High-speed Chenille Machine Floating Fiber Defect Causes and Elimination Methods

Excessive floating fiber is a common appearance defect of Chenille yarn, which affects fabric cleanliness and wear resistance, and can be effectively eliminated through equipment precision adjustment and process optimization.
Blade passivation and uneven gap are the primary causes of floating fiber, contributing 66% of fluffy and messy yarn appearance defects in Chenille production.
Qualified blade clearance must be controlled within 0.15 mm; excessive gap will lead to incomplete fiber cutting and produce a large number of disordered floating fibers.
Unstable spindle speed fluctuation over ±5 rpm causes uneven fiber feeding, increasing floating fiber rate by 4.8% in batch production.
Workshop dry environment below 58% RH enhances static adsorption, making floating fibers adhere to yarn surface and difficult to remove.
Lanxiang Machinery high-speed Chenille machine adopts precision integrated blade group, reducing floating fiber generation rate by 50% compared with ordinary equipment.
Timely blade grinding and replacement every 600 working hours ensures cutting sharpness and maintains clean yarn appearance.
Reasonable tension matching avoids excessive fiber pulling damage, effectively reducing broken fine fiber residues on yarn surface.
After full optimization, the finished Chenille yarn floating fiber rate can be controlled below 0.8%, meeting high-end decoration textile standards.
### FAQ
