平缝作业下缝纫线用量的研究

Sewing Thread Consumption in Lockstitch Sewing Process

缝纫线是服装辅料中消耗量较大的原料,合理计算缝纫线用量,既便于服装成本的核算,又加强生产管理的计划性与科学性,同时也有利于服装质量管理。针对7种不同厚度的服装面料进行1.01缝型的平缝测试,归纳出不同厚度面料的平缝用线量消耗比,并对影响平缝用线量的因素进行了分析,所得结论为:在面料相同的前提下,针码密度与用线量呈反比;在a(细线)线的情况下,面线缝线消耗比的倍数关系几乎都在1.5倍以下,在c线(粗线)的情况下,面线缝线消耗比的倍数关系大部分在1.5倍以上;同种条件下,c线比a线的消耗量大,并且经向用线消耗略大于纬向,c线经向消耗量是a线的1.47倍,c线纬向消耗量是a线的1.32倍。

Sewing thread is one of the complementary materials that are consumed more in clothing production. To reasonably calculate the consumption of sewing thread is both helpful to accounting the clothing cost and improving the management, as well as controlling the clothing quality. A lockstitch sewing test with 1. O1 joint was performed on seven kinds of cloth with different thickness. The thread consumptions were compared and the factors affecting the consumption were analyzed. The conclusions are as following： given the same cloth, stitch density is inversely proportional to thread consumption ; given thin thread, the consumption of surface thread is almost less than 1.5 times as much as the sewing thread, while more than 1.5 times for thick thread ; under the same condition, the consumption of thick thread is more than that of thin thread, and the warp - wise thread consumption is higher than width -wise. The warp - wise thread consumption of the thick thread is 1.47 times as much as that of the thin thread, while its width -wise consumption is 1.32 times as much as the thin one.
