Problems solved by technology

[0004] Bright FDY products are mainly round holes and triangular shapes. The market supply tends to be saturated, and the profit margin is declining year by year. Some companies have to use the equipment of the FDY production line to produce POY varieties. The production cost is high and the product quality is poor.

Abstract

The invention provides a production method of an 83dtex / 72f lustrous fine-denier flat FDY fiber. The method comprises the steps that a lustrous polyester melt as a raw material passes through a melt conveying pipeline and is pressurized through a booster pump and then conveyed into a melt cooler for cooling; the cooled melt is conveyed into a spinning manifold, then enters a metering pump through a melt distribution pipeline and conveyed into a spinning component through the melt distribution pipeline after precise metering; the melt is squeezed out through a spinneret plate after filtration and subjected to cooling solidification through a circular blow air duct to generate an as-spun fiber; the as-spun fiber sequentially passes through a spinning pre-interlacer, a first roller, second and third hot rollers and fourth and fifth hot rollers for drawing and setting, then sequentially passes through an oil atomizer for finishing, a sixth roller, a main interlacer and a seventh roller, and finally is packaged for formation. Based on an original device platform, a novel variety of fiber which is high in technical difficulty and high in additional value of products is produced through technology improvement and innovation, the fiber is large in product shaped degree, and the enterprise competitiveness is improved.

Description

[0001] (1) Technical field [0002] The invention relates to a production method of 83dtex / 72f glossy fine denier flat FDY fiber. [0003] (2) Background technology [0004] Bright FDY products are mainly round holes and triangular irregular shapes. The market supply tends to be saturated, and the profit margin is declining year by year. Some companies have to use FDY production line equipment to produce POY varieties, resulting in high production costs and poor product quality. However, we use the WINGS-FDY production line to take advantage of new equipment and make bold technical attempts to produce 83dtex / 72f fine denier FDY flat fibers with relatively high technical difficulty, increasing economic benefits for the enterprise. 83dtex / 72f fine denier FDY flat fiber has a slender and flat cross-sectional shape, and the fabric made of it has good pile uprightness and full hand feeling. [0005] (3) Contents of the invention [0006] In order to develop the potential of the ex...
