Disclosed is a foamed synthetic fiber characterized in that an organic solvent solution of a thermoplastic polymer admixed with 3-100 weight percent of a compound scarcely soluble or insoluble in the aqueous coagulating bath for wet spinning, which is liquid under normal pressure and has a boiling point of 120.degree. C. or less, as foaming agent is injected as spinning dope into said aqueous coagulating bath and it is foamed in a drying atmosphere at the boiling point or more of the foaming agent and 100.degree. C. or more and has an expansion ratio of 3 percent or more, and the manufacturing method thereof. The foamed synthetic fiber of the present invention is light and bulky, being excellent in warmth-keeping and heat-insulating performance with its appearance, touch and development of color similar to those of an animal hair.

Foamed synthetic fiber and its manufacturing method

The present invention provides pile compositions comprising 2% by weight or more of porous expanded fibers with expansion ratio 3% or higher as fibers composing the pile part. This invention enables providing pile compositions which give excellent animal hair like feeling and external appearance; that is, pile part's lightness, bulkiness, soft touch, elasticity, coloring and loosenability.
