The invention provides equipment and a method for producing easy-to-dye PET (Polyethylene Terephthalate) and PTT (Polytrimethylene Terephthalate) eccentric composite filament fibers, and relates to the technical field of fiber spinning. The equipment for producing the easy-to-dye PET and PTT eccentric composite filament fibers comprises a spinning cabinet, the pressurizing cabinet is fixedly connected to the upper wall of the spinning cabinet; and the feeding cabinet is fixedly connected to the upper wall of the pressurizing cabinet. According to the invention, the alkaline earth metal compound can enable the surface of the tow to form micropores with proper sizes, the dyeing effect of the obtained tow finished product and the fabric thereof is improved, meanwhile, the polymer has high polymerization degree, high softening point and good spinnability, the component B tow forms a skin layer, and the component A tow forms a core layer. The composite fiber tows are not directly exposed on the surface of the braided fabric, so that uneven dyeing is avoided, the quick release structure is matched with the rotating structure, the quick release plate can be quickly separated from the spinning box and is not completely separated when maintenance is needed, the spinneret plate can be directly cleaned and maintained, and the maintenance work is very convenient.
Description
technical field [0001] The invention relates to the technical field of fiber spinning, in particular to an equipment and method for producing easily dyeable PET and PTT eccentric composite filament fibers. Background technique [0002] Sheath-core composite fiber is composed of two polymers in the arrangement of skin and inner core along the fiber axis. Sheath-core composite fiber is mainly concentric composite and eccentric composite, such as PET&PTT skin-core composite fiber. It has good elastic modulus, soft hand feeling and firmness, and excellent dyeability. This is due to the fact that the advantages of easy dyeing of PTT fiber are fully utilized, and normal pressure dyeing equipment can be used, and the operation is more convenient. Usually, the color is more complete and the color is bright. , Acid dyes with good color fastness and disperse dyes with good level dyeing, PET&PTT eccentric composite filaments, because PET and PTT have eccentric composite structures with...
