Abstract

The invention provides polyphenylene sulfide navy-blue masterbatches, a polyphenylene sulfide navy-blue colored fiber and preparation methods of the polyphenylene sulfide navy-blue masterbatches and the polyphenylene sulfide navy-blue colored fiber. The polyphenylene sulfide masterbatches are prepared from the following raw materials: colorant nano-powder, a hyperdispersant, an antioxidant and polyphenylene sulfide powder; and the colorant nano-powder is prepared from the following raw materials: ultramarine, phthalocyanine blue 15:3 and carbon black. According to the raw material formula, thepolyphenylene sulfide navy-blue colored fiber adopted by the preparation method is prepared from the following raw materials in percentage by weight: 2%-5% of the polyphenylene sulfide masterbatchesand 95%-98% of polyphenylene sulfide granules, and the sum of the weight percentages of the raw materials is 100%. Colorants are compounded to prepare the polyphenylene sulfide masterbatches, fiber discoloring before spinning is realized by preparing the masterbatches, and the problems that traditionally, the color fastness of fiber dyeing after spinning is low, and three-waste pollution is proneto being caused are solved. The formula of the polyphenylene sulfide masterbatches is optimized, the colorant, namely the black colorant, organic pigment, namely the phthalocyanine blue and the ultramarine are selected to be compounded, and the compounded colorants act synergistically.

Description

technical field [0001] The invention belongs to the field of fiber dyeing and relates to polyphenylene sulfide fibers, in particular to a polyphenylene sulfide navy blue masterbatch, colored fibers and a preparation method. Background technique [0002] With the development in recent years, polyphenylene sulfide (PPS) fiber, as a new type of high-performance special functional fiber, has great application prospects in the textile industry. People pay attention to the comfort and safety of clothing in special working environments, such as high temperature and cold, toxic, chemically corrosive and other environments, it is difficult for ordinary fiber clothing to protect the health and safety of workers in this special environment . However, polyphenylene sulfide fiber has its own flame retardancy, chemical corrosion resistance, high temperature resistance and excellent physical and mechanical properties, and is used to prepare special protective clothing to reduce personal i...
