Abstract

The present invention proposes a melt-blown nozzle for industrial textile products and its spinneret, including a forming plate, the forming plate is densely covered with spinneret holes, and the forming plate is provided with a steam release device to the surface of the forming plate. The steam generator is used to solve the technical problem that the cooling speed of the inner and outer fiber bundles is inconsistent.

Description

technical field [0001] The invention relates to a melt-blown nozzle for industrial textile products and a spinneret thereof. Background technique [0002] Polyethylene terephthalate (PET) has the characteristics of high mechanical properties, wear resistance, creep resistance and electrical insulation properties, and is rich in raw materials. It is the fastest growing synthetic fiber variety with the largest production capacity in recent years. PET microfiber is a high-tech and high-value-added product with excellent performance and unique style. It has broad application prospects in the fields of medium and high-end fabrics, construction, biomedicine, industrial filtration, military protection, and environmental protection. There are many ways to prepare PET ultrafine fibers, among which the melt spinning method is one of the most used in industrial production, and the spinneret is an indispensable part of the melt spinning method. [0003] For example, the invention paten...
