Discussion on the process of melt direct spinning fine denier polyester fully drawn yarn 22 dtex/48 f
With the development and progress of society,people no longer only focus on practicality and durability of clothing,but also have higher requirements for its comfort and aesthetics.In the market,there is an urgent demand for new chemical fiber materials with high added value,and fine denier polyester fully drawn yarn(FDY)is highly favored due to its excellent performance.Due to its low linear density and fine single filament,the production of fine denier polyester FDY is difficult,and there are not many manufacturers capable of producing high-quality fine denier polyester FDY.At present,the market demand for fine denier polyester FDY is rapidly increasing.This article introduces the adjustment experiment of the melt direct spinning fine denier polyester FDY 22 dtex/48 f process,and explores the effects of melt quality,spinning temperature,spinning components,cooling and oiling,setting of the height of the slow cooling zone and the temperature of the slow cooler,temperature and speed of drawing and shaping,and network pressure on the production and product quality of fine denier polyester FDY.The results show that under appropriate process conditions,high-quality fine denier polyester FDY 22 dtex/48 f can be produced,and the production status is stable.
