Problems solved by technology

[0008] However, due to the increase of phosphorus content in polyester, the color of polyester chips and polyester fibers will deteriorate, the product will turn yellow and the L value will decrease, and the color tone of the fibers will not be good.
The quality of the fiber tone will affect the tone of the original fabric. The difference in the hue of the original fabric makes its brightness and lightness not obvious, thus affecting the effect after dyeing, making the lightness and color of the dyed fabric worse, affecting the appearance, and difficult to meet the needs of users.
[0009] Patent CN200480038764.4 discloses a flame retardant with good color tone. The patent believes that the color tone of the flame retardant itself is poor. Adding an antioxidant can improve the color tone of the flame retardant when preparing the flame retardant, but this method cannot be used in the final product. To improve the color tone of polyester chips, the b value of polyester obtained by this method is still poor

Embodiment 1

[0056] The polymerization of flame-retardant copolymer masterbatch is completed on a 150kg two-tank polymerization production line, one esterification kettle and one polycondensation kettle. After beating 130kg of terephthalic acid and 56kg of ethylene glycol in the beating tank, they are fed into the esterification tank containing half of the previous batch of esterification liquid for esterification. After the esterification distillate reaches 90% of the theoretical value Stop the esterification, move the oligomer into the polycondensation kettle, and then add the stabilizer phosphoric acid so that the amount is 10 ppm relative to the produced flame-retardant copolymer masterbatch, and the amount of the toner is cobalt acetate. The flame-retardant copolymer masterbatch is 10ppm based on cobalt atoms; 400ppm of antimony trioxide is added, and 1000ppm of antioxidants are added; FR-100 (structure C) is added to make the amount of 18000ppm based on phosphorus atoms. After all the...

Embodiment 2

[0060] The flame retardant FR-100 (Structural Formula C) was added so that the amount was 15000 ppm in terms of phosphorus atom, and the others were the same as Example 1. The detailed test data is in the attached table.

Embodiment 3

[0062] The flame retardant FR-100 (Structural Formula C) was added so that the amount was 30000 ppm in terms of phosphorus atom, and the weight ratio of flame retardant masterbatch to semi-dull PET was 1:4, and the others were the same as in Example 1. The detailed test data is in the attached table.

Abstract

The invention discloses a flame-retardant polyester fiber and a production method thereof; the flame-retardant polyester fiber is obtained by mixing and spinning flame-retardant copolymerization master batch and common polyester; the flame-retardant polyester fiber has a phosphorus content of 5000-7500 ppm, has excellent flame retardancy, a good color, a high melting point, superior heat resistance, and low cost, and is widely applicable to decoration material fields such as curtains, carpets, and materials and equipment in vehicles.

Description

Technical field [0001] The invention relates to a flame-retardant polyester fiber and a production method thereof. Background technique [0002] Polyethylene terephthalate (PET) has the characteristics of high modulus, high strength, and good tensile elasticity. Among polyesters, it has the largest output in the world and the most extensive use. Polyethylene terephthalate fiber, abbreviated as polyester, is also the variety with the largest output and most versatile synthetic fibers. Polyester fiber has good mechanical strength and tensile properties and is widely used in clothing, industry, and transportation. , Decorative materials and other fields. [0003] However, because polyethylene terephthalate fiber is a combustible product, it greatly limits its application in fields requiring flame retardancy, such as military, aviation, transportation, hotels, restaurants, entertainment venues, hospitals, cinemas, supermarkets, etc. Decoration materials, fire protection, etc. Fires ...
