摘要： A method for producing ultra fine denier cellulose acetate fibers that entails spinning a spinning solution containing adequately high amounts of cellulose acetate in acetone wherein the cellulose acetate has a falling ball viscosity of 15 to 70 seconds wherein the spinning is conducted through spinnerettes having holes that have a diameter of less than 36 microns followed by drying at a temperature of about 50.degree. to 80.degree. C. at a draw ratio of 0.9 to 1.7.

摘要： Filamentary tow is puddled into a container from an air jet through an air dissipator apparatus, which slows the air-propelled tow by the tow impinging upon the dog-legged surfaces along the flow path within the apparatus and ricocheting therefrom while the propelling air is dissipated from the tow as the tow moves along the flow path and out of the apparatus for subsequent disposition into a container or the like that may be positioned below the air jet and the air dissipator apparatus connected to the end of the air jet.

摘要： Device for connection to the outlet end of a gas jet tow puddler for puddling filamentary tow into a container, the device having a downwardly sloped gas-impervious plate positioned downstream from the gaseous jet outlet and against which filamentary tow impinges, becomes slowed and then cascades downwardly therealong; and a gas-impervious cylindrical shell opposed to and spaced from the exit end of the downwardly sloped plate and against which the filamentary tow travels from the downwardly sloped plate for subsequent slowing and movement therealong and then dropping from the cylindrical shell into the container below.

摘要： Disclosed is a novel tobacco smoke filter material comprising a filter element such as cellulose acetate crimped tow having at least about 1 weight percent of micro acicular crystals of a compound such as sodium carbonate present on the surfaces of the filter element. Also disclosed is a process for preparation of such tobacco smoke filter material comprising immersing the filter element in a solution of the compound capable of forming the micro acicular crystals, followed by removing the filter element from the solution and removing residual liquid, thereby forming the novel tobacco smoke filter material.
