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).

Abstract:
Described herein is a method for producing a biofabricated material from collagen or collagen-like proteins. 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.
Abstract:
A method for providing a textile product includes the steps of providing yarns, contacting the yarns with a support material to form an intermediate product and bonding the yarns to the support material to form the textile product, wherein the bonding takes place by providing a reactive nucleus precursor at a site where the yarns contact the support material, and converting the precursor into a compound having multiple reactive nuclei in the presence of a compound having multiple nucleophilic groups, as well as a textile product obtainable by the method, uses of that product and lignin for use in producing such a textile product.
Abstract:
A moisture-vapor-permeable and water-resistant fiber involves a layer of base fabric, a moisture-vapor-permeable layer, and a water absorption layer. The moisture vapor permeable layer is obtained by coating or laminating the inner side of the fabric with a moisture-vapor-permeable resin, which prohibits the penetration of the water droplets but allows the penetration of the moisture vapor molecules. The moisture absorption layer with intricate and colorful design is composed of binding resin blended with fiber powder and/or inorganic powder, and which is dot-coated or dot-printed onto the inner side of the moisture-vapor-permeable and water-resistant layer. The fiber powder or inorganic powder is highly hydrophilic and highly absorbent in its moisture absorption ability, which, when the clothes are fabricated, can prevent the penetration of raindrops but allows the transmission of the evaporated vapor of sweat through the fabric. Moreover, it is capable of absorbing plentiful amount of sweat.
Abstract:
Textiles treated with hydrophobic dispersions that exhibit superior drying rates and lower spin-dry water contents are disclosed. Polytetrafluoroethylene, polyvinyl acetate, and polyvinyl acetate/acrylic copolymer dispersions are used to treat textiles, including yarns, fabrics, linens, and articles of clothing. The use of dispersions create textiles with a discontinuous treatment of discrete individual hydrophobic particles applied to the surface. The treated textiles exhibit superior drying properties at very low levels of treatment. Also provided are methods for treating textiles with hydrophobic dispersions. The incremental cost to the textile of the treatment is minimized by low levels of treatment and flexibility in application.
