SYNTHETIC FIBERS IN COMBINATION WITH OTHER FIBERS

摘要

By manufacturing a fiber (1, 10) the major part of which consists of thermoplastic resin with a large number of short fibers (3, 13) applied to and fixed in a surface coating of thermoplastic resin on bicomponent fibers (2, 12) which form the "core" of the combination fiber (1, 10), a fiber is obtained that is particularly suited as full or partial binding material in a dry-formed fiber product. Owing to the projecting short fibers, good connection and fastening abilities are obtained in the fiber of the dry-formed product. Therefore, tensile strength is obtained in the dry-formed product without breaking the connection between the dry-formed fibers and the combination fibers. The binding is particularly strong and elastic when the combination fibers (1, 10) are creped.
