A fiber bundle which has a pieced part formed by jetting a pressurized fluid against a fiber-bundle overlap is formed either by directly superposing the ending part of a fiber bundle composed of many fibers on the beginning part of another fiber bundle composed of many fibers or by superposing the end part and the beginning part on a jointing fiber bundle composed of many fibers, whereby the many fibers of the fiber bundles are interlaced with one another to thereby piece up the fiber bundles. The pieced part comprises an opened-fiber part in which the fibers have been opened and interlaced-fiber parts respectively located on both sides thereof, each interlaced-fiber part being composed of a plurality of constituent interlaced parts located apart in the width direction for the fiber bundle.

A first multilayer film is a multilayer film which contains a layer A on at least one surface of a base film, in which the layer A has (1) a polycaprolactone segment, (2) a polysiloxane segment and/or a polydimethyl siloxane segment, and (3) a urethane bond, and the layer A has a glass transition temperature of from 30 to 0 C. A second multilayer film contains a layer A on at least one surface of a base film, in which the layer A has a scratch recovery time of 3 seconds or less at a temperature of 10 C. A third multilayer film contains a layer B on at least one surface of a base film, in which the layer B has a polycaprolactone segment and a urethane bond, and the layer B has average elongation at break of 65% or more at 80 C. to 150 C.

A spongelike structure or a powder having fibers three-dimensionally arranged therein with high dispersibility, whose apparent density can be designed depending on the purpose or utility, as well as a process producing it. A fiber dispersion in which fibers having a number mean diameter in a predetermined range are dispersed in a dispersion medium, and this fiber dispersion is dried to remove the dispersion medium, thereby, a spongelike structure and a powder are produced.
