Jute Felt Needle-punching Production Line
Process Flow
Jute bag → Unpacking machine → Coarse loosening (enhanced, breaking up the knots) → Multi-bin blending machine (Jute + PET mixed in proportion) → Fine loosening → Air pressure cotton box → Reinforced double-lap combing machine → Cross laying machine → Pre-needling → Main needling (heavy-duty needling machine) → (Optional heat setting / polishing) → Online weight detection → Edge cutting → Storage → Rolling up
Key Points: The yellow Jute dust is large and there are many Jute knots. A full set of high-power dust removal systems are provided along the entire line; the combing needle fabric should be selected as wear-resistant hard needle fabric to prevent rapid wear.
Equipment List for the Entire Set
- Opening and Mixing Unit (Special for Yellow Jute)
Heavy-duty opening and unloading (increased roller diameter, dispersing Jute knots and hard masses); multi-bin cotton mixer; equipped with dust removal box for impurities; High-power Central Dust Removal System (large amount of Jute dust, explosion-proof requirements)
- Feeding + Combing Unit
Pressure cotton box for quantitative feeding; Double Lint Liners and Double Teeth Combing Machine, upgraded needle fabric for wear resistance; pure yellow Jute cannot be combed, must mix with PET to improve web formation
- Cross-laying Machine
Thick felt with multiple layers of stacked nets, controlling uniformity of thickness; common thickness of horticultural / sound insulation yellow Jute felt is generally larger
- Needle-impregnating Unit
Pre-impregnation + 1-2 heavy-duty main needle impregnation machines; select coarse needles, reinforced needle plates; yellow Jute fibers are hard, prone to break needles, the planting density cannot be too high
- Optional Configurations at the Later Stage
Hot setting oven (used when blending Bico fibers, to enhance felt strength); polishing roller (surface flatness)
- Online weight detection, cutting, storage, automatic winding, PLC linkage control
