Problems solved by technology

Although the polyester color fiber masterbatch is prepared by the masterbatch coloring method, the polyester color fiber masterbatch is used as a raw material for outdoor fabrics, and the outdoor fabrics will fade in a short time after being exposed to wind and sun. Low color fastness is still a problem that needs to be solved urgently

Abstract

The invention provides a high-light-fastness polyester color fiber master batch and a preparation method thereof, the high-light-fastness polyester color fiber master batch is applied to outdoor cloth, and comprises the following formula components in percentage by weight: 50-70% of inorganic toner and organic toner; 27-50% of thermoplastic resin; 1%-3% of an additive; and the balance an anti-ultraviolet agent; according to the high-light-fastness polyester color fiber master batch and the preparation method thereof, the high-light-fastness polyester color fiber master batch is applied to outdoor cloth, the cloth is high in color fastness after being solarized for a long time, the fiber physical property degradation speed is low, and the service life of the cloth is remarkably prolonged.

Description

technical field [0001] The invention relates to the technical field of polyester colored fiber masterbatch, in particular to a high-solar polyester colored fiber masterbatch and a preparation method thereof. Background technique [0002] Polyethylene terephthalate, abbreviated as PET in English, is one of the synthetic polymers. With the rapid development of the petrochemical industry, PET is widely used in engineering plastics and synthetic fibers due to its easy availability of raw materials, simple polymerization process, high strength, chemical stability, spinnability and low cost. Polyethylene terephthalate fiber (abbreviated as PET fiber in English, commonly known as polyester), has a wide range of uses due to its excellent comprehensive performance, low cost and good performance. It far surpasses other synthetic fibers and always ranks first among the "four major fibers". (The four major fibers are polyester, nylon, vinylon, and polypropylene). [0003] The most com...
