Aramid Staple Fiber ntau

Textile Processability Core Qhov zoo ntawm Aramid Staple Fiber

Nyob rau hauv sib piv rau nruam filaments, aramid staple fibers yog crimped, txiav -ntev aromatic polyamide fibers ua tshwj xeeb tshaj yog rau spinning thiab nonwoven manufacturing kab. Lawv ua hauj lwm tshwj xeeb zoo nrog cov txheej txheem textile machinery. Meta-aramid (PMIA) staple fibers (0.8–15 denier) thiab para-aramid (PPTA) staple fibers (1.5–4 denier) yog ob hom aramid staple fiber ntau uas peb muab. Txhawm rau lav tus nqi qis qis qis, ob qho tib si muaj kev tswj hwm saum npoo tiav thiab tsis sib xws crimp. Vim tias lawv qhov qis qis thiab qis qis qis, meta-aramid staple fibers tuaj yeem ua tau yooj yim ntawm cov pa looms yam tsis tas yuav tsum tau hloov kho cov cuab yeej tshwj xeeb. Lawv kuj tseem muaj qhov ntev -lub sij hawm thermal stability ntawm 204℃thiab inherent nplaim tsis kam (LOI Ntau dua los yog sib npaug rau 28), uas yog cov yam ntxwv tsim nyob rau hauv lub polymer saw.Rau knitting tiv thaiv hnab looj tes, para-aramid staple fibers muab zoo heev txiav tsis kam vim lawv ntau zog tenacity thiab modulus. Txhawm rau tiv thaiv cov dej khib nyiab thib ob los ntawm cov txheej txheem dyeing, ob qho tib si variations muaj nyob rau hauv undyed (dawb) thiab dope{19}}dyed versions.

Dual -System Staple Fiber Khoom Matrix & Downstream Matching

Peb cov khoom lag luam ntawm aramid staple fibers suav nrog ob qho tib si hnyav- tsis pom zoo qib kev lag luam thiab nplua- cov qib tsis zoo textile; para-aramid ntau yam muaj nyob rau hauv cov qauv txiav ntev ntawm 38mm, 51mm, thiab 76mm kom txaus siab rau ntau yam kev xav tau spinning. Vim tias nws muaj kev tiv thaiv rau acidic thiab alkaline corrosive gases thiab ua rau lub neej ntev kev pab cuam, meta-aramid staple fiber yog ib qho tseem ceeb raw khoom rau siab - kub flue gas filtering hnab siv nyob rau hauv steel mills thiab pov tseg incineration chaw. Tsis tas li ntawd, nws yog siv los ua cov kev lag luam uas tiv taus cua sov thiab ntxiv dag zog rau lub tsheb roj hmab hoses.Para-aramid staple fiber ntau yog tsim rau hauv cov xov paj rau kev lag luam siab- qhov kub thiab txias, nplaim taws- tiv thaiv textiles, thiab txiav- hnab looj tes tiv taus.

Txhua batch yog raug rau ntau nyob rau hauv -tsev kuaj lub zog tensile, crystallinity, thiab crimp uniformity ua ntej xa mus rau thoob ntiaj teb cov neeg siv khoom nyob rau hauv ntau tshaj 30 lub teb chaws; UL, CE, thiab OEKO-TEX cov ntaub ntawv pov thawj yog muab rau txhua qhov kev txiav txim.
