Melt spinning spinneret is the core component of spinning device

Backup From:ZhenJiang New Tide Precision Machinery Co.,LTD Hit:1162 Time:2018-11-26

The importance of melt spinning spinneret and the design and selection of spinneret parameters such as shape, material and thickness.

The main function of spinneret in spunbonded nonwovens is to change the melt of polymer with viscous flow state into a small stream with a specific section shape through micropores and to form a filament after being cooled by air blowing or solidified by solidifying bath. Melt spinning spinneret is the core component of the spinning device. Due to the different requirements of production process, the characteristics of fiber forming and the different drawing ratio, the design of spinneret cannot be applied to the existing formula, and can only be explored and improved in the trial production process according to experience. The precondition of existing spinning equipment restricts the demand of spinning process, so it is particularly important for the design and selection of spinneret.

Zhenjiang new wave precision machinery co., ltd. is located in zhenjiang city, jiangsu province, which is the most dynamic Yangtze river delta economic circle in China. It is close to the golden port of the Yangtze river, zhenjiang international port in the north, national highway 312 in the south, beijing-shanghai high-speed railway, shanghai-nanjing intercity railway and shanghai-nanjing expressway, and only one hour's drive from nanjing airport and changzhou airport.
