1Be anterior angle a under 17.5～18.5 degree, the pin tooth
2Be 20～24 degree, the left circles cambered surface β that cuts angle
1Be 46～50 degree, the right circles cambered surface β that cuts angle
2Be 16～18 degree, the tooth pitch P of pin tooth is 1.47～1.53 millimeters, pin transverse tooth thickness degree a is 0.06～0.08 millimeter, thickness at root of tooth b is 0.3 millimeter, crown height h is 0.60 millimeter, and pin tooth height overall H is 2.35～2.45 millimeters, and the density of pin tooth is 400 tooth/square inches, the base portion thickness W of described base portion 2 is 0.50～0.56 millimeter, and base portion height C is 1.2 millimeters; Described pin tooth 1 also can adopt have go up more greatly anterior angle and less in anterior angle, following three anterior angles that combine of anterior angle, anterior angle a on its pin tooth
1Be anterior angle a in 17.5～18.5 degree, the pin tooth
3Be 10～14 degree, anterior angle a under the pin tooth
2Be 12～14 degree.
Compared with prior art the utility model has the advantages that:
The utility model is because the pin tooth has adopted two anterior angles or three anterior angles, left and right sides double arc-curve face and the close configuration of little tooth, and selected reasonable process conditions for use according to experiment, thereby help of gripping, combing and the in time transfer of this card clothing to refinement jhouta suede fiber, avoided the wrapping phenomena of refinement jhouta suede fiber, be suitable for middling speed production, make yarn qualities can reach good level.
