Problems solved by technology

There is no special air flow channel, and the angle and direction of the air blowing fiber tow are not designed, so the output port is often blocked and the yarn is partially swollen.

Embodiment Construction

[0032] (1) Through the high-speed air puffing device, let the high-speed air flow continuously blow the functional fiber long yarn bundles, and control the airflow speed and blowing direction of the puffing device to fully separate each single yarn to form a bulky or spiral continuous fiber bundle .

[0033] (2) By adjusting the blowing speed and blowing angle, two basic types of bulked yarns can be made, namely bulky type and spiral type. The preparation of bulked yarns of different specifications can be realized by adjusting the air flow flowing into the air hole; by designing the angle of the air hole to vary between 15° and 75°, different angles of bulkers can be processed for selection. Through the parameters Preferably, the preparation of bulky and helical bulked yarns can be achieved.

[0034] (3) Through transverse stretching, the continuous fiber bundles are dispersed and stretched in the transverse direction, so that the continuous fiber bundles are dispersed and th...

Abstract

The invention discloses a continuous functional fiber bundle airflow dispersing and forming method and its equipment. Fully separated into monofilament state. Adjust the blowing speed to 20-50 m / s and the blowing angle to 15°-75° to produce two basic types of bulked yarns, bulky and spiral. Weaving with thicker bulky yarn with more pores can greatly improve the weaving efficiency, greatly reduce the weaving cost, and reduce the damage to the fibers. It is one of the effective methods to achieve large-scale and batch production by using continuous functional fiber bundles to disperse and rough weave. The continuous functional fiber prefabricated embryo body has a simple manufacturing process and can be formed into large-sized parts, which can reduce production costs and shorten the production cycle of products.

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...
