This invention relates to a lyocell material for a tobacco filter and a method of manufacturing the same, and more particularly to a lyocell fiber having a modified cross-section for a tobacco filter, wherein the cross-sectional shape of a monofilament contained in a lyocell fiber is controlled to increase the external surface area of the fiber, after which then crimps are formed, thereby exhibiting properties equal or superior to those of conventional lyocell materials, even when used in a small amount.

The present invention concerns a homogenous polymer mixture comprising a polymer composition that comprises at least one cellulose ester polymer, which is cellulose acetate propionate (CAP), and at least one other polymer selected from the group consisting of polybutylene succinate (PBS) and polypropylene succinate (PPS), wherein the total amount of said cellulose ester polymer and said at least one other polymer is at least 80 wt. % based on the total weight of the polymer composition. The invention also concerns a method and use related thereto.

The present invention provides a thin sheet with suppressed strain. The sheet according to the present invention has a thickness from 0.1 to 5 mm and is formed of a plastic that contains at least one resin selected from polyamide resins, polycarbonate resins, cellulose acrylate resins, and acrylic resins. A difference between a maximum value and a minimum value of retardation of the sheet is 3000 nm or less. The sheet according to the present invention can be obtained, for example, by subjecting a plastic containing at least one resin selected from polyamide resins, polycarbonate resins, cellulose acylate resins, and acrylic resins to extrusion molding to obtain a plastic in the form of a sheet, and subjecting the resulting plastic in the form of a sheet to vacuum forming, air-pressure forming, or vacuum air-pressure forming.

A resin composition containing a cellulose acylate (A) having, in a side chain, a group having a hydrocarbon chain with 5 or more carbon atoms; a polyester resin (B); and an ester compound (C) having a molecular weight of about 250 or more and about 2000 or less. The mass ratio ((B)/(A)) of the polyester resin (B) to the cellulose acylate (A) is about 0.05 or more and about 0.5 or less. The mass ratio ((C)/(A)) of the ester compound (C) to the cellulose acylate (A) is about 0.02 or more and about 0.15 or less.

A method is described for making a retort container having one or two metal ends. A heat-sealable material is present on one or both of the container side wall and the/each metal end. The/each metal end is seamed onto the container body, and the resulting container assembly is conveyed on a conveyor adjacent to an induction sealing head and then adjacent to a cooling device. A pressure belt engages the upper end of the container assembly to keep the metal end from coming off the container body during the induction heating and cooling processes.

Systems and methods for using microneedle arrays to deliver bioactive compounds are presented. In general, the microneedle array comprises at least three layers: a base layer, a separation layer, and a bioactive layer, wherein the separation layer is situated between the base layer and the bioactive layer. Upon exposure to physiological conditions, the separation layer dissolves and/or disperses, allowing the base layer to be removed while the bioactive layer remains embedded in the outer surface of the skin.
