Beschreibung
Zusammenfassung:	The present invention relates to the technical field of polyamide materials, and provides a polyamide 56 pre-oriented yarn and a polyamide 56 draw textured yarn with a low shrinkage in boiling water, a process for producing the same and a use thereof. The raw materials for producing the polyamide 56 fiber comprise 1,5-pentane diamine and adipic acid, or a polyamide 56 resin obtained by polymerizing 1,5-pentane diamine monomer and adipic acid monomer; wherein the polyamide 56 fiber has a shrinkage in boiling water of 9% or less, wherein the polyamide 56 fiber comprises a polyamide 56 pre-oriented yarn with a low shrinkage in boiling water and a polyamide 56 draw textured yarn with a low shrinkage in boiling water. The polyamide 56 fiber has good mechanical properties, dyeing uniformity and dimensional stability. The process for producing the polyamide 56 fiber does not require modification to existing equipments for texturing polyamide fibers and thus reduces production costs.
