Embodiment Construction
[0024] The present invention selects suitable jade silkworm fiber by pure spinning 60-count high-count yarn with jade silkworm fiber. Conditions of jade silkworm fiber: specification 1.67dtex×38mm, dry breaking strength 2.18CN / dtex, wet breaking strength 1.12CN / dtex, dry breaking elongation 15%, moisture regain 8%, ultra-long fiber rate 0.3%, oil content 0.18%, defect 1.5 mg / 100g, double long fiber 1.2mg / 100g,
[0025] The production line of the present invention adopts A002C automatic cotton picker, A035C mixed opener, A036B porcupine opener, A092A double box feeder, A076C roll forming machine, A186D carding machine, A272F drawing frame two-pass, RD22C drawing frame Machine 1 (installed with autoleveling device), A456 roving frame, DTM129 spinning frame (installed with compact spinning device), 21C Japan Murata automatic winder.
[0026] The production steps are as follows: after the jade silkworm fiber is cleaned, carded, and drawn in three passes, the required yarn is prod...
