Abstract

The invention relates to a pressurized steam drawing machine for drawing fibers, which comprises a box body, filament bundle inlet and outlet windows arranged at the two ends of the box body, an inlet steam seal part arranged in the box body close to the filament bundle inlet window, an outlet stem seal part arranged in the box body close to the filament bundle outlet window, and a drawing chamber arranged in the box body and positioned between the inlet steam seal part and the outlet steam seal part, wherein the drawing chamber is formed by filling with a porous material; the box body comprises main thermal-insulation layer for keeping the temperature in the drawing chamber; a steam chamber is arranged between the main thermal-insulation layer and the drawing chamber; and the box body is provided with a steam pipe which connects the steam chamber and an external steam source. In the invention, that fiber protofilament bundles are drawn at a uniform and constant is ensured, and the high orientation and high strength of the protofilaments are improved effectively.

Description

technical field [0001] The invention relates to the technical field of carbon fiber precursor textile equipment, in particular to a pressurized water vapor drafting device related to high fiber drafting. Background technique [0002] Carbon fiber is a multi-disciplinary, multi-technical high-tech product. It has main characteristics such as high specific strength, high specific modulus, small specific gravity, high temperature resistance, chemical corrosion resistance, and radiation resistance, and has a series of comprehensive properties such as good thermal conductivity, electrical conductivity, damping, shock absorption, and noise reduction. Carbon fiber is also used in a wide range of fields, mainly in aerospace, automobile industry, cultural and sports equipment, and has good application prospects in medical equipment, new energy, civil engineering construction, high-strength mechanical equipment, and submarine oil. [0003] In the carbon fiber manufacturing process, h...
