Abstract
Description
本発明は、良好な吸水性と優れた速乾性を合わせ持ち、かつふんわり感を向上させたタオル織物、及び当該タオル織物が、圧縮袋内に圧縮状態で封入されている真空パッキングタオルに関する。 The present invention relates to a towel fabric that has both good water absorption and excellent quick-drying properties and also has an improved fluffy feel, and to a vacuum-packed towel in which the towel fabric is sealed in a compressed state in a compression bag.
一般的な綿タオルは、吸水性が高く、身体及び髪などについた水分の拭き取り性に優れるという長所があるが、その反面、優れた吸水性のために洗濯時に多くの水分を含み、水切りが悪くなり、その結果、乾燥時間が長くなり、速乾性に劣るという短所も併せ持つ。そのため、家庭での洗濯のみならず、病院、介護施設、ホテル等の業務用途での洗濯においても、長い乾燥時間と多大な消費電力を必要とするという問題がある。 Ordinary cotton towels have the advantage of being highly absorbent and excellent at wiping off moisture from the body and hair, but on the other hand, because of their excellent absorbency, they absorb a lot of water when washed, which makes it difficult to drain, resulting in a long drying time and poor quick-drying properties. Therefore, there is the problem that long drying times and large amounts of electricity are required not only for washing at home, but also for washing for commercial purposes such as in hospitals, nursing homes, and hotels.
この問題を解決するために、例えば、特許文献１では、パイル糸として、非捲縮性のポリエステル系マルチフィラメント糸と植物性繊維との精紡合撚糸を用いたタオル地が提案されている。 To solve this problem, for example, Patent Document 1 proposes a towel fabric that uses a spun yarn of non-crimping polyester multifilament yarn and vegetable fiber as pile yarn.
しかし、特許文献１に記載のタオル地は、速乾性について十分満足できるものではなく、また、ふんわり感についても改善の余地があった。 However, the towel fabric described in Patent Document 1 is not completely satisfactory in terms of quick-drying properties, and there is also room for improvement in terms of fluffiness.
本発明の目的は、良好な吸水性と優れた速乾性を合わせ持ち、かつふんわり感を向上させたタオル織物、及び当該タオル織物が、圧縮袋内に圧縮状態で封入されている真空パッキングタオルを提供することである。 The object of the present invention is to provide a towel fabric that has good water absorption and quick drying properties, and also has an improved softness, and a vacuum-packed towel in which the towel fabric is sealed in a compressed state in a compression bag.
本発明者は、前記課題を解決すべく鋭意検討を行ったところ、タオル織物を構成する経地糸、緯地糸、及びパイル糸として、ポリエステル短繊維を６５質量％以上含む紡績糸を用いることにより、良好な吸水性と優れた速乾性を合わせ持ち、かつふんわり感を向上させたタオル織物が得られることを見出した。本発明は、かかる知見に基づいて、更に検討を重ねることにより完成したものである。 The inventors conducted extensive research to solve the above problems and discovered that by using spun yarns containing 65% or more polyester staple fibers as the warp yarns, weft yarns, and pile yarns that make up the towel fabric, it is possible to obtain a towel fabric that has good water absorption and quick-drying properties as well as improved fluffiness. The present invention was completed based on this knowledge and through further research.
即ち、本発明は、以下に掲げる態様の発明を提供する。
項１．経地糸、緯地糸、及びパイル糸で構成されるタオル織物であって、
前記経地糸、前記緯地糸、及び前記パイル糸は、ポリエステル短繊維を６５質量％以上含む紡績糸である、タオル織物。

２．真空パッキングタオル
本発明の真空パッキングタオルは、本発明のタオル織物が、圧縮袋内に圧縮状態で封入されているものである。ここで、「圧縮袋内に圧縮状態で封入」とは、タオル織物が圧縮袋内に圧縮した状態（真空パックによる圧縮状態を含む）のままで封止されていることをいう。
2. Vacuum-packed towel The vacuum-packed towel of the present invention is obtained by enclosing the towel fabric of the present invention in a compressed state in a compression bag. Here, "enclosing in a compressed state in a compression bag" means that the towel fabric is sealed in the compression bag while being compressed (including the compressed state by vacuum packing).
圧縮袋の素材及び種類は、本発明のタオル織物を圧縮状態で封入可能なものであれば特に制限されず、例えば、密封可能な、プラスチックフィルム（例えば、ポリエチレン及びポリ塩化ビニールなどの単層フィルム；ポリアミド系合成繊維とポリエチレンとを積層したもの、ナイロンフィルムとポリエチレンフィルムとをポリエチレン層を介して積層したもの、及びナイロンフィルムとポリエチレンフィルムとを積層したものなどのラミネートフィルムなど）の袋、金属箔（例えば、アルミニウム箔など）の袋、プラスチックフィルムと金属箔との複合材の袋などが挙げられる。また、前記袋の開口部に密封チャックを取り付け、かつ真空吸引部に逆止弁を設けた再使用可能なタイプのものでもよい。 The material and type of the compression bag are not particularly limited as long as it can enclose the towel fabric of the present invention in a compressed state. Examples include sealable bags made of plastic film (e.g., monolayer films such as polyethylene and polyvinyl chloride; laminated films such as laminates of polyamide synthetic fibers and polyethylene, laminates of nylon film and polyethylene film with a polyethylene layer between them, and laminates of nylon film and polyethylene film), bags made of metal foil (e.g., aluminum foil), and bags made of composite materials of plastic film and metal foil. In addition, the bag may be of a reusable type having a sealing zipper attached to the opening and a check valve in the vacuum suction section.
圧縮袋の形状及びサイズは特に制限されず、収納されるタオル織物に応じて適宜変更すればよい。なお、圧縮袋は、内部を視認できるように一部又は全体が透明であることが好ましい。 There are no particular limitations on the shape and size of the compression bag, and it may be modified as appropriate depending on the towel fabric to be stored. It is preferable that the compression bag is partially or entirely transparent so that the inside can be seen.
タオル織物の圧縮形状は特に制限されず、例えば、折り畳み状、及びロール状などが挙げられる。 The compressed shape of the towel fabric is not particularly limited, and examples include a folded shape and a rolled shape.
圧縮袋内に封入するタオル織物の枚数は特に制限されず、収納されるタオル織物に応じて適宜変更すればよい。 There is no particular limit to the number of towel fabrics to be enclosed in the compression bag, and this can be changed as appropriate depending on the towel fabrics to be stored.
本発明の真空パッキングタオルは、タオル織物が圧縮袋内に圧縮した状態のままで封止されているため、タオル織物の嵩が減ってコンパクト化できる。それにより、真空パッキングタオルの輸送時および保管時のスペースが小さくなり、輸送コスト及び保管コストを削減できる。また、本発明の真空パッキングタオルは、密封されているため、水害時に真空パッキングタオルが水没したとしても、圧縮袋内のタオル織物は水に濡れることがなく、真空パッキングの開封後すぐにタオル織物を使えるという利点がある。また、本発明のタオル織物は、経地糸、緯地糸、及びパイル糸として、ポリエステル短繊維を６５質量％以上含む紡績糸を用いているので、真空パッキングの開封後にすぐに嵩高くなり、パイル立ちが良く、ふんわりとした肌触りのタオルになるという特徴がある。 The vacuum-packed towel of the present invention has the towel fabric sealed in a compressed state in a compression bag, so the towel fabric is reduced in bulk and can be made compact. This reduces the space required for transporting and storing the vacuum-packed towel, and reduces transport and storage costs. In addition, since the vacuum-packed towel of the present invention is sealed, even if the vacuum-packed towel is submerged in water during a flood, the towel fabric in the compression bag will not get wet, and the towel fabric can be used immediately after the vacuum packing is opened. In addition, the towel fabric of the present invention uses spun yarn containing 65% or more by mass of polyester staple fibers for the warp yarn, weft yarn, and pile yarn, so it has the characteristic of becoming bulky immediately after the vacuum packing is opened, becoming a towel with good pile standing and a soft feel.

・温度：２０±２℃
・湿度：６５±４％ＲＨ
<Evaluation of drying property>
The towel fabrics woven in Examples 1 and 2 and Comparative Example 1 were immersed in water and dehydrated for 2 minutes in a centrifugal dehydrator, and then the time until drying was measured at 30-minute intervals using the drying method described below.
