Embodiment 1
[0021] like Figure 1-3 As shown, a special licker-in carding card cloth for cotton-type silage degummed ramie fibers, a card cloth base 2 and needle teeth 1 evenly distributed on the card cloth base 2, wherein the needle teeth 1 adopt arc tooth tips and shallow Low-density configuration of teeth, the working angle α of the needle teeth 1 is 65°, the thickness b of the tooth tip is 0.20mm, the radius r of the tooth tip arc is 0.50mm, the arc angle ε is 3°, and the center arc point cut angle σ is 30°, the root thickness c is 0.32mm, the tooth depth h is 3.50mm, the density of the needle teeth is 26 teeth / square inch, the base thickness w is 0.63mm, and the base height d is 1.30mm. The cotton-type silage degummed ramie fiber with a fiber fineness of 1000Nm was used as the fiber raw material, the toll rate was 15%, and the fiber was fully pre-carded and transferred.
