Embodiment 1

[0021] Using terephthalic acid, ethylene glycol, and 2-carboxyethylphenylphosphinic acid as raw materials, the flame-retardant copolyester is synthesized by co-condensation. Disperse copper chrome black and 2-carboxyethylphenylphosphinic acid in ethylene glycol, add a small amount of silane coupling agent, stir at room temperature for 5 hours and then vacuum dry. The flame-retardant copolyester and the treated copper chrome black are granulated by melt blending to obtain the color masterbatch of the dope colored flame retardant copolyester, wherein the weight percentage of the copper chrome black is 20%. It is dried and mixed with the flame-retardant copolyester and then melt-spun to obtain the flame-retardant copolyester colored fiber, wherein the weight percentage of copper chrome black is 1%. The flame retardant properties, mechanical properties and thermal shrinkage properties of the fibers are listed in Table 1 and Table 2.

Embodiment 2

[0023] Using terephthalic acid, ethylene glycol, and 9,10-dihydro-9-oxa-10-phosphaphenanthrene succinic acid as raw materials, the flame-retardant copolyester is synthesized by co-condensation. Disperse titanium chrome brown and 9,10-dihydro-9-oxa-10-phosphaphenanthrene succinic acid in ethylene glycol, add a small amount of titanate coupling agent, stir at room temperature for 4 hours and then vacuum dry. The flame-retardant copolyester and the treated titanium chrome brown are melt-blended and granulated to obtain a color masterbatch of the dope-colored flame-retardant copolyester, wherein the weight percentage of the titanium chrome brown is 40%. It is dried and mixed with the flame-retardant copolyester and then melt-spun to obtain the flame-retardant copolyester colored fiber, wherein the weight percentage of copper chrome black is 2%. The flame retardant properties, mechanical properties and thermal shrinkage properties of the fibers are listed in Table 1 and Table 2. ...

Embodiment 3

[0025] Using terephthalic acid, butanediol, and 2-carboxyethyl methyl phosphate as raw materials, the flame-retardant copolyester is synthesized by polycondensation. Disperse cobalt blue and 2-carboxyethyl methyl phosphate in ethanol, add a small amount of magnesium stearate, stir at room temperature for 6 hours, and then vacuum dry. The flame-retardant copolyester and the treated cobalt blue are granulated by melt blending to obtain the dope colored flame-retardant copolyester color masterbatch, wherein the weight percentage of the cobalt blue is 30%. It is dried and mixed with the flame-retardant copolyester and then melt-spun to obtain the flame-retardant copolyester colored fiber, wherein the weight percentage of cobalt blue is 1.5%. The flame retardant properties, mechanical properties and thermal shrinkage properties of the fibers are listed in Table 1 and Table 2.

Abstract

The invention relates to a preparation method for stoste coloring anti-flaming copolyester fibers. The preparation method comprises the following steps: (1) mixing anti-flaming copolyester and pigments or dyes through melt blending to obtain stoste coloring anti-flaming copolyester color master batches, wherein the weight percent of the pigments or the dyes in the stoste coloring anti-flaming copolyester color master batches is 20-40 percent; and (2) producing the stoste coloring anti-flaming copolyester fibers by performing melt spinning on the stoste coloring anti-flaming copolyester color master batches and anti-flaming copolyester, wherein the weight percent of the pigments or the dyes in the stoste coloring anti-flaming copolyester fibers is 1-2 percent. According to the preparation method, the technology is simple, the production is flexible, the production period is short, the environment pollution is reduced, and a requirement on the anti-flaming performance of a material can be met.

Description

technical field [0001] The invention belongs to the field of flame-retardant dyeing, and in particular relates to a preparation method of dope-colored flame-retardant copolyester fibers. Background technique [0002] Polyester fiber is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol. Polyester fiber is mainly used for clothing and interior decoration. Chemical fiber blending; filaments can be processed to make elastic yarns, and can also be used to make tire cords, industrial ropes, transmission belts, filter cloths and fishing nets, etc., and can also be used as electrical insulation materials and artificial blood vessels. [0003] Polyester fiber has been widely used due to its high strength and good elasticity, but its application in many fields is limited due to its flammability. Therefore, the research on flame-retardant copolyester fiber has received extensive attention. And has successfully obt...
