Embodiment 1

[0052] Adipic acid (AA) was used as dibasic fatty acid. TPA, AA, and EG were mixed (TPA:AA:EG=600:315:50 by volume ratio) to prepare a slurry. The resulting slurry was continuously fed into a DE-1 reaction tank (see figure 1 ), wherein the DE-1 reaction tank contained 1.3 tons of molten base oligomer (which contained 8.7 mol% adipic acid based on the total dibasic acid), and the reaction tank was maintained at 255°C. The slurry was fed until the amount of polymer reached 1.5 tons and the esterification reaction was carried out for 30 minutes, and then 1.5 tons of oligomers were transferred to the DE-2 reaction tank using a metering pump. To this oligomer, add DES (its molecular weight is 356, dissolved in EG at a concentration of 35% by weight) represented by 1.3 mol% of the total dibasic acids (TPA, AA and DES) shown in Chemical Formula 1, wherein the chemical formula M in 1 is Na. Stir well and transfer the mixture to the polycondensation tank (see figure 1 ), and then a...

Embodiment 2

[0054] A polymer was prepared in the same manner as in Example 1, except that AA was replaced with azelaic acid (AZA) at 8.5 mol% of the total dibasic acids. The physical properties of the obtained polymers are listed in Table 1.

Embodiment 3

[0056] A polymer was prepared in the same manner as in Example 1, except that DES in which M was Li was added. The physical properties of the obtained polymers are listed in Table 1.

Abstract

The invention discloses atmospheric cationic dye dyeable copolyester polymer, a manufacturing method thereof and atmospheric cationic dye dyeable copolyester fibers using the same, particularly the invention provides atmospheric cationic dye dyeable copolyester polymer, a manufacturing method thereof and atmospheric cationic dye dyeable copolyester fibers using the same, wherein copolyester polymer includes dyadic fatty acid of 1-2 mol% accounting for diprotic acid and m-phthalic acid bis hydroxyl ethyl ester with metal sulfonate of 1.0-2.0 mol% accounting for diprotic acid.

Description

technical field [0001] The invention relates to a copolyester polymer which can be dyed with cationic dye under atmospheric pressure, its preparation method, and a copolyester fiber which can be dyed with cationic dye under atmospheric pressure prepared by using the copolyester polymer . Copolyester polymers and copolyester fibers that can be dyed with cationic dyes at atmospheric pressure and at temperatures of 100°C or lower can be produced by using inexpensive terephthalic acid (TPA) for polymerization. Copolyester polymers and copolyester fibers are of uniform quality and are inexpensive to produce. Background technique [0002] The following are some known copolyester polymers and copolyester fibers that can be dyed with cationic dyes at atmospheric pressure and at temperatures of 100°C or less. Japanese Patent Laid-Open No. 2002-284863 discloses a continuous polymerization method of polyester polymers dyeable with cationic dyes under atmospheric pressure. Specifical...
