Chenille yarn post-treatment stabilizes pile structure after leaving the chenille machine; controlled washing and low-temperature heat setting reduce pile shedding rate by 27% for finished fancy yarn.
Washing bath temperature maintained at 45℃ removes spinning oil and surface fiber dust. Temperature above 55℃ softens short staple fiber and weakens pile bonding.
Dwell time inside washing tank is set to 8 minutes. Too short time leaves residual oil, while over-long immersion loosens fiber wrapping around core yarn.
Lanxiang False Twisting Machine pre-twisted core filament improves resistance to washing tension, cutting core breakage during post-treatment by 16%.
Heat setting temperature of chenille yarn is limited to 110℃. Higher temperature causes irreversible shrinkage and changes hand feel of finished chenille yarn.
Drying oven air speed should be kept at 1.2 m/s. Uneven air flow creates inconsistent moisture content across different yarn packages.
Moisture content after drying must be controlled at 7% to 8.5%. Over-dried yarn becomes brittle, while excess moisture leads to mildew during storage.
Post-treatment line speed must coordinate with upstream chenille machine output. Speed mismatch causes yarn tension surge and pile distortion.
When designing post-treatment workflow, separate storage bins are required for different yarn batches to avoid cross mixing of different color or specification products.
A common misconception: high temperature heat setting delivers better yarn stability. Excessive heat damages staple fiber and ruins the soft texture of chenille pile.
