摘要
匀染剂FK-463具有良好的润湿渗透性和耐酸性,可以改善羊毛的润湿性能,使染料容易上染羊毛的疏水性部分而提高匀染性;在室温条件下,FK-463能与染料分子形成一定程度的缔合,使染液的最大吸收波长向低波长移动。FK-463用量较少时即可起促染作用,用量较多时促染作用减弱,缓染作用加强。FK-463还具有良好的匀染性、移染性,基本不影响织物的表面色深和染色牢度,达到了同类产品Albegal B的水平。
Leveling agent FK-463 features good wettability, penetrability and acid resistance. It can improve the wettability of wool fiber so that dyeability of hydrophobic part of wool fiber is enhanced and good levelness is obtained. FK-463 can aggregate with dyestuff molecules in a certain degree at room temperature, which makes a blue shift in the maximum absorption wave-length of dye liquid. FK-463 can act as an accelerating agent in small dosage, while in large dosage, it will act as a retarding agent. Leveling agent FK-463 has good migration property with no influence on color depth and fastness, which can reach the same effect as that of Albegal B.
