Abstract

The present invention discloses excellent flame-retardant polyester and preparation method of the flame-retardant polyester. The product comprises polyester and the organic silicone copolymer as well as organic phosphorus copolymer contained in the polyester. The preparation process comprises the synthesis of the polyester, etherifying of the synthesized polyester or the polycondensation phase during which organic silicon monomer and organic phosphor monomer are added. The present invention takes use of silicon monomer and organic phosphor monomer for copolymerization with the polyester. The polyester is endowed with excellent flame-retardant performance. The polyester can meet the no-drop requirements during the flame-retardant process. The product by the present invention is no-drop-typed flame-retardant polyester, which can be used to manufacture polyester fiber and correspondent woven fabric or weaving fabric textile or nonwoven cloth and so on.

Description

Technical field:

[0001] The invention relates to a polyester and a production method, which is a flame-retardant polyester and a production method. Background technique:

[0002] Polyester products, especially polyethylene terephthalate, are widely used in the field of manufacturing fibers and their products due to their excellent properties, and have become the largest output product in the chemical fiber industry in the world. With the improvement of human's requirements for the quality of life and the enhancement of self-protection awareness, the requirements for polyester products are also getting higher and higher, especially the requirements for safety in use, such as the requirement that polyester products have good flame retardant properties , so that in the case of fire, it will not bring greater disasters to humans, so various companies have developed polyester with flame retardant properties.

[0003] At present, the flame retardant technologies used by various c...
