Colored polyester filament yarn with diamond blinking effect and method for manufacturing colored polyester filament yarn

Abstract

The invention discloses a colored polyester filament yarn with a diamond blinking effect and a method for manufacturing the colored polyester filament yarn. The method includes steps of preliminarily crystallizing and drying super-lustrous polyester chips; melting and extruding the dried super-lustrous polyester chips via a screw extruder and simultaneously injecting color master-batches into the screw extruder by a color master-batch injector; and spinning to obtain a winding yarn; laterally blowing wind to cool down the spun winding yarn; applying oil to the winding yarn by an oiler; feeding the winding yarn to perform drafting for the winding yarn in a drafting procedure; and adding the winding yarn into a net and winding and molding the winding yarn. The colored polyester filament yarn and the method have the advantages that the polyester filament yarn realizes a bright and lustrous effect, the length-width ratio of a flat hole pattern is increased to the greatest extent on the premise of guaranteeing high spinnability, and the style of a product can be affected greatly (a fabric is in a scaly style); fuzziness and broken ends can be greatly reduced by the method; and energy consumption and the production cast can be greatly reduced.

Description

Technical field: [0001] The invention is an improvement to the polyester filament used for clothing and home textile fabrics, and relates to a colored polyester filament with a diamond flashing effect and a preparation method thereof. In particular, it relates to a polyester flat filament dyed with a stock solution and has a diamond-like glittering effect and a preparation method thereof. technical background: [0002] Functional textile varieties are constantly coming out. With the improvement of modern living standards, fashion and functionalization of clothing are the development trend. The filaments used in this type of fabric require good dyeing performance, bright color, no fading, good gloss, and good drape. Personal style. [0003] At present, most polyester filaments have to be dyed and finalized after weaving and finishing. The environmental pollution is serious, the cost of pollution control is high, and the color fastness is poor. The fabric is easy to fade afte...

AI Technical Summary

Problems solved by technology

[0003] At present, most polyester filaments have to be dyed and finalized after weaving and finishing. The environmental pollution is serious, the cost of pollution control is high, and the color fastness is poor. The fabric is easy to fade after use, which affects the wearing effect.

At present, most of the raw materials are produced on imported spinning equipment, that is, on FDY spinning equipment. However, due to the high price of imported equipment, large investment, high technology, management and operation requirements, the production cost is high.
