摘要：为了通过泡沫染色和光固化改善棉织物的染色性能，合成了一种含有不饱和双键的硅氧烷低聚物，设计
了合适的含有聚合型黄色蒽醌染料、硅氧烷低聚物、光引发剂 2,4,6-三甲基苯甲酰基-二苯基氧化膦（TPO）、表
1
面活性剂十二烷基硫酸钠（SDS）的泡沫体系对棉织物进行泡沫染色。采用 HNMR 和 GPC 分析了硅氧烷低聚
物的化学结构和相对分子质量分布，采用 FTIR 表征了硅氧烷低聚物和染色棉织物的化学结构，采用 SEM 观察染
色棉织物的表面形态。探讨了硅氧烷低聚物用量、染料用量、SDS 质量浓度、TPO 用量对泡沫性能和染色性能的
影响，分析了硅氧烷低聚物的固色机理。结果表明，染料质量浓度 30 g/L、硅氧烷低聚物用量为染料质量的 2 倍、
SDS 质量浓度 2.0 g/L、TPO 用量为染料质量的 5%、紫外光照时间 5 min 时，染色织物染色深度可达 5.70，耐皂洗
色牢度和干/湿摩擦色牢度均为 4~5 级，水接触角为 110.1°，紫外防护系数>50。硅氧烷低聚物通过侧基上的不饱和
双键发生自由基聚合和硅醇基偶合交联实现固色，并赋予织物良好的疏水性能和抗紫外线性能。

Abstract: In order to improve the dyeing performance of cotton fabric via foam dyeing and photocuring, a
siloxane oligomer containing unsaturated double bonds was synthesized and used in preparation of a
suitable foam system along with polymeric yellow anthraquinone dye, 2,4,6-trimethylbenzoyldiphenyl
phosphine oxide (TPO) as photoinitiator, and sodium dodecyl sulfate (SDS) as surfactant for foam dyeing
of cotton fabrics. The chemical structure and relative molecular mass distribution of siloxane oligomer, as
well as the chemical structure and morphology of dyed cotton fabric were characterized and analyzed by
1 HNMR, GPC, FTIR and SEM, respectively. The effects of siloxane oligomer amount, dye amount, mass
concentration of SDS, TPO amount on foam performance and dyeing performance were then investigated,
followed by analysis on the color fixation mechanism of siloxane oligomer. The results showed that the dye
depth of 5.70, both color fastness to soaping and to dry/wet rubbing of 4~5, ultraviolet protection factor >
50 and water contact angle of 110.1° were achieved when the mass concentration of dye was 30 g/L, the
amount of silicone oligomer was twice the dye mass, the mass concentration of SDS was 2.0 g/L, the
amount of TPO was 5% of the dye mass, and UV irradiation time of 5 min. The siloxane oligomer achieved
color fixation through free radical polymerization and silanol conjugate crosslinking of unsaturated double
bonds on the side group, which made the dyed cotton fabric have good hydrophobic and UV resistance.
