A packaging for sterile packaging application includes: a single layer nonwoven fabric obtained from a nonwoven, the nonwoven including meltblown polymer fibers having an average fiber diameter between 2 μm to 10 μm and a standard deviation of the fiber diameter of at least 100%. The nonwoven is thermally bonded.

The disclosure provides a woven fabric, wherein all warp and weft yarns may be elastic. One or more of the weft and warp yarns may have a stretchable core comprising a first elastic fiber and a second fiber that may be less elastic than said first fiber. The elastic warp yarns may have a twist level with a twist multiplier in the range of 2.5 to 6. In embodiments, a woven fabric may include all warp and weft yarns being elastic, all weft and warp yarns having a stretchable core comprising a first elastic fiber and a second fiber that is less elastic than said first fiber, and the elasticity of the fabric in warp direction is at least 25% and elasticity of the fabric in weft direction (E.sub.weft) is at least 25%, preferably at least 30%, more preferably 40%. In embodiments, the elasticity of the fabric in the warp direction may be at least 25%.

The invention provides a resin molding and a method of producing the same in which sterilizability thereof is secured and discoloration (yellowing) thereof is reduced even when the resin molding is radiation-irradiated under anaerobic conditions (deoxidation conditions). The radiation-irradiated and packaged resin molding is primarily packaged with a packaging material having oxygen permeability and then secondarily packaged with an oxygen impermeable packaging material together with a deoxidizer. The method of producing a radiation-irradiated and packaged resin molding involves a step of primarily packaging a resin molding before radiation irradiation with a packaging material having oxygen permeability, a step of subsequently secondarily packaging with an oxygen impermeable packaging material together with a deoxidizer, and then a step of conducting radiation irradiation. A step of opening the secondary packaging under the atmosphere, following the radiation irradiation step, is preferred.

A method of creating a soft and lofty continuous fiber nonwoven web is provided. The method includes providing first and second, different molten polymers to a spinneret defining a plurality of orifices and flowing a fluid intermediate the spinneret and a moving porous member. The method includes using the fluid to draw the first and second molten polymers, in a direction toward the porous member, through at least some of the plurality of orifices to form a plurality of individual continuous fiber strands. The method includes depositing the continuous fiber strands onto the porous member at a first location to produce an intermediate continuous fiber nonwoven web, and intermittently varying, in at least two different zones, a vacuum force applied to the moving porous member and to the intermediate web downstream of the first location and without the addition of more continuous fibers and without any heat applied.

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.

Disclosed are exemplary embodiments of woven filtration fabrics that include core-sheath spun yarns in either or both of the warp and weft directions.

Polyethylene compositions and finish-free, ultra-fine denier, ultra-high molecular weight polyethylene (UHMW PE) fibers and tapes are provided. The fibers and tapes are made from said compositions that are usable in medical, in-body applications, as well as a process of their making.

A composite hot-melt adhesive mesh film and preparation process thereof, in particular, a composite hot-melt adhesive mesh film and preparation process thereof for bonding metal and non-polar material are disclosed. The mesh film is compounded of a polar polyamide hot-melt adhesive and a non-polar polyolefin hot-melt adhesive mesh film containing a compatibilizer. The mesh film has a high adhesive strength and a durable and stable adhesion, and is especially suitable for bonding stainless steel, aluminum, copper or other metal materials and polyethylene, polypropylene or other non-polar polymers. Additionally, the preparation process is completed in one set of production process from raw material pretreatment to the final preparation of the hot melt adhesive mesh film product, thereby greatly reducing production failures, and providing high production efficiency and low costs.

The invention is an improved macrosynthetic fiber for concrete reinforcement.

Woven irrigation tubing comprises a woven, extrusion coated & laminated tube formed of a high density polyethylene (HDPE) outer layer, a low density polyethylene (LDPE) middle layer and a linear low density polyethylene (LLDPE) inner layer. The finished tubing is treated for ultraviolet resistance. The tubing is tied off at a distal end with a proximal end connected to a pressurized irrigation source. Watering holes are created in the tubing at spaced intervals and the resulting water streams are directed into parallel plowed furrows. The tubing is completely recyclable. The tubing is formed by manufacturing tape for the woven outer tubing cover, stretching the tape along its length to strengthen it, weaving the outer layer from the tape, flattening the woven outer layer, extrusion coating each surface of the outer layer with LDPE, laminating the LLDPE inner layer to the LDPE, reversing and winding the tubing for storage and distribution.
