Description
本発明は、吹き込み詰め物体用繊維綿とこれを使用した詰め物体及びその製造方法に関する。 The present invention relates to a fiber cotton for blow-stuffed objects, a stuffed object using the same, and a method for producing the same.
羽毛布団、羽毛ジャケットなどの羽毛製品に充填される羽毛は、一般的には水鳥の羽毛が使用されている。水鳥としてはグース（ガチョウ）、ダック（アヒル）、北極圏の海岸線に生息するアイダー（野生の鴨）などである。羽毛には、胸毛にあたるダウンと、羽根と呼ばれるフェザーがあり、ともに羽毛製品に使われている。羽毛の産地はポーランド、ハンガリーなどの中欧、スカンジナビア半島を含む北欧、中国などである。羽毛は、嵩高性に優れ、暖かく、掛け布団や羽毛ジャケットの羽毛製品として高級素材の地位を占めている。 The feathers used to fill feather products such as duvets and down jackets are generally waterfowl feathers. Waterfowl include geese, ducks, and eiders, which live on the coastlines of the Arctic Circle. Feathers include down, which is chest hair, and feathers, both of which are used in feather products. Feathers are produced in central Europe such as Poland and Hungary, Northern Europe including the Scandinavian Peninsula, and China. Feathers are bulky and warm, and have a status as a luxury material for comforters and down jackets.
しかし、天然の羽毛は水鳥に依存しており、その供給量には限度がある上、自然条件や厄病（例えば鳥ウィルス）の影響によって供給量も変動するという問題がある。あるいは自然保護の観点から、野生の鳥を捕捉することには限度がある。その上、天然の羽毛は、洗いが不充分であると悪臭の原因となるため、事前に悪臭の原因となる汚物を除去し、羽毛の洗浄の程度を見る清浄度と酸素計数を一定のレベルに保つ管理が必要である。加えて、羽毛布団、羽毛ジャケットなどの羽毛製品の洗濯は容易ではないという基本的な問題がある。 However, natural feathers depend on waterfowl, and there is a problem in that the supply amount is limited, and the supply amount fluctuates depending on natural conditions and the influence of harmful diseases (for example, bird viruses). Also, from the perspective of nature conservation, there are limits to capturing wild birds. In addition, natural feathers can cause bad odors if not washed sufficiently, so we remove dirt that causes bad odors in advance, and maintain the cleanliness and oxygen count to a certain level to check the degree of cleaning of the feathers. Management is required to keep it safe. In addition, there is a fundamental problem that down products such as duvets and down jackets are not easy to wash.
そこで、従来から詰め綿については多くの提案がある。本出願人は特許文献２～３において芯糸と花糸を交絡した詰め綿を提案している。特許文献３には芯糸に花糸を巻き付けて絡ませた詰め綿が提案されている。特許文献４には、糸長差を有する糸条を噴射気流により旋回させて嵩高加工することが提案されている。特許文献５には吹込み用綿状物が提案されている。 Therefore, there have been many proposals regarding stuffing cotton. In Patent Documents 2 and 3, the present applicant has proposed stuffed cotton in which core yarn and filament are intertwined. Patent Document 3 proposes stuffed cotton in which a filament is wound and entangled around a core thread. Patent Document 4 proposes that yarns having different yarn lengths are swirled by a jet air stream to be bulk-processed. Patent Document 5 proposes a cotton-like material for blowing.
しかし、前記従来の詰め綿は、吹込み用として好適ではものではなく、さらなる改良が求められていた。 However, the conventional stuffing cotton is not suitable for blowing, and further improvements have been required.
本発明は、上記問題を解決するため、吹込み用として好適な吹き込み詰め物体用繊維綿とこれを使用した詰め物体及びその製造方法を提供する。 In order to solve the above-mentioned problems, the present invention provides a fiber cotton for blow-stuffed objects suitable for blowing, a stuffed object using the same, and a method for manufacturing the same.

本発明の吹き込み詰め物体用繊維綿は、少なくとも２種類の繊維Ａ及び繊維Ｂで構成される吹き込み詰め物体用繊維綿であって、前記繊維Ａは前記繊維Ｂに比べて相対的に短く、前記繊維Ａ及び前記繊維Ｂは一体化されており、前記繊維綿は、１本又は複数本の前記一体化糸が集合した集合体であることにより、吹込み用として好適な吹き込み詰め物体用繊維綿とこれを使用した詰め物体及びその製造方法を提供できる。 The blown fiber cotton for stuffed objects of the present invention is a blown fiber cotton for blown stuffed objects that is composed of at least two types of fibers A and B, in which the fibers A are relatively shorter than the fibers B, and the fibers A are relatively shorter than the fibers B. The fibers A and the fibers B are integrated, and the fiber cotton is an aggregate of one or more of the integrated yarns, so that it is a fiber cotton for blow-filled objects suitable for blowing. A stuffed object using the same and a method for manufacturing the same can be provided.
本発明で使用する交絡糸は、少なくとも２種類の繊維Ａ及び繊維Ｂで構成される。繊維Ａ及び繊維Ｂ以外の繊維を加えることは任意であるが、一体化糸を１００質量％としたとき繊維Ａ及び繊維Ｂ合計で７０質量％以上が好ましく、より好ましくは８０質量％以上である。繊維Ａ及び繊維Ｂは一体化されている。ここで一体化とは、繊維同士が絡み合ったり、巻き付いたり、撚られた状態をいう。また、繊維Ａは繊維Ｂに比べて相対的に短い。繊維Ａと繊維Ｂとの長さの差を設けることでかさ高性を出している。繊維Ａ及び繊維Ｂは、所定の長さにカットされているので、カットされる前は長繊維Ａ及び長繊維Ｂという。 The interlaced yarn used in the present invention is composed of at least two types of fibers A and B. It is optional to add fibers other than fibers A and B, but when the integrated yarn is 100% by mass, the total amount of fibers A and B is preferably 70% by mass or more, more preferably 80% by mass or more. . Fiber A and fiber B are integrated. Here, "integration" refers to a state in which fibers are intertwined, wrapped, or twisted. Furthermore, fiber A is relatively shorter than fiber B. By providing a difference in length between fiber A and fiber B, bulkiness is achieved. Since the fibers A and B are cut into predetermined lengths, they are referred to as long fibers A and long fibers B before being cut.
本発明の吹き込み詰め物体用繊維綿は、１本又は複数本の前記一体化糸が集合した集合体である。集合体であると吹き込み可能となる。特に一体化糸が交絡糸である場合、詰め物体の耐洗濯性が良好であり、へたり難い利点がある。集合体の長さは平均３００ｍｍ以下が好ましく、さらに平均２００ｍｍ以下が好ましい。下限値は平均２０ｍｍ以上が好ましい。 The blown fiber cotton for stuffing objects of the present invention is an aggregate of one or more of the above-mentioned integrated yarns. If it is an aggregate, it can be injected. In particular, when the integrated yarn is an interlaced yarn, the stuffed object has good washing resistance and has the advantage of being resistant to fading. The length of the aggregate is preferably 300 mm or less on average, and more preferably 200 mm or less on average. The lower limit is preferably 20 mm or more on average.
前記集合体の質量は平均９～３６００ｍｇ／個が好ましく、より好ましくは平均１８～１８００ｍｇ／個であり、さらに好ましくは平均３０～１０００ｍｇ／個である。この質量であるとエアーブロー（空気流による充填）しやすく、掛け布団などの大きな側地にも均一に吹き込みやすくなる。 The mass of the aggregates is preferably 9 to 3,600 mg/piece on average, more preferably 18 to 1,800 mg/piece on average, and still more preferably 30 to 1,000 mg/piece on average. With this mass, air blowing (filling with air flow) is easy, and it becomes easy to evenly blow into large side fabrics such as comforters.
前記集合体は、１本又は複数本の交絡糸が折り曲げられるか巻き付けられ、少なくとも一か所接着又は融着により固定されていてもよい。これにより集合体は壊れにくくなる。接着又は融着は、接着テープもしくは融着テープを使用するか、又は交絡糸の中に熱融着繊維（例えば、ナイロン糸、低融点ポリエステル糸、ポリエチレン糸、ポリプロピレン糸）を混合しておき、熱処理、超音波処理、レーザービーム処理して融着させてもよい。接着テープもしくは融着テープとしては、スパンボンドなどの不織布テープ、ホットメルトフィルム、ポリオレフィン系、ポリエステル系、ポリウレタン系、ポリアミド系などを使用するのが好ましい。 In the aggregate, one or more intertwined threads may be bent or wound, and may be fixed by adhesion or fusion at at least one location. This makes the aggregate difficult to break. For adhesion or fusing, adhesive tape or fusion tape is used, or heat-fusible fibers (e.g., nylon thread, low-melting point polyester thread, polyethylene thread, polypropylene thread) are mixed in the intertwined thread. Fusion may be performed by heat treatment, ultrasonic treatment, or laser beam treatment. As the adhesive tape or fusion tape, it is preferable to use a nonwoven fabric tape such as spunbond, a hot melt film, a polyolefin type, a polyester type, a polyurethane type, a polyamide type, or the like.
繊維Ａ及び繊維Ｂから選ばれる少なくとも一部又は全部は再生ポリエステル繊維を使用するのが好ましい。好ましくは５～１００質量％が再生ポリエステル繊維であり、より好ましくは１０～１００質量％が再生ポリエステル繊維である。これにより、かさ高性が高く、環境配慮がなされた詰め物用糸が得られる。再生ポリエステル繊維はＰＥＴボトルを回収し、フレーク化し、乾燥し、溶融紡糸、延伸して得ることができる。回収ＰＥＴにバージンＰＥＴを混合してもよい。ボトル用ＰＥＴは数平均分子量がバージンＰＥＴ繊維（数平均分子量約２万）より高く、再生後でほぼバージンＰＥＴ繊維と同等の平均分子量になるとされているが、本発明の詰め物用糸は、かさ高性は高い。回収ＰＥＴをオリゴマーまで解重合し、再度重縮合した再生ポリエステルから紡糸した繊維でもよい。再生ポリエステルはリサイクルポリエステルともいう。 It is preferable to use recycled polyester fibers for at least some or all of the fibers A and B. Preferably 5 to 100% by weight is recycled polyester fiber, more preferably 10 to 100% by weight is recycled polyester fiber. This provides a stuffing yarn that is highly bulky and environmentally friendly. Recycled polyester fibers can be obtained by collecting PET bottles, flaking them, drying them, melt spinning them, and stretching them. Virgin PET may be mixed with recovered PET. PET for bottles has a higher number average molecular weight than virgin PET fiber (number average molecular weight of approximately 20,000), and is said to have an average molecular weight that is approximately the same as virgin PET fiber after recycling. High quality. Fibers spun from recycled polyester obtained by depolymerizing recovered PET to oligomers and polycondensing them again may be used. Recycled polyester is also called recycled polyester.
本発明の吹き込み詰め物体用繊維綿には、架橋剤として、少なくともウレタン系架橋剤、アクリル系架橋剤又はエポキシ樹脂架橋剤が付与されキュアリングにより固定されている。前記架橋剤を用いることによりかさ高性及び耐洗濯性を向上させることができる。さらに、表面処理剤として平滑性を向上させる樹脂平滑剤として、例えば、シリコーン系樹脂を前記架橋剤とともに併用するのが好ましい。特にシリコーン系樹脂剤とウレタン系架橋剤の併用が好ましい。 At least a urethane crosslinking agent, an acrylic crosslinking agent, or an epoxy resin crosslinking agent is applied as a crosslinking agent to the blown fiber cotton for stuffing objects of the present invention, and the crosslinking agent is fixed by curing. By using the crosslinking agent, bulkiness and washing resistance can be improved. Furthermore, as a surface treatment agent, it is preferable to use, for example, a silicone resin together with the crosslinking agent as a resin smoothing agent that improves smoothness. In particular, a combination of a silicone resin agent and a urethane crosslinking agent is preferred.
繊維Ａ及び繊維Ｂ以外の繊維は、ポリエステル、ナイロン、ポリプロピレンなどの繊維が使用できるが、好ましくはポリエチレンテレフタレート（ＰＥＴ）中空糸である。ポリエチレンテレフタレート中空糸は断熱効果により温かく、かつＰＥＴはコシがあり、かさ高性を高く維持できる。中空率は１０～４０％程度が好ましい。 As the fibers other than fiber A and fiber B, fibers such as polyester, nylon, and polypropylene can be used, but preferably polyethylene terephthalate (PET) hollow fibers are used. Polyethylene terephthalate hollow fibers are warm due to their insulation effect, and PET is stiff and can maintain high bulkiness. The hollow ratio is preferably about 10 to 40%.
長繊維一体化糸の単位長さ当たりの質量は０．０１～３ｇ／ｍが好ましく、０．０２～１．５ｇ／ｍがさらに好ましい。この範囲であると、詰め物加工にする際の取り扱いに便利である。 The mass per unit length of the long fiber integrated yarn is preferably 0.01 to 3 g/m, more preferably 0.02 to 1.5 g/m. Within this range, it is convenient to handle when processing stuffing.
長繊維一体化糸の繊維Ｂ(花糸）と繊維Ａ（芯糸）の重量比は、繊維Ｂ(花糸）と繊維Ａ（芯糸）を母数にしたとき、繊維Ｂ(花糸）の割合は５１～９９質量％（ｗｔ％）の範囲が好ましい。更に好ましくは８０～９８ｗｔ％の範囲、特に好ましくは８５～９７ｗｔ％の範囲である。前記範囲であれば、繊維Ａ（芯糸）による固定一体化はしっかりしたものとなり、かつ風合いも良好となる。 The weight ratio of fiber B (filament) and fiber A (core thread) of long fiber integrated yarn is, when fiber B (filament) and fiber A (core thread) are used as parameters, fiber B (filament) The ratio is preferably in the range of 51 to 99% by mass (wt%). More preferably, it is in the range of 80 to 98 wt%, particularly preferably in the range of 85 to 97 wt%. Within the above range, the fixation and integration by the fibers A (core yarn) will be firm and the texture will be good.
カットする前の長繊維Ａ及び長繊維Ｂは、交絡加工、エアージェット加工、巻き付け加工、撚り加工及び長繊維Ａに対して長繊維Ｂを噴射させる加工から選ばれる少なくとも一つの加工により一体化されているのが好ましい。交絡加工は長繊維Ａと長繊維Ｂの走行方向に対して垂直方向に圧空を噴射するエアー交絡機による加工である。エアージェット加工はいわゆるタスラン加工であり、長繊維Ａと長繊維Ｂに対して進行方向に圧空を押し込む加工である。巻き付け加工は長繊維Ａに対して長繊維Ｂを巻き付け、一体化する加工である。撚り加工は長繊維Ａと長繊維Ｂとを実撚り又は仮撚りする加工である。長繊維Ａに対して長繊維Ｂを噴射させる加工は、長繊維Ａに長繊維Ｂを噴射させ絡めるか又は旋回させる加工である。 The long fibers A and the long fibers B before being cut are integrated by at least one process selected from entangling processing, air jet processing, winding processing, twisting processing, and a process of injecting the long fibers B onto the long fibers A. It is preferable that The entangling process is a process using an air entangling machine that injects compressed air in a direction perpendicular to the running direction of the long fibers A and B. The air jet processing is a so-called Taslan processing, and is a processing in which compressed air is forced into the long fibers A and B in the traveling direction. The winding process is a process in which long fibers B are wound around long fibers A to integrate them. The twisting process is a process of actually twisting or false twisting the long fibers A and B. The process of injecting the long fibers B onto the long fibers A is a process in which the long fibers B are injected onto the long fibers A and are entangled or swirled.
長繊維一体化糸は、シリコーン樹脂が付与されキュアリングにより熱固定されているのが好ましい。シリコーン樹脂の好ましい付着量は、詰め物用糸に対して０．１～１０質量％の範囲である。さらに、硬さ調整のためアクリル系樹脂、ウレタン系樹脂、エポキシ系樹脂などを固定しても良い。 The long fiber integrated yarn is preferably coated with a silicone resin and heat-set by curing. The preferred amount of silicone resin deposited is in the range of 0.1 to 10% by mass based on the stuffing yarn. Furthermore, acrylic resin, urethane resin, epoxy resin, etc. may be fixed to adjust the hardness.
前記繊維Ｂは、ポリエステル中空糸またはポリエステル異形断面糸であってもよい。もちろん通常の中実糸であってもよい。 The fibers B may be polyester hollow fibers or polyester irregular cross-section fibers. Of course, ordinary solid yarn may be used.
本発明の詰め物体は、前記繊維綿が側地に吹き込まれ、充填された詰め物体である。前記繊維綿は、１本又は複数本の前記一体化糸が集合した集合体であり、この集合体のまま側地内に吹き込まれており、前記繊維綿は様々な方向に配列されている。前記繊維綿は集合体であることにより側地に吹き込みやすく、かつ詰め物体の耐洗濯性は向上し、へたり難い。 The stuffed object of the present invention is a stuffed object in which the above-mentioned fiber cotton is blown into the side fabric and filled. The fiber cotton is an aggregate of one or more of the integrated yarns, and this aggregate is blown into the side fabric, and the fiber cotton is arranged in various directions. Since the fiber cotton is an aggregate, it is easy to blow into the side fabric, and the washing resistance of the stuffed object is improved, and it is difficult to set.
本発明の詰め物用糸は、一例として、布団、毛布、寝袋、枕、クッション、マット、ぬいぐるみ、ひざ掛け、ジャケット、シャツ、パンツ、ベスト、コート、防寒衣料、作業着及びネックウォーマーから選ばれる少なくとも一つの詰め物体に充填されている。ジャケット、シャツ、パンツなどの衣類はスポーツ用に好適である。また、インナージャケットのようなフィット感があり、良く伸びる性質がある。 The stuffing yarn of the present invention can be used, for example, at least one material selected from futons, blankets, sleeping bags, pillows, cushions, mats, stuffed animals, throws, jackets, shirts, pants, vests, coats, winter clothing, work clothes, and neck warmers. It is filled into two filling objects. Clothing such as jackets, shirts, and pants are suitable for sports. It also fits like an inner jacket and stretches well.
本発明の詰め物体は、前記繊維綿を５０質量％以上含むのが好ましく、さらに好ましくは７０質量％以上が好ましい。５０質量％以下の範囲で羽毛、人工羽毛、繊維綿などと併用してもよい。羽毛、人工羽毛、繊維綿なども同時吹き込みが可能である。 The stuffed object of the present invention preferably contains the fiber cotton in an amount of 50% by mass or more, more preferably 70% by mass or more. It may be used in combination with feathers, artificial feathers, fiber cotton, etc. within a range of 50% by mass or less. Feathers, artificial feathers, fiber cotton, etc. can also be blown at the same time.
繊維Ａ及び繊維Ｂの単繊維繊度は０．１～３００decitex、かつトータル繊度が１０～６００decitexの範囲が好ましい。更に好ましくは単繊維繊度が１．０～５０decitex、かつトータル繊度が１５～２５０decitexの範囲である。繊度が前記の範囲であれば、へたりにくく、かつ風合いも良好である。 The single fiber fineness of fibers A and B is preferably in the range of 0.1 to 300 decitex, and the total fineness is in the range of 10 to 600 decitex. More preferably, the single fiber fineness is in the range of 1.0 to 50 decitex, and the total fineness is in the range of 15 to 250 decitex. If the fineness is within the above range, it will not easily sag and will have a good texture.
本発明の詰め物体の製造方法は、前記繊維綿を側地に吹き込む際に吹込み機を用いる。吹込み機に特に制限はないが、好ましくはブロワーを通過せずに側地に吹き込むエジェクター方式である。前記エジェクター方式吹込み機のブロワーは、前記繊維綿の供給領域と側地との中間部に配置され、前記繊維綿は供給領域から前記ブロワ―の吸引流体と前記ブロワーからの噴射流体により側地に吹き込まれる。これにより、繊維綿がブロワーに絡まずスムースに側地に吹き込める。従来のブロワーを通過する吹き込み機を用いたのでは、繊維綿がブロワーに絡まってしまう可能性が高い。また、従来のポリエステルなどの合成繊維、コットン、ウールなどの短繊維を吹き込む真空充填装置も知られているが、この装置は大掛かりな制御装置が必要で、かつ掛け布団のようなかさ高な詰め物体を作成することが困難である。 In the method for manufacturing a stuffed object of the present invention, a blowing machine is used when blowing the fiber cotton into the side fabric. There are no particular restrictions on the blowing device, but preferably an ejector type that blows into the side area without passing through a blower. The blower of the ejector-type blowing machine is disposed at an intermediate portion between the fiber cotton supply area and the side fabric, and the fiber cotton is transferred from the supply area to the side fabric by the suction fluid of the blower and the jetted fluid from the blower. is blown into. This allows the fiber cotton to smoothly blow into the side fabric without getting tangled with the blower. When using a conventional blower that passes through a blower, there is a high possibility that the cotton fibers will become tangled in the blower. In addition, conventional vacuum filling equipment that infuses synthetic fibers such as polyester, short fibers such as cotton, and wool is also known, but this equipment requires a large-scale control device and cannot handle bulky stuffed objects such as comforters. It is difficult to create.
以下図面を用いて説明する。各図面において、同一符号は同一部分を示す。図１は本発明の一実施形態で使用する長繊維交絡糸の模式的側面図である。この長繊維交絡糸１は、芯糸２（長繊維Ａ）と花糸３（長繊維Ｂ）の構成繊維が互いに絡まっており、花糸３が開繊されて部分的にループ状繊維を形成している。 This will be explained below using the drawings. In each drawing, the same reference numerals indicate the same parts. FIG. 1 is a schematic side view of a long fiber entangled yarn used in an embodiment of the present invention. In this intertwined long fiber yarn 1, the constituent fibers of the core yarn 2 (long fiber A) and filament yarn 3 (long fiber B) are entangled with each other, and the filament yarn 3 is opened to partially form loop-shaped fibers. are doing.
図２はエアー交絡糸の製造方法を示す模式的説明図である。巻き糸体４から芯糸４ａ（長繊維Ａ）を引き出し、巻き糸体５から花糸５ａ（長繊維Ｂ）引き出し、２個のフィードローラ６、７と糸ガイド８を通過させてエアー交絡装置１０に供給する。エアー交絡装置１０に圧力空気１１を供給すると、糸道９内の繊維は開繊されたり旋回されることにより、互いに交絡する。１２は混繊交絡糸である。芯糸の供給速度は１０～２００ｍ／分、花糸の供給速度は２０～１００００ｍ／分、巻き取り速度１０～２００ｍ／分、空気圧力０．０１～１．０ＭＰａの交絡ノズルで混繊交絡処理を施した後、デリベリローラ１３通過後の糸を巻き糸体２０に巻き取る。この方法は、糸の巻き取り速度を２０～１５００ｍ／分と高速化でき、生産性が高いところに利点がある。 FIG. 2 is a schematic explanatory diagram showing a method for producing air-entangled yarn. The core thread 4a (long fiber A) is pulled out from the thread body 4, the filament 5a (long fiber B) is drawn out from the thread body 5, and passed through two feed rollers 6, 7 and a thread guide 8 to form an air entangling device. Supply to 10. When pressurized air 11 is supplied to the air entangling device 10, the fibers in the yarn path 9 are opened or swirled, thereby becoming entangled with each other. 12 is a mixed fiber entangled yarn. The core thread supply speed is 10 to 200 m/min, the filament supply speed is 20 to 10,000 m/min, the winding speed is 10 to 200 m/min, and the fibers are mixed and entangled using an interlacing nozzle with an air pressure of 0.01 to 1.0 MPa. After passing through the delivery roller 13, the thread is wound onto a winding thread body 20. This method has the advantage that the yarn winding speed can be increased to 20 to 1500 m/min, and productivity is high.
得られた交絡糸は、シリコーン樹脂を付与する。シリコーン樹脂としては、分子末端がハイドロジェン基（－ＯＨ）、ビニル基（－ＣＨ＝ＣＨ2）などを有する反応性シリコーン処理剤を使用するのが好ましい。例えば、松本油脂製薬社製“ＴＥＲＯＮ Ｅ ５３０”バルキーシリコン、“ＴＥＲＯＮ Ｅ ７３１”、“ＴＥＲＯＮ Ｅ ７２２”などのソフトシリコンを使用できる。付与量は、乾燥重量で詰め綿に対し０．１～１０質量％付与するのが好ましい。次に熱処理工程において、１４０～１９０℃で１～１０分間熱処理し、シリコーン樹脂をキュアリングする。このとき、芯糸の潜在捲縮型ストレッチ糸は後捲縮が発現する。 The resulting interlaced yarn is coated with silicone resin. As the silicone resin, it is preferable to use a reactive silicone treatment agent having a hydrogen group (-OH), a vinyl group (-CH=CH 2 ), etc. at the molecular end. For example, soft silicones such as "TERON E 530" bulky silicone, "TERON E 731", and "TERON E 722" manufactured by Matsumoto Yushi Pharmaceutical Co., Ltd. can be used. The amount applied is preferably 0.1 to 10% by weight based on the dry weight of the stuffed cotton. Next, in a heat treatment step, the silicone resin is cured by heat treatment at 140 to 190° C. for 1 to 10 minutes. At this time, the latent crimp type stretch yarn of the core yarn develops rear crimp.

（６）図３Ｆは一体化糸２２を円筒状の接着テープ２３の外側に、円筒の長さ方向に配列するようにジグザク状に配列したものである。接着テープ２３の内側には支持体を入れて、後に取り去る。このようにして得られたものをスパイラル状＋外リング型繊維綿２８と呼ぶ。
（７）図３Ｇは交絡糸２２を折りたたんで繊維束とし、外側から接着テープ２３で固定したものである。これをスネーク状＋外リング型繊維綿２９と呼ぶ。
FIGS. 3A-3G are schematic side views of a fiber cotton for blow-stuffing objects in one embodiment of the present invention. Various types of cotton fibers can be used, including, but not limited to, the following, by way of example:
(1) In Fig. 3A, the intertwined thread 22 is formed like a feather, and the integrated thread 22 is bent into multiple pairs and an adhesive tape 23 is pasted in the longitudinal direction of the center to fix the integrated thread 22. ing. The size of this feather type fiber cotton 21 is, for example, 15 cm or less in length and 8 cm or less in width.
(2) In FIG. 3B, the interlaced yarn 22 is wound in a spiral shape, and the integrated yarn 22 is fixed by pasting adhesive tape 23 on the outside or inside. This is called spiral type fiber cotton 24.
(3) In FIG. 3C, the intertwined yarn 22 is bent in a zigzag shape, and an adhesive tape 23 is attached in the longitudinal direction at the center to fix the integrated yarn 22. This is called snake-type fiber cotton 25.
(4) In FIG. 3D, the intertwined threads 22 are arranged in a plurality of straight rows, and the integrated threads 22 are fixed by pasting adhesive tape 23 on both ends. This is called straight type double-sided fixed fiber cotton 26.
(5) FIG. 3E shows the straight type double-sided fixed fiber cotton 26 of FIG. 3D cut at an arbitrary point in the center. This is called straight type one side fixed fiber cotton 27.
(6) In FIG. 3F, the integrated threads 22 are arranged in a zigzag pattern on the outside of the cylindrical adhesive tape 23 in the longitudinal direction of the cylinder. A support is placed inside the adhesive tape 23 and removed afterwards. The product thus obtained is called spiral + outer ring type fiber cotton 28.
(7) In FIG. 3G, the interlaced yarn 22 is folded into a fiber bundle, which is fixed from the outside with an adhesive tape 23. This is called snake-shaped + outer ring type fiber cotton 29.
図４は本発明の一実施形態における吹き込み詰め物体用繊維綿を製造するための模式的側面図である。円筒形支持体３０の外側表面に一体化糸２２を複数回巻き付け、外側から接着テープ２３で固定する。この状態で円筒形支持体３０を取り去ると図３Ｂのスパイラル型繊維綿２４が作成できる。また、接着テープ２３を縦方向にカットすると図３Ｄのストレート型両側固定繊維綿２６が作成できる。 FIG. 4 is a schematic side view for manufacturing fiber cotton for blow-stuffed objects in one embodiment of the present invention. The integrated thread 22 is wound multiple times around the outer surface of the cylindrical support 30 and fixed from the outside with an adhesive tape 23. When the cylindrical support 30 is removed in this state, the spiral-wound fiber cotton 24 shown in FIG. 3B can be produced. Further, by cutting the adhesive tape 23 in the longitudinal direction, a straight type double-sided fixed fiber cotton 26 as shown in FIG. 3D can be created.
図５は本発明の一実施形態における吹込み装置３１の模式的説明図である。この吹込み装置３１は、ブロワー３２と、吸引口３３と、吹き出し口３４を含む。吸引口３３と吹き出し口３４の中間部３７において、吸引口３３は、ブロワー３２と中間部３７との接続部３８より吹き出し口３４側に突出させてあり、これによりブロワー３２からの噴射空気流は矢印３５ａ，３５ｂ，３５ｃのように流れる。また吸引空気流は３５ｄのように流れる。その結果、繊維綿３６ａ，３６ｂはブロワー３２を通過せずに吸引口３３から吹き出し口３４に送られ、側地内に吹き込まれる。よって、繊維綿３６ａ，３６ｂはブロワー３２内で絡みつくことはない。 FIG. 5 is a schematic explanatory diagram of the blowing device 31 in one embodiment of the present invention. This blowing device 31 includes a blower 32 , a suction port 33 , and a blowout port 34 . At the intermediate portion 37 between the suction port 33 and the air outlet 34, the suction port 33 projects toward the air outlet 34 from the connecting portion 38 between the blower 32 and the intermediate portion 37, so that the air flow ejected from the blower 32 is It flows as shown by arrows 35a, 35b, and 35c. Further, the suction air flow flows as shown in 35d. As a result, the cotton fibers 36a and 36b are sent from the suction port 33 to the blowout port 34 without passing through the blower 32, and are blown into the side fabric. Therefore, the cotton fibers 36a and 36b do not become entangled within the blower 32.
図６Ａ－Ｃは比較例における吹込み装置４４の模式的説明図である。この吹込み装置４４は、ブロワー４３と、吸引口３９と、吹き出し口４０を含み、吸引空気流は４１ｅで吸引された繊維綿４２ａはブロワー４３内の空気流４２ｂに随伴し、噴射流４１ｃ，４１ｄにより側地内に吹き込まれる。繊維綿４２ａはブロワー４３内を通過する際に、スクロール４５とライナー４６との間を通過することから、繊維綿４２ｂはブロワー４３内に絡みつきやすくなる。ライナー４６はモーター４７によって回転され、送風を引き起こす。 FIGS. 6A to 6C are schematic illustrations of the blowing device 44 in a comparative example. This blowing device 44 includes a blower 43, a suction port 39, and a blowout port 40, and the fiber cotton 42a sucked by the suction air flow 41e accompanies the air flow 42b inside the blower 43, and the jet flow 41c, 41d into the side land. Since the cotton fibers 42a pass between the scroll 45 and the liner 46 when passing through the blower 43, the cotton fibers 42b tend to become entangled in the blower 43. The liner 46 is rotated by a motor 47 to cause air blowing.
以下実施例により、本発明をさらに具体的に説明する。なお本発明は下記の実施例に限定されるものではない。 The present invention will be explained in more detail below with reference to Examples. Note that the present invention is not limited to the following examples.

When long fibers B and long fibers A are used as parameters, long fibers B were supplied at a ratio of 51 to 99% by mass.
次に表面処理工程において、ウレタン樹脂架橋剤として日華化学社製樹脂、５質量％、シリコーン系樹脂剤として松本油脂製薬社製“テロン Ｅ－５３０”を０．５％質量％の水溶液を使用し、付与量は乾燥重量で詰め綿に対し１．５～３．５質量％散布した。次に熱処理工程において、１４０～１９０℃で１～１３分間熱処理し、シリコーン樹脂を熱キュアリング固定した。 Next, in the surface treatment step, an aqueous solution of 5% by mass of resin manufactured by Nicca Chemical Co., Ltd. as a urethane resin crosslinking agent and 0.5% by mass of "Teron E-530" manufactured by Matsumoto Yushi Pharmaceutical Co., Ltd. as a silicone resin agent was used. The applied amount was 1.5 to 3.5% by mass of the stuffed cotton on a dry weight basis. Next, in the heat treatment step, heat treatment was performed at 140 to 190°C for 1 to 13 minutes to fix the silicone resin by heat curing.
得られた表面処理交絡糸を１５本束ね、図４に示すように直径３０ｍｍの紙管に４回転巻き、熱融着不織布で押さえた。得られた繊維綿の質量は平均７００mg／個であった。 Fifteen of the obtained surface-treated entangled yarns were bundled, wound four times around a paper tube having a diameter of 30 mm as shown in FIG. 4, and pressed with a heat-sealable nonwoven fabric. The average mass of the obtained cotton fibers was 700 mg/piece.
図５に示す吹込み装置を使用し、得られた繊維綿を側地内に吹き込んだ。側地は座布団側地用コットン生地であり、サイズはタテ２００ｍｍ、ヨコ２００ｍｍ、質量１０ｇであった。吹き込んだ繊維綿は１０ｇであった。繊維綿は側地内に均一に充填されていた。 Using the blowing device shown in FIG. 5, the obtained cotton fibers were blown into the side fabric. The side fabric was made of cotton fabric for cushion side fabric, and the size was 200 mm in length, 200 mm in width, and 10 g in weight. The amount of blown fiber cotton was 10 g. The fiber cotton was uniformly filled in the side fabric.
このようにして得られた座布団を２２リットルの家庭用洗濯機で８分間洗濯し、２回すすぎ、６分脱水した後にそれぞれ乾燥（部屋干し）し、評価した。 The cushions thus obtained were washed in a 22 liter household washing machine for 8 minutes, rinsed twice, dehydrated for 6 minutes, dried (room-dried), and evaluated.
（比較例１）
実施例１の交絡糸１５本束を並列に並べ、長さ２００ｍｍ、幅２００ｍｍにしてカット両端部を熱融着不織布で抑えた。この長繊維綿をタテ２００ｍｍ、ヨコ２００ｍｍ、質量１０ｇの座布団側地用コットン生地に充填した。
(Comparative example 1)
A bundle of 15 intertwined yarns of Example 1 was arranged in parallel to have a length of 200 mm and a width of 200 mm, and both ends of the cut were held down with a heat-sealable nonwoven fabric. This long-staple cotton was filled into a cotton fabric for the side of a cushion having a length of 200 mm, a width of 200 mm, and a mass of 10 g.
このようにして得られた座布団を２２リットルの家庭用洗濯機で８分間洗濯し、２回すすぎ、６分脱水した後にそれぞれ乾燥し、評価した。 The cushions thus obtained were washed in a 22 liter domestic washing machine for 8 minutes, rinsed twice, dehydrated for 6 minutes, dried and evaluated.
実施例１と比較例１の座布団の洗濯試験の結果を下記表１にまとめて示す。表１の平均高さは、本素材を入れたミニ座布団の上に発泡スチロール板を乗せてその４つ角の高さを測定し、その平均値を記入した。また、平均高さの増減率は、洗濯前を基準としたときの増減率を示す。 The results of the washing test for the cushions of Example 1 and Comparative Example 1 are summarized in Table 1 below. For the average height in Table 1, a Styrofoam board was placed on top of the mini cushion containing this material, the heights of the four corners were measured, and the average value was recorded. Moreover, the rate of increase/decrease in average height indicates the rate of increase/decrease based on before washing.
表１から明らかなとおり、実施例１は比較例１とほぼ同等の耐洗濯性を示した。比較例１は長繊維中綿を使用し、両端を固定しているので、中綿の移動が少なく、耐洗濯性はもともと優れているが、繊維綿を吹き込んだ実施例１は比較例１とほぼ同等の耐洗濯性を示した。 As is clear from Table 1, Example 1 showed almost the same washing resistance as Comparative Example 1. Comparative Example 1 uses long fiber filling and has both ends fixed, so there is less movement of the filling and the washing resistance is originally excellent, but Example 1, in which fiber cotton is blown, is almost equivalent to Comparative Example 1. showed washing resistance.
