Lub peev xwm ntawm Jacquard ris tsho hauv qab elastic band tuaj yeem tiv taus ntau yam ntxhua yam tsis poob elasticity nyob ntawm ntau yam.
Qhov zoo ntawm cov khoom siv elastic yog qhov tseem ceeb. High-zoo elastics feem ntau yog ua los ntawm cov polymers siab heev uas yog tsim los tiv thaiv degradation los ntawm cov neeg kho tshuab kev nyuaj siab thiab tshuaj lom neeg ua hauj lwm nyob rau hauv lub txheej txheem ntxuav. Cov elastics no muaj cov qauv molecular ruaj khov, tso cai rau lawv khaws lawv cov stretchiness txawm tias tom qab rov raug dej, detergents, thiab agitation.
Cov txheej txheem tsim khoom kuj tseem ua lub luag haujlwm tseem ceeb. Yog hais tias lub elastic band yog knitted zoo los yog woven thaum lub sij hawm lub Jacquard ntau lawm, nrog rau txoj cai nro thiab ceev, nws muaj feem xyuam rau nws txoj kev ncaj ncees. Ib qho zoo-tsim elastic yuav muaj cov fibers sib npaug sib npaug uas tuaj yeem tiv taus lub zog zoo dua thaum ntxuav.
Nws tsis yog hais txog elastic nws tus kheej. Cov kev ntxhua khaub ncaws tseem ceeb heev. Siv cov tshuaj ntxuav tes maj mam, dej txias lossis dej sov, thiab tsis txhob muaj kev sib tw hnyav tuaj yeem ua rau txhua tus tuaj yeem ua rau khaws cov elasticity. Cov tshuaj hnyav hnyav thiab kub siab tuaj yeem rhuav tshem cov elastic fibers sai dua.
Txawm hais tias ntau Jacquard ris tsho hauv qab elastic bands tau tsim los ua kom huv thiab tswj lawv cov elasticity rau tus lej tsim nyog, nws tsis yog qhov kawg. Nyob rau tib lub sijhawm, nrog kev rov ua dua thiab tsis tsim nyog, qee qhov poob ntawm elasticity yog qhov kev zam. Tab sis nrog kev saib xyuas kom zoo thiab kev siv cov hlua khi zoo, lawv tuaj yeem tiv taus ntau qhov ntxhua thiab txuas ntxiv ua kom haum rau cov ris tsho hauv qab, kom ntseeg tau tias nws ua haujlwm thiab kev nplij siab rau cov neeg hnav.
