Yuav ua li cas thiaj paub seb cov ntaub yog ua los ntawm cov tshuaj fibers lossis ntuj fibers?
May 08, 2025
Kev txheeb xyuas seb cov ntaub yog ua los ntawm cov tshuaj fibers lossis cov fibers ntuj tuaj yeem ua tau los ntawm kev soj ntsuam nws cov tsos, hnov nws zoo nkauj, hlawv nws kom hnov tsw tsw, tshuaj xyuas hauv qab lub tshuab ntsuas, lossis siv txoj kev sib cais.
Txoj Kev Saib Xyuas
Natural Fibers: Feem ntau, lawv muaj lub ntsej muag zoo nkauj thiab muag muag, nrog cov ntaub ntawv tsis xwm yeem lossis xim txawv. Piv txwv li, paj rwb fibers feem ntau yog dawb los yog lub teeb daj nyob rau hauv cov xim, nrog ntuj twists ntawm qhov chaw; wool fibers muaj ntuj curls thiab tsis sib xws thickness; linen fibers yog coarser, nrog txawv longitudinal kab txaij.
Chemical Fibers: Lawv feem ntau muaj cov duab zoo sib xws thiab cov xim zoo ib yam, nrog rau qhov chaw du thiab txawm tias fiber ntau tuab. Piv txwv li, polyester thiab nylon fibers muaj qhov chaw du heev, siab gloss, thiab qee zaum yog yas-zoo li kev ntxhib los mos.
Kov txoj kev
Natural Fibers: Lawv zoo li mos thiab xis, nrog rau cov tawv nqaij zoo -kev phooj ywg. Cov paj rwb fibers yog mos thiab me ntsis elastic, muaj zog noo noo nqus, muab kev xav qhuav; wool fibers hnov sov, fluffy, thiab elastic heev, sai sai rebounding tom qab raug nyem; linen fibers xav tias me ntsis txhav thiab ntxhib tab sis muaj qhov tshwj xeeb txias.
Chemical Fibers: Lawv feem ntau zoo li tus kov. Qee cov tshuaj fibers, xws li polyester thiab nylon, xav tias tawv thiab muaj elasticity zoo tab sis tsis muaj softness thiab fluffiness ntawm ntuj fibers. Acrylic fibers yuav zoo li mos, tab sis piv rau cov ntaub plaub, lawv elasticity thiab fluffiness yog txawv, thiab lawv cov warmth tuav yog qis dua.
Txoj kev hlawv
Natural Fibers: Cov ntxhiab tsw thiab qhov seem ntawm qhov kub hnyiab txawv ntawm cov tshuaj fiber ntau. Paj rwb hlawv nrog nplaim daj, emitting ib daim ntawv - zoo li tsw, tawm hauv qab mos, grey tshauv; wool burns nrog ib tug me me nplaim, ua ib tug burnt feather tsw, thiab cov ntaub ntawv dub, brittle hlaws; linen burns nrog ib tug daj nplaim, emitting ib quav nyab - zoo li tsw, thiab nplooj greyish - dawb tshauv.
Chemical Fibers: Cov yam ntxwv kub kub sib txawv. Polyester kub hnyiab nrog cov xim daj - nplaim taws dawb, cov pa luam yeeb dub, thiab cov ntxhiab tsw ntxhiab tsw, tawm hauv qab dub, tawv tawv; nylon kub hnyiab nrog cov nplaim xiav, cov pa luam yeeb dawb, thiab cov celery - zoo li tsw, tsim cov pob dawb lossis lub teeb xim av; acrylic kub hnyiab nrog cov nplaim dawb, cov pa luam yeeb dub, thiab tsw ntxhiab tsw, tawm hauv cov hlaws dub, tawv tawv.
Txoj kev Microscope
Natural Fibers: Nyob rau hauv lub tshuab tsom iav, lawv pom cov yam ntxwv morphological tshwj xeeb. Paj rwb fibers muaj lub raum -zoo li tus ntoo khaub lig-section nrog lub hauv paus kab noj hniav thiab ntuj twists longitudinally; wool fibers muaj nplai rau ntawm qhov chaw thiab ib puag ncig lossis oval cross-section; linen fibers muaj polygonal cross-section nrog rau hauv nruab nrab kab noj hniav thiab longitudinal nodes thiab kab txaij.
Chemical Fibers: Lawv morphology nyob rau hauv lub tshuab tsom iav yog zoo ib yam. Piv txwv li, polyester fibers muaj ib tug puag ncig cross-section thiab ib tug du longitudinal nto; nylon fibers kuj muaj ib puag ncig tus ntoo khaub lig-section thiab du nto; acrylic fibers muaj dumbbell-zoo li tus los yog round cross-section nrog longitudinal grooves.
Txoj Kev Txiav Txim Siab
Natural Fibers: Cov fibers ntuj sib txawv yaj sib txawv hauv ntau cov kuab tshuaj. Piv txwv li, paj rwb fibers tsis yaj nyob rau hauv cov organic solvents nyob rau hauv chav tsev kub tab sis yaj nyob rau hauv concentrated sulfuric acid; wool fibers maj mam yaj hauv alkaline daws.
Tshuaj Fibers: Lawv solubility kuj txawv. Polyester fibers tsis yaj nyob rau hauv cov organic solvents los yog dilute acids thiab bases tab sis yaj nyob rau hauv tej kuab tshuaj xws li ib tug sib tov ntawm phenol thiab tetrachloroethane; nylon fibers yaj nyob rau hauv formic acid los yog concentrated sulfuric acid. Kev soj ntsuam li cas fibers yaj hauv cov kuab tshuaj sib txawv tuaj yeem pab txheeb xyuas lawv hom.
