摘要
为在织物表面构建高含量、低厚度的颜料复合涂层,将八甲基环四硅氧烷(D4)引入颜料/单体分散液中,通过细乳液聚合制得包含有机颜料颗粒(PB)和聚二甲基硅氧烷(PDMS)的含硅颜料胶囊,并将其用于涤纶平纹织物的涂料印花。研究D4质量分数对织物表面胶膜形貌和附着形式的影响,并对印花织物的干湿摩擦牢度、K/S值、硬挺度等性能进行测试比较。结果表明:当D4质量分数为50%时,可制得平均粒径为170nm,放置均匀稳定的深蓝色胶囊乳液;在细乳液聚合过程中,部分D4开环聚合成PDMS,起到共混改性复合胶膜的效果,可提高印花织物的摩擦牢度和色深性,同时大幅降低硬挺度;在胶囊制备过程中引入D4,可在不影响颜料分散状态的前提下,通过涂覆及高温烘焙手段在织物表面构建薄型复合涂层。
In order to build a high-pigment mass fraction low-thickness organosilicone-modified composite film coating on the fabric surface, octamethylcyclotetrasiloxane (D4) was introduced into the pigment/monomer dispersion, then a silicone pigment capsules containing organic pigment particles (PB) and polydimethylsiloxane(PDMS) were prepared by miniemulsion polymerization. These pigment capsule emulsions were used in the pigment printing of polyester plain weave fabrics. The influence of D4 content on the morphology of fabric surface film was studied. The dry and wet rubbing fastness, K/S value, and stiffness of the printed fabric were tested and compared. The results show that when the mass fraction of D4 is 50%, a uniform and stable latex dispersion with an average particle size of 170 nm can be obtained. The investigation of the film morphology reveals that during the miniemulsion polymerization, part of D4 is ring-opened and polymerized into PDMS, which can be adopted to blend and modify the composite film. The corresponding pigment printing fabric has high rubbing fastness, low stiffness, and good color depth. It is believed that the introduction of D4 in the capsule preparation process can effectively increase the pigment mass fraction and water resistance of the composite film, and reduce the coefficient of friction on the surface of the film without affecting the dispersion state of the pigment.
