摘 要:合成了3個(gè)含不同數目磺酸鈉基團的二苯乙烯聯(lián)苯類(lèi)熒光增白劑,利用1H NMR和紅外光譜確證了其結構。采用浸漬法對棉布和滌綸進(jìn)行增白,得到了不同濃度的增白劑對棉布和滌綸的增白效果。研究結果表明,3個(gè)增白劑均對棉布和滌綸具有較高效率的增白效果,當增白劑濃度為0.05% o.w.f和0.4% o.w.f時(shí),滌綸和棉布的白度最大可分別提升到180.592和151.733。隨著(zhù)增白劑所含-SO3Na(磺酸鈉基團)數目的增加,棉織物白度增加。然而,隨著(zhù)增白劑所含-SO3Na(磺酸鈉基團)數目的增加,滌綸織物的白度反而降低。該研究可為含-SO3Na的二苯乙烯聯(lián)苯類(lèi)增白劑在棉布和滌綸中的應用提供思路,為更好地設計與合成性能優(yōu)異的二苯乙烯類(lèi)熒光增白劑提供指導。 |

Abstract:Three stilbene biphenyl fluorescent brighteners with different numbers of sodium sulfonate groups were synthesized and their structures were confirmed by 1H NMR and IR spectroscopy. Samples of cotton and polyester were whitened by the dipping method, and the whitening effects of the agents monitored at different concentrations. The results showed that the three whitening agents had higher efficiency whitening effect on cotton and polyester. When the whitening agent concentration was 0.05% o.w.f and 0.4% o.w.f, the whiteness of polyester and cotton could be increased to 180.592 and 151.733, respectively. For cotton fabric the whiteness increases with the increased number of -SO3Na (sodium sulfonate groups). However, in the case of polyester fabric, the whiteness decreases with the increase of -SO3Na number. This study provides useful insight into the use of stilbene biphenyl brighteners that contain -SO3Na for cotton and polyester applications, and basic data for better design and synthesis of stilbene fluorescent brighteners. |
Key words:fluorescent whitening agent; sodium sulfonate group; whitening performance; whiteness |
