Abstract

A series of vegetable oil-based nonionic Gemini surfactant (GPNGS) was prepared using grape seed oil and polyethylene glycol monomethyl ether (350, 550, 750) as the primary raw materials. The chemical structures of different types of GPNGS were characterised by Fourier Transform–infrared spectroscopy, elemental analysis, proton nuclear magnetic resonance and carbon-13 nuclear magnetic resonance. The critical micelle concentration (CMC) of GPNGS with different polyoxyethylene chain lengths was measured using the Wilhelmy ring method (CMC: ca. 1.4 × 10⁻⁴ to 5 × 10⁻⁴ mol/L). The results of wettability testing showed that the contact angle of GPNGS on polyamide film was ca. 46-49°. In addition, the interaction of surfactants with acid dyes was also investigated. The ultraviolet spectrum showed a balance between dyes, surfactants and the dye/surfactant complex. Next, the GPNGS was used as a nylon 66 acid dye levelling agent. After adding 0.2 mmol/L of surfactants, the standard deviations (S(λ)) of nylon 66 dyeing decreased from 0.084 to ca. 0.036-0.044, exhibiting a good levelling effect.

葡萄籽油基Gemini非离子表面活性剂的合成及应用

以葡萄籽油和聚乙二醇单甲醚（350、550、750）为主要原料，制备了一系列植物油基非离子双子座表面活性剂（GPNGS）。傅立叶变换红外光谱、元素分析、质子核磁共振和碳 13 核磁共振表征了不同类型 GPNGS 的化学结构。采用 Wilhelmy 环法测量了不同聚氧乙烯链长度的 GPNGS 的临界胶束浓度（CMC）（CMC：约 1.4 × 10-4 至 5 × 10-4 mol/L）。润湿性测试结果表明，GPNGS 在聚酰胺薄膜上的接触角约为 46-49°。此外，还研究了表面活性剂与酸性染料的相互作用。紫外光谱显示染料、表面活性剂和染料/表面活性剂复合物之间达到了平衡。接下来，GPNGS 被用作尼龙 66 酸性染料匀染剂。加入 0.2 mmol/L 的表面活性剂后，尼龙 66 染色的标准偏差（S(λ)）从 0.084 降至约 0.036-0.044，显示出良好的匀染效果。
