摘要:
Provided herein are mycelium materials and methods for production thereof. In some embodiments, a mycelium material includes: a mycelium material including one or more disrupted fibers, wherein the one or more disrupted fibers is oriented in a z-direction and/or a bonding agent may be combined with the mycelium material. Methods of producing a mycelium material are also provided.
摘要:
A method of continuously manufacturing aerogel using techniques typically associated with the production of nonwoven fabrics. Polymeric fibres are arranged into a fibre web. Crosslinking agent is applied to the fibre web to strengthen the structure. Further strengthening occurs when the polymeric fibres are bonded. A coating may be applied to modify the physical properties of the aerogel depending on application requirements. The aerogel is then finished by undergoing calendering to smoothen its surface and curing to cure the cross links and/or surface coating.

Es wird ein Verfahren zur Herstellung einer Faserbandanordnung (8) mit mindestens zwei weitgehend parallel zueinander angeordneten Multifilamentgarnen (1) vorgeschlagen, welches folgende Schritte aufweist: - ebene Anordnung der Multifilamentgarne (1) in jeweils zueinander benachbarter, weitgehend paralleler langgestreckter Lage mit Abstand (3) zwischen den Multifilamentgarnen (1) - Einbringen von Verstärkungsmitteln weitgehend quer zur Längsrichtung der Multifilamentgarne (1) mit Abstand zwischen den Verstärkungsmitteln in Längsrichtung der Multifilamentgarne (1).
摘要:
A multi-ply absorbent product having a wet scrubbing resistance greater than 120 revolutions and a basis weight of between 30 and 50 grams per square meter. A heated adhesive is applied between two single plies / webs, the multiple plies are embossed according to particular parameters, and the embossed webs are compressed with a marrying roll. The adhesive is heated to a temperature of between approximately 32 degrees C to 66 degrees C for application between the multiple plies. For each ply, the embossed area generally occupies between approximately 5 to 15 % of the total surface area of a surface of the ply, the depth of embossment of the surface is generally between approximately 0.28 and 0.43 centimeters deep, and the embossment of the surface is generally between approximately 0.04 to 0.08 square centimeters in size.

A nonwoven laid scrim includes a carrier and an angled scrim overlying the carrier. The angled scrim includes at least one first assembly of filaments and at least one second assembly of filaments. The nonwoven laid scrim has a main direction and a cross direction, the at least one first assembly of filaments is oriented at a first angle, and the at least one second assembly of filaments is oriented at a second angle. Each of the first and second angles is an off-angle measured relative to the cross direction and the first and second angles have distinct values. The nonwoven laid scrim optionally includes a uni-directional fabric including a plurality of filaments, where the carrier overlies the uni-directional fabric. At least two assemblies of filaments and a first cross direction yarn of the carrier also can define a multi-sided shape with at least three sides.

A method for producing a bale of crimped tow band may include providing a tow band having about 10 denier per filament or greater and about 20,000 total denier or less, the tow band comprising a plurality of cellulose acetate filaments; crimping the tow band thereby yielding a crimped tow band; conditioning the crimped tow band; and baling the crimped tow band to form a bale.
摘要:
Die Erfindung betrifft ein Verfahren zum Herstellen eines Faserhalbzeugs (2) für die Einbettung in eine duroplastische Matrix (15), mit den Schritten: Legen einer ersten Lage (5) aus parallelen, matrixfreien Fasern (22) in einer Richtung (8), und Fixieren der ersten Lage (5) durch Auflegen von mit zumindest einer Komponente der duroplastischen Matrix (15) benetzten Fasern (23) in voneinander beabstandeten Bündeln (14) in einer zweiten Lage (13), wobei die Faserbündel (14) der zweiten Lage (13) sowohl in stumpfen als auch in spitzen Winkeln (α, β) zu der genannten Richtung (8) gelegt werden. Die Erfindung betrifft ferner nach solchen Verfahren hergestellte Faserhalbzeuge (2) und Faser-Verbundwerkstoffe (24).
