Abstract:
Methods and systems are described for continuously densifying at least one nanofiber sheet using heat and an applied force that can include both compressive and tensile components. Nanofiber sheets densified using these techniques have a more uniform and more highly aligned microstructure than nanofiber sheets densified using a solvent alone. As a result, the nanofiber sheets of the present disclosure have, for example, higher tensile strength and better electrical conductivity than nanofiber sheets densified using other techniques.
Abstract:
Methods of making an artificial leather substrate from leather waste (e.g., shavings, such as wet blue, and/or pulverized trim scrap) and products formed using the artificial leather substrate are disclosed. In one example, the artificial leather substrate comprises a composite web comprising leather waste mixed with a lightweight web, a lightweight web atop the composite web, and another lightweight web atop the first lightweight web. A method of making the artificial leather substrate includes the steps of mixing one or more fiber components, leather shavings, and/or pulverized leather trim scrap to form the composite web; needle punching the composite web; and bonding the composite web.

Abstract:
A method and apparatus are described for controlling a coating head, which exerts a nip pressure to a fibrous web to be coated (102) while the fibrous web is supported by a backing roll (101). An output signal of a sensor (105) integrated within the backing roll (101) is read, thus producing a measured indication of the nip pressure. A number of actuator control values are derived at least partly from said measured indication of the nip pressure. Said actuator control values are delivered as commands to a number of respective actuators (803) that contribute to creating the nip pressure, to control an amount of a coating substance on the fibrous web (103) in the coating head.
Abstract:
A method and apparatus for forming a nonwoven product, including steps of forming a nonwoven web from a material and calendering the nonwoven web received following the forming step on a calender means. The method also including a step of obtaining information pertaining to a number of parameters of the calender means or to the formed nonwoven web from a sensor and controlling the calender means with the obtained information.
