Abstract

The invention relates to the field of chemical fibers, and provides a novel shrunk inflaming retarding complex fiber and a preparing method of the shrunk inflaming retarding complex fiber. According to the novel shrunk inflaming retarding complex fiber and the preparing method, the problem that after an inflaming retarding polyester fiber and a conventional high-shrinking yarn are compounded, the inflaming retarding performance of the fiber is reduced is solved. An inflaming retarding polyester pre-oriented yarn and an inflaming retarding type polyester high-shrinking yarn are compounded together at a network jet nozzle through false twisting deformation, two heat boxes are used for shaping, and then winding is carried out to obtain the shrunk inflaming retarding polyester complex fiber. The complex fiber has the good inflaming retarding performance.

Description

technical field [0001] The invention relates to the field of chemical fibers, in particular to a preparation method and application of compact flame-retardant polyester composite fibers. Background technique [0002] With the improvement of people's living standards, no matter the needs of life or decoration, it provides a broad world for the development of home textiles. [0003] At present, in the textile industry, flame-retardant polyester fibers are mostly used to compound with conventional high-shrinkage yarns, which can weave decorative fabrics with strong three-dimensional effect and novel styles, curtains with wrinkled surfaces, and carpets with tight bottom surfaces and good fluffiness. The textiles made by this method have a relatively obvious defect, that is, conventional high-shrinkage yarns do not have flame-retardant effect, and the flame-retardant properties of textiles will be reduced after compounding. Since some developed countries have formulated relevant...
