Problems solved by technology

Since the polyester fiber is basically peeled off by chemical action, the fiber sharpening takes a long time, and the mechanical properties of the fiber decrease a lot during the sharpening process.
The entire sharpening process requires a lot of labor, and personnel are required to repeatedly check the sharpening and peeling effect to confirm the quality
In addition, before sharpening, wire rods are mainly packaged by tow wrapping film, and most of them use PVC self-adhesive film. During the sharpening process, the PVC film degrades, and the heavy metal stabilizer in the film will be dispersed in the sharpening liquid at the same time. silk risk
In the ordinary chemical sharpening method, it takes about 1 hour to sharpen, the concentration of lye is 20%~70%, and the sharpening temperature needs to be greater than 100°C. Disadvantages such as difficulty in determining

Abstract

The invention discloses a production method for sharpening polyester monofilaments, which comprises the steps of: packaging and cutting the shaped polyester monofilaments to obtain silk cakes; placing the silk cakes in a container vertically or horizontally according to the fiber direction; In the sharpening groove of sharpening liquid, there is an ultrasonic generator in the sharpening groove, the ultrasonic generator is turned on and the power is set to 0.3-15kW, until a peak is formed, and a sharpened polyester monofilament is obtained; The sharpened polyester monofilaments described above were washed, dried and packaged. Through the above method, the production method of polyester monofilament sharpening of the present invention can reduce the processing time of sharpening, reduce the concentration of chemical agents, and can carry out sharpening treatment at both ends at the same time, thereby reducing energy consumption and production costs, and effectively improving Improve production efficiency and obtain high-quality sharpened wire.

Description

technical field [0001] The invention relates to the technical field of monofilament fibers, in particular to a production method for sharpening polyester monofilaments. Background technique [0002] At present, brush filaments mainly include polyester filaments and nylon filaments. Among polyester filaments, sharpened filaments have a large market share, and polyester raw materials are cheaper than nylon. The fiber diameter of the polyester fiber head after sharpening is After being made into brushes, the tip is relatively soft, and the part that is not sharpened has better stiffness and hardness, and has a long service life. At present, the sharpening treatment of polyester brush filaments mostly adopts chemical sharpening method. The reaction principle of chemical sharpening is that the hydrolysis reaction of polyester lye is a kind of hydrolysis and peeling reaction between solid and liquid phases, that is, the reaction liquid and the outer surface of the silk. Corrosion...
