200938668 九、發明說明 【發明所屬之技術領域】 本發明係關於一種製造纖維素纖維（尤其是溶解性纖 維）的方法，由於此種纖維具有改良開鬆性能，因此很適 合與羽毛混合，尤其是與絨毛混合，此外本發明還包括此 種塡充纖維及以此種塡充纖維與羽毛之混合物塡充寢具及 衣服。 ❹ 【先前技術】 由經過熔化擠壓的合成聚合物（例如聚酯、聚乳酸、 以及其他已知聚合物）形成的細玻璃短纖維被廣泛用來作 爲與絨毛及羽毛混合的塡充纖維。 近年來纖維素纖維--尤其是被BISFA(國際人造纖維 標準局）命名爲Lyocell類的溶解性纖維--早已廣爲人知 ’且多年來一直被大量生產。製造溶解性纖維所使用的溶 ® 劑是—種叔胺氧化物，尤其是N-甲基嗎啉-N-氧化物（ NMM0 )。此外也可以用離子液體作用溶劑。 這些製造方法通常是利用模具擠壓纖維素溶液，然後 成形。接著成形的溶液在一個所謂的乾-濕紡絲程序中通 過沉澱槽的一道氣隙，並在沉澱槽中經由溶液的沉澱形成 固體物。接著將固體物洗淨，並在經過其他必要的處理步 驟後使其乾燥。例如美國專利US 424622 1就有揭示一種 製造溶解性纖維的方法。 也有人將溶解性纖維製作成絨頭織物的形式作爲棉被 -5- 200938668 及枕頭的塡充纖維。例如專利案wo 99/16705也提出以 捲曲的溶解性纖維作爲塡充纖維的作法。但是專利案W0 9 9/16705並未提及纖維纖度、纖維切割長度、或是表面處 理等議題。此外’專利案WO 9 9/16705也沒有提及纖維 的開鬆性能及其相關問題。 專利案WO 2004/070093 A2建議以纖度6.7dtex及切 割長度1 1 mm的溶解性纖維作爲與羽毛及/或絨毛混合的 Ο 成分。溶解性纖維與羽毛及/或絨毛混合的過程是一種濕 法程序。但是專利案WO 20〇4/070093 A2溶解性纖維的開 鬆性及其相關問題並未作任何說明。 專利案WO 2004/023943有關於以纖度〇.7dtex至 8.0dtex及切割長度5mm至100mm的溶解性纖維作爲免 洗棉被（用過即丟的棉被）之塡充材料的詳細說明，此種 免洗棉被完全由溶解性維製成，或是由溶解性纖維與其他 最好是可生物分解的人造纖維的混合物製成。至於以溶解 © 性纖維作爲與羽毛及/或絨毛混合的成分的作法，專利案 WO 2004/023 943僅是附帶一提，並未對相關的加工問題 及如何解決這些問題作任何說明。 專利案 WO 200 5/007945建議以纖度（單位：dtex) 與切割長度（單位：mm )的比値大於或等於〇. 1的溶解 性纖維作爲棉被、軟墊、枕頭、睡墊、以及有軟墊的家具 的纖維性塡充物。此外，專利案WO 2005/0 07945也有提 及將溶解性纖維與其他種類的纖維或羽毛及/或絨毛混合 的作法。 -6- 200938668 例如按照歐洲專利案EP 797 696的方法將以現有技 術製造的纖維與絨毛製成混合物的過程是將紡好的絲直接 在濕的狀態切割’然後作爲絨頭織物送到連續加工區接受 進一步的處理。之後經過清洗步驟去除殘餘的NMMO及 增加光澤’接著將纖維乾燥，然後送到打包機中加壓打包 成捆狀’打包機的壓力最大可達220bar。這種纖維和被製 成線團或不織布的其他類似纖維的製造、加工、以及打包 〇 方式是一樣的。由於倉儲、運輸、以及經濟等原因，因此 不可能降低打包時使用的壓力。 但是絨毛及羽毛的加工並不像製造紡織物一樣另外有 開鬆機具可供使用。由於常被用來製作混合纖維的合成纖 維（例如聚酯）本身很容易開鬆，因此這種纖維的加工不 需要使用侵入性的開鬆機具。大部分的絨毛及羽毛是在乾 燥狀態下被加工，因此是以通風機及鼓風機作爲開鬆、混 合、以及輸送絨毛及羽毛的機具。因此如果以前面提及之 © 方法製造的溶解性纖維作爲與絨毛及羽毛混合的混合成分 ，就會因爲纖維在被打包成捆時經過高壓壓製而變得開鬆 性不足。因此可能形成結成塊狀的固化纖維被送入後面的 加工機器中，導致加工機器損壞。也就是說絨毛及羽毛無 法與這種纖維成均勻的混合。專利案WO 2005/007945並 未提及如何解決市面上常見之壓製成捆的纖維在使用現有 之絨毛加工機器與絨毛混合時的開鬆性不足的問題。 目標： 200938668 本發明的目標是提出一種能夠改善現有技術之缺點纖 維，此種纖維不需使用紡織工業常用之開鬆機具即可開鬆 ，並能夠與絨毛及羽毛均勻混合。 本發明的另外一項目標是提出一種製造纖維的方法， 此種纖維不需使用紡織工業常用之開鬆機具即可開鬆，並 能夠與絨毛及羽毛均勻混合。 © 解決方法： 採用單一纖維纖度0.7dtex至6.0dtex (最好是0.8dtex 至3.Odtex)的纖維素塡充纖維即可達成上述第一項目標 。此種塡充纖維具有一增光澤塗層，且頂锻室內形成之捲 曲的彎曲數至少是18彎曲/10cm。此外，這種塡充纖維經 過高壓打包成市面常見的捆狀纖維後具有很好的開鬆性能 ，且只需簡單的機具即可處理，此點可以利用所謂的吹風 箱試驗（b 1 〇 w b ο X t e s t )加以證明。 © 單一纖維纖度明顯小於〇.7dtex的纖維對作爲塡充用 的塡充纖維而言過於細緻，例如這麼細緻的纖維可能會缺 乏足夠的膨脹性。單一纖維纖度明顯大於6. Odtex的纖維 對作爲塡充用的塡充纖維而言則是太粗和太硬’因此無法 符合消費者對於絨毛及羽毛類產品的要求。 頂锻捲曲係按照專利案WO 95/24520提出的方法進 行。一個令人訝異的發現是，此種纖維的開鬆性能優於以 前面所述之絨頭織物加工方式製造之溶解性纖維。尤其令 人感到訝異的是，在頂鍛室內捲曲的纖維能夠開鬆的程度 -8 - 200938668 遠優於經絨頭織物加工捲曲的纖維。 此處必須特別強調的是，在頂锻室內捲曲的纖維與經 絨頭織物加工捲曲的纖維有明顯的不同。例如按照歐洲專 利案EP 797 696的方式捲曲的絨頭織物纖維會帶有永久 性的擠壓處，利用偏光影微鏡可以將這些擠壓處看得很清 楚。雖然這種絨頭織物纖維在許多不同的紡織物及其他應 用上具有很多優點，但是對本發明而言卻因爲其開鬆性能 〇 不好而被視爲一大缺點。 【發明內容】 本發明之塡充纖維的彎曲數是18至50彎曲/10 cm， 或最好是18至40彎曲/10 cm。彎曲數少於前述範圍的缺 點是塡充纖維的膨脹性會不足，彎曲數超出前述範圍的缺 點是塡充纖維的開鬆性能會變差，因爲在這種情況下，單 一纖維之間可能會出現鉤結現象。 ® 此外，增光澤塗層佔增光澤纖維總重量的〇. 3 %至 3 . 〇% (重量百分比）。增光澤塗層佔的比例過低會使纖維 的光滑性變差，導致開鬆性能變差；增光澤塗層佔的比例 過高的缺點包括成本較高（因爲化學藥品用量增加）、使 纖維的觸感變得太濕或太滑、以及導致開鬆性能及加工性 能變差。 最好是以一種胺基官能基化的增光澤劑進行塡充纖維 的增光澤處理。增光澤劑中的胺基官能基對於調整本發明 之塡充纖維的光滑性有很大的貢獻，而光滑性對於纖維的 -9- 200938668 開鬆性能及必要的膨脹性是很重要的。官能基化的方式對 光滑性的影響大於增光澤劑之基本成分對光滑性的影響。 目前已知的所有相關化合物均可作爲增光澤劑的基本 成分，例如矽油、或是脂肪酸爲主要成分的增光澤劑。但 是對本發明而言，最好是以矽油作爲增光澤劑的基本成分 ，原因是矽油的持久性最佳。此處所謂的持久性是指長時 間停留在纖維上的能力，例如即使是經過多次清洗仍能夠 © 停留在纖維上。 穩定纖維長度（也稱爲切割長度）對於本發明之塡充 纖維的開鬆性能及加工性有大體的影響。一個令人訝異的 發現是，本發明的塡充纖維在穩定纖維長度爲6mm至 2 0mm時具有最佳的特性。穩定纖維長度太長的缺點是鉤 結處會變多，因而導致開鬆性能變差。在頂锻室內捲曲的 纖維束是在伸展開來的狀態下被切割，也就是說是放在市 面上常見的切割機內被拉直，然後被切割成事先設定的長 ❹度。 一件令人訝異的發現是利用所謂的吹風箱試驗可以檢 驗一種纖維是否適於作爲具有良好之開鬆性能的塡充纖維 。這對於確保產品品質是非常重要的。不良的開鬆性能會 招致客戶的投訴，因爲如前面所述，以現有的機具完全無 法使這種打包成捆狀的纖維開鬆（或是無法使其足夠開鬆 )。開鬆程度不足的纖維甚至可能造成塡充纖維加工廠的 加工機器受損，因而使纖維生產商面臨損害賠償的要求。 吹風箱的高度比例愈大，纖維就愈容易被塡充纖維加 -10- 200938668 工廠擁有的一般機具開鬆。因此本發明的塡充纖維的吹風 箱的高度比例應在4至1 5之間，或最好是在6至14之間 〇 採用一種製造單一纖維纖度0.7dtex至6.0dtex (最好 是0.8dtex至3.0dtex )之纖維素塡充纖維的方法即可達成 本發明的另外一項目標。此方法具有以下的步驟： a.製作一種含纖維素的紡絲溶液； O b ·將紡絲溶液紡成纖維束； c.對纖維束進行清洗、乾燥、捲曲、以及增光澤等 加工程序，以便在頂鍛室內將纖維束捲曲成至少具有18 彎曲/10cm個彎曲數，然後再切割，並使切割出的塡充纖 維的吹風箱的高度比例在4至1 5之間，或最好是在6至 1 4之間。 本發明的方法最好是使用一種胺基官能基化的增光澤 劑。 © 本發明的方法最好以矽油作爲增光澤劑。 增光澤塗層也是決定塡充纖維之開鬆性能及加工特性 的一個重要條件。增光澤塗層應佔增光澤纖維總重量的 0 · 3 %至3.0 % (重量百分比）。 最好是在乾-濕紡絲程序（例如一種已知的溶解性纖 維程序）中以含水胺氧化物或離子液體作爲纖維素的溶劑 將纖維紡絲。 要達成本發明之目標亦可採用一種單一纖維纖度 0.7dtex 至 6.0dtex (或最好是 〇.8dtex 至 3 〇dtex)的纖維 -11 - 200938668 素塡充纖維作爲寢具及衣服的塡充材料，且此種纖維素塡 充纖維具有一增光澤塗層’且在頂鍛室內形成之捲曲的彎 曲數至少是18彎曲/l〇cm。 此種纖維素塡充纖維的吹風箱高度比例在4至1 5之 間’或最好是在6至14之間。 此種纖維素塡充纖維可以與絨毛及/或羽毛混合，也 可以與聚酯、聚乳酸、及/或聚丙烯混合。此種纖維素塡 © 充纖維亦可與天然纖維（例如木棉纖維或白楊樹纖維）混 合。 【實施方式】 彎曲數的測定： 按照專利W 0 9 5 / 2 4 5 2 0提出的方法測定彎曲數。 吹風箱試驗（blow box test): 可以在實驗室中利用以下描述的方法--也就是所謂的 吹風箱試驗--檢驗與絨毛及羽毛混合之填充纖維的開鬆性 能： 吹風箱是一個矩形的金屬容器，其底面是開放的，頂 面則覆蓋一片可透氣的金屬篩網。吹風箱的尺寸爲20x15 x20cm (長X寬X局），也就是說谷積爲6公升。位於頂面 之可透氣金屬篩網的篩眼大小約爲〇.8mm。從一個噴嘴噴 出的固定不變的空氣流通過金屬篩網將纖維捲揚起來。多 餘的空氣也是通過金屬篩網向外流出。 -12- 200938668 按照以下方式測定開鬆性能，爲了獲得可靠的結果， 每次計算均應取兩次試驗的平均値： 測定原始高度： 用手從經壓縮打包成捆的纖維中取出5g未經機器開 鬆的纖維，首先按照BISFA規範（BISFA手冊“嫘縈、 纖維束、溶解性纖維、醋酸纖維、纖維及絲束的試驗方法 ❹ ” ，2004年版）在標準大氣（20°C，相對濕度65% )的環 境中進行預處理，然後小心的將經過預處理的纖維放到一 個容量3000ml、直徑14.5cm的燒杯中，並測量裝塡高度 〇 接著將這些纖維放到吹風箱內。經由一個噴嘴在金屬 筛網上方1cm的位置向吹風箱內吹入空氣（吹入斷面 4mm) ’以便使纖維捲揚起來並開鬆，如第2圖所示，吹 入空氣時應將噴嘴之噴頭部分置於距吹風箱右邊邊緣6cm © 處並傾斜4 5度對準吹風箱中心。 計算吹風箱高度： 如第3圖所示’接著小心的將在吹風箱內開鬆的纖維 重新放回容量3000ml、直徑14.5cm的燒杯中，並重新測 量裝塡高度。 計算吹風箱高度比例： 所謂吹風箱高度比例是指將吹風箱高度除以原始高度 -13- 200938668 所得的商。 另外再以目視方式按照以下的評分標準對纖維的開鬆 性能進行評分： 1分：無任何開鬆性能 5分：一半的纖維有開鬆 1 〇分：所有的纖維都有開鬆 第4圖的例子顯示分數爲9分的纖維開鬆狀況。 ❿ 實施例： 實施例1 (供比較之用）： 按照已知的方法經由擠壓纖維素在胺氧化物中的含水 溶液形成單一纖維纖度1.7dtex的溶解性纖維，並在一個 乾-濕紡絲程序中凝結，然後利用現有技術在絨頭織物加 工程序中對纖維進行切割、清洗、乾燥、以及以矽油增光 澤等加工步驟，最後使纖維具有一個佔纖維總重量0.8% ❹ 至1.2% (重量百分比）的增光澤塗層。增光澤塗層佔纖 維總重量的比例不是一個固定的數値，因爲即使是很小心 的將增光澤劑塗上去，在纖維中的塗層仍會在一定範圍內 變動。利用市面常見的Autefa公司生產的打包機按照生 產規模的需求將所獲得的纖維壓縮打包成捆。然後按照前 面所述的方法取樣。 實施例2及實施例3(使用本發明的方法）： 按照已知的方法經由擠壓纖維素在胺氧化物中的含水 -14- 200938668 溶液形成單一纖維纖度1.7dtex的溶解性纖維，並在一個 乾-濕紡絲程序中凝結，然後在纖維束加工程序中對纖維 進行清洗、乾燥、在頂鍛室內捲曲、以及以胺基官能基化 的矽油（型號：Wacker finish CT96E)增光澤等加工步驟 ，最後使纖維具有一個佔纖維總重量0.7%至0.9% (重量 百分比）的增光澤塗層。接著再將纖維束切割。利用市面 常見的Autefa公司生產的打包機按照生產規模的需求將 〇 所獲得的纖維壓縮打包成捆。然後按照前面所述的方法取 樣。 利用本發明的方法製造之纖維的開鬆性能遠優於以現 有技術製造之纖維。 實施例 1 2 3 製造 絨頭織物 卷曲的纖維束 卷曲的纖維束 _切割長度[mm] 11 12 20 彎曲數 -- 20-25 20-25 吹風箱試驗分數 2 6 6 原始高度[cm] 2 2 2 吹風箱高度『cm] 6 23 24 風箱高度比例 3 11.5 12 -15-200938668 IX. INSTRUCTIONS OF THE INVENTION [Technical Field] The present invention relates to a method for producing cellulose fibers (especially soluble fibers) which are suitable for mixing with feathers, especially since the fibers have improved opening properties. In combination with the fluff, the present invention also encompasses such ampoules and the use of such a mixture of enamel fibers and feathers to refill the bedding and clothing. ❹ [Prior Art] Fine glass short fibers formed from melt-extruded synthetic polymers such as polyester, polylactic acid, and other known polymers are widely used as the entangled fibers mixed with fluff and feathers. In recent years, cellulose fibers, especially those classified as Lyocells by BISFA (International Manmade Fiber Standards Bureau), have long been widely known and have been mass-produced for many years. The solvent used to make the soluble fiber is a tertiary amine oxide, especially N-methylmorpholine-N-oxide (NMM0). It is also possible to use a solvent for the ionic liquid. These manufacturing methods usually use a mold to press a cellulose solution and then form. The formed solution is then passed through an air gap in the sedimentation tank in a so-called dry-wet spinning process and a solid is formed in the sedimentation tank by precipitation of the solution. The solid is then washed and allowed to dry after other necessary processing steps. A method of making a soluble fiber is disclosed, for example, in U.S. Patent No. 4,246,622. It has also been made into a pile fabric in the form of a pile fabric as a quilt -5 - 200938668 and a quilt of a pillow. For example, the patent WO 99/16705 also proposes the use of crimped, soluble fibers as the entangled fibers. However, the patent case W0 9 9/16705 does not mention issues such as fiber denier, fiber cut length, or surface treatment. Furthermore, the patent WO 9 9/16705 does not mention the opening properties of the fibers and their associated problems. The patent WO 2004/070093 A2 proposes a soluble fiber having a fineness of 6.7 dtex and a cutting length of 1 1 mm as a bismuth component mixed with feathers and/or fluff. The process of mixing dissolved fibers with feathers and/or fluff is a wet procedure. However, the openness of the soluble fiber of the patent WO 2〇4/070093 A2 and related problems are not explained. Patent application WO 2004/023943 relates to a detailed description of a fused material of a disposable quilt (used or lost quilt) with a denier of 7.7dtex to 8.0dtex and a cutting length of 5mm to 100mm. The disposable quilts are made entirely of soluble sizing or by a mixture of soluble fibers and other preferably biodegradable rayon. As for the method of dissolving the conjugated fiber as a component mixed with feathers and/or fluff, the patent WO 2004/023 943 is only attached, and does not explain the related processing problems and how to solve the problems. Patent WO 200 5/007945 proposes that the ratio of the fineness (unit: dtex) to the length of the cut (unit: mm) is greater than or equal to 溶解. 1 of the soluble fiber as a quilt, cushion, pillow, sleeping mat, and Fibrous swells of upholstered furniture. In addition, the patent WO 2005/0 07945 also mentions the practice of mixing dissolved fibers with other types of fibers or feathers and/or fluff. -6- 200938668 The process of mixing a fiber made from the prior art with fluff, for example, according to the method of European Patent No. EP 797 696, is to cut the spun yarn directly in a wet state and then send it to the continuous processing as a pile fabric. The district accepts further processing. The cleaning step is then followed by removal of residual NMMO and increased gloss. The fibers are then dried and then sent to a baler and pressurized to pack into a bale. The pressure of the baler can be up to 220 bar. This type of fiber is manufactured in the same manner as other similar fibers that are made into coils or non-woven fabrics. Due to warehousing, transportation, and economic reasons, it is impossible to reduce the pressure used in packaging. However, the processing of fluff and feathers is not as open as the manufacture of textiles. Since the synthetic fibers (e.g., polyester) which are often used to make mixed fibers are easily opened by themselves, the processing of such fibers does not require the use of invasive opening implements. Most of the fluff and feathers are processed in a dry state, so fans and blowers are used as tools for opening, mixing, and conveying fluff and feathers. Therefore, if the dissolving fiber produced by the above-mentioned © method is used as a mixed component mixed with fluff and feather, the fiber becomes insufficiently opened because it is subjected to high pressure pressing when it is packed into a bundle. Therefore, it is possible to form a solidified fiber which is formed into a block and is fed into a subsequent processing machine, resulting in damage to the processing machine. This means that the fluff and feathers cannot be evenly mixed with the fibers. Patent WO 2005/007945 does not mention how to solve the problem of insufficient openness of fibers which are commonly used in the production of bundled fibers when mixed with fluff using existing fluff processing machines. OBJECTIVE: 200938668 The object of the present invention is to propose a fiber which is capable of improving the disadvantages of the prior art, which can be opened without the use of an opening machine commonly used in the textile industry, and can be uniformly mixed with fluff and feathers. Another object of the present invention is to provide a method of making a fiber which can be opened without the use of an opening machine commonly used in the textile industry, and can be uniformly mixed with fluff and feathers. © Solution: The first objective is to achieve a cellulose fiber with a single fiber denier of 0.7 dtex to 6.0 dtex (preferably 0.8 dtex to 3.Odtex). The entangled fibers have a gloss enhancing coating and the number of bends formed in the upset forging is at least 18 bends/10 cm. In addition, the reinforced fiber has a good opening performance after being packed into a commercially available bundle fiber by high pressure, and can be handled by a simple machine, which can be tested by a so-called blow box (b 1 〇wb) ο X test ) to prove. © Fibers with a single fiber fineness significantly less than 〇.7dtex are too fine for the entangled fibers used for filling. For example, such fine fibers may lack sufficient expansion. The single fiber fineness is significantly greater than 6. Odtex's fiber is too thick and too hard for the entangled fiber as a filling. Therefore, it cannot meet the consumer's requirements for fluff and feather products. The upset crimping is carried out in accordance with the method proposed in the patent WO 95/24520. One surprising finding is that the opening properties of such fibers are superior to the soluble fibers produced by the method of processing the pile fabric described above. Particularly surprising is the fact that the fibers that are crimped in the upset forging can be opened to a degree -8 - 200938668 which is much better than the crimped fibers processed by the pile fabric. It must be particularly emphasized here that the fibers crimped in the upset forging are significantly different from the fibers that are crimped by the pile fabric. For example, the pile fabric fibers crimped in the manner of the European patent EP 797 696 will have a permanent squeezing point, which can be seen clearly by means of a polarizing micromirror. While such pile fabric fibers have many advantages over many different textiles and other applications, they are considered a major disadvantage for the present invention because of their poor opening properties. SUMMARY OF THE INVENTION The number of bends of the entangled fibers of the present invention is 18 to 50 bends/10 cm, or preferably 18 to 40 bends/10 cm. A disadvantage of the number of bends being less than the aforementioned range is that the expandability of the entangled fibers is insufficient, and the disadvantage that the number of bends exceeds the aforementioned range is that the opening properties of the entangled fibers are deteriorated, because in this case, a single fiber may be between Hooking occurs. ® In addition, the gloss-increasing coating accounts for 〇. 3 % to 3 % 重量 % (% by weight) based on the total weight of the gloss-increasing fibers. If the proportion of the gloss-increasing coating is too low, the smoothness of the fiber will be deteriorated, resulting in poor opening properties; the disadvantage of the excessive proportion of the gloss-increasing coating includes higher cost (because of the increased amount of chemicals), the fiber The feel of the touch becomes too wet or too slippery, and the opening performance and the processing property are deteriorated. Preferably, the glossing of the entangled fibers is carried out with an amine functionalized glossing agent. The amine functional groups in the brightening agent contribute greatly to the smoothness of the entangled fibers of the present invention, and the smoothness is important for the opening properties of the fibers -9-200938668 and the necessary expansion properties. The effect of the functionalization on the smoothness is greater than the effect of the basic components of the glossing agent on the smoothness. All of the related compounds currently known can be used as a basic component of a brightening agent, such as emu oil or a brightening agent containing a fatty acid as a main component. However, for the present invention, it is preferable to use eucalyptus oil as an essential component of the glossing agent because the eucalyptus oil has the best durability. The term "permanence" as used herein refers to the ability to stay on the fiber for a long period of time, for example, even after repeated cleaning, it can remain on the fiber. The stabilizing fiber length (also referred to as the cut length) has a general influence on the opening properties and workability of the entangled fibers of the present invention. One surprising finding is that the entangled fibers of the present invention have the best characteristics when the length of the stabilized fibers is from 6 mm to 20 mm. The disadvantage of the length of the stabilizing fiber being too long is that the number of hooks is increased, resulting in poor opening properties. The bundle of fibers crimped in the upset forging is cut in a stretched state, that is, it is straightened in a common cutting machine on the market, and then cut into a predetermined length. An amazing finding is the use of so-called blow box tests to test whether a fiber is suitable as a reinforced fiber with good opening properties. This is very important to ensure product quality. Poor opening performance can lead to customer complaints because, as mentioned earlier, it is completely impossible to open the bundled fibers (or not to make them loose enough) with existing implements. Fibers that are not open enough may even cause damage to the processing machinery of the fiber-filled processing plant, thus placing fiber manufacturers with damages. The higher the proportion of the height of the blow box, the easier it is for the fiber to be filled with fiber -10- 200938668 The general machine owned by the factory is opened. Therefore, the height ratio of the blow-on fiber of the present invention should be between 4 and 15 or, preferably between 6 and 14, using a single fiber denier of 0.7 dtex to 6.0 dtex (preferably 0.8 dtex). Another method of the present invention can be achieved by a method of cellulose entanglement of up to 3.0 dtex. The method has the following steps: a. preparing a spinning solution containing cellulose; O b · spinning the spinning solution into a fiber bundle; c. processing the fiber bundle for washing, drying, curling, and glossing, In order to curl the fiber bundle into at least 18 bends / 10 cm bends in the upset forging, and then cut, and the ratio of the height of the cut blown fiber to the blow box is between 4 and 15 or preferably Between 6 and 14 4. Preferably, the process of the invention utilizes an amine functionalized gloss enhancer. © The method of the present invention preferably uses emu oil as a brightening agent. The gloss-increasing coating is also an important condition for determining the opening properties and processing characteristics of the reinforced fibers. The gloss-increasing coating should comprise from 0. 3 to 3.0% by weight based on the total weight of the gloss-increasing fibers. Preferably, the fibers are spun in a dry-wet spinning process (e.g., a known dissolved fiber procedure) using an aqueous amine oxide or ionic liquid as the solvent for the cellulose. To achieve the object of the present invention, a fiber having a single fiber denier of 0.7 dtex to 6.0 dtex (or preferably 〇.8 dtex to 3 〇dtex) can be used as a reinforcing material for bedding and clothes. And the cellulose reinforced fiber has a gloss enhancing coating and the number of crimps formed in the upset chamber is at least 18 bends/l〇cm. The ratio of the height of the blow box of such cellulose entangled fibers is between 4 and 15 or preferably between 6 and 14. The cellulose entangled fibers may be mixed with fluff and/or feathers, or may be mixed with polyester, polylactic acid, and/or polypropylene. This cellulose 塡 © fiber can also be mixed with natural fibers such as kapok fiber or poplar fiber. [Embodiment] Measurement of the number of bends: The number of bends was measured in accordance with the method proposed in the patent W 0 9 5 / 2 4 5 2 0. Blow box test: The opening method of filling fibers mixed with fluff and feathers can be tested in the laboratory using the method described below - the so-called blow box test: The blow box is a rectangular The metal container has a bottom surface that is open and a top surface that is covered with a gas permeable metal screen. The size of the blow box is 20x15 x 20cm (length X width x board), which means that the grain volume is 6 liters. The mesh size of the gas permeable metal mesh on the top surface is about 〇8 mm. The constant air flow ejected from a nozzle winds up the fiber through a metal screen. The excess air also flows out through the metal screen. -12- 200938668 The opening properties were determined in the following manner. For reliable results, the average enthalpy of the two tests should be taken for each calculation: Measure the original height: Remove 5 g from the compressed bundled fibers by hand. The open fiber of the machine is first in accordance with the BISFA specification (BISFA manual "Test methods for enamel, fiber bundles, soluble fibers, acetate, fiber and tow", 2004 edition) in standard atmosphere (20 ° C, relative humidity) Pretreatment was carried out in an environment of 65%), and then the pretreated fibers were carefully placed in a beaker having a capacity of 3000 ml and a diameter of 14.5 cm, and the height of the mounting was measured, and then the fibers were placed in a blow box. Air is blown into the blow box at a position of 1 cm on the metal screen through a nozzle (injection section 4 mm) 'to make the fiber hoist and open, as shown in Fig. 2, the nozzle should be blown when blowing air The nozzle portion is placed 6 cm away from the right edge of the blow box and tilted 4 5 degrees to the center of the blow box. Calculate the height of the blow box: As shown in Figure 3, then carefully put the loose fibers in the blow box back into the beaker with a capacity of 3000 ml and a diameter of 14.5 cm and re-measure the height of the mounting. Calculate the height ratio of the blow box: The so-called blow box height ratio refers to the quotient obtained by dividing the blow box height by the original height -13- 200938668. In addition, the fiber opening performance was scored visually according to the following scoring criteria: 1 point: no opening performance 5 points: half of the fiber had opening 1 〇 points: all fibers had opening 4 The example shows a fiber opening condition with a score of 9 points.实施 Example: Example 1 (for comparison): a single fiber fineness of 1.7 dtex of soluble fiber was formed by extruding an aqueous solution of cellulose in an amine oxide according to a known method, and in a dry-wet spinning Coagulation in the silk process, and then using the prior art to cut, clean, dry, and lubricate the fibers in a pile fabric processing program, and finally have a fiber having a total fiber weight of 0.8% 1.2 to 1.2% ( Weight percent) glossing coating. The proportion of the gloss-increasing coating to the total fiber weight is not a fixed number, because even if the glossing agent is applied with great care, the coating in the fiber will vary within a certain range. The obtained fibers are packaged into bundles in accordance with the production scale by using a baling machine manufactured by Autefa, which is common in the market. Then sample as described previously. Example 2 and Example 3 (using the method of the present invention): forming a single fiber denier 1.7 dtex of soluble fiber by extruding a solution of cellulose in an amine oxide in aqueous-14-200938668 according to a known method, and Coagulation in a dry-wet spinning process, followed by fiber cleaning, drying, crimping in the upset chamber, and amine-functionalized eucalyptus oil (model: Wacker finish CT96E) In the end, the fibers are finally provided with a gloss enhancing coating in an amount of from 0.7% to 0.9% by weight based on the total weight of the fibers. The fiber bundle is then cut. The bales obtained from Autefa, which is commonly used in the market, are compressed into bundles according to the production scale. Then take the sample as described above. The fibers produced by the process of the present invention have much better opening properties than fibers made by the prior art.
