Description
本發明係有關一種色彩辨識之方法，尤其是一種利用樣本頻譜母色溯源之方法。 The present invention relates to a method of color identification, particularly a method of tracing the source of parent colors using sample spectrum.
早在公元前2500年前已開始運用自然界植物、動物和礦物精華等之染料，在1856年英國化學家柏金(W.Perkin,1838-1907)發明第一個合成染料(mauveine)之前，所有染料都是取自天然，來自於植物、動物與礦物，例如取自於植物的根、樹皮、葉子、花果或木料。而染料製作方式乃經由簡易加工方式，例如：搗碎材料、研磨即可製成天然染料，並廣泛應用於紡織之染色加工，較為常見之方式為染浴方式，即天然染料被投入大鍋中與沸水熬煮，並將欲染色之紡織布料與固色劑投入另一大鍋中煮沸處理後，投入染料鍋中，取出晾乾後再清洗即完成染料上色。而，天然染料傳承至近代，開始有業者利用化石資源合成出合成染料，例如：石油，將石油分餾成煤焦油並製成合成染料。 As early as 2500 BC, dyes from natural plants, animals and mineral essences have been used. Before the British chemist W. Perkin (1838-1907) invented the first synthetic dye (mauveine) in 1856, all dyes Dyes are naturally derived from plants, animals and minerals, such as plant roots, bark, leaves, flowers, fruits or wood. The dye production method is through simple processing methods, such as pounding materials and grinding to make natural dyes, which are widely used in textile dyeing processing. The more common method is the dye bath method, that is, natural dyes are put into a large pot and mixed with Boil boiling water, put the textile fabric to be dyed and the fixing agent into another large pot, boil it, put it into the dye pot, take it out to dry and then wash it to complete the dye coloring. However, natural dyes have been passed down to modern times, and some people have begun to synthesize synthetic dyes using fossil resources, such as petroleum. Petroleum is fractionated into coal tar and made into synthetic dyes.
國內染化廠約200餘家，數位印花廠約100餘家，90%屬於中小型企業，染料通常溶於水中，一部份的染料需要媒染劑使染料能黏著於纖維上。在布料染化製程，在對色步驟中，傳統染化工藝須重度倚賴人工經驗法則，導致往往需要經歷多次追色(修色)，造成大量水資源的浪費，如上萬噸染化廢水。 There are about 200 domestic dyeing factories and about 100 digital printing factories, 90% of which are small and medium-sized enterprises. Dyes are usually dissolved in water, and some dyes require mordants to make the dyes adhere to the fibers. In the fabric dyeing process, in the color matching step, the traditional dyeing process relies heavily on manual rules of thumb, which often requires multiple color chasing (color correction), resulting in the waste of a large amount of water resources, such as tens of thousands of tons of dyeing wastewater.
染化製程中，通常由染化公司之化驗室提出配方及製程資料，交由染化工廠依配方及製程試染，並設定染化製程參數，以進行量產之染化製程，若在驗色階段發現測試樣本出現色差、顏色不均、波紋、固色率未達對色率標準或上述之組合之不良品，需染化製程再增加漂洗、補色等步驟，以補強不良品之 情況，或直接報廢不良品。染化製程中所產生之不良品影響生產成本甚鉅。染化製程中許多的製程因子會影響布料染色後之對色率，如染劑濃度、助劑濃度、初始pH值、浴比值、主泵浦速率、帶布輪速率、升溫速率、持溫溫度、水洗時間、皂洗升溫速率、皂洗持溫溫度、皂洗時間等。且，傳統染化製程上，平均製作1碼樣布需用到最小規格染缸(3公斤布)，需要耗用水約1噸，舉例來說：深色(黑、藍)20公斤的染布需要使用6~7噸水，廢水處理費約新台幣1,000元/噸，若廠內無廢水處理槽，則需委外處理費用高達10,000元/噸，倘若再增加漂洗、補色等步驟，則廢水處理費用會再增加，如此傳統染化製程造成成本昂貴，產業負擔大，急需導入智慧化的對色技術來解決問題。 In the dyeing process, the dyeing company's laboratory usually provides the formula and process information, and then submits it to the dyeing factory to test dye according to the formula and process, and set the dyeing process parameters for mass production of the dyeing process. During the dyeing stage, it is found that the test sample has color difference, uneven color, ripples, color fixation rate that does not meet the color rate standard, or a combination of the above-mentioned defective products. The dyeing process needs to add steps such as rinsing and color replenishment to strengthen the defective products. situation, or directly scrap the defective products. The defective products produced during the dyeing process have a huge impact on production costs. Many process factors in the dyeing process will affect the color matching rate of the fabric after dyeing, such as dye concentration, auxiliary concentration, initial pH value, liquor ratio, main pump speed, belt wheel speed, heating rate, and holding temperature. , washing time, soaping heating rate, soaping temperature holding temperature, soaping time, etc. Moreover, in the traditional dyeing process, the average production of 1 yard of sample cloth requires the smallest size dye vat (3 kg of cloth) and consumes about 1 ton of water. For example: 20 kg of dark-colored (black, blue) dyed cloth It needs to use 6~7 tons of water, and the wastewater treatment fee is about NT$1,000/ton. If there is no wastewater treatment tank in the factory, the cost of outsourcing is as high as NT$10,000/ton. If steps such as rinsing and color replenishment are added, the wastewater The processing costs will continue to increase, making the traditional dyeing process expensive and burdening the industry. There is an urgent need to introduce intelligent color matching technology to solve the problem.
