The present invention relates to fibrillated lyocell fibers which have a fibrillation ratio Q of 20 or more and whose content of microfibers with a fineness of less than 14 mesh and a diameter of less than 2 μm is at least 50%, as well as the use thereof for producing a wipe, which contains cellulosic fibers and 5 to 20 wt. % of fibrillated lyocell fibers.

The present invention is directed to a hemostatic material comprising a compacted, hemostatic aggregates of cellulosic fibers. In some aspects, the hemostatic material further includes additives, such as carboxymethyl cellulose (CMC) or other polysaccharides, calcium salts, anti-infective agents, hemostasis promoting agents, gelatin, collagen, or combinations thereof. In another aspect, the present invention is directed to a method of making the hemostatic materials described above by compacting a cellulosic-based material into hemostatic aggregates. In another aspect, the present invention is directed to a method of treating a wound by applying hemostatic materials described above onto and/or into the wound of a patient.

A GDL cutting system of a fuel cell includes: a laser-cutting device that forms a gas diffusion layer by radiating a laser on the surface of a GDL fabric panel moving on a conveyer; an adsorbing-conveying device that adsorbs and conveys at least two gas diffusion layers cut by the laser-cutting device; a first vision sensor that senses an upper side of the gas diffusion layers cut by the laser-cutting device; and a second vision sensor that senses a lower side of the gas diffusion layers adsorbed and conveyed by the adsorbing-conveying device.

A process and a splitter for splitting a tape of a uniaxially oriented material. The tape is passed in a process direction over a splitting profile having a row of parallel teeth with a cutting edge extending in the process direction. The tape is split to form a tape comprising a plurality of parallel strips interconnected by fibrils. The split tape can for example be used for the production of high tensile ropes.

It is disclosed a method of producing a yarn having the look and feel of natural fibers, the method comprising the steps of preparing a first plurality of man-made textile fibers or a second plurality of natural textile fibers, the first and second plurality of textile fibers being obtained from breaking the first or the second textile fibers under the effect of a mechanical force applied to the first or the second textile fibers. A final blend for producing the yarn, can be prepared by adding the first plurality of textile fibers to a plurality of man-made fibers, or by adding the second plurality of textile fibers to a plurality of man-made fibers, or by adding the first plurality of textile fibers to the second plurality of textile fibers.

An object is to provide a method for producing a liquid-crystal polyester processed product, the method improving the adhesion of a liquid-crystal polyester resin, which is a poorly adhesive resin. As a solution, a method for producing a liquid-crystal polyester processed product, including a step (I) of performing an oxidation treatment on a surface of a liquid-crystal polyester resin formed body including a repeating unit represented by general formula (1), is provided.

The invention presented in this document relates to processes for the preparation of a formulation containing poly(lactic acid) (PLA) and aliphatic and/or aromatic polyesters which plasticize it, and its use in monofilaments and films. The presence of polyesters does not remove the biodegradability and composting characteristics of the raw materials used in the formulation. The invention also concerns products that use the formulation.

In another aspect, the present invention is directed to a method of making the hemostatic materials described above by compacting a cellulosic-based material into hemostatic aggregates. In another aspect, the present invention is directed to a method of treating a wound by applying hemostatic materials described above onto and/or into the wound of a patient.

The present disclosure relates to fibrillated fibers and a method for preparing the same. In the present disclosure, there is provided a preparation method capable of providing fibers suitable for complexing with plastics in a more simplified process. According to the preparation method of the present disclosure, microfibers can be easily miniaturized with little energy by growing fine particles on the microfibers to fibrillate the microfibers, and then applying a shear force thereto, and various physical properties can be expressed from the grown fine particles.

The present invention is a process for converting a multilayer film to a plurality of nano-ribbons. The process includes co-extruding a first film and a second film to form the multilayer film, slitting the multilayer film to form a plurality of multilayer ribbons, and separating the multilayer ribbons to form a plurality of nano-ribbons having substantially flat cross-sections.
