1. Lub longitudinal nto ntawm daim ntawv polypropylene yog ncaj thiab du, thiab tus ntoo khaub lig seem yog puag ncig.
2. Ceev Qhov zoo tshaj plaws ntawm polypropylene fiber yog nws lub teeb zoo nkauj. Nws qhov ceev tsuas yog 0.91g / cm3, uas yog qhov sib txawv ntawm cov tshuaj fibers zoo tib yam. Yog li ntawd, polypropylene fibers ntawm tib qhov hnyav tuaj yeem tau txais thaj tsam siab dua li lwm cov fibers.
3. Lub zog thiab elongation Polypropylene muaj lub zog siab, siab elongation, siab pib modulus thiab zoo heev elasticity. Yog li ntawd, polypropylene fiber ntau muaj qhov 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.
4. Hygroscopicity thiab dyeability: lub teeb yuag, zoo warmth tuav; yuav luag tsis muaj noo noo nqus, tab sis muaj zog lub plawv nqus peev xwm, noo noo nqus thiab nqus dej yog pom tseeb; polypropylene fiber ntau muaj qhov nqus noo noo tsawg, yuav luag tsis muaj noo noo nqus, noo noo rov qab nyob rau hauv cov huab cua huab cua Zero. Tab sis nws muaj cov nyhuv wicking thiab tuaj yeem xa cov dej vapor los ntawm capillary hauv cov ntaub, tab sis nws tsis muaj qhov nqus dej. Polypropylene fiber ntau muaj cov dyeability tsis zoo thiab cov chromatograms tsis tiav, tab sis cov xim ntawm cov tshuaj qub tuaj yeem siv los ua qhov tsis txaus.
5. Acid thiab alkali resistant polypropylene fiber muaj tshuaj lom neeg zoo. Ntxiv nrog rau kev tiv taus cov concentrated nitric acid thiab concentrated caustic soda, polypropylene fiber kuj muaj cov kua qaub thiab alkali tsis kam, yog li nws tsim nyog siv los ua cov ntaub ntawv lim thiab ntim khoom.
6. Polypropylene fiber ntau, xws li lub teeb tsis kam, muaj lub teeb tsis zoo, tsis zoo thermal stability, yooj yim aging, thiab tsis resistant rau ironing. Tab sis ntxiv cov tshuaj tiv thaiv kev laus thaum lub sij hawm spinning tuaj yeem txhim kho nws cov kev tiv thaiv kev laus. Tsis tas li ntawd, polypropylene fiber ntau muaj cov hluav taws xob zoo, tab sis nws yooj yim los tsim hluav taws xob zoo li qub thaum ua. Vim yog cov thermal conductivity tsawg ntawm polypropylene, nws muaj kev sov siab zoo.
7. Lub zog ntawm high-strength polypropylene stretch yarn yog thib ob tsuas yog nylon, tab sis tus nqi tsuas yog 1/3 ntawm nylon; cov ntaub ua los ntawm nws muaj qhov ntev ruaj khov, zoo abrasion tsis kam thiab zoo tshuaj stability. Txawm li cas los xij, nws cov thermal stability tsis zoo, nws tsis tiv taus tshav ntuj, nws yooj yim rau hnub nyoog thiab nkig puas. Vim li no, cov tshuaj tiv thaiv kev laus feem ntau yog ntxiv rau polypropylene.
