Abstract

The invention discloses a continuous functional fiber bundle air flow scattering and forming method and equipment thereof. The method comprises the following steps that high-speed airflow passes through a puffing machine nozzle through a high-speed airflow puffing machine and continuously blows long functional fiber yarn bundles, and each single yarn is sufficiently separated to be in the single filament state. The blowing speed is adjusted to be 20-50 m / s, the blowing angle is from 15 degrees to 75 degrees, and two basic kinds of bulked yarns can be prepared, namely, the bulk type bulked yarns and the spiral type bulked yarns. The bulked yarns which are thick and are provided with a lot of air holes are woven, the weaving efficiency can be greatly improved, the weaving cost is greatly reduced, and damage to fibers is reduced. The continuous functional fiber bundles are scattered to be woven roughly, and the method is one of the effective methods for achieving large-scale and batch production. The continuous functional fiber prefabricating green body manufacturing technology is simple, large-sized pieces can be formed, the production cost can be reduced, and the production cycle of products is shortened.

Description

Technical field:

[0001] The invention relates to a method for dispersing and forming functional fiber bundles and its equipment, in particular to a method for forming bulked yarn by continuously spraying functional fiber bundles through a bulking device with high-speed airflow. Background technique:

[0002] Continuous functional fiber long yarn bundles, chopped yarns and their fiber products have played a huge role in national defense and civil construction. However, there are certain defects in the continuous functional fiber long yarn bundle and its products in many engineering applications, and the characteristic advantages of each single yarn cannot be brought into play. Generally, in the yarn forming process, it is necessary to assemble each single yarn into a bundle yarn through a sizing agent or a sizing agent. The surface of the bundle yarn contains a certain amount of sizing agent. During the compounding process, the resin or other matrix is ​​only mostly covered o...
