Problems solved by technology

The advantage of this method is that the flame retardant performance is durable and washable, and the disadvantage is that the process is slightly complicated, the development cost of the copolymerized flame retardant is high, and the performance of the polyester is greatly affected.
[0004] (2) Blending flame retardant modification: This method is to blend and granulate ordinary polyester with flame retardants and then spin. Since it does not involve changes in the polymerization production process, it is simple and easy to operate, and the operating cost is low, but the fiber The flame retardant durability is worse than that of the copolymerization modification method
However, this method requires relatively high technical conditions, complicated process routes, and is difficult to industrialize.
[0007] (5) Flame retardant finishing of polyester fabric: The polyester fabric is dipped or padded in a solution containing a flame retardant, and then cross-linked to form a thin film on the outer layer of the fabric to achieve the flame retardant effect, but the flame retardant durability Not high, the fabric feels poor; at the same time, it has certain damage to the physical properties of the fiber, and the processing cost is high
[0008] Therefore, all there is certain defective in above-mentioned polyester fiber flame retardant method

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyester fiber pre-spinning flame-retardant masterbatch and a preparation method thereof. Background technique [0002] Polyester fiber refers to polyethylene terephthalate (PET) fiber, which has excellent performance, easy-to-obtain raw materials, and a wide range of uses. It is the fastest growing, highest-yield, and most widely used synthetic fiber. Synthetic fibers are known as the king of fibers in the 21st century. Polyester fibers are widely used in clothing, carpets and decorative fabrics due to their excellent properties such as high strength, dimensional stability, and chemical corrosion resistance. However, polyester fibers are flammable and flammable fibers, and flame retardant treatment of polyester fibers to reduce the risk of polyester fabrics in fire has become a research direction that has been widely concerned. Usually, the flame retardant of poly...
