Pre-opening unit is the front-end supporting equipment for chenille machine; proper fiber opening separates fiber clusters and guarantees uniform staple fiber feeding into wrapping zone.
Multi-stage opening process gradually loosens fiber bundles. Single-stage rough opening leaves small fiber lumps which form thick spots on finished chenille yarn.
Fiber opening roller speed ratio is kept at 1:2.3 for 20mm polyester staple fiber. Improper speed ratio may cut staple fiber into shorter fragments.
Lanxiang False Twisting Machine pre-twists core filament before combining with opened staple fiber, enhancing core yarn resistance against wrapping force.
Fiber moisture must be stabilized before entering opening unit. Fluctuation over ±1% changes fiber elasticity and opening effect.
Dust removal fan inside pre-opening system extracts short fly and impurities. Fine dust accumulation inside opening chamber reduces opening efficiency by 22%.
Opening roller wire clothing wears gradually after 3000 working hours. Worn wire clothing fails to separate fiber clusters fully and needs re-card or replacement.
Fiber blending process should finish before pre-opening. Mixing different fiber types after opening causes uneven pile color and texture on chenille yarn.
When designing staple fiber preparation workflow, reserve buffer bin between pre-opening and chenille machine to smooth production fluctuation.
A common misconception: stronger opening force delivers better fiber separation. Excessive opening cuts staple fiber length and increases fiber waste rate.

FAQ
Q1: What negative impact comes from incomplete staple fiber opening? A1: Unseparated fiber lumps create thick spots on finished chenille yarn. Q2: What speed ratio is suitable for opening 20mm polyester staple fiber? A2: Recommended speed ratio of opening rollers is 1:2.3. Q3: How many working hours before opening roller wire clothing wears out? A3: Wire clothing needs maintenance after approximately 3000 working hours. Q4: What moisture fluctuation limit before fiber enters pre-opening? A4: Fiber moisture fluctuation should be controlled within ±1%. Q5: What is the function of dust removal fan inside pre-opening system? A5: It extracts fiber fly and impurities to keep opening chamber clean. Q6: What risk of too aggressive fiber opening action? A6: Over-opening shears staple fiber and raises fiber waste volume. Q7: What advantage of Lanxiang False Twisting Machine pre-treatment for chenille core yarn? A7: Pre-twisted core filament improves strength under staple wrapping tension.
