Cov txheej txheem ntau lawm ntawm soluble fiber yog qhov nyuaj thiab cov txheej txheem sib txuas, uas yog cov txuas rau peb cov ntsiab lus tseem ceeb: polymerization, ua haujlwm tom qab.
Hauv cov theem polymerization, qhov no yog lub hauv paus rau kev tsim cov soluble fibers. Nws yog ib qho tsim nyog los ua tib zoo xaiv cov monomers thiab nruj me ntsis tswj cov tshuaj tiv thaiv kev mob, suav nrog kub, siab thiab catalyst ntau. Los ntawm kev tswj hwm cov ntsiab lus no, cov molecular hnyav thiab cov kev sib txuam ntawm cov polymer tuaj yeem tsim kho kom zoo dua qub ntawm cov soluble fibers nrog kev ua tau zoo.
Spinning thev naus laus zis, raws li cov tseem ceeb thev naus laus zis hauv kev tsim cov soluble fibers, suav nrog melt spinning, daws spinning thiab qhuav-dav dav ntub spinning. Melt spinning yog tsim nyog rau thermoplasuricity polymers xws li polylactic acid. Cov polymer yog thawj rhuab thiab melted, thiab tom qab ntawd extruded thiab txias los ntawm kev sib tw kom muaj cov fibers. Kev daws kev txiav txim yog haum rau soluble polymers xws li Polycaprolactone. Cov polymer yog yaj hauv cov kuab tshuaj, extruded los ntawm cov spinneret, thiab cov kev daws teeb meem evaporates los ua cov fibers. Qhuav-dav hlau ntub thev naus laus zis ua ke cov txiaj ntsig zoo ntawm meltages thiab cov tshuaj spinning thiab tuaj yeem siv rau ntau hom polymers.
Cov txheej txheem kev ua dua tshiab kuj tseem ceeb heev, thiab suav nrog kev ncab, tshav kub, ntxuav, kom qhuav thiab qhuav. Ncab tuaj yeem txhim kho cov cuab yeej siv thiab crystallinity ntawm cov fiber ntau, cov qauv cua sov tuaj yeem siv cov qauv fiber ntau, thiab kev ntxhua khaub ncaws kom tau siv los tshem tawm cov impurities thiab cov kuab tshuaj. Nrog kev nce qib ntawm thev naus laus zis, cov tshiab tom qab ua haujlwm xws li microwave cua sov thiab ultrasonic kev kho tau zoo, uas tau txhim kho cov nqi ntau lawm thiab txo cov nqi ntau lawm.
Tom qab cov txheej txheem nruj no ntws, cov soluble fibers thaum kawg ua tau tuaj yeem ncav cuag ib qho kev daws teeb meem zoo ib yam li ntawm 7.
