Description
本發明係關於呈分散形式的螢光增白劑(FWAs)之調配物，及其用於增亮織物材料之用途。
螢光增白劑(FWAs)對合成織物纖維提供顯著增白作用，但此等試劑之水性分散液之儲存穩定性通常不足，亦即在室溫下儲存數月導致分散液沈澱及混濁。
現已驚奇地發現，可藉由添加少量β-1,3-葡聚糖獲得1,2-二苯乙烯增亮劑之穩定水性分散液。添加穩定劑有助於有效控制pH值且不會不利地影響試劑之增亮活性及所處理纖維之特性。
本發明係關於一種水性分散液，其含有
(a)螢光增白劑，
(b)分散劑，及
(c)β-1,3-葡聚糖。
基本上，已知用於此目的之任何FWAs可用於本發明之水性分散液中。較佳使用二氰基-1,4-雙-苯乙烯基苯及雙苯并噁唑。
本發明因此係關於上文所述之水性分散液，其含有下式化合物作為螢光增白劑：
更佳地，本發明水性分散液含有下式化合物作為螢光增白劑：
在另一較佳具體實例中，本發明水性分散液含有下式化合物作為螢光增白劑：
其中R1表示氫、C1-C6烷基、C6-C14芳基或C7-C24芳烷基且X為式(3)、(4)或(5)之二價基團
作為R1之C1-C6烷基包括例如甲基、乙基、丙基、異丙基、正丁基、異丁基、第二丁基、第三丁基、戊基、第三戊基(1,1-二甲基丙基)、正戊基、新戊基及正己基。
C6-C14芳基之實例為苯基、甲苯基、基(mesityl)、isityl、二甲苯基、萘基、蒽基及菲基。
作為R1之C7-C24芳烷基包括例如苯甲基、2-苯基乙基、二苯基甲基、萘基甲基及2-萘基乙基。
尤其較佳的式(2)之FWAs為式(2a)及(2b)化合物
適用於本發明分散液之分散劑較佳為非離子界面活性劑。
非離子分散劑之實例為脂肪醇、較高碳數脂肪酸、烷基苯酚、山梨糖醇酯、二苯乙烯基苯酚及三苯乙烯基苯酚之環氧乙烷加合物；環氧乙烷與環氧丙烷之共聚物或乙二胺環氧乙烷/環氧丙烷加合物。
出於某種目的，本發明之水性分散液另外含有有機溶劑，例如乙二醇、丙二醇、二乙二醇、二丙二醇、聚乙二醇或聚丙二醇。
β-1,3-葡聚糖為由某些微生物對葡萄糖之作用所產生之多醣。可作為增稠劑施加於水中之適合葡聚糖揭示於例如美國專利第3,301,848號中。
較佳β-1,3-葡聚糖為硬葡聚糖(scleroglucan)。
螢光增白劑通常以兩種或兩種以上組分之混合物形式使用，因為該等混合物所展現的白度可能高於單獨之個別組分的總和。
在一較佳具體實例中，本發明之水性分散液含有包含5重量%-25重量%，尤其10重量%-20重量%式(1)化合物與75重量%-95重量%，尤其80重量%-90重量%至少一種式(2)化合物之混合物作為螢光增白劑，各百分比以全部螢光增白劑之總數計。
尤其較佳為如上文所述之水性分散液，其含有包含以下之混合物作為螢光增白劑：
2.5重量%至25重量%下式化合物
2.5重量%至20重量%下式化合物
及55重量%至95重量%下式化合物
各百分比以全部增白劑之總數計。
此外，尤其關注含有以下之水性分散液：
(a)5重量%-40重量%，尤其10重量%-30重量%螢光增白劑，
(b)0.5重量%-15重量%，尤其1.0重量%-10重量%分散劑，及
(c)0.5重量%-10重量%，尤其1.0重量%-5.0重量% β-1,3-葡聚糖，
各百分比以分散液之總重量計。
式(1)及式(2)化合物為熟知之FWAs且市場有售，或可根據熟知方法製備。
本發明之另一目標為藉由以上文所述之水性分散液處理來增亮織物材料之方法。
本發明之另一目標為使用如上文所述之水性分散液增亮合成纖維，尤其聚酯纖維。
依照螢光增白劑之混合物的慣例，可藉由將個別組分分散於液體介質(較佳水)中，將其加工成市售形式。此可藉由分散個別組分，接著組合所獲得之分散液進行。然而，亦可將個別組分基本上混合在一起，接著使其共同分散。分散操作可在球磨機、膠磨機、珠磨機或其類似機器中以習知方式進行。
較佳，FWAs與水及分散劑組合在一起在玻璃珠粒存在下濕磨。所得研磨儲備料可儲存，分成不同部分且以本身已知之方式加工。
本發明之水性分散液可另外含有0.1重量%至60重量%，較佳5重量%至50重量%助劑。
適合助劑包括例如濕潤劑、防凍劑、消泡劑、增稠劑/穩定劑及殺生物劑。
增稠劑/穩定劑之實例為N-乙烯基吡咯啶酮與3-乙烯基丙酸之共聚物、聚乙烯醇或非離子/陰離子多醣。
各種類型之調配助劑描述於McCutcheon之乳化劑與清潔劑以及功能材料年鑒(McCutcheon's year books of Emulsifiers & Detergents and Functional Materials)中。
本發明之水性分散液及含有其之組成物適於增白由合成纖維製成之織物材料，尤其由聚酯製成之織物材料。然而，此等混合物及組成物亦可用於增白含有聚酯之摻合物。
本發明混合物藉由通常用於施用螢光增白劑之方法，例如藉由在染色機中之盡染法(exhaust dyeing process)或藉由壓吸熱固色(pad-thermofixation)施用。便利地在水性介質中進行處理，化合物以精細微粒形式存在於該水性介質中，形成懸浮液、微分散液，或視情況形成溶液。若適當，在處理期間可添加分散劑、穩定劑、濕潤劑及其他助劑。處理通常在約90℃至140℃，較佳110℃至130℃之溫度範圍內進行。若藉由壓吸熱固色法施用混合物，則熱固色較佳在170℃至200℃之溫度下進行。
本發明之水性分散液在不添加調色染料(shading dyes)之情況下即提供藍色色調。
此外，以本發明水性分散液處理之材料展現高耐光性以及高白度及卓越亮度。
已驚奇地發現，β-1,3-葡聚糖不僅為FWAs分散液之有效穩定劑，而且亦為含有甕染料及FWAs之分散液的有效穩定劑，含有甕染料及FWAs之分散液適於增白具有色調變化之聚丙烯腈(PAN)纖維。
因此，本發明另外係關於一種水性分散液，其含有
(a)螢光增白劑，
(b)分散劑，
(c)β-1,3-葡聚糖及
(d)甕染料。
熟習此項技術者已知可施用於PAN纖維之FWAs。適合增亮劑為例如苯并咪唑衍生物，如C.I.螢光增亮劑363。
適於PAN染色之甕染料同樣為此項技術所熟知。實例為C.I.甕紫1及C.I.甕藍66。
本發明另外係關於增亮織物材料之方法，其藉由以如上文定義之含有組分(a)+(b)+(c)之水性分散液或含有組分(a)+(b)+(c)+(d)之水性分散液處理。
本發明另外係關於如上文定義之含有組分(a)+(b)+(c)之水性分散液或含有組分(a)+(b)+(c)+(d)之水性分散液的用途，其用於增亮合成纖維。
