Abstract

The invention relates to a preparation method for preparing a gripper head for a rapier loom from glass fiber reinforced polycarbonate thermoplastic resin composite. The gripper head is prepared from the glass fiber reinforced polycarbonate thermoplastic resin composite, and the glass fiber reinforced polycarbonate thermoplastic resin composite is prepared through blending and granulation of glass fiber and polycarbonate thermoplastic resin by means of a double-screw extruder; the gripper head for the rapier loom is prepared through injection molding of the prepared glass fiber reinforced polycarbonate thermoplastic resin composite by means of an injection molding machine; special surface modification treatment is performed in advance before blending of the glass fiber and polycarbonate, and the gripper head which has good wear resistance and fatigue resistance, high bending resistance, compression resistance, tensile resistance and impact strength, high thermal resistance and long service life and is used for the rapier loom is prepared.

Description

technical field [0001] The invention relates to a textile machinery component, in particular to a method for preparing a rapier head from a glass fiber reinforced polycarbonate thermoplastic resin composite material Background technique [0002] With the development of new textile machinery in our country, the quality requirements for parts in textile machinery are getting higher and higher. These parts must not only have good physical and mechanical properties, but also have excellent processability and low production efficiency. cost. [0003] At present, among all kinds of new looms used in the textile industry, the rapier loom has simple structure and wide adaptability, and has been widely used. On the existing rapier looms, since the front gripper of the rapier head adopts the design of the back-shaped hook and the elastic rod to passively clamp the weft yarn, the rapier head back-shaped hook at high speed retreats when the rapier loom is weaving. The hook hooks the w...
