PROBLEM TO BE SOLVED: To provide non-woven fabric for curtains, having a good web uniformity and design and also to provide a method of manufacturing the same.SOLUTION: Non-woven fabric for curtains is improved on web uniformity compared with normal spunbond non-woven fabric by using fine polyethylene terephthalate short fiber. By using different fibers such as polyamide fiber, polypropylene fiber, or the like that are more likely to have hue differences compared with polyethylene terephthalate short fiber and crystalline thermally adhesive fiber, after dyeing with disperse dye, the non-woven fabric for curtains is given design.

Description

本発明は、ウェブ均整度に優れ、染色加工後に意匠性を付与されたブラインドカーテン、ロールカーテン、プリーツカーテン向けのカーテン用不織布に関するものである。The present invention relates to a nonwoven fabric for curtains for blind curtains, roll curtains, and pleated curtains, which have excellent web leveling and are given design properties after dyeing.

従来から、家屋やオフィス等において、ブラインドカーテン、ロールカーテン、プリーツカーテン等のカーテンが用いられている。その生地としては織布や不織布などが多いが、その中でも特に熱可塑性樹脂からなる不織布は、製造や他の素材との複合化が容易であり、また、必要に応じて種々の特性を付与しやすいことから、不織布を用いたカーテン用の基材が多く提案されている。Conventionally, curtains such as blind curtains, roll curtains, and pleated curtains have been used in houses and offices. As the fabric, there are many woven fabrics and nonwoven fabrics. Among them, nonwoven fabrics made of thermoplastic resins are particularly easy to manufacture and composite with other materials, and give various properties as needed. Since it is easy, many base materials for curtains using a nonwoven fabric have been proposed.

特許文献1にはテカリのない、意匠性に優れたカーテン用基材及びアコーデオンカーテンが開示されている。しかしながら、軟質塩化ビニルシートを組み合わせることで製造工程が増えコスト高になる。またはこの素材ではプリーツ性がないため用途が限定される。
特許文献2には必要な機械強度を有しつつ、軽量性およびコンパクトな収納特性に優れたカーテン用基材が開示されている。しかしながら、機械強度に優れた延伸一方向不織布を用いているが意匠性などは考慮されていない。

Patent Document 1 discloses a curtain base material and an accordion curtain that have no design and are excellent in design. However, combining the soft vinyl chloride sheet increases the manufacturing process and increases the cost. Or this material has limited pleatability, so its use is limited.
Patent Document 2 discloses a curtain base material that has the required mechanical strength and is excellent in light weight and compact storage characteristics. However, although a stretched unidirectional nonwoven fabric excellent in mechanical strength is used, design properties and the like are not considered.

Figure 2013212345
Pleated curtains according to the above examples and comparative examples were produced using a dyeing machine and a pleating machine, and the web leveling, design properties, and pleating properties were evaluated. In Table 2, “◯” indicates “good” as a pleated curtain, “Δ” indicates “pass” as a curtain member, and × indicates “defective” as a curtain member.

通常のスパンボンド不織布はウェブ均整度、意匠性を考慮していないのでウェブ均整度が悪いところは製品とは使用できず、ロスの原因となった。また意匠性も考慮されておらず、和紙などの他部材との競争に負けていた。本発明のカーテン基材を用いたブラインドカーテンではウェブ均整度の向上が見られ、スパンボンド不織布と対比して意匠性も付与されていた。Since ordinary spunbonded nonwoven fabrics do not take into account the web leveling and design properties, those with poor web leveling cannot be used as products, causing loss. In addition, the design was not taken into consideration, and it lost the competition with other members such as Japanese paper. In the blind curtain using the curtain base material of the present invention, the web leveling degree was improved, and the design property was also provided in contrast to the spunbonded nonwoven fabric.

本発明のカーテン用不織布は、ウェブ均整度に優れ、分散染料での染色加工することで意匠性も付与できるのでブラインドカーテン、ロールカーテン、プリーツカーテン等のカーテンに用いることができ、カーテン以外に和紙、壁紙などのインテリア商品として広い用途範囲で使用できる。The nonwoven fabric for curtains of the present invention is excellent in web leveling and can be used for curtains such as blind curtains, roll curtains, and pleated curtains by being dyed with disperse dyes.

本発明のカーテン用不織布は細繊度のポリエチレンテレフタレート短繊維を用いることで通常のスパンボンド不織布と比較して、ウェブ均整度を向上し、分散染料等を用いた染色後にポリエチレンテレフタレート短繊維、結晶性の熱接着性繊維と比較して、色相差が生じやすいポリアミド繊維、ポリプロピレン繊維などの異繊維を用いることで意匠性を付与している。
また生産工程は単一のため生産性は高く、カーテンメーカーの多様なニーズに対応が可能である。
The nonwoven fabric for curtains of the present invention improves the web leveling by using fine polyethylene terephthalate short fibers with a fineness compared to ordinary spunbond nonwovens, and after dyeing with disperse dyes, the polyethylene terephthalate short fibers and crystallinity Designability is imparted by using a different fiber such as a polyamide fiber or a polypropylene fiber, which tends to cause a hue difference as compared with the heat-adhesive fiber.
In addition, since the production process is single, it is highly productive and can meet the diverse needs of curtain manufacturers.
