针对当前纺织品颜料数码印花存在的问题,提出将纺织品颜料数码印花技术与蓝光固化技术相结合,以实现安全、高效、环保以及具有广泛织物适应性的纺织品印花新技术。为满足颜料数码印花墨水固化膜对柔性、弹性和强度的要求,研究墨水中低聚物和单体的结构与蓝光固化共聚膜物理机械性能的构效关系,确立和优化了适用于蓝光固化技术的颜料数码印花墨水的三组分聚合体系构成(SM 6202/丙烯酸异冰片酯/丙烯酸羟乙酯的质量分数为60∶30∶10)。蓝光固化颜料数码印花的模拟实验表明:喷印过程流畅,织物上的印花图案线条精细、轮廓清晰、颜色鲜艳且手感柔软,其耐干、湿摩擦色牢度分别可达4级和4~5级。
In view of the problems existing in textile pigment digital printing,a new textile printing technology which combines pigment digital printing technology and blue light curing technology was proposed to achieve safety,efficiency environmental protection and extensive fabric adaptability.To meet the requirements of ink immobilizing membrane of pigment digital printing for flexibility,elasticity and strength,structure-function relationship between the structure of oligomer and monomer in ink and physical mechanical properties of blue light curing copolymerization membrane was studied to establish and optimize the composition of three-component polymerization system of pigment digital printing ink applicable to blue light curing technology(mass fraction of SM 6202/isobornyl acrylate/hydroxyethyl acrylate is 60:30:10).The simulation experiment of blue light curing and pigment digital printing shows inkjeting process is smooth;painted pattern o nthe fabric has fine line,clear outline,bright color and soft hand feeling;the dry and wet rubbing fastness can reach Level 4and Level 4-5.
