The knitted textiles include a knitted structure including a plurality of hollow yarns. Each hollow yarn includes a yarn body and defines a yarn hole extending through the yarn body to allow expansion of the yarn body upon inflation of each hollow yarn through the yarn hole. The knitted structure is configured to transition from an unexpanded state to an expanded state in response to the inflation of the hollow yarns through the yarn hole. The knitted structure has a first porosity in the unexpanded state, and the knitted structure has a second porosity in the expanded state. The second porosity is less than the first porosity such that a visibility through the knitted structure is greater when the knitted structure is in the unexpanded state than when the knitted structure is in the expanded state.

A method of manufacturing a flexible, impact-resistant pad (1), primarily for use in an item of protective wear, comprises the following steps. First, a sheet (16) of impact-absorbing material (3, 4, 4), for example a closed-cell foam is provided. The sheet (16) is cut to provide a piece (16) with a profile required for the pad (1) and this piece (16) is then cut into a plurality of spaced, separate elements (2), which are retained within the required profile of the pad (1). A first, flexible layer (17, 4) of material (3) is provided and one side of same is bonded to the spaced, separate elements (2). The edge (5) of the pad (1) is streamlined by the following additional steps which may be carried out either before cutting of the sheet (16) into the plurality of spaced, separate elements (2) or after bonding of the first, flexible layer (17, 4) of material (3) to the spaced, separate elements (2). First, a contoured mould tool (8) is provided that defines a recess (9) having a shape complementary to the shape required on one side of the pad (1) and a streamlined edge (10) around at least part of its periphery. The impact-absorbing material (3, 4, 4) or the mould tool (8) is heated and the mould tool (8) is then pressed into it to mould it on one side to define the shape that is required. Preferably, the method comprises the further step of bonding a second flexible layer (17, 4) of material (4) to the moulded side of the pad (1). During bonding of this second flexible layer (17, 4) of material (4), the pad (1) is preferably supported on a yielding surface (23) to enable the moulded side of the pad (1) to flatten during bonding. Also provided is a flexible, impact-resistant pad (1) Comprising a first, flexible layer (17, 4) of material (3) and a plurality of spaced, separate elements (2) that are each comprised of an impact-absorbing material (3, 4, 4) and that are bonded to one side of the first flexible layer (17, 4) of material (3). At least some of the elements (2) adjacent the edge (5) of the pad (1) are streamlined around at least part of the periphery of the pad (1).

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).

This invention relates to a washable floor mat comprising a reinforcement layer. The floor mat includes a textile component and a base component. The textile component contains a reinforcement layer which dramatically reduces and/or eliminates edge deformation that often occurs as a result of the washing process. The textile component and the base component may be joined together to form a single piece floor mat. Alternatively, the textile component and the base component may be releasably attachable to one another by at least one surface attraction means to form a multi-component floor mat. The floor mat is designed to be soiled, washed, and re-used, thereby providing ideal end-use applications in areas such as building entryways.

The methods herein relate to assembling an elastic laminate with a first elastic material and a second elastic material bonded between first and second substrates. During assembly, an elastic laminate may be formed by positioning the first and second substrates in contact with stretched central regions of the first and second elastic materials. The elastic laminates may include two or more bonding regions that may be defined by the various layers or components of the elastic laminate that are laminated or stacked relative to each other. In some configurations, a first plurality of ultrasonic bonds are applied to the elastic laminate to define a first bond density in the first bonding region, and a second plurality of ultrasonic bonds are applied to the elastic laminate to define a second bond density in the second bonding region, wherein the second bond density is not equal to the first bond density.

There are provided a soundproof structure, which can have high soundproofing performance in a wide frequency band and in which visual recognition of through-hole can be suppressed, and a sound absorbing panel and a sound adjusting panel using the soundproof structure. A sheet member having a plurality of through-holes passing therethrough in a thickness direction and a sound absorbing body disposed in contact with one main surface of the sheet member are provided. An average opening diameter of the through-holes is 0.1 μm or more and less than 100 μm. Assuming that the average opening diameter of the through-holes is ϕ (μm) and an average opening ratio is σ a parameter A expressed by A=σ×ϕ.sup.2 is 92 or less.

An electroluminescent light source included as a sheet-like structure as part of headliner in a vehicle. The electroluminescent light source is arranged under an outer layer of fabric, as well as under a layer of foam and a layer of nonwoven textile material. The electroluminescent light source lacks a dedicated housing for containing the electroluminescent light source, which allows for the headliner to maintain a flat and uniform surface that is undisturbed by the inclusion of the electroluminescent light source. When the electroluminescent light source is activated, the emitted light has sufficient brightness to shine through the various layers of the headliner to illuminate the interior of the vehicle.
