摘要： 57 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°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°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.

摘要： Description is made of an increased volume synthetic fibre consisting of a porous central core and a large number of short porous lateral threads integral with the core and distributed along the whole length of the fibre so as to form a voluminous branching struc­ture. There is also a description of the procedure used to produce the fibre, which consists of the mixing of a synthetic polymer with an inflating agent which expands when heated, the spinning by means of melting the mixture which results in the inflation and fring­ing of the threads produced, caused by the inflating agent, followed by the drawing and fixing of the threads thus produced while they are still hot. Examples of the use of the fibres in question are given by filters and padding.

摘要： Novel porous fibers and filaments are prepared from normally solid, thermoplastic, orientable, organic polymers which have reactive or reactable groups pendent from the polymer chain, employing a process which involves reactions of said pendent groups while the polymer is in an oriented condition. One of the preferred polymers is a copolymer of ethylene/ac- rylic acid.

摘要： A method of forming foamed fibers which comprises the steps of forming a melt of a polymer of fiber­forming molecular weight in which is admixed a blowing agent, and a closed-cell-forming additive, extruding said melt through a spinnerette, quenching said melt downstream of said spinnerette under conditions at which bubbles form in said melt, and drawing said melt as it is quenched to produce a foamed fiber having fine bub­bles contained therein is disclosed. The product fibers may contain substantially only closed-cells and/or sub­stantially uniform cross sectional area cells.

摘要： Der Werkstoff dieser Faser weist eine amorphe oder eine teilweise orientierte molekulare Struktur auf, wobei die Oberflächenstruktur Bestandteil einer geschäumten Schicht ist, welche einen Faserkern umhüllt, der im wesentlichen frei von Poren ist. Die Poren sind senkrecht zur Oberfläche orientiert, und ihr Querschnitt überdeckt bei einem Durch messer von 0,01 bis 0,5 µ 1 bis 99 % der gesamten Oberfläche.
