Abstract

The invention relates to a colored glossy elastic polyester fine-denier carpet yarn and a preparation method. The carpet yarn is a plied yarn of 1,200 to 3,600dtex formed by at least two twisted polyester single yarns of 600 to 1,800dtex; and the twisted polyester single yarn is formed by multifilaments of a colored, glossy, fine-denier, profiled and three dimensional crimped polyester filament yarn. The preparation method comprises the steps: firstly, carrying out fibrous colored spinning procedures comprising spinning, false twist deformation and yarn doubling in the field of garment; secondly, obtaining three dimensional crimped polyester filament yarns with colors, fine-deniers and heteromorphous sections; and thirdly, obtaining colored, glossy and elastic polyester fine-denier carpetyarns through the post processing procedures comprising strand combing and sizing in the field of carpet yarns. The colored glossy elastic polyester fine-denier carpet yarn solves the problems of poor handfeel, resilience and dyeing property of the polyester fiber, not only can meet the requirements on the characteristics of carpet products, such as coverage, bulkiness, resilience, lodging resistance and foot-feel comfort, but also has the characteristics of high weather resistance, good color fastness, and energy-saving high-temperature high-pressure dyeing prevention.

Description

technical field [0001] The invention belongs to the technical field of carpet yarns, and in particular relates to a colored and photoelastic polyester fine-denier carpet yarn and a preparation method thereof. Background technique [0002] In recent years, the demand for carpets in the world has shown an increasing trend. my country's machine-made carpet industry started in the mid-1980s. In recent years, with the rapid development of tourism, hotel industry and real estate industry, the carpet market has continued to grow at a rate of more than 20%. It is estimated that the growth of carpets will remain strong in the next few years. With the improvement of living standards and the development of technology, carpets have become important decorations in many families. Although the scale of my country's machine-made carpet industry has expanded rapidly in recent years, the product structure has been continuously improved and the quality has been continuously improved.
