Abstract: The invention provides a thermoplastic elastomer nonwoven fabric roll that exhibits minimal longitudinal wrinkles and minimal delayed restoration when unrolled, and method and apparatus for producing the same. Thermoplastic elastomer filaments that have been melt-spun are piled on a belt conveyor thereby forming a sheet of nonwoven fabric, that is guided to a rotating roller disposed above the transportation zone of the belt conveyor and peeled off therefrom. Since minimal tension is applied to the nonwoven fabric during processing, the nonwoven fabric can be unrolled with little stretching by applying relatively little tension to the nonwoven fabric. By the method of this invention, a nonwoven fabric roll with unrolling tension of 0.25 g/cm/basis-weight or less can be formed.

Abstract: The present invention is directed to a stretchable adhesive nonwoven prepared by laminating continuous filaments made of a thermoplastic polyurethane resin, which comprises an aliphatic diisocyanate and/or an aromatic diisocyanate, a polymeric diol and a chain-extending agent and has a hardness (JIS-A hardness) of 65 to 98 degree and a flow initiating temperature within a range from 80 to 150° C., into a sheet, and fusion-bonding the filaments themselves with their own heat at the contact point of the laminated filaments thereby to form fibers, and a laminate containing the same. The adhesive nonwoven fabric of the present invention is rich in flexibility and is excellent in adhesion and air permeability.

Abstract: A wet non-woven fabric comprising a highly water absorptive polymer and pulp and a method for producing the same. Since this wet non-woven fabric is excellent in water absorbing property and uniformity, it can be offered as a thin non-woven fabric.

Abstract: A highly water-absorptive fiber formed of a copolymer containing:(a) polymer units from a vinyl monomer having a carboxyl group, some of the carboxyl groups of the polymer units being converted to a Na salt and/or K salt, and(b) polymer units from monomers such as a vinyl monomer having an amino group and a vinyl monomer having a hydroxyl group and an amino group. This highly water-absorptive fiber has high water absorption properties, has almost free from coloring, is excellent physiological saline solution absorption properties and can be produced under usual carding and spinning conditions.

Abstract: A data processing system for a radiation image reproducing apparatus includes an input device for entering an identification code assigned to a radiation image storage panel and data related with an exposure at an exposing device when the storage panel is exposed to an imagewise radiation. The input device is associated with the exposing device.

Abstract: A cassette for use in a radiation image recording and readout system includes a radiation image storage panel including a layer of stimulable phosphor and having an identification recorded thereon, and a casing for enclosing the radiation image storage panel therein. The casing has an opening provided substantially in correspondence in position with the identification so as to sense it from the outside of the cassette. The identification may be recorded in a visual or magnetically sensable form.

Abstract: Synthetic fibrous structures having a soft feel, an excellent luster and a silky feel are produced by forming composite filaments composed of a polyamide and a component having poor affinity to the polyamide selected from the group consisting of a polyester, polyolefin and polyacrylonitrile into a fibrous structure and treating the fibrous structure with an aqueous emulsion of 1.5-50% by weight of at least one of benzyl alcohol and phenylethyl alcohol and having a percent transmittancy of less than 20%, which is obtained by adding a surfactant to the emulsion, whereby to fibrillate the composite filaments.
