  Abstract:In order to achieve fine carding and improve the leveling accuracy and amplitude of carding，the process，structure and the current status of cotton layer thickness detection technology at the rear of carding machine are introduced.The shortcomings of cotton spinning carding machine and non-woven carding machine in holding the feeding cotton layer，fiber carding and cotton layer thickness detection are analyzed.The process optimization of “thin feeding and fast forwarding”，fine carding，balanced holding and accurate detection of rear feeding cotton carding are proposed.The technical structure using airbag-type pressurized feeding cotton layer subdivision holding，cotton layer linear density liquid flow conduction detection technology and carding machine rear feeding pre-drafting process is designed.It is pointed out that the technology of holding the subdivision of air-pressurized feeding layer and measuring the thickness of the cotton layer by liquid flow conduction can hold the ultra-thin feeding layer more effectively，comb the small quantitative cotton layer more finely，and detect the transverse average thickness of the feeding cotton layer more accurately.The pre-drafting process combined with the subdivided holding technology creates conditions for improving fiber orientation，implementing “thin feeding and fast forwarding” and fine carding processes，as well as creating software and-hardware conditions for optimizing fiber web，sliver quality，and subsequent process configuration and finished product quality.
Key Words:rear process of carding machine；thin feeding and fast forwarding；subdivided pneumatic pressure holding；pre-drafting process of feeding cotton layer；auto-leveling；liquid flow conduction；fine carding
