Abstract
Description
本発明は、羽毛成形体の製造方法に関する。 The present invention relates to a method for manufacturing a feather molded body.
水鳥等の羽毛は、低比重、柔軟性、嵩高性及び保湿性に優れていることから、寝具や衣料品に用いられている。一方、ブロイラーについては、それから排出される羽毛の大部分は焼却又は廃棄され、一部が肥料や飼料に利用されているに過ぎない。
近年、天然羽毛の特徴を生かした新規な素材の開発が試みられている。例えば、天然羽毛繊維と合成繊維を配合し、合成繊維の融点以上で熱処理して成形した天然羽毛繊維油吸着マット（特許文献１）や天然羽毛繊維断熱材（特許文献２）、また、羽毛と熱可塑性の接着剤とからなる羽毛集合体を、該接着剤によって圧縮接着した羽毛シート（特許文献３）や、羽毛と熱融着性繊維からウエブを形成し、バインダーによりそれを接着した羽毛シート（特許文献４）等、が報告されている。
Feathers such as waterfowl are used for bedding and clothing because of their low specific gravity, flexibility, bulkiness and moisture retention. On the other hand, with regard to broilers, most of the feathers discharged from it are incinerated or discarded, and only a part is used for fertilizer and feed.
In recent years, attempts have been made to develop new materials that take advantage of the characteristics of natural feathers. For example, natural feather fiber oil-absorbing mat (Patent Document 1), natural feather fiber heat insulating material (Patent Document 2), which is formed by blending natural feather fibers and synthetic fibers and heat-treating at or above the melting point of the synthetic fibers, A feather sheet obtained by compressing and bonding a feather assembly comprising a thermoplastic adhesive with the adhesive (Patent Document 3), or a feather sheet in which a web is formed from a feather and a heat-fusible fiber, and the binder is bonded to the feather sheet. (Patent Document 4) and the like have been reported.
特許文献１及び２の成形体は、天然羽毛を、脱脂洗浄して乾燥後、１０ｍｍ程度の長さの繊維状に切断加工して羽毛繊維とし、これを合成繊維（例えば、ＰＰ／ＰＥＴ芯鞘複合繊維）と均一に混合した後、所要の密度となるように積層し、熱風乾燥機にて熱成型して製造されるものである。
斯かる成形体は、天然羽毛を繊維状に切断加工して羽毛繊維とした後、合成繊維と混合して加熱処理されるものであり、羽毛を切断加工するという手間がかかり、さらに羽毛繊維と合成繊維を均一に混合することは容易ではない、という問題がある。
In the molded articles of Patent Documents 1 and 2, natural feathers are degreased, washed and dried, and then cut into fibers having a length of about 10 mm to form feather fibers, which are made of synthetic fibers (for example, PP / PET core sheath). After being uniformly mixed with the composite fiber), it is laminated so as to have a required density, and is thermoformed with a hot air dryer.
Such a molded body is obtained by cutting natural feathers into fibers to form feather fibers, which are then mixed with synthetic fibers and heat-treated, and it takes time and effort to cut the feathers. There is a problem that it is not easy to mix synthetic fibers uniformly.
また、特許文献３及び４の羽毛シートは、羽毛と特定の樹脂を融着成分とする熱融着性繊維とから、エアレイ法、乾式パルプ法などの不織布のウエブ形成法によりウエブを形成し、当該ウエブをバインダーにより接着して製造されるものである。
しかしながら、当該方法で製造されたシートは、厚さ３ミリ程度で、使用の際に加熱処理して嵩を回復させるものであり、その用途は限定されている。
However, the sheet manufactured by the method has a thickness of about 3 mm, and is heat-treated to recover the bulk during use, and its application is limited.
本発明は、軽量で、保温性、断熱性、防音性、遮音性、吸油性に優れるとともに、一定の機械的強度を有する羽毛成形体、及びその製造方法を提供することに関する。 The present invention relates to providing a feather molded body that is lightweight and has excellent heat retention, heat insulation, sound insulation, sound insulation, oil absorption, and a certain mechanical strength, and a method for producing the same.

When an aqueous emulsion resin, water and feathers are mixed and stirred, the resin is uniformly on the feather surface. It was found that an applied heat-fusible feather (resin-coated feather) was obtained, and a desired feather molded body could be produced by compression-heating molding.

From the viewpoint of effective utilization of resources, it is preferable to use feather bedding such as a down duvet, down clothing such as a down jacket, particularly recycled products of the above products and waste feathers from a manufacturing factory that cannot be reused.
本発明の羽毛成形体は、以下の工程（１）及び（２）を行うことにより製造することが出来る。
工程（１）は、水性エマルジョン樹脂、水及び羽毛を混合・撹拌して樹脂被覆羽毛を製造する工程である。
本工程は、ニーダー等の混合装置を用いて行われ、水性エマルジョン樹脂、水及び羽毛を混合、撹拌することにより行われるが、混合は、水と羽毛を混合させた状態で樹脂を添加すること、予め樹脂と水を混合させた樹脂溶液に羽毛を添加すること、或いは羽毛に、樹脂及び水を同時に添加して混合することの何れでもよい。
羽毛は、使用に際して、汚れた羽毛から、埃、泥、小石等の夾雑物を取り除いた後、洗剤、有機溶媒、水等を用いて洗浄し、羽毛に付着している泥、血液、肉片等の汚垢を除去することが行われるが、斯かる洗浄後の羽毛を、脱水・乾燥操作を行うことなく、そのまま本工程に使用することができる。
The feather molded object of this invention can be manufactured by performing the following processes (1) and (2).
Step (1) is a step of producing a resin-coated feather by mixing and stirring an aqueous emulsion resin, water and feathers.
This step is performed using a mixing device such as a kneader, and is performed by mixing and stirring an aqueous emulsion resin, water and feathers, but the mixing should be performed with the resin mixed with water and feathers. Either adding a feather to a resin solution in which a resin and water are mixed in advance, or adding a resin and water to the feather simultaneously and mixing them may be used.
When using feathers, remove dirt, mud, pebbles and other contaminants from dirty feathers, then wash with detergent, organic solvent, water, etc., and remove mud, blood, meat pieces, etc. attached to the feathers. The washed feathers can be used in this step as they are without performing dehydration and drying operations.
羽毛、水性エマルジョン樹脂及び水の混合比は、羽毛表面を樹脂で均一に被覆することができれば特に限定されないが、羽毛１００質量部に対して、樹脂は固形分で３〜５０質量部、好ましくは１５〜４０質量部、水は羽毛と樹脂が均一に混ざる量であればよく、例えば３００〜２０００質量部とすればよい。 The mixing ratio of feathers, water-based emulsion resin and water is not particularly limited as long as the feather surface can be uniformly coated with the resin, but the resin is 3 to 50 parts by mass, preferably 100 parts by mass of feathers, 15-40 mass parts and water should just be the quantity which a feather and resin mix uniformly, for example, should just be 300-2000 mass parts.
混合・攪拌は、常温〜５０℃で行うことができるが、コストの点から常温で行えばよい。混合・攪拌時間は、温度及び用いる樹脂の種類等によっても異なるが、通常０．５時間〜１時間行うことが好ましい。 Mixing and stirring can be performed at room temperature to 50 ° C., but may be performed at room temperature from the viewpoint of cost. The mixing / stirring time is preferably 0.5 hour to 1 hour, although it varies depending on the temperature and the type of resin used.
尚、本工程においては、必要に応じて、界面活性剤等を添加することができる。 In this step, a surfactant or the like can be added as necessary.
斯くして、羽毛表面が水性エマルジョン樹脂で均一に被覆された熱融着性の樹脂被覆羽毛が得られる。
当該樹脂被覆羽毛は、羽毛に比べて減容化されていることから、運搬や作業性に優れるという利点があり、本発明の羽毛成形体を製造するための製造中間体として有用である。
Thus, a heat-fusible resin-coated feather having a feather surface uniformly coated with an aqueous emulsion resin is obtained.
Since the resin-coated feather has a reduced volume compared to feathers, it has the advantage of being excellent in transportation and workability, and is useful as a production intermediate for producing the feather molded body of the present invention.
工程（２）は、工程（１）で得られた樹脂被覆羽毛を、圧縮加熱成形する工程である。すなわち、熱融着性の樹脂被覆羽毛を圧縮加熱して、点接着せしめる工程である。
圧縮加熱処理に当たり、樹脂の溶解性を促進や点接着の強度向上のために、必要に応じて、アルコール類、ケトン類、エーテル類、脂肪族炭化水素類、芳香族炭化水素類、ハロゲン化炭化水素類等の有機溶剤を樹脂被覆羽毛に噴霧して行うことができる。
Step (2) is a step of compression heating molding the resin-coated feather obtained in step (1). That is, it is a step of compressing and heating the heat-fusible resin-coated feather to make point adhesion.
During compression heat treatment, alcohols, ketones, ethers, aliphatic hydrocarbons, aromatic hydrocarbons, halogenated carbonization are used as necessary to promote resin solubility and improve the strength of point adhesion. An organic solvent such as hydrogen can be sprayed on the resin-coated feather.
圧縮加熱処理は、ホットプレスにより行うことができる。圧縮加熱の条件として、圧力は、樹脂被覆羽毛が点接着できる圧力であればよく、目的に応じて、１０〜５０ｋｇ／ｃｍ2で行えばよい。また、温度は１２０〜１７０℃が好ましく、１５０〜１６０℃がより好ましい。
所定温度での加圧時間は、温度に依存し高温になるほど短時間でよく、１５０℃で０．５時間以上、１２０℃で２時間以上が必要である。
尚、仕込む樹脂被覆羽毛の量を調節することにより、所望の空隙率を有する羽毛成形体を製造することが可能である。
The compression heat treatment can be performed by hot pressing. As a condition for compression heating, the pressure may be a pressure at which the resin-coated feather can be point-bonded, and may be 10 to 50 kg / cm 2 depending on the purpose. Moreover, 120-170 degreeC is preferable and 150-160 degreeC is more preferable.
The pressurization time at the predetermined temperature depends on the temperature and may be shorter as the temperature becomes higher. The pressurization time is 0.5 hours or more at 150 ° C. and 2 hours or more at 120 ° C.
In addition, it is possible to manufacture the feather molding which has a desired porosity by adjusting the quantity of the resin-coated feather to be charged.
具体的には、例えば、５０℃程度に加熱された金型に必要量を仕込み、型締め後、必要に応じてガス抜きを行い、２０〜５０ｋｇ／ｃｍ2で、０．５〜２時間加圧する方法が挙げられる。 Specifically, for example, a required amount is charged into a mold heated to about 50 ° C., and after clamping, the gas is vented as necessary, and is applied at 20-50 kg / cm 2 for 0.5-2 hours. The method to press is mentioned.
