摘　　要：为解决采用传统的“压扁-还原”的机织方法制备三维纺织品预制体成型的局限性问题,通过深入研究织造连续性、整体性T结构预制体的成型技术,采用以正交组织为基础,通过经纱接结绑定,以机织的方法织造梁高与底面厚度相等且一次成型的T结构三维机织物。对织造工艺进行优化改进,织造了接结纱跨越不同的纬纱列数的2种T结构三维机织物,测量了不同区域的尺寸。结果表明:1个完整组织循环中,为使跨越底面区域的浮线下沉且满足织造尺寸要求,底面区域纱线数约是总纱数的一半;当纬纱跨越2个纬纱列时,织物表面的平整度和成型性更好。In order to overcome the limitation of the traditional"flattening-restoring"weaving method for preparing three-dimensional textile preforms,T-shape three-dimensional woven fabrics with specified beam height and bottom thickness and one-time forming were woven based on orthogonal organization and warp binding ensuring weaving continuity and integral T-shape preforms.Through optimizing and improving the weaving process,two types of T-shape three-dimensional woven fabrics with binding yarns spanning different weft rows were woven,and the dimensions of different areas were measured.The results show that in a complete tissue cycle,in order to sink the floating line across the bottom area and meet the fabric size requirements,the number of yarns in the bottom area is about half of the total number of yarns.Moreover,when the weft yarn spans two weft yarn rows,the evenness and formability of the fabric surface are better.
