Description

Technical Field

[0001] The invention relates to the technical field of polyester fiber preparation, and in particular to a method for preparing electric-shock microporous high-absorption and fast-discharge fibers, an electric-shock device, and fiber applications. Background Art

[0002] In recent years, fiber manufacturers in developed countries have achieved results in the research and development of functional textiles. Common functional fibers include moisture wicking, quick-drying, and antibacterial properties. However, the results are not ideal. For example, the moisture wicking effect of cross-shaped moisture wicking and quick-drying fibers often fails to meet the relevant INVISTA standards and requires hydrophilic treatment. However, the wash resistance after treatment is not long-lasting, and the antibacterial properties are significantly reduced after repeated washing.

[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and a method for preparing electric-shock microporous high-absorption and fast-discharge fibers, an electric-shock device and fiber applications are proposed. Summary of the invention

[0006] Furthermore, the electric shock treatment uses a voltage of 380 volts and a pulse frequency of 400 to 3800 mHz.

[0007] Furthermore, melt spinning is to melt a polymer at a certain temperature, and then gradually thin the molten polymer linear fluid through extrusion or pulling and finally form it into a fiber.

[0008] Furthermore, melt spinning is to input the molten blend into an extruder and heat it to reach the melting temperature.

[0009] Furthermore, an electric shock device is applied to the electric shock microporous high-absorption fast-discharge fiber preparation method, the electric shock device is installed at the outlet end of the spinneret, and the electric shock device includes a cylinder, and a plurality of electric shock rods are arranged outside the cylinder.

[0010] Furthermore, the electric shock rods are arranged in a circular array and are distributed in multiple circles up and down.

[0011] Furthermore, the electroshock microporous high-absorption and fast-discharge fiber prepared by the electroshock microporous high-absorption and fast-discharge fiber preparation method is applied to the fields of automobile interior, home textiles, clothing lining, building materials and non-woven fabrics. The present invention provides a method for preparing electric-shock microporous high-absorption and fast-discharge fibers, an electric-shock device, and fiber applications, which have the following beneficial effects: an electric-shock process is added to the original process flow, ordinary PET is made into a modified material with physical properties, a microporous structure is formed, the hygroscopicity and moisture discharge of the fiber are enhanced, high-absorption and fast-discharge, and a fiber substrate with balanced water molecules is formed, and high-performance functional materials are applied and developed for injection during the spinning process to better reflect the high-performance effect, and the loss rate of the water washing function is effectively controlled to achieve the effect of washing a hundred times, the bacterial growth is effectively controlled, and the inactivation of viruses is effectively protected.
