摘　　要：经过前期研究,目前已经实现使用一根自固结子线织造出带有图案的针织物,该针织物图案立体感强,织造工艺简单。为了进一步探索图案成形的影响因素以及图案的修正方法,文章以织造时的喂纱张力为研究要点,分析张力变化时图案在针织物上的变化状态以及相对应精准纺纱工艺的调整方法。结果表明,用相同纺纱工艺纺制的自固结子线进行织造,当喂纱张力为0时,喂纱口纱线抖动严重,导致张力不稳定,图案产生无规律形变;当喂纱张力变大,喂纱口纱线保持张力稳定,但图案会发生规律性的向右倾斜。文章通过实验建立出图案修正公式,并根据修正公式调整线圈长度以及纺纱工艺参数,最终得到一次成形精准图案的针织物。Based on the initial research,it can be inferred that self-consolidating knot yarn has already become an option for knitting fabrics with a three-dimensional design and a user-friendly process.To delve into the factors that influence pattern shaping and the corrective techniques for patterns,the paper centers on the primary research point of feeding tension and scrutinizes the relevant alterations in knitted patterns,in addition to the corresponding methods for precise spinning process adjustment.The findings demonstrate that implementing self-consolidating knot yarn within the identical spinning process to knit fabrics,when the feeding tension is zero,severe yarn jitter during feeding leads to unstable tension and irregular pattern deformation;while the yarn tension will be stable when increasing the feeding tension,the pattern will be tilted to the right regularly.The pattern correction formula is finally established after experiments to adjust the stitch length as well as the spinning process parameters and ultimately obtain the fully-fashioned knitted fabric with an accurate pattern.
