Description
本發明係一種利用天然咖啡油脂製備功能性薄膜的方法及其紡織品。The present invention is a method for producing a functional film using natural coffee fat and a textile thereof.
長久以來，咖啡渣被看作是咖啡飲品製成之後的垃圾，其處理方式則以固態廢棄物進行土壤掩埋，對於咖啡渣並未能妥善利用。目前，如一種習知技術中華民國發明專利公告第I338729號，係利用咖啡渣進行紡織品的應用，其揭示咖啡渣含有油脂，為了提高紡織品製程良率，咖啡渣須經去除有機成分的前處理，在該過程中，二次廢棄物如咖啡油的產生且無法有效利用，需花費成本處理該廢棄物，若不處理勢必造成環境的衝擊。因此廢棄咖啡油的回收與利用，在環保議題抬頭下相對重要。For a long time, coffee grounds have been regarded as garbage after the production of coffee drinks. The treatment method is to bury the soil with solid waste, and the coffee grounds have not been properly utilized. At present, as a conventional technology, the Republic of China invention patent publication No. I338729, the use of coffee slag for textile applications, which reveals that the coffee slag contains grease, in order to improve the textile process yield, the coffee slag must be pretreated by removing organic components. In this process, secondary waste such as coffee oil is produced and cannot be effectively utilized, and it is costly to treat the waste, and if it is not treated, it will inevitably cause environmental impact. Therefore, the recycling and utilization of discarded coffee oil is relatively important under the rise of environmental issues.
生質原料概括以天然產物之原料取得而利用，包括直接從天然植物取得(如玉米、棕櫚、黃豆等)，或是利用天然植物使用後之廢棄物取得(如咖啡渣、稻桿、廢棄木材等)。然，利用天然植物之廢棄物，則不會有食物衝突的問題。上述之習知技術已揭示利用咖啡渣進行紡織品的應用，倘若咖啡渣中所含有的咖啡油能回收與再利用，以減少二次廢棄物的產生，亦能將其轉成生質原料之一環，對於環境之衝擊係相對有幫助。Biomass raw materials are generally obtained from the raw materials of natural products, including directly obtained from natural plants (such as corn, palm, soybeans, etc.), or obtained from natural plant waste (such as coffee grounds, rice straw, waste wood). Wait). However, the use of natural plant waste will not cause food conflicts. The above-mentioned prior art has disclosed the use of coffee slag for textile applications. If the coffee oil contained in the coffee slag can be recycled and reused to reduce the generation of secondary waste, it can also be converted into a ring of raw materials. It is relatively helpful for the impact of the environment.
另一方面，一般習用之機能性布料，為了達到防水透濕的功能，過去通常係使用塗佈或貼合的技術達成，藉由膠體成膜後所提供的親 水性及成膜連續性達到防水透濕的效果。On the other hand, in general, functional fabrics have been used in the past to achieve the function of waterproofing and moisture permeable, which is usually achieved by coating or laminating techniques, and the pros provided by colloidal film formation. Water-based and film-forming continuity achieves waterproof and moisture permeable effects.
目前防水透濕薄膜所使用化學製品如聚胺酯(Polyurethane)，其係經由石油化學經人工合成產生。聚胺酯為聚酯(polyester)或聚醚(polyether)多元醇和二異氰酸鹽(diisocyanate)與較小分子之鏈延長劑所反應而形成之線性崁段聚合物(liner blocked copolymer)。其中包含了兩種鏈段，一為軟質鏈段(soft segment)：是由聚酯、聚醚或聚胺基二醇和二異氰酸鹽所組成。另一為硬質鏈段(hard segment)：是由芳香族(aromatic compounds)或脂肪族(aliphatic compounds)組成之二異氰酸酯和低分子量之鏈延長劑所組成。Chemicals such as Polyurethane, which are currently used in waterproof and moisture permeable films, are produced synthetically by petrochemicals. Polyurethane is a linear blocked copolymer formed by the reaction of a polyester or polyether polyol and a diisocyanate with a chain extender of a smaller molecule. It contains two segments, one is a soft segment: it consists of polyester, polyether or polyamino diol and diisocyanate. The other is a hard segment: a diisocyanate composed of an aromatic compound or an aliphatic compound and a low molecular weight chain extender.
有鑑於組成聚胺酯的原料係由石油提萃取得，市面上因應環保趨勢發展出的環保性天然多元醇產品，乃利用天然玉米與黃豆為原料部分取代上述化學製品中的多元醇，製造出含有天然成分的聚胺酯型聚合物。而使用的原料來源卻為人類食物鏈中的一環。習知專利如US 7786239、US 7674925、US 7696370、US 6433121使用黃豆油脂製作天然多元醇。由於黃豆油脂之不飽和脂肪酸含量高達84%，較咖啡油脂之54.6%高，所以使用咖啡油生產多元醇其烴值(OH value)較黃豆油多元醇低，勢必影響後續PU合成進行之反應度，造成咖啡油多元醇無法完全導入至PU主鏈中等問題。In view of the fact that the raw materials constituting the polyurethane are extracted from petroleum, the environmentally-friendly natural polyol products developed on the market in response to environmental protection trends are made by using natural corn and soybean as raw materials to partially replace the polyols in the above-mentioned chemicals to produce natural products. A polyurethane-based polymer of the composition. The source of raw materials used is a part of the human food chain. Conventional patents such as US Pat. No. 7,786,239, US Pat. No. 7,674,925, US Pat. No. 7,696,370, US Pat. Because the unsaturated fatty acid content of soybean oil is as high as 84%, which is higher than 54.6% of coffee oil, the use of coffee oil to produce polyol has lower hydrocarbon value (OH value) than soybean oil polyol, which will affect the reactivity of subsequent PU synthesis. This caused the problem that the coffee oil polyol could not be completely introduced into the PU main chain.
因此如何有效利用天然的廢棄物來達到資源再利用的目標是為現今最需要研究的課題。Therefore, how to effectively use natural waste to achieve resource reuse is the most important topic for research today.
有鑒於過去紡織品利用化學製品所造成環境汙染缺點及廢棄物如何回收再利用的議題，本發明研究咖啡渣萃取之油脂經過純化、改質、合成的聚胺酯，並將其進一步應用於機能性紡織品防水透濕技術上。本發明內容中利用咖啡油多元醇合成PU時，採分批導入之方式使咖啡油分子取代27%石油化學之分子，可避免咖啡油多元醇無法完全導入至PU主鏈中等問題。In view of the problem of environmental pollution caused by textiles using chemicals in the past and how to recycle and reuse waste, the present invention studies the purified, modified and synthesized polyurethane of coffee residue extracted oil, and further applies it to functional textile waterproofing. Moisture permeable technology. In the present invention, when a PU is synthesized by using a coffee oil polyol, the coffee oil molecule is substituted for 27% of the petrochemical molecule by batch introduction, and the problem that the coffee oil polyol cannot be completely introduced into the PU main chain can be avoided.
本發明係利用咖啡油脂製備咖啡多元醇，並透過異氰酸酯合成聚胺酯，進一步塗佈於咖啡紗(中華民國發明專利公告第I338729號)製成之布疋上而形成之咖啡紡織品，所有紡織品之原料均採用廢棄咖啡渣為原料而製成。本發明之咖啡紡織品經功能性測試，其透氣度、透濕性防水性均達一般紡織品功能性要求，pH值測試並未造成人體皮膚之不適，塗佈之聚胺酯無剝離之問題。The invention utilizes coffee fat to prepare a coffee polyol, and synthesizes polyurethane through isocyanate, and further coats the coffee textile formed on the fabric made of coffee yarn (Republic of China Patent No. I338729), and all the raw materials of the textile are Made from waste coffee grounds. The coffee textile of the invention has functional tests, and its air permeability and moisture permeability are both functional requirements of general textiles. The pH test does not cause discomfort to human skin, and the coated polyurethane has no problem of peeling.
另一方面，廢棄咖啡中之油脂其組成為棕櫚酸與亞麻油酸組成之三酸甘油脂為主，油脂中之不飽和雙鍵先經環氧化後再經水解使其帶有氫氧基之烷類化合物，該氫氧基之烷類化合物可用來取代聚胺酯合成之軟鍊段部份，除保留一般聚胺酯之特性外，本發明之聚胺酯亦符合全球環保產品之規範。On the other hand, the oil in the waste coffee is composed mainly of triglyceride composed of palmitic acid and linoleic acid, and the unsaturated double bond in the fat is first epoxidized and then hydrolyzed to have a hydroxyl group. The alkane compound, the alkane compound of the hydroxyl group can be used to replace the soft segment portion of the polyurethane synthesis. In addition to retaining the characteristics of the general polyurethane, the polyurethane of the present invention is also in compliance with the specifications of global environmental protection products.
