MANUFACTURE OF CRIMPED SOLVENT-SPUN CELLULOSE FIBRE AND QUALITY CONTROL DETECTION MEANS THEREFOR

摘要

Crimped solvent-spun cellulose fibre is that manufacture and inspection damage a kind of method, wherein: include: i) cellulose be dissolved in amine oxide solvent with formed heat cellulose solution, ii) hot cellulose solution is extruded through die head and forms a beam filament, III) tow is leached the amine oxide by water-bath water, independent variable) curling of tow makes in stuffer box it by apply curling, v) dry saturated steam is in penetrating stuffer box during crimping, duration) tow of curling leaves stuffer box and is passed through detection means, wherein VII) light beam be cast through travel path tow and receive by reception means in tow, holding device is to calibrate to initiation signal, if light beam is fuzzy. It is more than predetermined amount by traction variation. Equipment is also presented to the impaired crimped fibre of detection.
