Raw Material Preparation: Tshwj xeeb resin pellets-xws li nylon (PA) lossis polyester- raug xaiv los ua cov khoom siv hauv paus. High- cov khoom kawg siv cov khoom zoo nylon (xws li DuPont filaments), thaum cov bristles ua haujlwm tau ua ntej- sib xyaw nrog cov tshuaj tua kab mob lossis zaub mov- qib abrasive hais.
Melt Extrusion: Cov ntaub ntawv nyoos yog pub rau hauv ib qho tshwj xeeb extruder thiab rhuab mus rau 260-280℃kom ua tiav melting. Cov resin yog ces extruded los ntawm ib tug siab -precision spinneret nyob rau hauv ib tug ruaj khov siab ntawm 1550-1650 Pa, ua nruam, uniform monofilament bristles.
Thaum tshav kub kub Stretching thiab Teeb: Cov extruded filaments undergo ib tug multi-theem, kub-tswj tshav kub-stretching txheej txheem. Qhov no ua rau cov qauv fiber ntau molecular, ua kom muaj zog, ua haujlwm rau flattening, thiab elasticity, yog li ua kom cov bristles tsis yooj yim deform thaum siv ntev.
Dej Txias thiab Chaw Teeb: Cov filaments stretched dhau los ntawm qhov tsis tu ncua -kub dej txias da dej kom txias thiab teeb tsa, txo cov kev ntxhov siab sab hauv. Cov txheej txheem no tseem tshem tawm cov impurities saum npoo, ua kom lub ntsej muag du, huv si.
Winding thiab Organizing: Cov cua txias, teeb filaments raug mob zoo zoo nyob rau hauv kev tswj nruj nruj rau hauv cov coils kom zoo, tiv thaiv pob los yog tangles.
Tsau-Length Cutting: Raws li cov qauv txhuam hniav tsim tshwj xeeb, cov filaments tsis tu ncua raug txiav rau hauv bristle ntu ntawm qhov ntev ntev. Cov no yog tom qab ntawd ua tiav los ntawm combing cov cuab yeej rau hauv cov khoom zoo sib xws, cov qauv bristle bundles.
