Cov fiber ntau no tuaj yeem ntxuav thiab dyed
Ib pab neeg ntawm Suav cov kws tshawb fawb tau tsim cov xov paj fiber ntau nrog cov thermal rwb thaiv tsev tshwj xeeb tshwm sim los ntawm polar bear fur, Xinhua qhia. Raws li kev tshawb fawb luam tawm nyob rau hauv phau ntawv Journal Science, qhov no encapsulated airgel fiber yog ntxuav, dyeable, ruaj thiab siv tau nyob rau hauv niaj hnub textiles.
Airgel fibers feem ntau tsis muaj zog thiab ncab yuav tsum tau woven rau hauv fabrics thiab poob lawv insulating zog nyob rau hauv ntub dej los yog ntub dej. Txawm li cas los xij, cov kws tshawb fawb ntawm Zhejiang University tau txais kev tshoov siab los ntawm cov kab mob polar bears 'cov plaub hau tshwj xeeb, uas ua rau lawv sov thiab qhuav. Raws li txoj kev tshawb no, cov plaub hau plaub hau muaj ib tug ntxeem tau core enclosed nyob rau hauv lub ntom qauv ntawm sheath.
Los ntawm kev ua raws li cov qauv ntawm cov tub ntxhais thiab sheath ntawm dais cov plaub hau, cov kws tshawb fawb tau tsim ib qho tawv airgel fiber ntau nrog lamellar pores uas muaj txiaj ntsig zoo cuam tshuam cov hluav taws xob hluav taws xob nyob ze ntawm daim tawv nqaij thiab khaws nws lub zog txhua yam, ua rau nws tsim nyog rau knitting lossis weaving.
Raws li txoj kev tshawb fawb, cov fiber ntau khaws nws cov thermal rwb thaiv tsev cov khoom nrog kev hloov me me txawm tias tom qab 10,000 rov ua dua cov voj voog ntawm 100 feem pua. Pab neeg tshawb fawb tau sim cov fiber ntau hauv lub tsho nyias nyias, uas, txawm hais tias yog li ib feem tsib ntawm cov tuab ntawm lub tsho hauv qab, muaj cov thermal rwb thaiv tsev zoo piv rau cov tsho tuab.
Raws li cov kws tshawb fawb, qhov kev tsim khaub ncaws "thinned" no muab txoj hauv kev zoo rau kev txhim kho cov khoom siv ntau yam airgel fibers thiab textiles yav tom ntej.
