Abstract

The invention relates to a method for preparing anti-dripping polyester fibers. The method is characterized by comprising the following steps: 1) mixing materials: drying polyester chips, putting the dried polyester chips into an agitator, adding a crosslinking agent with mass being 0.5-5% that of the polyester chips and mixing in the agitator to obtain a co-mixture; 2) carrying out blending extrusion: adding the co-mixture to a twin-screw extruder for blending granulation to obtain granules; 3) melt spinning: drying the granules and then carrying out melt spinning by the existing melt spinning method of the polyester fibers to obtain primary anti-dripping polyester fibers; and 4) directly processing the primary anti-dripping polyester fibers with a 1.0-5MeV electron accelerator under theconditions that the irradiation dose is 10-50kGy, the beam current of the electron accelerator is 3-15mA and the irradiation time is 3-8s to obtain the anti-dripping polyester fibers. The method has the following beneficial effects: the anti-dripping polyester fibers are free of melting and dripping when burnt, can effectively resist dripping and can not release toxic gases or smoke; and the method is simple and practical.

Description

technical field

[0001] The invention belongs to the technical field of chemical fiber materials, in particular to a preparation method of anti-droplet polyester fiber. Background technique

[0002] Polyester fiber has the advantages of high modulus, high strength, high elasticity, good shape retention and heat resistance, and has become the most widely used and most consumed fiber variety. However, because polyester fiber is heated, melted, decomposed, burned, and has the phenomenon of melting and dripping, it is easy to cause secondary hazards and greatly restricts its use. The research on polyester fiber is of great significance. Contents of the invention

[0003] The object of the present invention is to provide a method for preparing anti-melt-dripping polyester fibers, and the polyester fibers prepared by the method have the characteristics of anti-melt-dripping.

[0004] In order to achieve the above object, the technical solution adopted by the present invention i...
