Description
本発明は、特定の油脂を含有するレーヨン繊維、その製造方法及び繊維構造物に関する。 The present invention relates to a rayon fiber containing a specific fat and oil, a method for producing the same, and a fiber structure.
再生セルロースを用いたレーヨン繊維は、例えばビスコース法、銅アンモニア法、溶剤紡糸法等様々な方法で製造されることが知られている。レーヨン繊維は基質がセルロースであるため、それ自体肌に優しい性質を有する。従来から、上記レーヨン繊維の性質をさらに発揮させるため、様々な提案がされている。例えば、脂肪酸（油脂分）を練り込んだ再生セルロース繊維に関する提案として、オレイン酸又はオレイン酸の金属塩を練り込む提案（特許文献１）、γ−リノレン酸乳化液を練り込む提案（特許文献２〜３）、ドコサヘキサエン酸（ＤＨＡ）乳化液を練り込む提案（特許文献４）、γ−リノレン酸の乳化物を練り込む提案（特許文献５）、オレイン酸又はその塩を練り込み、セル状領域を形成したレーヨン繊維の提案（特許文献６）、脂肪酸又はその塩と脂溶性の酸化防止剤を練り込み、セル状領域を形成したレーヨン繊維の提案（特許文献７）、こめ油、γ−オリザノール、フェルラ酸を含む乳化液を練り込む提案（特許文献８）、オリーブオイル乳化液を練り込む提案（特許文献９）、相変化材料をマイクロカプセルに封入して添加したセルロース系繊維の提案（特許文献１０）等がある。また、特許文献１１には、スクワラン等の油分を含むレーヨン繊維等の含油繊維を原料繊維として用いた化粧・美容用不織布が提案されている。 It is known that rayon fibers using regenerated cellulose are produced by various methods such as a viscose method, a copper ammonia method, and a solvent spinning method. Since rayon fiber is made of cellulose as a substrate, it itself has a gentle nature to the skin. Conventionally, various proposals have been made to further exhibit the properties of the rayon fiber. For example, as proposals regarding regenerated cellulose fibers kneaded with fatty acids (oils and fats), proposals for kneading oleic acid or metal salts of oleic acid (Patent Document 1), proposals for kneading γ-linolenic acid emulsion (Patent Document 2) -3), proposal to knead docosahexaenoic acid (DHA) emulsion (Patent Document 4), proposal to knead emulsion of γ-linolenic acid (Patent Document 5), knead oleic acid or salt thereof, cellular region Proposal of Rayon Fiber (Patent Document 6) Formed with Cation, Proposal of Rayon Fiber Formed with Cellulose Region by Kneading Fatty Acid or its Salt and Fat-soluble Antioxidant (Patent Document 7), Rice Oil, γ-Oryzanol , A proposal to knead an emulsion containing ferulic acid (Patent Document 8), a proposal to knead an olive oil emulsion (Patent Document 9), and added a phase change material enclosed in a microcapsule Proposal of cellulose fibers (Patent Document 10), and the like. Patent Document 11 proposes a non-woven fabric for cosmetics and beauty using oil-containing fibers such as rayon fibers containing oil such as squalane as raw material fibers.
特許文献１〜７で用いている脂肪酸は融点が１４℃以下であるために常温で液体であり、容易に乳化することが可能である。また、特許文献８で用いているこめ油及び特許文献９で用いているオリーブオイルも不飽和脂肪酸を多く含むために低融点であり、容易に乳化可能である。特許文献１０では、油脂あるいは脂肪酸をマイクロカプセル化して添加している。特許文献１１で油分として用いているスクワランは、常温で液体であり、容易に乳化することが可能である。 Since the fatty acid used in Patent Documents 1 to 7 has a melting point of 14 ° C. or lower, it is liquid at room temperature and can be easily emulsified. In addition, the rice oil used in Patent Document 8 and the olive oil used in Patent Document 9 contain a large amount of unsaturated fatty acids, so have a low melting point and can be easily emulsified. In Patent Document 10, fats and oils or fatty acids are added as microcapsules. Squalane used as an oil component in Patent Document 11 is liquid at room temperature and can be easily emulsified.
上述したように、２０℃以下で液体（融点が２０℃以下）の油脂は、流動性が高く、肌になじみやすい性質を有し、乳化は比較的容易である。しかしながら、２０℃以下で液体の油脂は二重結合を含む不飽和脂肪酸の含有量が多く、酸化が生じやすい。そのため、２０℃以下で液体の油脂を繊維中に含有させる場合には、油脂の酸化を防止する必要がある。そこで、油脂の酸化を防止するため、油脂に酸化防止剤を添加する技術が提案されている。例えば、特許文献２〜５では、酸化防止剤として３，５−ジ−ブチルヒドロキシトルエン、イオウ系酸化防止剤、トコフェロール類を脂肪酸と併用することが開示されている。また、油脂としてこめ油を用いている特許文献８では、フェルラ酸を０．５〜２重量％含有させること、特許文献７では脂溶性の酸化防止剤を脂肪酸に含有させることが提案されている。 As described above, oils and fats that are liquid at 20 ° C. or lower (melting point: 20 ° C. or lower) have high fluidity and are easy to adjust to the skin, and are relatively easy to emulsify. However, liquid fats and oils at 20 ° C. or less have a high content of unsaturated fatty acids containing double bonds, and are likely to be oxidized. Therefore, when liquid fats and oils are contained in the fiber at 20 ° C. or lower, it is necessary to prevent the fats and oils from being oxidized. Therefore, in order to prevent the oxidation of fats and oils, a technique for adding an antioxidant to the fats and oils has been proposed. For example, Patent Documents 2 to 5 disclose that 3,5-di-butylhydroxytoluene, a sulfur-based antioxidant, and tocopherols are used in combination with a fatty acid as an antioxidant. Further, in Patent Document 8 using rice bran oil as an oil and fat, it is proposed that 0.5 to 2% by weight of ferulic acid is contained, and in Patent Document 7 that a fat-soluble antioxidant is contained in a fatty acid. .
しかしながら、例えば、２０℃以下で液体の油脂を酸化防止剤とともにビスコース中に乳化して添加しようとすると十分に微細なエマルジョン化が困難であった。 However, for example, if an attempt is made to emulsify liquid oil and fat together with an antioxidant in viscose at 20 ° C. or less, it is difficult to make a sufficiently fine emulsion.
本発明は、従来の問題を解決するため、融点が２０℃以下の油脂を酸化安定性が良好な状態でレーヨン繊維を構成するセルロース内に微分散させた油脂含有レーヨン繊維、その製造方法及び繊維構造物を提供する。 In order to solve the conventional problems, the present invention provides a fat-containing rayon fiber in which a fat having a melting point of 20 ° C. or less is finely dispersed in cellulose constituting the rayon fiber in a state of good oxidation stability, a method for producing the same, and a fiber Provide a structure.

Examples of the glycerin esters of the fatty acids include saturated fatty acid glycerin esters, saturated fatty acid mixed glycerin esters, unsaturated fatty acid glycerin esters, and unsaturated fatty acid mixed glycerin esters. And mixed glycerin ester of saturated fatty acid and unsaturated fatty acid. In general, when the number of carbon atoms increases, the melting point of the fatty acid increases. When the number of carbon atoms is the same, the melting point of the unsaturated fatty acid tends to be lower than that of the saturated fatty acid. It contains a fatty acid component, and many of naturally occurring oils and fats that are liquid at 20 ° C. have a melting point of 20 ° C. or less, and are more fluid than normal oils and fats at room temperature, giving an effect that is easy to adjust to the skin. it can. In the present invention, the oil that is liquid at 20 ° C. means that the melting point of the oil is 20 ° C. or less.
本発明に用いられる油脂に含まれる脂肪酸成分は、飽和脂肪酸、不飽和脂肪酸及びそれらのグリセリンエステルのいずれであってもよい。脂肪酸の炭素数としては、特に限定されないが、例えば、炭素数１６〜２２であることが好ましい。上記不飽和脂肪酸としては、パルミトレイン酸、オレイン酸、リノール酸、リノレン酸、エイコセン酸、エルシン酸等から選ばれる少なくとも１種を含むことが好ましい。上記飽和脂肪酸としては、パルミチン酸、ステアリン酸、アラキジン酸、ペヘニン酸等から選ばれる少なくとも１種を含むことが好ましい。 The fatty acid component contained in the fats and oils used in the present invention may be any of saturated fatty acids, unsaturated fatty acids, and glycerin esters thereof. Although it does not specifically limit as carbon number of a fatty acid, For example, it is preferable that it is C16-22. The unsaturated fatty acid preferably contains at least one selected from palmitoleic acid, oleic acid, linoleic acid, linolenic acid, eicosenoic acid, erucic acid and the like. The saturated fatty acid preferably contains at least one selected from palmitic acid, stearic acid, arachidic acid, pehenic acid and the like.

This texture will be described in detail. When the oil-containing rayon fiber of the present invention is used, the surface has a slimy feeling and a soft texture is expressed when it is made into a fiber structure as compared with the conventional rayon fiber. The product has a gentle texture and can produce a very high-class effect on the product (hereinafter also referred to as the texture effect). In addition, since the fat and oil-containing rayon fiber of the present invention is kneaded with fats and oils in the fiber, the texture effect of the present invention is a so-called post-processing finish that imparts a softener at the final finishing stage of a conventional fiber structure. Compared with outstanding washing durability.
本発明の繊維構造物として、例えば、紡績糸とした場合、上記油脂含有レーヨン繊維単独、又はその他の再生セルロース繊維、コットン、麻、ウール、アクリル、ポリエステル、ポリアミド、ポリオレフィン、ポリウレタン等の他の繊維と混紡、複合することが好ましい。このような紡績糸は、例えば織物や編物に加工されて衣料等に用いることができる。 As the fiber structure of the present invention, for example, in the case of a spun yarn, the above oil-containing rayon fiber alone or other regenerated cellulose fibers, cotton, hemp, wool, acrylic, polyester, polyamide, polyolefin, polyurethane, and other fibers It is preferable to be blended with and mixed with. Such spun yarn can be processed into a woven fabric or a knitted fabric and used for clothing or the like.
本発明の繊維構造物として、織物や編物とした場合、織物や編物の組織は特に限定されない。例えば、編物では、丸編み、横編み、経編み（トリコット）が、織物では、平織、綾織、繻子織が、本発明の風合い効果がよく発揮できることから好ましい繊維構造物の形態である。 When the fiber structure of the present invention is a woven fabric or a knitted fabric, the structure of the woven fabric or the knitted fabric is not particularly limited. For example, circular knitting, weft knitting, and warp knitting (tricot) are preferable for knitting, and plain weaving, twill weaving, and satin weaving are preferable forms of the fiber structure because the texture effect of the present invention can be exhibited well.

The upper limit of the content of the oil-and-fat-containing rayon fiber when mixed is preferably 90% by mass. When the oil and fat-containing rayon fiber is less than 10% by mass, the above-mentioned soft texture tends to be hardly obtained. In addition, when it exceeds 90% by mass, the ratio of the rayon fiber increases, so in addition to the above-mentioned hand effect, the moisture absorption, moisture release, moisture absorption heat generation, and drape properties are high, but the inherent low strength of rayon fiber. It tends to be low dryness (hard to dry), low heat retention, and low stretchability. To supplement such performance, it is preferably combined with other fibers.
上記油脂含有レーヨン繊維に複合する他の繊維は、目的に応じて適宜選択することができ、特に限定されない。例えば、強度を向上させるにはポリエステル繊維を複合することが好ましく、上記油脂含有レーヨン短繊維とポリエステル繊維を混紡する方法、あるいは上記油脂含有レーヨン繊維とポリエステル繊維を長繊維同士で合撚、交編、交織することで複合することが好ましい。また、汗や洗濯の低乾燥性改善にはポリエステル繊維を複合することが好ましい。保温性改善には、ポリアクリル繊維が好ましい。低ストレッチ性改善には、ポリウレタン系弾性繊維が好ましい。発色性アップや屈曲強度改善には、ポリアミド繊維が好ましい。また、コットン（綿）の硬い風合いを改善することやウールの暖かさを加味できるので、かかる繊維を用途、要求に合わせてそれぞれ複合することが好ましい。 Other fibers combined with the oil-and-fat-containing rayon fiber can be appropriately selected according to the purpose, and are not particularly limited. For example, in order to improve the strength, it is preferable to combine polyester fibers, the method of blending the fat-containing rayon short fibers and the polyester fibers, or the oil-containing rayon fibers and the polyester fibers are twisted and knitted together with the long fibers. It is preferable to make a composite by interweaving. Moreover, it is preferable to combine a polyester fiber in order to improve the low drying property of sweat or laundry. For improving heat retention, polyacrylic fibers are preferred. For improving the low stretchability, polyurethane elastic fibers are preferred.

上記表２〜表３のとおり、製造例１〜１０では、乳化剤として、ＨＬＢが１４．５〜１９の第一乳化剤とＨＬＢが６〜１２．５の第二乳化剤を併用することにより、平均粒子径が１μｍ以下と小さく、微分散されているエマルジョン液を調製することができた。一方、第二乳化剤を含んでいない製造例１１のエマルジョン液は、低温安定性が悪かった。また、第一乳化剤を含んでいない製造例１２及び製造例１３の場合は、乳化不良の状態となり、微分散されているエマルジョン液を調製することができなかった。 As shown in Tables 2 to 3, in Production Examples 1 to 10, the average particle is obtained by using a first emulsifier having an HLB of 14.5 to 19 and a second emulsifier having an HLB of 6 to 12.5 as an emulsifier. A finely dispersed emulsion liquid having a diameter as small as 1 μm or less could be prepared. On the other hand, the emulsion liquid of Production Example 11 containing no second emulsifier had poor low-temperature stability. Moreover, in the case of the manufacture example 12 and the manufacture example 13 which do not contain the 1st emulsifier, it became the state of emulsification failure and the emulsion liquid finely dispersed was not able to be prepared.
（実施例１）
＜紡糸用ビスコース液の調製＞
製造例１で調製したエマルジョン液を、油脂含有量がセルロースに対して３質量％になるように、原料ビスコースへ添加し、混合機にて攪拌混合を行い、紡糸用ビスコース液を調製した。温度は２０℃に保った。原料ビスコースとしては、セルロース８．５質量％、水酸化ナトリウム５．７質量％、二硫化炭素２．７質量％を含むビスコース原液を用いた。

The temperature was kept at 20 ° C. As the raw material viscose, a viscose stock solution containing 8.5% by mass of cellulose, 5.7% by mass of sodium hydroxide, and 2.7% by mass of carbon disulfide was used.
＜紡糸条件＞
得られた紡糸用ビスコース液を、２浴緊張紡糸法により、紡糸速度６０ｍ／分、延伸率５０％で紡糸して、繊度が約１．４ｄｔｅｘの椿油含有レーヨン繊維を得た。紡糸浴としては、硫酸１００ｇ／Ｌ、硫酸亜鉛１５ｇ／Ｌ、硫酸ナトリウム３５０ｇ／Ｌ含むミューラー浴（５０℃）を用いた。また、ビスコースを吐出する紡糸口金には、孔径０．０６ｍｍのホールを４０００個有する円形ノズルを用いた。紡糸中、単糸切れ等の不都合は生じず、混合ビスコースの紡糸性は良好であった。
<Spinning conditions>
The obtained viscose liquid for spinning was spun at a spinning speed of 60 m / min and a draw ratio of 50% by a two-bath tension spinning method to obtain a cocoon oil-containing rayon fiber having a fineness of about 1.4 dtex. As the spinning bath, a Mueller bath (50 ° C.) containing 100 g / L of sulfuric acid, 15 g / L of zinc sulfate, and 350 g / L of sodium sulfate was used. In addition, a circular nozzle having 4000 holes having a hole diameter of 0.06 mm was used as a spinneret for discharging viscose. During spinning, there was no inconvenience such as single yarn breakage, and the spinnability of the mixed viscose was good.
＜精練条件＞

（参考例１）
参考例１として、レギュラーレーヨン（ダイワボウレーヨン株式会社製）を用いた。
(Reference Example 1)
As Reference Example 1, regular rayon (manufactured by Daiwabo Rayon Co., Ltd.) was used.
実施例１〜７と参考例１のレーヨン繊維の繊度、乾強度、湿強度、乾伸度及び湿伸度を上記のように測定し、その結果を下記表４に示した。また、実施例１〜７と参考例１のレーヨン繊維のヨウ素価を測定し、その結果を下記表４に示した。また、実施例１、４及び５と参考例１のレーヨン繊維を用いて促進試験を行い、その結果を下記表４に示した。また、実施例５のレーヨン繊維の洗濯耐久性を評価し、その結果を下記表４に示した。 The fineness, dry strength, wet strength, dry elongation and wet elongation of the rayon fibers of Examples 1 to 7 and Reference Example 1 were measured as described above, and the results are shown in Table 4 below. Moreover, the iodine value of the rayon fiber of Examples 1-7 and Reference Example 1 was measured, and the results are shown in Table 4 below. Further, accelerated tests were conducted using the rayon fibers of Examples 1, 4 and 5 and Reference Example 1, and the results are shown in Table 4 below. Moreover, the washing durability of the rayon fiber of Example 5 was evaluated, and the results are shown in Table 4 below.
表４から分かるように、促進試験による実施例の油脂含有レーヨン繊維の繊維強度低下率は、レギュラーレーヨンよりも低かった。この結果から、実施例の油脂含有レーヨン繊維において、油脂は酸化安定性が良好な状態でレーヨン繊維を構成するセルロース内に微分散していることが分かる。また、中性洗剤で５回洗濯した場合、中性洗剤で１０回洗濯した場合、アルカリ洗剤で５回洗濯した場合、アルカリ洗剤で１０回洗濯した場合のいずれの洗濯試験でも、実施例の油脂含有レーヨン繊維のヨウ素価は変化しないことから、洗濯しても油脂は脱落せずセルロース中に存在している、即ち実施例の油脂含有レーヨン繊維は洗濯耐久性に優れることが確認できた。 As can be seen from Table 4, the fiber strength-decreasing rate of the oil-and-fat-containing rayon fiber of the example by the acceleration test was lower than that of the regular rayon. From this result, it can be seen that in the oil-containing rayon fibers of the examples, the oils and fats are finely dispersed in the cellulose constituting the rayon fibers with good oxidation stability. In addition, when the laundry was washed 5 times with a neutral detergent, washed 10 times with a neutral detergent, washed 5 times with an alkaline detergent, or washed 10 times with an alkaline detergent, the fats and oils of the examples were used. Since the iodine value of the contained rayon fibers did not change, it was confirmed that the fats and oils did not fall off even after washing and existed in the cellulose, that is, the fat and oil-containing rayon fibers of the examples were excellent in washing durability.
また、実施例４のレーヨン繊維を脱油処理した後、走査型電子顕微鏡（日立製作所社製「Ｓ−３５００Ｎ」）で観察し、顕微鏡観察結果を図１に示した。図１Ａは、脱油処理後の実施例４のレーヨン繊維における繊維断面の走査型電子顕微鏡写真である（倍率３０００倍）。図１Ｂは、図１Ａの顕微鏡観察結果を画像処理により倍率が９０１０倍になるように部分的拡大した画像である。図１及び２の繊維断面の顕微鏡写真において、繊維断面内の島部分は空隙部であり、この空隙部内部に微分散した油脂が存在していたと考えられる。即ち、脱油処理後の上記レーヨン繊維の繊維断面における空隙部は、微分酸していた油脂が脱油により抜けた後の微小領域部分である。図１Ａ−Ｂからレーヨン繊維内のセルロースと油脂とは非相溶状態で、且つ上記油脂は上記セルロース中に微分散されていることが分かった。そして、実施例４の繊維について、図１Ｂの画像を用いて１００個の空隙部の孔径を測定したところ、平均孔径は０．１４μｍであった。また、実施例５のレーヨン繊維についても、同様に測定したところ、繊維断面における空隙部の平均孔径は０．１５μｍであった。 Moreover, after deoiling the rayon fiber of Example 4, it observed with the scanning electron microscope ("S-3500N" by Hitachi, Ltd.), and the microscope observation result was shown in FIG. FIG. 1A is a scanning electron micrograph of the fiber cross section of the rayon fiber of Example 4 after deoiling treatment (magnification 3000 times). FIG. 1B is an image obtained by partially enlarging the microscope observation result of FIG. 1A by image processing so that the magnification is 9010 times. In the micrographs of the fiber cross section of FIGS. 1 and 2, the island portion in the fiber cross section is a void, and it is considered that finely dispersed oil and fat existed in the void. That is, the void portion in the fiber cross section of the rayon fiber after the deoiling treatment is a minute region portion after the oil and fat that have been differentiated acid are removed by deoiling. From FIG. 1A-B, it was found that the cellulose and the fats and oils in the rayon fiber were in an incompatible state, and the fats and oils were finely dispersed in the cellulose. And about the fiber of Example 4, when the hole diameter of 100 space | gap parts was measured using the image of FIG. 1B, the average hole diameter was 0.14 micrometer. Moreover, when the rayon fiber of Example 5 was also measured in the same manner, the average pore diameter of the voids in the fiber cross section was 0.15 μm.
また、実施例１〜７の油脂含有レーヨン繊維の風合いを官能（触感）試験で評価したところ、ヌメリ感がありソフトな風合いであった。 Moreover, when the texture of the fat and oil-containing rayon fibers of Examples 1 to 7 was evaluated by a sensory (tactile feeling) test, the texture was soft and soft.
本発明の油脂含有レーヨン繊維は、例えば、紡績糸、編物、織物、不織布、トウ、フィラメント、中綿（詰め綿）、紙等の繊維構造物に用いることができる。また、本発明の繊維構造物は、衣料、化粧パフ、吸収体等の衛生材料、ウェットティッシュ、対人・対物ワイパー等のウェットシート、水解性シート、ドライワイパー、フィルター等に用いることができる。 The oil and fat-containing rayon fiber of the present invention can be used for fiber structures such as spun yarn, knitted fabric, woven fabric, non-woven fabric, tow, filament, batting (padded cotton), paper and the like. Further, the fiber structure of the present invention can be used for clothes, cosmetic puffs, hygiene materials such as absorbent bodies, wet tissues, wet sheets such as interpersonal / objective wipers, water-degradable sheets, dry wipers, filters, and the like.
