The present invention relates to a packaging material for use in a pouched product for oral use in order to enclose a filling material. The packaging material is a saliva-permeable nonwoven material comprising fibres. The packaging material is a wetlaid nonwoven material, or, alternatively, the fibres are carded and the nonwoven material is hydroentangled, or, alternatively, the fibres are carded and the packaging material has a basis weight ≤30 g/m.sup.2. 50%-100% of the fibres are cellulose-based staple fibres, and 0%-50% of the fibres are thermoplastic fibres, with % numbers being based on total weight of fibres at 21° C. and 50% RH. The packaging material further comprising at least 10% of a binder, taken as a wt % of a total weight of the packaging material. The present invention also relates to a pouched product for oral use comprising such a packaging material. The present invention further relates to a method for manufacturing of a packaging material for a pouched product for oral use.

The invention relates to a method of forming a biodegradable nonwoven fabric, the nonwoven fabric obtained by this method, and a system of devices for carrying out this method, to be used for the manufacture of cellulosic articles for clean-up work and sanitary products, and medical uses.

The invention provides batting that includes a nonwoven web comprising a specified fiber mixture, the non-woven web having 50 to 95 wt % of a plurality of fiberballs having an average diameter of 3.0 to 8.0 mm; and 5 to 50 wt % of a plurality of portions of the nonwoven web that are adjacent to one or more fiberballs but that do not themselves comprise one or more fiberballs or any portion thereof. The batting has a density of 2 to 12 kg/m3. Also provided are articles comprising the batting and methods of making the batting.

The present invention provides a non-woven fabric for supporting a solid electrolyte in which heat-fusible composite fibers with a crimp are contained in an amount of not less than 60 mass % and not more than 100 mass % and are heat-fused, and a solid electrolyte sheet. The non-woven fabric for supporting a solid electrolyte is excellent in process performance, is satisfactorily filled with a solid electrolyte, is suitable for achieving a thin solid electrolyte sheet, and has few hole defects. The solid electrolyte sheet is excellent in self-sustainability and flexibility.

A method of making mounting mats comprising the steps of: (i) supplying inorganic fibers through an inlet of a forming box having an open bottom positioned over a forming wire to form a mat of fibers on the forming wire, the forming box having rollers for breaking apart clumps of fibers and an endless belt screen; (ii) capturing clumps of fibers on the endless belt; (iii) conveying captured clumps of fibers on the endless belt so as to enable captured clumps to release from the belt and be broken apart by the rollers; (iv) transporting the mat of fibers out of the forming box by the forming wire; and (v) compressing and restraining the mat of fibers to thereby obtain a mounting mat having a desired thickness suitable for mounting a pollution control element in a pollution control device.

A nonwoven includes: framework fibers; an at least in part fused thermoplastic material; and a thermally embossed mesh pattern having a plurality of intersecting embossed grooves, between which a plurality of embossed elevations are arranged. At least the framework fibers are staple fibers. An equivalent diameter of the embossed elevations is smaller than 50% of a fiber length of the framework fibers. A ratio of a width of the embossed grooves to a thickness of the nonwoven in a region of the embossed elevations is less than or equal to 4/5 A ratio of the width of the embossed grooves to a thickness of the nonwoven in a region of the embossed grooves is from 0.5 to 2.

Nonwoven materials having at least one layer comprising cellulose fibers are provided. The nonwoven materials comprise bonded natural cellulosic fibers having high capillary action. The nonwoven materials are suitable for use in a variety of applications, including absorbent products and pre-moistened cleaning materials with metered release of liquid.

A method for covering a portable structure, the portable structure having a frame and a covering, includes the step of: providing the covering, the covering includes a nonwoven having a densified portion on a first face of the nonwoven and a lofty portion on a second face of the nonwoven, and a skin laminated on the nonwoven, or a first nonwoven having a densified portion and a lofty portion, a second nonwoven having a densified portion and a lofty portion, and a skin laminated on the first nonwoven or the second nonwoven.

Methods for forming a touch fastening material are described as including: providing a lengthwise-incoherent layer of staple fibers supported directly on a bed of bristle tips of a brush; needling the layer of staple fibers by cycling needles through the layer of staple fibers and into the brush; then, while the needled layer of staple fibers remains supported on the brush, fusing portions of the staple fibers by at least partially melting resin of the fibers disposed outside the brush; and then pulling the layer of fibers from the brush as a lengthwise-coherent touch fastening material having exposed fastening loops pulled from between the brush bristles.

A method may produce a heat-resistant resin composite excellent in heat resistance and bending properties. This heat-resistant resin composite is constituted of a matrix resin and reinforcing fibers dispersed in the matrix resin. The matrix resin is constituted of a heat-resistant thermoplastic polymer having a glass transition temperature of 100° C. or higher, and a polyester-based polymer comprising a terephthalic acid unit (A) and an isophthalic acid unit (B) at a copolymerization proportion (molar ratio) of (A)/(B)=100/0 to 40/60. The proportion of the heat-resistant thermoplastic polymer in the composite is 30 to 80 wt %.
