Abstract:
Tufted carpets which are conformable and stretchable make use of a stretchable carpet backing formed from a composite fabric. The stretchable carpet backing fabric is formed of a stretchable elastic net and at least one nonwoven fibrous layer overlying the stretchable elastic net. The fibers of the fibrous layer extend through said elastic net to mechanically secure the fibrous layer to the elastic net and form a unitary coherent elastic fabric.
Abstract:
The present invention relates to a method for manufacturing carpet tiles having excellent dimensional stability which comprises the steps of:(a) allowing a reticulated fabric base having a small thermal coefficient of linear expansion to be contact with the whole surface of the back of a carpet base material,(b) applying a backing material prepared from a composition containing a thermoplastic material as the major component to the resulting composite material, and(c) optionally laminating a fabric backing onto the above backing material.
Abstract:
The adhesion of carboxylated SBR adhesive to polypropylene carpet backings is improved by a coating on the polypropylene of chlorinated polypropylene having a chlorine content of 10-20%.
Abstract:
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 fibrilsand provides strength, elasticity and an aesthetic appearance to the composite material.
Abstract:
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).
