Raws li kev sib txawv ntawm cov tshuaj muaj pes tsawg leeg thiab cov yam ntxwv ntawm kev sib xyaw ntawm cov khoom siv tsis-woven, cov fibers tsis-woven tuaj yeem raug faib ua roughly cais. Kev sib piv ntawm combustion yam ntxwv ntawm ntau hom non-woven fibers yog raws li nram no:
(1) paj rwb, hemp, viscose fiber, tooj liab ammonia fiber: ze rau cov nplaim taws: tsis shrinking thiab tsis melting; Tiv tauj nrog nplaim taws: combustion ceev; Tawm ntawm nplaim taws: txuas ntxiv hlawv; tsw: tsw ntawm cov ntawv hlawv; Cov yam ntxwv seem: me me ntawm grey dub lossis grey dawb tshauv.
(2) silk thiab wool fiber: ze rau nplaim taws: curl thiab yaj; Tiv tauj nplaim: curl, yaj thiab hlawv; Tawm ntawm nplaim taws: hlawv maj mam thiab qee zaum tua nws tus kheej; tsw: tsw ntawm cov plaub hau hlawv; Cov yam ntxwv ntawm residue: xoob thiab nkig dub hais los yog coke.
(3) polyester fiber: ze rau nplaim hluav taws: melting thiab shrinking; Tiv tauj nplaim hluav taws: melting, haus luam yeeb, qeeb combustion; Tawm ntawm nplaim taws: txuas ntxiv hlawv, qee zaum tua nws tus kheej; tsw: tshwj xeeb aromatic qab zib; Residue yam ntxwv: tawv dub puag ncig hlaws.
(4) nylon fiber ntau: ze rau nplaim taws: melting thiab shrinking; Tiv tauj nplaim: melting thiab haus luam yeeb; Tawm ntawm nplaim taws: nws tus kheej tua; Cov ntxhiab tsw: amino tsw; Residue yam ntxwv: nyuaj lub teeb xim av pob tshab puag ncig hlaws.
(5) acrylic fiber: ze rau nplaim taws: melting thiab shrinking; Tiv tauj nplaim: melting thiab haus luam yeeb; Tawm ntawm nplaim taws: txuas ntxiv hlawv, tawm cov pa taws dub; tsw: ntsim; Cov yam ntxwv ntawm residue: Cov hlaws dub tsis zoo, tsis yooj yim.
(6) Polypropylene fiber ntau: ze rau nplaim taws: melting thiab shrinking; Tiv tauj nplaim: melting thiab hlawv; Tawm ntawm nplaim taws: txuas ntxiv hlawv; tsw: paraffin tsw; Cov yam ntxwv seem: grey dawb tawv pob tshab puag ncig hlaws.
(7) spandex fiber ntau: ze rau nplaim taws: melting thiab shrinking; Tiv tauj nplaim: melting thiab hlawv; Tawm ntawm nplaim taws: nws tus kheej tua; tsw: tshwj xeeb tsw; Cov yam ntxwv ntawm residue: dawb colloidal.
(8). nylon fiber ntau: ze rau nplaim taws: melting thiab shrinking; Tiv tauj nplaim: melting, hlawv, emission dub pa luam yeeb; Tawm ntawm nplaim taws: nws tus kheej tua; tsw: pungent tsw; Residue yam ntxwv: tsaus xim av tawv thaiv.
(9) vinylon fiber ntau: ze rau nplaim taws: melting thiab shrinking; Tiv tauj nplaim: melting thiab hlawv; Tawm ntawm nplaim taws: txuas ntxiv hlawv, tawm cov pa taws dub; Cov ntxhiab tsw: tshwj xeeb ntxhiab; Residue yam ntxwv: irregular Brown tawv pob.
