(3) Lub zog tawg
Kev tawg lub zog qhia qhov siab tshaj plaws uas daim ntawv tuaj yeem tiv taus, feem ntau qhia hauv kPa. Lub variation nkhaus ntawm daim ntawv tawg lub zog yog zoo ib yam li qhov tawg ntev. Lub ntsiab yam tseem ceeb cuam tshuam rau lub zog tawg yog qhov sib txuas ntawm cov fibers thiab qhov nruab nrab ntev ntawm fibers, ua raws li lub zog ntawm cov fibers lawv tus kheej thiab interweaving mob ntawm fibers, thiab lwm yam. Raws li ib tug tseem ceeb carrier rau daim ntawv sib sau, lub mesh qauv ntawm daim ntawv tshuab Plain Fabric yuav ncaj qha cuam tshuam rau interweaving uniformity ntawm fibers, yog li muaj ib tug tseem ceeb lub zog ntawm bursting.
Thaum daim ntawv tawg, nws tsis yog tsuas yog raug lub zog tensile tab sis kuj tearing quab yuam. Thaum lub℃ntawm pulping kuj siab, raws li qhov nruab nrab ntev ntawm cov fibers txo, lub bursting zog nkhaus poob ntau sai tshaj qhov tawg ntev nkhaus. Nws yog ib qho tsim nyog sau cia tias siab - Daim Ntawv Tshuab Plain Fabric tuaj yeem txo qhov kev poob qis mus rau qee qhov thiab txhim kho qhov ruaj khov ntawm daim ntawv tawg los ntawm kev ua kom zoo dua cov fiber ntau.
(4) Folding endurance
Folding endurance yog hais txog tus naj npawb ntawm lub sij hawm ib daim ntawv tuaj yeem tiv taus 180℃reciprocating folds nyob rau hauv ib qho kev nro. Cov huab cua permeability uniformity ntawm Daim Ntawv Tshuab Plain Fabric yuav cuam tshuam rau cov khoom ya raws thaum lub sij hawm ziab ntawm daim ntawv, thiab qhov sib xws ntawm cov khoom ya raws yog ze ze rau elasticity ntawm fibers. Yog li ntawd, nws tsis ncaj qha cuam tshuam rau folding endurance kev ua tau zoo ntawm daim ntawv.
Cov yam ntxwv cuam tshuam rau folding endurance muaj xws li qhov nruab nrab ntev ntawm fibers, lub zog ntawm cov fibers, kev npaj ntawm fibers nyob rau hauv daim ntawv, lub zog thiab elasticity ntawm cov fibers lawv tus kheej, thiab lwm yam. Kev cuam tshuam ntawm fiber ntau lub zog ntawm folding endurance tsis yog qhov tseem ceeb raws li qhov ntev ntawm kev tawg, tab sis qhov nruab nrab fiber ntau muaj qhov cuam tshuam loj heev rau folding endurance. Yog li ntawd, qhov tig ntawm qhov folding endurance nkhaus tshwm ua ntej tshaj qhov ntev ntawm qhov tawg, uas yog, thaum lub pulping℃tsis siab heev, folding endurance pib poob.
Folding endurance tsis yog tsuas yog cuam tshuam los ntawm kev sib khi quab yuam ntawm fibers thiab qhov nruab nrab ntev ntawm fibers, tab sis kuj muaj feem xyuam rau elasticity ntawm fibers, thiab elasticity yog ze ze rau cov dej noo ntawm daim ntawv. Tsis pub dhau ib qho, ua kom cov dej noo ntawm daim ntawv tuaj yeem txhim kho cov softness ntawm fibers thiab zoo txhim kho daim ntawv folding endurance. Txawm li cas los xij, thaum cov ntsiab lus noo noo nce mus rau ib qho twg, qhov folding endurance yuav poob vim qhov txo qis hauv kev sib khi ntawm fibers. Txhawm rau txhim kho folding durability ntawm Daim Ntawv, thaum lub sij hawm pulping, yuav tsum tau them nyiaj mloog kom paub tseeb tias cov fibers muaj qhov o zoo thiab tsim fiber ntau, thiab txiav cov nyhuv ntawm cov fibers yuav tsum zam kom ntau li ntau tau. Yog li ntawd, nws yog advisable siv lub teeb riam rau pulping. Nyob rau tib lub sijhawm, siab- Daim Ntawv Tshuab Plain Fabric yuav tsum tau siv ua ke kom ntseeg tau tias muaj kev sib cuam tshuam ntawm cov fibers, thiab daim ntawv ntawv yuav tsum tiv thaiv kom tsis txhob qhuav dhau. Kev tuav cov dej kom tsim nyog ua rau cov fibers hloov tau thiab cov nplooj ntawv muaj qhov zoo folding endurance.
