Combustion Properties ntawm Webbing

Txhawm rau txheeb xyuas cov ntaub ntawv raw ntawm warp thiab weft yarns nyob rau hauv ib qho piv txwv ntawm webbing ntawm tsis paub muaj pes tsawg leeg, rho tawm ob peb strands ntawm txhua tus thiab hlawv lawv tus kheej nrog ib tug sib zog. Saib xyuas lub cev tshwm sim thaum lub sij hawm combustion-tshwj xeeb yog cov yam ntxwv ntawm cov nplaim taws, kev coj tus cwj pwm yaj, tsw tawm, thiab lub xeev ntawm cov tshauv - los txiav txim seb hom fiber ntau.

Cotton Fibers vs. Linen (Hemp) Fibers
Ob lub paj rwb thiab linen fibers ignite tam sim ntawd thaum sib cuag nrog nplaim taws thiab hlawv sai sai nrog cov nplaim daj thiab cov pa luam yeeb xiav. Lawv txawv ntawm cov ntxhiab tsw tawm thiab cov tshauv tsim: paj rwb tsw zoo li cov ntawv hlawv, thaum linen tsw zoo li ntoo tshauv. Tom qab hlawv, paj rwb tawm me me ntawm cov xim dub lossis grey hmoov tshauv, whereas linen tsim tawm me me ntawm - cov hmoov tshauv dawb.

Nylon vs Polyester
Nylon (polyamide fiber) sai sai curls thiab yaj mus rau hauv ib qho dawb, gelatinous tshuaj thaum nyob ze ntawm cov nplaim taws. Nws melts, drips, thiab npuas thaum hlawv tab sis tsis muaj nplaim taws nws tus kheej; nws tawm tsam mus txuas ntxiv hlawv ib zaug tshem tawm ntawm qhov hluav taws kub. Nws eits ib tug celery -zoo li tsw, thiab lub teeb tshwm sim - xim av yaj residue yog ib qho nyuaj rau crush tom qab txias.
Polyester (polyester fiber) ignites yooj yim thiab shrinks / melts thaum nyob ze ntawm cov nplaim taws. Nws hlawv nrog cov nplaim daj, tawm cov pa luam yeeb dub thaum yaj, thiab muab cov ntxhiab tsw qab. Cov hmoov tshauv tsim ib qho nyuaj, tsaus nti - cov pob liab liab uas tuaj yeem sib tsoo ntawm cov ntiv tes.

Acrylic thiab Polypropylene (PP)
Acrylic (polyacrylonitrile fiber) softens thiab shrinks thaum nyob ze ntawm cov nplaim taws. Thaum hluav taws kub, nws tawm cov pa taws dub thiab nplaim taws dawb; nws tseem kub hnyiab tau sai tom qab tshem tawm ntawm cov nplaim hluav taws, tso cov pungent, acrid tsw reminiscent ntawm hlawv nqaij. Cov residue muaj xws li tsis xwm yeem, tawv dub pob uas crumble yooj yim thaum crushed los ntawm tes.

Vinylon thiab Chlorofiber
Vinylon (polyvinyl cawv-formaldehyde fiber) nyuaj rau ignite; nws melts thiab shrinks nyob ze ntawm cov nplaim taws. Thaum lub sij hawm combustion, ib tug me me nplaim tshwm nyob rau hauv lub ntsis, loj hlob raws li cov fiber melts mus rau hauv lub gelatinous xeev; nws emits cov pa luam yeeb dub thiab iab, tsw ntxhiab tsw. Cov residue tsim me me, dub, hlaws -zoo li cov khoom uas tuaj yeem tsoo nrog cov ntiv tes.

Spandex thiab Fluorofiber
Spandex (polyurethane fiber) melts thiab hlawv ib txhij thaum nyob ze ntawm cov nplaim taws, ua rau lub teeb xiav; nws tseem yaj thiab hlawv tom qab tshem tawm ntawm qhov chaw, emitting ib tug txawv, pungent tsw. Cov residue yog mos, fluffy dub tshauv. Fluorofiber (polytetrafluoroethylene fiber)- hu ua "fluorite fiber" los ntawm ISO- tsuas yog yaj ze ntawm nplaim taws; Nws yog ib qho nyuaj rau ignite thiab tsis txhawb combustion. Ntawm cov npoo, nplaim taws tshwm xiav -ntsuab raws li cov khoom carbonizes thiab decomposes; Nws tso tawm cov pa roj carbon monoxide, thiab cov yaj tuaj yeem ua kom tawv tawv, puag ncig cov hlaws dub. Hauv kev lag luam textile, fluorofiber feem ntau yog siv los tsim cov xov zoo -kev ua haujlwm xaws xov.
