造纖維應運而生。人造纖維可分為再生纖維和合成纖維二 大類。其中’再生纖維（如嫘縈、醋酸纖維等）是將天然纖維 素重新以化學處理而形成。而合成纖維（如尼龍、聚酯、亞 克力纖維等）則是以石油資源為原料，經化學聚合再抽絲而 成的纖維。 但疋，石油資源不僅是屬於一種不可再生的資源，而 且在其聚合為合成纖維的過程中更會產生污染的問題。此 外’以合成纖維編織而成的織布於使用後也無法降解。然 ==於近年㈣料求㈣㈣漸高m，因此纖維製造 用天然的再生原料’例如以纖維素作為纺織原 枓，以改善環境污染之問題。 2素（⑽1。啦—種天然㈣保素材。其不僅且有 可：：舒::能: 污染的織布。目十，· 纖維素製造出天然實用且低 季服都等衣物上。】”維素纖維f使用於内衣、内襯或夏 然而，纖維素的纖維織物之功用僅偈限於具良好的舒 1293654 適性，並無法進一步提供其他的機能。因此，最有效的方 法就是添加具機能性的粒子至纖維製程中，以增加纖維製 抑之機旎性。但在先前技術中僅僅是將具有機能性的粒子 添加至纖維素中，然後藉由攪拌或是捏合的方式，將機能 陡粒子分散於溶液之中。然而，這種傳統的攪拌或捏合方 式不僅無法讓機能性粒子均勻地分散於溶液中而達到良好 的分散效果，且很料於後續的製程中再發生凝聚的現 象。即使疋利用分散劑或是乳化劑，也會因為粒子過大或 因儲存時間過長而導致二次凝聚，甚至是發生結塊的現 象。如此一來，於加工過程中會發生不均勻的現象，甚至 造成無法加工的情形。 因此，如何製造具機能性且分散性良好之機能懸浮液 且應用於再生纖維素製程中，以製造環保且實㈣纖維織 布，實為紡織工業與消費者所企盼。 【發明内容】 口此本發明的目的就是在提供—種纖維素之多機能再 生纖維之製造方法，心改善製造過"所產生環境污染 之問題。 本發明的另一 纖維之製造方法， 的再生纖維織物。 目的是在提供一種纖維素之多機能再生 用以得到一天然且可自然分解之纖維素 本發明的又-目的是在提供一種纖維素之多機能再生 纖維之製造方法，用以提高纖維素的再生纖維之抗菌性、 除臭性以及运紅外線升溫效果。 1293654 本發明的再一目的是在提供一種纖維素之多機能再生 纖維之快速製造方法。將預先製備好的多機能炭粉的懸浮 液與纖維素溶液均勻混合，以形成一紡絲液。再利用濕式 纺絲法而紡絲成多機能再生纖維，以提高多機能再生纖維 之產率。 根據本發明之上述目的，提出一種纖維素之多機能纖 維之製造方法。依照本發明一較佳實施例，係先製備具高 分散性之多機能炭粉之懸浮液。再將纖維素添加於溶劑 中’均勻攪拌至纖維素完全溶解，以形成纖維素溶液。 接著’將纖維素溶液與多機能炭粉的懸浮液混合，並 均句授拌以形成纖維紡絲液。最後利用濕式紡絲法，使得 纖維紡絲液形成纖維素的多機能再生纖維。其中上述之纖 維素的多機能再生纖維係為黏膠纖維、Lyocell纖維、醋酸 纖維或上述纖維之衍生纖維。 由上述本發明之較佳實施例可知，應用本發明之方法 所製備而成的纖維素之多機能再生纖維及其織物，皆具有 較佳之抗菌效果、高除臭率以及遠紅外線之升溫效果。此 方法係使用纖維素作為纖維原料，不僅能改善先前技術所 導致的環境污染問題，更能編織成天然且實用的纖維素的 纖維織布。 且本發明之方法不僅能得到自然可分解的纖維素的纖 維織物，更能藉由添加機能性炭粉於纖維中，以形成纖維 素之多機能再生纖維，進而提高纖維素的纖維織物之機能 性。除此之外，本發明之方法係先製備機能性且分散性良 好之機能懸浮液，並將此懸浮液應用於再生纖維素製程 7 Ϊ293654 中，以製造環保且實用性高的纖維織布。 【實施方式】 本發明能有效提供一種天然且實用之纖維織布，同時 於製造過程中不產生污染問題。並且，於此天然織布中加 入功能性粒子，以提高天然纖維織布的機能性。 首先製備多機能炭粉的懸浮液，用以提高纖維素織布 的機能性。在本發明之一較佳實施例中，將分散劑與潤濕 劑溶於溶劑中，接著進行攪拌直至混合均勻。再將多機能 炭粉加入混合液中並進行高速攪拌。隨後進行研磨分散製 程以形成多機能炭粉的懸浮液。 其中’上述之多機能炭粉較佳為竹炭粉、木炭粉、備 長炭粉、活性炭粉、椰子殼炭粉、蚵殼炭粉或海藻炭粉， 且其係以較佳溫度約為3〇〇。〇到15〇〇〇c燒製原料後粉碎而 成而懸浮液中的多機能炭粉之重量百分比較佳範圍為 5 50 /。。研磨後之多機能炭粉的平均粒徑較佳為小於ο』 μπι且90 A之粉末粒徑較佳為小於1 。此外，上述用來 懸>于多機能碳粉之溶劑較佳為水、苯類、醇類、醛類或酚 類。 上述之分散劑之成分較佳為聚萘磺酸、曱醛及甲基酚 納鹽類共聚物、馬來酐二異丁烯類共聚物、聚萘甲醛磺酸 納鹽類、續酸缓酸醋類、續酸鹽類、脂肪酸類、聚丙稀酸 酯類、聚丙烯酸鹽類、聚醚類、聚羧酸類、聚氨基甲酸酯 類、聚石夕氧燒類共聚物與績酸鹽類共聚物之任意組合。由 上述較佳成份所組成之分散劑較佳為高分子量分散劑、低 8 1293654 分子量分散劑、陰離子型分散劑、陽離子型分散劑或非離 子型分散劑。 在本發明中之一些較佳實施例，分散劑係採用由余泰 貿易公司所提供，型號分別為Galoryl PT201、Galoryl PT245L、Galoryl DT50、Galoryl TD2卜 Galoryl MT 830ML、 Galoryl DT23、Galoryl MT 830ML、Galoryl TD164L 之分散 劑。或是由TEGO公司所提供，型號分別為Dispers 610、 Dispers 630、Dispers 650、Dispers 651、Dispers 652、Dispers 700、Dispers 710、Dispers 740W、Dispers 745、Dispers 750、 Dispers 752W、Dispers 760W 之分散劑。 濕潤劑之成分較佳為之成分較佳為聚萘磺酸、甲醛及 曱基酚納鹽類共聚物、馬來酐二異丁烯類共聚物、聚萘甲 醛磺酸鈉鹽類、磺酸羧酸酯類、磺酸鹽類、脂肪酸類、聚 丙烯酸酯類、聚丙烯酸鹽類、聚醚類、聚羧酸類、聚氨基 甲酸酯類、聚矽氧烷類共聚物與磺酸鹽類共聚物之任意組 合。在本發明之一些較佳實施例中，上述之濕潤劑係採由 TEGO公司所提供，型號分別為WET500、WET501、 WET502、TEGO WET270、TEGO WET245 之濕潤劑。或是， 由余泰貿易公司所提供，型號分別為Sulfoxyl 80、Galoryl TR16、BP、OD40 之濕潤劑。 然後，開始製備纖維素溶液。添加適量之纖維素於第 一溶劑中並攪拌均勻，使纖維素能溶解於溶劑中，以形成 纖維素溶液。其中，上述之纖維素係選自於紙、紙製品、 木材、木材纖維、木材原料、洋麻 '草莖、米糠、甘蔗渣、 棉、黃麻或上述纖維素原料之任意組合，且上述之纖維原 9 1293654 料複合物的抗彎強度較佳為至少3000 psi。而上述用來溶解 纖維素之溶劑較佳為氫氧化納溶液、N-甲基嗎啉N-氧化物 (N-methylmorpholine-N-oxide ;

Man-made fibers can be classified into two major categories: regenerated fibers and synthetic fibers. Among them, 'regenerated fibers (e.g., hydrazine, acetate, etc.) are formed by re-chemically treating natural cellulose. Synthetic fibers (such as nylon, polyester, acrylic fibers, etc.) are made from petroleum resources and chemically polymerized and then drawn. However, oil resources are not only a non-renewable resource, but also a problem of pollution in the process of polymerizing into synthetic fibers. In addition, the woven fabric woven with synthetic fibers cannot be degraded after use. However, in recent years (4), it is expected that (4) (4) gradually increase m, so the fiber is manufactured using natural recycled raw materials, such as cellulose as a textile raw material, to improve environmental pollution. 2 vegetarian ((10)1. La-species natural (four) material. Not only does it have:: Shu:: Can: Contaminated weaving. Mesh 10, · Cellulose produces natural and practical clothes in low seasons.] "Vecin fiber f is used in underwear, lining or summer. However, the function of cellulose fiber fabric is limited to good fitness 1293654, and no further function can be provided. Therefore, the most effective method is to add function. Sex particles into the fiber process to increase the flexibility of the fiber system. However, in the prior art, only the functional particles are added to the cellulose, and then the function is steep by stirring or kneading. The particles are dispersed in the solution. However, this conventional stirring or kneading method not only does not allow the functional particles to be uniformly dispersed in the solution to achieve a good dispersion effect, and is expected to re-agglomerate in subsequent processes. Even if you use a dispersant or an emulsifier, it will cause secondary aggregation or even agglomeration due to excessive particles or long storage time. Unevenness may occur during the process, and even the process may not be processed. Therefore, how to make a functional and dispersible functional suspension and apply it to the regenerated cellulose process to manufacture environmentally friendly (4) fiber woven fabrics The present invention is intended to provide a method for producing a multi-functional regenerated fiber of cellulose, and to improve the environmental pollution caused by the manufacture of the cellulose.

Subsequently, preferably 15 g of cellulose is added to the NMMO solution and heated with stirring to allow the cellulose to be completely dissolved in the NMMO aqueous solution. After stirring evenly, a cellulose solution can be obtained. The cellulose of the above-mentioned cellulose preferably has a degree of polymerization (DP) of 625 and a moisture content of preferably 5%. Next, the suspension is uniformly mixed with the cellulose solution to form a fiber spinning solution, wherein the weight of the cellulose solution is preferably about 0.25 to 40% by weight of the fiber spinning solution. Subsequently, a wet spinning process is carried out at a preferred temperature of 85 to 120 ° C to obtain a multi-functional Lyocell fiber. Preferably, the cellulose has a viscosity of preferably from 0.5 to 200 mPas at a temperature of preferably 90 ° C, and the degree of polymerization is preferably from 500 to 700. The multi-functional regenerated fibers of the cellulose obtained above were subjected to a woven fabric process to form a multi-functional cellulosic woven fabric, and then subjected to antibacterial, far-infrared rays and deodorization tests, respectively.
