Process for producing polyester fiber and polyester fiber therefrom |
摘要 |
<p>This invention relates to a process for producing polyester fibers with enhanced dyeability, lesser elongation and greater strength, which comprises combining 2-methyl-1,3-propanediol into a mixture containing terephthalic acid, or an alkyl ester thereof, and a (C2-6) alkanediol, and carrying out polymerisation. The resultant polyester copolymer is then spun to produce polyester fibers. This invention also relates to the polyester fibers produced by this process. These polyester fibers exhibit enhanced dyeability, lesser elongation and greater strength than unimproved polyester fibers.</p> |
