Abstract

The invention discloses a production technology of a superfine, velvet and fluffy fiber. The production technology comprises the following steps: polyester melt preparation, pipeline transportation, processing using a booster pump, processing using a melt cooler, processing using a static mixer, processing using a melt distributing valve, processing using a spinning box, processing using meteringpump, processing using a spinning assembly, processing using a spinneret, ring blowing air duct cooling, oil nozzle oiling, processing using a channel, processing using a pre-network, processing usinga GR1GR2 guide plate, winding forming, and doffing and packaging. The invention has the advantages of effectiveness in prevention of low temperature of the surface of the spinneret, uniformity in filament bundling oiling, and stability in the yarn levelness and strength of the product.

Description

technical field [0001] The invention relates to a production process of fibers, in particular to a production process of superfine soft velvet fluffy fibers. Background technique [0002] At present, the domestic social economy is developing rapidly, science and technology are advancing by leaps and bounds, and the types of chemical fiber products are changing with each passing day. The functional requirements for the fabrics of chemical fiber products are also getting higher and higher. Differentiation is the biggest task facing the company at present. Only by developing unique differentiated fibers with high added value, which are innovative and unique in the industry, can enterprises gain a foothold in the market. Based on advanced production equipment and mature production technology, Hengteng Company has developed a brand product with unique properties of ultra-fine soft fluffy fiber on a single board and single cake through unremitting efforts. [0003] Ultra-fine, s...
