SORONA BCF yarn features distinctive molecular structure and different thermal‑sensitivity compared with polypropylene and nylon BCF yarn. Many carpet factories adopt conventional storage and handling routines for chemical‑fiber yarn. Improper management damages bulkiness of yarn and leads to uneven pile surface and fuzz after tufting, impairing final carpet quality.
Warehouses for SORONA BCF yarn shall be dry and well‑ventilated, kept away from heat sources and heating facilities to avoid long‑term high‑temperature stacking. Although SORONA fiber shows decent heat resistance, persistent high temperature modifies internal crimp structure and reduces bulkiness. Pile fullness of finished carpets will decline even if no obvious defect can be observed on yarn appearance. Do not stack bobbins under heavy compression. Squeeze causes yarn‑layer adhesion and deformation and brings tangled yarn during tufting unwinding. Keep outer packages intact and block direct UV radiation to slow fiber aging.
Dropping and heavy impact are forbidden during handling and transportation. Internal crimp structure of bulking‑processed SORONA BCF yarn is vulnerable under violent external force and generates invisible damage, which turns into fuzz and breakage during high‑speed tufting unwinding. Handle bobbins gently and prevent scratch from sharp objects to reduce man‑made yarn defects.
Tufting unwinding tension shall be readjusted instead of directly adopting parameters for polypropylene or nylon yarn. Excessive tension stretches and destroys original crimp‑bulk structure, resulting in hard hand‑feel and insufficient pile fullness for finished carpets. Insufficient tension causes slack yarn, floating pile and missing tuft when tufting needles penetrate fabric. Small‑batch trial‑run helps optimize tension setting by observing pile appearance. Proper workshop temperature‑humidity adjustment suppresses static‑electric floating yarn and improves tufting continuity.
SORONA BCF yarn manufactured by Jiangsu Lingda Chemical Group completes full inspection including winding performance, bulkiness and color fastness before delivery. Sealed packaging lowers damage risks during transportation and storage. Tufting process suggestions are available for carpet manufacturers.
Reasonable storage protection, standardized handling and optimized tufting parameters retain original bulk and resilience advantages of SORONA yarn, cut downtime loss and improve overall quality of finished carpets.
