False Twisting Machine S/Z Twist Switching | Adjust Yarn Twist Direction from Xinchang Lanxiang Machinery S/Z twist switching module on false twisting machine enables production of both S-twist and Z-twist DTY; Xinchang Lanxiang Machinery mechanical switching unit adjusts twist direction without full line rework. S twist and Z twist yarn have different fabric shrinkage and hand feel. Fabric woven with mixed S/Z yarn reduces skew deformation by 35% compared to single twist direction fabric. Twist level can be adjusted within 220–480 twists per meter. Twist deviation is controlled within ±4 twists/m, which maintains consistent fabric dimensional stability after dyeing. Switching between S and Z twist takes roughly 18 minutes per machine frame. No need to replace friction disc group when changing twist direction. The switching mechanism adopts electromagnetic locking. Locking failure rate stays below 0.08% under 10,000 switching cycles in durability testing. Xinchang Lanxiang Machinery S/Z twist false twisting machine holds CE and ISO9001 certification. 720-hour continuous test achieves uptime of 97.9%. Exported to 13 textile countries. Standard delivery lead time is 60 working days after deposit. Machine packed in seaworthy plywood crates. FOB, CIF and CFR trade terms available. Customization can add automatic twist switching program linked with recipe storage. OEM mechanical locking structure modification is available upon special requirement. On-site installation and commissioning takes 7–10 working days. Operator training covers twist level calibration, S/Z switching operation and mechanism inspection. Core twist switching assembly and main machine parts carry 12-month warranty. Remote online diagnosis replies within 24 hours. Field engineer service available within 7 working days. A common misunderstanding: higher twist level always improves fabric strength. Twist exceeding 480 twists/m lowers yarn tenacity by 21% and increases yarn breakage during weaving.

FAQ
