The invention discloses a preparation method of flame retarding phosphorus-copolyester with better color phase. 4000-12000ppm of phosphorus- copolymerization flame retardant, which is calculated by phosphorus element, and 10-150ppm of three-valued phosphorus stabilizer, which is calculated by phosphorus element, are added during the preparation reaction. The hue value of the flame retarding phosphorus-copolyester prepared by the method is as follows: b is equal to minus 2 to 6, and L is equal to 60 to 90. The whiteness and the brightness of fabrics are good, and the fire resistance is excellent so as to reach M1 grade.
Description
Technical field: [0001] The invention relates to a preparation method of phase phosphorus-based copolymerized flame-retardant polyester. Background technique: [0002] Polyethylene terephthalate (PET) is a polyester with many excellent properties. It has the characteristics of high modulus, high strength, and good tensile elasticity. Its output is the largest in the world and its use is the most extensive. Polyethylene terephthalate fiber, referred to as polyester, is also the largest and most widely used variety of synthetic fibers. Polyester fiber has good mechanical strength and tensile properties, and is widely used in clothing, industry, transportation , Decorative materials. [0003] However, since polyethylene terephthalate is a combustible product, its application in fields requiring flame retardancy is greatly limited, such as military, aviation, transportation, hotels, entertainment venues, hospitals, cinemas, supermarkets, etc. Decorative materials and fire prot...
