Cov txhuam txhuam txhuam hauv cov bristles uas siv dav tshaj plaws yuav tsum yog cov nylon txhuam hlau, nylon txhuam hlau yog lub ntsiab ntawm polyamide feem ntau hu ua nylon (Nylon), lus Askiv lub npe Polyamide (PA luv), yog lub ntsiab molecular saw muaj ib qho rov ua dua ntawm cov pab pawg amide - [NHCO]- cov khoom siv thermoplastic, suav nrog aliphatic PA, aliphatic-aromatic PA thiab aromatic PA.Xws li aliphatic PA, aliphatic-aromatic PA thiab aromatic PA, ntawm uas, aliphatic PA ntau yam, ntau lawm, dav siv, thiab nws lub npe los ntawm tus naj npawb ntawm carbon atoms nyob rau hauv lub synthesis ntawm cov monomer tshwj xeeb.

Nylon nyob rau hauv lub ntsiab ntau yam ntawm nylon 6 thiab nylon 66, accounting rau lub meej dominance ntawm nylon kev hloov kho ntawm ib tug loj tus naj npawb ntawm ntau yam, xws li reinforced nylon, monomer casting nylon (MC nylon), tshuaj tiv thaiv txhaj tshuaj molding (RIM) nylon, aromatic nylon , pob tshab nylon, siab-tshuaj (super-tough) nylon, electroplating nylon, conductive nylon, nplaim-retardant nylon, nylon thiab lwm yam polymers thiab alloys kom tau raws li qhov sib txawv tshwj xeeb yuav tsum tau, lug siv raws li hlau, ntoo, ntoo, thiab lwm yam ntaub ntawv. , thiab dav siv nyob rau hauv zus tau tej cov nylon.Peb tau dav siv los hloov cov khoom siv ib txwm muaj xws li hlau thiab ntoo, thiab ua ntau yam khoom siv.
