Production line and factory setup overview
A small/medium monofilament line producing one PET or PP broom-bristle family through polymer drying and blending, melt extrusion and fine filtration, spinneret forming, water quench, multi-stage hot drawing, heat setting and relaxation, optional crimping or flagging, oil finish, tension-controlled winding or bundle cutting, diameter and tensile inspection and packing.
Recommended lowest-entry line configuration Launch one straight or lightly crimped household-broom filament in one polymer and diameter at 80-150 kg/day. Include dryer, single-screw extruder, filter/spinneret, quench, draw rollers and hot tanks/ovens, annealing, finish applicator, winding/cutting and bristle laboratory. Do not claim paintbrush, toothbrush or cosmetic filament from a broom-grade line without separate precision trials.
Production process and implementation sequence
- Polymer release and drying
- Extrusion and melt filtration
- Spinneret forming and quench
- Multi-stage hot drawing
- Heat setting and relaxation
- Optional crimping or flagging
- Winding or bundle cutting
- Diameter, tensile and recovery tests
Products, capacity and market fit
- Broom and brush workshops need consistent local bristle bundles.
- One polymer and diameter simplify draw and heat-setting recipes.
- Qualified PET bottle flake may be used only after washing, drying and colour control.
- Diameter, straightness, recovery and bundle consistency affect broom quality.
- Household-broom monofilament - Polymer, diameter, profile, colour, straight/crimped form, cut length, stiffness, tensile and bend recovery - Local broom and cleaning-brush assemblers
