Cov nyhuv ntawm fiber thiab ntsws
Raws li cov fibers lawv tus kheej nqus dej, lawv swell rau qee yam. Qhov o ntawm cov fibers feem ntau yog anisotropic (tshwj tsis yog nylon), uas yog, qhov ntev tau luv dua thiab txoj kab uas hla tau nce. Qhov feem pua sib txawv ntawm qhov ntev ntawm cov ntaub thiab nws qhov qub ntev feem ntau hu ua shrinkage. Lub zog muaj peev xwm nqus tau dej ntau dua, ua rau o ntau dua, qhov nqes qis dua, qhov hnyav dua qhov ruaj khov ntawm cov ntaub.
Qhov ntev ntawm daim ntaub nws tus kheej txawv ntawm qhov ntev ntawm cov xov paj (siv lo lo ntxhuav) siv, thiab qhov sib txawv feem ntau yog qhia los ntawm tus nqi ntawm kev nqaim. Weaving shrinkage (%)=[yarn (txhob lo lo ntxhuav) ntev - ntaub ntev] / ntaub ntev
Npuag hauv dej, vim qhov o ntawm cov fiber ntau nws tus kheej, qhov ntev ntawm cov ntaub yog luv dua, ua rau shrinkage. Kev nqaim ntawm ib daim ntaub nws txawv raws li nws cov ntsws. Tus nqi qis ntawm cov ntaub yog txawv nrog qhov sib txawv ntawm cov qauv ntaub thiab weaving nro. Kev sib zog ntawm cov ntaub yog me me, cov ntaub yog ntom thiab tuab, cov ntaub qhwv cov ntaub qhwv loj, cov ntaub ntawm cov ntaub me me.
Kev sib zog ntawm qhov hnyav yog qhov loj, cov ntaub yog xoob thiab lub teeb, qhov hnyav ntawm qhov hnyav yog me me, thiab qhov nqes ntawm cov ntaub yog qhov loj. Hauv cov txheej txheem zas xim thiab ua kom tiav, txhawm rau txhawm rau txo qis qis ntawm cov ntaub, kev ua kom tiav ua ntej shrinkage feem ntau siv los txhawm rau txhawm rau ntom ntom ntom ntom ntom ntom thiab txhim kho qhov nqaim ua ntej, yog li txhawm rau txo qis qis ntawm cov ntaub.
Ua rau kev nqaim
