    摘要: The present invention provides a sewing thread formed from poly(butylene terephthale) multifilament yarns, the sewing thread being characterized in that the sewing thread has an elastic recovery at 20% elongation of greater than or equal to 60%, a method of producing same, and the use of same. In the present invention a PBT yarn designates a yarn composed of a polyester that uses butylene terephthalate (tetramethylene terephthalate) repeating units as principal repeating units and that contains the butylene terephthalate repeating units in an amount of 50 mol-% or more, preferably 70 mol-% or more, even more preferably by 90 mol-% or more. The yarn made from PBT can contain a third component as an other acid component and/or glycol components and or other additives or colours in a total amount of 50 mol-% or less.
