摘要
采用2种不同性能涤纶进行成网及水刺加固成形,研究单纤性能对水刺工艺及纤维缠结性能的影响,分析探索射流冲击对不同性能涤纶的缠结作用与规律。结果表明:纤维的缠结作用随着水刺(射流)压力的增加和输网帘速度降低而增大;相同长度和细度的纤维,其弯曲刚度小,摩擦因数大,吸水性能好,在同样的射流力度和射流冲击时间下,更易缠结;水刺材料的吸水性与纤维缠结程度及纤维吸水性有关。
Two kinds of polyester fibers with different properties were laid into web and hydroentangled respectively. The influence of fiber property on hydroentangling process and fiber entanglement was researched. The rule and action on entanglement of fibers with different properties by spraying with high speed jets of water were analyzed. The result showed that the effect of entanglement increased with increasing waterjet pressure and decreasing speed of support belt; when fibers have the same length and fineness, the fiber which has smaller bending rigidity and better hydroscopicity and bigger frictional coefficient can entangle better under the same jet spraying force and time; The hydrophilic property of spunlaced fabric is related to fiber entanglement degree and fiber hydroscopicity.
