Ngaba uyazazi iintsinga zekhemikhali ezinkulu ezintandathu? (Ipolypropylene, iNayiloni, iAkriliki)

Ngaba uyazazi iintsinga zekhemikhali ezinkulu ezintandathu? I-polyester, i-acrylic, inayiloni, i-polypropylene, i-vinylon, i-spandex. Nantsi intshayelelo emfutshane yeempawu zabo.

Ifiber yePolyester yaziwa ngokomelela kwayo okuphezulu, ukumelana nempembelelo entle, ukuxhathisa ubushushu, ukuxhathisa umhlwa, ukuxhathisa inundu, iasidi kunye nokuxhathisa kwealkali. Kananjalo inokukhanya okuhle kakhulu, okwesibini kuphela kwi-acrylics. Emva kweeyure eziyi-1000 zokuvezwa, iifiber zepolyester zigcina i-60-70% yokuqina kwazo okuqinileyo. Ayina hygroscopicity embi kwaye kunzima ukuyidaya, kodwa ilaphu kulula ukulihlamba kwaye lome ngokukhawuleza kwaye linobume obulungileyo. Oku kuyenza ilungele “ukuhlamba nokunxiba” iilaphu. Ukusetyenziswa kwefilament kubandakanya imisonto eneelastiki ephantsi yelaphu ezahlukeneyo, ngelixa iintsinga ezimfutshane zinokudityaniswa nomqhaphu, uboya, ilinen, njl. Kwimizi-mveliso, ipolyester isetyenziswa kwintambo yamatayara, iminatha yokuloba, iintambo, ilaphu lokuhluza kunye nokugquma.

Inayiloni, kwelinye icala, ixabiswa ngokomelela kwayo kunye nokuxhathisa kwe-abrasion, iyenza ibe yeyona fiber ilungileyo kwezo zakhiwo. Ubuninzi bayo buphantsi, ilaphu lilula ngobunzima, linokuqina okulungileyo kunye nokuchasana nomonakalo wokukhathala. Kananjalo inozinzo oluhle lweekhemikhali kunye nokumelana ne-alkali, kodwa hayi ukumelana ne-asidi. Nangona kunjalo, ukuxhathisa kwayo ekukhanyeni kwelanga kubi, kwaye ukubonakaliswa kwexesha elide kuya kubangela ukuba ilaphu lijike lijike kwaye linciphise amandla alo. Ngelixa i-hygroscopicity ingeyosuti yayo eyomeleleyo, isagqithisa i-acrylic kunye nepolyester kulo mba. Inayiloni isoloko isetyenziswa njengefilament kumashishini okunitha kunye nesilika, kwaye ifayibha emfutshane isoloko idityaniswa noboya okanye uhlobo lwemichiza yodidi lwemichiza yeentsinga zegabardine, ivanillin, njalo njalo. Inayiloni isetyenziswa kwimizi-mveliso ukwenza iintambo, iminatha yokuloba, iikhaphethi, iintambo, isihambisi. amabhanti kunye nezikrini.

I-Acrylic idla ngokubizwa ngokuthi "uboya bokwenziwa" kuba iimpawu zayo zifana kakhulu noboya. Ino-elastiki elungileyo ye-thermal kunye noxinzelelo oluphantsi, incinci kunoboya, inika ilaphu ubushushu obugqwesileyo. I-Acrylic nayo inokukhanya kwelanga okuhle kakhulu kunye nokuchasana kwemozulu, ukubeka kuqala kulo mba. Nangona kunjalo, ine-hygroscopicity embi kwaye kunzima ukuyidaya.
