In recent years, the domestic carbon fiber manufacturing industry has developed rapidly, and it has become a new type of material that has been developed in my country. In the carbon fiber production process, the quality of raw silk products is the key to ensuring the quality of carbon fiber products. In the production of raw silk technology, the high-precision spinning machine and its components can ensure the uniformity of the quality of the raw silk at the source, so that the fiber solidification molding path, molding time and molding temperature are controlled within the constant range required by the process.
The spinneret is processed by high-precision machine tools to ensure excellent dimensional accuracy, roughness and geometric shape. The material is made of high-strength and corrosion-resistant materials, and has undergone strict heat treatment, which has the advantages of corrosion resistance, high hardness, small deformation in long-term use, and good sealing performance. The spinneret is widely used in our lives, and the manufacture of precision machinery is inseparable from its use. What should be paid attention to in the application of the spinneret?
The spinneret is a spinneret for water flow entangling machine with high straightness. When the nonwoven fabric is produced by the water jet entangling method, the straightness of the jetted water flow greatly influences the production efficiency. The use needs to meet the following requirements: Generally, the side blowing speed of 0.300.40ms, the side blowing temperature of 2428 ℃ and the side blowing humidity of 6070 can make multiple monofilaments obtain a relatively uniform cooling tow running smoothly and uneven drying rate in. The impregnation of the staple fiber spinneret is to change the viscous polymer melt or solution through the micropores into a stream with a specific cross-sectional shape, and solidify through a coagulation medium such as air or a coagulation bath to form filaments.
