A method for manufacturing the same is also provided.

Description

本発明は、ポリオレフィン類からなる繊維とエラストマーからなる繊維が微細に分散されて混合され形成されている不織布及びその製造方法に関する。   The present invention relates to a nonwoven fabric in which fibers made of polyolefin and fibers made of elastomer are finely dispersed and mixed, and a method for producing the same.

近年、不織布はさまざまな用途に使用されてきており、その用途に応じて各種特性の向上が要求される。例えば、紙おむつ、生理用ナプキン等の衛生材料の一部、湿布材の基布等に用いられる不織布は、触感が良く、耐水性があり透湿性に優れることが要求される。また使用される箇所によっては加えて伸縮性も求められる。さらには、衛生材料などを構成する不織布素材間では、接着の際にヒートシール性が求められる。   In recent years, non-woven fabrics have been used for various purposes, and improvements in various properties are required depending on the uses. For example, non-woven fabrics used for sanitary materials such as disposable diapers and sanitary napkins, and base materials for poultices are required to have good tactile sensation, water resistance and excellent moisture permeability. In addition, stretchability is also required depending on the location used. Furthermore, heat-sealability is required between the non-woven fabric materials that constitute sanitary materials and the like during bonding.

これらの特性は、単一のポリマーからなる繊維で構成される不織布では、達成が難しく、たとえば強度と柔軟性を兼ね備えた不織布とするためスパンボンド不織布をバイコンポネーント繊維からなるものとしたり、加えて耐水性を向上させたりするために、メルトブロー不織布を積層することが行われている。また、伸縮性を有し触感にも優れていてべとつきのない不織布とするために、伸縮性素材からなる不織布に、伸長性の不織布を積層することが行われる。そして不織布を積層するためには層間接着性に優れた素材の組み合わせとしなければならなかった。さらには、異種のポリマーからなる不織布同士のヒートシールには、加工が複雑となるホットメルト等による接着工程が必要となる。   These properties are difficult to achieve with a nonwoven fabric composed of fibers made of a single polymer. For example, a spunbond nonwoven fabric composed of bicomponent fibers in order to obtain a nonwoven fabric having both strength and flexibility, In addition, in order to improve water resistance, a melt blown nonwoven fabric is laminated. Moreover, in order to make a non-woven fabric that has stretchability and excellent tactile sensation, a stretchable non-woven fabric is laminated on a non-woven fabric made of a stretchable material. And in order to laminate a nonwoven fabric, it had to be made into the combination of the material excellent in interlayer adhesiveness. Furthermore, in order to heat-seal non-woven fabrics made of different types of polymers, a bonding process using hot melt or the like that complicates processing is required.

また、異なる素材が有している両方の特性を併せ持つ不織布とするために、異種のポリマーからなる長繊維不織布層を積層して、ウォータージェットや、ニードルパンチなどの機械的な交絡を行う方法、あるいは接着剤を用いるケミカルボンドを行う方法がある。機械的な交絡方法では、生産性が落ちるし、得られたウェブの強度、毛羽立ち等、特におむつ等吸収性物品で求められる低目付(30g/m以下)に対して実用性がない。ケミカルボンドによる方法では、加工が複雑になるという問題点があった。 In addition, in order to make a nonwoven fabric having both characteristics of different materials, a method of laminating a long-fiber nonwoven fabric layer made of different polymers and performing mechanical entanglement such as water jet or needle punch, Alternatively, there is a method of performing chemical bonding using an adhesive. In the mechanical entanglement method, the productivity is lowered, and there is no practicality with respect to the low weight per unit area (30 g / m 2 or less) required for absorbent articles such as diapers, such as strength and fuzz of the obtained web. The chemical bond method has a problem of complicated processing.

本発明は、ポリオレフィン類とエラストマーとが有している特性を併せ持つ、触感が良く、伸縮性に優れる不織布を提供することを目的とする。   An object of this invention is to provide the nonwoven fabric which has the characteristics which polyolefins and an elastomer have, which is good in touch and excellent in stretchability.

本発明によれば、 本発明によれば、同一ダイに配設された異なるノズルから、ポリオレフィン類とエラストマーからなる異種の溶融ポリマーを同時に押出してスパンボンド法により溶融紡糸し、ポリオレフィン類からなる繊維とエラストマーからなる繊維が混合された混合繊維からなる不織布ウェブに熱エンボス加工により交絡処理を施した不織布が提供される。
が提供される。

また、本発明により、前記の混合繊維からなる不織布を、少なくとも1層有する積層体が提供される。   Moreover, the laminated body which has at least 1 layer of the nonwoven fabric which consists of said mixed fiber is provided by this invention.

本発明の混合繊維からなる不織布は、ポリオレフィン類とエラストマーとが有している特性を併せ持つ不織布となるので、触感が良く、伸縮性に優れる単一層の不織布ができる。本発明の混合繊維からなる不織布を積層した積層体では、ポリオレフィン類とエラストマーとが有している特性を併せ持つ不織布層が介在するので、従来のものよりも柔軟性、耐水性及び層間接着性などに優れた積層不織布が得られる。本発明の混合繊維からなる不織布の製造方法によれば、ポリオレフィン類からなる繊維とエラストマーからなる繊維が微細に分散されて混合されているので、ポリオレフィン類とエラストマーとが有している特性を併せ持つ不織布を得ることができる。   Since the nonwoven fabric made of the mixed fiber of the present invention is a nonwoven fabric having the characteristics of polyolefins and elastomers, a single layer nonwoven fabric having good tactile sensation and excellent stretchability can be obtained. In the laminate in which the nonwoven fabric composed of the mixed fibers of the present invention is laminated, a nonwoven fabric layer having the characteristics of polyolefins and elastomers intervenes, so flexibility, water resistance, interlayer adhesion, etc. than conventional ones A laminated nonwoven fabric excellent in the above can be obtained. According to the method for producing a nonwoven fabric composed of the mixed fibers of the present invention, since the fibers composed of polyolefins and the fibers composed of elastomers are finely dispersed and mixed, it has the characteristics of polyolefins and elastomers. A nonwoven fabric can be obtained.

本発明に係る混合繊維からなる不織布及びその製造方法並びに該不織布からなる積層体について具体的に説明する。
本発明の不織布に用いられる混合繊維は、同一ダイに配設された異なるノズルから、異種の溶融ポリマーを同時に押出して溶融紡糸し、異種のポリマーからなる繊維が混合されたものである。
The nonwoven fabric consisting of the mixed fibers according to the present invention, the production method thereof, and the laminate comprising the nonwoven fabric will be specifically described.
The mixed fiber used in the nonwoven fabric of the present invention is a fiber in which different types of molten polymers are simultaneously extruded and melt-spun from different nozzles arranged on the same die, and fibers made of different types of polymers are mixed.

本発明において、異種のポリマーとは、ポリエチレンやポリプロピレン等のポリオレフィン類と、ポリオレフィン系エラストマー、ポリスチレン系エラストマー、ポリエステル系エラストマーポリアミド系エラストマー及びポリウレタン等のエラストマーからなる組み合せである。   In the present invention, the different polymer is a combination of polyolefins such as polyethylene and polypropylene, and elastomers such as polyolefin elastomer, polystyrene elastomer, polyester elastomer polyamide elastomer and polyurethane.

混合繊維は、スパンボンド法により溶融紡糸されて得られるものが好ましい。また、混合繊維は、メルトブロー法により溶融紡糸されて得られるものが好ましい。以下それぞれについて、説明する。
スパンボンド法による混合繊維の製造においては、ポリオレフィン類とエラストマーから選ばれた2種のポリマーを、別々の押出機等により溶融する。溶融されたポリマーは、同一のダイに導かれ、ダイに設けられた多数のノズルから吐出されて紡糸される。2種類のポリマーは、ダイに配設された異なるノズルから吐出される。このとき、2種類のポリマーの吐出ノズルを、例えば、図2のように配置しておけば、2種類の繊維の混合状態や割合を自由に制御できる。ノズルから吐出されたフィラメントは、高速のエア流により冷却、延伸されて捕集コンベアーに堆積され不織布ウェブが形成される。
The mixed fiber is preferably obtained by melt spinning by a spunbond method. The mixed fiber is preferably obtained by melt spinning by a melt blow method. Each will be described below.
In the production of mixed fibers by the spunbond method, two kinds of polymers selected from polyolefins and elastomers are melted by separate extruders or the like. The melted polymer is guided to the same die, discharged from a number of nozzles provided on the die, and spun. The two types of polymers are discharged from different nozzles disposed on the die. At this time, if two types of polymer discharge nozzles are arranged as shown in FIG. 2, for example, the mixed state and ratio of the two types of fibers can be freely controlled. The filament discharged from the nozzle is cooled and stretched by a high-speed air flow, and deposited on a collecting conveyor to form a nonwoven web.

その後不織布ウェブは交絡処理されてスパンボンド不織布が得られる。交絡処理の方法としては、エンボスロールを用いた熱エンボス加工、超音波による融着、ウォータージェットによる交絡、ホットエアースルーによる繊維の融着、ニードルパンチを用いた交絡などを挙げることができる。   The nonwoven web is then entangled to obtain a spunbond nonwoven. Examples of the entanglement treatment method include heat embossing using an embossing roll, ultrasonic fusion, entanglement using a water jet, fiber fusion using hot air through, and entanglement using a needle punch.

メルトブロー法による混合繊維の製造においては、ポリオレフィン類とエラストマーから選ばれた2種のポリマーを、別々の押出機等により溶融する。溶融されたポリマーは、同一のメルトブローダイに導かれ、ダイに設けられ一列に並んだ多数のノズルから空気の二つの収束する高速加熱気流中に吐出されて紡糸される。2種類のポリマーは、ダイに配設された異なるノズルから吐出される。このとき、2種類のポリマーの吐出ノズルを、例えば、図4のように配置しておけば、2種類の繊維の混合状態や割合を自由に制御できる。ノズルから吐出されたマイクロファイバーは、捕集スクリーン上に堆積されメルトブロー不織布が得られる。メルトブロー不織布の場合にも、必要に応じて、後工程で交絡処理を施しても良い。   In the production of mixed fibers by the melt blow method, two kinds of polymers selected from polyolefins and elastomers are melted by separate extruders or the like. The melted polymer is guided to the same melt blow die, and discharged from two or more nozzles arranged in a row in the die into two converging high-speed heated air streams of air to be spun. The two types of polymers are discharged from different nozzles disposed on the die. At this time, if two types of polymer discharge nozzles are arranged as shown in FIG. 4, for example, the mixed state and ratio of the two types of fibers can be freely controlled. Microfibers discharged from the nozzle are deposited on a collection screen to obtain a melt blown nonwoven fabric. Also in the case of a melt blown nonwoven fabric, an entanglement process may be performed in a subsequent process, if necessary.

伸長性素材となるポリエチレンやポリプロピレンと伸縮性素材となるエラストマーとを用いた混合繊維からなる不織布を製造すれば、伸縮性に優れる単一層の不織布が得られる。   If a non-woven fabric made of mixed fibers using polyethylene or polypropylene as an extensible material and an elastomer as an elastic material is produced, a single-layer non-woven fabric having excellent elasticity can be obtained.

このように本発明の不織布は、従来得られなかった特性を併せ持つ単一層の不織布並びに積層体が得られる。そして、積層体の層間接着性の良い素材の組み合せに対する自由度も増え、これにより、不織布の飛躍的な用途の拡大が期待されるものである。   Thus, the nonwoven fabric of this invention can obtain the single layer nonwoven fabric and laminated body which have the characteristic which was not obtained conventionally. And the freedom degree with respect to the combination of a raw material with good interlayer adhesiveness of a laminated body also increases, and, thereby, the expansion of the use of a nonwoven fabric is anticipated.
