Cov Qauv Txheej Txheem Ntawm Nylon Staps Fibers

1. Molecular qauv:
Cov saw saw tseem ceeb: lub ntsiab tseem ceeb ntawm nylon staple fibers muaj cov pab pawg rov qab ua ({}}-). Cov pab pawg no pab tau cov hlua khi uas muaj zog muaj zog ua kom muaj cov nylon staple fibers dua lub zog, hnav tsis kam thiab muaj cua sov tsis kam.
Sab saw hlau qauv: nws sab saw kuj yooj yim, feem ntau yog qee pab pawg me me lossis lwm pawg yooj yim. Sab saw cov qauv muaj qee yam cuam tshuam rau solubility, kev nqus dej thiab lwm yam khoom ntawm cov nylon staps fibers. Piv txwv li, cov saw luv luv yuav ua rau Nylon staple fiber ntau soluble nyob rau qee cov kuab tshuaj; Thaum me ntsis txoj sia ntev dua yuav ua rau cov fydrophobicity ntawm cov fibers.
Cov Qauv Sau Npe:
Crystallinity: Nylon staple fibers muaj qib siab ntawm crystallinity. Hauv thaj av crystalline, cov molecular chains yog npaj tsis tu ncua thiab nyuaj rau lub zog muaj zog thiab hardness hauv macroscopic kev nkag siab, thiab tseem ua rau lawv muaj kev ruaj khov zoo dua. Txawm li cas los xij, siab crystallinity kuj tseem tuaj yeem ua rau muaj cov fiber ntau ntawm cov fiber ntau, thiab muaj kev sib tsoo yog qhov tshwm sim thaum raug rau kev cuam tshuam loj sab nraud.
Kev Qhia Txog: Thaum kev tsim khoom thiab kev tsim khoom, cov qauv siv roj av lossis cov qauv siv lead ua ntawm nylon staps fibers nyhav yuav tsum tau taw qhia rau hauv qee yam kev taw qhia. Qhov nce hauv kev cob qhia tuaj yeem txhim kho lub zog, modulus thiab lwm yam khoom ntawm cov fiber ntau hauv kev taw qhia kev taw qhia. Piv txwv li, hauv cov txheej txheem ntawm textile, cov txheej txheem tshwj xeeb tuaj yeem ua rau cov kab mob nylon staple fibers hauv cov ntaub ntau kev txiav txim siab, yog li kev txhim kho cov ntaub ntawv ntawm cov ntaub.
2. Morphological Cov Qauv:
Hla - ntu ntawm cov duab: tus ntoo khaub lig} ntu ntu ntawm cov nylon staple fibers feem ntau yog li niaj zaus lossis kwv yees li ncig. Cov duab no tso cai rau cov fiber kom tiv thaiv kev ntxhov siab ntau dua thaum muaj kev ntxhov siab hauv cheeb tsam lub zog thiab ruaj khov ntawm cov fiber.
Ntev lub ntsej muag: los ntawm lub ntsej muag ntev, cov saum npoo ntawm Nylon staple fibers yog qhov sib txhuam du, thiab kev sib txhuam ntawm cov fibers yog me me. Cov yam ntxwv no tso cai nylon staple fibers kom yooj yim rau kev sib txuas thiab npaj thaum kiv, tab tom ua haujlwm, txhim kho kev ua tau zoo; Nyob rau tib lub sijhawm, thaum sib xyaw nrog lwm cov fibers, lawv kuj tseem tuaj yeem ua tau zoo dua nrog lwm cov fibers kom muab tag nrho cov kev ua si rau lawv cov txiaj ntsig.
