Cov ntaub so tes muaj kev phom sij ntau dua rau kev kis kab mob microbial dua li cov khoom siv tu tus kheej ib txwm muaj thiab yog li ntawd xav tau cov tshuaj ntaucov tshuaj preservativesTxawm li cas los xij, nrog rau cov neeg siv khoom nrhiav kev ua kom cov khoom mos mos, cov tshuaj preservatives ib txwm muaj xws liMIT&CMIT, formaldehyde tso tawm tas mus li, paraben, thiab txawm tiasphenoxyethanoltau raug tiv thaiv rau ntau qib, tshwj xeeb tshaj yog nyob rau hauv kev lag luam menyuam yaus so. Tsis tas li ntawd, nyob rau hauv xyoo tas los no, vim yog qhov tseem ceeb rau kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov, ntau thiab ntau lub npe tau tig mus rau ntau cov ntaub ntuj. Cov kev hloov pauv no txhua yam ua rau muaj kev cov nyom ntau dua rau kev khaws cia cov ntaub so ntub. Cov ntaub so ntub ib txwm muaj cov ntaub tsis-woven muaj polyester thiab viscose, uas cuam tshuam kev tiv thaiv xeb. Viscose fiber yog hydrophilic ntau dua, thaum polyester fiber yog lipophilic ntau dua. Ntxiv rauDMDM H, feem ntau ntawm cov tshuaj preservatives siv feem ntau yog lipophilic ntau dua thiab yooj yim adsorbed los ntawm polyester fibers, ua rau tsis txaus concentration ntawm preservative tiv thaiv rau viscose fibers thiab dej theem qhov chaw, nce viscose fibers thiab dej. Lub theem dej yog qhov nyuaj rau tiv thaiv xeb, uas ua rau muaj qhov nyuaj ntawm kev tiv thaiv xeb ntawm cov ntaub so ntub. Feem ntau, viscose fiber thiab lwm yam ntaub so ntub ntuj yog qhov nyuaj dua los tiv thaiv xeb dua li cov ntaub so ntub tshuaj fiber.
