Abstract: A unidirectional reinforcement and a method of producing a unidirectional reinforcement for use in applications where high quality and strength is required. The unidirectional reinforcement includes transversely arranged thin discrete flow passage formed to ensure resin flow properties in a direction transverse to the direction of the unidirectional rovings. Thin discrete flow passage forming means are secured on the unidirectional rovings by means of additional yarns running on the thin discrete flow passage forming means and transverse thereto.

Abstract: A dye-receiving material comprising:a support comprising synthetic fibers; and a three-dimensional network entangled with at least some of the fibers contained in the support. The three-dimensional network comprises a first polymer that is cross-linked by a second polymer; wherein the first polymer is a polyamine comprising primary amine groups, the first polymer being cationic and water soluble; and the second polymer is a water soluble polymer that is different from the first polymer. The second polymer containing repeating units comprising halohydrin and/or epoxide groups that are capable of forming covalent cross-links with the primary amine groups of the first polymer. Low amounts of cross-linking components are needed for high dye pick-up efficiency.
