Mechanical zog ntawm fabrics muaj xws li tensile zog thiab tawg lub zog. Lub zog tensile hais txog cov ntaub muaj peev xwm tiv taus lub zog tensile siab tshaj plaws thaum lub sij hawm ncab, thaum lub zog tawg yog qhov kev ntxhov siab ntawm cov ntaub so. Cov ntsuas no muaj kev cuam tshuam cov ntaub durability thiab load-cov kabmob muaj peev xwm. High- cov ntaub muaj zog yog tsim rau cov khaub ncaws sab nrauv, cov khaub ncaws ua haujlwm, thiab cov khoom siv sab nraum zoov, thaum cov ntaub muaj zog tsawg yog tsim rau cov khaub ncaws hnav lossis cov khoom siv zoo nkauj. Tear zog thiab abrasion kuj tseem suav nrog. Lub zog tsim kua muag qhia tias cov ntaub tiv thaiv kom tawg nyob rau hauv cov kev ntxhov siab hauv zos, thaum kev puas tsuaj los ntsuas cov ntaub muaj peev xwm tswj tau qhov kev ncaj ncees ntawm qhov chaw nyob rau hauv kev sib txhuam. Cov ntaub uas muaj lub zog tsim kua muag siab thiab ua rau muaj kev puas tsuaj yog qhov tsim nyog rau lub sijhawm ntev - hnav lossis siab - zaus siv cov xwm txheej, xws li khaub ncaws, khaub ncaws kis las, thiab hnav ua haujlwm. Weaving txoj kev, xov paj thickness, thiab ntom muaj qhov cuam tshuam loj rau cov khoom no.
Fabrics kuj muaj elasticity thiab resilience. Elasticity yog cov ntaub muaj peev xwm ncab tom qab deformed nyob rau hauv kev ntxhov siab, thaum resilience hais txog cov ntaub muaj peev xwm rov qab mus rau nws qhov qub qub tom qab raug kev nyuaj siab. Knitted fabrics feem ntau muaj elasticity zoo dua, thaum woven fabrics muaj qis elasticity. Zoo elasticity thiab resilience tsis tsuas yog xyuas kom hnav kev nplij siab, tab sis kuj tiv thaiv cov tsoos tsho deformation, wrinkles, los yog sagging, txhim kho lifespan thiab zoo nkauj.
