Physical Morphology
Spontaneous micro-structural peeling during mechanical processing yields microscopic cellulosic particulates that detach from spun-down filament surfaces under aggressive shear forces. Lyocell fibrillated fragments detach most prominently during wet beating and high-intensity jet dyeing stages where swelling agents accelerate outer skin splitting. These detached micro-fibres migrate through liquor circulation paths in industrial rotary washers and deposit onto adjacent garment panels during batch processing.
Extraction Protocol
Gravimetric quantification relies on selective enzymatic hydrolysis followed by filtration across standardized mesh screens to isolate suspended cellulosic detritus from process effluent. Analytical technicians sample liquor immediately following enzymatic polishing runs to capture maximum particulate loads before rinse cycles dilute the recovery stream. Duplicate specimens undergo vacuum drying at a controlled temperature to eliminate moisture bias prior to final mass determination on a micro-balance.
Defect Classification
Surface adhesion of these detached micro-structures alters fabric hand by creating a peach-skin tactile profile that consumers often mistake for deliberate brushing. Quality control auditors grade batches by counting adhered particulate clusters per square decimetre under low-magnification stereo-microscopes at the final finishing inspection table. Rejection thresholds apply whenever micro-fibril density exceeds allowable limits established for high-luster shirting fabrics intended for reactive printing.
Remediation Parameters
Optimizing refining disc clearance reduces longitudinal splitting of the solvent-spun cellulose before yarn formation reaches the sizing department. Chemical cross-linking agents applied during pad-dry-cure operations immobilize loose surface fibrils and prevent subsequent detachment during subsequent consumer laundering cycles. Mill operators adjust mechanical agitation speeds downward in wet processing baths whenever raw material lot variability indicates heightened susceptibility to axial splitting.
