氨纶经编平纹布送经量的影响因素

Factors influencing let-off amount of polyurethane locknit elastic fabric

针对氨纶经编平纹织物更换品种时送经量设置困难的问题,前梳使用33、44、55 dtex的涤纶长丝、锦纶长丝,后梳使用44 dtex的氨纶丝为原料,分别在卡尔迈耶HKS2-3 E经编机和利巴COP2 KE经编机上进行上机实验。考察了牵拉密度、原料线密度及种类、机号以及机型等参数对经编弹力织物前梳送经量的影响,并利用回归分析得出各影响因素与前梳送经量的关系。结果表明,以上因素均对氨纶经编弹力织物的前梳送经量有影响;其中,牵拉密度、机号是影响前梳送经量的高度显著性因素。

In order to solve the problem on the setting of the let-off amount of polyurethane locknit elastic fabric, different specifications of fabrics were knitted using 33, 44, 55 dtex of polyester filament yarns and nylon filament yarns on 1st guide bar, while using 44 dtex polyurethane fibers as raw materials on 2nd guide bar. The effect of traction density, linear density and types of yarn, machine gauge and type on the let-off amount of warp knitted elastic fabric was investigated by experiments on the warp knitting machine with types of HKS2-3 E and COP2 KE. The relationship between structural parameters and let- off amount was found through the regression analysis. The results show that the structural parameters of traction density, linear density and types of yarn, machine gauge and type, have significant influence on the let-off amount of warp knitted elastic fabric.
