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

[0024] Such as Figure 1-3 As shown, a special licker-in card clothing for silage degummed ramie fibers, the card clothing base 2 and the needle teeth 1 evenly distributed on the card clothing base 2, wherein the card clothing adopts arc tooth tip and shallow tooth low dense configuration, the working angle α of the needle tooth 1 is 70°, the tooth tip thickness b is 0.22mm, the tooth tip arc radius r is 0.46mm, the arc angle ε is 3°, and the central arc point cutting angle σ is 23 °, the root thickness c is 0.32mm, the tooth depth h is 3.50mm, the density of the pin teeth is 27 teeth / square inch, the base thickness w is 0.65mm, and the base height d is 1.40mm. Cotton-type silage degummed ramie fibers with a fiber fineness of 1200 Nm were used as fiber raw materials. The tow rate was 13%, and the fibers were well pre-carded and transferred.
[0025] The cotton-type silage degummed ramie fiber with a fineness of 1200Nm is carded with the conventional licker-in card clothing. ...
Embodiment 3
[0027] Such as Figure 1-3 As shown, a special licker-in card clothing for silage degummed ramie fibers, the card clothing base 2 and the needle teeth 1 evenly distributed on the card clothing base 2, wherein the card clothing adopts arc tooth tip and shallow tooth low The working angle α of the needle tooth 1 is 75°, the tooth tip thickness b is 0.21mm, the tooth tip arc radius r is 0.45mm, the arc angle ε is 4°, and the central arc point cutting angle σ is 18 °, the tooth root thickness c is 0.32mm, the tooth depth h is 3.40mm, the pin tooth density is 27 teeth / square inch, the base thickness w is 0.64mm, and the base height d is 1.37mm. Cotton-type silage degummed ramie fibers with a fiber fineness of 1400 Nm were used as fiber raw materials. The tow rate was 12%, and the fibers were well pre-carded and transferred.
[0028] The cotton-type silage degummed ramie fiber with a fineness of 1400Nm is carded with a conventional licker-in card clothing. Since the fiber contains...
