Manufacturing process of polyether-ester amide elastomer and elastic fiber |
摘要 |
A manufacturing process of continuously producing a polyether-ester amide elastomer, which is adapted for mass production and reducing manufacturing cost, includes the steps of melting a poly (tetra methylene ether) glycol reactant, a epsilon -caprolactam reactant and an adipic acid reactant, pre-polymerizing the melted reactants by esterification and ring-opening reaction to form a pre-polymer and highly polymerizing the pre-polymer to form the polyether-ester amide elastomer. The polyether-ester amide elastomer is specifically used as a raw ingredient for producing a polyether-ester amide elastic fiber by drying the polyether-ester amide elastomer in a drying device, extruding the dried polyether-ester amide elastomer by an extruder, and molten spinning the extruded polyether-ester amide elastomer to form the polyether-ester amide elastic fiber.
