A mesh nonwoven fabric which is seamless and excellent in appearance is provided. A seamless mesh nonwoven fabric is prepared by laminating a first mesh film 20 containing stem fibers 20a stretching parallel to each other in a first direction and branch fibers 20b connecting adjacent stem fibers 20a together, and a second mesh film 30 containing stem fibers 30a stretching parallel to each other in a second direction intersecting the first direction and branch fibers 30b connecting adjacent stem fibers 30a.
摘要:
Extruded net with at least some strands which melt away upon the application of heat while other strands maintain elastic, or other desirable, properties. This netting is advantageously combined with a fabric in which the low melting strands function as an adhesive, while the high melting strands maintain their designed properties in the final laminate product.

A method of making a reinforced laminate, including the steps of placing a reinforcing grid on a first outer sheet of thermoplastic, preparing an elastomeric material capable of forming a tie layer between two sheets of thermoplastic, and laminating a second outer sheet of thermoplastic to the first sheet of thermoplastic and the reinforcing grid with the tie layer of elastomeric material therebetween, whereby the reinforcing grid is held by the elastomeric tie layer in between the first outer sheet of thermoplastic and the second outer sheet of thermoplastic, and the reinforcing grid being displaceable within the elastomeric tie layer. A reinforced laminate, including a first outer layer of thermoplastic, a second outer layer of thermoplastic, a reinforcing grid disposed between the first outer layer and the second outer layer, a tie layer of elastomeric material disposed between the first outer layer and the second outer layer arranged to hold the reinforcing grid but allow slippage of the reinforcing grid in the tie layer upon tensile loading of the reinforced laminate, and wherein the first outer layer, the second outer layer, the reinforcing grid, and the tie layer are laminated together to form a reinforced laminate.
摘要:
Flat, inelastic, dimensionally stable sheet material is formed by stretching parallel elastomeric strands to several times their relaxed length and then bonding them to one or more flat, inelastic webs with inelastic thermoplastic polymer. When the sheet material is heated, the strands contract and the sheet material shirrs. Strips of the flat sheet material can be incorporated in disposable diapers and subsequently shirred to provide elastic waistbands or leg openings.

A method and an apparatus are described for making a filamentary web. One or more strands of roving, each composed of multiple filaments, are spread out to increasing extents until the filaments form a band in which they extend unidirectionally and generally parallel to each other, but are not connected with one another. Adhesive strips, threads or other connecting elements are then transported on a carrier into a working station so as to be positioned transverse to the elongation of the band. In the working station, they are transferred to the band and joined to the filaments under application of contact pressure in the nip between cooperating nip rollers. This converts the band into a unitary filamentary web structure in which the filaments are all unidirectionally oriented.
摘要:
A process of reinforcing a sheetlike substrate by applying a plurality of linear reinforcements comprising a filamentary core having a pre-coating of "hot melt" adhesive to the substrate with at least one of the linear reinforcements applied in a generally serpentine or waveform pattern to provide both in-machine and cross-machine tensile strength and tear resistance. The present invention is also an improved reinforced sheetlike substrate having the linear reinforcements applied thereon in accordance with the process. In one embodiment, adjacent linear reinforcements are applied in an overlapping or interlocking serpentine configuration onto the substrate. In one embodiment of the process, the sheetlike substrate is conducted along a path defined as the in-machine direction while the plurality of linear reinforcing members are fed through a guide member that is reciprocating transversely with respect to the in-machine direction. The temperature of the thermoplastic adhesive is raised above its softening point and then allowed to harden to bond the linear reinforcing members onto the substrate.

An electrical heating element material of a sheet form is provided, which is comprised of a web of a synthetic resin having a plurality of metal conductor wires arranged therein in parallel to one another along the longitudinal direction of the web. The web is folded in succession at predetermined intervals along folding lines inclined at a small acute angle to the transverse direction of the web to form a substantially two-layer parallelogrammatic sheet. Considering the small angle, the sheet is, for practical purposes, rectangular. The electrical heating element material is prepared by supplying a plurality of metal conductor wires arranged in parallel to one another into a cross-head type extrusion die, separately supplying a thermoplastic resin into said die, co-extruding the resin together with the wires to form a web, folding the web in succession at predetermined intervals along folding lines inclined at an acute angle to the transverse direction of the web to form the two-layer rectangular sheet, and then, optionally, bonding together the two layers. The electrical heating element material may be used as a heat-shrinkable cover, which is comprised of a heat-shrinkable synthetic resin member and the electrical heating element material combined with the heat-shrinkable resin member substantially over the entire region thereof.

A process and apparatus for continuously forming a reinforced membrane of fluorinated polymers containing sulfonyl and/or carboxyl groups in melt-fabricable form and, after hydrolysis, the corresponding membrane in ion exchange form. The membrane thus formed has exceptional uniformity, and this membrane so made, when used as the membrane which separates the compartments of a chloralkali cell, offers the advantages of low operating voltage, low power consumption and high current efficiency, and a long useful life without rupture.

A method is described for making a fiber-reinforced composite film sheet (fiber/film laminate) by continuously forming a first planar lap from a plurality of machine-direction (MD) fibers, continuously forming a second planar lap from a single fiber as transverse-direction (TD) reaches which are connected by 180.degree. loops by stretching the fiber between a horizontally diverging pair of chain assemblies, continuously straddling both laps with a pair of co-extruded films which extend sidewardly beyond the loops, vertically converging the films and fibers to form a sandwich, edge sealing the sandwich within strips close to its side edges but inwardly of the loops, lifting the loops from the chain assemblies, sidewardly smoothing and tautening the sandwich, and laminating the sandwich with heat and pressure to form the composite film sheet.The apparatus for carrying out this method comprises a creel and fiber guides for supplying the MD fibers as the first planar lap; a pair of endlessly revolving roller chain assemblies supporting rows of spindles which are arranged to be initially interwoven, subsequently divergent, and finally in parallel movement to form the second planar lap of TD reaches having their loops over the selectively spaced-apart rows of spindles; at least one bobbin and an engagement support stand for supplying the TD fiber to the initially interwoven spindles; a film storage and feed assembly for supplying the pair of co-extruded films; a film turning and expanding assembly for alignment of the films into straddling relationship to the planar laps of fibers and for sidewise expansion of the films; a converging assembly for arranging the MD and TD fibers and the pair of films to form a fiber/film sandwich; an edge-sealing assembly for heat-sealing the sandwich within a strip which is disposed close to the loops at each edge but inwardly of the loops; a film pickup assembly for lifting the rows of loops from the spindles; an edge puller assembly for smoothing and tautening the edge-sealed sandwich; a laminating assembly for heat sealing the co-extruded films, MD fibers, and TD fiber together to form the fiber-reinforced composite sheet; and a winder for winding the sheet into a roll.
