中文摘要 | 一系列非離子封鎖型水性PU乃是以共聚己二酸丁二醇己二醇酯(CPBHA)、聚乙二醇(PEG)及聚丙二醇(PPG)為多元醇,並利用長EO側鏈的聚二醇醚[(EO)n]做為非離子型內化劑與二環已基甲烷-4,4'-二異氰酸鹽(H12MDI),先進行加成反應形成聚氨基甲酸乙酯預聚物再以ε-聚醯胺系封鎖劑(ε-HA)及丙二酸二乙酯(Diethyl malonate)進行封鎖反應,最後以蒸餾水進行分散成封鎖型水性PU分散液。 本系列水性PU分散液配合各種加工助劑,以傳統Pad-dry-cure之加工方式,應用於100%棉織物之防皺加工整理,其產品之抗皺角度可達290度、強力保持率70%以上、游離甲醛含量100ppm以下、耐磨損牢度400次以上及DP評級3.8級。 |
英文摘要 | A series of non-ionic blocked aqueous polyurethanes(PU) were Synthesized from the polyaddition of 4,4'-methylenebis (cyc1ohexyl- isocyanate)(H12MDI) with polyols such as Copolybutylene hexylene adipate (CPBHA), Polyethylene glycol(PEG) and polyproplyene glycol(PPG), and polyether diol [(EO)n] with long EO side chains served as an internal emulsifier. The obtained polyurethane prepolymers were then blocked with polyamide (ε-HA) and diethyl malonate type and then dispersed with distilled water to afford blocked aqueous polyurethane. The blocked aqueous polyurethanes were formulated with processing additives to achieve wrinkle-resistant application for 100% cotton fabric through pad-dry-cure procedure. The wrinkle recovery angles and strength retention and wear-fastness were above 290° and 70% and 400, respectively. The content of free formaldehyde and durable press (DP) was below 100ppm and 3.8. |
