The invention discloses a cashmere opening and 
carding line production 
system, which structurally comprises an industrial control computer, an opener and 8-16 
carding machines sequentially, wherein the 8-16 
carding machines are connected end to end and are arrayed in sequence, and the industrial control computer is used for monitoring the operation states of the opener and the carding machines in real time and performing 
automatic control; according to the line production sequence, each carding 
machine comprises a cashmere feeding mechanism used for conveying and feeding cashmere to a carding host, the carding host used for carrying out carding operation, and a 
moisture regain mechanism used for carrying out 
water spray moisture regain operation on carded cashmere sequentially. According to the cashmere opening and carding line production 
system and the process thereof, when opened and mixed cashmere enters each carding 
machine sequentially by virtue of conveying flat belts, the arrangement sequence of the carding machines are strictly controlled so as to ensure that the Xth carding 
machine is always used for carrying out the Xth carding operation, and the opening and carding operation can be efficiently finished. The feed quantity, the carding speed and the 
moisture regain rate of the carding machines can be automatically adjusted according to different properties of raw materials, and accordingly, the carding efficiency and quality of the cashmere can be improved.
