This invention relates to the field of new yarn materials technology, and more particularly to a thermally insulating biodegradable PLA napped composite yarn and its preparation method. The yarn uses core-sheath structure PLA filaments as the base yarn, with a core layer of PLA and a sheath layer of low-melting-point PLA or copolymer PLA. The monofilament cross-section is irregular and / or hollow. Air blowing is used to form loop / arc loop pile structures on the surface of the base yarn. Subsequently, under restricted shrinkage conditions, the pile is locked and shaped, with the locking temperature controlled above the sheath softening temperature and below the core melting peak, causing the sheath to soften locally at the contact points to form point-bonding locking points to fix the pile. The pile height quantile, coefficient of variation, and bulk index are detected online, and the airflow, feed difference, and shaping parameters are adjusted in a closed loop to achieve structural and performance stability during continuous production. This solution combines high bulk, high warmth retention, washability retention, and batch consistency.

The utility model relates to the switch technical field of hairdressing machine, especially a kind of lever switch and hairdressing machine, including the shell of hairdressing machine, the microswitch being arranged in shell, lever and linear elastic element, microswitch includes acceleration switch and deceleration switch, lever is passed through shell and is rotatably connected with shell, lever is configured to be able to be stirred from shell exterior, to swing around its rotation point to selectively trigger acceleration switch or deceleration switch, lever is elastically connected with shell by linear elastic element, to be used for providing the elastic reset force after the swing of lever, the problem that the existing hairdressing machine has security, aesthetic and operation convenience is not good is solved.
