｍ２・Ｇ程度が好ましい。噴射圧力が４０ｋｇ／ｃｍ２・Ｇ未満であると、繊維相互間の三次元的絡合の進行が不十分になる傾向が生じる。また、噴射圧力が１５０ｋｇ／ｃｍ２・Ｇを超えると、繊維相互間の三次元的絡合が強固になりすぎて、得られる不織布の柔軟性や嵩高性が低下する傾向が生じる。また、第一段階の処理で、ある程度繊維が拘束されているにもかかわらず、得られる不織布の地合が乱れる恐れもある。以上のような方法によると、得られる不織布の地合の乱れが少なくなり、且つ引張強度が高くなるという利点がある。 The high-pressure water entanglement treatment is preferably performed in two steps or more. That is, in the first stage high pressure water entanglement process, the jet pressure of the high pressure water flow is lowered, the momentum given to the fibers is reduced, and the formation of the fiber web is prevented from being disturbed to some extent between the fibers. Gives a preliminary three-dimensional entanglement. The injection pressure in the first stage is preferably about 5 to 30 kg / cm 2 · G. When the injection pressure is less than 5 kg / cm 2 · G, there is a possibility that three-dimensional entanglement hardly occurs between the fibers. Moreover, when the injection pressure exceeds 30 kg / cm 2 · G, the formation of the fiber web may be disturbed. By such a first stage high pressure hydroentanglement process, the fibers are entangled, and the second stage high pressure hydroentanglement process is performed while the fibers are restrained to some extent. The injection pressure at this time is higher than the injection pressure in the first stage, gives a large momentum to the fibers, and further advances the three-dimensional entanglement between the fibers. The injection pressure in the second stage is preferably about 40 to 150 kg / cm 2 · G. If the injection pressure is less than 40 kg / cm 2 · G, the three-dimensional entanglement between fibers tends to be insufficient. On the other hand, when the spray pressure exceeds 150 kg / cm 2 · G, the three-dimensional entanglement between the fibers becomes too strong, and the flexibility and bulkiness of the resulting nonwoven fabric tend to decrease. In addition, in the first stage of processing, although the fibers are restrained to some extent, the resulting nonwoven fabric may be disturbed. According to the above method, there is an advantage that the resulting nonwoven fabric is less disturbed and the tensile strength is increased.
繊維ウェブに高圧水流絡合処理を施す際、繊維ウェブは、通常、支持体に担持されている。すなわち、高圧水流絡合処理が施される側とは、反対面に支持体が置かれている。この支持体は、繊維ウェブに施された高圧水流を良好に通過させるものであれば、どのようなものでも使用でき、例えばメッシュスクリーンや有孔板等が採用される。一般的には、金網等のメッシュスクリーンが採用され、また孔の大きさは、２０〜１００メッシュ程度であるのが好ましい。 When the high-pressure hydroentanglement treatment is performed on the fiber web, the fiber web is usually carried on a support. In other words, the support is placed on the opposite side of the side subjected to the high-pressure water entanglement process. Any material can be used as the support so long as it allows a high-pressure water flow applied to the fiber web to pass well. For example, a mesh screen or a perforated plate is used. In general, a mesh screen such as a wire mesh is adopted, and the size of the hole is preferably about 20 to 100 mesh.

After the fiber web is subjected to high-pressure water flow entanglement treatment, the fiber web is impregnated with a liquid such as water or hot water used as a liquid flow, and this liquid is removed by a conventionally known method. A nonwoven fabric is obtained. Here, as a method of removing the liquid, first, excess liquid is mechanically removed using a squeezing device such as a mangle roll, and then the remaining liquid is removed using a drying device such as a continuous hot air dryer. A removal method or the like is used. The nonwoven fabric obtained as described above has sufficient three-dimensional entanglement between fibers, and has sufficient tensile strength for use as a material for hand towels, hand towels, and the like.
