Abstract
Description
本発明は、主に衣料及び寝装寝具等に用いられる、吸湿発熱性、吸放湿性、及び保温性に優れた環境配慮型の粒状のわたに関する。 The present invention relates to an environment-friendly granular cotton that is mainly used for clothing, bedding, etc., and has excellent hygroscopic heat generation, moisture absorption / desorption, and heat retention.
従来から、冬の寒冷時期には身体の保温性を得るために、表地布帛などの間に、羽毛や中入れわたといった保温材などを使用した、外気と内衣や肌との間に空気層を有する断熱構造とした防寒衣類、寝具を使用している。
このように保温性を持たせる目的で使用される素材形態としては、羽毛、わた、最近では、粒状わたといった素材が使用されているのが一般的になってきている。
他方、吸放湿性、吸湿発熱性を有するアクリル系繊維やセルロース系繊維が開発されている。これらの繊維をわたに適用して温かさや軽さの機能を発現することも試みられているが、単に混用するだけでは、わた内の緻密な空気層が得られないことから、保温性に関して十分満足できるものは得られていない。
また、近年では、世界的に地球環境への意識が高まっており、廃プラスチック化や二酸化炭素の排出量の削減といった課題が企業に課せられている。また、この取り組みは。企業イメージにも大きく左右されるところである。
Conventionally, in order to obtain heat retention of the body in the cold winter season, an air layer is provided between the outside air and the inner garment or skin by using a heat insulating material such as feathers or inner cloth between the outer fabric and the like. We use cold-weather clothing and bedding that have a heat insulating structure.
As a material form used for the purpose of providing heat retention in this way, materials such as feathers, cotton, and recently, granular cotton have become common.
On the other hand, acrylic fibers and cellulosic fibers having hygroscopicity and heat absorption and heat generation have been developed. Attempts have been made to apply these fibers to the cotton to develop the functions of warmth and lightness, but simply mixing them does not provide a dense air layer inside the cotton, so heat retention is sufficient. I haven't got anything that I'm happy with.
Moreover, in recent years, awareness of the global environment has been increasing worldwide, and companies have been faced with issues such as waste plasticization and reduction of carbon dioxide emissions. Also, what is this initiative? It is also greatly influenced by the corporate image.
これらの問題を解決するため、一手法として、天然繊維素材を選定することが挙げられる。例えば、わた、麻、カポック、パンヤ、亜麻、大麻、芋麻、羊毛、アルパカ、カシミヤ、モヘヤなどが代表的であるが、その中でも最近一注目を浴びているのが植物繊維のカポックである。
一般に、植物繊維カポックは、これまで、軽量、撥水性、繊維が緻密な特性を持つ素材であることから、救命胴衣などの資材分野、枕やぬいぐるみなどの寝具、雑貨品の単なる詰めわたとして使用されていた。
しかしながら、植物繊維カポックのわた生産における加工に関しては、いくつかの問題点があった。その一つは、わた状にするとき、繊維長が短いため繊維が脱落し易いことである、また、製品のドライクリーニング後の繊維のへたりが発生し、高品質なわたを提供する上ではカポックの使用は敬遠されていた。
In order to solve these problems, one method is to select a natural fiber material. For example, cotton, hemp, kapok, panya, flax, cannabis, potato hemp, wool, alpaca, cashmere, mohair, etc. are typical, but among them, the plant fiber kapok has recently attracted a lot of attention.
In general, plant fiber kapok has been used as a material field such as life jackets, bedding such as pillows and stuffed animals, and mere stuffing of miscellaneous goods because it is a material that is lightweight, water repellent, and has dense fibers. It had been.
However, there are some problems with the processing of plant fiber kapok in cotton production. One of them is that the fibers are easy to fall off due to the short fiber length when they are made into cotton, and the fibers are settled after dry cleaning of the product, so that high quality cotton can be provided. The use of kapok was shunned.
以下の特許文献１では、繊維の粒状体を大きく丸く作るための方法が記載されているが、風合いが硬かったり、へたり易いという問題がある。
また、以下の特許文献２では、ポリトリメチレンテレフタレート短繊維を一定混率以上含ませることで風合い、弾力性を向上させる方法が開示されているが、吸湿発熱性、吸放湿性を謳えるものではない。
また、以下の特許文献３では、カポック綿の脱落を防止するために他の素材と結合剤を介して不均一に混合結合されている複合基材が開示されているが、結合剤を付与した後にキュアリングする工程が必要であり、風合いが低下、生産性も悪化することから実用化は進んでいない。
The following Patent Document 1 describes a method for making fiber granules into a large round shape, but there is a problem that the texture is hard or easily settled.
Further, Patent Document 2 below discloses a method of improving texture and elasticity by containing polytrimethylene terephthalate short fibers in a certain mixing ratio or more, but it does not claim hygroscopic heat generation and moisture absorption / desorption. No.
Further, in Patent Document 3 below, a composite base material that is non-uniformly mixed and bonded to another material via a binder in order to prevent the kapok cotton from falling off is disclosed, but a binder is added. A process of curing is required later, and the texture is lowered and the productivity is also deteriorated, so that the practical use has not progressed.
かかる従来技術の問題点に鑑み、本発明が解決しようとする課題は、吸湿発熱性、吸放湿性、及び保温性を兼ね備えた環境配慮型の粒状のわたを提供することである。 In view of the problems of the prior art, an object to be solved by the present invention is to provide an environment-friendly granular wadding that has hygroscopic heat generation, moisture absorption and desorption, and heat retention.
本願発明者らは、かかる課題を解決すべく鋭意検討し実験を重ねた結果、軽くて、緻密であるうえに、中空率約８０％という高中空天然繊維であるという植物繊維カポックの特徴を生かして、保温性、断熱効果の特性を発現させるために、主にこの植物繊維カポックを使用し、羊毛、アルパカ、カシミヤなどの動物繊維とセルロース繊維と合成繊維を適正な混率で用いてわたを作ることで、わた本来の必要とされる特性（吸湿発熱性、吸放湿性、保温率）が得られることを予想外に見出し、本願発明を完成するに至ったものである。 As a result of diligent studies and experiments to solve this problem, the inventors of the present application have taken advantage of the characteristics of plant fiber Capoc, which is a highly hollow natural fiber with a hollow ratio of about 80%, in addition to being light and dense. In order to develop the characteristics of heat retention and heat insulation effect, this plant fiber capoc is mainly used, and animal fibers such as wool, alpaca, and cashmere, cellulose fibers, and synthetic fibers are used in an appropriate mixing ratio to make cotton. As a result, it was unexpectedly found that the originally required characteristics (moisture absorption and heat generation, moisture absorption and desorption, heat retention rate) of the fiber could be obtained, and the present invention was completed.

本実施形態のわたは、吸湿性繊維と疎水性繊維が混合されてなり、吸湿性繊維の少なくとも一部に植物繊維カポック（以下、カポック繊維ともいう。）が含有されている。
本明細書中、用語「吸湿性繊維」とは、天然植物繊維カポック、動物繊維、セルロース繊維等の公定水分率６％以上の繊維をいう。
カポックとは、東南アジアを中心に広く生育されるパンヤ科の木であり、その種子から採れる繊維（わた毛）を利用する目的で広く栽培されている。天然植物繊維カポックは、繊維長２ｍｍ〜７ｍｍほどの環境負荷が小さい植物繊維であり、極めて軽くて、緻密であるうえに、中空率約８０％という高中空構造であることを特徴とする。
The cotton of the present embodiment is a mixture of hygroscopic fibers and hydrophobic fibers, and at least a part of the hygroscopic fibers contains plant fiber kapok (hereinafter, also referred to as kapok fiber).
In the present specification, the term "hygroscopic fiber" refers to a fiber having an official moisture content of 6% or more, such as natural plant fiber kapok, animal fiber, and cellulose fiber.
Kapok is a tree of the Panya family that grows widely mainly in Southeast Asia, and is widely cultivated for the purpose of utilizing the fiber (fluff) obtained from its seeds. The natural plant fiber Kapok is a plant fiber having a fiber length of about 2 mm to 7 mm and having a small environmental load, and is characterized by being extremely light and dense, and having a high hollow structure having a hollow ratio of about 80%.
本実施形態のわたには、吸湿性繊維である、植物繊維カポック、動物繊維、及びセルロース繊維が、合計混率２０ｗｔ％〜６０ｗｔ％で含まれていることを特徴とする。合計混率が２０ｗｔ％未満であると、わたに必要とされる吸湿発熱性、吸放湿性、及び／又は保温性が損なわれる。他方、合計混率が６０ｗｔ％を超えると、疎水性繊維である合成繊維、例えば、ポリエステル繊維の混率が低下することから、かさ高性や洗濯耐久性が著しく低下し、わた形態が保持されず、商品性が失われる。吸湿性繊維である、植物繊維カポック、動物繊維、及びセルロース繊維の合計混率は、好ましくは２５ｗｔ％〜５０ｗｔ％である。 The cotton of the present embodiment is characterized by containing plant fiber kapok, animal fiber, and cellulose fiber, which are hygroscopic fibers, in a total mixing ratio of 20 wt% to 60 wt%. If the total mixing ratio is less than 20 wt%, the heat absorption and heat absorption, moisture absorption and desorption, and / or heat retention required for cotton are impaired. On the other hand, when the total mixing ratio exceeds 60 wt%, the mixing ratio of the synthetic fiber which is a hydrophobic fiber, for example, polyester fiber is lowered, so that the bulkiness and washing durability are remarkably lowered, and the wadding form is not maintained. Commerciality is lost. The total mixing ratio of the hygroscopic fibers, such as plant fiber kapok, animal fiber, and cellulose fiber, is preferably 25 wt% to 50 wt%.
本実施形態のわたには、カポック繊維が０．１ｗｔ％以上４０ｗｔ％以下の混率で含まれる必要がある。カポック繊維の混率が４０ｗｔ％を超えると、わた製品でのカポック繊維の脱落が多くなり、縫製時でのカポック繊維の飛散などで作業環境を悪化させることや、衣料製品の着用時や洗濯などでのカポック繊維の脱落により、わたとしての機能低下や、わたを縫い合わした衣料表面の外見が悪くなる。他方、０．１ｗｔ％未満では所望の効果が発現されない。カポック繊維の混率は、好ましくは１．０ｗｔ％以上３５ｗｔ％以下であり、より好ましくは１０ｗｔ％以上３０ｗｔ％以下である。 The cotton of the present embodiment needs to contain kapok fibers in a mixing ratio of 0.1 wt% or more and 40 wt% or less. If the mixing ratio of kapok fibers exceeds 40 wt%, the kapok fibers will fall off more often in the cotton products, which will worsen the working environment due to the scattering of the kapok fibers during sewing, and when wearing clothing products or washing. Due to the shedding of the Kapok fibers, the function of the wadding deteriorates and the appearance of the garment surface on which the wadding is sewn deteriorates. On the other hand, if it is less than 0.1 wt%, the desired effect is not exhibited. The mixing ratio of the kapok fibers is preferably 1.0 wt% or more and 35 wt% or less, and more preferably 10 wt% or more and 30 wt% or less.
本実施形態のわたには、吸湿性繊維として、カポック繊維以外に動物繊維が４０ｗｔ％以下の混率で含まれていてもよい。動物繊維としては、羊毛、アンゴラ、カシミヤなどが挙げられる。カポック繊維、セルロース繊維は、捲縮が少ないため、繊維同士が絡みにくく加工が難しいとされているが、動物繊維は捲縮性があるため絡みやすく、繊維がかさ高になり、かつ弾力性も出るためへたり性にも効果が得られる。動物繊維の混率が０．１ｗｔ％以上であることが好ましく、より好ましくは１．０ｗｔ％以上３０ｗｔ％以下である。 The cotton of the present embodiment may contain animal fibers in addition to kapok fibers at a mixing ratio of 40 wt% or less as hygroscopic fibers. Examples of animal fibers include wool, angora, and cashmere. Kapok fibers and cellulose fibers are said to be difficult to process because they have little crimping, so they are difficult to entangle with each other. Since it comes out, it is also effective for sagging. The mixing ratio of animal fibers is preferably 0.1 wt% or more, more preferably 1.0 wt% or more and 30 wt% or less.
