Abstract: A skin material includes: a design layer; and a base cloth layer. The design layer includes a surface layer and a foam layer. The base cloth layer includes a surface fabric and a back fabric, and a binding yarn that binds the surface fabric and the back fabric. The binding yarn is a thermoplastic resin fiber erected between the surface fabric and the back fabric to form a gap between the surface fabric and the back fabric. The foam layer and the surface fabric are joined. An interior material includes the skin material and a base material to which the skin material is attached. A method for producing the skin material includes joining the surface layer and the base cloth layer via a foamable adhesive to serve as the foam layer.

Abstract: A float textile having an improved optical interference function, containing a float texture yarn formed by combining three or more multi-filament yarns each comprising, as a constituent unit, optically interfering mono-filaments which are formed by alternately laminating layers of at least two polymers having different refractive indices and which have flattening ratio of 4 to 15 and by interlacing the multi-filament yarns to form 20 or less interlaces per meter, used as a warp float and/or weft float component, and having a float number of 2 or more. A spun-dyed textile which is formed by combining a large number of optically interfering multi-filament yarns can provide a float textile which can exhibit a bright color development effect and can expand the utility thereof to room interior and car interior fields.

Abstract: The invention provides a melt-blown non-woven fabric obtained by melt-blowing an ethylene-.alpha.-olefin copolymer having a density of smaller than 0.900 g/cm.sup.3 and a crystallinity of from 5 to 40% or by melt-blowing a resin composition which chiefly comprises said copolymer, a laminated non-woven fabric obtained by laminating as a unitary structure a dry-type non-woven fabric on the melt-blown fabric that is obtained by melt-blowing said copolymer or the resin composition which chiefly comprises said copolymer, and a cataplasm which comprises the non-woven fabric obtained by melt-blowing said copolymer or said resin composition which chiefly comprises said copolymer, a dry-type non-woven fabric laminated on said melt-blown non-woven fabric, and a medicine layer applied onto said dry-type non-woven fabric. The non-woven fabric or the laminated non-woven fabric has excellent elastic property, i.e.

Abstract: A blow-molding apparatus which includes a die for extruding a molten resin; a blow nozzle connected to the die; a split-type mold having separable mold portions and a pinch-off portion provided in a downstream side of the die; device for injecting cooling air and for sucking air received in the mold portions by vacuum through the passages passing through the pinch-off portions of the split-type mold; and porous members embedded in the passages.

Abstract: A blow-molding apparatus in which a lower mold is divided into two parts, i.e. a split-type mold having a ring like configuration and a lower mold, so that the molding of a chime on a drum molded in the apparatus is facilitated. A connecting device, which can be magnetic or mechanical, is provided for selectively connecting the split-type mold to the lower mold for molding.

Abstract: A blow-molding method and its apparatus and a molded drum thereby are improved in that: a lower mold is divided into two pieces, i.e., a split-type mold having a ring-like configuration and a lower mold itself, so that the molding operation of a chime of the molded drum is facilitated.

Abstract: A method for forming a plastic container having an integrally formed chime structure is disclosed. A lower mold is raised toward but does not contact an extrusion die. Molten resin is then filled into the lower mold and subsequently the lower mold is raised into contact with the extrusion die. The lower mold is then lowered from the extrusion die between partable mold halves while resin is simultaneously extruded thereby forming a hollow parison between the extrusion die and the lower mold. The lower mold is then stopped when a parison of desired length has been formed. The mold halves are then closed and the parison is blown into conformity with the walls of a mold cavity formed by the closed mold halves. In the case where the parison length is greater than the axial length of the mold halves, the lower mold is raised slightly after closing of the mold halves and before blowing of the parison.

Abstract: A blow molding method comprising introducing a hot parison of a thermoplastic crystalline olefin resin into a mold cavity and blow molding it, characterized in that the blow molding is carried out under such temperature conditions that the surface temperature, T.degree.C., of the mold cavity satisfies the following expression (1),T.sub.c -T.sub.1 -.DELTA.T<T<T.sub.c +T.sub.2 (1)whereinT.sub.c is the DSC crystallizing temperature in .degree.C. of the olefin resin,T.sub.1 is 20.degree. C. when the olefin resin is a C.sub.2 olefin and 30.degree. C. when it is another olefin resin,T.sub.2 is 10.degree.
