Provided is a method for controlling a fan (1) which includes a control unit (2), wherein the control method includes at least the following steps: the selection of an operating program (22) of the fan (1) from among a plurality of operating programs pre-recorded in the control unit (2), the operating programs including at least first and second fan control data; and the sending, by the control unit (2), of a control signal including at least the first control data for controlling a motor, which are correlated with at least the second control data for controlling at least one secondary device (24) of the fan (1) selected from among: a lighting device; a gas or liquid spraying device; an acoustic device; and a video device.

Silk performance apparel and methods of preparing the same are disclosed herein. In some embodiments, silk performance apparel includes textiles, fabrics, consumer products, and other materials that are coated with aqueous solutions of pure silk fibroin-based protein fragments. In some embodiments, coated apparel products exhibit surprisingly improved moisture management properties and increased resistance to microbial growth.

A carpet or carpet tile comprising a biobased backing is provided. The resultant carpet tile has advantages in terms of environmental issues and reduces the need for fossil fuels. The backing is made using a backing composition comprising a resin, an oil, optionally a thermoplasticelastomer, and a filler material.

Described herein is a method for producing a biofabricated material from collagen or collagen-like proteins which are recombinantly produced and which contain substantially no 3-hydroxyproline. The collagen or collagen-like proteins are isolated from animal sources, or produced by recombinant DNA techniques or by chemical synthesis. The collagen or collagen-like proteins are fibrillated, crosslinked, dehydrated and lubricated thus forming the biofabricated material having a substantially uniform network of collagen fibrils.

The invention is directed to a composite material comprising a biofabricated material and a secondary component. The secondary component may be a porous material, such as a sheet of paper, cellulose, or fabric that has been coated or otherwise contacted with the biofabricated material. The biofabricated material comprises a uniform network of crosslinked collagen fibrils and provides strength, elasticity and an aesthetic appearance to the composite material.

A biofabricated material containing a network of crosslinked collagen fibrils is disclosed. This material is composed of collagen which is also a major component of natural leather and is produced by a process of fibrillation of collagen molecules into fibrils, crosslinking the fibrils and lubricating the crosslinked fibrils. Unlike natural leathers, this biofabricated material exhibits non-anisotropic (not directionally dependent) physical properties, for example, a sheet of biofabricated material can have substantially the same elasticity or tensile strength when stretched or stressed in different directions. Unlike natural leather, it has a uniform texture that facilitates uniform uptake of dyes and coatings. Aesthetically, it produces a uniform and consistent grain for ease of manufacturability. It can have substantially identical grain, texture and other aesthetic properties on both sides distinct from natural leather where the grain increases from one side (e.g., distal surface) to the other (proximal inner layers).

The invention herein provides biofabricated leather materials, solutions comprising collagen that can be used to create biofabricated leather materials, articles comprising biofabricated leather materials applied to portions of a substrate in a pattern or a design such a lace like pattern, and/or that serve to join end portions of one or more substrates, e.g., to replace stitching and/or adhesives, and methods thereof.

This disclosure provides novel silk protein bonded layered or spun materials and processes that convert the waste leather materials into luxury fabrics exhibiting good dyeability, high brilliance, and excellent color fastness. Described herein is silk processed, coated, repaired, and/or infused faux or bonded leather, or faux or bonded leather articles, and methods of preparing the same.
