Abstract
Description
本發明為關於一種天然纖維素纖維（Lyocell），特別是指一種使用回收材料為原料的天然纖維素纖維。The invention relates to a natural cellulose fiber (Lyocell), in particular to a natural cellulose fiber using recycled materials as raw materials.
天然纖維素纖維（Lyocell）的製程，包括調漿、溶解、紡絲及水洗等步驟，即通常以木漿溶解於N-甲基嗎啉-N-氧化物（NMMO）溶劑，經過紡絲步驟取得原絲，並經水洗洗除殘留在原絲內的NMMO溶劑，以製成天然纖維素纖維成品。The manufacturing process of natural cellulose fiber (Lyocell) includes the steps of pulping, dissolving, spinning and washing. That is, wood pulp is usually dissolved in N-methylmorpholine-N-oxide (NMMO) solvent, and then goes through the spinning step. The raw fibers are obtained and washed with water to remove the NMMO solvent remaining in the raw fibers to produce natural cellulose fiber products.
天然纖維成品亦可分為短纖絲（Staple）與長纖絲（Filament），惟兩者製程尚有不同：短纖絲之製程包含切割、壓縮、混紗、紡線等加工程序，對於不斷裂及均勻成型的要求較低；長纖絲之製程，則須使纖維無限拉伸，故所製成之絲線須具有不易斷裂而以一步驟製成之特性，而所使用之紡絲溶液中，纖維素長鏈分子的濃度占比通常較高，使其紡絲溶液黏度相對增加，方能於產製過程中不易發生紗線斷裂之情況。由短纖絲成品之外觀粗糙、有毛羽；而由長纖絲成品之外觀亮、滑順且質地較強韌，因此兩者所適用的紡織成品亦有不同。Natural fiber finished products can also be divided into short fiber (staple) and long fiber (filament), but the two processes are still different: the staple fiber manufacturing process includes cutting, compression, blending, spinning and other processing procedures. The requirements for breaking and uniform forming are low; the process of making long filaments requires infinite stretching of the fibers, so the filaments made must be difficult to break and made in one step, and the spinning solution used , the concentration of long-chain cellulose molecules is usually high, so that the viscosity of the spinning solution is relatively increased, so that yarn breakage is less likely to occur during the production process. The appearance of products made from short-fiber yarns is rough and hairy, while the appearance of products made from long-fiber yarns is bright, smooth and stronger in texture. Therefore, the textile products suitable for the two are also different.
由於近年環保意識抬頭，綠色環境、永續經營議題備受關注，各國政府競相朝長期且環保、永續經營的目標努力，民間亦致力於「綠色產品」的開發，使產品於原料取得、生產製造、銷售、使用乃至廢棄處理過程中，能對環境無危害或危害極小，且有利於資源再生或回收利用，達到低汙染、可回收、省資源的目標。以二手衣重新製成衣服或以回收寶特瓶製成運動服均為「綠色產品」的實例。Due to the rise in environmental awareness in recent years, green environment and sustainable management issues have attracted much attention. Governments around the world are competing to work towards long-term, environmentally friendly and sustainable management goals. The private sector is also committed to the development of "green products", so that products can obtain and produce raw materials. During the manufacturing, sales, use and even disposal processes, it can cause no harm or minimal harm to the environment, and is conducive to resource regeneration or recycling, achieving the goals of low pollution, recyclability and resource saving. Clothing remade from second-hand clothes or sportswear made from recycled plastic bottles are examples of “green products”.
無論天然纖維素纖維或人造纖維產品，其於抽絲、紡紗、織布、印染、後續處理加工等一系列的紡織製程中，都對環境造成不同程度的汙染，從而，為謀求環境永續發展及節省資源，相關業者開始著手於紡織品的回收再利用或利用回收材料再製成紡織品。例如已知有利用回收衣料等獲得天然植物纖維素之方式，先將該等回收衣料粉碎，分離其中的非纖維成分與纖維成分，接續以取得的纖維素纖維製造絲線、紡織品等。Regardless of whether natural cellulose fibers or man-made fiber products, they cause varying degrees of pollution to the environment during a series of textile processes such as spinning, spinning, weaving, printing and dyeing, and subsequent processing. Therefore, in order to seek environmental sustainability In order to develop and save resources, relevant industries have begun to recycle textiles or use recycled materials to make textiles. For example, it is known to use recycled clothing to obtain natural plant cellulose. The recycled clothing is first crushed, the non-fiber components and fiber components are separated, and then the obtained cellulose fibers are used to manufacture silk threads, textiles, etc.
目前業界雖已就回收纖維材料之再利用提供若干方法，惟所製成的絲線或紡織絲品之生物可分解、親水、涼感、垂感特性仍不理想，且多用於短纖絲產品，而不適合製成長纖絲。Although the industry has provided several methods for the reuse of recycled fiber materials, the biodegradable, hydrophilic, cool and drape properties of the resulting silk threads or textile products are still not ideal, and are mostly used in staple fiber products. Not suitable for making long filaments.
本發明之主要目的，在於使用較高比例的回收纖維材料作為原料，製造生物可分解且同樣具有親水、涼感、垂感、抗靜電特性的天然纖維素纖維。The main purpose of the present invention is to use a relatively high proportion of recycled fiber materials as raw materials to produce natural cellulose fibers that are biodegradable and also have hydrophilic, cool, drapey, and antistatic properties.
為了達成上述目的，本發明提供一種具有回收纖維素之天然纖維素纖維，其使用回收纖維漿料溶解於紡絲溶液中，包括：回收纖維素於該紡絲溶液中之重量百分比為30％至55％。In order to achieve the above object, the present invention provides a natural cellulose fiber with recycled cellulose, which uses recycled fiber slurry to be dissolved in a spinning solution, including: the weight percentage of recycled cellulose in the spinning solution is from 30% to 30%. 55%.
本發明具有以下的有益效果：1. 本發明之天然纖維素纖維，可適用於長纖絲製程；2.相較於未添加回收材料所製成之天然纖維素纖維，本發明之天然纖維素纖維同樣具有親水、涼感、垂感、抗靜電、可生物分解等性質；2.本發明之天然纖維素纖維，由於使用較高比例的回收材料製成，可以幫助實現「低汙染、可回收、省資源」的環境保護、永續發展目標。The present invention has the following beneficial effects: 1. The natural cellulose fiber of the present invention can be used in long filament production processes; 2. Compared with natural cellulose fibers made without adding recycled materials, the natural cellulose fiber of the present invention The fiber also has properties such as hydrophilic, cool, drapey, antistatic, and biodegradable; 2. Since the natural cellulose fiber of the present invention is made of a higher proportion of recycled materials, it can help achieve "low pollution, recyclability, Environmental protection and sustainable development goals of "saving resources".
一般纖維可分為天然纖維與人造纖維。天然纖維存於自然之中，依據來源不同，可分為植物纖維、動物纖維與礦物纖維；而人造纖維係指經加工而製成的纖維，可以由天然原料加工而得（例如：莫代爾纖維、萊賽爾纖維等），亦可透過化學方法合成（例如：聚酯纖維、尼龍等）。General fibers can be divided into natural fibers and man-made fibers. Natural fibers exist in nature and can be divided into plant fibers, animal fibers and mineral fibers according to different sources; man-made fibers refer to processed fibers, which can be processed from natural raw materials (for example: modal fiber, Lyocell fiber, etc.), can also be synthesized through chemical methods (for example: polyester fiber, nylon, etc.).
回收纖維材料之來源可為回收天然纖維與回收人造纖維。回收天然纖維可為經處理的回收棉、回收木漿、回收紙漿、回收麻（如：回收亞麻、回收苧麻與回收黃麻）等含有天然植物纖維的回收天然纖維。該等天然植物纖維之來源，可以完全或部分地來自服裝製造殘餘物及／或舊服裝、木漿、破布漿、紡織品、服裝、棉，以節省資源並達到回收纖維材料再利用之目的。The sources of recycled fiber materials can be recycled natural fibers and recycled man-made fibers. Recycled natural fibers can be processed recycled cotton, recycled wood pulp, recycled paper pulp, recycled hemp (such as recycled flax, recycled ramie and recycled jute) and other recycled natural fibers containing natural plant fibers. The source of these natural plant fibers can come entirely or partially from clothing manufacturing residues and/or old clothing, wood pulp, rag pulp, textiles, clothing, and cotton to save resources and achieve the purpose of recycling fiber materials.
天然纖維素纖維（Lyocell）為一種人造纖維，天然纖維素纖維之製造方法通常為（1）將原生木漿纖維溶於N-甲基嗎啉-N-氧化物（NMMO）溶劑中，製成纖維素漿料；（2）透過膜擠機（Filmtruder）排放出紡絲溶液；（3）再經過紡絲、洗滌、乾燥等程序後，捲繞因此製成絲線；（4）最後將紗線織造為布帛，再進一步加工成商品應用於衣著、家具、醫療器材等在市場上銷售。Natural cellulose fiber (Lyocell) is a kind of man-made fiber. The manufacturing method of natural cellulose fiber is usually (1) dissolving native wood pulp fiber in N-methylmorpholine-N-oxide (NMMO) solvent to make Cellulose slurry; (2) Discharge the spinning solution through the film extruder (Filmtruder); (3) After spinning, washing, drying and other procedures, winding to make silk yarn; (4) Finally, the yarn It is woven into cloth and then further processed into products for use in clothing, furniture, medical equipment, etc. and sold in the market.

Traditional natural cellulose fiber products still require a large amount of natural raw materials, which easily leads to resource consumption. Therefore, the present invention provides a natural cellulose fiber with recycled cellulose. , mainly from second-hand textiles, such as recycling old clothes, furniture or other waste textiles to obtain recycled fiber materials, and using recycled fiber materials to make recycled cellulose slurry to obtain recycled cellulose.
