Cov ntaub ntawv raw ntawm cov hnab woven feem ntau yog ntau yam khoom siv yas xws li polyethylene thiab polypropylene. Cov hnab yas woven yog ua los ntawm polypropylene resin ua cov khoom tseem ceeb, uas yog extruded thiab stretched rau hauv cov xov hlau, thiab ces weaved thiab ua rau hauv hnab.
Kev tsim cov hnab woven feem ntau yog polypropylene. Polypropylene yog ib qho thermoplastic cob tau los ntawm polymerization ntawm propylene.
1. Muaj zog elongation: Polypropylene muaj lub zog siab, loj elongation, siab pib modulus thiab zoo heev elasticity. Yog li ntawd, polypropylene fiber ntau muaj zoo abrasion tsis kam. Tsis tas li ntawd, lub zog ntub dej ntawm polypropylene yog qhov sib npaug ntawm lub zog qhuav, yog li nws yog ib qho khoom siv zoo tshaj plaws rau kev ua nuv ntses nets thiab cables.
2. Hygroscopicity thiab dyeability: lub teeb yuag, zoo thaum tshav kub kub tuav, yuav luag tsis muaj noo noo nqus, tab sis muaj zog wicking muaj peev xwm, pom tseeb noo noo nqus thiab perspiration nyhuv; polypropylene fiber ntau muaj hygroscopicity tsawg heev, yuav luag tsis muaj noo noo nqus, thiab cov dej noo rov qab nyob rau hauv cov huab cua huab cua nyob ze ze ntawm xoom. Tab sis nws muaj cov nyhuv wicking, uas thauj cov dej vapor los ntawm capillaries hauv cov ntaub, tab sis tsis ua ib qho kev nqus dej nws tus kheej. Polypropylene muaj dyeability tsis zoo thiab tsis tiav chromatogram, tab sis woven hnab whitening tus neeg sawv cev yuav siv tau. Kev nqus dej noo, cov dej noo rov qab nyob rau hauv cov huab cua huab cua yog ze rau xoom. Tab sis nws muaj cov nyhuv wicking, uas thauj cov dej vapor los ntawm capillaries hauv cov ntaub, tab sis tsis ua ib qho kev nqus dej nws tus kheej. Polypropylene tsis zoo dyeability thiab tsis tiav xim spectrum, tab sis woven hnab brightener siv tau.
Nws feem ntau nug tias hauv kev tsim cov hnab yas dawb, kom ua tiav cov nyhuv whitening, nws puas zoo dua los siv tus neeg sawv cev dawb lossis titanium dioxide? Titanium dioxide yog tus neeg saib xyuas lub cev, uas yog los npog thiab ua kom dawb huv, thiab ntxiv ntau dhau yuav cuam tshuam rau tus nqi tensile ntawm cov khoom, thaum fluorescent whitening tus neeg saib xyuas yog kho qhov muag, uas ntxiv txhim kho tus nqi whiteness ntawm cov khoom los ntawm kev kho qhov muag. Feem ntau, qhov ntau npaum li cas me me, tsuas yog yuav tsum tau ntxiv 200-300 grams fluorescent whitening tus neeg sawv cev rau ib tuj ntawm cov yas, cov hnab yas woven tau pom zoo kom siv OB-1 tshwj xeeb brightener rau woven hnab, cov nyhuv whitening. yog pom tseeb!
