摘要： PROBLEM TO BE SOLVED: To provide a formed body having a cover with elasticity, excellent in three-dimensional formability, good in fitting properties to the body, and also cheap in production cost by constituting at least one of the surface and back covers sandwiching an interlining out of the cover consisting essentially of a nonwoven fabric of the staple having a latent crimping ability and manifesting the latent crimping ability. SOLUTION: This formed body has a constitution enclosing an interlining between surface and back covers, and at least one of the surface and back covers sandwiching an interlining is constituted of the cover consisting essentially of a nonwoven fabric of the staple having latent crimping ability and manifesting the latent crimping ability. The staple constituting the nonwoven fabric is preferably mutually and three dimensionally interlaced. The staple constituting the nonwoven fabric is preferably formed out of at least one of a fiber-formable ester-based polymer, a fiber-formable olefinic polymer and a fiber-formable amide-based polymer. At least the surface cover is preferably colored.

摘要： PURPOSE:To obtain a prepreg and a copper-clad laminated board whose permittivity is low and which are excellent in a heat-resistant property by a method wherein a cloth obtained by treating the surface of a woven cloth of silicate fibers with a silane coupling agent is impregnated with a specific resin varnish. CONSTITUTION:A cloth obtained by treating, with a silane coupling agent, the surface of a woven cloth formed by weaving silicate fibers whose content of SiO2 is at 98wt.% or higher, whose specific gravity is at 1.8 to 2.0, whose tensile strength is at 20 to 82kg/mm and whose modulus of elasticity is at 1000 to 8200kg/mm is impregnated with a resin varnish obtained by polymerizing a cyanate ester resin expressed by Formula I. In Formula I, A represents an aromatic ring or a group including an aromatic ring, B represents a polycyclic alicyclic group of C7 to C20, D represents a substitution group which does not contain an active hydrogen group individually and independently (p) to (r) represent an integer of 0 to 3 individually and independently, the total of (p) to (r) is at 2 or higher, (s) represents an integer of 0 to 4 individually and independently and (x) represents an integer of 0 to 5. Thereby, it is possible to obtain a prepreg and a copper-clad laminated board whose permittivity is low and which are excellent in a solder heat-resistant property.

摘要： PURPOSE:To provide a weaving method so designed that a thin fabric with its thickness below a specified value is woven using such a take-up roller as to be integrated by baking a resin on the surface of a metallic roller, thereby obtaining a high-grade fabric with defects resulting from roller surface conditions avoided. CONSTITUTION:The surface of a metallic take-up roller in a loom is coated with a resin followed by baking treatment to effect integration. The loom is then fitted with the resultant roller, and using this roller, a thin fabric
