纬编间隔织物的制备及其厚度影响因素分析

Preparation of weft knitted spacer fabric and analysis of factors affecting its thickness

为探讨纬编间隔织物应用于缓冲材料的结构可设计性,设计了7种间隔织物,并不断调整上机参数在电脑横机上制备样品。分析间隔方式、单丝直径和纱线配置等设计变量对间隔织物厚度的影响。通过对间隔层横截面仿真图的简化,建立单丝倾斜状态的结构模型,得出编织参数和间隔织物厚度的关系式。实际生产中可以根据间隔织物的厚度范围设计适宜的调整方案。结果表明:表面纱为弹力纱对间隔丝的厚度有积极影响,在一定范围内间隔丝的集圈隔针距及直径的增加可使织物更厚。

To explore the structural designability of weft knitted spacer fabrics used as cushioning materials,7 types of spacer fabrics are designed and samples are prepared on a computerized flat knitting machine by continuously adjusting the machine parameters.The influence of design variables such as spacing method,monofilament diameter,and yarn configuration on the thickness of spacing fabrics is analyzed.By simplifying the simulation diagram of the cross-section of the interlayer,a structural model of a single filament inclined state is established,and the relationship between weaving parameters and the thickness of the interval fabric is obtained.On this basis,suitable adjustment plans can be designed according to the thickness range of the spacing fabric in actual production.The results indicate that when the surface yarn is elastic,it has a positive impact on the thickness of the spacer wire.Within a certain range,an increase in the spacing and diameter of the spacer wire can make the fabric have a greater thickness.
